UseCase1:
- Press mouse left button on windows form control
- Don't move mouse and release the left button
The mouse message will be "WM_MouseDown", "WM_MouseUP", "WM_MouseCaptureChanged" and "WM_MouseMove"
Why does control receive the last receive message
UseCase2:
- Write a custom control inherit from system control
- Override WndProc function, adn write the following code:
public class MyControl2 : Control
{
protected override void WndProc(ref Message m)
{
//WM_LButtonUp message
if (m.Msg == 0x202)
{
return;
}
base.WndProc(ref m);
}
}
- Repeat the action in usecase1
the mouse message will be "WM_MouseDown", "WM_MouseUP",
Why does the last MouseMove message disappaer
