Is it possible to read data from the transmit and receive buffer of serial port. I'll be sending some data to the Tx line and the hardware will be sending response to the Rx line. How can I monitor both the data from the Tx & Rx line. We'll be using the same port to write to Tx line and monitor both lines. Is it possible ?

Have a look at PortMon[^].
PortMon will log all IRP's to the driver and the data sent/received.

Its not possible to read and write from the COM port at the same time, only one operation is supported at one time.

Don't use NULL as the first argument to GetModuleFileName().

See here. The handle comes to you in the DllMain() function of your DLL. If you don't have access to DllMain(), you might also be able to use GetModuleHandle() to get the DLL's handle.

Hi all,
I am working on Outlook Addin using vc++. I am facing problem to the get_Subject or GetSubject method . Please give me the solution for this I have given the code snippet below....
Thanks In Advance..

                // Variable Declaration<br />
	        CComQIPtr<Outlook::_Application>Application;		<br />
		CComPtr<Outlook::_Explorer>pExplorer; <br />
		CComPtr<Outlook::Selection>pSelection;	 <br />
                CComQIPtr<Outlook::_MailItem>pMailItem;     <br />
                char *str=new char[100]; <br />
              	IDispatch *pDispatchItem;			<br />
		CComVariant covIndex;<br />
		BSTR subject;	<br />
<br />
                pExplorer =Application->ActiveExplorer(); <br />
		pSelection=pExplorer->GetSelection();<br />
		covIndex.vt = VT_I4 ;<br />
		covIndex.lVal =1;<br />
		pDispatchItem=pSelection->Item(covIndex);				        	pMailItem=reinterpret_cast<_MailItem  *>(pDispatchItem);			<big>pExplorer->get_Subjet(&subject);  // exception at this statement</big><br />
		str=_com_util::ConvertBSTRToString(subject);

Most probably the statement pExplorer =Application->ActiveExplorer(); has not succeeded .
Try
if(pExplorer)
pExplorer->get_Subjet(&subject); // exception at this statement
And if the if statement failes , then rewrite the allocation code as
while(pExplorer!=NULL)
{
pExplorer =Application->ActiveExplorer();
}

These problems arise mostly in plugin codes becasue , plugin try to use the default memory allocated for the application to which this plugin is intended (here outloook exe)

I am Very Sorry. I wrote the wrong statement in my question, the statement I intended to write is as follows...
pMailItem->get_Subjet(&subject);

But....
pExplorer->GetCaption();
this statment is giving the proper output..
Means there is no problem with pExplorer.

Then what is the the problem with _MailItem even sometimes get_SenderName is giving the output.
Please give me the solution.

Thanks Again for ur Immidiate Reply and Helpful suggestion...

You will have to initialize the CComQIPtr Application pointer with the object from Outlook. What I can assume from your code is that you are not initializing this pointer with the outlook object. How does your application know that it has to get an instance for outlook, so this fails and then when you do something to get the subject it causes an exception to be thrown.
you can also try debugging your application.
Try something like this. I haven't checked the code but it might help you.

CComQIPtr<Outlook::_Application> spApp;
HRESULT hr = spApp.CoCreateInstance(__uuidof(Application));
if (FAILED(hr)){
MessageBox("Unable to instantiate Outlook.","Outlook Error",MB_OK);
return 0;
}

hello
What do you do to Sql.pData[i] before callinng AddString() ?
Did you check if there are values in Sql.pData ?
Put a break point there ?
Did you verify if you have called CMyComboxClass *myCombo = new CMyComboxClass() ?
