Check For Same Numbers?
Oct 8, 2009
I have a textbox, with the following items anim,welcome,30anim,items,20 I am using rhe following code to read each line in the textbox Dim MySplit() As StringDim MyLine() As StringMyLine = Split(tags.Text, vbCrLf)' Split the Contents of the tags TextBox at the Line SeparatorsFor Each mLine As String In MyLineMySplit = mLine.Split(","c)anim_time = MySplit(2)Next The code works fine forward, it sets the variable anim_time to its correct value. What I want to do is to make it check for similar numbers one item backwards. For example: anim,welcome,20anim,items,20 Here the two anim_time as equal. I want to warn the user that this is happening.

I have a question about working with arrays
I don't have any code written out I just want to know the best way to do this sort of senario to put into a flowchart, the program i'm working on isn't homework, its just practice and the book I have is less than helpful with what i'm working on.
I want to check to see if at least 3 numbers in the array are the same but no less so that it meets a certain requirement how would I check this?

I have a working piece of code that checks that 4 out of 5 random numbers are in sequence. The numbers correspond to 5 dice rolls. I'm trying to learn VB and I think the code can be improved since it's so cumbersome. The sub checks to see if any of the numbers are duplicated and reassigns one of the duplicates to an arbitrary "11" which is outside of the 1-6 range of a single dice roll. Then the values are inserted in an array and sorted and the sequence check takes place. score of 30 is assigned if 4 of 5 of the (sorted) numbers are in order. If not in order, a score of 0 is set.
Code follows:
Private Sub OtherScores4()
'Check if any of the rolls are duplicated and reset one of the die to arbitrary "11".
If Dice1 = Dice2 Then
Dice1 = 11
End If
If Dice1 = Dice3 Then
Dice1 = 11

I need some kind of code to check if the first line in a richtextbox contains numbers or not.
Something like this:
If Richtextbot1.Lines(0) contains Numbers Then
Goto startbot
Else
[Code].....
If the first line contains 4 or more numbers, it will use it. After each loop it will delete line 1. So it repeats for the next line. When my code reaches the 3rd line, and it doesnt find 4 or more numbers it needs to delete the line.

Im trying to write a program that will do:
1.The average of the four numbers. This answer will be placed into a text box reserved for that value. This text box cannot be changed by the user.
2.The maximum and minimum values. These will be denoted by changing the color of the largest number green and the smallest number red.
3.The range of the numbers. The range is defined as the difference between the largest and smallest numbers. The range will be placed into its own text box, labeled as such. This text box cannot be changed by the user."
Im using visual studio 2008 and it has to be written in VB

So how would I use .next (random numbers) to randomly select something from a list of numbers but it can't repeat the number?I could do:
dim num as integer
dim r as new random
num = r.next(1,5)
if num = 1 then
elseif num = 2 then
etc.
That wouldn't work because it would repeat.If I donwload someone's game can I disect it in VS? :0 I tried going to open project, then I went to the folder and clicked open. It brought me inside of the folder so I tried to open the game but there is no form1 there. It says the games name then .exe in the explorer-like thing in the top right?Also, how would I have a value or something in a label and access it from a button.
Example:This is in a label.
Dim number as Integer
number = 0
Then in the button do
Label.number = 0
How would I do something like that? I want to use that a lot as I did in a different language.

I am making a program, where the user enters 6 numbers in 6 different text boxes, and it displays the larger of those 6 numbers. But I also want to make it where if the user enters a string value (like S for instance) in the text boxes, it gives an message and says "please enter the numbers again" and the user gets to enter the 6 numbers again. But when I do try to do that, it gives an error message saying conversion from "w/e the user entered" to Double is not valid. If the user just enters the numbers, it works fine. However, I am trying to make it if the user does enter non numeric value, it gives a message window and the user can reenter the numbers again.
Here is my code Example
CODE:
This is where I am trying to use IsNumeric to show a message if a user does not enter a string so the user can renter the numbers again, but when the user does enter a string value (say in textbox 1) it gives me an error message saying conversion from "S" to 'double' is not valid.
CODE:
Then right here this is where I have my series of ifs statements, this part works fine, it displays the largest numbers of the 6 textboxes every time. Error free.
CODE:
And do this with variable number 2, 3, 4, 5.
I know there are easier ways to do these with arrays and stuff. But I am not there yet. I am still learning about ifs and stuff.

I have just about completed a .NET project to write a program to randomly select numbers for a Bingo caller. Over the last month or so Ive learned a lot about .NET but heres something that I consider to be odd and maybe one of you guys can offer an opinion.
One of the features of calling Bingo in a small local club is that callers often use little sayings to accompany certain numbers, I expect youve all heard of (say) All the sixes, clickety click for 66 or 5 and 9 the Brighton line for 59 etc. My little program gives an option to incorporate these with a prompt for the caller that can be edited outside of the program. One of these conventional sayings is used when a number is reversed 12 followed by 21 or 45 followed by 54 for example, when the caller might call (say) 1 and 2, one dozen, number 12 And the other way round 2 and 1, twenty one.
So, I programmed in a bit of code to detect this and to over-ride whatever might otherwise have been the quote with And the other way round and set about testing it. Ive been through literally dozens of full 90 calls watching for the occurrence of a reversed number, spent a few hours doing it, and not once has it occurred which is to say the least, unusual.
So, Im wondering about the Rand Function, could it be that it isnt possible for a reversed number to be selected? Just so you know, I randomly pre-select the order of all 90 numbers, I fill each of the 90 elements of an array with a random number first checking that the number selected hasnt already been stored, if it has, I just get the next random number (and check that too of course), but I cant see how that could prevent reversed numbers being selected, especially in light of the fact that frequently it's not the 'next' number that's used.

I'm using VB08. I've populated a listbox with numbers and I want to add all those numbers together and display the result in a Label. I've heard about using parse but I don't understand exactly how it works.
This is the code that I have that i think should work.
Dim lblTotal As Decimal
Dim sum As Double
For Each decAdded As Decimal In Me.lstRunningTotal.Items
sum += Double.Parse(decAdded)
Next
lblTotal = FormatCurrency(sum)
When I run it, nothing happens. My "For Each" statement I'm not sure if it's doing what I think it's doing. I can't believe I spent 6 hours banging my head against the wall but I finally got it figured out.
This is my revised code:
Dim sum As Decimal
For Each decAdded As Decimal In Me.lstRunningTotal.Items
sum += Decimal.Parse(decAdded)
Next
lbl_Total.Text = sum
Just some suttle changes made the difference

I just D/L VB express 8, and I'm trying to learn how to use it. what I'm trying to do is write some code that:takes a number into a text box (textbox1.text)do some simple calculations with that number when I press a button (button1)display the results in a second text box 9textbox2.textThe first problem I am having:The numbers are in the "milli" range, meaning to the power of negative three, so 10^-3 = 0.01 I do not want to enter 10^-3 or any other exponent into the textbox, I am simply entering in 10 because all my units will be in milli. I've tried using exponent and scientific notation but it doesn't calculate correctly. I've done a "work around" to get it to do what I want, but there has to be a simpler way to achieve the above results without. for example, the user enters 10 into the textbox, the button multiplies 10^-3 *30, as a crude example, and stroes that value (say, B=10^-3*30) and B is DIM B as Double.
Problem number two:Error checking. I need to validate that only numbers can be entered into the textbox, or else the program will display an error message (messagebox). I can achieve this to some degree with sample code from here and other places, but, some of the code does not take into account that some numbers have decimal places (I have foud code that does, and it does work), but if a users enters, say the letter "E", it crashes the program. If the user enters "10.3Z", it crashes the program. I cannot seem to code for the last case, a mixture of numbers and letters to get an error message box.
