[URl] The code in question is specifically at line 143. Whenever I try to access a label in the array like so Dicelbls(0).Text I get a null reference error. Obviously I am not declaring the array right?
View 3 RepliesI 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

I'm having a hard time displaying random numbers from a button the labels on the same form. This is my first time dealing with VB in general, and I'm having trouble locating this for a project.
I have another assignment as well for my class (which uses an earlier version of VB than me), and I'm pretty much doing everything on my own in a different format for the newer version. how to use an array for images as well?
I have a problem: When try to change the text of a label array (label(1).text = "Lol") then I get a error:
"Cross-thread operation not valid: Control 'lblCSCH1' accessed from a thread other than the thread it was created on."

Private Sub Cliente_Receive(ByRef message As String) Handles Cliente.Receive

I am attempting to create a program that opens a file and reads the contents to then display them in a set of four text boxes (e.g. id, firstName, lastName, avg.Salary). it stores the data in an array.
i have done all that i can do, however, i wish to display in a label something similar to this "5/10 (5th record of a total of 10)" meaning the 5th record in the array out of a total of 10 records. i have already done the code to display the total amount of items in the array, that part was simple, but i can't get my head around trying to code something that will display the record that i am currently viewing in the text boxes.
i have a "view previous record" and a "view next record" button that will go through to the next or previous record, in doing so will change the "5/10" records to the next appropriate number, e.g. "5/10" goes to "4/10" if the previous button is pressed (in doing so, obviously the records that are shown in the text boxes will change to the next or previous record)[code]...
I'm new to VB and new to programming in general. I'm working on some code for school which I'm taking online, and the book doesn't do a very good job of explaining how to do this. The array in the txt file contains this info.

I have a list box, which will contain the item numbers and then a price label which will contain the item price. Here is the code I have, but when it reads from the file, it puts all information from each line. I understand why it does that, I just need to know how to set it up to read it as an array.

Retrieving a single word from an array and into a label/textbox?
View 5 RepliesI got a string array & I need to show the contents of it to a single label. It acts like a clock. The thing is I tried with everything I could but I failed. This is the code I've been trying. Its in vb.net. And theres a thread running to slow down the loop so I can display the contents in a label for 2 seconds.
Dim j As Integer
For j = 0 To readText.Length
label.text=readText(j)

I have a list of names in a database and what i want is to get all of these names and display them in a label or a text box to the user on the website. I have tried to do this using a for loop but it is always overwriting the label each time. I have a list of 10 different names in the database and what it is doing is putting the first name in the label and then overwriting this with the second name and so on until it reaches the last name. I think i need to store each of the names from the database into an array or an arrayList and then make the label display all of the contents from the array or arrayList. The for loop i have used for this is:
Dim g As SQLadmin = New SQLadmin()
g.DB("SELECT nameOfPerson FROM Persons")
For i As Integer = 0 To g.array.GetLength(0) - 1
[code]....
i can select the names from the database and store them in an array then make the label display each of the names.
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)

Using Access 2003 and VB code, I have created a form with a number of labels. The labels will display an employee's names. I have named the labels name1, name2, name3...etc. Using an ADO data set and DCount I have determined the number of names in an Access table (the number of names can vary). What I want to do is for each record in succession to pick the first name and surname from the data set , combine them into a full name (this part has been successful), and then set the full name into the label caption in succession. Example: full name 1 into name1, full name 2 into name2, full name 3 into name3... until all names appear as labels on the form.
I created a counter to and a variable to increment the label number but when I address the caption property of the variable containing the new label (e.g. name1, name2..etc.) it throws an errer at runtime. Here is the code:

'Displays Correct or Wrong in Labels
If ui1Textbox.Text.ToUpper = "FOOD" Then[code]....
I finally finished all my labels and textbox codes for this button.But now I have to code it so that I will be able to click the button and it will calculate all the wrong and correct answers in the labels and then finally place the percentage score in the uiScorePercentagelabel. What I dont understand is how to calculate all the different labels as one and then show the percentage right in the appropriate label.
I have been using vb6 for a while, I am following a tutorial by MS to develop a basic application and a simple task cannot be completed for whatever reasons! The tutorial asks to drag the label object from the toolbox and drop in the tab control container. Then, go to the label size property and adjust the size to some different dimansion. Basic stuff, right? It won't let me do it! After I enter the new dimensions (which by the way are not large or very small), the label size (both width and height) resets back to its original dimensions! I have the vb.net sp1 installed.

View 1 RepliesI made a program that generates random numbers and places the numbers in two separate labels.How can I make the number in the first label greater than the number in the second label.Here is my code for generating random numbers:
Dim nRandom As Integer

I want to make the first number greater than the second because the numbers should be subtracted .

View 3 Repliesbasically 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 am still a beginner programmer so keep in mind that what I'm trying to do is beyond my knowledge but I have no one to teach me Visual Basic except from what little I can learn off of the internet. Currently, I am using Visual Basic 2008 Express Edition so my problem may be appear different if I show you any of my code.
I've created a program that contains a label and the words in the label form a question. Below that is a textbox with some text that has to be memorize for a play. Just think of the question as the previous speakers part. So far I've set it so that the words in the textbox are randomly removed and are replaced with a blank. I face with the program is that the user can't enter the answer because the blank is in the way.
Instead of putting a blank where the missing word is I would like to have some textboxes put there that way the user can enter the missing word and so that I can later insert some code that will let the user check to see if the answer they entered is correct.now the missing word is still replaced by the blank so I need to get rid of that and insert the textbox wherever the words are missing.
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?
What is the difference between a regular label and a static label?
