Examples Delphi

For a little tool, I recently needed to get a list of all aliases which point to a SQL db. (I did not want to see those Paradox files).
I came up with the following procedure, which I call like this:
GetAliases (ComboBox1.Items)

procedure GetAliases (const AList: TStrings);
var
i : Integer;
Desc : DBDesc;
Buff : Array [0..254] Of char;
begin
// list all BDE aliases
Session.GetAliasNames (AList);
for i := AList.Count - 1 downto 0 do
begin
StrPCopy (Buff, AList[i]);
Check (DbiGetDatabaseDesc (Buff, @Desc));
// no Paradox, please
if StrPas (Desc.szDBType) = 'STANDARD' then
AList.Delete (i)
end
end;
