"bpl" load in IntraWeb - delphi

Question

I am setting up a module of "bpl" load in IntraWeb, Delphi2010, and I found the following problem:
I don't get to create an instance the application to not to be this is as an internal form.
.
procedure CargaDoSubModulo;
type
TIWFormClass = class of TIWForm;
var
Integra : IIntegracaoIW;
Formulario : TIWForm;
intClas : Integer;
strForm : String;
begin
strForm := srtPacotes + '_' + Copy ( IntToStr ( Rtn_Alternativa) + 10000 ), 2, 4 );
// Descrição do formulário
strDescricaoTela := Des_Tela;
// Nome da classe do formulário
vrtClasseModulo := 'p_' + strForm + '.dll';
// Nome da rotina interna a ser carregada
strForm := 'iwfrm_' + strForm;
// Nome da classe do formulário
vrtNomeFormulario := 'T' + strForm;
// Verificação se a rotina e compativel com o sistema iwfrm_hrb_0010
intClas := -1;
if WebApplication.FindComponent( strForm ) = nil then
begin
Formulario := TIWFormClass(FindClass( vrtNomeFormulario )).Create(WebApplication);
if not Supports (Formulario, IIntegracaoIW) then
begin
WebApplication.ShowMessage(CargaTexto(msnRotIncompIntgra), smAlert);
Exit;
end;
Integra := Formulario as IIntegracaoIW;
with Integra do
begin
SetServidor( ParServidor1.Servidor ); // 1
SetAreaTrabalho( ParServidor1.AreaTrabalho ); // 2
SetIdUsuario( intUsuario ); // 3
SetNomeUsuario( iwlStUsuario.Caption ); // 11
SetAcesso( intAcesso ); // 4
SetEmpresa( ParServidor1.Empresa ); // 5
SetFilial( ParServidor1.Filial ); // 6
SetIdClasse( intClas ); // 8
SetVersao( strVersaoInterna ); // 10
SetDescricao(Des_Tela ); // 7
SetEnderecoIP( strIdentificacaoPorta ); // 13
SetDataTrabalho( DateToStr(dtDataTrabalho) ); // 14
SetIdentificacaoSistema( iwlIdentificacao.Caption ); // 12
SetModuloCarga(Rtn_Busca ); // 9
end;
end;
TIWAppForm(WebApplication.FindComponent( strForm )).Show;
end;

Answer 1

Your question - or actually the exact problem/error - is a bit unclear to me. Locating a form via FindComponent is a bit uncommon. At least you shouldn't call FindComponent more than nessecary, as it is potentially slow.
If you create a Form with WebApplication being the owner, it will be added to WebApplication.Forms
Web Application.FormCount is the number of forms (UserSession is a form in this context). WebApplication.ActiveForm is the form that is currently shown.
