Thank you for the tutorial.
To help those with downloading problems, I found the built-in Windows 7 zip handler didn't like it, but as mentioned above, 7-Zip FileManager does unzip it. The trick? The first unzipping just creates one new file without an extension, this is another compressed file, so unzip this one with 7-Zip also :)

I'm running VB 2008 Express Edition. It ran a project update successfully with no logged errors, but just one Build error on running. It didn't like: Me.MainForm = Global.PCComm.PCComm.frmMain
Delete the duplicated PCComm.

Hope this helps!

The file is not corrupt, but it is a little confusing. I use WinRAR to handle my compressed files. I extracted the file that has no extension using WinRAR, then right-clicked on the extensionless file and opened THAT with WinRAR. The code is there, not corrupted.

Extract the included, extensionless file with WinRAR, then rename the extentionless file so it has a .ZIP at the end, then open, and extract again. The files are there. Windows doesn't understand why you would have a ZIP of a ZIP so it throws an error.

Hi,

Firstly, thanks for the sample it really helped me get going on serial communications.

However, why did you do DisplayData the way it is (i.e. using delegates, event handlers etc.). I replaced the code in DisplayData with that from DoDisplay and it seemed to work at least in the sample I created. I just wanted to see what would happen as I don't really understand the implications of the line.

_displaywindow.Invoke(New EventHandler(AddressOf DoDisplay))


Can you explain why this is done the way it is?

Many thanks.

thank you very much for this code.
I'm running into some problems though...
Conversion to vs.net 2008 worked fine, but there was an error with a duplicate PCComm
removing this seemed to do the trick.
The problem I am having is that the returned data from an external device returns giberish:
I get stuff like

Can anyone point me in the right direction on how to solve this?
