Question

I recently had this idea to create a C# Windows Form App that enables a user to launch applications from there. This is my ‘raw’ code:

Button1 Click Event…

{                     

 System.Diagnostics.Process.Start("WINWORD.EXE");

} 

Button2 Click Event…

{

System.Diagnostics.Process.Start("WINRAR.EXE");

}

.
.
.
.
.
.

and many more …

Can anyone please tell me what the code is in case that handles the event in case that an application cannot be found(ex. WINWORD.EXE is not available blah, blah blah)?

I tried using the ‘if-statement’ but to no avail, I get compilation errors.

Can someone help me out? How can I create a function that lets the user add some application shortcut to the C# app?

Thanks to everyone in advance.

I would just put your call to launch the app into a try...catch... block

Button2 Click Event…

{
   try 
   {
      System.Diagnostics.Process.Start("WINRAR.EXE");
   }
   catch(Exception exc)
   {
       // handle exception, e.g. possibly log it to a file or database, or do something else
       MessageBox.Show(exc.Message, "Error occured", MessageBoxButtons.OK, MessageBoxIcon.Error);
   }
}

In this case, no matter what goes wrong, you’ll be able to catch that case and at least show a message to the user – of course, you might want to “tweak” that message a bit …..
