I found an issue for a hang of 16-bit application
(www.formdocs.com) installer.
The app registers with NotifyRegister16 callback
function and looks like it hangs while
waiting for completion of child process. The last part
of relay trace is attached.
NotifyRegister16 function of ToolHelp dll is used to
register handler for following events:
NFY_UNKNOWN
NFY_LOADSEG
NFY_FREESEG
NFY_STARTDLL
NFY_STARTTASK
NFY_EXITTASK
NFY_DELMODULE
NFY_RIP
NFY_TASKIN
NFY_TASKOUT
NFY_INCHAR
NFY_OUTSTRING
NFY_LOGERROR
NFY_LOGPARAMERROR
Note, this works for 16-bit applications only.
These events also used by debuggers to debug 16-bit
applications.
Can somebody give me a hint how is better to approach
implementation of
NFY_EXITTASK, NFY_STARTTASK events generation?
How important do you think is to implement this
functionality, since it is for 16-bit apps only?
