[ "C# WebBrowser, injecting JavaScript doesn't update HtmlDocument", "I'm trying to resolve an issue that's disconcerting me. It might be something obvious but I can't really figure out what's wrong.\n\nI have a winform with a WebBrowser which I load this way and it works fine:\n\n WebBrowser.DocumentText = someHtmlCode;\n\n\nIn my winform's webbrowser I can right-click to get the HTML source and check out that the code is the same I set in the DocumentText property... everything's ok at this point.\n\nSo once I get it loaded and working, I inject some JavaScript code into it, something like this:\n\n HtmlElement head = WebBrowser.Document.GetElementsByTagName(\"head\")[0];\n HtmlElement scriptEl = WebBrowser.Document.CreateElement(\"script\");\n IHTMLScriptElement element = (IHTMLScriptElement)scriptEl.DomElement;\n element.text = \"function sayHello() { alert('hello') }\";\n head.AppendChild(scriptEl);\n\n\nSo I'm adding a new JavaScript function named \"sayHello\" that I can call this way, and it's still working properly:\n\n WebBrowser.Document.InvokeScript(\"sayHello\");\n\n\nSo everything's ok at this point, I can run the JavaScript function and getting the alert inside the WebBrowser, but what's disconcerting me is that when I right-click on the WebBrowser to get the source code, I get the same code I set at the beginning. No trace about the JavaScript code added later, although it's there because it's working when I invoke it.\n\nOf course, if I look into the WebBrowser.HtmlDocument, I can't see the JavaScript either, it's the same that I get looking at the source code.\n\nSo my question is: where's the new JavaScript code going and how can I get it back? I need to get the updated HTML code.\n\nThanks!" ]

(One\n exception is if an argument Foo or\n const Foo& has a non-explicit,\n one-argument constructor, in which\n case we need the full definition to\n support automatic type conversion.)\n We can declare static data members of type Foo.

Why is the full definition needed if we want to support automatic type conversion?\n\nMy guess is that compiler needs the full definition of the destination type because of the temporary object that is created in the implicit conversion. Am I guessing correctly? Is there more to it?\n\nEDIT:\n\nAs I see it, the exception in the guideline is addressed to situation like this:\n\nclass A\n{\n public:\n A( int );\n};\n\nclass B\n{\n public:\n B( A const &a );\n};\n\nint main()\n{\n B b(2);\n}\n\n\nHere we have only one user-defined implicit conversion (from int to A), and call to constructor that accepts A const &.

[ "Issues after upgrading Hot Towel NuGet Package", "I recently ran into a problem upgrading a project I created that was based on the Hot Towel SPA Visual Studio Template. I had a \"moment\" and accidentally ran the update-package command in the NuGet Package Manager Console, which triggered an update of ALL my NuGet packages - including the Hot Towel NuGet package. \n\nThis had the effect of upgrading my project to the latest Hot Towel version and re-adding all the sample views, view models, etc... that I previously deleted or renamed from the original starter project that Hot Towel created. The NuGet upgrade also failed to refresh files that had I had changed intentionally (\\scripts\\_references.js, \\App_Start\\BundleConfig.cs) or unintentionally (where VS had normalized tab\\whitespace in some files I had opened in the IDE). \n\nHas anyone else experienced this? \n\nIt seems pretty unlikely you would ever update the Hot Towel NuGet package for any project that takes root and was built off of the template. I could see later in the project lifecycle updating the dependencies like Breeze, Bootstrap, Toastr, etc..., but just not Hot Towel.\n\nIs it best to just unhook NuGet for Hot Towel once you create your project? This would prevent accidental updates of Hot Towel from re-introducing starter code into your project.\n\nDespite this challenge, Hot Towel is proving to be a great starting point for SPAs. I'm really enjoying working with it.\n\nThanks,\nRichard" ]
