Syntax

'Declaration
Public MustOverride Property ScreenMode As Integer

public abstract int ScreenMode { get; set; }

public:
virtual property int ScreenMode {
    int get () abstract;
    void set (int value) abstract;
}

/** @property */
public abstract int get_ScreenMode ()

/** @property */
public abstract void set_ScreenMode (int value)

public abstract function get ScreenMode () : int

public abstract function set ScreenMode (value : int)

Remarks

If the CapScreenMode property is set to false, ScreenMode is always set to 0. If CapScreenMode is set to true, then ScreenMode can be set to index the values that are contained in the ScreenModeList property. For example:

0 = Default value;

1 = First setting in ScreenModeList;

2 = Second setting in ScreenModeList

Notice that ScreenMode can only be updated when the device is opened and claimed, but not enabled.

Changing ScreenMode also changes the DeviceColumns and DeviceRows properties to the new screen size. Also, for some devices, the MaximumX and MaximumY properties may be changed because of the columns and rows or because of the columns or rows requiring a different number of physical pixels.

ScreenMode is typically initialized to 0 (zero).

Accessing ScreenMode may cause a PosControlException to be thrown with the following ErrorCode.
