I'm using VB 2010 Express and have a label named "lblTitle" in my form.The next code doesn't work and I know it , but how can I do something like this?
Dim bla As String
bla = "lblTitle"
bla.Text = "Hello world"
[code].....
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.
My vb.net application needs to use a session variable. I don't really know how to use it in ASP.net. I've been trying to use what my books have, but I can't get this label to work. I need the user input to be validated against the database and if their code is in the database, the textbox should disappear and a label will appear saying Welcome. The way I wrote it, I get an error saying the server tag is not well formed and in the codebehind it says that the ID of my label is not declared. Can anyone spot any problems with the code I wrote?

Is there a way to do something like: (where csinglechar is the number being read from the text file)
Dim Number_File As String = "numbers.txt"
Dim read_numbers As New System.IO.StreamReader(Number_File)
Dim intsinglechar As Integer
[Code]....
When a number is read in the text file, the label: labelNUMBER_FROM_TEXT_FILE increments by one.
I would like a label to always show the current value of a boolean. This will change a lot of times and would like the label to ALWAYS reflect this.
Is there some kind of way to have the label set to the boolean byref (so its always the same). Currently I'm assigning the label.text = boolean onLoad, so if the boolean changes after that its not reflected.
I'm working on my final for VB.NET, and maybe it's just late...but here's how it goes. I need to make a variable named intMoney and it will be used to keep track of how much money you have and the value will be displayed in a label. Since this 'game' will have a lot of things going on, it needs to be available in a lot of places, not just one click event.
But I need to set intMoney to a starting value of 200 and then assign intMoney to a label called lblMoney. I can't assign intMoney to lblMoney in global. I get build errors. Where should I put the lblMoney.Text = intMoney?
I have a label in my Form which on loading, displays the contents of a text file. The contents of the text file may change and if so, the number of lines also will. I would like the Form to automatically resize itself based on the number of lines in the file. If there are more lines that the size of the label can take, I would like it to either resize or show scroll bars.
View 2 RepliesIn visual basic , when you create a label in form view (via click and drag) is it possible to make the label have both a string and a variable included in it?
*
turns=1
label1.text = ("Turn:"(turns))

for example , so that label 1 will display
I have an assignment that requires me to use a variable from an InputBox and place it on a label. That variable needs to be formatted using the P0 formatstring but results in the folowing error: Error2Option Strict On disallows implicit conversions from 'String' to 'System.IFormatProvider'.
Here's my

Say that i have the following code that parse about 20k records from the DB.
Code #1
vb.net While reader.Read()
list.Add(If(Integer.TryParse(reader(0).ToString, 0), Integer.Parse(reader(0).ToString), 0))
End While
And then another code which does the very same thing but it seems to be a little cleaner.
Code #2
vb.net While reader.Read()
Dim storeowner As Integer = 0
Integer.TryParse(reader(0).ToString, storeowner)
list.Add(storeowner)
End While
This is what i am confused about; does the compiler creates a new variable automatically when i use the if statement without strictly declared variable? What approach is better in sense of performance?
I am trying to count how many items are in an ArrayList and then save that into a Label variable that is updated each time an item's barcode is scanned.Information about the code below:rejectedList is the ArrayList that contains rejected parts.RejectedPartsNumberLabel is the label I am trying to update with the count from the ArrayList
Public Shared Function isFault(ByRef code As String) As Boolean
rejectedList.Add(code)
RejectedPartsNumberLabel.Text = rejectedList.Count
Return (code.Length = 7 And IsNumeric(Mid(code, 1, 1))) Or (code.Length = 4 And Mid(code, 1, 2) = "NC")
End Function
I'm trying to use the timer (not a Timer object) in a Do... Until loop. I want the loop to put a single variable into a label. When I do this it works and puts the value into the label (lblOxygenReading):
If btnGetOxygen.Text = "Get Oxygen Reading" Then
Select Case True
Case rdoColorWhite.Checked
strCurrentColor = "White"
Case rdoColorRed.Checked

It goes through the Do loop and the For.. next loop but doesn't change the label. Visual Studio doesn't show any errors when I'm writing the code, but when I run it, it hangs somewhere.
Say I have something like this
Dim Level1 as Integer = 83

I have a problem to solve and not quite sure if the way I think is correct.
I have a main form class MainForm the class has got: a variable call Value and a label called LabelValue
Now I would like to automatically update LabelValue every time the Value changes his value
I want to alter the .visible property of a label based on if a variable is positive or negative (Hiding it for negative values)
But I want to do this for lots of labels so If Statements are too bulky.
I tried this:
Label1.visible = CBool(IntVariable1)
But it turns out CBool returns True for ANY value and False for Zero.I'd assumed it would be True for positive values and False for negatives.How can I do it without if statements?I considered Modulo or SquareRoots to somehow convert a negative number into zero, but didn't want to complicate things with imaginary numbers.
i tried to change back color of a label by command button by using a variable value
Private Sub Button3_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
Dim colorof As String
colorof = "Color.Red"[code]....
but its giving error and is not working,
Label1.BackColor = Color.Red is working but I wanted to do this with variable value
Here is my code:
number = 1
If chkFN.Enabled = True Then
If ProgressBar1.Value < 100 Then

If a string variable contains the name of an integer variable how do I then use the contents of the integer variable.i.e.I have a string variable called 'Rowname' which will contain the name of an integer variable.The integer variables will have been previously defined with values such as RowA = 0, RowB = 5, RowC = 10..I now want to add together the contents of the variable defined in 'RowName' with a the contents of an integer variable ColumnNumber.
View 7 RepliesI'm trying to write a sub that when sent a form (if its needed) will create a label on that form. This is because all of the forms will have the same title label. My problem is that, basically, I have no idea how to do this. I also can't get labels to create when the code is written into the form itself; I tried:

In several of my apps I have Build Date shown in the Help -> About screen, just so that people can see how recent the version of the app they are using is. I just manually set the text of this label to the current date whenever I compile a new version of the app, but on more than one occasion I have forgotten... so I'm wondering if there is any way I can automate this?So just to clarify - I do not want today's date (as in the date that the program is being run on), I want to get the date that the program was compiled (either at runtime or compile time, just as long as I dont have to manually enter it)
View 7 RepliesI just want to to change a label name from the backgroundworker, the code is plain simple:
label1.text = WebBrowser1.DocumentTitle and the error returned would be "Specified cast is not valid".
Now running the code from a button would do the job, but from the bgworker not, and I can't seem to get around it.
I think I have created a label array, the labels are not there when the form loads they are created as a result of another event. I want to create a subroutine that executes when one of these labels is clicked but VB doesn't seem to like lblEventArray(1)_Click so

When the form first loads there are two global variables (assigned values in the form load sub as a default) that set the number of days back in time and how many days ahead events will be displayed (in an array of labels). If the user wants to view more events (or less events) the number of labels displayed (and the text they contain) will change. I have one sub (code below)that creates an array of labels.

I'm trying to extract the text between: <label for=field_1> and </label> I have captured the HTML into a string using the webbrowser control, and am using the following function to try and get the text within the tag:Public Function midReturn(ByVal first As String, ByVal last As String, ByVal total As String) As String

However, this code will not work, if I use <label for=field_1> as the first string and </label> as the second.
I made a lot of letters, and I set all of thiers background color to Transpert. I STILL don't see any transperancy, because when I put "one letter on the other one", i can see thier background.

View 11 Repliesi want to create a program that pressing a button will increment an integer variable and a textbox will show the result. Te code i wrote is below:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

i = i+1
textbox1.text = i

now, the same code works for the vb6 form but on vb 2010 the textbox just show 1 and does not increment any further.
I am busy doing a little project for myself, but seem to have hit a stumble block, and i have been on the net for days, but cant find something that works, so hopefully someone here might be able to assist me. I have a windows form, a xml document and a label on the form, i want the <description> node of the following xml document to populate that label, if needs be, i can change the label to another control.
