Declaration

Delphi

function GetDriverLong(Key: Cardinal): Cardinal;

C/C++

SOPAD_API DWORD SOPAD_GetDriverLong(DWORD dwKey);

ActiveX

HRESULT GetDriverLong([in] long Key, [out, retval] long* Value);

Description

This function returns numerical values.

Arguments

Key

Numerical value, must be equal to one of possible values from the table (see below).

Value

Numerical value which corresponds to the Key.

Possible combinations of key and value

Possible combinations of key and value are listed int the table.

KeyValue
0Driver options 1
1Driver options 2
5Time in milliseconds after which OnSignFinished or OnSignFinishedEx is fired
6Maximum number of tries that FastGetDeviceSettings procedure performs
10Value of parameter passed to OnBigButtonEx handler
11Value of parameter passed to OnSmallButtonEx handler
12Value of parameter passed to OnSignFinishedEx handler
14Minimum possible value of sensor coordinate X (MinX)
15Minimum possible value of sensor coordinate Y (MinY)
16Maximum possible value of sensor coordinate X (MaxX)
17Maximum possible value of sensor coordinate Y (MaxY)
18Sensor resolution by horizontal axis (HorizDPI)
19Sensor resolution by vertical axis (VertDPI)
20Logical width of device's LCD
21Logical height of device's LCD
23

Get saved Rotation setting

0: 0 degrees (normal orientation)

1: 180 degrees (switched orientation)

2: 90 degrees (portrait mode, only Gen13ff)

3: 270 degrees (portrait mode in left handed mode, only Gen13)

25

Queries device, returns display orientation in degrees, only possible values are 0 and 180. Portrait mode is not distingushable.

use GetDriverLong(23) instead.

260: Driver obtains TabeltPC rotation angle from hardware
non-zero: Driver overrides TabletPC rotation angle
27Value of overridden TabletPC rotation angle (in combination with key=26)
28Window handle (HWND) of the window which is disabled when device configuration dialog is shown (in combination with key=29)
290: device configuration dialog doesn't affect other windows
non-zero: when device configuration dialog is shown, window which handle was passed with key=28 is disabled 
30

returns device status;   determine if  signature pad is locked. 

0 : unlocked

1 : locked

31Color of signature line (B-G-R)
32

0: signature image transmission is not finished

NOT IMPLEMENTED

33Number of points in smoothed bitmap data or 0 if signature is not smoothed
34VersionMS
35VersionLS
36Address of OnDeviceButton handler
37Value of parameter passed to OnDeviceButton or OnDeviceButtonCallback handler
39

Size of signature image

High WORD: Width
Low WORD: Height

40Handle of background bitmap
41Queries device, returns free memory size (RAM)

0: pad wasn't opened
1: pad was opened 

45Address of OnDeviceButtonCallback handler
46Returns width of smoothed bitmap or 0 if signature is not smoothed
47

Returns height of smoothed bitmap of 0 if signature is not smoothed

48
