Trigger for Cancel button in CommonDialog

VB5:
In the Programmers Guide I find this example for the CommonDialog control, when opening a file from the Open dialog:

Private Sub mnuFileOpen_Click()
  ' CancelError is True.
  On Error Goto ErrHandler
  ...

ErrHandler:
  ' User pressed Cancel button.
  Exit Sub
End Sub

However, this doesn't work for me. Here's my code:

On Error GoTo Hell
CommonDialog1.Filter = "Text Files (*.txt)|*.txt"
CommonDialog1.FilterIndex = 2
CommonDialog1.ShowOpen
sFile = CommonDialog1.filename
...

Hell:
  Exit Sub

The code stops, as usual, after the .ShowOpen call, but then it _continues_ even if I pressed the Cancel button. Is it any other way to know when the user pressed the button?

Two methods - one is to use the commondialog box made by the ccrp
http://www.mvps.org/ccrp/

The other is to insert this line
On Error GoTo Hell
CommonDialog1.Filter = "Text Files (*.txt)|*.txt"
CommonDialog1.FilterIndex = 2
CommonDialog1.CancelError = True   ' **** insert this line ***
CommonDialog1.ShowOpen
sFile = CommonDialog1.filename
.

Hell:
  Exit Sub

Thanks. Can you tell me, what's the difference with the ccrp common dialog box?

The ccrp common dialog box adds several extended features.
-You can add controls to the dialog box (ie. a picture box for a preview)
-It returns whether or not the cancel button was pressed
 (if ccrpcd.DialogCanceled = True Then exit sub)
-You can change the captions on the OK and Cancel Buttons
-It returns an event for when someone changes directories
-It is positionable on the screen (x,y coordinates)
-It comes in an ocx of about 130k, so if you only need the common dialog box, you don't need to include all 500k of comdlg32.ocx, but just the ccrp ocx.
-There's a bunch of other stuff too, but I can't remember it all.
