dart - Couldn't find `document._registerDartTypeUpgrader` -

-

My previously executed application now fails to run with the following stacktrace

Exception: Unsupported operation: 'Document._registerDartTypeUpgrader' could not be found, please make sure that 'packages / web_components / interop_support.html' are loaded and available before calling this function. (Package: web_components / interop.dart: 24)

What exactly does it mean?

I have only one problem but only on my Windows machine with this exact same code on the MacBook works fine.

Update:

I compared my Windows machine with the versions of MacBook. They are both:

  • DartSDK 1.7.2_r41096
  • Chromium 37.0.2062.120 (292122)
  • Packages folder symbols point to the exact same version folder

    • Update:

    This is working after changing any "version" for any version and "Pub Upgrade" to the packagepec. The package that was checked in the lock was upgraded. If you rely on any of these, then you can help if you upgrade them:

    • Args
    • Barback
    • code_transformers
    • String_Stress
    • string_scanner
    • Paper_Elements
    • Smoking Sources_maps
    • String_Tas < / Li>

    Especially I doubt the old version of Core_Allements and Paper_Elements to cause this problem, but I do not republish it Is In.

मेरे पास एक टेबल है PersonalInfo जैसे कॉलम जैसे आईडी, नाम, पता । मान लें कि मेरा डेटा निम्न है 1 जॉन यूएस 2 मार्क यूके 3 जॉन यूके 4 डेविड यूएस अब जब मैं नया रिकार्ड निम्न सम्मिलित करता हूं 5 जॉन चीन मैं पिछले रिकार्ड को उसी नाम के रूप में अद्यतन करना चाहता हूँ जैसा कि उदाहरण के लिए नया है जैसा कि यहां दिखाया गया है 3 जॉन यूके को 3 जॉन चीन पर अपडेट कर दिया जाएगा। जब मैं 5 वीं रिकॉर्ड को सम्मिलित करता है तो तालिका 1 जॉन यूएस 2 मार्क यूके 3 जॉन चीन 4 डेविड यूएस 5 जॉन चीन मुझे किस SQL ​​क्वेरी का उपयोग करना चाहिए? आईडी मान लेना ऑटो-वर्धित है, यह उस नाम और पता संयोजन के लिए सबसे अधिक मूल्य होगा। सेट पता personalinfo अद्यतन = 'अमेरिका' कहां आईडी = (चयन मैक्स (आईडी) personalinfo से जहां नाम = 'जॉन' और पता = 'ब्रिटेन')

c# - XML serialize base class without knowing derived class -

-
I know that a XmlSerializer throws an exception if the type passed does not match the type Since then the serializer was created My question is: Is it possible to serial the base type without knowing the derivative type? Consider the following scenario: The following classes are in a top-level domain and there is no dependency : Public Class Serializer {Private Static String Serialize (base basedata) {var serializer = New XML serializer (typefile); Var sb = new stringbilder (); (Var author = XmlWriter.Create (sb)) using {serializer.Serialize (author, bassadata); } Return sb.ToString (); } Private static string Deserialize (...) {...}} Public class base {public string name {get; Set; }} The following derivative classes have additional dependencies on things like UI components, structure, etc. (and more on this later): [Export (Typ (IMyComponent)] Public category was created: Base, IMyComponent, INotifyPropertyChanged {public new string name {get {return base.Name; ...
