Как узнать версию ADO?[править | править код]
{
With different versions of MDAC available it is sometimes
useful to know that your application won't fail because a user
hasn't got the latest version installed.
The following function returns the ADO version installed,
you need to place ComObj in the uses clause to use this function.
}
function GetADOVersion: Double;
var
ADO: OLEVariant;
begin
try
ADO := CreateOLEObject('adodb.connection');
Result := StrToFloat(ADO.Version);
ADO := Null;
except
Result := 0.0;
end;
end;
// To use this function try something like:
procedure TForm1.Button1Click(Sender: TObject);
const
ADOVersionNeeded = 2.5;
begin
if GetADOVersion then
ShowMessage('Need to install MDAC version 2.7')
else
ShowMessage(Format('ADO Version %n, is OK', [GetADOVersion]));
end;
