Now I want to know how to do the following:
1. Select a maximum size per file
2. Promotion system randomly choose a name (with numbers and letters - at least 5) Then the program will show me a link to a file after uploading (for example: [URL] in TextBox2.text)
I am currently working on a family project which is based on "Who Wants To Be A Millionaire?" show. There is a huge diffrence between the show and my project. My project is a christmas edition and the goal is not to get money or something, since I will not add it... Erhmm... Let me get to the point. I have already designed a layout and scripted some things. I have about thirty questions but I do not want them to always spawn in the same array, if you know what I mean. I want the program to randomly choose one of those thirty questions and NEVER choose the same question in the same program run. By the way, there are four options on my project: A, B, C and D. I have got everything, I just need a code.

I am going to create a windows form and add a push button (pretty simple right?) I want the push button to randomly cycle through about 10 pictures and display the randomly selected picture.
A few problems I am facing, 1) I do not know how to do do "randomization" in VB.Net and 2) I do not know how VB.Net would handle displaying an image, would it display on the form i am building or would it display in the default photo viewer for Windows?
i wanna make a program for my little brother, that allows u to input a name then to display a msgbox with pres coded phrases such as "your a good boy" or "your a bad boy". my problem is how do i tell vb to randomly choose between the two phrases, not keeping on choosing the same one?
View 14 RepliesI'm relearning VB.net just for fun, so consider me new at this. I'm trying to write a program where the user can input a list of names or numbers, and the program will randomly pick one of those names or numbers. So far, I can get it to randomly generate numbers based on what I put in the code, but I don't know what I should use for the user to input the data, and how to code it so that the program will pick from that data.
View 3 RepliesSo 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 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 am making an application that randomly generates numbers. I then have to find out if those numbers are even or odd. Then place them in the corresponding array ( EvenNumbers() or OddNumbers() ). Then display the random numbers array then the even and odd numbers array. I am up to the point where I have the generated numbers and can tell if they are even or odd, but can't get them into an array. I am trying to do it like this....

Below is a form which produces a graph, the idea is to produce 6 random numbers from a range (0,6) place the numbers in an array then use these numbers to produce columns on the graph, however at the moment it is using the numbers more than once, how can I get it to just use the values once only in the array.

How long it would take to generate all of the numbers between 1 and X randomly.
X=1,000,000 took 6 seconds, and for 10,000,000 took over a minute.
Does that sound reasonable?
Experiment
stopwatch start
count = 0
do while count < x
select a random number between 1 and X inclusive
have i selected this number before?
no-add 1 to count
yes -
loop
stopwatch stop
display elapsed time

what i need help with is, ive created a lable called lblFn next to the FirstName Textbox and would like this to be updated with "Please enter Characters Not digits" if a user enters digits in the textbox, how do i amend the above code to get this working?Basically whatever textbox a user enters wrong data in it updates the corressponding label next to it!
im a student still learning and im stuck. im writing a program that returns the ip address, splits it in to parts, and now i need it to return a string of letters for other parts to use. EX.
ip address 127.0.0.1 will look like ABG.XXX.XXX.XXA
( i would like to set 0=X so it is easier to pick out the actual
numbers)
I am able to split it and display each part and rewrite it to textboxes without the "." but i dont know where to begin to change the numbers to the letters i need.
I'm on VS 2008 I have one form contains many textboxes,when I write in one textbox (UserName) the letters and numbers should distribute to the other texts where each textbox has only one letter or number from the original text to get them ready to be encrypted.
What code I can use in text change event that takes the whole text and throw it in the other textboxes so each textbox has only one value ?
My listbox will accept any letter I add, but I can't get it to accept any numbers. I tried a case select for 1-100 and I couldn't get that to work either,

To complicate things a little, each combination needs to be different, ie. randomised but still according to the 'letter,number, letter' formula. There are plenty of examples of randomising strings such as passwords but I cannot understand how to achieve the above.
I want it so that when someone clicks a button it generates a code in the format of XXXXX-XXXXX-XXXXX-XXXXX-XXXXX I want them to be letters and numbers combinations
View 10 RepliesI'm brand spanking new to coding (as well as this forum). And I'm learning Visual Basic 2010 in School. Right now I am working on the following problem: "Use a masked text box to as a user to enter a phone number in a format as follows: (604)323-5819. Make sure you add input mask to the area code and phone number. Both the phone number and the area code are required. Then extract the area code and display it in a text box when a button is clicked." Here is my code, I've got it where I can input the number, and when the button is clicked (things actually appear in the text box!) however instead of getting the area code, I get "als" or alternatively if I put (0,3) I'll get "fals" I don't understand what I'm doing wrong or even where "fals" is coming from. Can someone please explain to me what I'm doing wrong? I've literally been at this since 4pm today and only just (midnight) able to get it to this point and I'm incredibly frustrated as to where these letters are coming from. [code]
