I have an MC++ written control.
I have added it to the C# toolbox.
When I try to insert it into the form [by drag/drop] I get a message box with this *very* informative message :-
Exception from HRESULT: 0x80131019
Blast!!!

I just wrote a message to you about that. What a coincidence? I did not know that you would land into this problem so soon. Ok this is interseting you can have a look at my article Developing windows forms control with MFC. Basically you have to click on the reference and set copy local to false.

Cool! Also had to copy the DLL to the output directory

What's worse is that I caneasily add the control via code. It's just that the form designer refuses to understand the control
Is there any known issue where the C# form designer cannot understand a control made with MC++ ???

Hello,
This is with regard to writing Forms controls using MC++.
Has anyone made any?
If so, what extra steps did they have to take?

These are the steps I have done right now :-
#using "..\testcontrol\Debug\testcontrol.dll"
....
using namespace testcontrol;
....
Then I have a member in my class as follows :-
Class1 *m_c;
This is all okay.
Now if I do this anywhere :-
m_c = new Class1();
I get this exception when I run it :-
System.IO.FileNotFoundException
Blast!!!!
It found the file alright!!!
Else how would it even compile properly

Place testcontrol.dll in the output directory of the application which you are building.

Just did that Rama
Sucks huh?
I thought the #using would tell the blasted compiler to tell the blasted linker to look for it there

It's all assembly search policy. I dream to write an article on that. You should be glad that you are not writing the client app in C# in that case there are more interesting issues involoved - C# with MC++.

Nish,
I use MC++ for all the projects and C# for Windows forms. Now when I use the C# DLL I need to make sure the DLL is in the compilers path and the exe path. I just change the output folder.

WELL ! I JUST WANNA ASK ABOUT CREATING A SCOKET THROUGH CSocket CLASS
I TIRED THIS CODE (BELOW) BUT IT DIDNT WORKED OUT!
CODE:
CSocket *c = new CSocket();
c->Create(port) ;
it doesnt create a socket .
I EXPECT TO GET THE CODED PROCEDURE OF CREATING A SOCKET! IF ANY ONE CAN HELP ME 
|

Ok In MC++ you can use TcpClient() TcpListener() and Socket()
Look at this samples by this nice guy called Albert Pascual
http://www.codeproject.com/managedcpp/howtoproxy.asp
and
http://www.codeproject.com/managedcpp/get_the_ip_out_tcpclient.asp
where you can use something like this to listen in a socket :
TcpListener * pTcpListener;
TcpListener = new TcpListener(80);
TcpListener->Start();
TcpClient * pTcpClient;
pTcpClient = m_TcpListener->AcceptTcpClient();

I have a C# dll and inside MC++ I tried to use it!
#using "mydell.dll"
I get this error:
fatal error C1001: INTERNAL COMPILER ERROR
(compiler file 'msc1.cpp', line 2844)
Please choose the Technical Support command on the Visual C++
Help menu, or open the Technical Support help file for more information

Confirmed is a bug!!! NOW WHAT? Not work around? I am so mad!!!
BUG: "C1001 Internal Compiler" Error Message When You Compile Code with Typename Identifier
--------------------------------------------------------------------------------
The information in this article applies to:
Microsoft Visual C++ .NET (2002)
--------------------------------------------------------------------------------
SYMPTOMS
When you attempt to compile the sample code fragment from the "More Information" section of this article, you receive the following compiler error message:
t.cpp(16) : fatal error C1001: INTERNAL COMPILER ERROR
(compiler file 'msc1.cpp', line 2844)
CAUSE
This behavior occurs if a template class contains a derived member method as a typename identifier. The compiler error message occurs only when you compile the code in a Managed C++ project. You do not receive this error message when you use a native code compiler.
STATUS
Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article.
MORE INFORMATION
Steps to Reproduce the Problem
Create a new Managed C++ application, and then replace the default code with the following:
#include "stdafx.h"
class A {
public:
void FA();
int i;
};
class B : public A {
public:
virtual void FB();
int k;
};
template <typename f,="" const="" f="" pf="">
class CLockFunc0 {
public:
CLockFunc0() : m_pF(pF) {}
~CLockFunc0() {}
private:
F m_pF;
};
CLockFunc0<void (b::*)(),="" b::fb=""> t1;
Compile the program.
You receive the error message described in the "Symptoms" section of this article.

I am looking some clarifications for the use of IJW and p/Invoke.....
I have a DLL which is written in Visual C++ (NOT a COM component). I am planning to use that from Visual Basic.NET. Infact there is a VB code earlier written to call that DLL. Now the application is being rewritten in VB.NET and I want use that DLL. What are the ways I can use that DLL?
I found the following ways (I am not 100% what I found are correct or not)
1) Use P/Invoke in Visual Basic.NET and call the functions in the DLL
2) Recompile the C++ DLL using IJW switch so that it will be a managed one. Since my VB.NET code is a managed one, I can access that..Is this approach correct? or do I need to write wrappers over managed C++ obtained after compiling with IJW switch to use in VB?(I heard that after compiling with IJW you can use only with managed C++ and not with any code written using other languages like VB.NET or C#)
Whar is the performance difference between IJW and P/Invoke ?
Can anyone give me an answer?
Thanks in advance,
Madhu.

He is talking about the /clr switch in C++ compiler options. (BTW. He posted the same question to DOTNET mailing list)
