VS 2008 Random - New Character Out Of The String And Then Remove The Character From The List Of Characters
Dec 12, 2010[Code]...
For each character of this string I want a new character out of the string and then remove the character from the list of characters that still maybe used for other characters. It may not get the same character, you could basically just call this encryption, but it's not what I am making. I don't want to waste my time doing this one hour while VB can do this for me in <1 second.

How To Generate A Random Block Of Number Of Cells In Two Dimensional Space
Nov 25, 2009I am using VS2008. I worked on this problem for a time, but I was not successful doing it. Below is the VS file.I need to produce a grid of cells and have some random features as shown below which is an example of a world of (500 x 500) units (or any other size and grid size). It contains three areas (of 11 cells, Value of each cell = 108), two green areas (of 8 cells, Value of each cell = 137) and one river. The start point of the river should start from one of the world edges and finish to another one. Please note that number of feature could increase or decrease according to user inputs.The question is, how can I produce these features randomly? To clarify the question, I will read the number of areas from a form. I need these features so that the number of cells should be distributed randomly beside (attached to) each other in the world. The rivers occupy one sequential grid line. My problem is how can I randomly generate the features according to number of cells??
