How to control DATAWINDOW in PB modify column properties

Application in the preparation of management information systems, typically encounter a common problem is how to control under different conditions data in the table columns, such as for the same DATAWINDOW different users have different operations (such as for data entry personnel can change data , and for general inquiries, staff can not change the data), following on the payroll of a simple example to demonstrates the use of PB Ruhe in DATAWINDOW Lie of a modified form of control.

Basic payroll as follows:
Code name variable working hours of the basic wage wage wage jobs pay subsidized intellectuals
code name workdata basesa movesa stationsa bt othersa
char varchar char decimal decimal decimal decimal deciaml

There are two ways in PB can control the column attribute, one static, the other is dynamic ways. The so-called static approach is adopted in the column attribute option to achieve. Way is to use the so-called dynamic programming. Are introduced respectively:

First, the static method

(1) select a column in the datawindow MOUSE right after the point, select "properities" pops up after the system, a label, select "Edit" tab to "Display Only" option to the system to have more;
(2) or select the "Expression" tab, in the "Protect Express" fill in "1";
(3) or select the "Expression" tab, in the "Protect Express" fill in conditional expressions, such as working hours, staff can not be changed less than one year, then write "if (daysafter (date (workdate), today () ) <= 365,1,0) ";
(4) in datawindow in the value of a column of the Tab Order system to 0, the column due to lack of focus and not be modified;
(5) in the DataWindow Painter state Select Rows menu, then select the Update Properties, pop Specify Update Properties dialog box, set the Allow Updates empty.

Second, the dynamic modification method

(1) set for the protection of the entire Datawindow way: Using DataWindow Object The ReadOnly property can be set for the protection of the Datawindow way.
The syntax is: dw_1.Object.DataWindow.ReadOnly = value or dw_1.Modify ("DataWindow.ReadOnly (= value)"), including: value that Datawindow is read-only (read-only) state, it has two values : Yes and No. Yes that makes Datawindow as read-only; No on the contrary, the default value is No. For example: If you want Datawindow set to conservation, the corresponding event in the script contains the following code:
dw_1.Modify ("DataWindow.ReadOnly = Yes") or as:
dw_1.Object.DataWindow.ReadOnly = Yes
(2) protects only certain columns Datawindow
Method 1: Use column Protect property
The syntax is: dw_1.Object.name.Protect = integer or dw_1.Modify ("columnname.Protect (= integer)").
Parameter Description: cloumnname: In order to protect the column names; integer: the column to protect the state, a value of 0 or False when the column is not protected; value of 1 or True, the column is protected. For example, to set the column name to protect the state, the corresponding code: dw_1.Object.name.Protect = 1 or to: dw_1.Moidfy ("name.Protect = 1")
Method 2: Use column TabSequence property, in the program execution as needed TabOrder the column is set to 0, so as to achieve the purpose of protection.
The syntax is: dw_1.Object.name.TabSequence = number or dw_1.Modify ("columnname.TabSequence (= number)")
Parameter Description: columnname: to protect the column names; number: the column TabOrder value (0-32000).
For example, to set the column name to protect the state, the corresponding code:
dw_1.Object.name.TabSequence = 0
Or: dw_1.Modify ("name.Tabsequence = 0")
Method 3: Using the modified column ED99v properties DisplayOnly property values.
The syntax is: dw_1.Object.columnname.Edit.DisplayOnly = value or dw_1.Modify ("columnname.Edit.DisplayOnly (= value)")
Parameter Description: columnname: to protect the column names;
value: that the column is to show only (DisplayOnly) state, it has two values: Yes and No. Yes that does not allow the user to enter data (display only): No, by contrast, the default value is No.
For example: if the column name is set to only show events in the corresponding script contains the following code:
dw_1.Object.name.Edit.DisplayOnly = Yes
Or: dw_1.Modify ("name.Edit.DisplayOnly = Yes")
Although not with this method can be modified when the column but the column will be the focus of these other methods can not.

Third, selective protection of certain lines

DataWindow above methods will work for all lines, but to protect only some of these lines, you need to use the column to protect (Protect) attributes (values with the above method 2), but this is achieved in the establishment when the DataWindow . Methods: the DataWindow Sketchpad (Painter), double-click the appropriate column, the pop-up Column Object dialog box, select the Expressions page, write in the box after Protect if (conditional expression, 1,0). Flexible use of conditional expression can get a variety of protective effect.
(1) only allows to modify the new row inserted
In a DataWindow, sometimes there is a demand: do not allow the existing data can only browse changes, only the data entered by the user before allowing the new changes, then the expression is:
if (isrownew (), 0,1), or if (not isrownew (), 1,0)
(2) the protection of a column other columns according to the data
Such as staff salaries management, more than 5 years of work experience only when allowed to enter the intellectual subsidies (bt), bt the Protect are shown after the box: if (integer (mid (string (today (), 'yyyymmdd '), 1,4)) - integer (mid (workdata, 1,4))> 5,0,1)
(3) to protect the line can be determined only at execution time, and changing the management of such wages, assuming that only the wages of wage changes is change the input by, and generally only in the implementation of the conditions need to be established a variable, which requires the establishment of DataWindow data when a search for the specified parameters (such as the flag), then the column can be modified after the box Protect (user_name is the DataWindow in a, on behalf of the importer's name) :
if (user_name = flag, 0,1)
Also note that in practical applications the actual type parameters.
(4) add a flag in the table column
Basically, these methods require the line to protect certain rules to follow, no rules when these lines when the corresponding table in a marked increase in the specific column (set out name flag), values of 1 and 0, Protect in the other column and then the box directly after the flag of the expression. Run-time if the line flag = 1, the corresponding column in the bank is protected. Column value for the flag amendment, by the data administrator to modify or under certain circumstances flexibility in the program settings.

4 Promotion Practice Cheats

I entered the HQT group marketing marketing management center has been busy traveling around the country to visit see the market, with many divisions during the Zero to managers, distributors, etc. to discuss various problems of the market. I am now on the promotional activities of the essence of the actual operation of some cases collect and organize data bit written to provide you more information.

Cheats 1: Pulse Promotions Law

Interviews: HQT Marketing Manager, Beijing Branch

Some experts have said that more and more like factories and businesses promote the "weak", eat a token gesture. But other experts have said: or promotion may not even chicken bones. The face of competition can only wait helplessly to escape.

Now, with the "feel consumption" era, consumer buying habits has undergone great changes. Consumers become more "free." Therefore, careful planning is important in various forms of promotion. I think that promotion, we should first clear to whom the communication, identify the recipient, dissemination of any information content, when and where to spread. In the specific planning, there are a few must do:

1, accurate positioning, with a clear theme. In the end is communicated to the sale of consumer brand image or reality.

2, determine the best promotions. In addition to careful advance planning and staffing, but also have a good program to purpose and thrust deep into the hearts of everyone, and fully mobilize the enthusiasm, but also detailed on the promotional staff promotions and details of the training.

3, determine the time, promotion time, sooner rather than later. The best three days earlier than its rivals, so as not to pre-empt opponents. Even the best planning should grasp this opportunity.

4, create a good atmosphere on site. If POP posters to the color, shop music to be just right to stimulate the customer's purchase intention.

5, to develop an appropriate sales targets and incentives.

6, control of marketing costs, "to have the system should", so as to have better results.

7, make assessment summary, accumulating experience for the next promotion.

Finally, there are four points to note: 1, investigations are in place to promote dislocation; 2, sources to be well prepared; 3, activity-free remote site, where customers rare; 4, preferably controlled within a week (weekends date).

Cheats 2: to create a warm

HQT dealer in Changsha, Hunan

In fact, the idea should be a lot of promotion, but for the holidays, the most important thing is to create a festive atmosphere, direct consumers must make warm hearts. Now I during the Spring Festival (New Year's Eve to the fifteenth day) of the operating mode to share with you:

First: Welcome Message from the past "welcome" to "Happy New Year." But do not underestimate such a small adjustment and the blessing of such an old fashioned language, during the Spring Festival, which is very effect. We can clearly feel a phrase, every customer into the stores seem exceptionally happy, and with the same "Happy New Year" to respond to Purchasing Guide, this has suddenly narrowed the distance to each other.

Second: clever "red envelope." During their normal operation, we generally do not discount, but during the holidays if subtly let, will attract customers. Who started the fourth day, we will give a pair of shoes each customer a red envelope, a coupon worth 19 yuan, while a small percentage of concessions, but in our traditional Chinese red envelope is given to others in blessing and financial gas.

In fact, the Chinese New Year this time, we do not care about it, plan a cheap. And I trick is to make an issue of numbers, "19" with "to a long long time," meaning that next year all the best. Facts proved that this is very effective, according to my rough statistics, 30% discount coupon to buy in the secondary next day. In fact, we do not advertise, is expanding through word of mouth of customers affected. Word of mouth is the best ads.

Third: special gift. Promotion that is common practice to send gifts, but the key question is the right time to send the right things, like shoe polish before sending the way at every turn has been nothing new, and, in many customers view, these should all be a necessity, so This required that we carefully pondering.

17 the first month of this year's Valentine's Day in the West, our approach is: a pair of shoes the day of female customers, we will send purse or belt, in the traditional view, these things are "men control the money to live," or "bind beloved man, "meaning; male customer a pair of shoes we'll send him roses, let him give his sweetheart. Customers think that we would like the thoughtful, especially women, said customers did not expect, it is very moving.

Cheats 3: find the ones who enjoy the best points

Interviews: HQT Fujian Company

From my own experiences in the past operations, promotions, including holidays, promotions, designed to deal with seasonal products and brand image promotion, this promotion success mainly in three aspects: First quarter new promotional push; Second Christmas New Year's Day and Spring Festival and other major festival activities; third, and forth to open new store opening or save popular. From a consumer point of view, the promotion of their biggest attraction is that tangible benefits. Therefore, the preparation before the promotion, consumers must demand research, finding good none other programs. Here is what I previously had a successful operation of several ways:

First, according to consumer spending sent various different red envelope, this approach is ingenious discount. November 1, 2003 in Zhangzhou, Fujian, we do "HQT heart * red envelope Love" promotion that has taken this form, the day sales of more than 40,000, while sales to November 5 to 13 million and more, to create Footwear sales in Zhangzhou market miracle.

Second, start the end of the quarter none other projects. None other can have different forms, such as through the dial to have shoes to fight for their customers likely to get none other programs, such as direct use of the promotional section on the label. Of course, the most effective of the program or the introduction of systematic none other - to buy the corresponding number according to the proportion of none other.

Third, the clever bundling. For instance, we operate in Quanzhou, Fujian Province are: activities, we all promotions under paragraph style, do a few portfolio tied series, there are five pairs of combinations, 10 pairs of combinations and so on. Of course, this is mainly for families or groups of sales.

In short, none other is always the consumer interest. However, do let promotion before, we must do the budget, it is very important.

Cheats 4: old customers with promotions tied tight

Interviews: HQT Anhui, a dealer

Whenever the festival into the mall or shopping pedestrian street, greets you are all promotional activities, such as: how much to buy back the number, discount sales, what gifts and so diverse gifts of all businesses have struggled, displaying his brilliant idea to to improve their sales.

Years of operating experience HQT store, steal that discount, rebate is not a permanent holy grail. Promotion aims to increase sales, but its object or customers. Blind pursuit of immediate sales, discounts in the festival would lose old customers discounted pre-purchased. Toyota automobile market in China against the background of wild price reduction, price reduction is not taking into account the hundreds of thousands of old users. February 28, 2005 they announced the Accord is 2 million, the grounds that parts made, but they are very well explained to the old customers, which makes the old users to balance the mind, after all, old customers are the source of their profit ah!

Today's society is often said that word is people-oriented, and we all do business with customer-oriented, I think that promotion should focus on the customer. During this time, I just did a promotion with the theme: "returns the old customers, HQT shoes TM to, HQT old moccasins value of 38 yuan for HQT shoes." Activities after the news spread, some customers put four or five years ago HQT old moccasins brought, I gave them a price discount in exchange for the new shoes on feet away. My heart happy: The first return of these old customers over the years, and second, I retain the old customers of this group. In fact, this shoes is not worth one point for me, but the shoes alone, so that the benefits to the old customers, others have nothing to say. Some old customers say oh! My shoes are still lost, next time I have to keep the shoes. I said Yes, so after that we still do. The promotion was successful, it will eventually find the HQT customers added value.

365 days a year, dozens of small festivals, and holidays have different groups, such as the fine Chinese tradition of filial piety for the elderly, of course, Mother's Day promotion a great time. I bought a set from a flower shop in many carnations, ad design is: buy shoes, get carnations mother, daughter, dedicated to his mother's love. This promotion is indeed successful, the customer not to buy your shoes, carnations, but the customers come to the store, you remind her mother to buy a pair of shoes, and the customer to buy carnations for mothers, we have for her to good and ready.

Chinese festivals are many reasons for promotion with many a word, everything for the customer, as long as the festival do not forget your genuine customers then approved, there must be a number of holiday promotions without digging treasure!

Baidu stock market "crazy" hidden undercurrent

Baidu listed on Nasdaq the day before yesterday, an initial public offering for sale of 404 million American depositary receipts, sold to 27 U.S. dollars to close at 122.54 U.S. dollars, up 354% transfer offer price, financing 109.1 million U.S. dollars, up 4.0 billion market capitalization dollars, is satisfied that IPO stock market five years the highest growth companies, has become the grand listing another shocked the Chinese IT companies.

The reason why Wall Street investors today to win the favor of Baidu, created 99 years since the Internet bubble was another miracle, is that U.S. investors on the development of Baidu good expectations. Since its launch in 2002 Baidu Chinese search service, the unique advantages of relying on the Chinese search technology, has been recognized by Internet users, market share, floating way up, catch up with Sohu, beat 3721, even the second quarter of 2004 and beyond Google Chinese, sit tight in the Chinese search the top spot, accounting for 33.1% of the market share of impressive performance. In addition, large groups of Internet users also given a golden opportunity to Baidu. CNNIC China Internet Agency statistics show that China's Internet users increased dramatically in recent years, and now is 115 million, accounting for 8% of the total population, such a huge market on the Chinese search services is enormous. According to statistics, the average Internet users every day with a baidu, rooted in the world's largest customer base of Baidu, the largest of its undoubted potential. Americans look at Google quickly "fortune", his outstanding performance in the stock market Jiaoren been encouraged by the overseas listed Baidu, claiming that "China's Google", directly to shorten the distance with the Americans, so that investors feel elan to an increasing prevalence of the Chinese search company Baidu stock on the pursuit of the natural and normal thing.

But Baidu results get shocked the industry, while there are many places of concern. In the first quarter, Baidu's revenue amounted to 5.2 million U.S. dollars, the profit has 30 million. The first day closing price of shares has soared and 354%, up to 2000 times competing price-earnings ratio, 66 times higher than the number of pre-, while Google stock trades at 75 times, Yahoo is only 70 times. Highlight such a high price-earnings ratio of stock market mania, the analogy a little crazy not to use too. This is the place cusp on Baidu, once a company has any sign of trouble, the stock plummeted, economic collapse, Baidu is the inevitable out of the. 99 years of the Internet bubble era, I wonder how many brilliant passing. COM company overnight out of people's attention, warning, guide for the future. How to market the high expectations to actual results, Baidu has become the most urgent task.

However, Baidu worries so much more than this. The world's largest search provider Google, Microsoft had to take the limb, won over the Chinese vice president Kai-fu Lee, president of China want any of its to increase the strength of Chinese search input could therefore evident. Just in the Chinese search market, Baidu has a firm footing for any reason guarantee not subject to capital, technology, Google, more powerful attack? Chinese search market, ranked third last year, Yahoo acquired the first Chinese search service 3721 to provide companies accelerated the pace of expansion in China, its impact can not be ignored. And some small and large portal search site search service also launched a separate piece of cake, although the moment they do not have the strength to compete directly with Baidu, but the strong momentum of development, after three years, five years later, perhaps there emergence of a new Baidu. Baidu has to face all of its competitors to snatch market share, make great efforts to consolidate its Chinese search market in the first position.

Of course, the emergence and resolution of all issues is the source of Baidu itself. Search market is a very demanding technical innovation and the market, who is a technology leader and anyone can fight to the user, the current search with Baidu in the Chinese leadership, but what happens in the future, Baidu will use the money on the stock market cycle where, yet concern. For others, Baidu has also encountered a lot of trouble. After anti-Baidu alliance, criticism of Baidu copyright infringement, pornography, under the right, if the facts established after the choice of road Baidu, choice of revenue model will need to re-positioning. Baidu will address these issues, whether a complete and mature companies in front of investors, but also the test of time.

But anyway, Baidu listed for its future success of the development of sufficient funds long as they keep excellent performance, continuing technological innovation to solve the problem well in the development process, Baidu Yi Ding Hui glory for ever, in the Chinese Internet enterprises example.

On FreeBSD5.2 common operations (setting) changes

1. Chinese locale
FreeBSD 5.2 currently supported by the Simplified Chinese locale has the following:
zh_CN.GB18030
zh_CN.GBK
zh_CN.EUC
zh_CN.eucCN
As zh_CN.EUC is not a formal Chinese locale, FreeBSD 5.2 Release of XFree86 removed the support of zh_CN.EUC only support zh_CN.eucCN, for zh_CN.GBK and zh_CN.GB18030 in most Chinese ports that have not yet appropriate support. Is still zh_CN.eucCN (using GB2312 encoding) locale is most formal, but also the most mature.
The Chinese locale set methods (bash, can be used chsh to change, fcitx input method):
[Code: 1:4623 c8c5ca]
# File / etc / profile
export LANG = "zh_CN.eucCN"
export LC_CTYPE = "zh_CN.eucCN"
export XMODIFIERS =''@ im = fcitx''[/ code: 1:4623 c8c5ca]
Zh_CN.eucCN by the zh_CN.EUC to trigger the ports of some new problems. If fcitx to start, but the control panel can not display Chinese characters. The solution is to open / usr / ports / chinese / fcitx / Makefile, change all the strings zh_CN.EUC zh_CN.eucCN can.

Of course, you can still set zh_CN.EUC, but you need to ln a zh_CN.EUC the locale:

[Code: 1:4623 c8c5ca] cd / usr / share / locale & & ln-s zh_CN.eucCN zh_CN.EUC [/ code: 1:4623 c8c5ca]

2.X under the best terminal gnome-terminal
If you use bash, and like the Linux prompt is displayed, you can / etc / profile add the following:
[Code: 1:4623 c8c5ca] if ["$ BASH"]; then
PS1 =''u @ h: w $''
else
if ["` id-u `"-eq 0]; then
PS1 =''#''
else
PS1 =''$''
fi
fi [/ code: 1:4623 c8c5ca]
If your gnome-terminal does not make any settings, / etc / profile will not play any role. Can be set as follows:
[Code: 1:4623 c8c5ca] start gnome2 (startx / usr/X11R6/bin/gnome-session) and start the gnome-terminal, open the menu and click on: Edit -> current profile (U )..., open " Title and Command "tab, select the" run shell command "after the closure can be. [/ code: 1:4623 c8c5ca]

3.mozilla other browser plug-ins (Flash, acrobat):
First, install linuxpluginwrapper the port:

[Code: 1:4623 c8c5ca] cd / usr / ports / www / linuxpluginwrapper & & make all install clean [/ code: 1:4623 c8c5ca]
And then in / etc under the accession libmap.conf which reads as follows:
[Code: 1:4623 c8c5ca] # / etc / libmap.conf for FreeBSD 5.x
