如何通过PowerBuilder代码访问受密码保护的网络共享文件夹？有没有选择？

我正在使用PowerBuilder 11.5

这是我松了一口气的代码片段。我不确定消息来源，所以我不能给予适当的信任。

FUNCTION long ShellExecuteW &
    (long hwnd, string lpOperation, &
    string lpFile, string lpParameters,  string lpDirectory, &
    integer nShowCmd ) LIBRARY "shell32"

    string ls_Null
long   ll_rc

SetNull(ls_Null)
ll_rc = ShellExecuteW &
( handle( this ), "open", as_path, ls_Null, ls_Null, 1)

RETURN ll_rc


How about run("net use ...")
where net use syntax is :

NET USE [devicename | *] [\\computername\sharename[\volume] [password | *]]
        [/USER:[domainname\]username]
        [[/DELETE] | [/PERSISTENT:{YES | NO}]]

DWORD WNetCancelConnection2(
  _In_  LPCTSTR lpName,  (string)
  _In_  DWORD dwFlags,  (ulong)
  _In_  BOOL fForce
);

DWORD dwResult;
dwResult = WNetCancelConnection2("z:", 
    CONNECT_UPDATE_PROFILE, // remove connection from profile (use 1)
    FALSE);                 // fail if open files or jobs 

DWORD WNetUseConnection(
  _In_     HWND hwndOwner,
  _In_     LPNETRESOURCE lpNetResource,
  _In_     LPCTSTR lpPassword,
  _In_     LPCTSTR lpUserID,
  _In_     DWORD dwFlags,
  _Out_    LPTSTR lpAccessName,
  _Inout_  LPDWORD lpBufferSize,
  _Out_    LPDWORD lpResult
);

Function Declaration:

FUNCTION ulong WNetUseConnectionA (ulong hwndOwner, &
   REF s_netresource lpNetResource, string lpPassword, 
   string lpUsername, ulong dwFlags, REF string lpAccessName, &
   REF ulong lpBufferSize, REF ulong lpResult) library "mpr.dll"
Structure Definition:

$PBExportHeader$s_netresource.srs
global type s_netresource from structure
 unsignedlong  dwScope
 unsignedlong  dwType
 unsignedlong  dwDisplayType
 unsignedlong  dwUsage
 string  lpLocalName
 string  lpRemoteName
 string  lpComment
 string  lpProvider
end type
Mapping Code:

CONSTANT ulong NO_ERROR = 0
CONSTANT ulong CONNECT_REDIRECT = 128
CONSTANT ulong RESOURCETYPE_DISK = 1

s_netresource lstr_netresource

String   ls_null
String   ls_buffer
String   ls_MappedDrive

uLong    ll_bufferlen
uLong    ll_null
uLong    ll_ErrInfo
uLong    ll_success

SetNull(ll_null)
SetNull(ls_null)

ls_buffer = Space(32)
ll_bufferlen = Len(ls_buffer)

lstr_netresource.dwType = RESOURCETYPE_DISK
lstr_netresource.lpLocalName = ls_null
lstr_netresource.lpRemoteName = "UNC resource name here"
lstr_netresource.lpProvider = ls_null

ll_ErrInfo = WNetUseConnectionA(ll_null, lstr_netresource, &
   'password', 'username', &
   CONNECT_REDIRECT, ls_buffer, ll_bufferlen, ll_success)

IF ll_ErrInfo = NO_ERROR THEN
   MessageBox("Drive Mapped", "Drive Letter is " + ls_buffer)
   Return 1
ELSE
   MessageBox("Mapping Falied", "Error is " + String(ll_ErrInfo))
   Return -1
END IF
