Program That Will Compare Array Of Grocery List Items Glist And Array Of Coupon Item List
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. [code] The code seems to work great until I come to the else statement.When the code finds a match it displays the picture box and the msgbox without error, but as soon as the message box is cleared, even though i've input it as an ELSE statement, the picturebox goes false again.Does anyone have any idea of how I can "hold" the picturebox to stay visible while the match between the arrays exists?

Getting ListView Items Into Array
Sep 21, 2009I have a listview with two columns of data in it. I want to capture all the items in the listview into an array. The array will have two dimensions, one for column 1 and the other dimension for column 2. I am a little lost on how to iterate over the listview items. I figure it would be a for each statement. Its also the actual call that passes the found item and sub item to the array I am struggling with.
View 2 RepliesHow To Get Random Items From Array
Aug 26, 2010I have an array with 280 items in it. I only want 140 of those, so I want to pick them at random. So I need to generate a random number between 0 and the source array's getupperbound property. I think. Is there a more suitable way to pluck an item from an array. I wonder if there's a way to ensure that you don't choose the same item more than once. I suppose I could randomly sort the source array and choose the first 140 items, that would ensure I don't get a repeat item. But could be inefficient if the source array is much larger than the destination array, because I'd be shuffling more values than I need to shuffle. I suppose it's a sampling problem.

Array Of Dropdown Contextmenustrip Items?
Jul 21, 2009I am trying to build a context menu for a little "random quote" generator project. Most of the context menu for the NotifyIcon I can create at design time, but I need to create a submenu of file names that the user can choose (check) to be included in the quote population.
I originally did this in VB6 and it worked, now I get a Null reference error. The problem occurs in the Sub BuildChooseFilesMenuItems. Code follows. (Basically, I need to read in the filenames, make them menuitems and keep track of their "checked" state. It is dynamic because the user could add new quote files to the directoryy where they are stored.

MyArray(2) = "salt!"

View 9 RepliesUsing An Array To Insert Items Into A Textbox?
Apr 27, 2011I am having some trouble splitting a string within an array into 2 values. For example in my textbox I have several lines of measurements that are Length x Width: 20x14, 10x8, 16x13. Each measurement is on its own line. I'm trying to split all Width values that are greater than 12 into 2 separate measurements, so with that last example, I would have 5 measurements (LxW): 20x12, 20x2, 10x8, 16x12, 16x1, then I would like to add these measurements to a new textbox with each measurement on its own line.
Here is the code I have so far. Again, I am very new to programming and this is the first serious project for me since "Hello World", so what I have might be way off. Thanks in advance.
