OK... it's not very good C# code but I ended up using the following code in a console application.

//Compare seconds
starttime = DateTime.Now.Second; // Get current recorded seconds from system
while (starttime == DateTime.Now.Second) { }// compare the recorded seconds to the system seconds
// and continue to loop until the seconds are different

My application writes some text to a textbox then I will call a 1 second delay (1000 millisecond) then write different data to the textbox. I'm probably lacking the fundamentals on how to call functions (methods) in C# and where to locate it in the files/classes. In C I would create the function prototype and the function and then call this function within main(). Calling the function on the form isn't the issue... it's how do I add this function (method) in to my Visual studio 2008 C# Windows form application. Any clues would be appreciated. Joe

Please tell us more information about the mobile phone you will use. Does the mobile phone have a a serial port or USB connection? General information on GSM/3G AT commandset is available here http://www.developershome.com/sms/howToUseHyperTerminal.asp[^] For Serial port operations in C# look up SerialI/O in MSDN Reg Joe

Hi All, I have a very basic windows applications form working. I would like to add this public function so that I can call it in the form code. public static DateTime PauseForMilliSeconds( int MilliSecondsToPauseFor ) { System.DateTime ThisMoment = System.DateTime.Now ; System.TimeSpan duration = new System.TimeSpan( 0, 0, 0, 0, MilliSecondsToPauseFor ) ; System.DateTime AfterWards = ThisMoment.Add( duration ) ; while ( AfterWards >= ThisMoment ) { System.Windows.Forms.Application.DoEvents() ; ThisMoment = System.DateTime.Now ; } return System.DateTime.Now ; } Where do I paste this function so I can call it on the windows form. How do I add files with functions to my code.... do I have to encapsulate them in a class? Thanks in advance Joe
