Hello,
I'm trying to send a FAX using Windows FAX Console programmatically with "FaxSendDocument" in "winfax.dll". I'm getting a "parameter incorrect" message. Can you help me out? - What's wrong with my code? - Is there a better way? - Would you suggest using a 3rd party component? Thanks in advance for you answer. Here's the code:

void TfrmMain::FaxDocument()
{
	HANDLE               fxHandle;
	PFAX_JOB_PARAM       pfxParam;
	PFAX_COVERPAGE_INFO  pcpInfo;
	DWORD                dwJobId;
	LPCTSTR              pszServerName = NULL;


        // POINTING to local machine right now:
	// pszServerName = 
	//////////

	// Connect to the fax server
	FaxConnectFaxServerPtr =
	   (FAX_CONNECT_FAX_SERVER_A)GetProcAddress(FDllHandle, "FaxConnectFaxServerA");
	if(FaxConnectFaxServerPtr)
	{
		if(!FaxConnectFaxServerPtr(pszServerName, &fxHandle))
		{
			ReportOSError();
			ShowMessage("ERROR connecting to the FAX Server!");
			return;
		}
	}

	FaxClosePtr = (FAX_CLOSE)GetProcAddress(FDllHandle, "FaxClose");

	// Prepare and allocate job params and cover page data
	FaxCompleteJobParamsPtr =
		(FAX_COMPLETE_JOB_PARAMS_A)GetProcAddress(FDllHandle, "FaxCompleteJobParamsA");
	if(FaxCompleteJobParamsPtr)
	{
		if(!FaxCompleteJobParamsPtr(&pfxParam, &pcpInfo ))
		{
			ReportOSError();
			if(FaxClosePtr)
			   FaxClosePtr(fxHandle);
			return;
		}
	}

		 pcpInfo = NULL;

	const String TempFileName =
		"c:\\Bill\\faxserver.doc";
	// Try to send
	FaxSendDocumentPtr =
		(FAX_SEND_DOCUMENT_A)GetProcAddress(FDllHandle, "FaxSendDocumentA");
	if(FaxSendDocumentPtr)
	{
		if(FaxSendDocumentPtr(fxHandle, TempFileName.c_str(), pfxParam, pcpInfo,
		   &dwJobId))
			   ShowMessage("SendDoc succeeded");
		else
			{
				ReportOSError();
				ShowMessage("ERROR with FaxSendDocument!");
			}
	}

	// Cleanup here:
	FaxFreeBufferPtr = (FAX_FREE_BUFFER)GetProcAddress(FDllHandle, "FaxFreeBuffer");
	if(FaxFreeBufferPtr)
	   FaxFreeBufferPtr(pfxParam);

	if(pcpInfo && FaxFreeBufferPtr)
	   FaxFreeBufferPtr(pcpInfo);

	if(FaxClosePtr)
	   FaxClosePtr(fxHandle);
}
