Need Help with Shell

[Jack Russell]

Why doesn't the following code run acrobat?
It throws a file not found exception

Thanks

Dim s As String = sgAppPath + "TCW3Help.pdf"
Try
If Not File.Exists(s) Then
MsgBox("Cannot find " + s, MsgBoxStyle.Exclamation)
Else
s = """" + s + """"
Shell(s)
End If
Catch ex As FileNotFoundException
MsgBox("Unable to open Help file " + s + " check that
Acrobat is installed", MsgBoxStyle.Exclamation)
Catch ex As Exception
ReportBug(ex, "Trying to open help file " + s)
End Try

Try this:

Dim s As String = Application.StartupPath & "\TCW3Help.pdf"
Try
If Not IO.File.Exists(s) Then
MessageBox.Show(String.Format("Cannot find {0}", s),
Me.Text, MessageBoxButtons.OK, MessageBoxIcon.Exclamation)
Else
Microsoft.VisualBasic.Shell(s, AppWinStyle.NormalFocus)
End If
Catch ex As IO.FileNotFoundException
MessageBox.Show(String.Format("Unable to open Help file {0}.
Check that Acrobat is installed", s), Me.Text, MessageBoxButtons.OK,
MessageBoxIcon.Exclamation)
Catch ex As Exception
MessageBox.Show(ex, "Trying to open help file " + s)
End Try

I hope this helps

Thanks but still get the same thing, exception on the shell command.

Any other ideas?

I changed the filename to one on my system & it worked for me. Just play
around with the Try Catch End Try block.

Sorry, but I don't have the time to do anything else for the next 3-4 hours,
but later if you don't have a solution then I'll re-write it for you.

Jack,

Did you try it already with Process.Start(filenme)
(Needs a reference to be set).

Pdf, should of couse start when you click in explorer on that, otherwise you
have to name the program in this method as well.

In addition when you try something, set than first the hardcoded path in it,
that makes finding an error much easier.

I hope this helps,

Cor

Dim s As String = Application.StartupPath & "\TCW3Help.pdf"

=> 'System.IO.Path.Combine'. Otherwise the path will contain two
backslashes if the application is installed to a drive's root directory.

Cor,

Thanks that worked!

 

[Jack Russell]

Thanks, still no joy but took Cors suggestion and used process.start -
no problems.
One thing I can say for .net, there seem to a thousand ways of doing
anything and one eventually works!

I just recoded your solution because that's the way you wanted to code it.
Process.Start is an easier way, I agree
