Use 'Tab Stops' When Concatenating (say) A Label Text?
Aug 14, 2011
Is it possible to use 'Tab Stops' when you're concatenating (say) a Label text? I know it can be done for a PrintLine statement but I'm, trying without success, to put tabs after the colons in this code. ( "...... :" & vbTab ...)
Label1.Text = "Width margins:" & a.ToString & " Pixels." & vbCrLf
Label1.Text += "Height margins:" & b.ToString & " Pixels" & vbCrLf
Label1.Text += "Top margin:" & c.ToString & " Pixels" & vbCrLf
Label1.Text += "Bottom margin:" & d.ToString & " Pixels" & vbCrLf
Poppa.

I have a textbox "myTextbox" and a listbox "myList" which shows a list of strings e.g "AAA", "BBB", "CCCC".When the user clicks on an item from the listbox the text must be appended to the end of whatever is in myTextbox with a space preceeding it. e.g " AAA".The user must never be allowed to delete the added text.The user must be allowed to manually enter text in the textbox but it must always be in front of the added text. They must never be allowed to type over the added text or after the added text.I have been trying to get my head around this for a day now and cannot figure it out.

I am using a label inside my loop to get a count on the number of records processed by the loop. during testing of the program I noticed that if I load a smaller Table( 1000 records) my label stops refreshing after about 110 and my mouse turns to an hour glass. The program finishes and the label returns the correct count when complete If I load a larger table (10,000 records) it works all the way through???

I'm trying to concatenate nonnull multiple columns from a database into the text property of a combobox. Right now, I'm receiving an "IndexOutOfRangeException was unhandled name, address1, address2". The line, "cboFreight.Text = drFreight("name" & ", " & "address1" & ", " & "address2")" is where the error is occurring. Here is my code for this section:

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.

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.

Shapetext = clickedShapes.Item(nextShape).Text.ToString.Substring(0, clickedShapes.Item(nextShape).Text.IndexOf(" "))

This code works if I take out
" " + p.MIDDLE_NAME
Thus the remaining code looks like:
p.FIRST_NAME + " " + p.LAST_NAME
Maybe LINQ-to-Entities just doesn't support concatenating more than two strings at a time?

I'm concatenating data files, but the problem is that I'm seeing some extra bytes where the files are joined. The new file has extra bytes. I had thought this was maybe a problem with encoding.Here are the methods that I've tried to use to concatenate the files. The first example I'm getting extra 0xA0 0x00 bytes.
Dim inputfiles() As String = Directory.GetFiles(sourcedir, pattern)
Dim bufSize As Integer = 1024 * 64
Dim buf As Byte() = New Byte(bufSize) {}

I have this simple-minded query:
select a.str_number+' '+a.str_name+' '+a.str_suffix+' '+a.str_apt AS addr from mytable
This query works as long as none of the concatenated values are not NULL. If any is null, the address does not show.
I tried this:
select IsNULL(a.str_number+' '+a.str_name+' '+a.str_suffix+' '+a.str_apt AS addr,'') from table
What I would like to accomplish is to replace NULL with empty space if the value is null but I still get no values.

I've been trying to reuse my bosses vb.net buildpacket code which he has successful used for Serial programming eg. SerialPort1.Write(buildpacket(useraddress,252,"0006","0") for the function listed below.My challenge.Create equivalent functionality for Socket BeginSend() which requires a byte array.Whether modifying the vb.net below or getting a c# equivalent to work, it has been repeatedly recommended to scrap the string concatenation approach for which I have to use Encoding.BigEndianUnicode.GetBytes() and then getting rid of extra bytes with zero values.
I'm lacking in imaging something different which would work for socket programming directly and allow me to eliminate all the hassles that c# integer conversions into string value that can be encoded trouble free.I would need to call the equivalent of the following that would return a byte array rather than a string with the following arguments
1. Source address (0-255)
2. Destination address (0-255)
3. Function code ("0001" through "0100")
4 Packet Data Unit (pdu - some integer value

I have a label that reads a random line from a text file and that string becomes the text for the label.
Now the problem; the label will only work if it is clicked because the event handler is click.What I need is this to work automatically at startup. In other words, it should change the label's text to the random string of the text file on startup of the application.
Here is my code.[code..]

I am wondering if there is a simple way to make the text to speech occur after the updating of label.text
If I have the following:label.Text = "words words" voice.Speak(label.Text)
I would like the label on the form to display "words words" before it speaks. I'm a beginner with vb, and the only thing I could come up with was to use a timer. Just wondering if there's a simpler/more sophisticated solution.

I have this problem but I already simplify the code as below:Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Label1.Text = "hello"
System.Threading.Thread.Sleep(5000)
'MessageBox.Show("hahahaha")
Label1.Text = "world"
End Sub
What I'm trying to achieve here is, after I click the button, the label1.text should change to hello, and after that to world. But I couldn't achieve that. Instead when I click the button, it just paused for 5 second and displayed world.System.Threading.Thread.Sleep(5000) The code is just a dummy for a loop that I have.

I am new to the forums and just started to learn vb.net. Currently I am making a project that require a lot of text. Since I would need over 20 labels and do not want to hide every single one, is there a way to place text on a specific place on form through coding. Then, I could just make it a sub and easily hide the text and reveal it
