Hello Ian,
thanks for answer.
I don't know how to do this, if yes, i will never ask something here, the time is to expensive for that!
You know that, when you make a right mouse click on a folder or file in explorer, its open a menu, and one of choices is "Send to archive" (or similar, sorry about my english),
that is what i mean!!
If this don't work, i know here is a Zip Utils that i can use, but i like to try this first!
I can only show my try, its like this:
DWORD dwFileMask;
long mask;
dwFileMask = GetFileAttributes(csCurFolder);
mask = dwFileMask;
if(!(dwFileMask & FILE_ATTRIBUTE_ARCHIVE))
{
mask = dwFileMask | FILE_ATTRIBUTE_ARCHIVE;
SetFileAttributes(csCurFolder, mask);
}
but thanks for your help

The archive attribute for a folder is used by backup programs - it's not the same thing as a zip file.
There are zip library articles here on CP. I don't know a specific one to recommend, but CP is searchable. Once you've read several, you will know more than me about them.
1/ So, make the files you want. Put them somewhere temporary.
2/ Make a zip file containing those files. <-- this is the hard bit, but look at CP articles.
3/ Delete the original temporary files.
The right-click thing in explorer is a context menu extension, and just does step 2 above.
Good luck,
Iain.

Hi Guys,
I am having an issue with vsnrpintf() function.
My function posts an error message by formatting it using vsnprintf()
Ex:
void SetErrorInfo(const CHAR* lpzformat, ...)
{
va_list();
va_start(vargs,lpzformat);
_vsntprintf(szbuf,MAX_PATH,lpzformat,vargs);
}
This is crashing when i dont have arguments passed to this function and the formatted string has "%n" or "%s" which are known place holders for BufferOverflow.
Can anyone let me know if i can get a count of vargs argument list and based on that decide whether to use
vsnprintf() or not?

This is a side effect of variable argument functions like printf(). You can have more arguments than % in the formatting string, but not vice versa.

Hi,
That is very much true, but cant we have a check on the arguments, as in if there are no arguments and the formatted string has %n or %s, then instead of vsprintf() simple sprintf(buf,"%s",lpsformat); can be called.
Atleast that solves the problem.
But i am not able to find the count for no of arguments.

I think it is not posible to avoid such error in generally.
Because we cannot detect argument count for function(format, ...) at execution time.
Uncertain ideas here.
1. Always pass some constant which has reserved pattern which indecates the last arg.
2. Use try-catch block defined in c++.
3. Use SEH (__try-__catch) defined by MS.
4. Abandon f(a,...) style function.

Even if you count them yourself, so what? You still can't pass, say, a 1 for a %s parameter and not have it fail.
I have a safe format function which is basically the following (with more error and exception processing, but this gives the gist):
__try
{
return _vsnprintf(pBuffer, bufferLen, pFormat, args);
}
__except (EXCEPTION_EXECUTE_HANDLER)
{
Copies raw format string into buffer
}

You say that this is YOUR function to post an error message, thus it is assumed that it is YOUR code that is calling this function. I would suggest that you examine all calls to SetErrorInfo in YOUR code to insure that they supply parameters for each '%' in the format string.
There is not a built in way to check the number of arguments pushed on the stack for a call.
There is a messy way to do this, but it involves modifying all code that calls SetErrorInfo, and this amounts to the same effort (only more so) as to examine all the calls to SetErrorInfo. You could drop into ASM and push a flag value (__ASM mov eax,0x012345678 __ASM push eax) just before making the call to SetErrorInfo, make the call, then erase the flag upon return by dropping into ASM again (__ASM add esp,4). Inside SetErrorInfo you could examine the stack by dropping into ASM and check if the flag value immediately followed the format or was found too close to the format argument for the number of '%' characters in the format string. First you have to verify that a format string has actually been passed (and not a NULL argument), then that the string contains % characters, etc, etc, etc. Messy, messy, messy! Just examine all calls to SetErrorInfo.
Dave.

CSting strid = m_strStringArr.getat(i);
T("INSERT INTO tablename (setid) VALUES('strAnsi')");
This is my query and i get table field and its value at runtime.So how to insert this value.any idea about it..means Setid and stransi i get at runtime..

Use CString::Format[^] to create the string.
CString cs;
cs.Format(_T("INSERT INTO tablename (%s) VALUES('%s')"), setid, strAnsi);

But after set this data to fields,every fields ti goes into new line.i dont want this.I want after new line it goes to next line or next record.So how to solve this problem..

When strAnsi has _T("aaa\nbbb\nccc") then want to make 3 records?
Do you mean like this?
If then, you must split strAnsi at first and make and execute sql 3 times.
For example;
TCHAR* strData = strAnsi.GetBuffer(-1);
TCHAR* pToken = _tcstok(strAnsi, _T("\n"));
while (pToken) {
CString sql;
sql.Format(_T("INSERT INTO tablename (%s) VALUES('%s')"), setid, pToken);
}
strAnsi.ReleaseBuffer();
Well, I dont feel good VALUES('%s') in above sql because of string
escaping issue or SQL-injection problems.
I usually use prepared statements or parameterized query for this purpose.

Do you really  mean this
CString strTable = _T("MyRuntimeValueForTable");
CString strData = _T("MyRuntimeValueForData");
CString strQuery;
strQuery.Format(_T("INSERT INTO %s VALUES ('%s')"), strTable, strData);
?

No, useless.
Simply use built-in Win32 XML apis (COM, SAX, and others)
Tons of samples in MSDN in C and C++
