Save The Information From Each Activation Of The Code Inside The Loop?
Jun 11, 2011
How do I save the information from each activation of the code inside the loop. I decided to try this a different way. I also need to know how to create colums in a label?
For countInteger As Integer = 0 To 3
seatsSoldInteger = ticketDetail(countInteger).seatsSoldInteger
costDecimal = ticketDetail(countInteger).costDecimal
totalTicketSalesDecimal = ticketDetail(countInteger).totalCostDecimal

I'm foolin round with stream reader/writer and I'm running into this problem: If I have my if/then statement inside my loop I get a million msgboxes(which I understand why), however if I put it outside my loop, and the if/then returns a false then the whole program freezes up. I can't move my mouse around, I can't click on any objects, ect. Here is what I'm using:

I have a question about loops that I don't know if it can be done. The program will send data through a parameter to an Oracle DB. What I am trying to do is during a loop I want to be able to send information from one text box, the next time it loops to send information from another text box ect. ect. I was hoping I go do it this way instead of writing out a bunch of parameters in both the program and in Oracle. Can this be done or do I have to write a whole lot of parameters out?

Using VB.NET .NetFramwork 3.5. This fails and strikes me as odd. Is this correct behavior:
Public Sub TestForEach()
For index As Integer = 1 To 10
Dim z As Integer
Assert.AreEqual(0, z)
z = index
Next
End Sub
I would expect z to always equal 0 as I thought the dim-ing of an integer would set the value to 0. If you run this. It fails at the second loop. For some reason z retains it's value of 1. I know I can manually initialize z to = 0, but I wanted to know if this is a bug or expected behavior.

I would like to be able to stop a loop while executing using the ESC key.I've found a lot about using the above key from within a Form (for example, to unload it), but very little for the use of the key within a Procedure (Sub, Function) and particularly with respect of preventing a loop from carrying on execution.

For i As Integer = 1 To 10
Dim j As Integer = 10
Next
now my question is, Is memory allocated to j every time its executed inside for loop? or only value of 10 is assigned on subsequent iterations?

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim s As New Staff
[Code]....
Basically I am trying to update each record with 2 random numbers each time the button was clicked,my problem now is, the system will update the record but the data was wrong. Example, by right all data should be different (randomly string) but for some row it was updated with same data but in randomly, something row1 row2 row3 has exactly same data for column 1 and 2 then row 3 has distinct data, second time, row1 row2 same data row3 ro4 with different data. It is in random sequence. When I add a MsgBox to do testing in the For loop the data was updated correctly with all different data.

I am trying to input specific information on a form. I have created an sql statement from a table that will out put 18 rows of data. I have opened a recordset and instituted a do until loop. I need for the program to look at each row and if the Standard Score = the value of a field I have on the form it takes the value of the other three columns in updates it on the form. I have created the code and it works for upto 3 (Do Until loops)records, but when I try to add a 4th in the SQL statement and put in another do loop my computer runs it but it acts as if it freezes up.

I have some variables that are distinct by numbers, like in1, in2...If I have for loop, how would I access those variables, using the counter, and attaching it to the variable?I believe in JAVA, you could just use in+ct... where ct is the counter to access the variable.also how could you make a new variable in the for loop?Initially I had variables declare outside of the for loop. The problem was how to access those variables using the for loop.
var_nm1 = in1.Text
var_nm2 = in2.Text
var_nm3 = in3.Text
Dim nmList(2) As Integer

I would like to show that the computer is busy and not frozen during a long file transmitted over Serial Port.I have the following loop.The intention was to show one "*" for every line sent.
While (fs.EndOfStream = False)
lineRead = (fs.ReadLine)
TextBox1.Text = "* "
SerialPort1.Write(lineRead)
End While
I can see the data sent on the Scope but the chain of "******...." show up after the transmission ends.The WHILE LOOP is actually working but the TextBox1.Text = "*" is not writing to screen.I would like to see the train of ******** same time as the transmission is active.The * is to show that the computer is busy and not frozen.Writing a copy of the actual serial data transmitted to screen is also another option that I can use.

Im using Vb.net visual studio 2008. i have got a process(system.diagnostics.process) to be run in background and it updates the Ui thread progressbar and a label and i have worked it using backgroundworker.runworkerAsync. Now the problem is i have to work the same process for a number of time with different inputs.
The code block is :
Private Sub fnStartEvent(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnStart.click
Dim inputFolder = Directory.GetFiles(textboxSourceFolder.text)
Dim currentNumberOfFile As Integer=1
[code]....
The problem in here is the fnStartEvent method once gets started, it calls BackgroundWorker1.runWorkerAsync process and that runs in a seperate thread and does not wait for the thread to complete and it moves to the next line of code i.e loops to the next item and it returns to same BackgroundWorker1.runWorkerAsync line and throws exception that it is already running.
Tried
1.
Private Sub fnStartEvent(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnStart.click
Dim inputFolder = Directory.GetFiles(textboxSourceFolder.text)
Dim currentNumberOfFile As Integer=1
[code]....
But this does not updates the Ui thread used to denote progress.
2.Put the whole process inside the DoWork thread and loop for each file in there itself, but that to returns the cross thread error in progress bar updation.what is the standard procedure in executing a loop for the backgroundworker to wait for finishing as well as update the UI without blocking it.
