Re: Creating a GUI in CVIEW 18-Sep-01 6:46 18-Sep-01 6:46  Yeah well.. You know what?! That idea.. You can just.. stuff it up.. hmm.. maybe.. Guess it wasn't quite so dumb afterall :P I might just do exactly that!

I have one option of a menu and I need to change the associated bitmap, in modifyMenu it asks me for a pointer to bitmap, but... Should I take care to destroy that bitmap or the menu handles it ? Thanks, Bye ! Braulio Re: CMenu *pBitmap Tomasz Sowinski18-Sep-01 4:44 Tomasz Sowinski 18-Sep-01 4:44  Should I take care to destroy that bitmap or the menu handles it ? You're responsible for destroying the bitmap. However, you should do it until the menu uses this bitmap. If you delete it earlier, you will see garbage in the menu item.

Everything works fine in release mode, but in debug mode, the application hangs upon exiting. If I remove the toolbar everything works okay. If I add just the definition of the toolbar and not the code, it hangs in debug mode. I'm using CToolbarEx to define the toolbar. Any ideal to what could be causing this????? Any thought, comment or assistance would be greatly appreciated. I found the following errors: memory check error at 0x00D45834 = 0x00, should be 0xFD. memory check error at 0x00D45835 = 0x00, should be 0xFD. memory check error at 0x00D45836 = 0x00, should be 0xFD. memory check error at 0x00D45837 = 0x00, should be 0xFD. Could this be anything??? Thank-you Sincerely, RAH Re: Toolbars Tomasz Sowinski18-Sep-01 4:13 Tomasz Sowinski 18-Sep-01 4:13  Ctrl+Break when app hangs and have a look at the call stack. You should be able to see where's the problem.

Worry about code readability - and in this case exiting early wins hands down.

Anyway, you can always try to run a profile batch against your program to know (your VC++ comes with a profiler tool). From the point of view of readability, my opinion is (in accordance with what others have said) that the first version is better: When you finally got to the main part of code all secondary scenarios are ruled out, and that makes it easier to concentrate on a smaller mental model of your problem. That's how my brain works at least. I guess this could make for an interesting discussion subject at the lounge.

How many nanoseconds do you want to save? I think you're wasting your time on totally irrelevant stuff.

In function like this you're checking if file exists. This means you have to call underlying OS, which usually causes context switch. This operation alone takes orders of magnitude longer than time saved with possible 'optimization' after rearranging control flow. As Michael Abrash writes in his "Graphics Programming Black Book": Know when it matters. (identify the portions of your program where peformance matters, and don't waste your time optimizing the rest.

Do you suggest that you'll be loading bitmaps from disk in tight, time-critical loop?

Basically I want the Tab Control to fill the entire window at all times. My Code is as follows CRect size; GetClientRect(&size); int iWndWidth = size.right; int iWndHeight = size.bottom; ::SetWindowPos(m_tabs,0,0,0,iWndWidth-15,iWndHeight-15,SWP_NOMOVE | SWP_NOZORDER); Can anyone tell me why i needed to subtract 15.
