I have Label (Label1) and a button (command1)

The caption for label1 is "0"

When I click the button the label will add "1" each time I press the button...
So the labels continues 1, 2, 3, 4, 5, ... and so on...

Now let's say that I have reached to number 21 and I regret that last click.
How can I create an undo button? Let's say we create another button (command2) who should do the trick.

it will be the same code for adding one to the label but you will be taking one away.

that will only work if the numbers are done in sequence. what if he wants text? or random numbers?. i think you would have to store the information/numbers in some sort of variable as the user types them, not sure.

stevo

in the case of random numbers or different text then yes you would need a variable to hold the caption but

If you want a "real" undo button, you could create a class with the info a single undo step needs, and put each undo step into a collection. That's what I do, and it works like a charm.

However, in this case, it seems like you can just decrease the value in the box by one...

I thank you all for your help!

I just ran into another problem...
I dont want the label to decrease so low that it turns into -1, -2 etc...

Then simply put an if...

You should really put your fantasy to a little more use here.
