Adds a string value to the collection. Please note that this has only an effect in the databound mode if it is called from one of the events AutoDefineNewPage or AutoDefineNewLine.

The API function LlDefineVariableExtHandle is represented by the AddFromHandle method. Here, you can pass a handle in the form of an IntPtr. It is also possible to determine the description of the desired data type. Generally, it is the LlFieldType.Drawing_hBitmap.

Remark: This method should be used only in special situations, such as connecting with Win32 API, if, for example, a component with unmanaged code delivers such a handle. In other cases, you can directly enter the respective Bitmap. The basic abstract class Image also supports a static method FromHBitmap, with the help of which an instance of the Bitmap class can be indicated on the basis of a handle.
