SYMPTOMS
When you run identical C and Visual Basic (VB) CPIC applications, the C
application works correctly but the VB application fails on cmalloc() with
the following error:
return code 20: cm_product_specific_error
CAUSE
The SNA Server Windows 3.x client software incorrectly parses the CPIC
application program name, so its associated transaction program entries in
the WIN.INI file (such as the LocalLU parameter) are not found.
For example, if your application name is WIN-UP.EXE, under C it is known as
WIN-UP. The VB application sees this as WIN-UP.EXE. If you are not pooling
Local LUs as per
132720 (SNA Server CPIC Allocate Error 20) the above
error appears, even if you have defined the following in the WIN.INI file
of the client computer:
[WIN_UP]
APPCLLU=<LOCALLU>
RESOLUTION
To correct this problem:
- Contact Microsoft Product Support for an update to SNA Server 2.11 and
WINCPIC.DLL library.
-OR-
- Enable pooling. For additional information, please see the following
article(s) in the Microsoft Knowledge Base:
