As we all know, a workbook in Excel can have more than one work form (worksheet), and each form can be controlled flexibly by a label in the lower left corner (see figure I), and Visual C + + has similar controls, such as setting in the Output window: Build,debug, Find in files and results, such as Label control (figure II).

In addition, this article is suspected of instigating C ++ programmers to learn Java or Java programmers to learn C ++, which is easily disgusted by the two strong supporters. There is no way. I alw

The method that enables C++builder to use the DELPHIVCL class library is based on a more general way of using DLLs in Windows. In practical application, the VCL control is found to be converted to DLL library, and DLL is called dynamically in C++builder. This method applies to Non-visual VCL controls.

Recently I learned C # network programming. I want to automatically log on to the web page and submit get/post information, and then realize loop login to continuously send packets to the server, the server sends a message to the client to record the account and password that can be logged on, so as to bypass the verification code and dynamically capture the logon location. However, due to the small amount of information and slow progress, the followi
I went back to my bedroom last night and saw my roommate being troubled by a C # class assignment. The assignment content was to write a verbal training program to add questions at will. So I decided to save them if I liked to write C.Create dynamic controls

The opened event that is triggered when the ToolTip control is displayed.
An example is followed to illustrate how the ToolTip control is used .Create a blank application project with the Windows store named "Toolti

C # prohibits direct access to controls across threads, InvokeRequired is created to solve this problem, and when a control's InvokeRequired property value is true, it is stated that a thread other than the one that created it wants to access it. At this point it will call the new MethodInvoker (Loadglobalimage) internally to complete the following steps, which ensures the security of the control, you can u
Summarizes the common library functions in C language in Linux-String Conversion, character testing, and memory control.
When there is no IDE, it is necessary to remember the name, parameters, basic usage, and precautions of some common library functions.
Refer to the Linux_C_HS.chm directory. I roughly divide common functions into the following categories:
1. Memory and string
Story background: The Java Group's small partners need a can in IE (or 6 ...). The screenshot below and return to the Web page function, but IE is very cumbersome to do (may not be able to do), so found me to write an ActiveX control to implement this function, think that there may be other small partners need this function, so the PO out for the needs of people to use, of course, can also be used as learning C
Statements are always executed sequentially: The first statement is finished, followed by the second, third, and so on. This is the simplest case, in order to better control the operation of the statement, the programming language provides a variety of control structures to support more complex statement execution. Let's take a look at the control methods provide
