I put this mathematical formula in VB 2008 Express Form and I have the result show in TextBox and every thing is good so far and my question is if I have a table of numbers for example if the answer in the TextBox is 0.00098 and my table show :
0.0001 to 0.00100 = 7
0.00101 to 0.002 = 8
0.00201 to 0.003 = 9
Etc
I need the number 7 to be displayed in label 1 so how can I do that?
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 trying to display in a label the appropriate number of dashes based on the number of letters in a word that the first player entered.
Basically, when you click play, the first person enters a word, then the second player guesses what it is. That person has 2x #ofletters of incorrect tries. I just need to figure out how to get the dashes to display based on # of letters and not a preset one of 5 dashes. The original program accepts only 5-letter word so that line of code is Me.lblWord.Text = "-----". I have modified it so the user can enter any # of chars. I tried making the above line with a lot of dashes so it but the leftover dashes will stay there and the game won't end. Here is what i have right now for my play button:
Private Sub btnPlay_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnPlay.Click

I have some variable that when divided I get this symbol: -1.#IND when you look at the variable in debug. This only happens when I put the equation in the Dim statement.
[Code]...
I don't have a problem. Why when I put the equation up in the declaration area it sets it to -1.#IND (I assume this is infinite or NAN or some such). I'm curious as this is the only time I've had difficulty with this.
Here is my code:
number = 1
If chkFN.Enabled = True Then
If ProgressBar1.Value < 100 Then
number += 1
lblFN2.Text = number

I am just wondering how I can make a listbox count the number of selected items and display it in a text label. My listbox selection mode is on MultiExtended.
Also, can someone provide the definitions for:
SelectedItem
SelectedIndex

I want to display an equation prior to solving it. Obviously in MS word etc I can use equation editor to write an equation, but I'm writing my own program.
Is there an easy way to display an equation. Obviously I could use text to write eg as text "a=b^2-3(c-d)/5" and everyone here would have little problem interpretting what I want but I want this to be accessible to 12 year old children.
Alternatively I could try and manipulate lots of text boxes one on top of the other to try and explain what I'm doing
The third alternative I thought of was to write in equation editor export the graphic and then import a graphic.
I'm sure I must be trying to reinvent the wheel - which I believe is the one thing OE programming is supposed to avoid.
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 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
Dim nRandom1 As Integer
Dim randomgenerator As New Random[code]....
I want to make the first number greater than the second because the numbers should be subtracted .

I have to create a list of 25 randomly generated 0s and 1s in a list box?Next I have to count the number of 0s and put in one label box and number of 1s in another label box.
txtTotalMem.Text = lstInfo.Items.Count
but it counts the overall amount. I need just one type. I tried using the lstRandom.SelectedItem method but you never select the item as it is just random generated numbers. The (relevant) code so far is
'Load the listbox with 25 random numbers between 0 and 1
Dim intCounter As Integer
For intCounter = 0 To 24
lstRandom.Items.Add(RandomGenerator.Next(0, 2))
Next intCounter
'Calculate the number of 0's and 1's stored in the listbox and place in appropriate labels

I am trying to run a nested loop; it should call a result from a MDB database. Which it does, when I run the single loop it goes thru all of the entries. But when I try to get a number to display twice it stops on the second entry. Having it display the number twice is just a test to make sure it does work, I am going to modify it after I can prove the loop works. The count on the Message Box is correct, but the number displayed is wrong?I want it to display each number twice and then move on to the next number. [code]
View 2 RepliesI have a label that is supposed to display a word for 5 seconds and then move down the list in a text file and display the next word.I'm oddly able to make it work in random mode, but not going down the list in order.. random would be ok if used words didn't come up again.

I'm trying to create a microwave simulator in vb.net. I have button from 0 to 9. I wanted to know how can I add number to label without replacing the s number that is already in there before. What I mean by that is if I press button1 then button 2 ; label should show 12 . so on if I press button1 , 2 & 3 it should show 1:23 but no more than 3 digits in label.

View 1 RepliesLet's say I have a label which looks like this:
2 12 22 25 27 31
then i generate numbers.How can I try to find a number using a integer.I tried:
VB
If label1.text.contains(integer)msgbox("found match!")End If
But it matches each number. For example if it is 3 in the integer if say that there is a match because it finds the "3" in 31 etcHow can I make it find the whole "3"?
I really can't figure out, how to display 0,00 or 56,00 or 3,50 in a label. You'll see this 0 or 56 or 3,5.

View 1 RepliesI have a button and a text box. The text box should start out with number 41. Each time I click the button the text box number should decrease by 1 until it hits 20 then when the button is clicked nothing happens. I have tried multiple pieces of code from For counter 41 To 20 Step -1 to If counter <> 0 Then textbox -= 1, but it only works for one click. Not sure how to keep it decrease on every button click until i get to 0.
View 6 RepliesI have a timer that basically counts a number up in sequence in a label. On the On Text Change sub for the label I have functions run when the label is at a specific number. Everything works fine, the only problem I have is I have information pulled from an ODBC link to a pervasive database every second, which slows down the program. I have several flash components that run so slowly because of the data update. Now I have tried both using a dataset and coding the query but it is still ver slow and processor intensive, I think its because the Pervasive ODBC link is somewhat slow. Is there a way to have my data pull timer run in the background so that it doesnt effect the performance of the rest of the program?

This question is a follow up to an earlier question I had that was quickly resolved. The previous question can be found here: Selecting TOP 4 records from multiple SQL Server tables. Using vb.net..I selected the top 4 rows from multiple SQL tables ordered by date. How would I then go about placing that data into labels. There should be 16 items in total (4 columns, 4 rows). However if I try to use sqldatareader I only get items 0-3 and anything more is outside of the array. Should I not be using an IF statement in this case? In addition to the newly formed select statement based on the previously linked question, here is what I have: [code]
