Let's say I have to compile two different versions of my .swf for different sites. The difference is in hostnames for the ajax and redirection, several minor tweaks in code and in graphics added to the project in .swc. I can switch different swcs easily, but the code tweaks are hard to manage easily. I've got
CONFIG::site1
{
private var _domainName:String = "site1.com";
}
CONFIG::site2
{
private var _domainName:String = "site2.com";
}
FB brings up an error: 1151: A conflict exists with definition _domainName in namespace internal.
What I need is smthn like this in C:
#ifdef SITE1
char hostname[] = "site1";
#endif
#ifdef SITE2
char hostname[] = "site2";
#endif
Is there any way to use compile directives that way using mxmlc?
P.S. Everything works now
I think this documentation will help you.
In your case it is something like the following:
private var _domainName:String = NAMES::site;
And mxmlc arguments will look like:
-define+=NAMES::site,"'site1.com'"
You could do this :
private var _domainName:String = CONFIG::site1 ? "site1.com" : "site2.com";
If you want to know what's possible with configuration constants have a look at this page :
http://wiki.ecmascript.org/doku.php?id=proposals:program_configuration
So far I've found that the compiler support everything mentioned on this page.
Why code the domains at all?
Not a directive or specifically an answer to your question I'm just saying lol
private var _domainName:String;
var lc:LocalConnection = new Local
this._domainName= lc.domain;

Background
I have a piece of LESS code that needs to be compiled at runtime with Less.js -- it calculates some things via JavaScript -- so I can't use the task runner, etc.
In my index.html, I have:
<head>
...
<link rel="stylesheet/less" href="assets/less/DynamicHeight.less" />
...
<script type="text/javascript" src="lib/less/less.js"></script>
...
</head>
Problem
Less.js appears unable to find the file:
And when I try to access the file directly, I see:
Question
How can I add the configuration that will allow this less file to be downloaded? Am I still able to use web.config files with vNext, or do I need to do something with config.json instead?
Lead 1: Should I use Owin?
Thinking this might be the right path but I'm pretty unfamiliar.
I see a number of tutorials out there, such as K. Scott Allen's, which reference code such as:
public void Configuration(IAppBuilder app)
{
var options = new StaticFileOptions
{
ContentTypeProvider = new FileExtensionContentTypeProvider()
};
((FileExtensionContentTypeProvider)options.ContentTypeProvider).Mappings.Add(
new KeyValuePair<string, string>(".less", "text/css"));
app.UseStaticFiles(options);
}
However, it appears that in its current version, asp.net is looking for a signature of Configure(IApplicationBuilder app) instead.
The IApplicationBuilder class doesn't have a method along the lines of UseStaticFiles -- it only has a signature of IApplicationBuilder Use(Func<RequestDelegate, RequestDelegate> middleware).
I have a feeling that this is likely the right path to solve the issue -- I just can't find out how to propertly configure the IAppliationBuilder to map the MIME extension.
Okay, I believe I figured it out.
Step 1: Add the appropriate library for static files
In ASP.NET vNext, this is Microsoft.Aspnet.StaticFiles.
In your project.json file, add the following under "dependencies":
"Microsoft.AspNet.StaticFiles": "1.0.0-beta2"
This adds the static middleware method that you can use later.
Step 2: Configure the app to use Static Files
Add the using statement at the top:
using Microsoft.AspNet.StaticFiles;
At this point, the app.UseStaticFiles method will be available, so your Configure method can look as follows:
public void Configure(IApplicationBuilder app)
{
var options = new StaticFileOptions
{
ContentTypeProvider = new FileExtensionContentTypeProvider()
};
((FileExtensionContentTypeProvider)options.ContentTypeProvider).Mappings.Add(
new KeyValuePair<string, string>(".less", "text/css"));
app.UseStaticFiles(options);
}
And voila! I get text when browsing to .less files, and no more error is appearing from LessJS.
In .NET Core 1.0.1, SeanKileen answer is still good. The following is a simple code rewrite:
public void Configure(IApplicationBuilder app, ...)
var contentTypeProvider = new FileExtensionContentTypeProvider();
contentTypeProvider.Mappings[".map"] = "application/javascript";
contentTypeProvider.Mappings[".less"] = "text/css";
app.UseStaticFiles(new StaticFileOptions()
{
ContentTypeProvider = contentTypeProvider
});
The above code EXTENDS the default mapping list (see the source), which already has ~370 mappings.
Avoid using the FileExtensionContentTypeProvider constructor overload that takes a dictionary (as suggested by JHo) if you want those 370 default mappings.
SeanKilleen's answer is right on, and still works ASP.NET Core RC1. My only improvement is to write the exact same code using collection initializers to make it cleaner.
app.UseStaticFiles(new StaticFileOptions
{
ContentTypeProvider = new FileExtensionContentTypeProvider(new Dictionary<string, string>
{
{ ".less", "text/css" },
{ ".babylon", "text/json" },
// ....
})
});
I'm trying to get some file information about a file the user select with the FileOpenPicker, but all the information like the path and name are empty. When I try to view the object in a breakpoint I got the following message:
file = 0x03489cd4 <Information not available, no symbols loaded for shell32.dll>
I use the following code for calling the FileOpenPicker and handeling the file
#include "pch.h"
#include "LocalFilePicker.h"
using namespace concurrency;
using namespace Platform;
using namespace Windows::Storage;
using namespace Windows::Storage::Pickers;
const int LocalFilePicker::AUDIO = 0;
const int LocalFilePicker::VIDEO = 1;
const int LocalFilePicker::IMAGES = 2;
LocalFilePicker::LocalFilePicker()
{
_init();
}
void LocalFilePicker::_init()
{
_openPicker = ref new FileOpenPicker();
_openPicker->ViewMode = PickerViewMode::Thumbnail;
}
void LocalFilePicker::askFile(int categorie)
{
switch (categorie)
{
case 0:
break;
case 1:
_openPicker->SuggestedStartLocation = PickerLocationId::VideosLibrary;
_openPicker->FileTypeFilter->Append(".mp4");
break;
case 2:
break;
default:
break;
}
create_task(_openPicker->PickSingleFileAsync()).then([this](StorageFile^ file)
{
if (file)
{
int n = 0;
wchar_t buf[1024];
_snwprintf_s(buf, 1024, _TRUNCATE, L"Test: '%s'\n", file->Path);
OutputDebugString(buf);
}
else
{
OutputDebugString(L"canceled");
}
});
}
Can anybody see whats wrong with the code or some problems with settings for the app why it isn't work as expected.
First an explanation why you are having trouble debugging, this is going to happen a lot more when you write WinRT programs. First, do make sure that you have the correct debugging engine enabled. Tools + Options, Debugging, General. Ensure that the "Use Managed Compatibility Mode" is turned off.
You can now inspect the "file" option, it should resemble this:
Hard to interpret of course. What you are looking at is a proxy. It is a COM term, a wrapper for COM objects that are not thread-safe or live in another process or machine. The proxy implementation lives in shell32.dll, thus the confuzzling diagnostic message. You can't see the actual object at all, accessing its properties requires calling proxy methods. Something that the debugger is not capable of doing, a proxy marshals the call from one thread to another, that other thread is frozen while the debugger break is active.
That makes you pretty blind, in tough cases you may want to write a littler helper code to store the property in a local variable. Like:
auto path = file->Path;
No trouble inspecting or watching that one. You should now have confidence that there's nothing wrong with file and you get a perfectly good path. Note how writing const wchar_t* path = file->Path; gets you a loud complaint from the compiler.
Which helps you find the bug, you can't pass a Platform::String to a printf() style function. Just like you can't with, say, std::wstring. You need to use an accessor function to convert it. Fix:
_snwprintf_s(buf, 1024, _TRUNCATE,
L"Test: '%s'\n",
file->Path->Data());
I'm looking for a free tool or dlls that I can use to write my own code in .NET to process some web requests.
Let's say I have a URL with some query string parameters similar to http://www.example.com?param=1 and when I use it in a browser several redirects occur and eventually HTML is rendered that has a frameset and a frame's inner html contains a table with data that I need. I want to store this data in the external file in a CSV format. Obviously the data is different depending on the querystring parameter param. Let's say I want to run the application and generate 1000 CSV files for param values from 1 to 1000.
I have good knowledge in .NET, javascript, HTML, but the main problem is how to get the final HTML in the server code.
What I tried is I created a new Form Application, added a webbrowser control and used code like this:
private void FormMain_Shown(object sender, EventArgs e)
{
var param = 1; //test
var url = string.Format(Constants.URL_PATTERN, param);
WebBrowserMain.Navigated += WebBrowserMain_Navigated;
WebBrowserMain.Navigate(url);
}
void WebBrowserMain_Navigated(object sender, WebBrowserNavigatedEventArgs e)
{
if (e.Url.OriginalString == Constants.FINAL_URL)
{
var document = WebBrowserMain.Document.Window.Frames[0].Document;
}
}
But unfortunately I receieve unauthorizedaccessexception because probably frame and the document are in different domains. Does anybody has an idea of how to work around this and maybe another brand new approach to implement functionality like this?
Thanks to the Noseratio's comments I managed to do that with the WebBrowser control. Here are some major points that might help others who have similar questions:
1) DocumentCompleted event should be used. For Navigated event body of the document is NULL.
2) Following answer helped a lot: WebBrowserControl: UnauthorizedAccessException when accessing property of a Frame
3) I was not aware about IHTMLWindow2 similar interfaces, for them to work correctly I added references to following COM libs: Microsoft Internet Controls (SHDocVw), Microsoft HTML Object Library (MSHTML).
4) I grabbed the html of the frame with the following code:
void WebBrowserMain_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
if (e.Url.OriginalString == Constants.FINAL_URL)
{
try
{
var doc = (IHTMLDocument2) WebBrowserMain.Document.DomDocument;
var frame = (IHTMLWindow2) doc.frames.item(0);
var document = CrossFrameIE.GetDocumentFromWindow(frame);
var html = document.body.outerHTML;
var dataParser = new DataParser(html);
//my logic here
}
5) For the work with Html, I used the fine HTML Agility Pack that has some pretty good XPath search.
I have a bunch (over 1000) HTML files with just simple text. It's just a combination of text within a <table>. It's an internal batch of documents, not for web production.
The job we have is to convert them into JPEG files using Photoshop and the old copy paste method. It's tedious.
Is there a way you would do this process to make it more efficient/easier/simple?
I thought about trying to convert the HTML into Excel and then mail merging it into Word to print as JGEG. But I can't find (and rightly so) anything to convert HTML to XLSX.
Thoughts? Or is this just a manual job?
Here's a little something I created to convert a single html file to jpeg. It's not pretty (to say the least), but it works fine with a table larger than my screen. Put it inside a windows forms project. You can add more checks and call this program in a loop, or refactor it to work on multiple html files.

You can load all files in one page and use this lib html2canvas to covert.
You can running in the background use nodejs with node-canvas or make it a desk app with node-webkit
In case anyone was looking for answer that works, I ended up using a program called Prince: https://www.princexml.com
It works amazingly, and just have to target the HTML with CSS or JS to make it match your output!
I am trying to render emails in a windows service host.
I use RazorEngine 3 forked by coxp which has support for Razor 2.
https://github.com/coxp/RazorEngine/tree/release-3.0/src
This works fine for a couple of emailtemplates but there is one causing me problems.
#model string
Click here to enter a new password for your account.
This throws a CompilationException: The name 'WriteAttribute' does not exist in the current context. So passing in a string as model and putting it in the href-attribute causes problems.
I can make it work by changing this line by:
#Raw(string.Format("Klik hier.", #Model))
but this makes the template very unreadable and harder to pass along to a marketing department for further styling.
I like to add that referencing the RazorEngine by using a Nuget package is not a solution since it is based on Razor 1 and somewhere along the process the DLL for system.web.razor gets replaced by version 2 which breaks any code using RazorEngine. It seems more interesting to use Razor 2 to benefit from the new features and to be up to date.
Any suggestions on how to fix this would be great. Sharing your experiences is also very welcome.
UPDATE 1
It seems like calling SetTemplateBaseType might help, but this method does not exist anymore, so I wonder how to be able to bind the templatebasetype?
//Missing method in the new RazorEngine build from coxp.
Razor.SetTemplateBaseType(typeof(HtmlTemplateBase<>));
I use Windsor to inject the template service rather than using the Razor object. Here is a simplified part of the code that shows how to set the base template type.
private static ITemplateService CreateTemplateService()
{
var config = new TemplateServiceConfiguration
{
BaseTemplateType = typeof (HtmlTemplateBase<>),
};
return new TemplateService(config);
}
RazorEngine 3.1.0
Little bit modified example based on coxp answer without the injection:
private static bool _razorInitialized;
private static void InitializeRazor()
{
if (_razorInitialized) return;
_razorInitialized = true;
Razor.SetTemplateService(CreateTemplateService());
}
private static ITemplateService CreateTemplateService()
{
var config = new TemplateServiceConfiguration
{
BaseTemplateType = typeof (HtmlTemplateBase<>),
};
return new TemplateService(config);
}
public static string ParseTemplate(string name, object model)
{
InitializeRazor();
var appFileName = "~/EmailTemplates/" + name + ".cshtml";
var template = File.ReadAllText(HttpContext.Current.Server.MapPath(appFileName));
return RazorEngine.Razor.Parse(template, model);
}
