Comdlg32 Fails to Display Drives Mapped by SUBST Command

 Last reviewed: February 16, 1998
Article ID: Q177631
The information in this article applies to:
  • Microsoft Windows NT Workstation version 4.0
  • Microsoft Windows NT Server version 4.0

SYMPTOMS

Drive letters mapped to other network drives by the SUBST command may not show up in the Drives box of a 16-bit Open common dialog box. This happens for all 16-bit programs that use GetOpenFileName() to display the File Open common dialog box.

CAUSE

Internally, there are two threads working together to display the Drives box; the lack of synchronization between those two threads causes the symptom described above.

RESOLUTION

To resolve this problem, obtain the following fix or wait for the next Windows NT service pack.

This fix should have the following time stamp: 

   12/04/97  05:25p               189,712 Comdlg32.dll (Intel)
   12/04/97  06:22p               365,328 Comdlg32.dll (Alpha)

STATUS

Microsoft has confirmed this to be a problem in Windows NT version 4.0. A supported fix is now available, but has not been fully regression tested and should be applied only to systems experiencing this specific problem. Unless you are severely impacted by this specific problem, Microsoft recommends that you wait for the next Service Pack that contains this fix. Contact Microsoft Technical Support for more information.
