Script - Create A New Textbox Eachtime Without A Loop?
Jun 17, 2010
My script should Read order numbers and for each read loop create a text box and populate it with the value, then loop again and put the next text box below with the next line orderno.... (just to make it fun it has to dynamicaly create its own box for weach loop to sit in)however it only does 1 loop.
Dim oCmd As SqlClient.SqlCommand
Dim oDR As SqlClient.SqlDataReader
Dim strSQL As String
[CODE]...
Is it because i should be skipping to the next row and not looping, if so how can i create a new textbox eachtime without a loop?

I have a button and text box. Every time I click on this button a number increments in the text box (textbox1). So far so good. Also on the form is another button called 'Submit' and three more textboxes. (textbox2, textbox3 and textbox4) What I want to do is every time I click on the submit button the value in textbox1 will be placed in the first textbox (testbox2) I will then increment the value in textbox1 and then hit submit again and the current value will be placed in textbox3 etc. The question I guess is how do I create a for - next loop that will increase the textbox?

I have most of the coding done, but i don't know how to code my hangman program so that when you enter a wrong letter, a picturebox image would appear eachtime. Also i want to put a limit on the amout of guesses you can have. If possible, i would also like a listbox with the letters that you have guessed wrong stored in it.
Here is my code so far:
Imports System.IO
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

So I made a simple patform game where the player has to jump quickly while the platforms move to the bottom of the screen, as to not touch the bottom of the screen. But, I need to know how to create a loop to loop the locations of the platform. This means that after twenty or so platforms, the same platforms come up again, so that the player will have an "endless" game. I've declared all the platform's locations relative to the location of the first repeating platform:

I've been looking far and wide to find the answer to my question. Its probably has a simple answer, but I am new to VB2008 and can't figure it out. I have a web form setup 30 textboxes, and am trying to find a way to quickly add them to an array through a loop.Their ID's are all - TextBox1,TextBox2 ect. I have this loop here that runs with no errors, but nothing shows up in the TextBox's on the web form.If the TextBoxes are already on the form, do I still need to declare new boxes when trying to add them to the array?

Im trying and failing to do the following: I have 90 textboxes named N1, N2, N3, N4 etc. I am generating a random number from 1 to 90 on the press of a button. If 1 is the number randomly generated then i would like the textbox N1 to to change its behaviour for example change background color. Apart from a Massseeeeeev if statement is there no way to loop through all these textboxes until the number generated matched the number in the name of the textbox? In VB 6 i used a control array so N(1), N(2), etc.

seriously struggling with this one bit of a program im creating. Im trying to simulate a moving queue, using a number of pictureboxes (controlled by Timers). Once a picturebox vanishes, another appears in front of it to symbolise movement throughout the queue.Anway... Im struggling with LOOPS! I cant seem to make the funtions repeat and I need this urgent due to a deadline in 16 hours time Background Info: The form will run for 60 seconds, after which anotehr form will loads (MorrisonsQueueSummary).Here is the syntax so far:vb.net

Is it possible to create a loop using a string I am writing a program and I need it to output 3 letters ahead of the letter you input for instance if you input a then it outputs d and if you input u it outputs x, and also the same with capital letters A then D U then X and so on. I have writted the program the only problem is that when I input X I want it to output A but it outputs [ instead I need to create a loop where when I input X it starts the alphabet over again, and I need to know if it possible and if so how will I go about doing so.

Makes the following statement about the code below:
**"The computer evaluates the loop condition in the Do...Loop statment to determine whether the loop instructions should be processed. In this case, the inputsales <> String.Empty condition compares the contenst of the input sales variable to the String.Empty value. As you know the String.Empty value represents a zero length, or empty, string if the inputsales variable is empty, the loop condition evaluates to True and the computer process the loop instructions. *If on the other hand the inputsales variable is not empty, the loop condition evaluates to false and the computer skips over the loop instructions.
Based on the code I think it is the opposite: ...that while the inputsales value is not empty it should evaluate to true and process the loop and if it is empty it should evaluate to false and skip the loop?
See below.

Option Strict On

I'd like to create a loop that dupliates a label I've made and put it all over the screen. Example of what it would look like.
For i = 0 to 52
originalLabel.duplicate ("duplicatedLabel" & i)
next i
So later I could go through all of them...
For i = 0 to 52
//... some logic to determine color... then assign it somehow
duplicatedLabel & i.backColor = Color.red
next i
[code].....
I can do that in Flash/Actionscript but dunno how to do it in VB and I can't find it anywhere.

I've got an app working semi-background stuff in the GUI thread. Another thread won't work and a timer won't work. But I want the app to be responsive while I'm going my 'background' work.I cound use application.doevents - but that gives me 3 bad choices:
-loop with no sleeps - end peg an entire CPU (my task waits on stuff besides calcs & I/O so this matters)
-loop with a sleep - then the app slows down
-Try to make a 'smart sleep' loop that speeds up when lots of messages happen (check for messages in messagefilter function)
[code]why I can't use application.run, or threads, what I want to do is handled the OnUnhandledException event, then leave my app open for a while while some winforms stuff closes it down gracefully and tells my watchdog program to restart the app. after allowing the user to finish a critical process, too. Yes, I know people thing that a program getting OnUnhandledException deserves to die (obviously MS), there are 'dangerous' things that could happen; none of them are as dangerous, however, as the wrath of my users. Looking for vb.net sourcecode exact translations of the above two functions.

threads that watch folders and process files. This works fine, but every time needs change to add a new folder or just change some existing rules I have to go in and change the program. I want to builda front end that storesprocessing infofor each watchfolder. The program would then read the configs and build the threads based on them. I cannot find a way to loop through creating the threads.

I have a string where I have created a template so to speak.
{
Dim myvariable as string
Richtextbox1.text = Richtextbox1.text & "The dog jumped over the" & myvariable & "to find the fox."
}
I have a list box that contains a list of options that loads into the variable example: fence, bucket, etc.
So the sentences would read like
The dog jumped over the fence to find the fox The dog jumped over the bucket to find the fox
Right now I have it coded to display into a rich text box but everything is in the same rich text box.
I'm trying to load the string into an array at the end of each loop this way I can then have each sentence separated.

I have a VB.Net 2005 project, that has 136 textboxes. I have a button, that when pressed, should copy all of their content to clipboard. In order. Each Textbox has one letter in it.
Is there a way I can implement a loop into it, so for every TextBoxCount or something, it copys it into clipboard?

I created a new thread to run with a loop to update a textbox (this is just a demo, in reality this thing would go out to a db every x minutes to request an update). I did this on a timer, but i wanted to try to do it on a different thread.. anyways, this is what I have: (one form, one textbox, and this code...)[code]I'm getting a warning through (the "Thread.CurrentThread.Sleep(2000) part is underlined) which states:"Access of Shared Member, Constent Member, enum Member, or Nested Type through an instance; qualifying expression will not be evaluated".

I am trying to understand the do until loop when adding numbers along with a variable to a new line in a textbox, incrementing each time. My current example is very simple but only returns the first value. I require the output to be incremented automatically, so I thought a do until loop would be best.

I would like to show that the computer is busy and not frozen during a long file transmitted over Serial Port.I have the following loop.The intention was to show one "*" for every line sent.
While (fs.EndOfStream = False)
lineRead = (fs.ReadLine)
TextBox1.Text = "* "
SerialPort1.Write(lineRead)
End While
I can see the data sent on the Scope but the chain of "******...." show up after the transmission ends.The WHILE LOOP is actually working but the TextBox1.Text = "*" is not writing to screen.I would like to see the train of ******** same time as the transmission is active.The * is to show that the computer is busy and not frozen.Writing a copy of the actual serial data transmitted to screen is also another option that I can use.

Windows Forms, VB application... Forgive me in advance for this very elementary question but I am overlooking something really simple here. I would like to have a label show the current value of a variable as the for each loop runs.. I created a very simple Button Click event to figure out where its failing. As it is right now the value does not display until after the for each loop finishes running, which it should actually display the counter value each time it runs through... I know this is possible and really simple because I did it years back but for the life of me cant figure out why I am missing the bar as it should constantly update the label to reflect that?Test Sub is as follows:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim counter As Integer = 0
For x As Integer = 1 To 200000
