Hi
Thanks Maxwell.
But I am not using MFC. It is a simple C program.
Also do I need to include any header file to use CString.

Forget about CString stuff, since it is of C++.
For C program, do this way:
//
#include <windows.h>
/* ..... */
/* in your function, for example. */
void FooBar()
{
int iNum = 12345;
char sText[12] = {0};
sprintf(sText, "%d", iNum);
/* Including windows.h is for MessageBox function call. */
MessageBox(NULL, sText, "MyMsg", MB_OK);
}

int iNum = 123;
TCHAR szNumAsString[256]; // arbitrary size
_stprintf(szNumAsString, _T("%d"), iNum);
::MessageBox(NULL, szNumAsString, _T(""), MB_OK);

There is no scope resolution operator :: in C.

Go the Project/Settings menu, then click on C/C++, select 'Precompiled Headers' from the category dropdown, and switch them off.
|
|
|
|
|
don't your problem come from that error ? :
fatal error C1010: unexpected end of file while looking for precompiled header directive
try to place the #include "stdafx.h" before all other includes...
you can also read the FAQ

Sometimes you do have to disable precompiler headers inorder to compile.

I want a true replacement for MFC Sockets due to its bugs and inefficiency , so can anybody refer me a socket library(free or commercial) which has almost same public interface of MFC sockets but efficient that MFC sockets.
I have some existing projects which are running with MFC sockets , so i want such kind of replacement which doesnt change the existing code very much , but certainly should increase the performence.

I've written an ISAPI Filter that tries to grab the Session object(ISessionObject) via the ObjectContext. There are several examples of this in regular(non-ISAPI Filter) DLLs, but non for an ISAPI filter. My code for getting the object context appears ok.
When I attached my ISAPI filter to the inetinfo process and stopped it at a breakpoint, it gave the "There is no MTS object context" error.
Am I trying the impossible? Cna one not get an mts object context in an ISAPI filter?
TIA,
Andy C.
