Listbox SelectedItem addition

manch

I need some help with this, just can't seem to get it straight.

I need to write a loop that will add each item of a listbox to get a Sum of the numbers inside.

I am using vb.net 2005

manch

Here is what i have so far...

Expand|Select|Wrap|Line Numbers

  intTnum = lstNum.Items.Count
 
        For intX = 0 To intTnum

            intTLoop = lstNum.Items(0)

            intTSum = intTSum + intTLoop

            intX += 1

        Next intX

How can i increment lstNum.Items(0) to the next number with each repetition of the loop?

Didn't test but this should work:

Expand|Select|Wrap|Line Numbers

 For intX = 0 To lstNum.Items.Count

    intTLoop = lstNum.Items(intX)

    intTSum = intTSum + intTLoop

Next 'intX this is optional

You're actually very close. Just two problems jump out at me...

lstNum.Items(0) should be lstNum.Items(intX)
The For loop automatically increments the counter (intX in this case). So by adding 1 to it again, you will be skipping every second item.

I'm going to split this question and my response to a new thread, just so they're easier for others to find. I'll come back and put a link here.

Ok, it's How to sum a 'column' in a listbox holding tab-delimited text
