Capturing Dialog Response during CopyFile

[gixxer05]

I have an application that primarily moves files from one location to another. I need to get the user's response when asked by Windows if they would like to overwrite or rename the new file because it already exists in the destination selected on the form. I basically need to receive a boolean value so i can update the transaction logs. The function follows:

 This function handles copying files from one location to the destination specified on the form
    Public Function copyToNewLoc(ByVal source As String, ByVal destination As String, ByVal bln As Boolean) As Boolean

        Try
            ' Copies files, and shows the probress bar during the file move
            My.Computer.FileSystem.CopyFile(source, destination, FileIO.UIOption.AllDialogs)
            bln = FileIO.UIOption.AllDialogs
        Catch ex1 As NullReferenceException
            MessageBox.Show("A null reference error occured. Please enter both source and destination paths to the file(s).")
            bln = False
        Catch ex7 As ArgumentOutOfRangeException
            MessageBox.Show("An error occured: " & ex7.ToString)
            bln = False
        Catch ex2 As AccessViolationException
            MessageBox.Show("The application experienced an access violation error when attempting to copy the file.")
            bln = False
        Catch ex3 As DirectoryNotFoundException
            MessageBox.Show("The directory was not found.")
            bln = False
        Catch ex4 As FileNotFoundException
            MessageBox.Show("The file was not found.")
            bln = False
        Catch ex5 As IOException
            MessageBox.Show("An error occured when attempting to copy: " & ex5.ToString)
            bln = False
        Catch ex6 As Exception
            MessageBox.Show("An error occured: " & ex6.ToString)
            bln = False

        End Try

        Return bln

    End Function

All help is greatly appreciated. Thanks.

My.Computer.FileSystem.CopyFile is a sub and it is not return a value to tell what was the user response.

Even if that works as coded and I don't see any obvious errors, you still return nothing on your function. You need to return a boolean, eh?

Return bin

EDIT:=
NEVER-EVER MIND!
HEy, I did not scroll the window of your code all the ewway down.
I goofed.
My bad.

UH, so what's your problem?
USe Streamwriter and set to ovewrwrite and forget your Windows UI..

This line bln = FileIO.UIOption.AllDialogs will make the function return True when copying success, but there are two mistakes
1. bln = FileIO.UIOption.AllDialogs should replaced with bln = True
2. the parameter ByVal bln As Boolean has no meaning and must delete it.

OH, okay, I see the light brother

Thanks for the advice. I actually reworked my code to exclude booleans and dialogs from appearing when running the copyfile function. I have all exceptions issueing a failure string message that is sent back to the calling function, which updates the listbox log.
