What is wrong with this code? It is called in groups of four, and always seems to wind up with only two combinations:

[Code]...

It is returning random strings, but it seems to be returning them in a non-random order?

.net - Make Randomize Function To Randomize The Timers Intervals?

Mar 30, 2011

I cant figure out the code for vb.net that would randomize the interval of a certain timer. For each a = a + 1, there would be a different interval, and for each a = 1, a = 2, a = 3 etc. there would be a different text that will be shown on a label.

How To Properly Open A Image Using Bitmap Class And Dispose It Properly

Usually we can open a bitmap using this[code...]

the following code however keeps the Image File locked until the application is running, any suggestions how to dispose it properly. (So that no handle is left open )

Things i already tried: use dispose method of bitmap <= doesnt work (need to write implementation)
Using Block also doesnt work.

VS 2010 - Isolating And Randomizing Sentences

May 11, 2010

Basically I have two textboxes.
Textbox1: "(Hey|Hi|Yo)! My name is (John|Linda|Carl)"
Textbox2: Blank

What I want to do is to press a button and transfer the contents of Textbox1 to Textbox2. However, I want it to randomize the result by randomly selecting between the words in the parentheses. Now of course, the contents of Textbox1 are subject to change at any time, so I can't just add code for "Hey", "Hi" and "Yo". I need some sort of system in place that will generate random results no matter what I put in Textbox1. So I guess I have to search the string for "(", note the location and then search for "|" to isolate the characters in between as one word or phrase. Then search for ")" to determine the end of the randomizing and continuing normally until the next "(".

Asp.net - Pulling Data Into A RadioButtonList Including Randomizing ?

Jan 16, 2012

This is in ASP.net iwth VB.I have a quiz project that I've been assigned for work.This quiz project contains two main SQL Databases it pulls the info from. First is a Quiz table, which contains three columns: QuizID (Pri Key), Title, Description. This is where I declare the quizzes, indicated by the QuizID (1, 2, 3....etc)

The second table is the Questions table, containing the following columns: QuestionsID (Pri Key), Title, Answer1, Answer2, Answer3, Answer4, Answer5, CorrectAnswer, QuestionOrder, QuizID....The QuizID in the Quesitons table matches the QuizID in the Quiz table.Thus for QuizID = 1, it consists of all the questions with the matching QuizID in the Questions table. The CorrectAnswer I want to assign a simple value (1, 2, 3...etc).I need a way to take a set of questions (based on the QuizID) put them in some sort of table and randomize them (or rather shuffle them) so that each time this quiz is taken, it pulls all questions randomly, but not repeating any)...I then want the code to pull the question and coorepsonding answers to pick from in a radiobuttonlist. However, It only needs to pull the number of answers. Example, a True/False will only have Answer1 and Answer2. The other Answers will have the NULL value in it.

There needs to then be a way to go through each one of these questions that have been placed in the table (in that random order) using a "next" button. When a question and possible answwers are displayed, I alaready have code to keep the answers in the session to grade it at the end (using correctAnswer and selected answer.I have no specific way to bind the data to the Database. I have used SQLDataSource to make other connections before, but I don't know if this is the best way.

Randomizing - Code That Reads In Lines Of Tabbed Text

Jan 4, 2010

I have a piece of code that reads in lines of tabbed text. It is a game of who wants to be a millionaire. What I would like to do is get the game to incorporate random questioning.
The format of the text file is as follows:

Which record company did the Beatles create? (tab)Apple Records (tab)Sony (tab)BMG (tab)LiteFM (tab)Apple Records (tab) Which has the highest mountain? (tab)Mars (tab)Ireland (tab)Iceland (tab)America (tab)Mars(tab) With a set amount of lines. I want the program to choose each question randomly and not to repeat the question. I'm not sure how to incorporate it into the code.

When To Use Randomize()

Dec 31, 2009

I'm confused on when I should use the Randomize() function.It's my understanding that will give a new seed to the random based on the system clock, so should I therefore call it each time before generating a random number?I seem to recall reading once that it should only be used one time (like in the form load event), thus my confusion.

Randomize Repeats Same Number?

May 23, 2012

I've seen a few other people ask this question and have tried the responses that they have had with no luck.

I am trying to use the randomize command to generate a truly random number. What I am doing is reading an access table to get the number of records, then seed the randomize statement with that number of records with the top range for a random number. I then use the number to select the record I want from that table via it's ID number. My code for doing that is working great.... except that it is always calling on the same record each time through the loop. Here is the code.
