I have the below VB loop. I need to put the index i into the loop statements so that the expression will execute for every text box. I continue to get method argument and declaration errors on this. I'm so used to coding this in C++ that I am unsure how to convert to VB.
Dim i As Integer = 1
For i = 1 To 32
PG[i]NoBox.Text = "1"
Next i
ASPX Page:
<asp:ListView ID="lvSubjects" runat="server" >
<LayoutTemplate>
<asp:PlaceHolder ID="itemPlaceholder" runat="server" />

Where am i going wrong?? i do not get any error...but this code is not working for me.
Currently I have a problem with updating my database with values in my Data Grid View.
On my form I have a "Populate" button and "Submit Details" button.
The "Populate" button fills my Data Grid with numerous lines of data.
On the click event for "Submit Details" I want this data to be inserted into a table in my DataBase by looping through each record.
For Each dgi As DataGridView In DataGridView1.Rows
Dim productCode As String = DirectCast(dgi.FindControl("product"), Label).Text
Dim description As String = DirectCast(dgi.FindControl("description"), Label).Text
Dim quantity As String = DirectCast(dgi.FindControl("order_qty"), Label).Text

I need to find a method of looping through a listbox and retrieving the index number and values - quite straightforward in asp, but turning out to be something of a nightmare in winforms!Here is the scenario - The user can add values in a textbox, that are in turn added to a DataTable that gives it a unique ID and a row number, this is then bound to the listbox. The user can then move the items up or down the list by adjusting the row number in the datatable and rebinding to the listbox..
The problem that I am hitting is when the user needs to delete an item -the first part is easy - delete from the DataTable and rebind to the listbox. The bit where I hit the proverbial brick wall is needing to loop through the listbox rows and getting both the index number and the ValueMember - that way I can change the row numbers in the DataTable based on the index number against the ID number.
If i try
ListView1.Sorting = SortOrder.None
ListView1.ListViewItemSorter = Nothing
ListView1.Items.Insert(0, "0")
ListView1.Items.Insert(1, "1")
ListView1.Items.Insert(0, "2")
ListView1.Items.Insert(1, "3")
If ListView1.View is SmallIcon , LargeIcon or Tile it dont work (Display 0 1 2 3). If it's in List it works (Display desired 2 3 0 1).

What I'm trying to do is monitor a file and if it exists then then copy it's contents to a database, then delete the file. Currently it only adds the data one time and does not delete the file.why it will not keep adding the data or deleting the file?
i know there are no "control arrays" in vb.net. i do come from vb6, and im trying my way now within bv.net, so please be gentel...
if someone could please post a simple code to do the following, it would be great:
i have 3 textboxes called txtBet1, txtBet2 and txtBet3.
i have another 3 texboxes called txtResult1, txtResult2, txtResult3.
so i want to have one loop code, to get the value in txtBet1, calculate somethings, and put it into txtResult1.text.
i know it's basic, but i tried using this sample here as a reference, but its not really understandable for me, because its not really choosing the exact control i want to address...
this is from Microsoft website - a comparison between vb6 and vb.net:
"' Visual Basic 6.0

Okay, so basically I'm trying to have my application randomly select items from a (multiselect) listbox. I want the user to enter the amount of items they would like randomly selected and it should all happen at the same time. I have the random shuffle down but it only selects one song each time you click the button. How can I loop this code as many times as the user specifies in the textbox?
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As
Dim shuffle As New Random
Main.songlist.SelectedIndex = shuffle.Next(0, Main.songlist.Items.Count - 1)

Well I'm working on a kind of GameGuard for my private server. Ok so, I want to loop a code, I dunno if I should use Console or Windows Form Application...I dont know how to explain but I'll try doing my best to make this understandable. Ok so I want to make something that will loop this code until the console itself is closed. This code below would simply kill the windows name "Cheat Engine" program if its opened.[code]But If I use a console application, How can I make this code loop every 5 second or so? What would I need to add in this simple code to make it loop every 5 seconds and until the console is closed?

I am trying to create a way to use my arrow keys to move around some text boxes. The form has 12 textboxes moving from left to right with 4 in each row. Tab Index will be like this.
0 1 2 3

8 9 10 11
In the code I have figured out how to find the current tab index but I am having trouble moving to the next control based on which arrow key is pressed. Here is the code I have so far.

I commented the area where I haven't been able to figure out how to code it. I have spent a few days working this out and have spent the past 6 hours working on this part.
I have the following

Private GIFAnim As Image = Image.FromFile("c:cointosscointoss_ani.gif")
Private frames As Integer
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
[CODE]...
Now I would like to put a wait in after the line:
frames = GIFAnim.GetFrameCount(Imaging.FrameDimension.Time)
ImageAnimator.Animate(GIFAnim, AddressOf paintFrame)
This is so that the animation has time to play and stop and then the rest of the code will display the other picture and the numbers. Is this possible? I tried timer and sleep but I cant get them to work.
