From: http://www.cnblogs.com/powerbuilder/archive/2012/03/11/2391128.html The data window of the Grid type in PB is the most widely used type. Features: quick creation and easy location adjustment. After running, you can adjust the column width conveniently, column location, the most efficient operation. However, the line color of the data window type is fixed and cannot be changed (you can modify the memory data through APIS or third-party controls)

According to the Message response method, the window is divided into two categories: Mode window and mode window. In the mode window Before the operation is completed, you cannot enter another window to perform other operations. Used by the user to confirm important messages You must provide feedback before continuing other operations, such as the error Prompt window. Non-mode windows are different. You can open multiple instances at the same time and switch to any instance at any time. The most

1 Preface In the practical application, for some large-scale application system, the application business logic is quite complex, if the application system adopts the traditional client/server architecture, the business logic is too centralized and the client, will overload the client. In addition, once some business logic changes, all client applications must be changed, which will lead to the difficulty of application distribution, an effective solution is to apply the logical structure of th

PowerBuilder is recognized as one of the best Database Front-end development tools. However, PB is monotonous in user interface processing for a long time. The most obvious example is, all window controls do not support transparent colors, that is, transparent. In versions earlier than PowerBuilder 7, the progress bar is not provided, so most programmers always use two Rectangle controls in the program to program the progress. In this way, the Progres

The Yield () function isIt is a very useful function in PB program control. If you can use it properly, it will certainly make your program more user-friendly. The Yield () function transfers control to other graphical objects, including non-PowerBuilder objects. This function detects message queues. If there is a message, the message is taken out. This function returns a Boolean value. If a message is extracted from the message queue, the function re

I have seen some petabytes of data on the Internet, and VB's friends have a lot of time to get the IP address. So I found some information on the Internet, modified it into a convenient dll library for calling, and supported multiple NICs, let Pb and VB use a function call. Haha.Note: pb10 and above are added as follows: alias"Foo; ANSI" :Http://www.cnblogs.com/Files/SummerHeart/GetIP.rar PS: the dynamic library has been updated. I am very grateful
