Trying To Make A Serial Connection From A Windows App
Feb 16, 2011
Trying to make a serial connection from a windows app in vb.net to a com port through pc.also, can i make a separate listener windows app in vb.net that has its own virtual com port (for testing).the function of this connection is to simply pass variable states through the serial port on the pc to a microcontroller, which will interperate the code and perform actions based on the variable states.is there an easy way to implement serial port data communication in vb.net?

I write program for Windows CE that should work with Serial ports. I use object System.IO.Ports.SerialPort. Everything works well but when I close program and open it again, I receive error: Port is in use! At the end I write:
port.close()
port.dispose()
And If I add this:System.GC.collect() than everything begins to work But problem is that computer gets stuck when garbage collector is called for each port. If I tried to use collector somewhere else, it doesnt "collect" ports and they look like used if program starts again.

I am having trouble running a VB.NET 2.0 Serial Port application in Windows 7. I developed it in Windows XP, it ran fine in Windows 2000 and now when the company upgraded the machines to Windows 7, the application does not kick off. All platforms were/are 32-bit. I did some research online, but have not found anything relevant to resolve my issue. Does anyone know what the issue might be and the possible solution to it?

I am having my app available for 30days free trial, but after that you have to purchase a serial, how can i make my app only recognize a specific type e.g NumberLetterLetterNumberLetterLetterNumberNumber-NumberLetter-Letter:NumberNumberNumberNumber?
OR what would be the easiest way to have serials recognised?

I'm fairly new to Visual Basic (VB), but I've already got running code to access all my serial port. The problem is I want to load multiple serial ports into an array and loop through them in my functions. The program allows me to create ports(), but fails when I try to populate it.
Dim ports As IO.Ports.SerialPorts()
ports(0) = SerialPort1
Where SerialPort1 is an object I draged from the Visual Studio toolbox.

I finished my application and i have a registration system which checks with my server if the key is correct the program is validated and the trial part is removed. So my problem is that i do not want to seat all day by the computer and make serial keys. I want to make a program that will generate the keys for me. I looked into RockXp but that's a third party software.

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.
