You don't need to wrap CSocket. Here is how you can use CSocket in an MC++ application using IJW
AfxSocketInit();
CSocket s;
s.Create();
String* cmd = "GET /\r\n\r\n";
String* url = "www.google.com";
if(s.Connect((CString)url,80))
{
s.Send((CString)cmd,cmd->Length);
char buf[127];
while(int n = s.Receive(buf,128))
{
buf[n]=0;
System::Console::WriteLine(buf);
}
}
s.Close();

virtual ~CListeningSocket(void){}
//{{AFX_VIRTUAL(CListeningSocket)
public:
virtual void OnAccept(int nErrorCode);
//}}AFX_VIRTUAL
// Generated message map functions
//{{AFX_MSG(CListeningSocket)
// NOTE - the ClassWizard will add and remove member functions here.
//}}AFX_MSG
};
//***********************************************
public __gc class M_listeningsocket
{
public:
M_listeningsocket();
~M_listeningsocket(void);
CListeningSocket *ptr3;

void Create(UINT port);
bool Listen(void);
};
}
//********************************************************

}
void mfcdll::M_listeningsocket::OnAccept(int nErrorCode)
{
ptr3->OnAccept(nErrorCode);
}
void mfcdll::M_listeningsocket::Create(UINT port)
{
if(ptr3->Create(port))
MessageBox(0,"create succ....",0,0);
else
MessageBox(0,"create not succge....",0,0);
}
bool mfcdll::M_listeningsocket::Listen(void)

Hi,
I had posted this earlier here, but got no response.
I am trying my luck again (by changing the Subject Line...;))
I have a User Control (created using Man C++)
When I try to place this Control on a form, the Form Designer throws an Exception( 0x80131019).
And I am not allowed to place the control on the form.
This happens when the CopyLocal Property of the Reference is True.
But if I change the CopyLocal property to False,
the Designer wholeheartedly accepts the Conrtrol.
The Form Designer doesnt behave this way with controls made using C# or VB.Net.
Can someone please tell me what difference does CopyLocal property
make to the Form Designer ?
Why does this happen only with Controls created in Managed Cpp?
My control does nothing extraordinary, but just some Drawings in the OnPaint().
Please, somebody Help me.....
Thanks,
Firoz

Your assembly needs to be registered in the GAC. To do this it first needs a "strong name", sort of like a GUID.
Use SN.exe to generate a strong-name key file. In your AssemblyInfo.cpp file, specify the key file as a parameter to the AssemblyKeyFileAttribute() attribute. Rebuild your assembly.
Now use Gacutil.exe to register the assembly in the GAC. This step can be done in a custom-build-step if desired.

Hey coders....
Okay I am just trying to create an instance from HWND and it won't let me.
ie.
<br />
using namespace System;<br />
#using <mscorlib.dll> <br />
<br />
public _gc class COO<br />
{<br />
HWND m_hwnd;<br />
public:<br />
COO(HWND hwnd)<br />
:m_hwnd(hwnd)<br />
{}<br />
};
When I hover over HWND it gives me (typedef HWND__ *HND) so I assume it is recognizing it but for some reason I can't use it....
If anyone could tell me why and how to get around this it would be much appreciated. Thanks...

The Visual C6's resource management really stinks the joint. Is it any better in .NET based on your experiences? I have been working on a multiple project workspace(about 25 projects in a workspace) and more often than not the dialog boxes give you a headache. Is it any better in .NET?

how could i unzip .zip files to a user entered dir in mc++
|
|

The same way you do it in regular C++, find or write a ZIP unpacking library and use it. Not much of an answer but its the truth 
There are various ZIP libraries out there; one is available at icsharpcode.net[^] according to the site it is GPL'd but the site also says at the bottom that you can use it in a closed-source app.

James' solution is of course the correct way, but if you (like me  ) are lazy, you can instead just download Info-Zip and spawn it to do your bidding. Less flexible, and not completely .NET of course, but still a useful technique if your needs are modest...

Hi,
I created a CustomConrol using ManagedC++.
This Control is Used in a C# Application.
When I Drop/Draw this Control to a Form, I get an error message
"Exception from HRESULT : 0x80131019".
But when I set the CopyLocal property of the Reference to False,
the Control is properly Drawn.
Why does this happen.
Why it gives Error when CopyLocal is True?
What does the Error code (0x80131019) mean ?
(I was not able to find this HRESULT Code in WinError.h)
Thanks,
FiroZ
