Learning to use resource files [8]-about hinstance

// Hinstance is used in almost every example of resource extraction. Perform a comparative test: var H, A, F: Cardinal; begin H: = hinstance; A: = application. handle; F: = self. handle; showmessage (inttostr (h); {4194304} showmessage (inttostr (a); {13107942} showmessage (inttostr (f); {4260652} end;

 

The test shows that hinstance, application. Handle, and self. Handle are not the same thing.

Self. Handle is the form handle;

Application. Handle is also a window handle, but this window is very small, on the taskbar;

Hinstance isProgramInstance handle; the same program may have several copies at the same time, each copy of course will have a different handle.
