Long File name support in Foxprow 2.6a by snix2
Posted: 21 Jan 03

Here's a quick snippet which converts long file name paths to foxpro compatible short file paths. e.g. 'c:\program files' becomes 'c:\progra~1'.

*************************************************
* This function will convert long path names to
* foxpro compatible short path names
* It uses the winapi function 'GetShortPathName'
* And the foxpro FOXTOOLS.FLL library    
*************************************************

set library to sys(2004)+'FOXTOOLS.FLL'

*** Register the windows API function...
GetShort = regfn('GetShortPathName','@C@CI','I')

*** Create a variable for holding the results
Buffer = SPACE(500)

*** Set the longpath variable to be the normal long pathname
*** Example here is c:\program files...
longpath = ALLTRIM(SYS(5)) + '\Program Files'

*** Call the function
Result = callfn(GetShort, @longpath, @buffer, 500)

*** remove the trailing null terminating character (Chr(0))
Buffer = left(buffer, result)

? Buffer

*************************************
** Now the 'buffer' variable contains an
** untrimmed short path name
** The 'Result' variable holds a number.
** This number is the number of characters long
** that the short file name is.
** Usable by foxpro.
*************************************
