Commands in Visual Basic #2

1) Combo Boxes – Allow the user to elect a value from a list in the box, or to input their own value. If the user does not need to input unique values, use a list box instead.

A) To add items to the box – Under Data – Items

Click on Items to get a box where you can enter values to add to your box

B) To use a value in the Combo Box : Just refer to : Combobox1.text

So that :

Label1.text = combobox1.text

OR

Label1.text = formatcurrency(combobox1,2)

2) List Boxes – will be seen as an array of choices. To access, they begin at index=0 and go from there.

*Note that you can also determine how many items can be selected:

Under Behavior: Selectionmode – None, One, Multsimple or MultExtended

A) To add items to the box

Click on Data-Items to get a box where you can enter values to add to your box

OR

Objects can be added to your box during run time using code – but these changes are NOT permanent. Most of these are also done using methods of the items, not the listbox.

Listbox1.items.add(text) -

Listbox1.items.insert(position, text) -

Listbox1.items.remove(“text”) Removes the first item that matches the text

Listbox1.items.removeat(position) – removes an item in a specific location

Listbox1.items.clear() – deletes all the items in the box

B) To use values in the box – depends on if you want to use it for a calculation

listbox.selecteditem – returns the string in the list that was selected

listbox.selectedindex – returns the index number selected

listbox.list(index) – returns the item at that location

3) Check boxes – You can check to see if they are checked or not, then make the decision in the code as to what to do.

Checkbox1.checked = true

4) Radio buttons – add to a group box. Then you can check which radio button is checked (if any).

if radiobox1.checked = true then
