Any Way To Change Labels Inside For Loop?
May 19, 2009Is it possible to change many labels inside a for loop? Let's say I have labels 1 to 4. Can I do something like:
for i = 1 to 4
label%i.text = some text
next

View 4 RepliesI 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.}

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.
Basically I have 10 .png images.They contain a walk cycle I need to make some kind of loop inside a timer to make them change.
View 2 RepliesI am making an invoicing application. I have a label (lblCost) inside of a UserControl (InvoiceEntry) inside of a FlowLayoutPanel (pnlEntries). InvoiceEntry represents a line item on the invoice, and pnlEntries is the "body" of the invoice. pnlEntries can hold several InvoiceEntry controls.
I am attempting to sum all of the lblCost values from each InvoiceEntry control to make a subtotal, and I want that subtotal to change automatically if costs are changed (e.g., a change in quantities being ordered). Is there a way to handle when the lblCost.Text property of any of the InvoiceEntry controls contained within pnlEntries changes?

In the program that i'm working now a button create's a new tab witch contains 5 labels and 2 buttons.Of these 5 labels 3 have fixed text but 2 of them have variable text witch i need to save and reload at startup each time(until tab is deleted)
i figured out how to save tab's and make them reload at startup and suceded on saving the 2 labels text in a specialized stringcollection but on startup it only load's the last memorized string in the selected tab , the other tabs label's are blank.
how to load the other labes text?
I have a load of information on my label in a groupbox on the form there is too much information to be seen in one go so i want to use a vertical scrollbar to move the label up and down inside the groupbox so it can be read.
The issue i'm having is:
1: The label covers the bottom edge of the groupbox (looks a little naff) i need it to fall inside the groupbox if possible.
2: Any movement on the vertical scrollbar seems to send the label in one direction only - so how do i work it so that up moves it up and down moves it down?
Should i use a multiline textbox rather than a label and move the carat?
I've made a user control and have added some internal labels inside it. In the User control class I'm trying to handle the mouse events so that: When the mouse enters the User-Control the background of the User-Control turns white - using MouseEnter event. When the mouse leaves the User-Control the background of the User-Control turns grey - using MouseLeave event. However as soon as I move the mouse over the internal labels it triggers the MouseLeave event. I don't want it to do that, because the mouse hasn't left the bounds of the User-Control! So, how do I get it to not trigger the MouseLeave event when the mouse is still internal to the User-Control?
View 9 RepliesI'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?

View 3 RepliesI 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.
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:

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]
View 3 RepliesI 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

I am writing a program and i need to declare matrices but there will be a different number to declare everytime the program is run so I was wondering if anyone knew how to declare them inside a for loop

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.
