Is there is a way to remove the white box around the series label in a chart. I am using the built in chart from the toolbox in Visual Studio 2010. This is the last part I need to finish the appearance of the chart to make it look the way I want.

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 am stuck on how to assign values on a label or text box.The issue is the following:I have two tables, one called A and the second one called B.Table A has tree fields: id, name, lastname...Table B has five fields: id, level1, level2, level3, level4..The idea is to save A.id into level1, level2, level3 and level4. A.id can be the same or not. I know how to assign and save the values on the DDBB using DDL, but when I want to show the values using labels, I get the first value always, this is becuase the select command is configures in that way. If I use ddl instead label, it works, but I do not want to show the value using ddl. I want to use label to show the values, and ddl to modify or add new data into the DDBB.[code] As you can see the level1 uses label, and level2 uses ddl, it was the only way to get the value for level2, otherwise if I use label on level2 it display level1 value instead.I would like to know if there is any way to assign different value using anything but ddl.

I've come up with the following and it's partly working.
Public serial1, serial2, serial3, serial4, serial5 As SerialPort
Public serialports() As Object = New Object() {serial1, serial2, serial3, serial4, serial5}
dComPort = "COM4"[code]....
The above code works fine! But im having trouble trying to now retreive whats stored in the array.In the above example, an entry will be stored in serialports(4), all other array elements will be blank.If I do this it works.
MsgBox(serialports(4).PortName) ' this retuns the value COM4
But I'd like to loop though all array elements and print out ALL the PortNames, The below code doesnt work, I get an error Object variable or With block variable not set.
For i = 0 To serialports.Length - 1
MsgBox(serialports(i).portname)

I would like to create a filepath and assign it to a string (so that it can have yet more added to it later on in my program) the code takes (well i want it to but it doesn't) the name of a drive selected previously and then adds this to a string to create a string variable that refers to a file. and then (as usual) i want to use thes files and display them in a combobox but i want to only select files that have a pre selected 2characters at the front. I have got this code so far:
' search for filer drive NETAPP-1
For i = 0 To frmDatabase.drvDB.Items.Count - 1
If InStr(frmDatabase.drvDB.SelectedText(), "\Netapp-1malika", CompareMethod.Text) Then

I'm trying to create a web site that users can log into and self serve their user information ie name, address etc. I've set up a SQL server DB with a couple of table holding the data and accessing those using Linq. I'm selecting specific data from my datacontext then trying to assign it to a label, ideally I want to assign the value to a class attribute so I can use the users details on multiple pages.
I've simplified the code (removing WHERE statement etc for the purposes of this question):

I feel quite silly asking this, but I couldn't find a definite answer anywhere. in vb.net, how are the array elements defined (if they are defined) for, for example:
Dim myarray(5) as int
does, at this point in time, myarray(3) for example have a defined value? If so, what is it?

I am new to VB 2008 express (I am a 'C' coder but have played with VB6 before). I am writing a simple program that will use the serial port. What I would like to do is, upon some trigger event, open a form, and depending on the amount of serial ports available, populate this form with an array of checkboxes with each check box corresponding to an available serial port. The user could then choose a port which would then determine the PortName.

i am very new to VB and have been trying to make a hangman game. I was wandering if there is a way to add multiple label boxes to a form based on the size of an array. For example a user inputs the word h-e-l-l-o in a input box that word is then split and put into an array(arrword) then i want the main form to appear with 5 label boxes each one containing a letter that from the array(arrword)

Any hunk of code that loops trough the windows form controls array, and based on top/left to bottom/right, resets the TabIndex property? I've mashed a huge form together and expect my user community to want to move things around, and I don't want to have to fool around with this over and over again.

I have a text file which I open and then read in 1 line at a time and split up. I then takes each component part from the split string and assign it into a variable as I go.
I then want to specific varaibles and put them into an array and build the array.
Can I read in each element and assign it directly into an array or is this was best.

I seem to be getting an error when I try and directly add items into an array

I have an array of type Double() (1 x n) that I am trying to quickly plot on a graph I've already set up. The only thing I want/need to do is take my array and store it as data points (y-axis values) in the series I already have. What's the best way to do this? Also, will the data points that are plotted change as my array changes, and if not, how would I replot those new points and get rid of the old points?

I am having a problem with objects and arrays of objects. Basically obj_stored holds how many objects I have stored in my text file, in this case t shirts. line(y) is an array that holds each line that has been read from the text file. I then use this to assign values to my array objects properties. For example I know the first line is the color of the first t shirt, second size, third price etc. Then I know the next line will be the color of a new t shirt. There are 6 t shirts in the file.
Dim t_shirt(5) As Clothing.t_shirt
Dim t_shirt_purchased As New Clothing.t_shirt
For x = 0 To obj_stored
t_shirt(x) = Clothing
t_shirt(x).color = line(y)
y = y + 1
t_shirt(x).size = line(y)
y = y + 1
t_shirt(x).price = line(y)
y = y + 1
Next
MsgBox (t_shirt(4).size)
My problem is it seems to be resetting these values after it has finished. Im creating the object each time and assigning values to it's properties but when it's finished it all resets and says 'Object reference not set to an instance of an object'. I'm new to OOP and was wondering what sort of approach i would take to doing this, if the one i am taking is wrong.
So I am aiming to:
Read everything in from the text file.
Create new instances of the objects depending on how many t shirts are stored, (5 t shirts = 5 objects)
Assign the values to my objects properties.
