plz anyone can send me the Sample source code
or procedure of how to use and get my aim.

Well, I think MSDN [^] is the best resource for.
What does make you confused?

BTW CP [^] is another good resource.

Sorry, it seems I missed the target.

Here's one of my excerpts:

if (WBEM_S_NO_ERROR == hr)
{
    hr = pEnum->Next(WBEM_INFINITE, 1, &pClass, &ulReturned);
    if (WBEM_S_NO_ERROR == hr)
    {
        hr = pClass->Get(L"Description", 0, &v, NULL, NULL);
        if (VT_NULL != v.vt)
            TRACE("Description = %S\n", V_BSTR(&v));
 
        hr = pClass->Get(L"BaudRate", 0, &v, NULL, NULL);
        if (VT_NULL != v.vt)

I used once a third party dll inside another self-programmed dll.

The third party dll had a *.lib and a *.h files. I included the *.lib into the main Application and the header in MyDll.cpp

If the third party dll has no lib, then I think you should include the header in your cpp and load the dll dinamically into your own dll before using it.

After just include your own lib and header in the main application.

how can I get the exe's theApp in a regular mfc dll?

My project has two modules, one is mfc exe, the other one is a mfc regular dll.

Now I'd like to get the CWinApp* pointer of the exe in a exported function of the dll.

Can I use some kind of AfxGet...App/Module() to do that?

Have you heard about ADODb, OleDB, ODBC? If not then try to figure out what do you want to use and why. After finding a solution to this you can go and drill down to the basics and intricacies of the method you choose to use.

I sow the sample there is in this site how to add menu to the IE and actually done something quit similar in the pars, its was good for the IE6 but doesn't looks good on the IE7
Is there a way to add a 'real' drop down menu to an IE Toolbar button that will look like the original buttons that come with the IE7.

Hi EveryOne,

In ActivexDLL I have written a method called Connect(..)inside a class. The method exposes the functionality of connecting to another system using sockets.

The problem here is when I compile my project I am getting link errors(unresolved external symbol). These errors are thrown when winsocks methods are called like htos(),inet_addr(),connect() are called.

Unresolved symbol (upto my knowledge) are thrown when the function definition is unknown or its different from the one that is implemented. since I am using an inbuild function (used the header file winsock2.h) what might be the cause to the problem? How would I Overcome it. Please find the code below.

STDMETHODIMP CRAPClientX::Connect(BSTR serverIP, BSTR serverPort,BSTR *output)<br />
{<br />
	// TODO: Add your implementation code here	<br />
	/**output=SysAllocString(L"Connected");<br />
	return S_OK;*/<br />
	  //----------------------<br />
  // Initialize Winsock<br />
<br />
  WSADATA wsaData;<br />
  char returnString[150];<br />
<br />
  int iResult = WSAStartup(MAKEWORD(2,2), &wsaData);<br />
  if (iResult != NO_ERROR)<br />
    printf("Error at WSAStartup()\n");<br />
<br />
  //----------------------<br />
  // Create a SOCKET for connecting to server<br />
<br />
  SOCKET ConnectSocket;<br />
<br />
  ConnectSocket = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);<br />
<br />
  if (ConnectSocket == INVALID_SOCKET) <br />
  {<br />
  	sprintf(returnString,"Error at socket(): %ld\n", WSAGetLastError());    <br />
	*output=SysAllocString(_bstr_t(returnString));	<br />
	WSACleanup();<br />
	return S_OK;<br />
  }<br />
<br />
  //----------------------<br />
  // The sockaddr_in structure specifies the address family,<br />
  // IP address, and port of the server to be connected to.<br />
<br />
  sockaddr_in clientService; <br />
<br />
  clientService.sin_family = AF_INET;<br />
<br />
  clientService.sin_addr.s_addr = inet_addr("127.0.0.1" );<br />
<br />
  clientService.sin_port = htons( 27015 );<br />
<br />
  //----------------------<br />
  // Connect to server.<br />
<br />
  if ( connect(ConnectSocket, (SOCKADDR*) &clientService, sizeof(clientService) ) == SOCKET_ERROR) <br />
  {<br />
  	sprintf( returnString,"Failed to connect.\n" );<br />
	*output=SysAllocString(_bstr_t(returnString));<br />
	WSACleanup();<br />
	return S_OK;<br />
  }<br />
<br />
  sprintf(returnString,"Connected to server.\n");<br />
  *output=SysAllocString(_bstr_t(returnString)); <br />
  WSACleanup();<br />
  return S_OK;<br />
}<br />

Not linking to the lib file in which these functions are defined might be one cause Smile | :)

. So, did you link your project to ws2_32.lib ?

Once I posted this question, I got the question which u asked; in my mind and then included the library (which I missed out earlier Frown | :(

)WS2_32.LIB. So I fixed it in the time you answered the question. sorry for wasting your time Cedric and thanks for the reply.
