Jul 25, 2009I need to draw 100 lines between 100 semi-random points in a 800x800 pixel square on the screen.
I've been using the built-in drawlines & drawrecangles functions inside of .NET, but my drawing gets erased everytime the form paints.
So, I've been thinking about perhaps drawing to an in-memory bitmap, but I'm not sure if that's a good solution.
Find A Pixel Color On Screen?

Screen Sizing - Max=stuck - Won't Get Off The Max Screen Size
Feb 11, 2011VB.net / VisualStudio8 I have an application I've written that's been very stable. I had it set to exactly 1024x768 resolution, and to windowsstate=maximize (I think that's what it's always been).
I recently started coding to give the user the option to use the 1024x768 or to have the program detect the max size of the screen and use it.
That part works great... I'm using:
Dim MonitorWidth = Screen.PrimaryScreen.Bounds.Width
Dim MonitorHeight = Screen.PrimaryScreen.Bounds.Height
Me.Height = MonitorHeight
Me.Width = MonitorWidth
What I'm baffled by is that the application now won't get off the max screen size. It's using the max of the screen, even when I do not call the screen resizing code above. I'm trying to give the user the option of the application only taking up 1024x768 (and placed up to the top left) or maximizing the application using the full extents of the screen.
VS 2010 Compare Pixel Range On Screen To A Saved Image?
Dec 1, 2011We stream the BBC news channel through a laptop hooked to a PC in reception for our clients. Annoyingly the stream is interrupted randomly (the line isn't dropping, it's the BBC's problem). Therefore when it's interrupted we get an error screen appearing which we have to go and manually refresh to get the stream back playing.
My intentions are to build an app which will be run alongside (silently) the stream monitoring intermittently a range of pixels. If the range matches the error screen that I mentioned previously then I'd call "Esc" to exit the full screen and then "F5" to refresh the browser and finally a double click on a specified coordinate to bring it back to full screen.
Problem: I've been doing some googling and so far have only seen related posts where the comparison is between two saved images. Due to this I expect the answer to be "Take a screenshot every now and then, compare, return result".

View 2 RepliesProgram To Detect Change In Selected Pixel On Screen - Memory Leak
Mar 21, 2011I am fairly new to visual basic and have written this program to detect a change in a selected pixel on the screen. When the pixel changes, a sound plays every x seconds. It works fine but after a few hours of operation a possible memory leak causes it to either crash the program or the PC. I have watched the process and I can see 4k added to it every 4 seconds or so. Where this memory leak is coming from?
Here is the code:
Public Class Main
Public pointx As Long
Public pointy As Long
Public areaselected As Integer

Size Of RTB On Screen Vs Print Size
Mar 16, 2011I have an RTB. Actually it is a RichTextBoxPrintCtrl as per KB 146022 but I don't think that matters.
I am printing the contents of the RTB on a label. I have determined the appropriate margin settings to cause the contents of the RTB to print on the appropriate label (there are 4 per sheet). That all works.
But I want what the user sees on the screen as he types to match what prints. So if he types three lines of data he gets three lines on the label. Also, if scroll bars appear, that is a clue that he have filled up one label. By trial and error I got the size of the RTB just right using the default font (MS Sans Seriff 8.25).
But when I or the user changes font size, the on screen display no longer matches the printed label. The label prints properly but it is not an exact representation of what is on the screen.
Is there a way to fix this problem so the screen representation of the label is always correct even when the font changes.
Keeping A Total - Size Of Pizza Which Is A Combo Box (CmbSize)
Apr 7, 2011Anyway I am writing a program to allow the user to enter:
-size of pizza which is a combo box (CmbSize)
-type (thin crust or standard) of pizza which is a combo box (CmbType)
-pizza choice (spicy chicken, maryland etc) using a checked listed box (ChkdListChoice)
The problem I have that will probably be simple to a lot of you who are using this language frequently is that I simply want keep a running subtotal of the users choice. So for example the user chooses 8" Spicy Chicken - 3.50, then they press the BtnAddToOrder button to output it to the Textbox (TxtPizzaChoi). When the user adds the next pizza I simply want the previous pizza price to be added to this one giving a new subtotal. I have not made the price change if the user changes the size to 12" spicy chicken, the price is still 3.50, simply because I think this could make it more difficult to me and I don't have lots of time to work on this. My declarations are not all in use and i may not need them by the way.
Heres the code:
Public Class PizzaChoices
Dim price As Decimal
Dim topping As Decimal
