VS 2010 Monitor Brightness. SetDeviceGammaRamp?
Jun 22, 2010
I have developed a small utility that can change the PC's brightness through the use fo a slider. I have achieved this with the SetDeviceGammaRamp API and the RAMP structure.As it is, it works. I am attaching the code here as well, so that you can see it works.Now, the problem is : At Form Load I am getting the current brightness settings for the monitor :
Private Sub SetBrightness_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
GetDeviceGammaRamp(Me.Handle, Ramp1(0, 0))
[code].....

I'm looking for a way to adjust the monitor's temperature. There's a program called f.lux that does this, but it doesn't get dark enough. The program I'm writing will be used on a boat and needs to be dark enough so that it's not blinding while driving at night.

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..

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've been investigating and experimenting with the code snippet on this page: [URL] - with some rather undesirable and wacky results being produced.
Why do I need this? I am attempting to adapt this snippet to suit my needs for a day/night system in the game I am working on. I am sure that the correct results can be produced with this snippet, but at the very least I need some guidance as to how I can achieve what I want.

I'm making a simple image editor in VB.NET, and one of the functions is brightness/ exposure.this is how I'm doing it:
For i = 0 To img.Width - 1
For j = 0 To img.Height - 1
Dim s As Color = img.GetPixel(i, j)
[code]....
where 2 is brightness which makes it twice as bright.Only problem is this doesnt seem to work well because it does it, but takes about 30 seconds!

I want to make a Small Traffic Monitoring Program for our house. Since in South Africa Internet is One of the many things that are way overpriced I want to monitor each computers traffic with a small Program since even when we are not at home for a day we might easily use 2 gigs of data. Somewhere a computer is downloading like mad?For a 4 mib(you only get 3.5 at most) line here Will cost you around R413(36 GBP/ 58 Usd) per month and One gig of data around R19(1.68 GBP/ 2.70 Usd) - R112(9.9 GBP - 15 USD).Ok enough Complaining. Each Computer in our house Connects to the internet either with lan or Wlan So is their a way to get how much traffic passes through one of those OR is there a way to monitor the total internet traffic regardless of how it connects to the internet ?

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'm using a series of 3 images within a picture box to create the illusion of a button being depressed when clicked. This is the code I use: Code
And this is the problem I have when doing these events: I am using Image lists, .png format, and I have made sure that they are all the same brightness in photoshop i.e. it is Vb that changes the brightness.

I would like to know if its possible for my vb.net app to monitor a 3rd party application that it starts. I'd like it to check every 0.5 seconds to see if the child app has a dialog box visible with a specific text string caption. If it does then I want to close my app but if isn't yet visible, keep looping until it is. I'm asking because the 3rd party app has "no event firing when the application starts to load and then displays the dialog so there is no way for the 3rd party app to report back" to my vb.net app when this is loaded.
This came from the Technical Support from the 3rd party app after I asked if using waitforinputidle() in my app would allow me to detect when their app finishes loading and enters an idle state (sadly not). However they have suggested that it might be possible to monitor their app for a specific dialog caption and then close my app but this is beyond my novice understanding just now. How to go about such a process?

I am "weeks new" to visual basic 2008 but I was hoping that someone might tell me how I can open an image in whatever type of "visible" graphics window (always positioned at: x=0 y=0); move to some "definable position" of interest x=(n) y=(n); change the brightness of that "individual pixel" by some "definable means of measure" from its original state; and save the new image as a separate image file?

[code]Seems to fetch data from my one and only internal IDE drive.The line objWriter.Write("Active: {0} ", queryObj("Active")) does not work if you change up the data in between the first set of quotes. Thus changing Active: {0} to Active: {1} causes an error that the Try Catch doesn't catch (this for...next is in a try catch).I assumed that the stuff inside the quotes was just text and could be changed to anything? Why doesn't the try catch catch it?Doesn't read a USB external drive when attached.i changed {0} to {1} and it crashes.

I have put together an app to monitor several directories. The basic principle is to replicate from a Master directory to a Shared directory when specific criteria is met (specific file types are changed, renamed or deleted within the Master directory)Everything seems to work fine with excpetion to MS Office documents. e.g. If I work on a .bmp and save it, it will trigger a changed event. However, with office documents (Word in this example), it appears to rename the MYDOC.DOC file to <freefile>.TMP then rename a different <freefile>.TMP to MYDOC.DOC. This would not be a problem if it was to trigger the Changed or Created event for MYDOC.DOC, but it doesn't. It wouldn't be so bad if the first TMP file was named the same as the second TMP file as I could mirror the process using the Renamed event.I can not filter out TMP files as we use TMP files within the Master directory, albeit for a different purpose.I would use an off the shelf produt, but the files need to be copied to different shared directories based on specific criteria so I can not seem to find a suitable product that fits my needs.
