I don't know.
You should possibly post your calling code.BTW, what was the CoCreateInstanceEx return value?

This is my client code that calls the COM server on the remote machine...Thank u..

HRESULT hr;
IIGetFile2* pGetFile;

//
IUnknown* pUnknown = 0;
COSERVERINFO ServerInfo = {0,0,0,0};
wchar_t * remotemachine = L"servername";
ServerInfo.pwszName = remotemachine;
//MULTI_QI qi = {&__uuidof(IGetFile2),NULL,S_OK};
MULTI_QI qi={0,0,0};
qi.pIID = &IID_IUnknown;

//
IIGetFile2 * pInt = static_cast<IIGetFile2 *>(qi.pItf);
USES_CONVERSION;
CComPtr<IIGetFile2> Ptr1;
qi.pIID = &IID_IIGetFile2;

//

hr = CoCreateInstanceEx(CLSID_IGetFile2,NULL,CLSCTX_REMOTE_SERVER,&ServerInfo,1, &qi);
pUnknown = (IUnknown*)qi.pItf;

if(SUCCEEDED(hr))
{
AfxMessageBox("SUCCEEDED CoCreateEX");
}

pUnknown = (IUnknown*)qi.pItf;

hr = pUnknown->QueryInterface(IID_IIGetFile2, (void**)&pGetFile);
hr = pUnknown->Release();

if(SUCCEEDED(hr))
{
AfxMessageBox("SUCCEEDED QI");
_bstr_t bstrFileContent = pGetFile->GetFile2();
char* Text = _com_util::ConvertBSTRToString(bstrFileContent);
m_edit=Text;
UpdateData(FALSE);

}

Fine.
Is your server machine name "servername" (or simply is the name in your real code correct?

What about the hr (the CoCreateinstanceEx return value)?
And what about qi.hr value?

No, Its RDSServer ..I have given it correctly... Confused | :confused:

CoCreateinstanceEx hr=-2147023174
and for qi.hr I get access violation exception...

Your error code corrensponds to: "Error 0x800706ba - The RPC server is unavailable" see, for instance, this page [^] for some info.

Hi...I have another doubt..In case of testing both client and server on the local machine I have used this include statement...
#import "..\FileServer\FileServer.tlb"
using namespace FILESERVERLib;
But, When testing the server on the remote machine what kind of import statement Should I give..?
Thank u...

CPallini3-Mar-09 22:35

3-Mar-09 22:35

The import statement is used, on the client side, to build the client itself. It has nothing to with the testing phase (i.e. use always such statement to build the client and then forget about it...)

Thank u..So,u mean to say that it has nothing to do with my remote access...Right..

Enable MFC in Win32 DLL

Hi there.

I have created a Win32 DLL using VS2008.
Now, i want to use CString in code file lets say in dllmail.cpp

// dllmain.cpp : Defines the entry point for the DLL application.
#include "stdafx.h"


BOOL APIENTRY DllMain( HMODULE hModule,
                       DWORD  ul_reason_for_call,
                       LPVOID lpReserved
					 )
{
	switch (ul_reason_for_call)
	{
	case DLL_PROCESS_ATTACH:
	case DLL_THREAD_ATTACH:
	case DLL_THREAD_DETACH:
	case DLL_PROCESS_DETACH:
		break;
	}

	<code>CString str;</code>

	return TRUE;
}

I know that I need to include afx.h file and need to set "Use of MFC" option to Shared or Static linking, but still its not working.

Please suggest.
1. Where exactly I need to include afx,h file.
2. I can set "Use of MFC" option to Shared or Static linking or I need to use specific option.

Thanks
PanB

Another option, if you only need to use strings, is to use the STL (std::string) instead.

Thanks for the response.
I specifically want to use CString or any MFC class. I just want to know, how to use MFC classes in a Win32 based DLL.

I did this pretty long time back, but now I ma not able to do the same. Smile | :)

If you only need to use CString, include the file atlstr.h
