1, the fixed window size, the maximum value is (600, 400), the minimum is also (600, 400).
Void CMAINFRAME :: ONGETMINMAXINFO (MinMaxInfo Far * LPMMI)
{
LPMMI-> PTMaxTracksize.x = 600;
LPMMI-> ptmaxtracksize.y = 400;
LPMMI-> ptmintracksize.x = 600;
LPMMI-> ptmintracksize.y = 400;
CframeWnd :: ONGETMINMAXINFO (LPMMI);
}
2. Close the dialog and window:
In fact, the destruction of the general window can be destroyed with DestoryWindow (), and the destruction of the dialog box can be enddialiog ().
EndDialog (IDOK);
The return value of Domodal () is IDOK, but does not execute the user-defined Onok.
As long as you send a WM_CLOSE message, there will be a function of responding.
SendMessage (WM_CLOSE);
Postmessage (WM_CLOSE);
Void ctestdialog :: onbutton1 ()
{
GetParent () -> DestroyWindow ();
}
Window and dialog box
Postmessage (WM_QUIT);
SendMessage (wm_quit); //
No mode dialog with destroyWindow ();
EndDialog
You have a problem with you open the original dialog.

C *** App Defines a cstring
when using it
Void cdlgdlg :: onbutton2 ()

method one:
Shellexecute (this-> getsafehwnd (), "open", "f: //he.txt", null, null, sw_shownormal);
Method Two:
Process_information pi;
Startupinfo Si;
Si.cb = sizeof (startupinfo);
si.lpreserved = null;
Si.lpdesktop = null;
Si.lptitle = NULL;
Si.dwflags = 0;
Si.cbreserved2 = 0;
Si.lpreserved2 = NULL;
Bool Bres = CreateProcess (Null, "Test A.TXT B.TXT", NULL, NULL, FALSE,
Normal_Priority_Class,
NULL, NULL, & SI, & PI;
IF (BRES == FALSE)
{
AfxMessageBox ("CreateProcess Failed");
}
Else
{
CloseHandle (Pi.hthread); DWORD dwret = WaitForsingleObject (pi.hprocess, 1000 * 30);
Switch (dwret)
{
Case Wait_Object_0:
DWORD DWEXITCODE;
Bres = getExitcodeProcess (pi.hprocess, & dwexitcode);
TCHAR EXITMSGBUF [1024];
IF (BRES)
{
WSPrintf (Exitmsgbuf, "EXIT CODE:% D", DWEXITCODE);
}
Else
WSPrintf (Exitmsgbuf, "EXIT code failed to return");
AFXMESSAGEBOX (Exitmsgbuf);
Break;
DEFAULT:
AfxMessageBox ("exit for other reason";
