Sorry, it has been a long time since the last time I posted, but I did not have any idea of a project. Moreover, I had exams.Anyway, I am now facing a problem in programing a 'Sudoku' generator. However, I had an idea to solve it. Unfortunately, in this idea I need a code to pick a number in random other than:

View 2 RepliesI need my code to be able to choose 5 random files from a folder. I was hoping I could instantiate the Scripting.FileSystemObject then grab the target folder as an object and do something like FolderObject.Files(12).Name but apparently that's not doable. What I did works, but is sloooow:
FS = CreateObject("Scripting.FileSystemObject")
Folder = FS.GetFolder("c: emp")

I made a program to make a random name up from 2 textboxes on my program ( a firstname textbox and a lastname textbox). But the problem is that I'm just getting the names in order they were put in. I was using this code
Dim fname2 As String = fname.Lines(F)
Dim lname2 As String = lname.Lines(L)
and once it generated the name I would put

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.
View 3 RepliesI'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]......
View 9 RepliesThe class Random is out right defective. It always produces the same random numbers in the same sequence. Things I have tried so far is every kind of seed you can think of as well as Randomize. The result is that I always get the same random numbers in exactly the same sequence.
View 4 RepliesI am practicing using the drawing commands, and have gotten a grass background and black happy face that moves around the background.It's a 10x10 grid of 50 pixels.I want (at the moment, when i press enter) it to generate a random number of trees (15 ~ 25) at random locations on the background. The program doesn't freak out about anything, and the variables seem to be right (using stop commands) but it's not drawing anything. Here is the code for the "GenerateTrees" command I have for when I press enter.
Private Sub GenerateTrees()
NumberOfTrees = Int(Rnd() * 10) + 15
For i = 0 To NumberOfTrees - 1

View 3 RepliesI 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 Integer (1 to 100)
-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.
VS2010 (SP1) / .NET 4 on Windows XP. The question is simple, the answer; not so much. When generating a salt, should the LENGTH of the salt be random, fixed or a random number within a (min/max) range? I am using RNGCryptoServiceProvider to generate the salt, just unsure of the length of the salt.
View 12 RepliesPossible Duplicate: Which language should I pick up: VB.Net or C# I'm trying to make a descision on learning VB.NET or C# as my first .NET language. I'm aware that bith languages can achieve the same things since both ultimately use the .NET framework. I'm also aware that C# has a similar syntax to both Java and C/C++, so I definitely see the benefits with this.
But how about the future of VB.NET? Will it be maintained in the years to come?I do know a bit of python, so would that make C# easier to learn?

Which language, VB.Net or C# is the best language to choose for development right now? Needing users to have the .Net framework is something that I see as a drawback to Vb.NET, but what are the pro's and con's of each language? What can be achieved with one but not the other?
View 1 RepliesIs there a standard .NET control for what I call "a two pane picker", or do I have to code it by hand?
Two pane picker:
The left pane has a list of items. The user can pick items from the left pane to put them in the right pane using buttons between the two panes. Picked items in the right pane can be reordered with buttons.
An example of the "two pane picker" can be found by right clicking the Quick Access toolbar in Word 2007 and clicking "Customize Quick Access Toolbar..."
Note: If applicable, VB.NET answers preferred, but C# answers are acceptable too.
I have written a program in vb.net 2008 (using .net 3.5). It's a decent size program. One part of this program is to access an online database and encrypt/decrypt files. To access db I use a hardcoded password. To encrypt/decrypt files I used a hardcoded key. No matter what I do I would need to hardcode one of the two things at least. For example: even if I store database password in an encrypted file I would need to hardcode key to decrypt it. Or vice versa. So after doing some thinking I figured that I need to obfuscate my code so that at least these hardcoded elements/values wont be visible easily. Infact to test, I used a program to disassemble my program. And to my amazement, it showed me every line of code in my program. I felt as if my entire code is pasted in my exe.
Thus I need to obfuscate my code. See I do not need too advanced settings. My program is not among the top shareware programs or super popular that I need very high security. But I need enough security so that my basic code, variables and sensitive information (password etc) is not visible. Please help me choose a good obfuscator which will do the job. It should not be too tedious to use and should be sufficient for me. Plus it should be trusted and secure. I mean I don't want my application to crash or be unstable after I obfuscate it. I have downloaded trial of .net reactor from Ezriz and it seems to be fine. What do you guys suggest? I cannot affort something over $200.

Would you use this snippet to retrieve a List(Of Integer) containing all Id's:

Or rather this one:

This is not a question about whether to type cast the Id column to Integer by using .Field(Of Integer), CType, CInt, DirectCast or whatever but generally about whether or not you choose Linq over forloops as the subject implies.
For those who are interested: I ran some iterations with both versions which resulted in the following performance graph:
The vertical axis shows the milliseconds it took the code to convert the rows' ids into a generic list with the number of rows shown on the horizontal axis. The blue line resulted from the imperative approach (forloop), the red line from the declarative code (linq).

What I want is an SQL engine that works in a server/client environment, where i also can backup the database files from disk.
