I'm writing a program, intended to get a number of points from a label control, and decrement the number in the label control as the number in the Numeric UpDown is increased, and increment the number in the label control as the number in the Numeric UpDown is decreased.
Here is an example of the type of code I'm trying to use to do this with:
Sub UDStrValueChanged(sender As Object, e As EventArgs)
Dim points As Integer
Dim tempcheck as Integer
Dim oldvalue as Integer
If oldvalue < UDStr.Value Then
For i = 0 To maxrows - 1 For h = 1 To maxrows Me.Controls.Item("TextBox" & h).Text = ds.Tables("TestCriteria").Rows(i).Item(0) Me.Controls.Item("NumericUpDown" & h).Value = ds.Tables("TestCriteria").Rows(i).Item(1)
This is my way the dynamically generate a mathematical equation everytime the button is click. However, I want the combobox or the numericupdown turn disabled when the next question show out. For example, if the question N is generated, the combobox and numericupdown of question generated before N must be disable means that the user only can input to the current question but cant change the answer of the previous question?
Private Sub btnnext_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnnext.Click If counter < 10 Then Dim pnl As New Panel pnl.Height = 40 pnl.BorderStyle = BorderStyle.FixedSingle [Code] .....
I am making one program, it goes like: I put some data in textbox and when I press the button it goes to listview this part is no problem, but I don't know how to sum data what is entered in listview column nr 4 when I press some button and display the result in one other textbox or label.
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.
I need to identify when a user clicks one of the updown arrows in a datetimepicker. Can that be done?ValueChanged event occurs whether the user clicks an arrow or if the value was changed programatically. I need to determine which method was used.
Is there a numeric text box, not an up-down box, a SIMPLE numeric box into which the user can place a number, 5 boxes actually, then on command have the five boxes added and the sum displayed?
I have written a public sub to update a label on a different form by passing in an integer. If I pass in the -1 value it will update the label, but if I pass in any other value, it will run the code (verified by stepping line by line) but the label won't update, even when adding the doevents.
Public Sub mstidlbl(ByVal cnt As Integer) SyncLock Form_PG_Collect_Master_ID_Label If cnt = -1 Then Form_PG_Collect_Master_ID_Label.Label1.Text = "ID: Paused..." Else
I have a label on my form and I want it to be a certain size, never changing, regardless of content. In the label properties, I've tried setting auto-size to false, setting the minimum and maximum size to the size I want, and setting lock to true. When I update the label's content via my code, it still changes the size of the label.
I use the following code to create a Label in the status strip when a child window is open.Public Sub StatusStripPanelAdd(ByVal lCount As Integer, ByVal sImage As System.Drawing.Image, ByRef sText As String, ByVal sender As Object, ByVal e As System.EventArgs)
I'm working in VB, VS2008, winforms.I've got some labels to create, and I'm using the BorderStyle = FixedSingle.Is there any way to change the color of this border?It is always defaulting to black.
I'm trying to change the existing 10 labels color on my form at runtime they are named this way (label1,label2,label3...label10) however i haven't bin able to successfully do it so far. Here is the code:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim LabelArray(10) As Label For x As Integer = 0 To 9 Dim strLabelName As String = "Label" + x.ToString [Code] .....
I am trying to make a label that changes every second for an event. What I currently have makes the thread sleep all the way through from "Rock" to "Shoot" and skips the "Paper" and "Scissors". Does anyone have any ideas as to what I should do to properly display the label so that they are all displayed in equal time increments?[code]...
I am making a program (obviously), and when the user presses UP, DOWN, LEFT, or RIGHT I would like to move the label's location correspondingly. Here is my code so far, but it does not work:
I have a label on my code and i have 3 lines on it , what i want to do is to have my first line on white color and bold , next line normal white and third line on yellow normal ..
Public Sub SetLabelColours(ByVal Colour As String, ByVal TFont As String, ByVal TColour As String, ByVal TSize As String)[code]...
Is there a way to do it in 2010 .Net? It errors on Forms. also it doesn't like FontSize, I don't see a setting for font size in the drop down, can we set it no more in 2010? I am using RTB's as well.

Im trying to write a program that has a thread and the text of the label should be updated every 100 milliseconds. I have the following code but it doesn't work.
Private Sub ThreadTask() Dim i As Integer i = 0
[code]....
I get this error message if I run the program:Cross-thread operation not valid: Control 'TimeLabel' accessed from a thread other than the thread it was created on.
I need to Change text of label One by one with One timer For Example! "S" 'step1 "Sh" 'step2 "Sha" 'step3 "Shar" 'step4"Shari" 'step5"Shariq" 'step6"ShariqD" 'step7"ShariqDO" 'step8"ShariqDON" 'step9
I need to create a simple label and when the user clicks the label, the label changes color...sounds easy BUT...if the user moves the mouse cursor away from the label and then clicks the label a second time, then label returns to its original color. I am trying to create a loop to loop through two array indices, but it just doesn't seem to work.
i have been trying to get a module to change the text of a label but it does seem to want to.
i havent coded for a few years and in the days of old i remember it being easy, i.e form1.label1.text = "what ever". only that give the error reference to non-shared member.
so i dim formstat as form1 and try again with formstat.label.text = "what ever" only this time it give the error nullreferenceexception was unhandled
