VS 2008 Draw Directly On The Screen (not On A Specific Window) Just On The Screen?
Jul 1, 2009
I send a message a while ago and no one answerd, how can I draw directly on the screen (not on a specific window) just on the screen, neither if it's on the desktop or anything else.Is there is any option to bring up the switch between applications window (Alt + Tab), I don't want to use sendkeys because the user need to keep the key down and I just want the user to select the application with his mouse.
asking something like this i know it get's asked alot but i haven't found any code for this or i didn't look good enough. My internet is super slow so it is hard to browse the net , Anyways i want to draw on the screen just like when you draw on your form with graphics how would i accomplish this ? if anyone could provide some code or a link that shows a little about it that would be great,
BTW this issue occurs in any MS office program when the VB.Net (or even VBA) is processing information.Example: In Excel, a worksheet is displayed on the screen. I start either, a VB.Net or VBA procedure and within 30 seconds the Excel worksheet (previously displayed) blanks out. In both VB.Net and VBA,ScreenUpdating = False. My expectation is that the previously displayed screen would stay static as if I left my desk to get a cup of coffee; came back and the same ole Excel worksheet was still there?Of course, setting VBA Screen Updating = False accomplishes two goals: 1) speeds up processing and 2) saves the user from seeing unnecessary "garbage-processing" steps.Why does VBA or VB.Net ScreenUpdating = False not freeze the screen at the time of its invoking?
A way to scan to whole screen, and find a specific color on it - and after that move the mouse over the color.
This is what i would like the process like, so you guys can have a better idea:
1. A timer that scans the whole screen after a specific color every 5 seconds.
2. When the color appear on the screen, it'll move the mouse to the x, y.
3. After that I'll run some code (i'll hopefully find out of that myself)
I actually don't care how the color should be found. If it's a RGB it will be 255, 209, 102 it should look after. Or maybe it could scan the screen after a matching bitmap. And it's not just 1 pixel I want to find the color of, it's the whole screen I'll like to have scanned for the color, and if the color is found - the program should react.
I have a bit of an issue here. I made a "Colour picker" dialog in my program with which you can pick the colour at the mouse. It is a simple topmost form with an OnPaint handler used to draw a coloured border around the cursor:
It uses a transparency key to make the non-drawn parts of the form transparent.
It uses the following code to prevent the mouse from clicking through the screen:
It sets Layered to True and Transparent to False. This works in Windows 7, but on a XP machine it fails. When moving the mouse the event does not go to the forms' event handler and you can just click through. For a screen region selector I simply made a screenshot, but I want the Colour Picker to remain updated. (just in case you want to get the colour of an animated control)
How can I get this to work on a Windows XP machine?
Okay: I've been searching the threads and MSDN and elsewhere and either its not there or I am simply not understanding what I am finding.I have an image which at full resolution is larger than my screen (actually it is larger than any screen). I want to be able to look at parts of it at full resolution in a client area that is the size of the entire image at full res; that is, I want the window to exist without any scroll bars and want to be able to examine different parts of the image by repositioning the window on the desktop.
In general, I've run into trouble insofar as windows (or maybe VB) won't let me make my window any larger than my operative desktop (although interestingly it will let me place the window to the North-West of my visible screen). What it won't let me do so far is to grow my window any larger than my desktop.
So far I have noodled a couple of different possibilities, in descending order of preference:
(1) Find some way to exempt my window from the limitation that it be smaller than the desktop;
(2) Virtually increase the size of my desktop so that it is as large or larger than my image (i.e., find some way of exempting my desktop from the limitation that the desktop represent the dimensions of the screen/monitor -- understanding that those two are not the same);
(3) Simulate a multi-monitor configuration (I'll probably need at least four); or
(4) Actually configure my system for four+ monitors (I don't even know whether that's possible, but its certainly not my first choice).
Does any one have any other ideas or suggestions as to how I ought to proceed?[URL]..
I have a button btnRegEx that when pressed shows a ContextMenuStrip, similar to the '>' button in the Find/Replace dialog in Visual Studio when you are using Regular Expressions. I have a ContextMenuStrip cms which I show using its Show(x,y) method.
At first I was simply setting x and y (the location of the ContextMenuStrip) to some point next to the button, but I noticed that when the button is close to the edge of the screen it goes off screen. I wanted to prevent that so I built some logic into the x-y calculation. When the ContextMenuStrip width is larger than the 'remaining space left' I simply show it more to the left. Same for its Height of course. I am using the Screen.GetWorkingArea(point) method to determine the 'remaining space left'. As I understand it, it returns the working area closest to the point you specify (to which I pass the button's location).
As long as I stay on my first monitor, it is all working perfectly fine. The problem occurs when I move the form to my second monitor. The contextmenustrip is still showing on the first monitor for some reason...
Here is the code I am using:
vb.net Private Sub btnRegEx_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnRegEx.Click Dim p As Point = PointToScreen(New Point(btnRegEx.Left, btnRegEx.Top)) Dim x, y As Integer
[CODE]...
I have noticed that when I click the button when the form is on the second monitor, the buttons location (p) is calculated with the first monitor's top-left corner as (0,0), even though it is on the second monitor. This way, the GetWorkingArea function returns something like 1280, while the buttons x-location is something like 1700... So, how do I get the buttons coordinate relative to the actual screen it is on, rather than the entire dual monitor screens as a whole?
how to Draw text directly to the screen - effectively overlapping anything underneath it - but have it out side a form area! I would really like to have no user interface at all if possible I know what I wanted after recently using FRAPs.
I'm putting together a small program in Visual Basic Express 2010, and part of it is to take a delayed screen shot.
I've got the main code working, I've got Visual Basic delaying taking the screen shot with System.Threading.Thread.CurrentThread.Sleep(5000), but what I'm looking for is a way to draw directly to the screen the number of seconds remaining.
You know how in Windows, in the Display Properties under Settings, when you click on Identify you get a huge number displayed on each monitor?
I'm trying to recreate that, with the number counting down until the screen shot is taken, giving the user plenty of notification to get their required applications in focus for the screen shot.
Is it possible to do this? Or is it something that will take a heck of a lot of coding?
im using vb.net to open IE and go to a website... i can figure out how to size the window, but not change the windows location on the screen... how can i make the IE window position always 0,0
Dim oIE As Object Dim hWnd As Long oIE = CreateObject("InternetExplorer.Application")[code].....
I've inherited a project in VB6.NET 2008. There is a Panel control where graphs are drawn along with titles, axes, legends etc. What is drawn on the panel is also printed WYSIWYG (on a print command, of course) The problem I have is that the code for printing is entirely separate to the code for drawing. I want to merge the two so that common code is used. I'd like to work in the same units for both, which means setting either the pixels per inch for the Graphics object for the printing (so I can work in pixels) or doing the equivalent of the opposite so I can work in inches (printed inches, not screen inches).
I'm writing a simple program that takes a screenshot of tab1 of the GUI, then takes a screenshot of tab2, then tab3, etc. I've got the screenshot code down pat, but the problem with my current code is that it's taking the screenshot of each tab before the screen has a chance to fully redraw, so the resulting images are screwed up.Is there a way to get the program to wait for each tab (and all the controls in it) to be fully visible before each screenshot is taken?I'd like to avoid using a timer for this, as the screen redraw speed will vary depending on the user's computer, and the contents of each tab, etc.[code]
Now I'm creating at app in VB (Microsoft's, Visual Basic 2010) which will be in full screen but I want to know if I can put all my content in the centre of the screen. At the moment it's at the far top, left of the screen. When the screen size varies I want it will stay in the middle for all shapes and sizes. Like :
I'm trying to get coordinates on my screen by holding down my mouse and placing it over different parts of the screen. I'm using the mouse_up and down events in a button to kinda simulate the mouse being held down. The problem I'm running into is that anytime I go past the button's bounds, the coordinates I want stop. This is what I have so far:
I have created a GUI and have set my 'Form1' window to match that of my PC monitor ( 1280x1024 ). However when i move the project to work on my netbook, the screen on my netbook is only 1024x600 and half my GUI is missing. Is there any way i can adjust my settings so that my 'Form1' GUI will auto adjust and display in full on both screen when i move the project back and forth?
I'm coding a splash screen in VB.Net that displays for 3 seconds then shows a login screen. But the splash shows up even when login shows and I have told the splash to hide. Here is my code:
im about to develop a small appliacation for a bet system, which needs 6 screens, each screen will be a touch screen for each client... the application will be running in one computer only just with 6 screens. my question is does anyone knows how to control each screen separately?. somethign that would allow me to output each forms in different screens would work fine.
Say I have microsoft paint open. How can I tell the program to focus on microsoft paint, so the coordinate (1,1) is the corner of microsoft paint instead of the corner of the whole screen? And also when I say focus, I mean it gets pulled into front of everything else.
I have incorporated a 3rd party program in my project to run at certain times, but when this 3rd party program is ran, it opens an instance of IE every time it is ran. I dont want this ie open when my program is running. So i was hoping to incorporate code that will close that IE page when it opens. It has the same Title every time it opens. is there code that can sniff out the title of an IE browser window and then close it?
I am making a program that will put a black mask over an application (like a full screened game). This black mask will fade in and out, depending on certain criteria. Is there a way I can do that with VB? It's to help me dim my monitor without having to push anything.
