Why would you want to? This method is called automatically by the framework in MFC when the Window is first being created, and can only be used at that point.

You don't call OnXYZ type functions, they are called by the framework upon receiving messages. These functions are called message handlers, because they handle messages for specific types of windows events.

For more info check the documentation on Message Handlers[^]

On a sidenote, OnCreate isn't supposed to fill in the passed struct - it is provided by the framework, who got all the parameters from the function that created the new window, e. g. CreateWindow()[^]

Hello, you would not call OnCreate programatically, OnCreate is called by MFC framework.

If you are having trouble creating you main window, I believe the solution here will help you: Document View Architecture in VC++ MFC[^]

C#

int CMyView::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
   if (CFormView::OnCreate(lpCreateStruct) == -1)
      return -1;

   // TODO:  Add your specialized creation code here

   return 0;
}
