You can send SMS through your mobile phone's built in GSM modem but you have to connect it to your computer through an infrared connection, I'm not sure whether a modem can be connected to a computer through a USB cable you can see your phone's reference manual for this purpose. You can easily send SMS by using AT commands or you can also use the .NET Phone Communication Library for this purpose. AliAmjad(MCP)

The question isn't valid. You don't connect to the bus, you have to talk to a device connected to it using the devices SDK, or some other "generic" method, depending on the device you want.

I have written two articles on this. They are the only way I know of doing it and it requires a msi file to be created and then an admin user must run it on each PC that needs to access the program on the network share. http://www.codeproject.com/dotnet/Using_MSI_or_a_strong_nam.asp[^] http://www.codeproject.com/dotnet/Using_MSI_or_a_strong_na2.asp[^] Hope that helps.

I thought this question sounds familiar. Asking it again and again and again, won't change the answer[^]. A guide to posting questions on CodeProject[^] Dave Kreskowiak Microsoft MVP Visual Developer - Visual Basic      2006, 2007

You asked this yesterday and were given the correct answer. You have NO CHOICE but to read up on and understand Code Access Security[^]. You're getting this exception because code executed from an non-local (read: network) source is NOT TRUSTED and runs in a heavily restricted sandbox. You have to tell the machines running the code to trust the source of the code to get more permissions.

Never tried that but wouldn't you need to generate your DataSet from the Master file?
