Re-Calculating and Saving

[kerenjamieson]

I have a form for inputting numbers and a Calculate button on the bottom of the form. (For information clicking the calculate button works out how much rope is needed to design Lifts).

Problem 1:

If I input the necessary numbers and click calculate it does the calculation BUT if I change any number and re-click calculate it does nothing, what's happening and how do I sort out?

Problem 2:

I have a list box of error margins - 0, 5 and 10% - on the same form.

Clicking calculate includes the error margin in the final calculation. If I save the file and then re-open it the error margin is back at o% and it doesn't show the usual error margin of 5% which is what I've been saving at. Why is it saving all the numbers in the other text boxes but not for this list box (is it because it is a list box?). How do I work this one out.

Hope someone can help as I'm pretty new to VB and I want to learn and carve out a new career.

Thanks very much

Keren

Hi,

You have to show some of your code for us to be able to answer your questions...
Problem 1: Make sure that your calculation are based on the values in the textboxes (f.eks. CSng(Text1.Text) and not on some other variable.
Problem 2: Set the .selected property of the item that sould be selected ( List1.selected(2) to select the 3rd item in the list). by the way - why not use a combobox instead?
