Interrupt Function?

Hi,

I am passing a collection of filenames to my business layer, which then copies the files from the paths specified in the collection to another location while creating entries in the database.

If the file already exists at the new location, is there any way to Interrupt the function and ask the user if they want to replace the existing file and then continue the operation?

Any help will be great :)

You could do that by using the FileInfo class.

In your function, create a variable like the following:

VB Code:

Dim fInfo as New FileInfo([i]FileName[/i])

Then to see if the file exists, do the following:

VB Code:

If fInfo.Exists = True Then
    If MessageBox.Show("File exists. Would you like to replace?", "Prompt", MessageBoxButtons.YesNo) = DialogResult.Yes Then
        'Code to replace
    End If
End If
