CDialog::DoModal() Hangs

[pallavi pathak]

Hi,

I have created a dialogbox "Certdlg". which I am trying to display

if(certDlg.DoModal() == IDOK)
{
valid = 1
}

but this call goes and hangs in CDialog::DoModal(); . I could realise the problem it have is the "Hwnd" , am passing while invoking dlg constructor.

CISCertDlg certDlg(thumbPrint, validFrom, validUntil, parentWnd);

Passing Null, in parentWnd, creates dlg but with no handle to application.

In place of certdlg if MessageboxEx is called then also DoModal hangs while calling messagebox.

Suggest you try this:

// In the caller:
CISCertDlg dlg;
dlg.thumbprint=.. // or however you are setting your dialog variables.
dlg.validFrom=..
etc
int result=dlg.DoModal();

// In the dialog class, use the default constructor, which has no arguments.

If this works, you can try constructors with arguments. Since the parent window's handle is a default argument, you can determine what it should be, if you still want to have a constructor as you show.
