A in house program not work on WIN7 unless DEP is completely turned off.

We have a in-house program written by Visual Studio 2005 VB6 and being compiled in a Windows XP platform. The program has been working fine on the XP environment until when run it on a WIN7 Platform, it shows error message "unable to get the window handle for the "AxVSFlexGrid' control. Windowless ActiveX controls are not supported".

After doing some research, we have found a command "bcdedit.exe /set {current} nx AlwaysOff " to turn DEP off and it works in WIN7.

We have tried to turn off that particular exe file from the exception list from the WIN7 DEP but getting a message "This program must run with data execution protection (DEP) enabled. You cannot turn off DEP for this program. "

We do not have this issue or need to turn off anything in Windows XP.

Experts, please advise if you have any clue.

Many Thanks.

Sorry. I have read that article. None of those.

The program was compiled in a XP platform.

Ok, then the application has been detected doing bad things executing from memory. Have you updated to the latest release of FlexGrid? A quick search showed me there were problems with older versions and DEP

Tomasp, would you explain? What is the fix of the older version of DEP?
