I want to fill an edit control from a text file. I need help debugging
a couple of runtime errors: "Stack around the variable txtFromFile was
corrupted" and an access violation in ReadFile(). Ideas?

   char szFileName[MAX_PATH] = "";

   DWORD bytestoread = 1024;
   DWORD bytesread;

   if (LOWORD(wParam) == ID_BROWSE)
   {
       OPENFILENAME ofn;
       ZeroMemory(&ofn, sizeof(ofn));

       ofn.lStructSize = sizeof(ofn);
       ofn.hwndOwner = hDlg;

OFN_HIDEREADONLY;
       ofn.lpstrDefExt = "txt";

       if (GetOpenFileName(&ofn))
       {
           HANDLE hFile = CreateFile(szFileName, GENERIC_READ, 0,
NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL);

           if (ReadFile(hFile, &txtFromFile, bytestoread, &bytesread,
NULL))
           {
               SetDlgItemText(hDlg, IDC_EDIT1, txtFromFile);
           }

           CloseHandle(hFile);

           return true;
       }
   }
