View 7 RepliesRouting Modem Audio Out To SR Engine Audio Input Under VB / VBA?
May 20, 2009I have a database application developed around Access with VBA,I have used the Speech SDK and developed an application that in conjunction with MSCOMM 6.0 library calls into a remote IVR system.It sends in the credentials and queries information in response to that IVR's verbal requests. All seems successfull except for one problem;I'm using a shared SR engine and its using the system microphone as its audio input, this in turn gets the sound from the speakers which are routed to the telephone line through the modem. Of course this has a number of disadvantages - noise added to the sound from the environment and sound quality degredation as well as speaker volume dependency.
I would like the SR engine to take its audio input from the modem in paralell with the sound that goes to the speakers (so we can listen in to the call as well). This means that I must route the system audio output to the SR engine audio input. It seems that I must use an InProc SR instance - however in VBA that type is not recognized - since the shared SR uses the microphone as input by default. there is some statement to the effect that it is difficult in Microsoft's Help file. I'm unable to set the SR audio input to the modem output stream in VBA.As needed I can accomplish the C++ interface using an ActiveX object or a DLL to expose the missing API to VBA?

View 1 RepliesAnalyze An Excel Document With Coordinates For A Robot?
Jun 28, 2011This program is being used to analyze an excel document with coordinates for a robot. The entire program works...My boss indicated he wanted me to throw an exception in whenever a coordinate that wasn't being given a tolerance wasn't supposed to move, he wanted the program to give an error message. Which I figured out and outputs a message box saying "Result Compare Fail!"
Now here is my dilemma..whenever I encounter a section in the excel sheet analyzing multiple variables, I still get the error message, because the program doesn't think of it as multiple variable coordinates changing. Is there an easy way to fix this? I'm stumped! This is one of the cases, but they are all very similar.

Packet Capture And Threading, Capture Library Waits For "thread Stop"
Apr 5, 2009So I am hacking together an app which listens to traffic using SharpPcap library, it reconstructs the packets from sessions using the code from TpcRcon.
Listening and reconstructing part work on their own . What I want is on each packet arrival main window gets an event so it can display the packet , and when session is reconstructed display a complete packet (I am interested in HTTP ones) . -That is where it breaks with weird symptoms: for example right now it does not stop on invoking stop listening method - the sharppcap library function hangs there forever waiting on this line of code : m_pcapThreadEvent.WaitOne();//wait for the 'stopped' signal from thread
I also had it not working and crashing in sharppcap function because I had omitted one parameter in form delegate- which makes no sense, because form delegate does not deal with packet capture at all and only reacts on "New Packet" event from my "Listener" class (which is only there to notify main form)
My app starts as module main instancing class "Listener". MainForm has it
registered as friend with event and handles even "New Packet"
Main Form:
Private Sub uiListenStart_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btListenStart.Click
