مرسی . امروز خیلی بهتون زحمت دادم .
این را هم از AboutDelphi پیدا کردم ولی هنوز تستش نکردم .
uses DB, ADODB, Variants, ActiveX,
ComObj, AdoInt, OleDB;
...
procedure ListAvailableSQLServers(Names : TStrings);
var
RSCon: ADORecordsetConstruction;
Rowset: IRowset;
SourcesRowset: ISourcesRowset;
SourcesRecordset: _Recordset;
SourcesName, SourcesType: TField;
function PtCreateADOObject
(const ClassID: TGUID): IUnknown;
var
Status: HResult;
FPUControlWord: Word;
begin
asm
FNSTCW FPUControlWord
end;
Status := CoCreateInstance(
CLASS_Recordset,
nil,
CLSCTX_INPROC_SERVER or
CLSCTX_LOCAL_SERVER,
IUnknown,
Result);
asm
FNCLEX
FLDCW FPUControlWord
end;
OleCheck(Status);
end;
begin
SourcesRecordset :=
PtCreateADOObject(CLASS_Recordset)
as _Recordset;
RSCon :=
SourcesRecordset
as ADORecordsetConstruction;
SourcesRowset :=
CreateComObject(ProgIDToClassID('SQLOLEDB Enumerator'))
as ISourcesRowset;
OleCheck(SourcesRowset.GetSourcesRowset(
nil,
IRowset, 0,
nil,
IUnknown(Rowset)));
RSCon.Rowset := RowSet;
with TADODataSet.Create(nil) do
try
Recordset := SourcesRecordset;
SourcesName := FieldByName('SOURCES_NAME');
SourcesType := FieldByName('SOURCES_TYPE');
Names.BeginUpdate;
try
while not EOF do
begin
if
(SourcesType.AsInteger = DBSOURCETYPE_DATASOURCE)
and (SourcesName.AsString <> '') then
Names.Add(SourcesName.AsString);
Next;
end;
finally
Names.EndUpdate;
end;
finally
Free;
end;
end;
وقتی نوشتمش ، میگذارمش همین جا .
