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 am new to vb and need some help with this change program. The idea is that we are given a certain amoun of change and then telling how many dollars, quarters, dimes, nickles and pennies. I thought I would convert the decimal to an integer and then use a while loop for every text box, i.e. dollars, quarters, dimes, etc.., to show how many of each, but the while loop is confusing for me in vb, but to tell you the truth I don't know if I am on the right track,

I have a text file (*.txt) with a name in each line, like this:
Joe
Dane
Lisa
Kelly
Now I want each name added with a number from 1 to 99.
Like this:
Joe0
Joe1
Joe2
[code]....
I have folowing code:
For n As Integer = 0 To (numbernames) - 1
strContents = objReader.ReadLine()
For i As Integer = 0 To 100 - 1
[code]....
With this code all happens ok and a new text file is created with the desired name-list with added numbers.The only problem is that the last name doesn't get a number added from 0 till 99 but for example 0 till 17.
I am new to Visual Basic 2010, but I have been trying to make a line reader with an imported text document into a RichTextBox through an internet source.
I want the RichTextBox's line zero (the first line) to really be line one, but without changing the text in the TextBox to show the change. In other words, I want that change to happen in the background of the program.
I have tried... taking the text from one TextBox and putting it into another, while subtracting an integer value of onean attempt to use a timer to copy the text from one TextBox to another to read the line properly.
I have tried a couple of other things too, but most of them were much more complicated and I could not really explain what each thing did.[code]...
I'm trying to make a notepad type program that is specialized for coding HTML. One of the features

the user is currently typing.[code...]
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

I have a function which iterates through the TextBoxes in my form (and its child controls) and adds each TextBox's name and text to an ArrayList using a structure I called valTxtBox.
Here's a snippet of the
VB.NET
Public Structure valTxtBox
Public nome As String
Public texto As String
End Structure
[Code] .....
Now, the problem is that if I call Clear() for valsTxtBox in the getctrls() function, not all the elements get added to the ArrayList. However, if I don't call Clear() it works just fine. BTW, I'm using VS2008 express which might be relevant.
In one page 10 no. of hyperlink present. If I click one of them then the text which is written in links that will be displayed into textbox dynamically.
For example,
<a href="hello.html">hello</a>
If I click hello. Then hello will be displayed in textbox.
I have written a function that gets the alexa ranking of a given url, now this function works perfectly but I want to loop through a ListView of urls and grab the alexa rank of each item (url) with my function.The code works great if I put a MessageBox in the loop to test that the function is returning a value but when I remove the MessageBox the loop does not work.I need it to loop through adding each result without a MessageBox stop in each loop.
vb
For Each Item In ListView1.Items
Dim result As Integer
result = GetAlexaRank(Item.Text)

View 14 RepliesCan a VB.NET For loop be constructed that mimics this C# code?
TimeSpan oneDay = TimeSpan.FromDays(1.0);
for (DateTime d = startDate; d < endDate; d += oneDay) {

Obviously you could do it without a For loop (i.e., with a While); I'm just curious if there's a certain syntax to construct a VB.NET For loop with a non-integer increment that I'm not aware of.

I've made a program where a picture of a bee buzzes around the form in random movements (using random number generator code) and have put it in a while loop so that whilst the bee is visible on the form (hasn't flown off the sides) it moves randomly:
While (picBee.Top > 0 And picBee.Top < 725) And (picBee.Left > 0 And Timer1.Enabled = True)
Application.DoEvents()
For i = 1 To 3000000
Next
picBee.Top = picBee.Top - 2 + 4 * Rnd()
picBee.Left = picBee.Left - 2 + 4 * Rnd()
End While
So far the bee does stop moving when it meets one of the four edges of the form but I need to code it so when the be reaches the edges and stops a message box appears declaring the game over.
I have a parent panel with child panels that contain images. I am looping through the panels to save the images in the order the panels appear in the parent panel. [code] I can also re-arrange the panels via mouse. The problem is that when they are rearranged, they do not retain their order when saved.. They simply are saved in the order they were added to the parent panel.So my question is, does the for loop use the index set when adding the panel? If so, how can I manipulate the index in runtime while arranging the panels via mouse.
View 4 Repliesi have an SQL statement which i need to code in vb:
create
table r2 (salesno
bigint, prodno1
[Code]....
Note that in this "2nd loop"
- the table name is now r3 from r2 in the first SQL statement
- there are now prodno1, prodno2 and prodno3 instead of just prodno1 and prodno2
- in the WHERE clause, the p.prodNo becomes p.prodNo2
and so on and so forth.. so for the 3rd loop
- there's going to be r4
- there's going to be prodno4
- in the WHERE clause i will use p.prodNo3
what should i do? is there an array or something that i can use here?

What I'm trying to do is write a program to store my sports cards collection. Basically, just a forms based program that stores various data into files. Where I am stuck at the moment is I have a piece of code that opens a form to add card brands. It has a text box, and ADD button and a CANCEL button. What I want to do is be able to type a brand into the textbox and have it store it in a array when the ADD button is clicked, then allow another entry for another brand and have it stored into the array when the ADD button is clicked and so on until the CANCEL button is clicked. Then I would like for the data in the array to be written to a file. Where I'm having the problem is I can enter a brand name into the text box but the loop keeps adding that same brand name into the array.
