I don't know.
You should possibly post your calling code.BTW, what was the CoCreateInstanceEx return value?
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

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...
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.

Thank u...Let me try out...

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...
|
|
|
|

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...)

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

Which means what exactly ?

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.

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

Hi,
I'm new in C++ and have a very basic question.
suppose that I have a string such "23" how can I convert in to a byte
0x23
I have tried:
char* str = "23";
char c;
sscanf(str, "%x", &c);
but the char c is 4 bytes in memory and this is not safe!!!
how can I do that?
Thanks,
|
|
|
|

You could only mean two things.
1. Conver the number 23 to hex.
2. Take ascii value of every character, which is again a number and convert it to hex.
You mean something other than these? If yes, you are wrong.

|

Why don't you store it into an integer instead of a char ?

That's because %x indicates you want to read an integer. Read it into an integer, bounds check it if you want, then assign it to the character.
If you want to ensure you only read 2 hex characters from the input, use a width specification, like this:
sscanf(str, "%2x", &int_value);
Java, Basic, who cares - it's all a bunch of tree-hugging hippy cr*p

you may use
char * str = "23";
char * endptr;
char c = (char) strtol(str, &endptr, 16);

typedef unsigned char byte;
typedef wchar_t charw;
typedef const charw ccharw;
ccharw *CharHexL (L"0123456789abcdef");
byte HexToByte( charw C )
{
C = towlower(C);
if( C >= CharHexL[ 0] && C <= CharHexL[ 9] ) return( byte(C-CharHexL[ 0]) );
if( C >= CharHexL[10] && C <= CharHexL[15] ) return( byte(C-CharHexL[10]) + 10 );
return(0);
}
inline byte HexToByte( charw C1, charw C2 )
{
return( (HexToByte(C1)<<4) + HexToByte(C2) );
}
If the string has an odd number of characters pass the first char to HexToByte(C) to get the values for the first byte. Walk the rest of the string two characters at a time using HexToByte(C1, C2) to convert the pairs to bytes.

The idea that I can be presented with a problem, set out to logically solve it with the tools at hand, and wind up with a program that could not be legally used because someone else followed the same logical steps some years ago and filed for a patent on it is horrifying.

I want to cut the specified part of the wmv file using directshow editing services.I am able to cut the file using WMASFWriter.
But my problem is that WMASFWriter encode the video and gives the
bad quailty of video. so my question is that which filter is used so that I get the best quailty and do not encode the video.
