1st. I want to programatically turn on/off the backlight on my laptop. I believe it can be done with the user32.dll, but I can't find the exact code.
2nd I want to programatically turn on/off my WiFi adaptor, just to interupt my internet connection for a few seconds.
Im using the Windows Media Player OCX in a program runned on hundreds of computers (dedicated).I have found out that when video acceleration is turned on to "full", on some computers it will cause the video to fail to play correct, with green squares between movies and so on. Turn the acceleration to "None" and everything is fine. This program is runned on ~800 computers that will autoupdate my program. So I want to add to the startup to my program that it turns off the video acceleration.
how do I turn off video Acceleration Programatically?All computers are running XP and at least the second service pack.It would take me ages to manually logg in to all those computers and change that setting so thats why I want the program to be able to do it automagically for me.

View 1 RepliesRight now I can add background music in my program by using this code
My.Computer.Audio.Play(My.Resources.Music_3, AudioPlayMode.Background)
I can also turn it off and change the music by using this code
My.Computer.Audio.Stop()
My.Computer.Audio.Play(My.Resources.Another_Music, AudioPlayMode.BackgroundLoop)
Is it possible to pause the music then if I resume the music it will just continue the flow? I mean if I pause the background music in 33 seconds and the music has 50 seconds and I resume it will just continue playing in 33,34,35 etc.. seconds?

View 1 Repliesi'm working on a game where when your character (in a picture box) collides with anthother charachter (also in a picturebox), the character disappears. i want the computer to generate characters as you play. I'm trying to figure out how the computer will know if the player character has collided with a computer generated character. as the computer generates characters it puts their names in a list box. what i'm not sure how to do is pull the names out of the list box and have the computer check the location property of the picture box with the name that corresponds.

View 5 RepliesWhy is it so important to turn option strict on? I admit I am not a professional programmer, but I have written a great number of useful applications...I am fairly well (although self) educated in object oriented programming... I even write programs for my business...I always have felt that I am missing some background theory that is probably really important (I have a grad degree in math, no comp sci)...I have never turned on Option Strict for any project I have ever written, and I guess I just want to know, theoretically why is it important?

And one more thing: Is it possible to have a vb app that uses http? E.g., sits on port 80 itself and can be accessed via local ip.

View 7 RepliesI wish to turn on the Single Instance Application choice in Visual Studio 2008 properties. To do so, I must choose "Enable Application Framework". When I do that, my ONLY choice is to choose a Startup Form, not a Startup object. This makes no sense to me. I have a tray application, and I check to see which form I should load, a logon form, or the main form. But since I am forced to choose a startup form, I MUST load the logon or main form to begin with. But I don't want to. I want startup code to determine which one to load first. So then I am playing with making the OTHER form invisible, even if the startup form, but that is a mess.
