Looping Through Different Textboxes With One Loop Code
Jun 1, 2010
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
Private Sub ClearText()
For i = 0 To Text1().UBound
[Code]....

Dim i As Integer
For i = 1 To 10
If TypeOf Me.TabPage1.Controls(i) Is TextBox Then

End If
Next i

I have the following code:
For Each control2 As Control In GroupBox3.Controls
If TypeOf control2 Is TextBox Then
Dim txt2 As TextBox = TryCast(control2, TextBox)
If counter > totalBoxes Then
[Code]...
What I am doing is looping through each textbox in groupbox3. Then checking if the counter(total number of grades that are inputted in the form) are greater than the totalBoxes(which is set to 0) and finally I am putting the actual grade(A,B,C,D) into the textbox. The problem is that it is starting the loop at textbox 8(I have 10 textboxes) for some reason and going from there. Does anyone know what the problem is with my code?

I'm making a rock paper scissors program and once I set the current_scene variable to 1, the MainLoop() sub doesn't keep looping, but the sub doesn't exit either. (Form1.vb is the most important file.)

I am looping through a database with pdf locations. The application is button click event driven. The problem I am having is that I display a pdf. If the user clicks on the button then the pdf information is inserted into a database and the loop should be taking me to the next pdf. However, this loop does not seem to give what I need. What ends up happening is the first pdf gets displayed twice. I think mainly because I display the first pdf onload, but when I click the button it agrees and grabs the first item from the database. And it ends up falling behind because its restarting the query and I cant quite figure out how to get the button to catch the first displayed pdf, or skip it entirely since I am using a welcome pdf. So on the welcome pdf that is supposed to be displayed initially the user clicks agree and it agrees to the welcome pdf instead of just skipping it. I am not quite sure how to just move past the pdf.
public sub onload()
display the welcome pdf
end sub
[CODE]...
Now if I run the code without the loop it works fine. I just end up having to run the app however many pdfs I have in my database.
query data
display data
insert data
Windows.Forms.Application.Exit()
To display pdfs I imported the com control for adobe so pdfs get displayed like this:
axacropdf1.src = my.mysettings.default.readpath & pdflocation
pdflocation is passed from a query fill.
I think I have an underlying design issue which probably precedes the loop.

Im working on a console application, and i need my application to open message boxes without stopping/interupting/pausing the loop. I have been trying to make it open another application which spawns the messageboxes, but then every message box comsumes ~4MB RAM which becomes a problem when to many gets opened.

I'd like to make a simple program where my form consists of a textbox and a button. Here's the ide in a nutshell:in form1_load I invoke the sub:
private Sub LoopingLesson()
dim i as integer=1
while true
[code]....
what I want is when i hits certain value, like let's just say i is divisible by 365, then the 'while' looping will stop, and a message box saying "target reached" appear. then after I click button1, the looping will resume until it reaches the next number divisible by 365, and so on.

Trying to write my program in vb.net 2010. I have read my 2 books and have been playing with the code a bit. Got streamreader and writer and My Namespace understood as far as text files go. Now I'm trying to get all my textboxes in tabcontrol tabpage1 to be cleared of text thru the For Each loop.
I've tried various ways and keep getting invalidcastexception error. I even changed the tabcontrol and tabpage modifiers to public. That did not work either.
[CODE]:....................
I thought the code would not only clear all textboxes on tabpage1 but on all the tabpages. The help tells me that "When casting from a number, the value must be a number less than infinity and to make sure the source type is convertible to the destination type. I have three tabpages and that is definitly less than infinity. The source type and destination type puzzle me a bit.
Here is what I got using intellisense, however it not only clears the textboxes of text on tabpage1, but it clears the labels and buttons of text too so it is not a perfect solution.

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

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?

So I'm running a For loop that creates a ThreadPool thread and executes a task. Once the For loop finishes, I'd like it to "start over" and do the same thing. Now this obviously causes an infinite loop if I don't do it right.
what I'm kind of wondering is; is there a way to "keep" those threadpool threads active and constantly performing a task? it seems like they get disposed of once their "task" is complete.
Right now, the thread connects to a webservice, captures some data, stores it in a List(of String). This ultimately builds a ListView with the data. One of the columns is a "count" and i'd like to keep updating that count continually.
