  18. Windows System usage samples • Using path variables: • LOCAL nKey, cSubKey, cValue, lSuccess, cExpandPart, cNonExpandPart • nKey= HKEY_LOCAL_MACHINE • cSubKey= "Software\VfpRegTest" • cValue= "TestREG_EXPAND_SZ" • cExpandPart= "WINDIR" • cNonExpandPart= "\System“ • lSuccess= WriteREG_EXPAND_SZ(nKey, cSubKey, cValue, cExpandPart, cNonExpandPart) • IF (lSuccess) • THEN • =MESSAGEBOX("Value was Written to the Registry.") • ELSE • =MESSAGEBOX("Value was not Written to the Registry.") • ENDIF

  19. Windows System usage samples • HRESULT verification macros (Accessing a known folder): • IShellItem* pItem = nullptr; • HRESULT hr = ::SHCreateItemInKnownFolder( • FOLDERID_Libraries, 0, nullptr, IID_PPV_ARGS(&pItem)); • if (SUCCEEDED(hr)) • { • DWORD dwAttr = 0; • hr = pItem->GetAttributes(SFGAO_FILESYSANCESTOR, &dwAttr); • if (SUCCEEDED(hr)) • { • if (SFGAO_FILESYSANCESTOR == dwAttr) • { • wprintf(L"Item is a file system folder\n"); • } • } • pItem->Release(); • }

  20. Best practice: manifest Your executable Build great desktop apps

  21. Trust info • <?xml version="1.0" encoding="utf-8"?> • … • <trustInfoxmlns="urn:schemas-microsoft-com:asm.v2"> • <security> • <requestedPrivilegesxmlns="urn:schemas-microsoft-com:asm.v3"> • <requestedExecutionLevel level=“AsInvoker" uiAccess="false" /> • </requestedPrivileges> • </security> • </trustInfo>

  22. Compatibility section • Compatibility • <?xml version="1.0" encoding="UTF-8" standalone="yes"?> • <assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0"> • <compatibility xmlns="urn:schemas-microsoft-com:compatibility.v1"> •     <application> •        <supportedOS Id=“{Windows 8…GUID}"/> •        <supportedOS Id=“{Windows 7…GUID}"/> •          <supportedOS Id="{Windows Vista…GUID}"/> •       </application> • </compatibility> • </assembly>

  23. DPI section • <assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0" xmlns:asmv3="urn:schemas-microsoft-com:asm.v3" > • <asmv3:application> <asmv3:windowsSettings xmlns="http://schemas.microsoft.com/SMI/2005/WindowsSettings"> • <dpiAware>true</dpiAware> • </asmv3:windowsSettings> • </asmv3:application> ... </assembly>

  28. Declaring compatibility in the Appx Manifest • As part of app manifest • <Prerequisites> • <OSMinVersion>6.2</OSMinVersion> • <OSMaxVersionTested>6.2</OSMaxVersionTested> • </Prerequisites>

  29. Assess your Metro style app • Ensures consistent, high-quality user experience • Single tool for self-testing and store onboarding • Prepared for a global market • Automated tests for: • App Manifest compliance with store policy • Image sizing and scaling • Use of platform supported APIs • App reliability and security
