Description
Procedure Open opens a ASCII text file for reading.
Remember to use Close when you are finished reading or writing to a file.
If the filename includes a fully qualified path, the path has to use the appropriate notation for the local operating system:
Macintosh HD:Applications:VectorWorks:Plug-Ins:Data:Notes.txt
C:Program FilesVectorWorksPlug-Ins\Data\Notes.txt
If the filename includes a path relative to the location of the VectorWorks executable, the subfolder delimiters have to be backslashes:
Plug-Ins\Data\Notes.txt
If the filename does not include a path, the file is assumed to exist in the same folder as the VectorWorks executable.
PROCEDURE Open(
fileName :STRING);
def vs.Open(fileName):
return None
Parameters
fileName STRING Name of file to open.
Remarks
Absolute paths versus relative paths:
Accepts platform specific absolute paths, or windows delimited relative paths:
Accepts platform specific absolute paths only:
Returns platform specific absolute paths (user interactive):
Returns platform specific absolute paths (not user interactive):
Example
VectorScript
PROCEDURE Example; VAR fileName :STRING; BEGIN UseDefaultFileErrorHandling(FALSE); fileName := 'Plug-InsCommonDataCallout Prefs.txt'; Open(fileName); AlrtDialog(Concat(GetLastFileErr)); Close(fileName); END; RUN(Example);
