View 4 RepliesI am constructing a program, i am new to Visual Basic, but i have past programming experience. I was wondering if anyone knew how to form a loop that could...lets say calculate the answer when two numbers are added together,and it would repeat this thousands of times, etc. And if there is a way, would it be possible to calculate the time taken to complete this loop.

View 1 RepliesA 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?

These are options to one question, so need to in the database under 1 record. so - question1 yes, question 1 no, question1 yes and so on. i want to use a while loop or some other loop to take all these values and insert them or update them in the database for that particular question. i m new to programming. the db table is ID, question, Answer. so it will be 1 question1 yes, 2 question1 yes, 3 question1 no.
View 2 RepliesI have the following code, that in my head should create a new row in a table:
Dim fin As Boolean
Dim db2 As New ChecklistModeldbmlDataContext
For Each a In bServers
If collection("fin" & a.ServerName) = "true, false" Or collection("fin" & a.ServerName) = "true,false" Then
[Code]...
It only ever adds one record in to the table and then errors with Cannot add an entity that already exists.
Now it should enter 4 rows into the table, but I can't work out why the above gives me that error.
I've also tried having the db2.SubmitChanges() outside of the for each and it just inserts the last row.
I choose an item from dgrpoducts which has all the products in inventory and it sends the selected items to another datagridivew called dgiselectedproducts. These are the selected items.

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]...
View 4 RepliesIm 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.

View 3 RepliesI have a form with 4 textbox's
(TextBox1 Called) InsertTextBox
(TextBox2 Called) NormalTexBox
(TexBox3 Called) TimeHalfTextBox
(TextBox4 Called) DoubleTextBox
And my code below I have tried different ways to get the result I want, Let's say I Insert "3.00" into InsertTextBox. The result's I want Are as Follows:
The result I want in NormalTextBox = 3.00
The Result I get is "3.00" this Result is ok
The result I want in TimeHalfTextBox = 4.50
The Result I get is "4.5" this Result is wrong
The result I want in DoubleTextBox = 6.00
The Result I get is "6" this Result is wrong
Private Sub InsertTextBox_TextChanged(sender As System.Object, e As System.EventArgs) Handles InsertTextBox.TextChanged
NormalTextBox.Text = InsertTextBox.Text
TimeHalfTextBox.Text = (CDbl(InsertTextBox.Text * 1.5))
DoubleTextBox.Text = (CDec(InsertTextBox.Text * 2))

View 8 RepliesMakes 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?
See below.

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?
View 8 RepliesIm 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
[Code]...
1) Diff b/w nothing & string in terms of variable declaration.
2)Erase keyword.I have never heard of such keyword in mine whole 1 + yrs of exp.
3) Diff b/w functions & properties? I say,Functions return a value,But propertiesare used to set or get the values. He say properties also return a value.
4)How can we use a class as a datasource?
5)Partial Class? hey frnds above question is for C++ na.Or there is also such class in VB.Net.
6)When the error stack overflow comes?
7) How we can we make indefinite loop , without uusing any variable declaration.
VB.NET While 1 = 1
Dim localRecv As New StreamReader(localClient.GetStream)
Dim aString As String = localRecv.ReadLine
localRecv.Peek()
MsgBox(aString)
End While
Basically "aString" will keep updating if new data arrives to the server. This way does work, and keeps MsgBoxing every time I get new data, but I don't wanna use While, I need something else, because It won't run any other code, just keeps looping that. :/
I have this code.I need to loop through it, until button 2 is pressed.I also want to count how many times its looped and show how many times in a label.

I got my code and the number are finally right the only thing is i can not get it to loop right. It should ask the user if they would like to buy more bars and if they say yes it should continue if it says no then it should exit but everything i am trying is not working.[code]
View 3 RepliesI need an additional loop argument within an If statement that resides in a very large do...loop block. It will speed the application considerably if I can have the do...loop block loop prematurely. I already have the remaining code after the additional loop argument in a large if...elseif block to achieve the result, but making it simply loop instead of going through this would speed the application.
