Errata for Steal This Code!

Here are some known issues with the code for Steal This Code:

1. DLL32.C works fine for Borland C++ and for many Microsoft DLLs (including all the DLLs in the book). The issue you may have with Microsoft C++ and DLL32.C is that, by default, Microsoft causes each user of the DLL to have private data. The static variable in DLL32 is reproduced for each user! Therefore, the count is 0 every time it is loaded and unloaded. Each time a new process loads the DLL, DLL32 calls LibMain and each time a process exits it calls WEP. Since the data is private, this probably works out just fine. If your DLL does something that must absolutely only be done once at the beginning or end, you need to share the counter.

2. Please note that the CoolWorx demo ZIP file only works for Win16. It will run under Windows 95 as a 16-bit program, but the install program won't run because the version number is 4. Click here to get an updated installer(about 29K).
3. On a similar note, CoolWorx may have dependencies with specific versions of the compilers you use. CoolWorx was tested with Borland C++ 4.0 and Microsoft Visual C++ 1.5. Other versions may or may not work correctly. This is a common problem with development tools and compilers.
4. A few readers have reported problems with COOLGEN in the demo ZIP file. I haven't been able to reproduce this. COOLGEN writes starter applications - you can use COOLWORX without it (although it is certainly nice to have). I'll post any more information I get about this here.
