Já tentei de varias maneiras para mostrar o relatorio quando se dá o duplo click no file da report guardada,agora tentei esta procedure no preview e não dá ...quer dizer a report é mostrada na perfeicão muda as paginas tudo correcto apenas quando executa retorna sempre um erro '''Access violation at address 0045D643 in module Gestor.exe read of adress 00000000.

Aqui a procedure....

procedure TfrmPreview.Resgata;
begin
    QRPreview.QRPrinter.Load(ParamStr(1));
   Caption := 'A gerar relatório, por favôr aguarde...';
      if QRPreview.QRPrinter.Title = '' then
          QRPreview.QRPrinter.Title := (ParamStr(1));
            if QRPreview.QRPrinter.PageCount = 1 then
          Self.Caption := QRPreview.QRPrinter.Title + ' - ' + IntToStr(QRPreview.QRPrinter.PageCount) + ' pagina'
        else
          Self.Caption := QRPreview.QRPrinter.Title + ' - ' + IntToStr(QRPreview.QRPrinter.PageCount) + ' paginas';

        bPleaseInit := True;
  Init;
end;
Esta roda em primeiro lugar Main Form. 
procedure TVisualizar.QuickRep1Preview(Sender: TObject);
begin
  Application.CreateForm(TfrmPreview, frmPreview);
  with frmPreview do
  begin
        if ParamCount > 0 then
   if FileExists(ParamStr(1)) then
   begin
pQuickReport:= QuickRep1;
QRPreview.QRPrinter := TQRPrinter(Sender);
Resgata;
show;
  end  else
Caption := 'A gerar relatório, por favôr aguarde...';
pQuickReport:= QuickRep1;
QRPreview.QRPrinter := TQRPrinter(Sender);
Show;
 end;
   end;
end.
Aqui o code completo se executar o executavel ele roda na perfeição mas quando dou duplo click no report guardado...funciona mas dando o erro já descrito em cima. Main form.

Não consigo que funcione logo abrindo o report guardado sem dar erro, já tentei o Debuguer mas tb não encontro o erro...quando dou duplo click na report guardada vejo pelo gestor de tarefas do win que a memória fica em carga e depois de fazer ok na mensagem do erro ela liberta ...mas porquê e onde???

agradecido.

Abraço

Isso é erro de violação de endereço de memória.... durante a execução uma de suas rotinas, ele está tentando atribuir um valor a um endereço de memória ocupado por outro valor.

verifique as rotinas de operação interna ... use o debug do delphi para achar a rotina com o problema

abraço

Está bom mas o problema é quando quero carregar o report salvo...usando '' QRPreview.QRPrinter.Load(ParamStr(1));''

procedure TfrmPreview.Resgata;
begin
    QRPreview.QRPrinter.Load(ParamStr(1));
   Caption := 'A gerar relatório, por favôr aguarde...';
      if QRPreview.QRPrinter.Title = '' then
          QRPreview.QRPrinter.Title := (ParamStr(1));
            if QRPreview.QRPrinter.PageCount = 1 then
          Self.Caption := QRPreview.QRPrinter.Title + ' - ' + IntToStr(QRPreview.QRPrinter.PageCount) + ' pagina'
        else
          Self.Caption := QRPreview.QRPrinter.Title + ' - ' + IntToStr(QRPreview.QRPrinter.PageCount) + ' paginas';

        bPleaseInit := True;
  Init;

Retorna sempre o erro quando vou ao ficheiro guardado e dou um duplo click nele ele abre o preview mostra a report mas retona erro.

Abraço amigo Jhonas.

Perceba, que o procedimento abaixo, faz a mesma coisa que o seu procedimento (procedure TfrmPreview.Resgata)

e não ocorre nenhum erro ... com a diferença que não é preciso usar o TRegistry;

OBS: pelo fato de voce estar usando o TRegistry pode ser isso a causa do erro

Porque voce não substitui essa parte do código para ser se funciona no seu código ( ou use todo o código que te passei ... está funcionando perfeitamente )

procedure TfrmPreview.LoadClick(Sender: TObject);
begin
with TOpenDialog.Create(Application) do
try
Filter := 'QuickReport files (*.qrp)|*.qrp';
if Execute then
if FileExists(FileName) then
begin
QRPreview.QRPrinter.Load(Filename);
QRPreview.PageNumber := 1;
QRPreview.PreviewImage.PageNumber := 1;
if QRPreview.QRPrinter.Title = '' then
QRPreview.QRPrinter.Title := Filename;
if QRPreview.QRPrinter.PageCount = 1 then
Self.Caption := QRPreview.QRPrinter.Title + ' - ' + IntToStr(QRPreview.QRPrinter.PageCount) + rspagina
else
Self.Caption := QRPreview.QRPrinter.Title + ' - ' + IntToStr(QRPreview.QRPrinter.PageCount) + rspaginas;
bPleaseInit := True;
Init;
end
else
ShowMessage(rsImposibleLoadArchivo+ FileName);
finally
free;
end;
end;

Jhonas usando o botão pra carregar esta bom.

rocedure TfrmPreview.LoadClick(Sender: TObject);
begin
with TOpenDialog.Create(Application) do
try

mas eu queria que ao dar um duplo em qualquer report ela carregasse logo no meu Preview.!!! e é ai que dá o erro ela carrega logo sem ter que ir no Opendialog se eu tirar a parte do meu codigo ela funciona bem carrega a report em branco e não a que eu queria com os dados depois se ir pelo botão ela corre normal.

Não sei se eu me estou explicando mal ...você esta entendendo?

Abraço.

usando o TOpenDialog1, ele já faz isso ao voce selecionar o QRP

mas se voce esta querendo dar um click duplo num arquivo QRP sem ser pelo delphi, voce deve associar o arquivo QRP ao seu programa .exe, como é feito pelo windows

Meu Computador > Ferramentas > Opções de Pasta > Tipos de arquivo

É exactanmente isso que o programa faz com aquele code do Registro a extensão .QRP está registada no Windows sem ter que recorrer ao tipo de arquivo e com o meu code com o click duplo no arquivo ele abre o EXE e o arquivo QRP,logo mostrando os dados as paginas tudo certinho só que quando mostra a 1ª página dá aquela mensagem de erro sempre '''Access violation at address 0045D643 in module GestorV.exe read of adress 00000000.

Mas funciona,não fica bloqueado passa as paginas ,imprime etc... mesmo depois se quizer abrir outro pelo OpenDialog tudo bem funciona perfeitamente.

Amigo Jhonas tem jeito de eu mandar pra você o fonte completo.

Abraço.

Fazendo alguns testes com o seu codigo, entendi exatamente o que voce esta querendo

o uso do registry do windows é para associar o seu exe explicitamente com a extensão QRP

executando pelo delphi não ocorre o problema de violação de endereço, porem executando por fora o erro ocorre ( violação de endereço de memoria )

vou mesclar algumas rotinas do seu código com o meu código ... em alguns relatorios ocorre o erro de (metafile is not valid)

isso porque no relatorio tem figuras .... entretanto o codigo que te passei não abre o seu relatorio por estar vinculado ao registro do windows

como já te envie o codigo, voce tambem pode tentar modifica-lo ... vou fazer algumas alterações e depois te informo

abraço
