ExportObjectPropertyAsBlob method (WinStudio scripts)
Applies To
IWSIDOCollection interface
Definition
Retrieves a binary large object (BLOB), such as a graphic image, from an object in a specified row of a collection and writes it to a file.
Syntax
object.ExportObjectPropertyAsBlob( string1, integer, string2 )
| Part | Description |
| object | Required. An expression that evaluates to the name of an IDO collection object. |
| string1 | Required. The name of a binary property in the collection. |
| integer | Required.
Indicates the row in which the specified object exists.
The row number is zero-based. So, for example, if you want to export the BLOB data from the third row, you must use 2 for this integer |
| string2 | Required. The
name of the file to which the BLOB is to be written.
This string must include a path. The path can be relative to the directory containing WinStudio.exe. |
Remarks
The difference between this method and the ExportCurrentObjectPropertyAsBlob method is that this method acts on an object in a specified (usually other) row, and ExportCurrentObjectPropertyAsBlob references the currently active object.
This method does not create directories.
