Why need UWP extention

Universal Windows Platform (UWP). It has delicate UI by XAML. But it can not support a lot of WIN32 function. That is why we need UWP extention to unlimited it ability.

Project describe

• Paltform: visual studio 2019
• Function describe: UWP through Windows Desktop Extensions for the UWP tool side loading console.
• Compile sample: UWP can not run at any CPU, and target should set Windows Application Packaging Project.
  

Just sideload other app

• This UWP_extention can side loading winform by using FullTrustProcessLauncher.LaunchFullTrustProcessForCurrentAppAsync().

• Modify WapProj/Package.appxmanifest by adding extensions in Windows Application Packaging Project.

In WapProj/Dependencies

Add UWP extension in UWP/Reference

Add and cover this in UWP/App.xmal.cs

sealedpartialclassApp:Application{publicstaticBackgroundTaskDeferralAppServiceDeferral=null;publicstaticAppServiceConnectionConnection=null;publicstaticboolIsForeground=false;publicstaticeventEventHandler<AppServiceTriggerDetails>AppServiceConnected;publicstaticeventEventHandlerAppServiceDisconnected;privatevoidApp_LeavingBackground(objectsender,LeavingBackgroundEventArgse){IsForeground=true;}privatevoidApp_EnteredBackground(objectsender,EnteredBackgroundEventArgse){IsForeground=false;}/// <summary>/// Initializes the singleton application object.

....

• launch app and re-launch when disconnection Add and cover in UWP/MainPage.xmal.cs

publicMainPage(){this.InitializeComponent();// ApplicationView.PreferredLaunchViewSize = new Size(200, 200);// ApplicationView.PreferredLaunchWindowingMode = ApplicationViewWindowingMode.PreferredLaunchViewSize;}protectedasyncoverridevoidOnNavigatedTo(NavigationEventArgse){base.OnNavigatedTo(e);if(ApiInformation.IsApiContractPresent("Windows.ApplicationModel.FullTrustAppContract",1,0)){//for connect or disconnect event//App.AppServiceConnected += MainPage_AppServiceConnected;//App.AppServiceDisconnected += MainPage_AppServiceDisconnected;//for sideload appawaitFullTrustProcessLauncher.LaunchFullTrustProcessForCurrentAppAsync();}}/// <summary>/// When the desktop process is disconnected, reconnect if needed/// </summary>privateasyncvoidMainPage_AppServiceDisconnected(objectsender,EventArgse){awaitDispatcher.RunAsync(CoreDispatcherPriority.Normal,()=>{Reconnect();});}/// <summary>/// Ask user if they want to reconnect to the desktop process/// </summary>privateasyncvoidReconnect(){if(App.IsForeground){MessageDialogdlg=newMessageDialog("Connection to desktop process lost.

Sideload app and UWP can change message in two way

Go to BelaunchedApp/reference and add those file

• It can send data and receive data
  Add and cover sildload_app/program

classProgram{staticprivateAppServiceConnectionconnection=null;staticvoidMain(string[]args){InitializeAppServiceConnection();strings_res;Console.WriteLine("[1] send data to UWP");while((s_res=Console.ReadLine())!=""){inti_res=int.Parse(s_res);if(i_res==1){Send2UWP_2("Hi!","UWP");}}}/// <summary>/// Open connection to UWP app service/// </summary>staticprivateasyncvoidInitializeAppServiceConnection(){connection=newAppServiceConnection();connection.AppServiceName="SampleInteropService";connection.PackageFamilyName=Package.Current.Id.FamilyName;connection.RequestReceived+=Connection_RequestReceived;connection.ServiceClosed+=Connection_ServiceClosed;AppServiceConnectionStatusstatus=awaitconnection.OpenAsync();if(status!=AppServiceConnectionStatus.Success){//In console, something wrongConsole.WriteLine(status.ToString());//In app, something went wrong ...//MessageBox.Show(status.ToString());//this.IsEnabled = false;}}/// <summary>/// Handles the event when the desktop process receives a request from the UWP app/// </summary>staticprivateasyncvoidConnection_RequestReceived(AppServiceConnectionsender,AppServiceRequestReceivedEventArgsargs){// retrive the reg key name from the ValueSet in the request/* string key = args.Request.Message["KEY"] as string; if (key == "abcd") { // compose the response as ValueSet ValueSet response = new ValueSet(); response.Add("GOOD", "KEY IS FOUNDED ^^"); // send the response back to the UWP await args.Request.SendResponseAsync(response); } else { ValueSet response = new ValueSet(); response.Add("ERROR", "INVALID REQUEST"); await args.Request.SendResponseAsync(response); } */int?key1=args.Request.Message["KEY1"]asint?;int?key2=args.Request.Message["KEY2"]asint?;if(key1!=null&&key2!=null){intans=(int)key1+(int)key2;// compose the response as ValueSetValueSetresponse=newValueSet();response.Add("KEY3",ans);// send the response back to the UWPawaitargs.Request.SendResponseAsync(response);}}/// <summary>/// Handles the event when the app service connection is closed/// </summary>staticprivatevoidConnection_ServiceClosed(AppServiceConnectionsender,AppServiceClosedEventArgsargs){//In console, connection to the UWP lost, so we shut down the desktop processConsole.WriteLine("UWP lost connection!

Tip

Also can try this if slected multiple keys

in sildload_app/program

/// <summary>/// Handles the event when the desktop process receives a request from the UWP app/// </summary>privateasyncvoidConnection_RequestReceived(AppServiceConnectionsender,AppServiceRequestReceivedEventArgsargs){Console.WriteLine("Connection_RequestReceived");foreach(objectkeyinargs.Request.Message.Keys){if((string)key=="BasicInfo"){Console.WriteLine("BasicInfo");GetInformationgetInformation=newGetInformation();getInformation.InitializeWMIHandler();if(getInformation.InitGlobalVariable()==0)//have errpr{// compose the response as ValueSetValueSetresponse=newValueSet();response.Add("BasicInfo2UWP","Error! Please restart.");// send the response back to the UWPawaitargs.Request.SendResponseAsync(response);}else{stringbasicInfo=getInformation.GetInfomation();// compose the response as ValueSetValueSetresponse=newValueSet();response.Add("BasicInfo2UWP",basicInfo);// send the response back to the UWPawaitargs.Request.SendResponseAsync(response);}}elseif((string)key=="deviceConfig"){DeviceStatedeviceState=newDeviceState();uint?deviceCode;uintstate=deviceState.GetDeviceStatePower();deviceCode=args.Request.Message["deviceConfig"]asuint?;try{foreach(uintdeviceinEnum.GetValues(typeof(DeviceState.DeviceStatePower))){if((deviceCode&device)==device){state=state^(uint)deviceCode;deviceState.SetDeviceStatePower(state);}}}catch(Exceptione){//TODO: not verifyvardialog=newMessageDialog(e.Message);awaitdialog.ShowAsync();}// compose the response as ValueSetValueSetresponse=newValueSet();state=deviceState.GetDeviceStatePower();response.Add("res_deviceConfig",state);// send the response back to the UWPawaitargs.Request.SendResponseAsync(response);}}}

Package to app

• First should generate self-signed certification for UWP and WapProj.
  
  

• Add picture If use default picture may will error
  
  

• Package In WapProj
  
  next
  
  next
  
  x64 Release

• Sign
  Go to C:...\HotTab_Win10\WapProj_HotTab_Win10\bin\x64\Release
  
  
  
  
  
  Add below 3 picture sign
  
  
  

Or, It will show error code 0x800B010A

Other

error code => DEP1000: Cannot copy file
Just close all debug window
