PRB: FindText, ReplaceText Hook Function

• Microsoft Windows Software Development Kit (SDK) versions 3.1
• Microsoft Win32 Application Programming Interface (API) included with:

      - Microsoft Windows NT versions 3.5 and 3.51
      - Microsoft Windows 95 version 4.0
  

SYMPTOMS

When adding a hook function to the FindText and/or ReplaceText common dialog box, the dialog box is not shown. However, the hook function is receiving messages and the dialog box window does exist.

CAUSE

The hook function is returning FALSE after processing the WM_INITDIALOG message.

RESOLUTION

After processing the WM_INITDIALOG message in the hook function, return TRUE. If your hook function is setting the focus to a specific control, and therefore should return FALSE, add the following code:

   case WM_INITDIALOG:

      ...WM_INITDIALOG code...

      SetFocus(hCtrl);
      ShowWindow(hDlg, SW_NORMAL);
      UpdateWindow(hDlg);
      return(FALSE);
