So does Out have enough room for 2692 characters?

You have to use the good ole fashion "tool blame" to keep a small amount of sanity.
Yes, it is being allocated the proper space. A coworker has suggested that it might be a memory error where something is writing to that chunk and skewing the number?

That's what I've been tring to get at for several posts now, but without having any actual numbers, could not be for sure.

Set a breakpoint on any of the statements within the for loop. Add Channel to the watch window. Go through the for loop using F5. Watch Channel at each iteration. Hopefully you'll see it change to -1.

I appreciate the help, and im glad you havent just gotten fed up with me, but this loop is called per channel per scanline, so its simply not possible to watch Channel on every iteration. Since this error is not repeatable in the same spot every time, im fairly sure that im just screwed. Thank you for all the suggestions.

Have you considered:
for (int Channel = 0; Channel < NumberOfChannels; Channel++)
{
if (-1 == Channel)
;
Dat = (unsigned char*)m_Dither.Dat[Channel];
Out = (unsigned char*)lpDithered->Data[Channel];
ChannelData = &(lpDthrCtrl->Data[Channel]);
...
}

all right! i finally got it! let me explain a little bit more about this problem. im working with my company's legacy code, and im not allowed to change it because "it works."
what im supposed to be doing is writing an interface to this class. so i tracked the problem down, and it was a call to CoTaskMemAlloc(1024)...
why the did they hard code this, and why cant i change it?
so basically what i had to do was cut out the call to that function and manually reset all the memory calls to the proper sizes from the interface.
i imagine this wasnt a problem when they were processing small images, but now they're using huge digital photo quality images, im tempted to tell my boss whats up, but then ill probably hear an ear full for working around their class that "just works."
thanks for the help man.

So exactly how did allocating 1024 bytes, rather than some larger number, mess up what you were doing?

it knew it was supposed to be accessing that memory, but it wasnt allocated properly, so it was overwriting into memory set aside for Channel and LengthInBytes. We (my cube mate, and i) stuck a whole bunch of _Asserts everywhere, and Channel never equaled -1, but as soon as the it set Out = (unsigned char*)lpDithered->Data[Channel]; Channel and LengthInBytes lost their value.

Hi,
I created a win32 dll and I want use InvokeHelper function in it,but when i include that function it is giving error as "Undeclared Identifier",
So I tried to include it's header file AFXWIN.H,but it is not taking in it.
What i need to do to use InvokeHelper function???
Please help me with your suggestions,
Thank you

What's your context?
The docs say that InvokeHelper is part of the COleDispatchDriver and CWnd classes, thus when you call InvokeHelper() you're really calling ::InvokeHelper(), which doesn't exist in the global namespace.

You are still very much unclear. Do you mean to say that the edit control never receives focus when you navigate through controls with the tab key?

I think I get your question now. Have you set the tab order in design time?
Layout menu->Tab Order

How you are invoking that dialog bat ? Just test by using ctrl + T in resource editor(that will invoke dialog bar). And then use tab.
I just made a simple(Hello world) win32 application using VS2005. And insert dialog bar as resource, added two edit boxes, with tab stop property set to true. And tested that using Ctrl + T. It works fine for me.

Can you please provide me your link ?
If possible , please Resource is very important.
I am working in vs2005 same but
One thing I want to ask you which one is you have used when you insert your dialog.
There are two option after right click.
1)Add resource
2)Insert Dialog
I had use first one then click on "+" sign and use first "IDD_DIALOGBAR".
I had stretch it make it propersize remove "TODO:layout dialog bar" put 8 edit box controls setting tab order 1 to 8 and set property true when run the application and hit Tab key the "Beep" come.

movement in edit control.
