Hello
How can i control, that a user can't start my VB.Net-Program 2 ore more times at once (maybee like Outlook)?
At same time Parameters which are transfered with the second program should be transfered to the first program.

If you are using VB2005, it's built in. Open the project's properties panel
(Project --WindowsApplicat ion1 Properties), select the Application tab,
make sure that "Enable application framework" is selected, and then select
"Make single instance application." To process the incoming arguments for
subsequent startups, click the "View Application Events" button on that same
panel. In the code file that appears, add an event handler for MyApplication_S tartupNextInsta nce.
In that handler, the e.CommandLine property gives you access to the new command
line.

This is what I use for VB.NET 2003:
#Region "Previous Existance Function"
' Previous Existance function
Private Function PrevInstance() As Boolean
' Check to see if another existance of the assembly is found
If UBound(System.D iagnostics.Proc ess.GetProcesse sByName(System. Diagnostics.Pro cess.GetCurrent Process.Process Name)) 0 Then
' Yes, it was - return true
Return True
' No previous existance found - return false
Else
Return False
End If
End Function
#End Region
Usage:
' Check for previous existance of the application
If PrevInstance() = True Then
' Display a message box if a previous existance exists
MessageBox.Show ("The application is already running. Press OK to exit", Me.Text, MessageBoxButto ns.OK, MessageBoxIcon. Error)
' End the application (see note at bottom of header above)
End
End If
I hope this helps,

Josh,
Rereading the excelent answer from Tim, if it is for versions before 2005 than is this in my idea the best result from endless discussion about this question on this board. http://www.vb-tips.com/dbpages.aspx?...6-343ac05a7617

Hi,
I have been looking into AOP (Aspect-Oriented Programming) for
sometime, now. I frankly don't like the syntax of any of the
approaches I have seen so far. I am kind playing around with some
ideas, and maybe write up an article later.
AOP is not just buzzword. It's not just callback, it's not just Ruby's
MixIn, it's not just Python's metaclass, it's not just C++'s template.
AOP can be implemented/considered as a subset of...

The function below is from Richard HeathField's fgetline program. For
some reason, it makes three passes through the string (a strlen(), a
strcpy() then another pass to change dots) when two would clearly be
sufficient. This could lead to unnecessarily bad performance on very
long strings. It is also written in a hard-to-read and clunky style.
char *dot_to_underscore(const char *s)
{
char *t = malloc(strlen(s) + 1);
