undo function 1

[231166]

Hi,

i would like to create a function which permits to a user to annul the last action he has done.
i had a lok on msdn but what i saw is not so clear :

if DTE.ActiveDocument.Undo Then

what is exactly DTE.ActiveDocument

Do i need abslolutely to use it for annuling the last function?

Could you help me on this point.

Thanks a lot for your help.

DTE has to do with macros. ActiveDocument refers to the current code window.

In my experience there isnt a way to undo as user's changes in Visual studio.

Hi,

If there is no way to undo changes in vb.net why does this function exist in the index of all the vb.net functions??

If your form consists of only textboxes here is a start.

        For Each ctl As Control In Me.Controls
            If TypeOf ctl Is TextBox Then
                CType(ctl, TextBox).Undo()
            End If
        Next

I looked and I didnt see an Undo function for the Me keyword, i saw an undo function for text boxes, and i didnt see one for checkboxes.

Where are you looking that you see an undo function for all functions.

You'll need to write a fair amount of code to support this in a generic fashion. Investigate the Command pattern for this.
