Title: Registering a Type Library
Question: How do I register a .tlb file for a COM object from within my application, as opposed to having to use the TRegSvr utility?
Answer:
The following code will register any type library, provided you supply the filename.
uses
ActiveX, SysUtils, COMObj;
procedure TfrmLogin.RegTypeLibrary( Const FileName: String );
var
wFileName: WideString;
DocName: WideString;
TypeLib: ITypeLib;
begin
if not( FileExists( FileName ) ) then
Raise Exception.Create( 'Type library not found' );
wFileName := FileName;
OleCheck( LoadTypeLib( PWideChar( wFileName ), TypeLib ) );
OleCheck( TypeLib.GetDocumentation( -1, nil, nil, nil, @DocName ) );
DocName := ExtractFilePath( DocName );
OleCheck( RegisterTypeLib( TypeLib, PWideChar( wFileName ), PWideChar( DocName ) ) );
end;
