MFC calls the default dialog box class object members and methods

This feature is not commonly used, but it is possible to invoke the object member or method of the default dialog class in multi-threaded and callback functions, so make a note of it.

First, declare a global variable to store the default dialog class object pointer:

LPVOID pparam;//dialog Box object pointer

assign a value to the pointer in the initialization function of the default dialog box class:

Pparam = (void *) this;

call the following code to invoke the default dialog box class object member or method:

Cpanoramicplayerdlg *dlg = (Cpanoramicplayerdlg *) lpparam;//where Cpanoramicplayerdlg is the default dialog box class name Dlg->decodeimagerun ( Decodethraedtwo);
