hi there,

I just want to explain my problem. There is an application which is coded by
me running. It is an vb.net application having user controls windows forms
and something like visual components. Also i can send some command line
options from the command line

for example >> C:\xxx.exe -a

i can run this application without command line options also, however every
call of the xxx.exe create a seperate windows form and display it on the
desktop. I want to run this application many sequantial times with command
line options without creating many windows form but new command line options
process...

I mean

xxx.exe -a "Something"

while previous one is running

xxx.exe -a "Something Else"

will do something else...

xxx.exe has list box... first run is add the "Something" text into the
listbox and while it is running, the second run is add the "Something Else"
text into the same listbox under the "Something" text.

how can i success this?

Hi,

Use a mutex. Start the program from sub main

Public Sub main()
Dim owned As Boolean
Dim mut As New System.Threading.Mutex(True, "xvcjsdf67AS124#$3",
owned)

If owned Then
Application.Run(New Form1)
mut.ReleaseMutex()
Else
MessageBox.Show("A previous instance is already running")
End If
End Sub
