Why are bitmaps displayed in a debug version of a program but not in the release?

Why are bitmaps displayed in a debug version of a program but not in the release?

1. I have an Active X control.
2. It uses AFX_MANAGE_STATE to get hold of the bitmaps from its own resource.
3. The bitmaps are loaded into an image list and displayed in a CListCtrl.
4. The bitmaps are displayed in the debug version of the program
5. The bitmaps are NOT displayed in the release.

Thanks in advance

without source we can only guess - however here as a suggestion

Unintialized variables - debug has a habit of initializing variables to 0 - however in release theses variables could have any value. Make sure all your variables have the values set to what you want them to be don't assume the compiler will.

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

No, it doesn't.  An uninitialized variable is an unintialized variable. If you find one that has any particular value more often than another, you're just lucky.

(Unless you're using the /GZ compiler switch.)

oops I did mean 0xCC which I think is the /GZ option (standard company option for debug here)

Ive got the bitmaps to display, I simply removed the ASSERT statement.

What ASSERT statement? You haven't mentioned any ASSERT statements until now.

The ASSERT was on the CImageList Create function. Prety dumb really. Thanks for everyones help. By the way why did it work in the Debug and not in the Release?

in release ASSERT is define as

#define ASSERT(f)          ((void)0)

which means that 'f' never gets executed

you should have used VERIFY instead which works the same as ASSERT in debug but in release it is defined as

#define VERIFY(f)          ((void)(f))

so 'f' does get executed

PS now you know why we wanted to see the code as this wuld have been spotted straight away (I hope) as it is a common gotcha (sic)
