CMFCButton * MFCB=(CMFCButton *) GetDlgItem (IDC_MFCBUTTON1);

MFCB - & gt; SetFaceColor (RGB (0, 255, 0));
I call this in the main window class can change the color, but call this is an error in the other classes,

CodePudding user response:

GetDlgItem API prototype is HWND GetDlgItem ( HWND hDlg , int nIDDlgItem);
Thus gain control of other Windows, you have to specify a control of the parent window
You now that is the main window class (theApp m_pMainWnd=XXX registration window), you can use the AfxGetMainWnd ()

The CWnd * pMainWnd=AfxGetMainWnd ();
If (pMainWnd)
{
CMFCButton * MFCB=(CMFCButton *) pMainWnd - & gt; GetDlgItem (IDC_MFCBUTTON1);
If (MFCB)
{
.
}
}

Other classes call I how to pass the HWND, can call the class, other class cannot call
