Number Beside The String And The Number Will Increment Which Time The Button Is Clicked?
Jan 31, 2009
I created a listbox using VB.NET. When the user select an item (it is a string format) in the listbox and click on a button, there will be a number beside the string and the number will increment which time the button is clicked. Anyone know how to do it...?Below is the coding I'd done, but I don't know how to do the increment part. Anyone know what coding I need to add?
Dim no As Integer = 0
listBox.Items.Add(listBox.SelectedItem & no)

when i clicked the final button to display my results "as string" it still showeed the number?? here is the code i wrote, is relativley simple, but the theory doesnt make scence to me Basicly its a box with 3 lables, (first name, surname and age), 3 text boxes (for the user to input this info) and a button at the bottom called "display in message box" so when i click the button, it displays the users input in the form as a message box. [code] what i dont get is if i said to VB that vaiable "Complete" was STRING then howcome it still displays the AGE which is an Integer (a number) not a string??

In VB if you prompt the user for a number between 1-20, then a word, how do you get a text box to show the word the same number of time as the number selected using loops?... Ex: please select a number: 4 / select a word: cat....the text box should display ::: catcatcatcat ........
I am doing this for a class and my brain has locked up. Prob. just over thinking it though. Thanks in advance for any help!

I heard that you have to add some code to a random number generator
results(1) = Int((5 - 1 + 1) * Rnd() + 1)
so that if it is used again and again it keeps generating new numbers as apposed to what this piece of code does by itself which is creates the same number every time.what is the code?

How do I programmatically increment a given version's number to the next version of the highest one?
For example if I have a file Program.exe with the following version numbers :
Program.exe 1.0.0.0
Program.exe 1.0.0.4
Program.exe 1.1.0.76
Program.exe 1.0.0.66
The next version number in this case would be 1.1.0.77
What's the easiest way to implement that?

I have a HFScrollBar on my design page, and a TextBox Right above it. I want the text in the textbox to start at zero, and what I want to do is make it where if i move the scrollbar to the right, it increments that number, and if I move the scrollbar to the left, it decrements that number. I have tried to code this, but realized i was about 1,000,000 miles away from where I am supposed to be lol. So, I wont bother posting what I've tried. A simple straight-to-the point tutorual on this subject would suffice, though.

This feels like a completely basic question, but, for the life of me, I can't seem to work out an elegant solution.
Basically, I am doing a LINQ query creating a new object from the query. In the new object, I want to generate a auto-incremented number to allow me to keep a selection order for later use (named Iter in my example).
Here is my current solution that does what I need:
Dim query2 = From x As DictionaryEntry In MasterCalendarInstance _
Order By x.Key _
Select New With {.CalendarId = x.Key, .Iter = 0}
[Code]....
Is there a way to do this within the context of the LINQ query (so that I don't have to loop the collection after the query)?

I've been using some recommended code from successfully for a couple of years now to auto-increment the build number in my project.
[URL]
But I just updated my workstation from XP Pro x86 to Vista Ultimate x64 and now it isn't working any more. Everything else works, but not this. It increments the build number when I build the application, but then VS gives the following error:Error 4 Unable to apply this change while debugging. File 'D:My ProjectAssemblyInfo.vb' was reloaded. You must revert the change or stop the debugging session.So essentially I can't do anything in my application, or at least I can't run in debug mode because of the error.

It was very practical to keep build number in VB6, as it auto-incremented that number every time that i "compiled" the program.
There is any equivalent feature in VB.Net? I am using VS 2005.

I have an SQL statement which i need to code in vb:
CODE:
Notice the fields prodno1 and prodno2 in the table structure.. this is part of a number of sql statements i need to run and put inside a loop. my problem is i want to automatically use this same code such that on the next loop, this sql statement is going to be:
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

The problem is, once it has found a duplicate item, it stops counting.What I'm trying to say is, it finds ASP 2 Advanced as a duplicate, with its "click time", it finds Dreamweaver Advanced as a duplicate, but doesn't find its "click time"I need to find the items, then add together all their respected click times, for example: ASP 2 Advanced has 5, then 2 So the total must be 7 Dreamweaver Advanced has 1 and 1 so the total must be 2?

Just getting started in VB.NET. I would like to add X-number of text boxes at run time. And then be able to address them by their index or some sequential numerical value (like an array)
This is what I have so far:
CODE:
When I turn this into a loop to create multiple toolboxes, how do I assign a name to the controls, or will all of them be named "MyTextBox" ? I'll increment their position so thats no problem.
