Update Labels Text Within A "for Loop" Sequentially?
Apr 20, 2009
I posted in the wrong forum the first time around, and I'm pretty sure that's why it never even appeared. Oh well. THIS is the right forum now, I hope, so here's my problem:
I'm basically simulating bowling. I've created a form that has a "scoreboard" on it, and I'm updating the cells of the scoreboard to display the bowl result. Without doing 21 if statements, I figured I could call a method, send it which roll number it is, and then use a for loop to update each label's text values.[code]...

I am using a variation of Stanav's example from the previous post seen in Sub dd_Inhoud_Labels. The first 3 Subs (Add_Titel_Label, Add_Byskrif_Label & Add_Lewering_Label) is allso shown below so you can see what I am leading up to. Sub Add_Inhoud_Labels is not only responsible for creating labels but allso placing them acording to the location and size of the previos label and allso ather properties as Font and so on depending on the marker at the start of the text string saved in the data base.The problem I can not get solved is that only the last of the Inhoud Labels seem to be created, it seem to be in the correct location as last label as seen in the pic below

Is this possible? I have tried a few different methods with no luck. I am more of a JAVA person, but am taking some classes for VB, and have been playing around. This is what I have tried:
[Code]...
I think I'm going about this the wrong way, but would like to know if anyone has achieved this. All I'm doing is printing a simple character map to 255 labels, each label containing a char. Not an assignment, just having fun.

I'm trying to loop through Labels that are named Label1 through Label16 and output integers from Array into the Text property of the labels. I think everything works except I can't figure out how to assign MyLabel the value of the current Label # in the loop. [code]

I am writing an app to be a single button failover of a set of mirrored SQL servers. The app has to handle several other functions (enable/disable and start/stop of services, writing to local registry, copying files from server A to server B, initiating stored procedures, etc.)I have a collection of labels that indicate the status of 4 services on 2 servers, I wrote a function to check the services when passed the machine name, and the service name. Originally I just called the function 8 times (4 services, 2 machines) and populated the labels 'manually'. I have all of this within a timer so that the service status is refreshed every couple seconds. Id like to clean up the code to a single for/next loop that operates on 2 arrays (an array of service names, and an array of labels) such as:
'**Fetch_Status is the function that gets service status, it accepts 2 strings, machine name
'**and service name and returns status "running", "Stopped", as my_status
Dim Services() As String = {"Service1", "Service2", "Service3", etc.}
[code]....
The only reason I want the control array is to be able to use the .Text and .BackColor properties of the labels in the loop. If I make an array of strings with the label names it doesnt seem to pick that up.

I created a program that has serval labels on a form and a listview object. It has a button that when clicked reads a textfile and loads up values in the listview object. I then can click and drag text from the listview box to any label on the form and then the program removes the value from the listview box. Now, my question is how can I instruct VB to save these values in the text property of the labels so that the next time the program is loaded the labels will contain the values loaded during the last run time session?

I'm trying to have a for each loop in which 5 labels should be created.Each time the loop restarts the 5 labels should appear in a tabpage.The problem is, it only makes a label once, then it keeps on mving the label to a different tab instead of creating a new one for each tab.
It loops 5 times, thus filling 5 labels.Then the next 5 labels should get filled in a new tab.But it just moves the original labels. How do I force it to create a new label each time?

I have a form that uses 28 checkboxes (checkBox1 ~ checkBox28), 28 labels (label1 ~ label28), and 28 textboxes (textBox1 ~ textBox28). These items need to be visible/invisible depending on the mode of the program (there are 5 modes). I could specify each item individually with visibility, but that requires a whole lotta code! Is there a way I can loop through 28 labels?

Basically what i am doing is clicking on a picture in a Picture box and posting a label to the spot i click on. in some instances i will need to put as many as 60 labels on an individual picture. Below is a snippet of code that works perfectly fine to place 1 point. What i would like to do is setup an array of labels. Something along the lines of

then be able to loop through the code below until i get all my labels placed. The only issue is that when i try doing that i get an error that Label is a type and cannot be used as an expression. Is there another way to do this that i am not seeing?

I want to be able to reveal and then populate a certain number of labels. The inefficient way would be to SELECT CASE on the number of labels required and then populate these in turn. I am looking for something like this:
For i = 1 to RequiredNumOfLabels
Label & i.visible = true
Label & i.text = DataTable.Rows(i).Item(2)[code]......
is the problem as after the line is executed, lbl still equals nothing.The reasoning behind it is that I was trying to create an invoice generator in vb.net and I was hoping that this would be a simple way to do it - count the amount of items in the order, populate the labels with the names of the items, reveal that many labels.

I have attached the form in initial state. What you don't see in the initial state is 10 hidden labels. I want the loop(which I am calling as a function??) to compute the numbers and display in the labels. Example, if I input 1 for the first term, 3 for the second term and 4 for the total terms, the first 4 labels should become visible and have in them one solution each:
1 - 1
2 - 3
3 - 4
4 - 7
Am I way off with what I want to do? Cannot use arrays, must be a loop.This is the compute button:
Private Sub BtnComp_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles BtnComp.Click
Try

how to permanently save to text files then re-open all of the information again using SFD and OFD. Now my teacher has come back at me and said that i need to be able to save the information from multiple text boxes and have the text in certain labels to also be saved into the one text file (the labels need to be done because it is a database and these labels are like the fields and the right text box needs to match the right label)

I have an application that downloads about 19,000 records from a SQL table and I need to step through all the records doing a calculation on each then create a new Excel workbook with the data.
[Code]
m_rows does accurately report that the number of records in the datatable is the same as in the SQL table. I can add records to the XLS file with a for/next loop but they are all the first record of the datatable. So now that I have the data, how do I go through each record sequentially?

I want to rearrange a list of items in different orders for few times; ie: the 2nd in the list becomes the 1st & the previous 3rd becomes the 2nd, ... then the Last one becomes the penultimate one.In the next round, the 3rd of the original list becomes the 1st & the 4th of the original becomes the 2nd and so on. (That is, each item moves one rank above & the Top one goes to the Bottom)Given below is an example.Here, I took only 6 items & rearranged for 5 times only. (I should be able to use several Items and to rearrange for many times).The Original List:
(1) Alpha, (2) Beta, (3) Gamma, (4) Delta, (5) Epsilon, (6) Zeta
2nd List:
(1) Beta, (2) Gamma, (3) Delta, (4) Epsilon, (5) Zeta, (6) Alpha

I am getting data from an SQL Server Database to display into text boxes.
However I also tried getting individual data or current data to display in the Gridview but not working. I am sure I am not doing it right.
I can get the data to display in the Grid view but not individually or scroll through as I hit the next button.[code....

Learning about threads at the moment, barely managing to wrap my head around it, anyway I was wondering how you would go about making threads run sequentially from threadpool if you added them with
threadpool.queueuserworkitem()
In my code currently I know it is not running sequentially as I set it up to call a function and print a number each call. I gather this could be achieved with using synch lock but not quite sure how.

Is there any way using existing .NET framework classes/methods that you can sequentially read a byte array? I dont mean just using a for loop to loop through from the beginning to the end, I mean having the kind of methods that you have when working with an IO.Stream subclass, such as ReadByte. I thought I would just be able to construct a new IO.Stream class and pass it in a byte array but it seems that Stream is just for inheriting and cannot actually be used itself. I could implement my own class that just has an internal position counter and a byte array and then each time you call ReadByte on that it advances the position and returns the byte at that index... but it seems odd to have to implement such a basic thing myself.

in the program im trying to make i have a button that when clicked starts a fairly lengthly loop, takes a couple minutes to complete. while this is happening im trying to send the an update of the loops progress to a listbox i have setup. Unfortunately these updates dont make it to the list box until the loop is finished, ive tried this with a few different types (progress bar/ rich text box etc). i cant seem to get any form changes through while the loop is in progress.
Is there some option or event thing i need to specify to be able to make changes to the form while in a loop?

I have a program which I'm designing to help organize and move some of my music around. I can create a play list and then add music to it, when I do this it copies the mp3 files to a specified folder and also updates a listbox with the content of that folder.
The code works, however when I run it the program locks up until everything has been copied, the listbox goes from blank at the start to suddenly showing the whole list.[code]...
