Using An Array To Insert Items Into A Textbox?
Apr 27, 2011
I 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.
Dim room As String = RoomsTextBox.Text
If room.EndsWith(vbCrLf) Then room = room.Substring(0, room.Length - vbCrLf.Length)
Dim roomarray() As String = room.Split(vbCrLf)

So the on this application a user will click a workgoup then a location then when they add the workshop it will and the prices to gether and put them in the lstCost, while doing that it also puts the price in the lblTotalCost.Text. Now the problem I am having is when a user adds more then on workgroup and location the lbltotalCost is geting what ever the last line in the lstCost is and multiplying the last line by the index number that it is so if the last line is line 2 then it will * 2 for line 3 then *3 of what ever the price is. Heres what I have so far...
Option Strict On

Dim intSubTotal As Integer
Dim intCount As Integer
Const intHANDLING_STRESS_DAYS As Integer = 3

I 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?

I wanted to simply on click a button to add those newly created textboxes to an array of textboxes. Starting with those labeled "Address". But I am finding this very difficult. I am able to add those originally on the form into the array very easily. But am unable to add the newly created textboxes into the array.
Here is my code so far below.

I have a lot of control array textboxes called txt(1) to txt(320) on form2. I have a textbox1 on form1 with a click evet that says textbox1.text= form2.txt(1).text but it gives an error (txt is not a member of form2). I tried disabling option explicit, option strick and option infer. Still won't work. My code is to long for this place maybe a short version osf the code. Do I need to make a Public MyArray(15,15,15,15) as string, in the Module1 then copy txt(n).text to the array or is there a way to access txt(n).

I 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.

I 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.
