Ok problem is solved. It was me who was making mistake while passing command which i didnt mentioned in this post.

I was just missing new line character while sending commands.

Thanks for posting comments for helping me out.

sTest are commands sent to the terminal.
Suppose sText is ATE0 then in telnet i am getting ATE0 and then OK.

sockP_DataArrival is triggered once and i get back "ATE0" but not OK.

I tried different commands where i expect more then 1 reply for a command but i am getting databack just once from the terminal.

Ok i figured out that the header file MainFrm.h is coming from ..\rhub\mainfrm.h.
& in that rhub directory too it has Mainfrm.cpp which has Log function.

Now what do i need to do to call the function from that .cpp?
Should i add that cpp in my project ?

Advice
Thanks

Perfect .. This worked fine ..
Thanks

Thanks Nishant.
Perfect.
Now i got an array from my calling application to C++.
Now from this C++ function if i want to pass the array or array values (received from calling app) to C# class library, is there a way to do that.

Please let me know.

Thanks.

Actually my question was not completely clear. My bad for that.
Actually the Win32 C++ is just the entry point for the calling application where it will call a function from C# class library and pass the same parameters.
Your code works perfect.

But what i want is that in my Win32 app Test function i am taking the parameters (Test(char **files, int count) passed from calling function Test(string[] files, int count). Just like your solution.

Now i don't want to use the values in the C++ application, but C++ app Test function will call a function from C# class library where i want to use the string array.

Ex: string
void _stdcall Test(char *lFile, int ver)
{
//Initialize COM.
psShrinkGrowD->Test(_bstr_t(largeFile), version);
// Uninitialize COM.
}
Here i am passing string from my calling application to C++ (char *lFile) which in turn calls Test function from C# class library where it is again being read as string.

Thanks

Ok good.
Will give a try tomorrow.

Thank you so much.
Actually i am creating a Win32 wrapper DLL around C# class library because my dll will be used by vb.net and also Delphi.

Also is it possible to create multidimentional array in Win32 C++ ?

Thanks. Appreciated.

It worked.
Thanks

Application.DoEvents() solved the problem.
Thanks

Here is my function. Could u plz let me know if anything is wrong with the function.
extern "C" __declspec(dllexport)
int _stdcall Test(char *largeFile, char *smallFile, int version)
{
//Initialize COM.
HRESULT hr = CoInitialize(NULL);

IShrinkGrowDPtr psShrinkGrowD(__uuidof(ShrinkGrowD));
long sResult = 0;

psShrinkGrowD->Shrink(_bstr_t(largeFile), _bstr_t(smallFile), version, &sResult);

// Uninitialize COM.
CoUninitialize();
return sResult;
}

I am a bit new to Win32. Also if it is a normal dll i should be able to register dll but i am unsuccessful for that.

After adding dll to the System32 folder, running the application gives me external component gives an exception.

Also i am initializing & Uninitializing COM
HRESULT hr = CoInitialize(NULL);

IShrinkGrowDPtr psShrinkGrowD(__uuidof(ShrinkGrowD));
long sResult = 0;

//psShrinkGrowD->Shrink(_bstr_t(largeFile), _bstr_t(smallFile), version, &sResult);

// Uninitialize COM.
CoUninitialize();

I have different functions for shrinking the file, growing the file, checking the version, testng crc.
Example of shrinking function is above. Implementation is same which calls functions from my Class library.
I hope u got a bit idea about my application.

Let me know if can help me to create DLLRegisterServer function.

Thanks

Ok .. so i have the function named Test in my .def file.
LIBRARY "1WIN32"
EXPORTS
Test
Now i build the application & dll is created. How can i register the dll ? Let me know.
Thanks

DllRegisterServer PRIVATE
DllUnregisterServer PRIVATE gives me error unresolved external symbol DllRegisterServer

extern "C" __declspec(dllexport)
int _stdcall Test(char *largeFile, char *smallFile, int version)
{
//Initialize COM.
HRESULT hr = CoInitialize(NULL);

IShrinkGrowDPtr psShrinkGrowD(__uuidof(ShrinkGrowD));
long sResult = 0;

psShrinkGrowD->Shrink(_bstr_t(largeFile), _bstr_t(smallFile), version, &sResult);

// Uninitialize COM.
CoUninitialize();
return sResult;
}

I have used __declspec(dllexport) in all the functions i used.
& have added the function name in .def.

I think my problem is solved.
Your document was really helpful.
Thank you.

This helped me too:

Problem:
namespace GS
{
public interface ISGD
{
unsafe int S(char* lF, char* sF, int vr);
unsafe int G(char* lF, char* sF, int vr);
};
public class SGD : ISGD
{
}

Creating .tbl and imported it.
#import ..path..
using namespace GS;
its fine.
Now created test function.
Inside that if i do GS:: i am getting __GlobeShrink (showing as struct)
Doing GS::__GS gs(__uuidof(SGD)); //gives me error.
error C2065: 'SGD' : undeclared identifier
error C2079: 'gs' uses undefined struct 'GS::__GS'


I have a struct defined in the class library. Is it showing that ?
Why i am not getting interface name in it?

So in my class library where there are entry points i need to create an interface which will contain the declarations of the functions which i am going to use in Win32 Dll.
And need to inherit that to class in my C# CL.

Just correct me when i am wrong please.

No i am not. I am reading through the chapter.
If any doubt will come back.
Thanks for the link.

No. I already created Win32 Dll and created few functions in that.
Just need to understand how to call external managed DLL and use functions in this unmanaged Win32 Dll.
Thanks

Thank you for the link. But i need to create Win32 Dll.
So can u provide with a link for COM Interop to access Dll.
Thanks

I know C++.
Can u please provide with a link with good reference.

Thanks

I have created new Win32 Dll project.
Adding reference doesn't show COM.

No John is right too. Eliminating lamda makes it simpler to use. I just tried ParameterizedThreadStart and it eliminated my error too without assigning it to temporary string.
Think lamda functions in a different way.

No .. i can use unmanaged code too.
I just want to copy the content located at source memory location to destination memory location x no of characters.

I am using interopservice but i dnt knw the syntax to copy the string content to a specified location.

I think there should be something in C# directly which can do that.
