Deploy layered service providers(LSP).
You can track the statistics then.

Hello Sir,
Sorry to trouble you, LSP would be very difficult option when you targetting small computer.. also for installing LSP dll you need admin right... Please correct me if i am wrong!.

I believe Hooking Winsock.dll or using Free Ware library like WinpCap would better in this situation!

Hook winsock.dll or look for packet filtering library like

winpcap as I remember when I last played with sometime back deploys a filter driver. You need install rights for that Smile | :)

Hooking winsock.dll is restrictive. As someone pointed out iphelper apis would help, but it would work only on 2000/XP and above.

LSP works everywhere and is safe for what he is looking for.

But installing and Debugging LSP dll is itself it cumbersome task... hooking would be safe bet as you easily hook and unhook that dll according to your need but for LSP dll you have restart your computer...

Hello,

I got the following compiling error:

c:\program files\microsoft visual studio\vc98\mfc\include\afxtempl.h(86) : error C2679: binary '=' : no operator defined which takes a right-hand operand of type 'const struct PolygonX' (or there is no acceptable conversion)
c:\program files\microsoft visual studio\vc98\mfc\include\afxtempl.h(396) : see reference to function template instantiation 'void __stdcall CopyElements(struct PolygonX *,const struct PolygonX *,int)' being compiled

I am very strange because file "c:\program files\microsoft visual studio\vc98\mfc\include\afxtempl.h" is not a file in my project. How can I solve that?

I am almost exausted by this problem. A lot of thanks if someone helps.

Your code is directly or indirectly using a template class in that file. If you could post the piece of code that's causing the error, you could expect more help.

afxtempl.h is one of the MFC headers. It defines the MFC template-based collection classes: CList, CArray, and so on. Since you didn't directly include it in your code, you are evidently including some other file that does.

The error you listed occurs when an assignment operator has not been defined for a class used as an argument to one of the afxtempl.h classes.

Merry Christmas!Thanks for helps from all of you.
The following is the source code that caused the error. the code is from afxtempl.h.

template<class type="">
AFX_INLINE void AFXAPI CopyElements(TYPE* pDest, const TYPE* pSrc, int nCount)
{
ASSERT(nCount == 0 ||
AfxIsValidAddress(pDest, nCount * sizeof(TYPE)));
ASSERT(nCount == 0 ||
AfxIsValidAddress(pSrc, nCount * sizeof(TYPE)));

// default is element-copy using assignment
while (nCount--)
*pDest++ = *pSrc++; //this line causes error.
}
Here I list the error information again:
c:\program files\microsoft visual studio\vc98\mfc\include\afxtempl.h(86) : error C2679: binary '=' : no operator defined which takes a right-hand operand of type 'const struct PolygonX' (or there is no acceptable conversion)
c:\program files\microsoft visual studio\vc98\mfc\include\afxtempl.h(396) : see reference to function template instantiation 'void __stdcall CopyElements(struct PolygonX *,const struct PolygonX *,int)' being compiled

It seems I did not define the assignment operator of the argument. However, I defined it as the following:
struct PolygonX:public CObject
{

double minAngle;
CArray<cpoint,cpoint> ptArray;
public:
void operator=(PolygonX &src);
};

void PolygonX::operator=(PolygonX &src) {
minAngle=src.minAngle;
ptArray.Copy(src.ptArray);
}

I look forward to more helps!

Best regards,

I do not know if it is the cause of your error, but operator =() should not return void, it should return a reference to the current object.

PolygonX& PolygonX::operator =(const PolygonX &src) {
   minAngle = src.minAngle;
   ptArray.Copy(src.ptArray);
   return *this;
}

A good C++ book will explain it better, but the main reason is so that you can chain the operators. ie. one can do

MyObject1 = MyObject2 = Generate_temp_MyObject();

If MyObject::operator =() returned void then MyObject1 would not get assigned the value returned by Generate_temp_MyObject().

I have an ASCII-mode game, and I have a bomb... look:

I want that when the counter in the window's title reaches 0, fire (red ASCII 219 char) expands all through the screen... Can anyone give me an example of how I could do it? I have no idea... Thanks! Wink | ;-)

There are some good example in VB to get the
window title .
But u need constantly check for all windows
title or anyhow get the handle of the window
of ur game .

In VB ur work will be fast , never seen such

Has MFC dialog boxes gone multi threaded??

Robert Buldoc24-Dec-05 11:23

24-Dec-05 11:23

First of all Merry Christmas!

I noticed something weird in Visual Studio 2005. I haven't test my code in previous versions so I cannot confirm whether its merrit of VS2005 or else.

Ok, I have a dialog box application with 2 modeless dialog boxes which are created before the main dialog box in the application. I noticed there are 2 extra threads in the application with names "ThreadStartRoutine" and CRpcThreadCache::RpcWorkerThreadEntry" both at location _KiFastSystemCallRet@0 as shown in debug mode.

These 2 threads are created during the creation of the main dialog box in DoModal() function. I traced the exact creation point to Line 306 at dlgcore.cpp:
hWnd = ::CreateDialogIndirect(hInst, lpDialogTemplate,
pParentWnd->GetSafeHwnd(), AfxDlgProc);

Which is inside this function:
BOOL CWnd::CreateDlgIndirect(LPCDLGTEMPLATE lpDialogTemplate,
CWnd* pParentWnd, HINSTANCE hInst)

My question is what are these 2 threads for? and why are they created?

Any insight appreciated!!
Rob

My guess would be that the CRpc* stuff is related to Remote Procedure Call support in the MFC libraries. I'm pretty sure I've seen this before with MFC 7.1 apps. The other function, I have no idea.
