View 1 RepliesI found many solutions in C++ however they seems fail to satisfy my requirement. I need code to turn off monitor when i'm away and if i want it to turn on, i must type specified key instead of any key press or mouse movement as usual.

And here is the actual code to do the task:
PostMessage(Me.Handle, WM_SYSCOMMAND, SC_MONITORPOWER, 2&)
This puts the monitor into standby. Can I please have some help to modify the code to turn the monitor off, and also the code to turn it back on.
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 Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd As IntPtr, ByVal wMsg As Integer, ByVal wParam As Integer, ByVal lParam As Integer) As Integer
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 1 RepliesI have tried to create an amortization program The issue that I am having is that the program wants to print the same page over and over again. The first page of the printout runs through the "While loop" appropriately, but when the second page starts printing, it repeats the information that is on the first page. This is true of all subsequent pages I have included the printing portion of the code.

Right 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?

Can 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..

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 2 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'm unsure if this should be in Office Automation or here, but I opted for here because I'm creating a VB.Net program to handle all of the office automation and my questions are a combination of the VB.net portion and some of the VBA formatting. At a high level I receive a file in email, put the attachment in a monitored folder, import the text file to excel, format the excel, and then email the excel file to a list of recipients. [code]Obviously the items above that are not complete are the bulk of the work, but I wanted to get some advice on what some of you think would be the best way to approach something like this. The import and formatting of the file are causing me some problems because I just can't decide what would be the most efficient way to do this. Having a template excel that contains all of the formatting already done for me and attempting to transition the data to this document (no clue if/how I can do this). Is it even feasible? Have the template already created and then import the text file to a new excel file, then transition that data to the excel template?
Something I thought about, in terms of formatting the document, was to record a macro of me doing all of the formatting that I'm going to need and then attempt to convert that macro into my vb.net code, but I'm not sure if that will work. I will need to verify that the text file comes in the EXACT format every time correct?
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.
