constants.Standard Element Identifier Strings

The Standard Element Identifier Strings are used to find a VCDPropertyElement of a VCDPropertyItem.

After a VCDPropertyItem object has been retrieved with one of the Standard Property Item Identifier Strings, the property elements of the property item can be retrieved.

The strings are passed to the VCDPropertyElement.FindInterface method. The element type is used to retrieve a sub property of a camera property. For example the exposure camera property can have a value and an auto element. The value element is used to retrieve and set an value (e.g. 114). The auto element is used to enable or disable automation for exposure. An interface to an element is retrieved by adding a string from the Standard Interface Identifier Strings to the Standard Element Identifier String.

The Standard Element Identifier Strings are declared in the module VCDPropertyID.bas. This module is located in the samples\vb6\Common directory of the IC Imaging Control installation directory. To use the strings, the module file VCDPropertyID.bas must be added to the project.

The Basic Use of VCD Properties article in the Programmer's Guide shows how to use the element identifier strings.
