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:
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: 132720 SNA Server CPIC Allocate Error 20 (CM_PRODUCT_SPECIFIC_ERROR)
