How to find where is the seconde screen in on a dual monitor systemHello,
I have a dot net application which must use dual screen of windows xp. I use .net 1.1 (and it must be 1.1). Now I can recognize for example from a point that I am not on the PrimeryScreen. Ok. But to make coordinate calculation I must know where is the second screen on the left on the right, below or above. I see no method or property in the Screen Class to determine this. Thank you for any help. Rolf Welskes can u use working area and bounds property of screen

If you open the display control panel applet and adjust the second monitor's position by using arrow keys, you will notice it's moving rounding the primary monitor. Depends on how to define "left" or "right", you need to calculate that accordingly. One thing to note is that the primary screen always originates from (0,0), if the second screen is at the left side of the primary, the X coordinate will be negative. You could easily simulate the display applet's screen position by using the Screen object's Bounds property. Let me know if you need further information regarding this. Thanks.

Hello,
thank you for the answer. With the control panel is clear for me. But this is not the problem. The software product can run on one computer, where the seconde screen is on the left, on another computer, where it is on the bottom, etc. So I must have clear informatiions where it is. The methode to take the coordinates I have tested. BUT: Think at the following: A user has a primary screen with 1000x1000 pixel. A secondary screen with 2000x2000 pixel If i have now the coordindates (1500, 1500) and I know I am on the second screen. But where is it on the right or on the bottom? On the right is possible because of x=1500 because I am outside of the primary screen. Also that y = 1500 is not a problem because I have 2000x2000 So the monitor is on the right. OR: It can also be on the bottom: Because: y = 1500 I am on the bottom because y= 1500 means I am outside the primary screen. x = 1500 is possible, because the monitor has 2000x2000 pixels. So I have (1500,1500) as coordinate, know I am on the second monitor, but I am not able to see where on the right or on the bottom. Is it possible to see clear, on which monitor I am? Thank you for any help.

First we need to know what is called "Virtual Screen": The bounding rectangle of all the monitors is the virtual screen. The desktop covers the virtual screen instead of a single monitor. See following for more info, there's a picture illustrates a possible arrangement of three monitors. #The Virtual Screen http://windowssdk.msdn.microsoft.com/en-us/library/ms534613.aspx The primary monitor contains the origin (0,0). This is for compatibility with existing applications that expect a monitor with an origin. However, the primary monitor does not have to be in the upper left of the virtual screen. When you use WinForm's Location to read the coordinate of the left-top point of your window, it sometimes can be negative (relative to the primary monitor's position). From your example of 1000x1000, 2000x2000 monitors and location (1500,1500), I understand your concern: you will know that the location is not on the primary monitor (using Screen.FromControl(this) to get the screen, then check the Screen.Primary property). To know if the second screen is on right or bottom of the primary one, you need to check the Screen.Bounds property, if it's on right side, the Left property will be 1000; if it's on the bottom side, the Left property will be 0. Actually it's not difficult to simulate the display control panel applet to draw the rectangles represents the screens positions, you just need to know they're on the same virtual screen, and you can know their positions using their Bounds property. Let me know if you need further information. Regards, Walter Wang (waw***@online.microsoft.com, remove 'online.')
