Suppose I have 3 vars:
dim a as integer = 5
dim b as integer = 1
dim c as integer = 10
What is the most efficient method of determining which variable has the largest value while using the least amount of code? I know this can be done with if statements, but there must be a more elegant way to do it.
I'm converted a VB6 project to vb.net using the convert tool.Now i have a few declares that included passing variables as "as any" which vb.net doesn't like and it seems you have to declare them as there correct type so i have the following,So i suppose , Long and Long
Private Declare Sub CopyMemory Lib "kernel32" Alias "RtlMoveMemory"(ByRef Destination As Any, ByRef Source As Any, ByVal Length As Integer)
and
Long again?
Private Declare Function CallNextHookEx Lib "user32" (ByVal hHook As Integer, ByVal nCode As Integer, ByVal wParam As Integer, ByRef lParam As Any) As Integer
I need to induce a variable amount of lag in vb.net. System should be noticeably slower. I can raise the CPU usage of the program with infinite loops and some variable creation/assignments, but how can I actually cause lag? I'd like to have an "InvokeLag" sub which will perform an action to slow down the computer, the faster the function is called the faster it lags. The function should be as mundane as possible, not modifying anything or doing anything to cause damage other than simple lag.
View 3 RepliesOkay so maybe i'm looking at this problem the wrong way and if I am please tell me but here goes.
View 3 RepliesHow can you trace the amount of memory used by each variable, process in a program? I tried CLR 2.0 but am not sure how to read the results. Are there any really good articles on CLR 2.0 that describes what I am looking for?
View 3 RepliesI'm trying to work out a program where you can set up a variable amount of timers (like egg timers). Each timer works independently of the other (you can stop a timer, reset another, and so on, and the rest are not effected).I thought of using a single timer and then creating a custom egg timer class to handle the countdown, store the current time, etc, and use a collection of these classes inside a timer event (at the tick, do a for each to reduce the countdown on the classes by some milliseconds).Then I got to thinking: all of these egg timer classes in the collection with the for each loop may cause some accuracy loss (say, I add 50 egg timers).
Does anyone think the accuracy loss for updating all of the egg timers would be too adverse? Should I try running them on separate threads (have not thought about how yet), or will that make much difference?
OK, after trying to get this working for a couple of days now I decided that I would turn to the experts here. I am trying to create a nested loop with a variable amount of nests. Let me elaborate. I have a program that first asks for the minimum and maximum amount of loops, I currently have a SELECT CASE statement that addresses each level of nesting individually.

I have a mesurement that could be any random value, just for fun well make that 2440mm i need to divde that by the industry standard of 610mm which comes out at 2440 / 610 = 4
Programicaly written NEWVAL = YVAL / STDVAL
NEWVAL (4) gives me refrence to how many instances I want to append a new line in a txt file I know that I want the first line to say 0,0,0 and the second line to say 0,610,0 the third 0,1220,0 the fourth 0,1830,0 and the last 0,2440,0, though this is easily achived with addition how can I automate vb.net to produce a new write line for each each instace of 610 if the YVAL is user defind.Put in simple terms half would be missing if the YVAL variable is double in length at 4880mm?

View 10 Replies(I'm using 2010 express), which includes, i think, very basic knowledge of coding. I have made a game in vb 2008 express before and it was a basic arcade game where you move your guy from the left to the right collecting points and dodging enemies that are randomly moving in the opposite direction that you are. Now I am attempting to make a sort-of user interface similar to that of the ps3 home screen, as a windows shell replacement app..
so far i have got what I am looking for in terms of moving between the menus, however the code that I have made seems very extensive for such a thing (in my opinion)..the question I am asking is whether there are ways of shortening the amount of code used, or changing it to be more efficient..if someone is willing to help, I will post my code, or upload my project (if given instructions on how to do so)

im trying to make a fast food program on which the user will input the amount that he has, then he will check on what he wants, by using check boxes. There are 7 different check boxes with 7 different amounts of money. I have the program somewhat finished (thanks for the people that helped me before) but theres still a couple of things that I still need to get finished but I dont know how to.I need to be able to get how much money the user has (this will be entered threw a text box, I think I accidentally messed this part up, because I cant get it to work right, (theres alreasy a permit amount of money in there and it needs to be what the user enters instead of the permit, 5.59, one) and this will be the maximum amount he can spend, then the user will check on the food he wants (and the program will add the sales tax also) then it will produce an answer saying if you have enough money or if you dont. But what im confused on is how do I get the users amount of money and make it the maximum mount he can spend and make sure it doesnt go over the amount that he has checked.[code]

The application should display the largest and smallest values stored in the array.

The only issue i have is to get the smallest number to show up.. mine just keeps showing "Zero".
I have an array of integers and I need to know the index of the largest number (not the actual value, just the index of whichever is highest).
However, if one or more indexes "tie" for the highest value, I need to have all of the indexes that share that high value.
I assume this function would need to return an array (since it could be one or more indexes), but I am not totally sure how to go about getting the more efficient solution.
