[PrakashBhaskar]

Hi, I have created a windows application using VB.NET its working fine there is no issue on that applicaiton. My problem is i want to restrict multiple times of running the same application. for example if i click and run the exe file it will open the application again click on the same exe file it will open the same application second time. I want to restrict that if u click on the exe n time it should open one not many. is it possible if so can u plz guide me how to do that.

Hi You can iterate though the processes running on the machine to see if one is running with the same name as the current application. Code would look like Dim currentProcess as Process = Process.GetCurrentProcess Dim allProcesses as process() = process.getprocessesbyname(currentProcess.ProcessName) For each process as Process in allProcesses If process.Id = current.Id then continue for If [Assembly].GetExecutingAssembly().Location.Replace("/", "\") = currentProcess.MainModule.FileName Then 'There is another version running Throw new exception("Application already open") end if next Thats just entered but should give you a good idae of how to code this...

run this on Form1_Load If (UBound(Diagnostics.Process.GetProcessesByName(Diagnostics.Process.GetCurrentProcess.ProcessName)) > 0) = True Then End End If
