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:

In my vb.net project, i use to add Datagridview dynamically into a tab control. tab pages's autoscroll property is set to true. i calculated the gap between consecutive DGVWs and pass the parameter in the location as like this. [Code]
supposing if i want to 7 DGVWS, say 5 DGVWs are placed finely in expected gap until i do the scrolling the vertical scroll bar. whenever i scroll the bar(vertical) to the downmost end and then again add DGVW into the tab page. unfortunately the 6th DGVW is placed somewhere down and the gap between 5th and 6th dgvw is enormous difference. what i understand is whenever the scroll bar is brought to the bottom most end, the drawing point is taken as the current top view. i don't want like this. Is there any setting needs to be take care.

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?
View 11 Repliesit is designed to be able to interact with foreground windows and display certain bits of information as each foreground window is displayed. The foreground window will most of the time NOT be a windows form so this makes things that bit more trickier for me. The program below doesn't produce any errors but the problem arises when I try and get the X, Y coordinates of the cursor, at the moment when ever the cursor is moved around I get a very long number as the X and nothing returned for my Y. I find I can set the X,Y coordinates to anywhere on the screen, can also get the foreground forms title,it's RECT coordinates but need to get the cursor info correctly.

I'm making a game using vb.net and GDI+. I've been encountering frame rate problems and one solution that was suggested to me was to only refresh certain parts of the screen. I was also told one way to make this happen was to use rectangle or region structures and since I already have these as hitboxes it seems like a perfect way to efficiently reduce the drop in frame rate.
The only problem is that I have no idea how this would work and so far my google searches have been fruitless. Yet again I turn to this very helpful forum, can anyone help me? By the way I've set doublebuffered to true on my form to get rid of the annoying flicker.
Questions. How do I update or refresh only certain parts of the screen?
I'm using a timer set to tick every millisecond to run everything and it refreshes the screen every 2 milliseconds simply using me.invalidate; each time it ticks things move a little bit and stuff happens that triggers other events etc. The problem is that when the framerate supposedly "drops" things start to change. "Bullets" and projectiles appear to travel many times faster and much less smoothly than they do when there a less objects moving on the screen, it's almost as if the timer runs faster... What's the reason for this? Is there a way I can change this? I remember hearing about a "stopwatch" or something that someone used in their game that was more consistent or something.
Also I'm aware that vb.net with GDI+ isn't exactly the best language to make a video game in but it's for a school project and I have no choice in the matter.
I might sound somewhat 'newbish', this is my first post on VB. I was wondering if anyone knew how to convert screen coordinates so it works on other screens as well, I made 2 programs, one to get 'my' MOUSE coordinates and the other to click where I want it to click.

I have an image resembling a chessboard inside a picturebox displayed on the screen at runtime. I am using Visual Basic in Visual Studio 2008. I need to determine when a user clicks on a particular part of the image. I am able to do this without a problem when debugging on my computer, where I can experiment with trial-and-error clicking to get the screen coordinates of the portion of the image of interest. Everything changes, however, when the program is run on a screen with a different resolution and coordinates.
I can easily get the coordinates for the picturebox that contains the image using PointToScreen. However, there seems to be no such property for the image within the picturebox, which is what I need.
Here's the code thus far, excuse the other bits in between, these are for getting the foreground form title, form coordinates etc, i now need the cursor coorindates where ever the mouse cursor is to:
Option Explicit On
Imports System.Text
Imports System.Runtime.InteropServices
[Code]....
When I get try and get the x and y coorindates only the x is appearing i think, this gives me a very long number, the y is set to 0. Not sure if I need to take this x number and split it to get my x and y or whether there is logic error in my code
I am working on a project that involves the editing of html of pages on the fly. I have put a webbrowser on the form, and I am able to retrieve the element under my mouse by using: wBrowser.Document.GetElementFromPoint(e.ClientMousePosition) in the Document.MouseClick event.However, I want the experience to be more intuitive, by placing a semi-transparent blue rectangle over whichever HtmlElement the mouse is currently hovering over. I created a borderless form with 20% opacity for this, which works great, except that I cannot for the life of me figure out how to calculate the screen coordinates of the element under my mouse. Here is what I have so far, but while the size is adjusted correctly, the location of the rectangle is just stuck at (0, 0) relative to my form. Highly annoying:

Since the map image is bigger than my screen resolution 1280 x 1024, a horizontal scroll bar is shown. I use Location x and y to place icons, but the problem is:placing an icon at location (0, 0) when the horizontal scroll bar is at left-most position is different from when the horizontal scroll bar is at right-most position...If I move scroll bar to x-axis(right) 10 thenplacing an icon at (0, 0), should be (0, 0) but it is placed at (10, 0).n this case, is there any different approach?

View 7 RepliesHow do i find the cursor coordinates on the screen in VB 2005 code?
"label1.Text = e.Location.X" Only gives you the coordinates in the program window itself, i want it to be displayed in a label/textbox in relation to the whole screen.
is there a way of getting the screen coordinates of individual cells on an open Excel sheet, what I want to ultimately do is pass in a cell range say, "A5" into a function and watch the mouse cursor move slowly to that cell. I know this might seem a weird request. I already have a mouse move function but that accepts the x/y coords in pixel terms where excel using .TOP and .LEFT give an entirely different format?

View 1 RepliesI'm just wondering if it's possible to add the mouse when capturing the screen or monitor in vb.net?
because I'm doing a project that would record the screen and I'm actually successfull doing that by capturing the screen and include it in a timer, but my only problem is the mouse or the cursor isn't showing.
below is my sample code.
Dim ScreenSize As Size = New Size(TotalScreenWitdh, MonitorHeightArray(0))
Dim BMP As New Bitmap(TotalScreenWitdh, MonitorHeightArray(0))

A simple example is: lets say that im trying to make a program that allows you to move the mouse only with the arrows (left/right/up/down) how can i change the position of the mouse on the screen programmatically? If i wanted when you press a button the mouse to change position to X=0,Y=0 of the hole screen/desktop not the window of the form how can i do it? [Code]
View 5 RepliesNormally the event: PanelTransparentMarquee_MouseUp is only raised when the mouse is within the PanelTransparentMarquee panel. I'd like it raised where ever the mouse is on the screen.So in the load event for the usercontraol containing
PanelTransparentMarquee panel I inserted
PanelTransparentMarquee.Capture =
True
But I still only get the PanelTransparentMarquee_MouseUp event when the mouse is within the PanelTransparentMarquee panel.
I thought of something quite cool i would like to try. Would it be possible to revert the mouse and the screen, so when you mouse your mouse up, the arrow stays still but the desktop moves towards it.
