value = %U_WININFO(info[, arg, ...])
or
xcall U_WININFO(info[, arg, ...])
Return value
value
On Windows, a value that is specific to the info flag. On Unix, always returns false. On OpenVMS, always returns true. (^VAL)
Arguments
info
The information to return: (n)
Return the current pixel coordinates for the mouse pointer.
Return the instance handle for the Synergy runtime.
Return the ASCII character that corresponds to a virtual key code.
arg
(optional) Up to two arguments if required for info.
Discussion
%U_WININFO returns Windows-specific information. See the individual subfunctions for details.
If a value other than those listed above is passed for info, a fatal error will occur.

value = %U_WININFO(D_CURSORPOS, x_coordinate, y_coordinate)
or
xcall U_WININFO(D_CURSORPOS, x_coordinate, y_coordinate)
Return value
value
On Windows, true. (^VAL)
Arguments
x_coordinate
The returned x-axis pixel coordinate for the mouse cursor. (n)
y_coordinate
The returned y-axis pixel coordinate for the mouse cursor. (n)
Discussion
The D_CURSORPOS subfunction of %U_WININFO returns the x-axis and y-axis pixel coordinates for the current location of the mouse cursor. Note that these coordinates are relative to the screen, not a window.
Examples
The following example returns in xpos and ypos (both i4) the current pixel coordinates of the mouse cursor relative to the screen.
success = %u_wininfo(D_CURSORPOS, xpos, ypos)
value = %U_WININFO(D_HINSTANCE)
Return value
value
On Windows, the instance handle (D_ADDR) for the Synergy runtime (dbr). (^VAL)
Discussion
The D_HINSTANCE subfunction of %U_WININFO returns the instance handle for the Synergy runtime (dbr). This could be passed, for example, to a DLL routine to create a window. (The instance handle is one of the required arguments to CreateWindow and CreateWindowEx.)
Examples
The following example returns in hinstance the instance handle of the Synergy runtime (.dbr).
hinstance = %u_wininfo(D_HINSTANCE)
value = %U_WININFO(D_VKTOASCII, vk_code[, key_state])
Return value
value
On Windows, the ASCII character that corresponds to vk_code if one exists; otherwise returns 0. (^VAL)
Arguments
vk_code
The virtual key code (numeric value) of any alphanumeric character or any function key as defined in tools.def (D_VKINSERT, D_VK1, and so forth). (n)
key_state
(optional) The key state flags as defined in tools.def: D_KEY_SHIFT, D_KEY_CONTROL, D_KEY_ALT, or any combination of these combined using .BOR. or the vertical bar (|) operator. (n)
Discussion
The D_VKTOASCII subfunction of %U_WININFO returns the ASCII character that corresponds to vk_code or vk_code plus key_state. If this doesn’t result in an ASCII value, D_VKTOASCII returns zero. Note that the numeric values of most printable characters correspond to the ASCII values of the characters. The exceptions are a-z, which use their upper-case values (65-90).
Examples
The following example returns in ascii (i4) the value that corresponds to the letter “a” (lower-case).
ascii = %U_WININFO(D_VKTOASCII, %decml('A'))
The following example returns the value that corresponds to the letter “D” (upper-case).
ascii = %U_WININFO(D_VKTOASCII, %decml('D'), D_KEY_SHIFT)
The next example returns the value that corresponds to the F6 key with the Alt and Ctrl keys.
ascii = %U_WININFO(D_VKTOASCII, D_VKF6, D_KEY_ALT .bor. D_KEY_CONTROL)
