Adding Variables Of Array To List Box?
Sep 2, 2010Ok so I have an array and wish to add the variables of the array to separate lines of the list box. I came across this which in some ways worked but also didn't. The second thing mentioned on the page was to us:
ListBox1.DataSource = Form2.Title This works the first time you run it but if you try to run it again nothing happens. So using the above or something else how can I get it to update the list box? Another thing I tried was to use the DataSource method but instead to clear the list box first, but that turned up an error

Multi Column List Box Array Resets Before Adding Next Values
Mar 13, 2010When I implement this code, the first time the button is activated, the values are placed in the array, and displyed in the list box. However if the user then selects more days and times to add to the list box, and activates the button again, the previously added entries in the array are erased, and only the new entries are displayed. How can I prevent previous entries from being erased? If the user wants to add values, they need to be added to the existing values.[code]

The only thing I can do for now is either use the substring function to remove the first character from all array values after 0 but I don't like that because it's messy and what if the split "works" as I want it to one one of the lines and knocks of the first character when I don't want it to.

May 27, 2012I have a program that will compare an array of grocery list items glist and an array of coupon item clist.When I compare the two and if there is a match somewhere in the array I want to have a picturebox visible.When there is no match, I want the picture box not to be visible.
