Thanks, Anders pal!
I will accept your advice.
I cross-posted because my boss is asked me to hand in the
project immediately, but I am in trouble as you
see.
Cheers,
George

Hi, everyone!
I have searched the help page for "size_t" but failed
to find the help page and information about "size_t".
Where can I find the help page or information about
"size_t"? Can you paste detailed information about
"size_t".
Thanks.
Cheers,
George

Thanks, Nish, my old friend!
I still have a question.
What means "typedef _W64 unsigned int size_t;"?
Does it mean the three objects
_W64, unsigned int and size_t are the same?
Have a nice weekend,
George

Hello George
It means size_t is a synonym for _W64 unsigned int
And as far as I could make out _W64 has been defined as nothing. Perhaps someone else can correct me here if I am wrong.
So as far as you are concerned you can cast the size_t to an unsigned int
Regards,
Nish
p.s. I found the cross posts humorous, specially your choice of the ATL/WTL forum

Thanks, Nisk pal!
I think I have fully understood the meaning
of size_t under your directions and other pals
in ATL/WTL forum. 
Have a nice weekend,

As far as I can see, there's no header file in Managed C++ ?!?!?!?! everything seems to be inlined in the class like this in either a .h or .cpp file that can be included in the main project file:
<code>
__gc public class MyForm : public Form
{
public:
MyForm()
{
Text = S"MyForm";
};
};
</code>
The question, is, can I separate the implementation for the declaration ? to have a header file and a code file ( .h and .cpp ) ?
Are there rules, guidelines or specification ?
Thanks.
Max.

I am trying to get my C program to open and close another application.
ShellExecute (NULL,"open","C:/myproject.exe",NULL,NULL,SW_RESTORE);
works to open the application, but I can't get it to close. I've tried
DestroyWindow("C:/myproject.exe");
but it doesn't work. Can anyone tell me what to use for the file reference for DestroyWindow?
Or is there a completely different way to do this better?

Hi squeaky
Read my article below :-
http://www.codeproject.com/system/newbiespawn.asp
That'll show you how to use CreateProcess which gives you both the process handle and the thread handle for the main thread. Now use EnumWindows to enumerate all top level windows. Call GetWindowThreadProcessId on each HWND and compare with the thread ID you had saved earlier. If they match, post a WM_CLOSE message to this HWND.
Hope this helps,
Nish

I have a dll where i write
// RMLib1.h
#pragma once
#using <mscorlib.dll>
#using <system.runtime.remoting.dll>
using namespace System;
using namespace System::Runtime::Remoting;
using namespace System::Runtime::Remoting::Channels;
using namespace System::Runtime::Remoting::Channels::Tcp;
namespace RMLib1
{
public __gc class HelloObj:public MarshalByRefObject
{
public:
HelloObj();
String* Greet(String* name);
private:
int numGreet;
};
}
#include "stdafx.h"
this is implementation of these methods
#include "RMLib1.h"
using namespace RMLib1;
HelloObj::HelloObj()
{
Console::WriteLine("HelloObj Activated ");
}
String* HelloObj::Greet(String* name)
{
numGreet++;
String* greeting =S"Hello" ;
return greeting;
}
Inother project i try register this objas remote services
using namespace System;
#using <system.runtime.remoting.dll>
using namespace System::Runtime::Remoting;
using namespace System::Runtime::Remoting::Channels;
using namespace System::Runtime::Remoting::Channels::Tcp;
#using <rmlib1.dll>
using namespace RMLib1;
// This is the entry point for this application
int _tmain(void)
{
Console::WriteLine(S"Hello World");
TcpChannel* chan = new TcpChannel(8085);
ChannelServices::RegisterChannel(chan);
Console::WriteLine(S"Registering Hello Obj As SingleTon ");
RemotingConfiguration::RegisterWellKnownServiceType(Type::GetType("HelloObj"),"HelloObj",WellKnownObjectMode::Singleton);
Console::WriteLine(S"Waiting For Remote Calls");
Console::WriteLine(S"Hit Enter To Exit ");
Console::ReadLine();
return 0;
}
I can compile this code but when try to excecute it gives me
error
System.ArgumentNullException:Value Can not be Be NULL Parameter Name:Type
This line is giving Problem Any Idea.............
RemotingConfiguration::RegisterWellKnownServiceType(Type::GetType("HelloObj"),"HelloObj",WellKnownObjectMode::Singleton);

Folks,
I was wondering if there is a way to convert String(managed type) to Cstring(unmanaged type) in MC++?
Appreciate your comments/replies.
CHEERS

#include <vcclr.h>
then, call PtrToStringChars(), passing the managed string:
String* fx_string = S"Hello, World";
CString mfc_string = PtrToStringChars(fx_string);

I had to check to see why this works because it shouldn't - unless there exists a constructor for CString that takes a String*.
And there is. CString has a constructor that looks like this - note it does exactly what I prescribed (and pins the pointer, which I think I neglected to do):
CStringT( System::String* pString ) :
CThisSimpleString( StringTraits::GetDefaultManager() )
{
const wchar_t __pin* psz = PtrToStringChars( pString );
*this = psz;
}
good catch.

 Yeah, I was using this when comparing a String* to a CString in my N-Track program (MFC/MC++ mix). But I just realized that, that is inefficient, because each time a CString object was being allocated on the stack
