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.

VS 2008 Counting Down From 30 Mins?
Feb 7, 2010I've done what I thought was a lot of work with DateTime and Timespan but what I am trying to do now I cannot figure out. It seems simple enough but I can't think of the code I need to make it work >.<
Currently I am using a timer to tic on 1000ms to count down a timespan. However, what I would like to do is set a timer for 30 minutes. I would like to display the minutes:seconds of the timer on a label and perform actions when the minutes and seconds are specific values, say minutes = 5 AND seconds = 0 to perform an action when the timer reaches 5 minutes exactly.
My goal is to have a 30 minute timer that performs actions at specific times, then when the timer reaches 0:00 it restarts at 30:00 This seems like such a simple task but I cannot for the life of me figure out where to start.

VS 2008 Counting Occurrences Of Words In Array
Apr 9, 2009I am in a "survey of programming languages" course and have a professor who doesn't teach. There is no text book for this course.I am working a VB Form project to take a URL, grab the HTML source code, parse out all words, and count the occurrences of each word on the page. I have built the form, and written the code to parse the words and store them in an array. What is the most efficient way to count the occurrences of each individual word in that array (case insensitive), sort the results decreasing from most frequent, and display the results of the ten most used words. I will be displaying the results in two separate listboxes on my form. 1 listbox shows the words, and the other shows the number of occurrences.

Counting Rows / Columns In Excel Worksheet Using VB 2008
Mar 16, 2012This is my first time posting in a forum like this, so please excuse me if I accidentally break any thread rules (btw, where can i find these?). I am very new to Visual Basic and have been trying to teach myself as I create this program. I have experience with macros in excel so I do understand some of the coding, but definitely nowhere near being proficient. I am using Visual Basic 2008 Step by Step (Michael Halvorson) to teach myself.
I am trying to create some code in my program that will allow the user to open an excel file and then return the number of rows and columns in the worksheet. There will only be 1 worksheet in the workbook (since this is just a small part of a larger program I am writing). I already tested the code that will open the file in another program and it worked fine; the thing that is catching me is the row and column counts. I'm a bit stuck here and was hoping someone could point me in the right direction. Here is the code as follows: Code: I have another sub for a quit button which I chose to leave out. The last line for the MessageBox is causing me problems.
