Closing a process problem

[kservice]

Hi There,

 

I have searched this site for "closing processes" and found some great stuff.

 

I copied and changed some code that I found and have come up with the following function.

 

Public Function PrevInstance() As Boolean
       Dim processes(), p As Process

       Try
           processes = Process.GetProcesses()
           For Each p In processes
               If Not (p.MainModule Is Nothing) Then
                   If System.IO.Path.GetFileName(p.MainModule.FileName).ToLower() = "winword.exe" Then
                       p.Kill()
                       Exit For
                   End If
               End If
           Next p
       Catch ex As Exception
           Throw
       Finally

       End Try

   End Function

 

The problem is that it works great if it finds what it's looking for. If "Word" is not running than I get the following error:

 

Run-time exception thrown: System.ComponentModel.Win32Exception - Unable to enumerate the process modules.

 

I hope it's just something small that I'm missing.

 

Thanks for your time.

you could just change the line that reads

throw

to something like

MessageBox.Show ("Process not found")

to stop it crashing out. However if you step through the code in the debugger which line is the one it fails on?

It fails out on the line:

 

If Not (p.MainModule Is Nothing) Then

 

It's like it doesn't know it's reached the end of the processes or something.

 

Thanks

So I have stepped through it some more and at least can dup the error every time.

 

There are usually 26 processes running when I try this code and I get to process number 23 and it blows on "If Not (p.MainModule Is Nothing) Then".

 

Help? :rolleyes:

What is the value of p at this point - you may find you should be checking for if Not p is nothing

I got it! ;)

 

Thanks everyone

What is the exact problem. Can you please explain me?

It's been almost two years. I don't remember. :p Sorry!
