I believe the one or more of the loops try to access and/or modify an index that is out of bound. Recheck all loops.
Do you do some math using on the integer used to access the array, i.e. int i = something * something1 - something2?

Weird. The case of order of declaration is weird. As an experiment, declare both arrays as global. Test your loops.

I'm guessing that you are going out of bounds on the end of one of the arrays. When strange problems start to have "solutions" like moving variables around, and you are using arrays, ALWAYS make sure you aren't going out of bounds on the array.
From the clues you've given, I'm betting 90% that you are going out of bounds on the used_nodes array. When you go out of bounds on it, if you have it before the instructions array, you are simply stomping on the instructions array. If you swap the order of declaration, you are modifying whatever variable comes next in your class. Or, if your class doesn't have any more members, you are modifying somebody else's data.

Thanks guys,
I guess i'll have it to look thru it again, from what i recall, most of my arrays are called from a fixed for loop so i don't know how there could be data going out of bounds. Although, i can see data being changed in an array while debugging, but i dont know where it came from. Is there any possibility of finding out what causes the change of value of a variable from the debugger, i.e. which line of code?
Cheers.

It's possible to set "Data" breakpoints with VC6. Try to look it up in the MSDN (I'm not on my Dev Machine or I would). It's a little tricky, but it will definately do what you want. What it basically allows you to do, is have a breakpoint hit when some code stomps off the end of the array. If you want some more info, I'll post more tomorrow when I'm back on my dev machine.

Does anyone know if there are any c++ examples of parsing date/time from rfc822/1123 email message headers on the net?
(I've done much hunting for this but can't seem to find an actual snippet or source and I don't want to re-invent the wheel)

all u need is a regular expression engine or even a simple tokenizer class will do the job do u have either of those?

No I don't, but I know that's how it's done in the perl world etc.
I was hoping to avoid all that and find a function in straight c or c++; the problem is that there are variants of the way that date is presented according to the docs I've been reading and it's not uncommon for an algorithm to handle that to have some "finagling" built into it, so rather than re-inventing the wheel...

u don't have a simple string tokenizer class? how the heck do you get anything done?

Search for getdate.y. It's an RFC compliant parser written in Yacc. Generate C-code by running bison on it.

Ok here's the code
hdrop = (HDROP) ::GlobalLock ( hg );
if ( NULL == hdrop )
{
::GlobalUnlock ( hg );
return;
}
uNumFiles = ::DragQueryFile ( hdrop, -1, NULL, 0 );
for ( UINT uFile = 0; uFile < uNumFiles; uFile++ )
{
// Get the next filename from the HDROP info.
if ( DragQueryFile ( hdrop, uFile, szNextFile, MAX_PATH ) > 0 )
{
// get the orginal filename and determine if the the extension is upper case or
// lowercase.
origfile = szNextFile;
origfile.Delete(0,(origfile.GetLength() - 4));
BOOL isUpper = ::isupper(origfile[1]);
// Now do the rest.
if ( file.Open( szNextFile, CFile::modeRead) ){
CFileFind fileFind;
if ( fileFind.FindFile ( (path + _T("\\") + file.GetFileTitle() ),0) ){
CString temp = file.GetFileTitle();
makes sense right? get access to the clip board, get the file list from the clip board and loop through the file list, getting the file. My problem is that the file.Open function returns a file name that is all Capital letters when getting the information from a media drive (read CDROM). So if a file is lowercase it the file.Open will automatically convert the filename to uppercase. 
This is unacceptable becuase now the file that I copy over is no longer the same file 
Any ideas

Filenames are not case-sensitive in Windows, so if you're relying on a particular case, then your code is incorrect.
But to answer your question, the filename is all uppercase because that's how ISO9660 stores names (it has a limited set of allowable characters). It would be the same if the source partition were FAT16.

Mike,
Thanks for the prompt reply. That makes sense. My problem is that people are complaining that when they copy stuff from the CDROM to somewhere else, the filename changes from say lowercase to upper case. Unfortuately I have to come up with a solution. Do you have any suggestions?
I'm not dependent on the "case" of the file name, but the inconsistancy is getting me in trouble 
Thanks alot. Starting to make sense now.

Could you get the drive letter from the file name and then query the drive type (GetDriveType)?
Tim Smith
I'm going to patent thought. I have yet to see any prior art.

Yes, absolutely. But I already have the drive letter and information in hand except if its a media device (easy to get though).
As Mike said, it's the way the character information is being stored, so when I grab the file, it kicks back an all uppercase filename. ugh. not sure how to deal with it.

>> not sure how to deal with it
change the interface to make the user supply the target filename using a SaveAs Dialog, u know the same way IE does when you download a file?

is this possible? i see nothing in the MSDN about it, there's no "owner-drawn" style checkbox on the scroll bar property page, and i see no articles here or on codeguru about it.
i want a sexy little scroll bar..., not the boring old everyday ones.

Well I'm sure I've seen OD scroll bars, but where... Have you looked on CodeGuru. Doesn't the WinXP Theme stuff let you control the look of any and every control. I don't know whether GUIgui at http://www.nopcode.com[^] mucks with scroll bars, but it is worth a look.

I have seen them, but I am not sure if they were ownerdrawn scrollbars or custom controls. If I were to try this, I would take a look at the GetScrollBarInfo() (SDK or MFC links) function, it looks promising as it returns the scrollbar's coordinates, thumb size and position, and the state of the various scrollbar components. Maybe call this function in your scrollbar's WM_PAINT handler.

Why the GetBuffer?
str2.Format(_T("item %d: %s\r\n"), i, str.GetBuffer(0));
afxDump << str2;
Looks like just a str would be enough instead of str.GetBuffer? The (0) is also puzzling me.
Thanks
Appreciate your help,

%s wants a const char * (a LPCSTR, in Windows lingo), so the following should suffice:
str2.Format(_T("item %d: %s\r\n"), i, (LPCTSTR)str);
GetBuffer is IMHO overkill for two reasons:- It returns a
char * when just a const char * is needed. - It requires a later call to
ReleaseBuffer, which is prone to error (for lack of care by the programmer, or in the presence of exceptions).

I totally agree with Joaquin. I see GetBuffer abused all over the place, even by Microsoft people.
