vb6 crash on exit
I have a legacy vb6 app that crashes on exit - both as an executable and in the IDE. I am currently unloading the forms (except the frmmain) in form_unload, releasing all the adodb recordsets, setting all the boundcollections = nothing, I have attempted to SetErrorMode SEM_NOGPFAULTERRORBOX in the form_terminate event and that has not stopped the error from occurring. I have also checked for subclasses being instantiated in my code and found none. I have checked into the components from outside MS that are used - they are the Componentone flexgrid 8 spelling 8 and componentOne sizer control. An extensive web and forum search has not turned up any known problems similar to mine for these controls. The issue does not seem to occur if I shut down the program before actually doing anything. However loading the bound controls seems to be near where the problem is rooted, in spite of repeatedly stepping with the debugger it seems that the start of the problem "moves around". The problem occurs with the programmatic exit, the "X" and the IDE "end" control
The error message is
The instruction at "0x77d042b8" referenced memory at "0x055c9028". The memory could not be "Read". The title in the error box is a tool tip (differing at different times) from inside my app
