早些时候我问我怎样才能set Internet Proxy in Windows connection。
但我的问题是,如果我想设置所有连接,那么必须是列表连接名称列表。我在网上搜索,但我找不到任何答案。

您正在寻找RasEnumEntries
功能。 Delphi没有声明RAS API函数,但是如果你有JVCL则很容易。 TJvRas32
组件具有PhoneBook
TStrings属性,其中填充了可用连接。
以下是D2007测试代码(无错误检查):
const
RAS_MaxEntryName = 256;
RASBASE = 600;
ERROR_BUFFER_TOO_SMALL = RASBASE + 3;
ERROR_INVALID_SIZE = RASBASE + 32;
type
PRasEntryName = ^TRasEntryName;
TRasEntryName = record
dwSize: Longint;
szEntryName: array [0..RAS_MaxEntryName] of Char;
end;
function RasEnumEntriesA(reserved: PChar; lpszPhonebook: PChar;
lpRasEntryName: PRasEntryName; var lpcb: DWORD;
var lpcEntries: DWORD): DWORD; stdcall; external 'RASAPI32.DLL';
procedure GetRasEntries(List: TStrings);
var
RasEntryNames: array of TRasEntryName;
Err, Size, Entries: DWORD;
i: Integer;
begin
List.Clear;
SetLength(RasEntryNames, 1);
Size := SizeOf(TRasEntryName);
RasEntryNames[0].dwSize := Size;
Err := RasEnumEntriesA(nil, nil, @RasEntryNames[0], Size, Entries);
if (Err = ERROR_BUFFER_TOO_SMALL) and (Entries > 0) then begin
Assert(Size = SizeOf(TRasEntryName) * Entries);
SetLength(RasEntryNames, Entries);
Err := RasEnumEntriesA(nil, nil, @RasEntryNames[0], Size, Entries);
if Err = 0 then
for i := 0 to Length(RasEntryNames) do
List.Add(RasEntryNames[i].szEntryName);
end else
List.Add(RasEntryNames[0].szEntryName);
end;
procedure TForm1.Button1Click(Sender: TObject);
begin
GetRasEntries(ListBox1.Items);
end;
