Generate An Array Of 5 Random Numbers (with No Repeats)
Dec 12, 2009I'm trying to make a Bulls and Cows type game, I was able to do it fairly easily with javaScript, but VB is killing me. I can get the array 5 slots long with random numbers, unfortunately they're all repeats. when I try getting no repeats I run into infinite loops, exponentially increasing array lengths, and just plain old arrays with 5 numbers randomly generated, but with repeats.
I'm trying to do this with loops, in JS I did it using regular expressions
Here's an example of my code.

How To Generate All Real Combinations From String Array
Apr 2, 2012I need to generate all combinations (not permutations) in VB .NET, I've been search and all I found is for permutations (some says combinations but when I was try it, all are permutations).
What I need is to generate combinations from string array:
Dim data_array As String() = {"one", "two", "three", "four", "five", "six"}
I need that: If I say just 1 length, it must returns:
one
two
three
four
five
six
If I say 2 length, it must returns:
oneone
onetwo
onethree
onefour
... etc ...
twoone
twotwo
twothree
... etc ...
And continues til end with all combinations. If I say more length do it as well.

Bitmap Array With Dynamic Contents
Apr 2, 2010I'm working on a program that has to get a set of images and then scan them to find pixels that match colors in an color array. Anyway I think I got everything working but how to load the images in as bitmaps. See the images are dynamic, they change there filenames so I can't call them with a static call like Dim bmp2 As New Bitmap("c:button.gif").
So I am using a loop to feed the images into an array for bitmap but thats not working, anyway that I can do this as, right now the program gets all the filenames for the images from a text file that is sent in to us. All I need to do is have the program check each image for pixels that match our color list. But I cant get the images into the bitmap array.

Dynamic Array Of Byte Arrays?
Jun 24, 2009A project requires to allocate a varying number of byte arrays (buffers).
It would be ideal if the following definition would be possible:
Dim ArrayOfBuffers() as buffer(10000) as Byte
The byte arrays must be ordered sequentially because they have to be written to a file by efficient procedures destinationFile.Write(ArrayOfBuffer(3),1000,1000)
The number of buffers will change during program execution sometimes. Therefore it would be nice to be able to do a ReDim on the data structure when needed.
