CWnd::OnActivateApp

The framework calls this member function to all top-level windows of the task being activated and for all top-level windows of the task being deactivated.

afx_msg void OnActivateApp(
   BOOL bActive,
   DWORD dwThreadID
);

Parameters

  • bActive
    Specifies whether the CWnd is being activated or deactivated. TRUE means the CWnd is being activated. FALSE means the CWnd is being deactivated.

  • dwThreadID
    Specifies the value of the thread ID. If bActive is TRUE, dwThreadID identifies the thread that owns the CWnd being deactivated. If bActive is FALSE, dwThreadID identifies the thread that owns the CWnd being activated.

Remarks

注意

This member function is called by the framework to allow your application to handle a Windows message. The parameters passed to your function reflect the parameters received by the framework when the message was received. If you call the base-class implementation of this function, that implementation will use the parameters originally passed with the message and not the parameters you supply to the function.
