Hi,

I have a problem in File() function.


In the server there is a folder D:\CRMS. And the CRMS folder is
shared.

There is a folder REPORTS in D:\CRMS. ie. D:\CRMS\REPORTS

Server's IP is 192.168.1.100


From the client machine i am trying to check the existance of these
folders.

If (! File("\\192.168.1.100\CRMS","D"))  This retuens .F.
	....Create the folder
EndIf

But

If (! File("\\192.168.1.100\CRMS\REPORTS","D"))  This retuens .T.
	....Create the folder
EndIf

Why ?


When Right Click the Folder and Looking the Property from the Client
Machine, it shows as follows

While checking the Properties of CRMS folder, Type : File Folder
But in the Properties of CRMS\REPORTS, the Type : Share


Regards
Kiron

Hi.
Good day.
Did you try the function FExists() or Directory()?

Kiron,

The File() function should be used only for data or index files that are 
within the Xbase++ default path. For anything else, especially with a fully 
qualified or relative path, I would recommend using the FExists() function.

In either case, there is a workaround, which often works with File() and 
FExists(), which is to add "\*" to the directory name, as in:

File("\\192.168.1.100\CRMS\*", "D")
or
FExists("\\192.168.1.100\CRMS\*", "D")

But, to check for the existence of a directory, especially on a different 
computer, the following function works much better, and doesn't need the 
trailing backslash (or asterisk):

Function Dir_Exists(cDirName)
LOCAL nRet := Get_File_Attributes(ConvToAnsiCp(cDirName))
return (iif(nRet == -1, .f., nRet[5]))

Function Get_File_Attributes(cFileName)
return (DllCall('Kernel32.dll', DLL_STDCALL, 'GetFileAttributesA', ; 
        @cFileName))

Hope that helps,

Andreas

In case you don't use only OEM character sets in your programs, use this 
instead:

Function Dir_Exists(cDirName)
LOCAL nRet := 0
   if Set(_SET_CHARSET) == CHARSET_OEM
      cDirName := ConvToAnsiCP(cDirName)
   endif
   nRet := Get_File_Attributes(cDirName)
return (iif(nRet == -1, .f., nRet[5]))
