View 3 RepliesRemove Repetition From If-else Statement?
Jun 2, 2011I have written an if...else statement which uses an array myArr and a string myStr as follows:
If myArr.Length > 0 AndAlso myArr(0) = "-1" Then
'Do stuff 1
ElseIf myStr= "xyz" Then
'Do stuff 2
ElseIf myArr.Length > 0 Then
[Code]...
It works exactly as I need. But It looks really confusing, mostly because the array length is checked twice. There must be a clearer way to write it, but I can't think of one. the order that each statement is executed is crucial. i.e. Stuff 1 has priority over stuff 2, which has priority over stuff 3.
VS 2008 Key Repetition Speed
Nov 20, 2009Say you press and hold down a letter on your keyboard. The first letter gets added, there is a delay and then it repeats quickly on screen. Is it possible to skip this delay and go straight to the repeating part? I realize this might not be a visual basic question as much as a windows question, but if there is some way of toggleing it through my program, or using a workaround, i would like to hear the alternatives ^^ Setting the windows setting to fastest still has a small delay and others users would still experience it on other computers.

Event Addhandler, RemoveHandler Repetition Conundrum?
Apr 14, 2010I'm getting a bit more fluent in VB.Net, but am still a bit green around the edges in certain aspects. I'm creating custom controls, and am starting to rely heavily on AddHandlers to manage them.Until recently, I didn't realize that you can add multiple event handlers for the same control and same address
[code]...
The above code would create 10,000 copies of the same event, and if I would click on combobutton1, the event would fire 10,000 times. I only need to fire the event once, but sometimes my code is a bit circular, and there may be an instance where two or more addhandlers are designated for a given control and address. Is there a way to have a loop on my custom dispose event where it would look something like:

Or better yet, remove all events from a control(On a side note, is there any way in the debug mode to see all the active events attached to a control?)

Asp.net - .NET Combination Of For Each..Next And Do..While?
Mar 21, 2011I have an array like so:
Dim classes() as String = {"FR%", "SO", "JR", "SR", "SR5"}
I need to loop through these values like so:
For Each value as String in classes
Next
Problem is, I have a If..Then..Else clause inside of this For Each..Next which says something to the effect of:
If actual_class = value Then
txt.Text = "Welcome"
Else
txt.Text = "Goodbye"
When I run this, unless the individual is the last value in the string array ("SR5") they are going to get the message "Goodbye"...so, I need somehow to both iterate through each value like is done with a For Each..Next loop but also break out of the loop once it hits the student's class, like a Do..While loop - so that their value doesn't get overrun by the Else clause.

Add Every Combination Of List Of Numbers
Nov 1, 2010VS2010
VB
I would like to be able to add every combination of a list of numbers to determine which combinations equal a specific result.
Simple Example:
List: 2, 4, 6
Result: 10
How many and which combinations of numbers result in the number 10? The correct anwser is only one which is 4 + 6 = 10. The example is simple but the actual list may contain as many as 10 - 15 decimal numbers.
I have thought of the following as a possible way of checking each combination by using binary:
- There are 3 total number so the possible combinations would be:
123 - Three numbers
000 - Add no numbers
001 - Add the last number
[Code].....
However, I don't know how to actually match up the bitwise bits to the numbers in the array to actually add. Example:
101 - I should check if 2 + 6 != 10 per the example above so this wouldn't satisfy the result... does this make sense? The answer would be 4 + 6 = 10.
how to check and add all combinations from a list of numbers to determine if the result is a specific number?
