Put #include "stdafx.h" at the top of the .cpp file that causes the error.

hi,
yes ..it is already in the top of the .Cpp file.But the Problem is appearing yet.
------This is the header file :------------------
// rtcsample.h : main header file for the RTCSAMPLE application
//
#if _MSC_VER > 1000
#pragma once
#endif // _MSC_VER > 1000
#ifndef __AFXWIN_H__
#error include 'stdafx.h' before including this file for PCH
#endif
#include "resource.h" // main symbols
class CRtcsampleApp : public CWinApp
{
public:
CRtcsampleApp();
public:
virtual BOOL InitInstance();
};
This the .Cpp file-------------------------------------------
// rtcsample.cpp : Defines the entry point for the application.
include "stdafx.h"
// WinMain
//
int APIENTRY WinMain(HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPSTR lpCmdLine,
int nCmdShow)
{
HRESULT hr;
UNREFERENCED_PAR
//extra code here
}
Can you tell me how to correct it?
OR
Is there a Problem in "stdafx.h" File?

Hello there,
I have been tracing a C++ code and I encountered a declaration statement like this:
const vector<int>& vars
Can anyone teach me what this is and how it is used?  I tried searching for references on this and I was not able to find any.
Thanks so much!

This is a reference to a constant template vector class that has been specialised with int as its template parameter, ie. it's a reference to a constant variable-length array of ints.

I see... could you give me an example on how to use this? or even a link to a reference will do. Sorry I really don't have an idea of this yet. I don't even know what a template in C++ is.
Thanks!

I don't know of any tutorials off the top of my head. I recommend you get a good C++ book that includes a section on templates, or google for a C++ template tutorial (or both  )

Hi,
Can I rename/delete a file another process has open?
Thank you,

Simple answer: No
Complex answer: You can't while it's open. You can use MoveFileEx() to delay the rename/delete until the next reboot, and let Windows do it for you at startup.

You should check if the file is open or not before trying these operations

I was following some online examples on creating a
simple user form in visual c++, and I just came upon a
strange thing...that is, after putting in teh text
boxes and radio buttons etc, we go to put in a button
for the user to click, then according to the online
instructions, by double clicking on that button it
should take me to the code section where I can then
define what I want the form to do...but I just
noticed that in doing so, it takes me to the .h and
not .cpp file to define the code! That is kind of
strange..shouldn't I define my codes in the .cpp
file?
Also, when I try to put in additional logics, such as
declaring CString variables to do stuff with it, it
tells me CString is not declared...this is really
strange...
any assistance would be greatly
appreciated...
thank you!

What version of VC++ did you use. I think You can`t do that in VC++ 6. Corect me if i`m wrong.

I'm trying to disable the movement of the physical mouse, but still be able to set its position on my own, via SetCursorPos(). The only solution I could come up with is to get the current mouse sensitivity, set it to zero, then revert back to the original sensitivity when done. The promblem is that I have no idea how to do this, and could not find any information on MSDN or by searching online.
Alternatively, if anyone has a better method of achieving the same thing, I would greatly appreciate it.

Any way to force process to unload library????
I working on update component ( oracle ), it seems i can do LoadLibrary and FreeLibrary when needed just ok, except for dll's been locked by OS. I am aware of debug setting for that tells XP to unload every library it is not been used, but this is way to drastic.
Couple of other options comes to mind, but I don't want to reinvent the wheel and not even sure it would work.
1) From process A create process B, when done exit B hoping cleanup would unload DLL or may be just issue plain kill.
2) allocate memory, load dll (PE), do fixup entry table etc etc etc as long as darn LoadLibrary is not been used.
3) Call freelibrary until XP frees stupid library or I blow away my stack.
4) Other options?
Thanks,
Brian

Do what everyone else does.
You use MoveFileEx to get the files copied to the correct places during the system restart.
Prior to restarting, add a RunOnce program that will register the DLL while the system is starting up.
Tell user to reboot system.
This is the 'recommended way to repalce DLL that are in use.
Look at all the MS security udpates, constant reboots of machine, eh? Works for them.. should work for you!
