Also, you're assuming the size of a character is 1 byte (which is true for non Unicode/MBCS systems).
AFAIK a char in C/C++ is always one byte in size. And his example uses chars not TCHARs.

Good point! 
I've been spending (way) too much time moving between CStrings, char* and XMLCh in my (Unicode) app. My mind is in a fog (i.e. more than usual).

Perfectly understandable. I don't remember the last time I used char in an MFC app. It's practically extinct.

Not the way you have them. Here's how:
char MyBuffer[10];
// 1
MyBuffer[5] = 'x';
// 2
char* pMyBuffer = MyBuffer;
pMyBuffer = pMyBuffer + 5;
*pMyBuffer = 'x';

How can I use the Setup API functions with a INF_STYLE_OLDNT inf file to cause the PnP Manager to kick in? If I need to use a INF_STYLE_WIN4 inf file, what are the key Setup API functions?

I have a static filter using something like this:
TCHAR* tcFilter = _T("Word Document\0*.DOC\0Excel Document\0*.XLS\0");
What I really need is a dynamic filter where I can remove or add file types to it.
TCHAR* tcFilter = NULL;
if (IsWordInstalled())
etc.
Any suggestions on how I can do this? That '\0' delimiter really throws me for a loop.

I think you'll need to use std::string to handle the embedded '\0' characters.
Otherwise, you'll have to get tricky with the memcpy() function.

Correct.
One solution is memcpy().

This works for me:
CString strFilter;
strFilter += ...
strFilter += (TCHAR)'\0';
dlgFile.m_ofn.lpstrFilter = strFilter;

Would that handle multiple filters separated by '\0'?

Yes. You only need the \0\0 at the end from memory. Anyway this is how I do it in ED (see sig) to dynamically build the file types list.

How about a little function that you can call for that:
int AddToFilter(TCHAR* szFilter, int nSize, LPCTSTR szDescription, LPCTSTR szExtension)
{
ASSERT(szFilter);
ASSERT(szDescription);
ASSERT(szExtension);
_tcscpy(&szFilter[nSize], szDescription);
int nLenDesc = _tcslen(szDescription);
_tcscpy(&szFilter[nSize + nLenDesc + sizeof(TCHAR)], szExtension);
int nLenExt = _tcslen(szExtension);
return nSize + nLenDesc + nLenExt + (sizeof(TCHAR) * 2);
}
Then you can use it like this:
TCHAR szFilter[300] = _T("");
int nSize = 0;
if (IsWordInstalled())
nSize = AddToFilter(szFilter, nSize, _T("Word"), _T("*.doc"));
if (IsExcelInstalled())
nSize = AddToFilter(szFilter, nSize, _T("Excel"), _T("*.xls"));
AddToFilter(szFilter, nSize, _T("All Files"), _T("*.*"));
I haven't tested (or even compiled) this, but hopefully it's close enough.

Whoa, thanks. I didn't expect you to write the code for me, but I'll give it a shot.

I would say you must do this dynamically with raw tchar data - and you must terminate it with \0\0 BTW. Make sure tcFilter is declared with space to spare, find the length by searching for "\0\0",

Hi all,
I am developing a dialog based application in VC6.0
I have four bitmap resources on main dialog window.
I have disabled them on startup by calling ShowWindow(FALSE) and enabling them on runtime, by calling ShowWindow(TRUE)
They are appearing in a sequence because I have enabled them one by one.
I want to enable them all parallel rather then in sequential manner.
Please any body knows how to do that.
Regards,
The Phantom.

i'm using visual c++.net and sometimes when i'm just typing in code, the whole C++ development environment just crashes. A DOS command box appears onscreen with the word 'mscordump' on it... and the development environment just closes itself. This is very strange - does anyone know what could cause this?

Processor overheating?
Memory-timing too fast for your (possibly crappy) ram-chips?
Bad sectors on your harddisk in some essential DLLs or your Pagefile?
Who is 'General Failure'? And why is he reading my harddisk?!?

Dear All,
I am developing an application in MFC VC++ Version 6.0 on Windows 2000.
Please help me out in following problem:
I have deleted a folder and the folder is moved to recycle bin. I get the exact path of the
recycled folder from my application.
For example
If i delete a folder say "myfolder" from c:\
c:\myfolder
I get the string path
C:\RECYCLER\S-1-5-21-1844237615-1202660629-1060284298-500\dc1
corresponding to it.
Now i have the path of the recycled folder. From this string I need to know the the original
location of the folder from which it was deleted.
I went through the article given in
http://www.codeproject.com/shell/recyclebin.asp
This article is very nice but unfortunately i couldnot get any useful hint from this article to
solve my purpose.
Can anybody please suggest a way out to get the original location of the deleted folder?
I hope my question is clear, please let me know if anybody needs further clarifications.
Thanks in advance,
Best Wishes,
Rohit
