When an MFC project program is created, testing a dialog box may end
Visual Studio
R
in error. (For distinguishing MFC projects, refer to "Appendix

This problem occurs if an ACT control is added on a form and then "Test
Dialog" is performed in an MFC project when DEP is enabled to ACT
controls.
The following shows the cases that DEP is enabled.

Other than AlwaysOn
(When AlwaysOn:
Change to OptIn,
When other than AlwaysOn:
No change necessary)
When the DEP configuration cannot be changed, this problem can be
avoided by creating a program using an ACT control without pasting it to a
form (Reference).
