The Unexpected QuickWin Error

Q112389

The information in this article applies to:

Microsoft Windows Software Development Kit (SDK) 3.1

SUMMARY

Applications for Microsoft Windows developed with the Windows SDK may display an error message box with the error:

"Unexpected QuickWin Error"

MORE INFORMATION

There are several possible causes for this error:

A QuickWin application caused an unexpected application error (UAE) or general protect (GP) fault.

A Microsoft Windows-based application that is not a QuickWin application called a QuickWin function. If execution of a non-QuickWin application for Windows results in this error, one of the QuickWin functions was linked and executed in the application.

Possible mismatch of memory model libraries (for example, building a large model application but using SLIBCEW, the small model library for Windows.)

Possible stray function pointers that accidentally call one of the QuickWin stubs.

You may have attempted to use an invalid file handle with one of the I/O functions.

The run-time libraries for Windows (SLIBCEW, MLIBCEW, CLIBCEW, and LLIBCEW) contain stubs to the QuickWin functions. Therefore, the linker will not give an error when linking with a QuickWin function from a non-QuickWin application for Windows. However, when the function executes, an error message box with the error "Unexpected QuickWin Error" will be displayed.

The following functions are in the QuickWin library:


   _fwopen                    _wgopen
   _inchar                    _wgsetactive
   _wabout                    _wmenuclick
   _wclose                    _wopen
   _wgclose                   _wsetexit
   _wgetexit                  _wsetfocus
   _wgetfocus                 _wsetscreenbuf
   _wgetscreenbuf             _wsetsize
   _wgetsize                  _wyield
   _wggetactive
