WNetEnumResource and Error 487

Lance,

after I compiled that small example on a W2K system it works.
It does not work on W2K when compiled on Win98.
It does not work on Win98 when compiled on Win98.

The API calls are the same so that's not it. Any other ideas?

Thomas.

Lance,

this is exactly the code I've used and with the WNetEnumResource
function I'm getting this 487 error.
This code is not the only one I tried. I had a snippet from the MSDN CD
with another example and this one is giving me the same error.
Is it possible that the API call is wrong with the parameters?

Regards.
Thomas

Check out Lance's code, but you'll have to customize it because it uses the STDOUT function, so won't work in a Windows program.

To be clear, you probably mean a PB/DLL program, since PB/CC programs are Windows programs.

Oops. Wrong API Check out Lance's code, but you'll have to customize it because it uses the STDOUT function, so won't work in a Windows program.

This works:
1. Open a DOS box, and run eg. "net use x: \\W2K\C$" where W2K is the name of your local box

2. Run this code:

#COMPILE EXE
#DIM ALL
#REGISTER NONE

#INCLUDE "WIN32API.INC"

Function PbMain () AS LONG
Local lResult AS LONG
Local sDrive AS ASCIIZ * 4
Local sPath AS ASCIIZ * 128

sDrive = "X:"

lResult = WNetGetConnection (sDrive,sPath, sizeof(sPath))
Select Case lResult
Case %NO_ERROR
MsgBox "Success! Remote host is " + sPath
Case Else
MsgBox "Error: " + str$(lResult) + ". Check WIN32API.INC and WIN32.HLP for more infos."
End Select


End Function

The following is some PB/CC code that works fine for me (tested with PB/CC 2.0 under Windows 2000)

  LOCAL nSize   AS LONG
  LOCAL ec      AS LONG
  LOCAL x       AS LONG
  LOCAL t       AS STRING
  STATIC s      AS STRING
 
  DIM n(1 TO 256) AS NETRESOURCE
 
  Entries = 256
  nSize   = SIZEOF(nr) * Entries
 
  s = s + "  "
 
  ec = WNetOpenEnum(%RESOURCE_GLOBALNET, %RESOURCETYPE_ANY, %NULL, nr, hEnum)
  ec = WNetEnumResource(hEnum, Entries, n(1), nSize)
 
  FOR x = 1 TO Entries
    t = LEFT$(s & n(x)[email protected] + SPACE$(40), 40) + n(x)[email protected]
    IF LEN(RTRIM$(t)) THEN
      STDOUT t
    END IF
    IF (n(x).dwUsage AND %RESOURCEUSAGE_CONTAINER) THEN
      EnumAll n(x)
    END IF
  NEXT
 
  s = LEFT$(s, LEN(s) - 2)
END SUB

Hi there,
now I'm comming in here with another (I think crazy) problem.
Everytime I call the WNetEnumResource Function I'm getting an
487 error that drives me nuts. Searching the Deja News up and down
but can not get an answer. I found sample codes but they give me
the same error messages and it looks like they work for their authors.
Does anyone have experience or snippets for enumerating network.

BTW I'm using PBDLL 6.0

Any help appreciated
Thomas Noelker
