Make RadioButton Only Usable A Limited Number Of Times?
May 15, 2009
I need to know to limit the number of times a radio button can be used. Maybe the number of times the radio button has been used can be stored in an XML file, and when the user wants to reset the counter all they would have to do it delete this file. I really don't know, that's why I'm asking you. But,the program will append a string every time a button is clicked with a radio button selected, I just need to know how to, for instance only allow RadioButton2 to be used in this manner say... 15 times.

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
Public Class Form1
Dim sex As String
Function randomfirstname()
Dim infile As IO.StreamReader

A few years ago I have been busy creating this application but it didn't succeed, now Im coming back to it and similar problems occur. Basically I use SetPixel on a given window to draw a line, work fine, but the line goes away as the window redraws itself.The problem: I have been putting timers and threads on it to make sure the line is being drawn. Is there any way to make a loop to make a certain thing happen about 10-30 times without taking in too much memory/CPU?

Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim timeN As DateTime
Dim timeF As Date = #7/11/2009 12:43:20 PM#
Dim timeR As TimeSpan
timeN = DateAndTime.Now
timeR = ?????
End Sub
End Class
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).

I have a VB.Net Winform showing checkboxes inside the ListView which works fine. I want to know how to make the checkbox work like the RadioButton. ie. I should allow the user to click only one checkbox on the listview. If there are 2 checkboxes in 2 rows and then when the 2nd checkbox is checked, the first checkbox "Checked" should be cleared. When the 2nd checkbox is clicked the 1st checkbox "check" to be cleared.

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.

Basicly my instructor said that we have to make a program that will count how many times we enter a number into an inputbox, he also said we had to use a while loop. [code]

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;")

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 a list of 100 assets that are pulled from AS400 and shown on a gridview alongside a dropdown box with 6 possible status and a textbox.
If the user selects a status other than "Found" (whether it's "Not Found", "Scrapped", "Sold", "Transferred","Other"), the user cannot leave the textbox empty. They must insert a comment into the textbox. Once the user is done he clicks "Save" and if, let's say, the status is "Sold" and the textbox is empty for all assets then a Message Box pops up saying "Please fill the textbox".
The problem is, the message box pops up 100 times (or once for every asset that has the error).
1) What can I do so that the message box only appears once even when 100 assets have the error?
2) Also, when the message box appears and I click "OK" the information the user had filled up to that point gets erased.

I am trying to write a random number function that can just be called from my main module to generate different random numbers. I have tried this several different ways and I am having odd results. Approximately 19 times out of 20 the numbers come back exactly the same, but approximately 1 in 20 they come back as two different numbers. Im using Visual Basic Studio 2008. Here is the code I have so far, or rather, the current version of my many tests I have been running to try and figure it out. Sometimes it takes many runs of the program before the two seperate numbers apear.I've been researching it and have come up with nothing so far.I know I could put them in the module section as two different randoms and it works, but I get extra points if i use a couple classes in my program.This is the main module.
Module Module1
Sub Main()
Dim randomNumOne As New RandNum[code]...........
