How to implement code for multiple buttons using c++ in Silverlight for Windows Embedded
- by Abhi
Dear all
I have referred the following link:
Silverlight for Windows Embedded
By referring this link i created a demo application which consist of two buttons created using Microsoft expression blend 2 tools. And then written a code referring the above site. Now my button names are "Browser Button" and "Media Button". On click of any one of the button i should able to launch the respective application. I was able to do for "Browser Button" but not for "Media Button" and if i do for "Media Button" then i am not able to do for "Browser Button".. I mean to say that how should i create event handler for both the buttons.
This is the code in c++ which i should modify
class BtnEventHandler
{
public:
HRESULT OnClick(IXRDependencyObject* source,XRMouseButtonEventArgs* args)
{
RETAILMSG(1,(L"Browser event"));
Execute(L"\\Windows\\iesample.exe",L"");
return S_OK;
}
};
// entry point for the application.
INT WINAPI WinMain(HINSTANCE hInstance,HINSTANCE hPrevInstance,
LPWSTR lpCmdLine,int nCmdShow)
{
PrintMessage();
int exitCode = -1;
HRESULT hr = S_OK;
if (!XamlRuntimeInitialize())
return -1;
HRESULT retcode;
IXRApplicationPtr app;
if (FAILED(retcode=GetXRApplicationInstance(&app)))
return -1;
if (FAILED(retcode=app->AddResourceModule(hInstance)))
return -1;
XRWindowCreateParams wp;
ZeroMemory(&wp, sizeof(XRWindowCreateParams));
wp.Style = WS_OVERLAPPED;
wp.pTitle = L"Bounce Test";
wp.Left = 0;
wp.Top = 0;
XRXamlSource xamlsrc;
xamlsrc.SetResource(hInstance,TEXT("XAML"),MAKEINTRESOURCE(IDR_XAML1));
IXRVisualHostPtr vhost;
if (FAILED(retcode=app->CreateHostFromXaml(&xamlsrc, &wp, &vhost)))
return -1;
IXRFrameworkElementPtr root;
if (FAILED(retcode=vhost->GetRootElement(&root)))
return -1;
IXRButtonBasePtr btn;
if (FAILED(retcode=root->FindName(TEXT("BrowserButton"), &btn)))
return -1;
IXRDelegate<XRMouseButtonEventArgs>* clickdelegate;
BtnEventHandler handler;
if(FAILED(retcode=CreateDelegate
(&handler,&BtnEventHandler::OnClick,&clickdelegate)))
return -1;
if (FAILED(retcode=btn->AddClickEventHandler(clickdelegate)))
return -1;
UINT exitcode;
if (FAILED(retcode=vhost->StartDialog(&exitcode)))
return -1;
return exitCode;
}
I have to add event handler for both the button so that on emulator whenever i click on any one of the button i should be able to launch the respective applications.
Thanks in advance
