[02/03] Can't Read Or Update Label Text
Feb 18, 2009
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.

In my vb.net winform application, on click of start button the label1.text should be "process started" then some filesaving method will run after finish that method the label1.text should change to "file saved".
Private Sub btnStart_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnStart.Click
lblStatus.ForeColor = Color.Red
lblStatus.Text = "Saving to File"
[code]....
the initial status of label "saving to file" is not comingup. after the Trigger method finished, the status of the label is changing to "File saved"

Is it possible to read a label's text property of another app? I know how to get the handle of the main window, and how to get the handle for a child. But the problem is that there's like 20 other labels on the window and when I use winID to get it's class, it's just "Edit", and it's the same for all the labels. And the title is the value of the labels text property. [URL]

I have several group boxes on a winform. within each there are several labels.I am accessing the group boxes with no issues but I can't seem to find a way to update the labels within by looping. They have the same name except the last character which is a number 1 - 9. ex. lbl1, lbl2 ... lbl9.I need to update the text of each label in code with text I get from a database ex. lbl1.text = one, lbl2.text = two etc... I want to loop through the labels to assign the text. Getting text from database is no issue what I am not doing properly is getting the labels.
do while QstNum < 10
Dim ln As New Label
ln.Name = "SC_Cat" & QstNum

I have a Main Module that loads a form. I want to update text on a Label, my code is:
Public mFormSplash As Form = New FormSplash
Sub Main
With mFormSplash[code]....
The code loads the form OK but does not update the Label's text (LabelStatus)I am getting an error Error:
'LabelStatus' is not a member of 'System.Windows.Forms.Form'.
This worked ok on a previous project and I can't work out what is different.

I have a form that I am loading text (strings) from a database into a label.text (so the text from the database shows up into the label) I have done this code in a class that keeps all my database stuff seperate.
Public Function getQuestions() As List(Of String)
Dim question As New List(Of String)
objConnection.Open()
objReader = objcommand.ExecuteReader
[CODE]...
Within the form that the label is in I have done this code
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Label1.Text(db.getQuestions().ToArray)
End Sub
I am basically making a quiz, so that when the form loads, question 1 is on there is 4 possible answers. You then press next button and it goes to the next question.

I am using a label to display a song for an mp3 player. I wanted to scroll the text inside the label for anything that is longer than the label width. I figured out the width of the label and if the width of the text inside the label is longer. But I have no idea how to turn this into subtracting parts/pixels of the text currently displayed and how to append the subtracted parts to the end of the new text.
Sub f1timer2tick()
Dim g As Graphics = f1l2.CreateGraphics
Dim s As SizeF
If f1l2.Text.Length > 19 Then

basically i need to change the text of a label where the name of the label comes from the value of a variable.So, for example,
Dim x as String = "lblTarget"
Dim y as String = "Target Text"
In this case the text of "lblTarget" would need to be come "Target Text". Basically, the label that is named the value of variable x would need to take on the text of variable y.

Is there any way to detect if the text in a label is longer than the label itself (assuming autosize is set to false)? I want to trim the text in a label so the last line is a finished sentence (everything after that sentence is removed). I hope you understand what I mean.
I want to go from this:"Hello. This is a test string. Most test stri..."
to"Hello. This is a test string."
Is there any easy way to do this?

I am creating a Pizza Order program as part of my coursework college. why something isn't working.
Quote:
lblTotal.Text = Val(Form2.lblPizzaTotal.Text) + Val(Form3.lblDrinksTotal.Text)
The code above is what I am using to add the Value of Label 1 (Pizza Total) and Label 2 (Drinks Total), however it seems that in the final total it doesn't appear to add the value of Label 2.

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.

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 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'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.
