B4J Question Filechooser how to detect Cancel click

[ThRuST]

Hi I wonder how to detect cancel click in filechooser? I tried this

Dim fc As FileChooser
fc.Initialize
Dim filename As String = fc.ShowOpen(MainForm)

If fc = fx.DialogResponse.CANCEL Then
    ' code
End If

Thanks,
ThRuST

filechooser will return an empty string wheter it was cancelled or the user did not choose any file.

Nice answer. Now why didn't I think of this myself Thanks

And for all the lamers out there that is new to programming here's the solution

Dim fc As FileChooser
fc.Initialize
Dim filename As String = fc.ShowOpen(MainForm)

If filename = "" Then
' No file choosen

Else
' User choosed a filename

End If

That happens, its normal for us to overcomplicated ourselves,

watch out when you copy paste from the forums tags, they will mess the formatting, look at your 2nd line!
