Thanks

Process.Start("path_of_exe")

is what you want.

HTH,

'System.Diagnostics.Process.Start' or 'Shell' ;-).

 

[Mr. X.]

What is the difference between process.start and shell?

'Shell' is VB's way, 'Process.Start' is the method in the .NET
Framework. There are some small differences, but in general
'Process.Start' is more powerful.

One problem.
I did : process.start("myprog.exe")
but when returning the calling program, and trying do something I got the
message :
Unhandled exception has occurred in your application.
If you click Continue, the application will ignore this error and attempt to
continue ...

What should I do ?

Thanks

Post the complete exception information (which exception, additional
exception message, etc.).

OK, solved.

.... and about shell and process.start.
by command "shell" I can wait till I close the executable program (it may be
a modal dialog), and process.start doesn't have this option.
Besides, "shell" cannot send to the executable program arguments, and
process.start can.
I can use mutex & shell in order to send the executable program some
arguments.

Thanks

It has even more options, one of those is waitforexit but in your case
probably better to get the output content using the reader.

Have a look at those to get some examples

are you trying process.start on the testing machine?

you also have to put the full path process.start ("c:\program
\myexe.exe")

\\\
Dim p As Process = Process.Start(...)
p.WaitForExit()
///

I am pretty sure 'Shell' can actually do that. Did you try to include
the arguments in the path?

 

[Mr. X.]

It is true p.waitforExit() is waiting until I close the exe, which I have
called at the main program,
but if I click on the main program the button, which called the exe program,
several times,
computer "remembers" I have pressed the button, and hence when I close the
called exe program, the event occurs, and the exe is opened again.
same thing for shell : Shell("newApp.exe", AppWinStyle.NormalFocus, True)

If shell is the command line, then it's obvious that I can send parameters
within the command line.

Thanks
