DirSelectPopup causing GPF

[Vishi Anand]

I have installed CVI6.0 and CVI7.0 on same PC (using windows XP). Now my
CVI6.0 programs give general protection fault on DirSelectPopup
function. Please help. I need to support both versions.

Vishi,

I have not been able to find any reports on this function generating a GPF. I have CVI 7 and 6 in my computed and I can use the function with no problem.

Make sure that the string where you store the path hase at least MAX_PATHNAME_LEN elements; since this is a very strait forward call to the Windows SDK not passing enough memory would cause a GPF in release mode.

Please give me more details to replicate this problem here and work on it.

Regards,

I will post the code tomorrow, it is on my laptop. The same EXE works
fine on a machine which has the 6.0 RTE installed, but causes GPF on my
development machine.
