Forms :: Optimize Code And Lower CPU Usage?
May 14, 2009When my form first loads, it runs at about 30k CPU, but after about 10 minutes of use, it goes up to (and stays at) about 70k CPU.
What ways can i optimize my code to allow the CPU usage to stay low, or how can i lower it during the running of the program.
My most concerned areas of the CPU are:
1. I have a web browser, and when a user types in a url and presses go or enter, the CPU jumps about 4k:
Private Sub Go_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Go.Click
WebBrowser1.Navigate(OldURL.Text)
[Code]....
The second worry is when i open other forms, it boosts the CPU up aswell. the only code for this is:
Form.Show()
Receive Upper Bound And Lower Bound Of A Range
Sep 20, 2010Is there anyone who can tell me the code for the below? Receive a lower bound and an upper bound of a range. Also receive a number of random numbers to generate. You must validate
1) the numbers are integers
2) the lower bound is less than or equal to the upper bound
3) the number to generate is positive (i.e., > 0).
Generate this many numbers in the specified range and keep track of how many of each are generated in an array of counters. Once all the numbers have been generated, display in a List Box the number, the raw count data, and the percentage of how many times the number was generated displayed with two decimal places of precision.

Loading Images From Resource Into ImageList?
Nov 21, 2010I have about 100 PNG images stored in a Resource. Sometimes I need to have the same images in an ImageList, but I do not want to store the images twice in my application, so I add the images from the Resource to the ImageList during runtime when I need them.
Is there an easier way to do this than having 100 lines of code, like the small example below?
imgItems.Images.Add("A", My.Resources.A)
imgItems.Images.Add("B", My.Resources.B)
imgItems.Images.Add("C", My.Resources.C)

Loading Images With Different Filenames Using One Line Of Code

These images are imported in my resources under images as _0.gif _2.gif up to _7.gif. I could write code for each of the imageboxes individually but i prefer doing it in an array as shown below.

Creating A Custom Media Library - Loading Images For Rendering?
Jul 22, 2010i'm working on a project right now and I need to create a graphic library.The game I'm experimenting with is an RPG; this project is expected to contain many big graphic files to use and I would prefer not to load everything into memory at once, like I've done before with other smaller projects.So, does anyone have experience with libraries such as this one? Here's what I've came up with:
Have graphic library files and paths in an XML file Each entry in the XML file would be designated "PERMANENT" or "TEMPORARY", with perm. being that once loaded it stays in memory and won't be cleared (like menu-graphics)The library that the XML file loads into would have a CLEAR command, that clears out all non-PERMANENT graphics I have experience throwing everything into memory at startup, and with running the program running with the assumption that all necessary graphics are currently in memory.
