ReplacePart Method
Replaces the contents of the specified part in the package.
Syntax
int ReplacePart();
Remarks
If the part specified by the PartName property exists, the corresponding physical file will be replaced with the contents of the PartData property. The package file will be modified in place right away.
If the part doesn't exists, it's stored in interleaved format, or PartData is null or empty, an error will be raised.
Error Handling
This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)
