C# - Random String Function ?
Jul 31, 2011I've made a function in C# to create a random string, but I wanted to convert it to VB.NET, unfortunately my knowledge of Visual Basic is much less than my knowledge of C#.
Here is my VB.NET function:
CODE:
As you will see, its not much different from my C# version, except that since VB can take an optional parameter, I allow the user to select what characters to use in the string, or just use the default ones.
Here's the C# version of my function:
CODE:
Again, there's not much different, but the part I'm really struggling on is the conversion between what is the 12th line of VB code, and the 13th line of C# code. I didn't really know how to convert it to VB.NET (as I said, my knowledge of it is very limited), so I used an online converter. The result of the online converter runs with no errors, however when I try to call the function, no string appears.
In short, this C# code works fine:
CODE:
However, this VB.NET code doesn't work:

How could I fix my VB.NET code?

View 5 RepliesGet The Vb Random Function - Basic Winapp Application
May 13, 2010I must say I don't get the vb Random function. Try making a basic winapp application, but a button named Button1 and a few (around 10) labels on the form. Then add the following to the forms codebehind:

Public Class Form1
Public Function RollDize(ByVal iDize As Integer) As Integer

Now, if you click the button, you will see that all the labels get the same number. However, if you step through the code in debug, the numbers are random.

Use The Randomize Function To Generate A Random Number Between 1 And 50
Mar 29, 2010I need to use the randomize function to generate a random number between 1 and 50 for lblNum1 and lblNum2, ensuring that lblNum1 is greater than lblNum2, otherwise the randomize function needs to run again for lblNum2. I need to ensure that the user has selected an option from the gbCalcType and cboGrade first, and then the randomize function should run when the user clicks the button named btnBeginGame.

[2008] Make Sure That Each Call To The Function Is Much More Random?
Jan 15, 2009I have a function called DieRoll. In the function I have the following setup.
Dim objRandom as New Random
Dim intRoll as Integer
intRoll = objRandom.Next(1,7)
Return intRoll
Everything works as expected as far as generating a random number (1 - 6) is concerned, except for one problem. If I have a series of calls to the function one after another, the numbers come up the same. Is there a way to make sure that each call to the function is much more random?

Function To Create Specific Amount Of Random Numbers
Apr 5, 2009I am currently taking a introductory level class to vb.net. For the assignment it asks to create two functions. One function should create a random number within a given range. I have completed that part. What I am having trouble with is the second function. It wants the next function to use the previous function three times so that it displays 3 separate random numbers within a given range and display it in a D2 string format.
View 1 RepliesMake An App Where Computer Generates A Random Number Using A Function?
Nov 25, 2010I'm supposed to make an app where computer generates a random number using a function and then the user has to guess the number. If they get it right, they see a picture.... If they get it wrong the loop keeps going until ten guesses are up.. I'm running into quite a few problems...
1. I don't know how to tell if the photo will show up if the number is right because right now I have it set to false in the form, so it dosen't show up but in my loop I included the code that SHOULD allow it to show up if both numbers are the same.... Not sure if this is correct...
2. I have a textbox that is supposed to keep track of the number of guesses but the message automatically becomes Game Over and the guesses go up to 11 as soon as I click the Are You Right Button?
3. When I try to debug, my app freezes and I don't know why...

Creating A New Random Generator Each Time Should Reduce The Number Of Random Repetitions?
May 26, 2011I've read numerous posts and threads about random number generation, but I havent' run across this.If I generate a bunch of random numbers, the results are radically different if I create a new Random generator for each number than if I use on Random generator for all the numbers. The results are much more consistent and evenly distributed if I use the same Random generator.I would have thought the opposite,because creating a new Random generator each time should reduce the number of random repetitions, if a different time slice is used to create the random number.[code]......

Nov 24, 2009I don't take programming lessons at school or anything, and I'm starting to (try to) teach myself about random things.Currently I'm making an app that has 3 functions:

-Random Answer (Yes or No, similar to a coin flip)
-Random Dice Roll (1 to 6)
How would I go about doing this?At the moment all I know about random numbers etc. is that I will need to do something along the lines of Dim dice As New Random or something like that, but, like I mentioned, I have no idea.I am well aware of the DIC rules that you won't write the code for me/do my "homework(?)" for me, and that's not what I'm asking.
How To Pass A Function To A Function Is Functors/function Objects Avaiable In VB2010
Oct 12, 2011I want to make an numerical integration method with takes in an analytic function and integrate it over a specific interval. For the numerical integration procedure I want to use some procedures in nr.com. The problem is that these are programmed in C++ and they uses functors to pass a function to the integration method. How can I do this in VB 2010?
I want to initialize the function (i.e. set a=1,b=0 for function y(x)=a*x+b) and then pass the function to the integration method. Then when the integration method call the function it only calls the function with one parameter (i.e. x since a,b is already set)
What is the best way to do this in VB2010?I want to make a general integration method where I can pass any single valued function and integration limits.
I have just started using VB, and from what I have found so far it seems like the tools you have is
- to us a delegate for the function
- to use a lambda expression for the function
- send a pointer/adressOf
- to create a function class/structure and submit this to the function
As for now I am most inclined to create a function-class. But I am not really sure how.F.ex. I make different classes for each "uniqe function" I want to integrate, but how can I pass them to the integration function when I need to specify the argument type in the integration-function-call?This seems like a basic problem which applies to many Math operations, so I think it would be very useful to clarify this.

View 1 RepliesSetting A Variable To Accept The Result Of A Function By Calling The Function With Many Parameters
Feb 17, 2011I'm currently working with a client's VB.Net code, which was developed for them by a small development shop a few years ago and which they purchased and have been maintaining and uprgrading since. This client's primary developer is out on indefinite (likely permanent) medical leave and I'm now filling in until they bring in a full timer (as I'm a contractor here). My current task is to add some functionality to a the VB.Net code they purchased. I'm finding practices and techniques in the code that absolutely baffle me and can't make the code do what I want. I'm starting to wonder if it's me and was hoping to get some thoughts on the code I've encountered.
For example: Setting a variable to accept the result of a function by calling the function with many parameters, clearing the parameters in the function, setting them to some value, calling another function with those new values, then never using the values returned by the functions. I'll add a code snippet in the first comment since this is already getting long.
