The information in this article applies to:

The Microsoft C/C++ Compiler (CL.EXE), included with:

    - Microsoft Visual C++, 32-bit Edition, versions 1.0 and 2.0

SYMPTOMS

Running the StreBlt GDI StretchBlt Win32 application programming interface (API) sample can cause Windows NT to hang.

STATUS

Microsoft has confirmed this to be a problem with Windows NT 3.1. This problem is illustrated by the StreBlt sample supplied with Visual C++ 32- bit Edition. The problem was fixed in Windows NT 3.5.

NOTE: This sample was not included with Visual C++, 32-bit Edition, version 4.0.

MORE INFORMATION

To reproduce the problem, follow these steps:

Build the StreBlt sample using the supplied makefile.
The sample displays a dialog box for the main window. There are three drop-down list controls titled StretchBltMode, Pattern, and Standard ROPs. Select the following in these drop-down lists:
```
      StretchBltMode    BLACKONWHITE
      Pattern           NULL_BRUSH
      Standard ROPs     PATPAINT
```

At this point Windows NT will hang.
