how to I use loops to display this?

What I'm trying to do is: Set numbers (0-51, a deck of cards) in an array like card(0) = 23 (Which would represent, say, the Jack of Clubs). Then card(1) = 35. Now I have two arrays.
The first array is what I have mentioned above.
The second array is holding a Boolean value. So what I do is make a loop going through the card() array from 0-51. In this loop it generates a random number between 0 and 51. Then I check the second array (iCardUsed()) to see if it holds the random number.
So iRndNum = 13 (Say 13 was the random number)
loops through the second array checking if the there is a value of 13. If there isn't then I want it to set card(whatever it was on, say 12) = 13. then make iCardUsed(13) = true saying card 13 was true. I'm not too sure what to do if it was true, not false.
Alright, now that I explained what I was trying to accomplish, I'll post some code and the project.
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim iCard(0 To 51) As Integer
Dim iCardUsed(0 To 51) As Boolean
Dim iValue As Integer
[Code] .....
Now, this works, but there are some duplicates in the array. I'm not sure why there would be duplicates. It worked fine when I manually entered data so the logic of it is right. [URL].
How do I make a loop from 1 to 100 and make it everytime it loops display incrementing numbers to the screen?

Now I'm having some trouble displaying the output using the do while loop, and I'm pretty sure it's a loop problem on my code. However, I cannot seemed to find out what's wrong.

View 7 RepliesAny right direction for best practices of memory allocation. (i.e., disposing of forms, setting variables to nothing). I am writing a program and for now, I just monitor it in Task Manager. I notice that the size change isn't very balanced. The amount of memory used when a new form loads isn't as much as when that same form is closed. (either by button or by the 'x'). I want to get a handle on this before I get too deep in the program.
View 3 Repliesi need to programm an application which reads the pixels from screen and then manage to read the word. The problem is the white text always changes colour slightly so when i use getpixel the value(as long) is always changing although it is always regonisably white.convert them into black and white or is there any range of values which describe the white color?
Note: This is not for violation of any rules especially because its a game programmed with java.
I'm struggling to solve this problem and am throwing it out to y'all...
For example, if I had a value of 6.5, (representing 6.5 feet), I'd want to separate that value into two values:
6 - 12" sections
1 - 6" section.
This initial value could be any number from 3-16, in .5 increments. (3, 3.5, 4, 4.5, 5, 5.5, etc.)
I have a external hardware that has a miniplug output that i connected to my pc microphone input. That output has two posible states, white noise or no sound at all.What im trying to do is an application that would fire an event every time there is a change from one state to the other.

And I'm trying to write a program that read the data, filters the sections so that per line it does the bit before the brackets i.e. "S1" then a comma then the sections inside the brackets as comma separated values removing the double quotes and symbols I don't want etc. Basically dividing the separate S*'s onto different lines and separating the values with comma's. There are also other points which are a different letter than "'S" and the same to do with them to.

I have six textboxes, and upon button press it randomly generates six numbers, one in eact text box e.g. [43] [85] [93] [1] [0] [17]..i create another six textboxes and at the same time allocate these numbers in ascending/descending numbers.I am not looking for any codes whatsoever, as i love the challenge of VB.Net.

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.

View 1 RepliesI 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.
am writing an system application for a company that must generate inquiry id and order id automatically. Whenever a customer makes a new inquiry or new order by clicking the add button, an automatic number should be displayed in the text box and when it's saved, it should be saved in the database access.

View 19 RepliesI'm writing a super small interpreter in vb.net because i need to execute a simple (invented) language so the app understand it and do what ever it needs to do.Everything went well until i reached the control structures and the loops.So my question its, in a code that its executed line by line using a simple for each how can i match the "WHILE ;" AND "ENDWHILE;" and execute the code within it?
The first thing that came to my mind its kind of flag the line of the reader and read the content from that line until find "ENDWHILE;" and the store that to execute late, so keep isolating the code in parts until I've all parts and then execute it.But i'm not so sure how to code it or if my reasoning its correct.PD: I'm using regexs.
I did For each Loop in my combobox, but I noticed that it loops twice. When it reaches the last item, it loops back to the first item. I code it typically: For each itm As Object in combobox.Items
