threads try to interact with the same data or resources at the same time. When this happens, the problem becomes very complex and difficult to debug. To make things worse, multithreaded code usually seems to work during the initial development period, but in the production process it fails because of unexpected situations where multiple threads interact with the same data or resources at the same time. This increases the risk of multithreaded programming! Because it is very difficult to design

Step 4th: Draw the appearance of the control To give the control a visual look, we need to place the logic in the Paint event. Then, each time the control needs to refresh its visual appearance, it runs the logic. The Paint logic in Windows forms uses the classes in the GDI + section in. NET. These classes basically in

visual| Create | Control Step 2nd: Change the base class Classes created in the control library are automatically named UserControl1 and, by default, inherit from the UserControl class. If we want to create a composite control, it's very easy to just drag the other controls from the Toolbox onto the design surface. However, since we are creating our own controls from scratch, we need to make some changes.

) Void GetVoice(SpeechLib.ISpObjectToken ByRef) Int32 Volume ... However, this code does not work for all COM objects. For some objects, you must use COM reflection. This column will give you an overview of why and how it is implemented. Why do you want to use reflection on an object? I found that reflection is very useful for debugging and logging, and you can use it to write a generic "dump" routine to output all the content about an object. The code in this column is sufficient to allow you

Every day, programmers of VB6 start to transfer to. NET for development. The primary problem they face is getting used to the object-oriented Golden laws in. NET. Therefore, the forum will repeatedly hear netizens discuss how to access forms in Visual Basic. NET 2003. Earlier, I published an article on the solution to this problem. By rewriting Sub New, I used the Me keyword to get an instance of another fo

allows them to access the attribute in a unified manner, this expands the potential risks. Is there some strong type constraints that allow dynamic access to members?

As long as they have Members defined by the corresponding dynamic interfac
