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.
I have a VBS script that allows me to do a recursive search through a specific registry key to find a key value in multiple of the key directories. And unfortunately it dosn't want to work properly with vb.net in my visual studio even when i try to make the syntax changes

I'm redoing a program I made up a while back and need some help changing a loop. The original program had all the text boxes on same form, the redesigned program still has them all on the same form but I have them spread across multiple tabs and the background of the form.
The code below loops through each possible text box and if it exists sets the value in an array. This only works for text boxes not on tabs. I found I could change the Me.Controls to TabPage1.Controls and that would get the text boxes on tabpage1. I would like to have a single loop that can find them on any tab and off the tabs, so I don't need three separate loops.
For num = 1 To 61 For Each controlctl In Me.Controls If controlctl.Name = "TextBox" & CStr(num) Then
I have a form with many buttons on it and I would like to loop through all the controls in a group control and find out which button is clicked.
I plan to use the click event of the button and I know it's easy to create a click event procedure for all of the buttons but would like to avoid that.
I am using datagridview to show the data when the form load.Datagridview have a template checkbox column also where the user will select the class to attend.I want to loop the datagrid and find the selected row ro columns value when the user click the save button How i do this am using vb.net 2008?
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? [code]...
I just made the small following programm (my 1st one) With VB 2008 Express, but the TextBox2.Text will show the countingvalue only when it has finished counting. How can I do to have the textbox showing the value while counting?[code]...
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?
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?
Im new to coding and this is my first post . so please forgive me if i end up sounding stupid i've been trying to get output of a for loop into a textbox or label for example

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.
I 'm currently developing program which I can check the lines of each textbox if it has same length. The code is working properly in few lines like 2000 lines, but when I try to load a textfile which has 50,000 lines, my program is not responding anymore it takes forever. [code]...
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.

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?
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
Private Sub CopySelectedNodes(ByVal nodes As TreeNodeCollection) For Each node As TreeNode In nodes If node.Checked Then 'MessageBox.Show(node.FullPath) Me.CopySelectedNodes(node.Nodes) [Code] ..... This does not work, I want to loop through results so the textbox1 will be like 151,154,3,151, and I want to remove the last.
I have a form with a textbox, a button and a label. If I put a number in the textbox this number shows in the label but after that the label start to countdown from that number to zero.
I am trying to write this loop to find the word start and then insert a word in a column until it sees stop and then go through all the data and do that.
I was using .indexof("myword"), then all of a sudden huge problem and headache... i was using .indexof("produce") and then it kept replacing the word produced cause produce was triggered by the first 7 letters.then i tried to use .contains("produce") and it did the same thing.so basically it doesnt search for the WHOLE word, if a WHOLE WORD begins with the phrase your searching for then it wont work.so how do i search for WHOLE words?
