Iterate through the drivers and find and connect to the mouse driver.Your First Hello-Driver App – a Suggestion It’s up to you whether to use the reset function, but it isn’t critical for the mouse driver. Instead, you can send a report with CommandCode = 1, buttons = 0, X and Y = the current desktop mouse coordinates to prevent that jumping cursor.
#Find mouse coordinates windows 10 driver
Internally, the driver will release the buttons and set X = 0 and Y = 0, but that will cause the cursor to noticeably jump. The X and Z values are ignored, so Z and Y to any value you like. To reset the driver, send the report with a CommandCode = 1. Physically press and release the button on a real physical mouse.Send a Reset command to the mouse driver.There are three ways to unstuck a button. It is possible that you may have forgotten, or due to your app crashing, that a button remains pressed. This is a Delphi Word type, which is two bytes.Īs an example, normally a right-mouse-click is 00000 010 and then wait x ms then 00000 000. Y: The mouse absolute Y position from 0 to 32767.This is a Delphi Word type, which is two bytes. X: The mouse absolute X position from 0 to 32767.That is the time the button remains pressed. 00000 010 and then wait x ms and then 00000 000 = to right-click and then release the button.00000 101 = only left and middle buttons pressed.00000 110 = only right and middle buttons pressed.00000 100 = only middle button pressed.We’re not sure how these are sent exactly. Usually those mice will require some additional software/driver from the mouse manufacturer to recognize those buttons. The hid spec supports only three buttons, but obviously most mice have more than that. Releasing a button is done by clearing the bit to zero and sending the report to the driver again. This is basically or’ing the rightmost three bits of the byte to indicate button state. buttons: Left, middle and right mouse buttons are encoded in this byte.CommandCode: This is 1 if resetting the driver, 2 if sending data.ReportID: is always 1, whether sending data or resetting the driver.} HIDMINI_CONTROL_INFO, * PHIDMINI_CONTROL_INFO This corresponds to the following c struct (this is the actual receiving input report struct from the driver source): PTSetFeatureMouseAbs = ^TSetFeatureMouseAbs This is just the terminology left over from Delphi’s JCL and JVCL libraries.: In our Delphi source we call this a Feature, but really it is a standard HID Input Report. Here’s the mouse driver report Delphi data format. Mouse driver reports are based sdk/delphi/common/hut1_12v2.pdf Delphi Then send a packed record as a ‘Feature Report’ to the driver. Sending Data to the Driverįirst, iterate through all drivers until you find ‘Tetherscript Virtual Mouse Abs’ and connect to that driver. If you have multiple monitors, you’ll see the mouse is positioned at the nearest logical location to the coordinates sent. To really get a good understanding of this logic, drag the Mouse Sender utility over to each monitor and try sending (1000, 1000). If you send a coordinate that is not in the light blue area in the diagram above, Windows will send the cursor to the nearest visible location. Send the mouse to the gap at (1000,1000) and where does it go? The answer is ‘nearby’. Note there are ‘gaps’ in the desktop due to varying monitor sizes. So absolute mouse positioning requires a real guarantee of anticipated monitor configurations.Ī Windows desktop with three monitors. This means that sending the mouse to an absolute position of (1000, 1000) on one system will not go the the same place on another system with differently configured monitor(s). The desktop ‘surface’ is defined by your monitor layout as shown below (from Windows 10). Using absolute desktop means that the coordinates are dependent on the number of monitors. Since the driver uses absolute coordinates, you’ll need to use the desktop mouse coordinate system. Be sure to press the ‘Connect to Mouse Driver’ before sending coordinates and button states to the driver. The mouse cursor will respond as if a real physical mouse had been moved and its buttons pressed. Use the SDK Mouse Driver Sender to send absolute coordinates and mouse button states to the mouse driver. Press and/or release the left, middle and right buttons.Note that this is desktop coordinates, not monitor coordinates. Position the cursor with absolute desktop coordinates.The mouse driver abs (absolute) allows you to:
