VS 2010 Looping Code X Number Of Times?
Apr 3, 2011
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)

I have set up text boxes for user to pick a number 1-20 and to enter a word as well. Then, press submit button. What's supposed to display in result textbox is the word that many number of times. For example if the number is 5 and the word is hello, then "hellohellohellohellohello" should appear. I don't know how to complete my For...Next function to append the word to the result.

I have a database and I have a form that you can add questions to the database. Once the question has been added, I go to the quiz which uses the database and it goes through all the questions twice. I was wondering why this is happening [Code] Also I was wondering how do I set up the form to be the first form shown on the program?

I have a datagridview with checkboxes in the first column and I want to do a loop on saving the serialnumber(s) when the users decides to check a number of checkboxes Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
[Code]...
the problem with this code is that it only inserts the serial number of the LAST checked checkbox and the number of entries of it depends on the number of checked checkbox for example ... if I checked the rows with the serialnumber 123 and 55652341, first the row with the serial number 123 then second 55652341, only 55652341 appears in the database and it is entered twice(twice because two checkboxes are checked)

I have this program generating a firstname and lastname from a file. When I run this program I enter information in three textboxes. The first two are the salary low and high(salary1.text, salary2.text) and the last one is the number of "copies"(copies.text) that I want.. When I put a number such as 10 in the text box it outputs some of the same names. The firstname file has around 100 records and the lastname file has about 1000 records Why is it generating the same name The problem is even worse if I do something like 1000 copies.. it outputs the same thing 8 times and then does something different another 8 times

I've been running through the online "Code Rules" tasks to work through Visual Basic. However I seem to be having a problem with one. The objective is to set a Button Click method to check if any number between 2-5000 is prime or not and to display it in the TextBox if it is prime. Here is what I have so far but it doesn't seem to work.[code...]

TimeN is system time. TimeF is a fixed date and time. All I need is the number of seconds between fixed and system(now) for timeR (and counting).

This text book i have is not very good at all. the exercise's at the end of each chapter ask u to code projects without first covering the basic of what u will need do to code them. (Programming in Visual Basic 2008 Julia Case Bradley + Aninta C. Millspaugh)
Design and code a project to calculate the amount due and provide a summaray of rentals. All movies rent for $1.00 and all customers receive a %10 discount. The form should contain input for the member number and the number of movies rented. INside a groupbox display the rental amount, the 10 percent discount, and the amount due. inside a second groupbox, display the number of customers served and the total rental income.(afterdiscount).Include buttons for Calculate, clear, print and exit. The clear button clears the information for the current rental but does not clear the sumarry information. A print button allows the user to print the form. Do not allow bad input data to cancel the program; instead display a message to the user.[code]...

I have an SQL database with a single table with several colunmns. I want to count how many times a certain number appears in one of the columns. E.g. I have the following:
A B C
8 4 6
0 9 3
1 4 6
4 7 1
I want to count the number of times 4 is used in column B. I have looked at using the following, but not sure if this is even the right approach:
Dim db as New MainTblDataSet
Dim BCount = Aggregate B In db.MainTbl Into Count(B.B = num)
where num=the number I am counting the instances of (4 in this case).
The hope is that BCount will equal 2, but it returns 0 every time.

I know it sounds strange but let me it explain. It has a purpose, but really all I'm looking for is the item with the most duplicates.I know it's possible and I've had a few ideas already, though none were successful or practical.What I'm doing here that requires this is creating an intuitive search for clients in a database. You type in a single field and click search. Behind scenes each keyword broken down from the single input field is searched through the table of clients, hitting each column and returning matches. the results are large in numbers, but truly it's the client that appears the same number of times as there are keywords.

How can I count the amount of times a character appears in a string?
The assignment is to create a program with 2 text boxes, label, and a button. We then need to type a phrase into the first text box, and a character in the second. Then click the button and then the label will display the output of how many times the character in the second text box appears in the first.
I have all the above setup except for how to display the amount of times the character appears in the first text box, here's a picture:

I'm trying to run a simple select statement using an ADO recordset. But the resulting recordset returns 3 times the number of rows. For example the query should return 20 rows but is repeating 2 more times and returning 60 rows. When I run the query in Oracle it returns 20 rows.
Here's the code.
sSql = "Select * from Sector"
cnnOracle.Open("DRIVER={Microsoft ODBC for Oracle};SERVER=REPDATA.world;UID=auser;PWD=auser;")
