Currently, I am looking for a solution to makes my data loop at the code behind? It is actually an announcement list that query from database which contains the title and contents.
cmdDa = New SqlDataAdapter("SELECT * FROM announcement ORDER BY announcement_PostDT DESC", conn)
ds = New DataSet()
cmdDa.Fill(ds, "announcement")[code]....
Should I put it into a panel, list view or anything and loop it?
CODE:
That code works to read the entry data and to recognise the correct data, and the incorrect. However, even if entry is correct, the error msgbox will appear (x times of how many records there are in file), despite being navigated to the menu. Anyway that the Else isn't triggered when data is correct. Also for it to appear just one instead of (x times of how many records there are in file.)
Dim Temp() As String, Result As String, HTMLCode As String
HTMLCode = t.Text
Temp = Split(HTMLCode, "/view/")
Temp = Split(Temp(1), "/")
Result = Temp(0)
l.Items.Add(Result)
I don't know how to make a for each loop for this code... What i need is to get the text between "/view/" and "/", which it already does. But it only results in 1 string. I need it to find all the lines that contain "/view/" and end with "/" and extract the text/numbers between them. How do I do that ?
I'm using the Following code in my project, but I cant seem to make it loop as its getting stuck if i specify more than the value of 1 in textbox5.Everything works in a single instance, all is checked to see if it already exists then either generates a new password/serial or commits to the database with the random serial/password
I've tried a few different methods to cycle this code based on the value in textbox5 but i cant seem to figure out whats stopping it working.

I'm having some trouble with a loop that I have to complete. I'll post the instructions and then the code that I have so far at the bottom:2. Start with the lower number.Display every other number starting with the lower number till you get to the higher number. Example if lowerNum = 5 and HighNum = 10 then it will display 5,6,7,8,9,103. If higher number is greater than 25, display every other number from lower number to 25. Example if lowerNum=20 and higherNum=30 it will display 20,21,22,23,24,25

Makes 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?

I created this ASP.NET Web application and I can't get the amoritization table(MonthlyPaymentBox) to loop correctly. I think the problem is somehow in my code I am setting the TotalLoan = 0, but I just can't locate where that is happening. I assume this because instead of of starting the current balance at the users input, it starts at 0.

I'm creating 50 picbox in code. they are named Area1_1 to Area 1_50.

Like this:

' Dim 48 other box...

ive tried multiple times with do...loop and for..next and all that kinda stuff, but i still havent figured it out. what it does is, it only runs through the add me pages and never clicks confirm which is the second part. im kinda new to vb
i know there are no "control arrays" in vb.net. i do come from vb6, and im trying my way now within bv.net, so please be gentel...
if someone could please post a simple code to do the following, it would be great:
i have 3 textboxes called txtBet1, txtBet2 and txtBet3.
i have another 3 texboxes called txtResult1, txtResult2, txtResult3.
so i want to have one loop code, to get the value in txtBet1, calculate somethings, and put it into txtResult1.text.
i know it's basic, but i tried using this sample here as a reference, but its not really understandable for me, because its not really choosing the exact control i want to address...
this is from Microsoft website - a comparison between vb6 and vb.net:
"' Visual Basic 6.0
Private Sub ClearText()
For i = 0 To Text1().UBound

I am using a for next loop to scrape through some html code. I am testing elements for a certain string, and when it hits that, I need to get the string that resides 2 elements earlier.When going through a for...next loop (I know you can loop completely backwards with step -1), is there a way to 'go back' 2 loops?
Ex)for each'lets say we are 5 loops in and our if returns true'can i go back to loop 3, perform an action, then return to loop 5 and continue the real loops?
I am calling a sub from a form load event. The procedure that is being called adds columns to a listview and then loops through an array to populate the listview. I have another procedure called after the loop that does not execute when the loop completes. Please advise as to what I am doing wrong for the code not to execute after the loop in the if/then/else statement or why it is not executing if I remove the if/then/else statement and just placed the called sub after the loop or why the code does not go back to the form load event and then call the next called sub.[code]
View 9 RepliesBasically, what I'm doing is navigating to a website with a backgroundworker.In the WebBrowser1_DocumentCompleted event, I put code to fill in a form and I set the value of a boolean called "formFinished" to true once the form has been finished and submitted. The problem I'm having is that it only posts data to the second website, no matter the order of the websites. I'm wondering how this is possible since I have a boolean in state which only gets set to true once the first form has been submitted. So I have no clue as to why it only submits the second one, but not the first one.

I need help in finding out if there is a more efficient way of writing my code. The code below is a list of radio buttons all of which have different values for example
radiobutton1 has a value of 1
radiobutton25 has a value of 20
the values are stored in a variable called 'count'
the 'count' is incremented by the ammount from the radio button clicked.
Is there a way the radio buttons can be compressed into a for loop and if so how can i still access thier each values.

I'm not even sure what I need to know. None the less lets say I got a timer with an if event to check if said event is triggered then it fires off some code. The problem is if said event is triggered it keeps firing off the code and I only need to do it one time. Whilst letting the timer keep checking if event happened. I hope I worded that right and here is a rough translation in code. [Code] Is there a way to keep checking if an event happened and only fire off the code one time?

this code was not done by me originally and there are some thigns here i dont quite understand i have altered it a bit from my coworkers code to suit my data and it works. but too slow. and when i have 4000+kb excel files it might freeze altogether. ( I have checked tho that when and after this transposer runs it will still be within the excel row limit, i had done calculations before and made a macro to automatically split excel files based on number of columns and rows to make sure this is so ). This code seems to start out fast then goes slower the longer it runs. at least this is what it seems liek to me.
