When run the code Form1 load together with Form2.On Form2 I have Label1.I need that Label.Text flicker or blinking.
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
[Code]...
However, this code will not work, if I use <label for=field_1> as the first string and </label> as the second.
Basically, I'm not sure if I'm thinking along the correct lines when trying to break this down. The program is supposed to display the question "How much is _ x _?" with _ being a randomly generated number between 0-9 which I have in a label. The student inputs the answer and clicks the "Answer" button. If he gets it right, the label below outputs "Very Good!" and automatically puts a new question in the above label. If the student gets it incorrect, the output is "No, Please try again." and the student keeps trying until the question is answered correctly.
My method of thinking on this is that the random.object generator is input first so the question with the numbers are output in the first label. Then, under the Sub answer.button, enter the statements that will either check and refer to the above statements to get a new question or have the student try again until it's answered correctly. One of the other criteria for this is that I have to use a function for the calculation. Would the function statement, because it has to return a value, go before the answer.button code or after?

I'm trying to implement Bandwidth Total calculation into my little desktop monitoring program using 2 *.txt files. Everything else is working great except for the writing/reading part of it. I had put this together originally without the intention of bandwidth monitoring, but I've decided it would be a good thing to have.I want to have 2 monitoring types: Windows Session Bandwidth Total & All-Time Bandwidth Total (since the program was 1st run on the machine). The counter is on a Timer (2nd of 2), and I want it to write and add the label values each second into the file, then when Form3 is opened, to read the text file and show the results.
View 12 RepliesI'm looking to put a few labels on a form but the text that they will display will not be static. Instead they should be dynamic as the values used will be either the value of a specific Environment variable or from a value stored in an array. These values will change depending on which user runs the application. How do I achieve this?

View 1 RepliesI want to randomly input a text line from a .txt to different labels in my program. So far I have this:
Dim FILE_NAME As String = "question.txt"
If System.IO.File.Exists(FILE_NAME) = True Then
Dim objReader As New System.IO.StreamReader(FILE_NAME)
Dim question(5) As String
Dim line As String = ""
[Code] .....
This works perfectly, but as you can see there is no randomization, it just runs through each line. I want one out of every three lines to be chosen. My text file, on each line, has question tab answer tab answer tab answer tab answer tab correct answer. So for the first inputted question i want it to chose one of the first three lines, second question chose a line between line 4,5 and 6. etc.

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

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 need a series of sentences appear on my screen one after the other. I want to have the possibility of:
1) adding new sentences (as many as I want);
2) make them appear randomly;
3) control the time until the next sentence appears (or may be go to the next one by press of a button) (for EACH sentence(for short sentences shorter for long longer));
4) terminate the operation any time.
I imagine it like this: I start the program/application/file -> first sentence appears e.g. "I like ice cream" (randomly out of those that are in the body of the program or in the outside text file) -> it stays on the screen for 2 seconds (controllable) -> next sentence appears e.g. "Lisbon is the capital of Portugal" -> 2 seconds (controllable) -> "Apple is a fruit" and so on in a loop randomly choosing the sentences until I terminate the run of the program.
So my question is: What is the script? And what exactly do I have to do to realize that? My VB level is: installed it yesterday, learnt how to create a button and make "WELCOME TO VISUAL BASIC 2010" message appear on my screen, search all over the internet trying to solve my problem but found only how to generate random numbers.
How to make the picturebox appear randomly? And, when i click on them when it's is appeared, the score will +1? this is Whack-a-Mole, sorry that i don't know what this game's name. Can you tell me how to make the picturebox appear randomly and disappear after a short moment(0.5 sec something). And the game total time i would like to have about 1 minute.
View 17 Repliesso my goal is to get a picturebox to move in random directions and smoothly (like a character moving straight in a game) without using thread.sleep and me.refresh (and also without animation atm). Would anyone be able to guide me on how to accomplish this?The reason I want to do this is because when I need to use like 3 threads to move 3 different things around smoothly my computer slows down too much.here's my code now without all the other subs used to place the random code in it's own thread. There's a lot of other code too so I can't really post the entire thing:
Private Sub random_movements(ByVal e As Integer, ByVal speed As Integer, ByVal ctrl As Control)
Dim location_x As Integer = ctrl.Location.X

Basically I am trying to get my timer to stop when it reaches a randomly generated number.
I have dimmed num2 as integer (num2 is timer)
I have dimmed num3 as integer (num 3 is random number)
I have done num3 = randNum.Next (0, 8)
My timer is working perfectly and counts from 0 -8. My randomly generated number works too, so how do i get the timer to stop when it reaches the random num?
I have tried;
if num2 = num3 then
timer1.enabled = false
But that didn't work
