[RESOLVED] Using Common Dialog box

Hai Friends
I am working with common dialog box. How can i find out the button pressed by the user( ok or Cancel)

If user pressed OK button .FileName property contents the file's path, if Cancel button, it contents empty string.

VB Code:

With CommonDialog1
    .Show
    If .FileName="" Then
    'Cancel button
    Else
    'OK button
    End If
End With

This is actually incorrect if the user opens more than 1 file. For example:

1) User opens Open File Dialog
2) User Presses Cancel
3) .Filename is empty.
4) User opens Open File Dialog
5) User Selects file
6) .Filename now contains filename
7) User opens Open File Dialog
8) User Presses Cancel
9) .Filename still contains the filename of the previous file.

To overcome this, the .CancelError property is useful:

VB Code:

Sub OpenFile()
On Error GoTo Err
With CommonDialog
.CancelError = True
.ShowOpen
LoadFile .FileName 'user pressed OK
End With
Exit Sub
Err:
'user pressed cancel
MsgBox "Cancel was pressed"
End Sub

chem

you can set .FileName property to empty string before run method ShowOpen or other

VB Code:

Sub OpenFile()
On Error GoTo ErrHandler
 
With CommonDialog
      .CancelError = True
      .ShowOpen
      If .FileName <> "" Then
          'do something with the file
       End If
End With
Exit Sub
ErrHandler:
If Err = cdlCancel Then
'user pressed cancel
Else
MsgBox Err.Description
End If
End Sub

thank you friends
but how can i handle other errors in that routine.Is there any specific error number for that error?

Keithuk's example shows you how to do this. Using:

VB Code:

If Err = cdlCancel Then

..checks if the user pressed cancel while using .CancelError.

The ErrHandler will show you other errors. If you don't press cancel and there is still an error MsgBox Err.Description ;)
