ProgramParameter(), max length

Post by horst »

When a command parameter has the length of #MAX_PATH (i.e. 259 bytes plus zero-byte) and is enclosed in quote marks, it will be mutilated. Up to 257 bytes is ok.

Maybe the PB internal buffer that receives the command parameter is not large enough to hold the extra quote marks ???

It should still be possible to use parameters longer than MAX_PATH.

That's a different request.
I just want to use a path parameter with a length up to MAX_PATH (not including the quote marks).

I just tried, but can't see the limit. Can anyone else confirm ?

Code: Select all

openconsole()
a$ = programparameter()
printn(a$)
input()
and paste this as program parameter:

Code: Select all

";11111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111aaaaa"

Confirmed under Vista SP1.
The test works with your 329-char long argument...
No limit.

BTW:

Code: Select all

Debug #MAX_PATH
returns 260 !

I am sorry, I just tested again, and found it is a limitation of the Windows shortcut: The Target cannot be longer than #max_path, including the program path and all parameters. This also applies, when you drag&drop a long file name on a shortcut.

PB seems to handle it correctly.
Sorry
Horst.
