Display a MessageBox right after a dialog is drawn on the screen?

[usfesco]

hi all, I would like my dialog-based app to pop up a message box right after the dialog itself is shown on the screen... anyone knows how to do that? If I put a message box in my dialog's OnInitDialog like this: BOOL CTestDlg::OnInitDialog() { CDialog::OnInitDialog(); ...... AfxMessageBox("hello"); return TRUE; // return TRUE unless you set the focus to a control } the message box pops up before the main dialog appears, but I want the message box to pop up AFTER the main dialog appears. I've tried handling WM_SHOWWINDOW message, i.e., put the AfxMessageBox in the dialog's OnShowWindow() function, but it was the same thing as putting the AfxMessageBox in OnInitDialog() -- the message box still pops up before the main dialog appears. Thanks for your help in advance :-O

The easist way is post a custom message to your dialog from the OnInitDialog function, that way OnInitDialog will close, and the dialog will be created before the message is handled. In the custom message handler you call AfxMessageBox.

#define WMU_POPUPMESSAGEBOX WM_APP;
...
BEGIN_MESSAGE_MAP(CTestDlg, CDialog)
...
ON_MESSAGE(WMU_POPUPMESSAGEBOX, OnPopupMessageBox)
END_MESSAGE_MAP()
...
BOOL CTestDlg::OnInitDialog()
{
...
PostMessage(WMU_POPUPMESSAGEBOX, 0, 0);
return TRUE;
}

HRESULT OnPopupMessageBox(WPARAM, LPARAM)
{
AfxMessageBox(_T("Hello"));
return 0;
}

Hey, i used the following technique in my program to solve a same problem. when you recieve WM_INITDIALOG message, call ShowWindow(hDlg,SW_SHOW); //plese write the MFC equivalent urself;P) After that, you can call MessageBox to do your stuff... That's simpler solution.
