• Microsoft FoxPro for Macintosh, versions 2.5b, 2.5c

SYMPTOMS

After you have transported an application from FoxPro for Windows or FoxPro for MS-DOS to FoxPro for Macintosh, the icons, file types, and creators appear to be incorrect for all the files in the application.

NOTE: This behavior does not occur under Visual FoxPro for Macintosh.

CAUSE

The creator, type, and subsequent icon are determined by the application that created the file on the Macintosh. When an application is transported, the creator may become Apple File Exchange or another program instead of FoxPro for Macintosh.

However, using the code example below, you can programmatically change the creator and type for an entire folder of files at a time.

RESOLUTION

The following program will change all files with standard FoxPro extensions, within a single folder, to a creator of "FOXX". Files without standard FoxPro extensions will be ignored.

The code example below uses the FxSetType() function in FOXTOOLS.MLB to change the creator and type for the files. The SYS(2027) syntax returns the filenames in Macintosh notation. Both FxFileType() and FxSetType() require the filename to be specified in Macintosh notation.
