How to fix VB6 crash while Writing EXE

Author	Message
Philip Hot #1 / 2	How to fix VB6 crash while Writing EXE I recently ran into a problem where the VB5 SP5 IDE crashes while Writing the .EXE file. That's after successfully finishing the compile on an application that works perfectly when run inside the IDE. It's not running out of memory or disk space resources, and happens on a variety of machines running either NT4 SP5 or Win2K SP2. Every time VB6 crashes with a Application Error that "The memory could not be "written"." In searching the newsgroups I found other people had hit this problem, but no solution was posted, but I eventually found the answer in a VB FAQ (Section 12.1). In the IDE, arrays are dynamic by default. When compiled, arrays are static by default. According to the FAQ this changes where the arrays are stored (DGROUP instead of heap). Apparently, VB6 SP5 still has problems that have been around for a very long time in how it handles static arrays. To fix it, you need to put the comment: 'DYNAMIC as the first line the .frm source. You could also manually use dynamic arrays and ReDim, but this is a quicker change for existing code. That forces all arrays to be dynamic, even when compiled. It fixed the problem for me. Good luck.

Alex #2 / 2	How to fix VB6 crash while Writing EXE Just wanted to clarify something. The subject says "how to fix VB6 crash...." but in your message you say you ran into the problem using VB5. I remember writing a program ages ago with vb5 and I had basically finished it when I tried to compile and vb crashed. I wish I had had this solution at the time. Also another thing, so you add the comment to every form? Or every form with dynamic arrays? And do you need to add the comment in the general declarations sectio before all the code or do you need to open the .frm file in Notepad and add it there somewhere?
