本文介绍如何利用AIW框架动态地为应用程序添加功能，通过Contact应用提供的'Assign'AIW服务，实现为现有联系人分配图像或设置铃声的功能。详细展示了从头文件引入到执行命令的代码流程。

Assign Image to contact using AIW service

Overview
Application Interworking (AIW) framework is a mechanism for dynamically adding features and functionality to applications without statically linking to the existing code. Contact application provides ‘Assign’ AIW service through which we can assign image or Ringtone to existing contact.
Here is the code to assign image to contact.

Header file
#include <AiwServiceHandler.h>
#include <aiwgenericparam.h>
class CContactAIWAssign31AppUi : public CAknAppUi
    {
public:

    …

     // From MEikMenuObserver
    void DynInitMenuPaneL(TInt aResourceId,CEikMenuPane* aMenuPane);

    //For Passing parameters
    void AiwParamListLC( CAiwGenericParamList& aParamList ) const;

public:
   CAiwServiceHandler* iServiceHandler;

    };
Source file
void CContactAIWAssign31AppUi::ConstructL()
    {
iServiceHandler = CAiwServiceHandler::NewL();
//Attach menu services
iServiceHandler->AttachMenuL(R_CONTACTAIWASSIGN31_MENU,R_ASSIGN_INTEREST);
}

void CContactAIWAssign31AppUi::HandleCommandL(TInt aCommand)
    {
    switch(aCommand)
        {
        case EEikCmdExit:
        case EAknSoftkeyExit:
            Exit();
            break;
       default:
           CAiwGenericParamList& inList = iServiceHandler->InParamListL();
           AiwParamListLC(inList);
           iServiceHandler->ExecuteMenuCmdL(aCommand,inList,iServiceHandler->OutParamListL(),0,NULL);
            break;
        }
    }

void CContactAIWAssign31AppUi::DynInitMenuPaneL(
    TInt aResourceId, CEikMenuPane* aMenuPane)
    {
    if (iServiceHandler -> IsAiwMenu(aResourceId))
    {
    //Create in param list
CAiwGenericParamList& inList = iServiceHandler->InParamListL();
    AiwParamListLC(inList);
iServiceHandler->InitializeMenuPaneL(*aMenuPane,aResourceId,EAIWMenuPlaceHolder,inList);
    }
    }

void CContactAIWAssign31AppUi::AiwParamListLC(CAiwGenericParamList& aParamList) const
{
     _LIT(KFilename,"C://Sample1.jpg");
      _LIT(KFileMime,"image/jpeg");

      // Append Filepath as parameter
       TAiwVariant varFile(KFilename);
       TAiwGenericParam paramFile( EGenericParamFile, varFile );
       aParamList.AppendL( paramFile );

      //Append Mime type(for Image - image/jpeg)
       TAiwVariant varMime(KFileMime);
       TAiwGenericParam paramMime( EGenericParamMIMEType, varMime );
       aParamList.AppendL( paramMime );

}
