I'm new to this form and don't normally program in C# I'm more SCADA/PLC/VB guy and could really use some help.
I'm currently working on an HMI panel running a Beijer iX application in WinCE 6, the app uses C# for its scripts.
My problem then,
I have to send a data string (using an RS232 port) to another computer (survey spread on a cable lay ship), the string needs to be made up from various tags from the HMI tag database.
I can access the COM port and send data out, but only from a screen button and I really need to setup a 1 second timer for this and so far I cannot work out how to build the string to send.

I have written this very program in VB a long time back but so far C# has got me stumped

Any help/pointers would be greatly appreciated

Thanks

See http://msdn.microsoft.com/en-us/library/system.timers.timer%28v=vs.71%29.aspx for help on timers. Not sure what your question is about strings..... look up the StringBuilder class, I guess.

The best way to achieve that is to use SerialPort[^] class, with its several methids, properties and events.

Example in C#: Serial Communication using C# and Whidbey[^]
Basic serial port listening application[^]

Example in VB.NET: http://msmvps.com/blogs/coad/archive/2005/03/23/SerialPort-_2800_RS_2D00_232-Serial-COM-Port_2900_-in-C_2300_-.NET.aspx[^]

To send/receive data in a period of time, use timer[^] class, example: How to use timer control in C#[^]
