c++ cli - Debug Assertion Failed with rgbConverted.cpp -
first saying, it's duplicate question, not same problem.
when run code, message showing, no error.

actually known problem. have solved topics. in code had created text files, docx files , images in c drives. there no permission accessing c drive in computer. had solved following steps:
if can access cmd, can reset security settings in vista/windows 7 following command: "secedit /configure /cfg %windir%\inf\defltbase.inf /db defltbase.sdb /verbose" (no quotes.) see command does, go here: how restore security settings default settings?
note: if can't access cmd when logged in, use guide system recovery options. can command line when access system recovery options screen.
this command seems give ownership issue kick backside, though seems nothing has changed. go explorer, right click on c: , go properties.
go security tab , advanced.
go owner tab. should able click edit.
if don't have administrators in list under says "change owner to:" go "other users or groups". if do, go straight step 7.
on others users or groups type in "administrators" (no quotes) in bottom box. click check name , ok.
click administrators , ok. you've given ownership of c:! (as long account administrator, is.)
click ok on "advanced security settings..." window properties window. should have list of permissions , on before had how couldn't view permissions. progress, eh?
you may need add in adminstrators group edit permissions. this, click "edit" , "add" , type "administrators" (no quotes) in bottom box. hit check name , ok.
click administrators in list , tick box in allow column next "full control".
click apply, you'll bunch of error messages how can't applied files , folders. ok through them all. once done, should have access c: drive once more!
