And here is the actual code to do the task:

I will build a EXE file without form, this EXE file will turn off monitor, then invoke this EXE from command line.The turn off monitor code is below

Private Const WM_SYSCOMMAND As Integer = &H112

I want to know what about the MainHandle, because there is no the form in the EXE file (Me.Handles invalid), and only invoke the EXE from command line, in other words, there is no the invoke form (FindWindowA is invalid), how to write the MainHandle?

View 3 RepliesI am using Visual Basic 2008. However, the Report a Bug function does not work, which in itself is a major bug.While I am typing in the code editor, these annoying popups keep popping up and completely blocking my view of the code. I have no idea what these popups are showing and do not need them. I have not been able to find any way of turning them off. I consider this another major bug.
View 7 RepliesI'm tutoring a student in VB 2010 at a local college.i'm trying to explain to the student that he needs to learn the technique or art of knowing how to start coding in VB to accommodate a simple forms program.Is there a name or term that is used to describe the thought process a programmer goes through to convert what the user is expecting into the code that needs to be implemented to accomplish the task?A simple example is a form with a textbox on it and an OK button.When the user clicks the OK button, the program should check the textbox to make sure it is a number and not alphanumeric.The student I am tutoring has a hard time knowing what the first line of code should be to make that kind of test.He has a problem translating what needs to be done into code.I was wondering if anybody knows what that is called and if there is anything written about it.
View 15 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 RepliesCan I monitor the registry for changes similar to how sysinternals process monitor does it in VB? I have checked many different articles and C# samples but not come any closer to getting an answer, I would like to know if there an easier way (a VB sample perhaps)that you folks can share. Ultimately I'd like to be able monitor other things too like file system, processes etc but wonder most about how the registry can be done in VB...Would using system.management be a start? Or WMI? if so is there a nice VB sample..
View 3 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 3 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?

I am working on a little project for my phone creating some sort of remote to turn up/down my system volume via wifi. The phone will send data to a text field on the website lets say such as "vol up" and the vb app sitting on the computer will be constantly reading this text field for key words like "vol up", "vol down". when it see's a recognized command it reacts by turning the volume up and so on. 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.
