Hours of trawling the net and the closest I have come is to some C# examples.Does anyone know how I would be able to detect an ActiveSync connection in VB.NET for a a Windows XP app? What I want to do is get my app to detect a connection and check for a few files on the device, offering to transfer/ process them if available.

View 4 Repliesi'm kind of new to this. I'm using VB2008 and i need to write a code for recognizing a usb's details. like port number and letter and serial number if they have one. if i need to be more specific, then i have to say its for a machine that records data and i need to transfer that data over to my laptop through a gpib to usb cable. the cable has a specific "id" and i need to find that out and type it into the program interface that i'll make when i know how to detect that "id" so it can connect.i've read a few forum posts by others and they are really informative but not what i could use or i could not make it work.(yet)[URL]..and the other links posted there.for reading and helping. thats the clearest way i can explain. if anyone needs a more specific detail, just ask because i dont know if i left out anything else.

View 2 RepliesIs there anyway, in a program, to detect if a program is being run from inside a remote desktop session or if the program is being run normal in .NET 2.0? What I'm trying to do is, I create a timeclock application which will clock a person in and out and keep track. But this particular person, I suspect, is remoting into their computer at work, from home, and clocking in and out.

View 2 RepliesHow to add this functionality a vb.net windows service ? Here is what I've added, but not getting triggered when I tried to log off or lock the pc.
[Code]...
Recently while I was playing with VS 2008(VB), I have created an application for folder sync purpose... which is working fine. Then, I have created a windows service that does the same thing and it is also working fine(from application perspective). But, I have been trying to add some additional functionality to that new service. It keeps on running as long as System is ON.
But I would like to change the functionality to... as soon as user logs off Service should STOP, and should START when user logs into that PC. I tried to find some useful info online(related to my task) and all I could come up with was to add OnSessionChange(...) method to the service. But for some reason it is not working out for me(when I've logged off or other system events such as 'system lock').

After running the following code (which locks the computer), what code must I be applying to see if the user has successfully logged into the computer and that "Lock Screen" I'd so called has disappeared?

Private Function LockComputer()
LockWorkStation()
End Function
I will call "LockComputer", after that what do I do to see if the Lock screen so called by this function (after say 2 minutes) has disappeared or is still there asking for the password from the user.

I've done some digging and it looks like windows API can solve my problem but i really suck at using windows API and it looks like SetWindowsHookEx() can solve my problem but i don't know how to use it correctly. This is the code from Pinvoke that I modified to hopefully work for a mouse click. i'm having trouble getting this to work.

View 1 RepliesI want to add full GPS support into my application. The .Net 4.0 System.Device.Location namespace information here is perfect for my needs. When this was first announced and the Beta release was out, I got a GPS dongle, but I could never get Windows 7 to see it as a sensor and therefore make use of System.Device.Location. After many e-mails to Microsoft they would only confirm that they were using the GPS dongle that comes with a M$ Mapping product..
Does anyone know of any other Dongles that definately will appear as a sensor in Win7? I like the look of this one, it gets good reviews and is a nice size.Is there anyway of knowing that it will work, for example what Chipsets are supported as a Windows 7 Sensor, a lot of the information out there says that the Win7 implementation is really lacking..
