PowerBuilder provides 4 pronouns, which are this,parent,parentwindow,super, which can be used in place of object names to refer to objects, thereby enhancing the portability of programs. For example, suppose that there is a statement close (W_main) on the clicked event with the key "exit" in the window W_main, which closes the window W_main, and when the name of the window chan

The language is naturally invented for people, so there are a lot of people-related words and the Division is very fine. when we mention a specific person, we generally say the name directly. but sometimes it is generic, or I have already mentioned the name, and it will be clear if I use a short name later. this requires a pronoun. as the name implies, a pronoun refers to a person, a person, or some

An application example of indefinite parameter in C language: indefinite parameters as a special skill of the middle-C + + language was praised by many people, but in fact this technology has not been applied much. I don't see much application except formatted output. The main reason is that this technology is more cumbersome, side effects are more, and in general the overloaded function is enough to replac
The connection breaks after the data source indefinite period (workaround: Set up since the connection is closed and reconnect automatically.) The question is described below):
The original configuration file of the data source is as follows: (Note: 2 rows of Red line conflict)
The modified data source configuration is as follows: (resolve the problem of indefinite time database connection interruption)
My requirements are as follows:
There are a lot of suppliers whose inventory data needs to be compared by product by supplier by time period, and a chart is generated at the same time, that isUse zedgraph to generate an indefinite Curve
I suggest you paste a picture.
I will summarize other implementation methods after this project is completed. What troubles me is:
How can we draw charts by selecting the number of suppliers and the time period? Th

There is a series of integers, the number of numbers is indefinite, a total of N, to find out the number of the most frequent (the original question is to find the number of occurrences greater than the N/2)
What is the general algorithm for this problem?

Data Source processing for an indefinite (dynamic) Report, report
Dynamic Column reports are a type of dynamic reports, which are common in report applications. Because these types of reports cannot determine the number of columns in advance, they cannot use a fixed column expression in the report. What's more tricky is the preparation of the report data source, because SQL does not support the result set of an in
these three statements, how comfortable should we be ~, Therefore, we want to use the following statement:
# Ifdef _ debug
# Define debug (Info) printf (Info)
# Else
# Define debug (Info)
# Endif
In this way, we can use a debug statement when writing code. We can open the macro toggle _ debug, and all the debug (Info) macro definition information will be replaced with printf (Info), and closed will be replaced with null, so it will not be compiled. Well, this is much more convenient. You can us
In general, it is relatively simple to horizontally center a fixed-width block element, and we only need to set the width of the block element and set margin:0 Auto. However, for block elements that cannot be set to a fixed width, this trick does not work.Let me introduce the three commonly used methods to set the horizontal center of an indefinite wide block element.First: horizontal centering with float+relativeCSS code:.
