What I'm trying to do is to get the X and Y position of mouse but not starting from the screen upper left corner but the stage's upper left corner. Right now all I got is:
mouseCoordsLabel.Text = ("X: " & MousePosition.X - Me.Location.X & " Y: " & MousePosition.Y - Me.Location.Y)
But it gets the upper left corner of form, not stage. Is there any way I could get the width and height of the borders that the form uses?
I was wondering what would be an easy way to get the coordinates within a webbrowser?
View 3 Repliesadd a brush/shape to a picture box. I have a few buttons; one will create a fille rectangle and another one will create a pen shape rectangle on a given point cooridnate. the code goes something like this:
Using abrush As New SolidBrush(ColorDialog1.Color), formGraphics As Graphics = PictureBox1.CreateGraphics()
formGraphics.FillRectangle(abrush, New Rectangle(ToolStripTextBox1.Text, ToolStripTextBox2.Text, ToolStripTextBox3.Text, ToolStripTextBox4.Text))
End Using
this is an example of the code that works perfectly well. but what I want it to do is instead of the user having to input coordinates, I want it so that you click on the button (any of em) and then be able to use the mouseposition.x & y to draw the shape (so if you enter the picture box container and then you click on it it will draw the shape from the point where the mouse cursor is..)
So I have decided to learn more about this Invalidate() thing. I decided to simply draw a rectangle where the mouse clicks in the form, for testing.
Code:
Public Class Form1
Dim p As Point

I found out how to get the emulator working for my kinectmultipoint on 32-bit and 64-bit machines (i still need to confirm 64-bit by tests but 32-bit works). I used the webbrowser controls invokescript property and placed my vbscript code in an html page to tell internet explorer engine to pass script to correct version scripting engine when executing the vbscript.
after using navigate property I use these lines of code:
In form load: 'setup the softehci controller before executing dsf code!
Shell("C:Program Filesdsfsoftehcisoftehcicfg /REMOVE")
Shell("C:Program Filesdsfsoftehcisoftehcicfg /REMOVE")
In button1 click event: Webbrowser1.Navigate("path to html file with vbscript")
Webbrowser1.Invokescript("my vbscript method")
Note: i think this approach only works in local mode not on a web server or such.
So if anyone wants to check up on the project or help me i just need to change the vbscript to add multiple mouse devices and then i portion it up to do these three main functions:1. Add a new mouse device when kinect detects another person walking up to computer.
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.
View 3 RepliesI 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?
Is there any way to invert the screen. For example, making upside down or having mirror effect?
View 1 RepliesI created a function that creates a global temporary table to stage data from a excel sheet I need the table to persist for me to map the columns using a form. The table is still there when the code goes back to the sub that calls the function until I call the form where I do the mapping. I am trying to avoid create/drop table scenario with a perm stage table.How can I get this table to persist until the data gets loaded into the perm table?
View 8 RepliesBTW 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 RepliesCurrently I have the following VB.NET code to make a screenshot of my desktop, but it only takes a picture of the active screen:
Public Function SaveScreen(ByVal theFile As String) As Boolean
Try
SendKeys.Send("%{PRTSC}")[code].....
The following code is how I execute the above function, if it makes any difference, which I don't think it does:
SaveScreen("C:Lexer_tracescreen.png")
Now, I need to be able to take a picture of the entire screen, not just the focused window.
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 :
<div style="margin: 0 auto; width: 500px;"></div>
But this is for web pages using HTML and CSS.
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:

View 2 RepliesI 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?

View 3 RepliesI wanted to make a screen recorder (not screen capture) program, but I am not entirely sure how to get it started. I have seen many videos and things on how to make one, but all of these just take multiple pictures and then don't compile them into a movie file, and I don't want to take many pictures (unless that is the only way possible.) I am using Visual Basic 2010 Express and I have looked at the Windows Media Encoder, but I can't seem to figure out how to use/implement it (yes, I have downloaded and installed it.) Maybe I can use some kind of ActiveX control?

I wrote a quick web screen scraper in VB.Net. I couldn't believe how incredibly easy it was to do! Now I have all of this HTML that I can parse, peruse, and purge. I have access to this one site in particular. It requires a login and password, both of which I have.
Here is the problem: I want to log into this site programatically, that is, pass the userid and password from my program. Without this, I cannot get to the screens that appear after a successful login is completed.
I am thinking that the way to get around this limitation is to somehow TRAP what the site passes from my browser session to its server. Then I can simulate that action from within my program.Before anyone raises an eyebrow... no, I am not trying to hack anything. I just want to process the screens that come up after I log in!

Some programs display a window, like some antivirus programs, at the windows welcome screen. This is before anybody has logged in.I want to do the same thing. I am creating a security program that can be used for maybe a library to monitor the computer and/or block webpages (That's another thread!).Anyhow, how would I be able to have my program run before anybody logs on. Would it have to be a Windows Service? How could I get it to be running in safe mode, too.
