Pergunta

Eu tenho uma biblioteca de classes compilada contendo um controle do usuário e gostaria de adicioná -lo a uma página da web. Estou adicionando uma tag de objeto à página HTML que se parece:

 <OBJECT id="Main" classid="http://localhost/HelloWorld/Hello.World.dll#Hello.World.UserControl"></OBJECT>

No entanto, o controle não está sendo exibido. A DLL chega aos meus arquivos temporários e eu fico em branco na caixa de objeto na página da web. Recebo uma mensagem de erro nos meus arquivos temporários da Internet que se parecem:

? Fusionbinderror! Name = hello.world.dll hello.world.userControl

Não sei mais como depurar isso. Estou me perguntando se é um problema de nomes?

O seguinte erro acabou no log:

Solução

Dentro desse arquivo, há um rastreamento de pilha - se você o postar, eu poderá ajudar.

Além disso, você precisa ter confiança total com o site configurado no seu painel de controle de configuração .NET XX (ou usar o Caspol para defini-lo).

Veja como depurar

  1. Use Fiddler (Google, download e execute).
  2. Recarregue a página
  3. O controle é baixado? Você recebe um HTTP 500-se sim, desligue os "scripts e executáveis" no diretório no IIS --- IIS acha que isso é uma dll isapi e o executará se todos executáveis
  4. Você recebe um vínculo de fusão (você tem) - o que há nele - deve ser um rastreamento de pilha - você jogou? Você pode consertar?
  5. Você tem total confiança configurada com o site?

Outras dicas

Observação: o IE8 desativa os controles do usuário na zona da Internet; portanto, lembre -se disso se você planeja implantar isso em um ambiente de produção.
