PCDGetDoc
PCDGetDoc
This object is used to manage the retrieval of a set of physical files that
comprise the components of one version of a document. You use this
object just as you would the
PCDSearch object. Use
PCDGetDoc. AddSearchCriteria to specify the criteria that identify
which document and version you want. Normally, this would mean
specifying criteria like
"%DOCUMENT_NUMBER" "79",
"%VERSION_ID" "3" . The provided criteria must resolve to exactly
one version of one document.
Syntax
PCDGetDoc. methodOrProperty
Returns
PCDGetDoc returns data stored in the COMPONENTS table, including
the document number, version ID, size of the file, and the name of the
file.
Usage
The following steps show the general usage sequence for the
PCDGetDoc object:
1 Specify the library where the document is stored.
2 Provide a DST.
3 Set search criteria that will precisely identify the item you wish to
retrieve.
4 Call PCDGetDoc. Execute method to retrieve the document.
5 Iterate through them using PCDGetDoc. NextRow or call
PCDGetDoc. SetRow to get to a specific item.
6 Call PCDGetDoc. GetPropertyValue to retrieve the file content by
referencing the "%CONTENT" token. This will return a pointer to a
Dispatch interface (a PCDGetStream object) that you can then
use to read the physical file.
