Send An Update To A Label Control During A Subroutine?
Mar 10, 2010
I want my code to do something that will require a bit of time. I want to be able to send an update to a label regarding the progress of the process during the length of the process, so that the user will know how far the progress has gone. Unfortunately, the label is only updated at the end of the process. I try to simulate it with a simple code below, where the label should be updated from 1 to 10, but it is only updated at 10, rather than 1, then 2, etc until 10. It does not help to show only the end!
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Me.Cursor = Cursors.WaitCursor

I am trying to send data and arrays using System.Object and System.Event. Lets say I have 4 pieces of data: date, y(1),y(2),y(3).
sub main(...)
Dim date,y(1),y(2),y(3) as integer
Dim obj as System.Object
Dim args as System.Eventargs
How do I organize obj with all the integer data above so I can send it to main2.
main2(obj,args)
end sub
Sub main2(obj as System.Object,args as System.Eventargs)
End Sub
And how do I apply this to (ByVal sender as System.Object, ByVal e as System.EventArgs). I am using VB.net 2005.

My requirement is getting output from command window asynchonously in vb.net form, I am doing this with system diagnostic process and using addhandler. My problem is, I have separate class to execute process, after process start when control goes to a addhandler sub routine, it stops there only after it's execution(in addhandler subroutine), and never comes back where I am capturing output. Control should come to the line in below code - addInput = outputExe.ToString() so that I can captureoutput and go back to vb.net code behind.
code is as below
Public Class RunExe
Private Function ExecuteProcess()
procInfo = New ProcessStartInfo
procInfo.FileName = ExeFile

I have been using vb6 for a while, I am following a tutorial by MS to develop a basic application and a simple task cannot be completed for whatever reasons! The tutorial asks to drag the label object from the toolbox and drop in the tab control container. Then, go to the label size property and adjust the size to some different dimansion. Basic stuff, right? It won't let me do it! After I enter the new dimensions (which by the way are not large or very small), the label size (both width and height) resets back to its original dimensions! I have the vb.net sp1 installed.

I am trying to send keys to a control on my form. But I am getting a NullReferenceException and I don't know why. The code is about as basic as it gets: [Code] The error reported is object reference not set to an instance of an object but Send is a shared method so doesn't need an instance. Strangely if I ignore the error it works fine and F4 is passed to the control. I know there was an issue with sendkeys and UAC but I thought this had been solved (I am using 4.0 framework).

I'm trying to make a label control transparent over a Panel control.However by setting the background colour of the label to Transparent, it actually sees right through to the form itself, not the panel as intended.
As an example we use a panel with a background as white, we make the label transparent, however it gets the form�s colour as blue.However, we are using a custom panel control and need the label to be transparent over the panel and not see the forms background.

I am trying to learn Background worker and have written up a very simple app to understand this process. My form has a
textbox and a label. When the user clicks on the button, it updates the label with the value that they have entered into the textbox(I know this can be done elsewhere in the code besides the dowork event, I am just
testing and learning). Please help..I am not sure what I am missing. The label does not update.

I've been having this problem with my program hanging up sometimes. I tracked the problem down to the following statement:
me.lblPrompt.Text = strInfoToDisplay
So I checked strInfoToDisplay and sure enough it had in there what I thought it would. So then I checked lblPrompt. I'm using the command window and just using? me.lblPrompt.Text to get the system to tell the the value. Well, guess what it does? It hangs up. I haven't been able to get the command window to tell me one time what's going on. However, I know it has to work sometimes becuase the program (from the user standpoint) doesn't always freeze up the way it does when I can't read the prompt.

So, I'm working on a simple game in Visual Basic, and I have 2 labels. One named "pointsLbl" and one named "pointsleftLbl":
pointsLbl.Text = "Points: " & points
pointsleftLbl.Text = "Points left: " & pointsleft I also have two integers, one named "points" and one named "pointsleft". The problem I'm having is that when the point boost button is pressed, the labels don't update and also don't show the new points and new points left. Private Sub boostBtn_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles boostBtn.Click

i have a MDI application with parent and childforms.
i have a global timer in a module that makes a com search and writes the result to a parentform status strip label.
the problem is that the label do not change.
i have tried the following:
1) on timer.elapsed
parentForm.statusstriplabel.text =...
2) to create a delegate and invoke a parent form function
3) to create and raise an event
although all 3 seened to run the label didn't changed.
the timer was created in a different module than the parentform class for many reasons.
one of them is because i want to access the timer.start , timer.stop from all the childforms
when i tried a local timer to paretform worked perfect but i couidnt start and stop it from the childs

I'm trying to update a label to indicate how many items in a CheckedListBox are checked. Here is the code I'm using:
Private Sub CheckedListBox1_ItemCheck(ByVal sender As System.Object, ByVal e As System.Windows.Forms.ItemCheckEventArgs) Handles CheckedListBox1.ItemCheck
Me.Label1.Text = "(" & Me.CheckedListBox1.CheckedItems.Count.ToString & ") of (" & Me.CheckedListBox1.Items.Count.ToString & ") Items Checked"
End Sub
It should say "(x) of (y) Items Checked" each time an item is checked or unchecked, but it's not updating the label properly, the count is always off by 1.
