Thread: Dialog Edit box v's WindowsText Problem

I have a dialog box containing 2 editbox's. I want to use the following function to save these 2 editbox's to 2 separate files.

I have tried adding varios Dlg funtions to make it work, but nothing seems to happen.

I found the following function in an example for a basic text editor. Can anyone suggest how I change this funtion to do the same for an editbox in a Dialog:

Code:

BOOL SaveFile(HWND hEdit, LPSTR pszFileName)
{
   HANDLE hFile;
   BOOL bSuccess = FALSE;

   hFile = CreateFile(pszFileName, GENERIC_WRITE, 0, 0,
      CREATE_ALWAYS, FILE_ATTRIBUTE_NORMAL, 0);
   if(hFile != INVALID_HANDLE_VALUE)
   {
      DWORD dwTextLength;
      dwTextLength = GetWindowTextLength(hEdit);
      if(dwTextLength > 0)// No need to bother if there's no text.
      {
         LPSTR pszText;
         pszText = (LPSTR)GlobalAlloc(GPTR, dwTextLength + 1);
         if(pszText != NULL)
         {
            if(GetWindowText(hEdit, pszText, dwTextLength + 1))
            {
               DWORD dwWritten;
               if(WriteFile(hFile, pszText, dwTextLength, &dwWritten, NULL))
                  bSuccess = TRUE;
            }
            GlobalFree(pszText);
         }
      }
      CloseHandle(hFile);
   }
   return bSuccess;
}

I apreciate the help...this is doing my head in!!

Thanks!

I tried that and got an error when trying to compile about the HWND not being right.

I think I'm calling it wrong or something. I have it in a WM_COMMAND switch:

Code:

switch (LOWORD(wParam)) 
{
	case IDSAVE:

		HWND hTempPre;
		hTempPre = GetDlgItem(hwndDlg,IDPRE);

		SaveFile(hTempPre, "pre.bat");

		HWND hTempPost;
		hTempPost = GetDlgItem(hwndDlg,IDPROST);

		SaveFile(hTempPost, "post.bat");
		return 1;
	case IDCANCEL:
		return 1;
	case IDCLOSE:
		EndDialog(hwndDlg,0);
		return 1;
}
break;

I also tried it like:

Code:

	case IDSAVE:


		SaveFile(GetDlgItem(hwndDlg,IDPRE), "pre.bat");


		SaveFile(GetDlgItem(hwndDlg,IDPROST), "post.bat");
		return 1;

but that just does nothing....any ideas?

Thanks again!
