I'm trying to get the absolute position of a control on the screen. I'm using two monitors and the results aren't really that great...
What I'm doing is opening another form to capture an image, then passing this image to the main form and closing the capture form. I then want the main form to appear in the same place the picture was captured. To get a gist of what I'm trying to do as an example, open Snipping Tool on Windows and capture a snip. The window will then appear in the place that the image was taken.
This is the current code I am using to do this:
Location = new Point(Cursor.Position.X - CaptureBox.Width - CapturePanel.Location.X - CaptureBox.Location.X - 8, Cursor.Position.Y - CaptureBox.Height - CapturePanel.Location.Y - CaptureBox.Location.Y - 30);
CapturePanel contains the CaptureBox control which stores the picture. I'm also taking 8 from the X location and 30 from te Y location to compensate for the form's border and title bar, but the only problem with this is that some computers will be using a different window style, and these numbers will change.
If there is a method that can be used to grab the border and title width/height of windows, that would be great.
EDIT
A solution to this would be:
Location = new Point(
Cursor.Position.X -
CaptureBox.Width -
CapturePanel.Location.X -
CaptureBox.Location.X -
SystemInformation.HorizontalResizeBorderThickness,
Cursor.Position.Y -
CaptureBox.Height -
CapturePanel.Location.Y -
CaptureBox.Location.Y -
SystemInformation.CaptionHeight -
SystemInformation.VerticalResizeBorderThickness
);
With help from King King pointing out SystemInformation to me.
C programming language is a machine-independent programming language that is mainly used to create many types of applications and operating systems such as Windows, and other complicated programs such as the Oracle database, Git, Python interpreter, and games and is considered a programming foundation in the process of ...
In the real sense it has no meaning or full form. It was developed by Dennis Ritchie and Ken Thompson at AT&T bell Lab. First, they used to call it as B language then later they made some improvement into it and renamed it as C and its superscript as C++ which was invented by Dr.
What is C? C is a general-purpose programming language created by Dennis Ritchie at the Bell Laboratories in 1972. It is a very popular language, despite being old. C is strongly associated with UNIX, as it was developed to write the UNIX operating system.
C is a general-purpose language that most programmers learn before moving on to more complex languages. From Unix and Windows to Tic Tac Toe and Photoshop, several of the most commonly used applications today have been built on C. It is easy to learn because: A simple syntax with only 32 keywords.
To get the Height
of your Window caption
, you can try this:
int captionHeight = yourForm.PointToScreen(Point.Empty).Y - yourForm.Top;
To get the Width
of the form border, you can try this:
int borderWidth = yourForm.PointToScreen(Point.Empty).X - yourForm.Left;
Also you may want to look at the default caption height by SystemInformation.CaptionHeight
.
If you want to get the location of the CaptureBox
in screen coordinates, you can use the PointToScreen
method:
Point loc = CaptureBox.PointToScreen(Point.Empty);
