Question
ProUIDialogCreate first time return 0 but second time return -1 ?
I got a problem about created dialog, the steps create -> activate -> exit -> destroy worked fine at first but second time failed.
creo 2.0 M230
win7 x64
first, dialog shows normally


after close dialog then click button again, dialog doesn't show up

this discussion describes the same situation but the solution doesn't work for me.
Solved: OTK C++ - Creation of Dialog fails the second time - PTC Community
