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);
}
