In an ASP.NET application, is there a way to get the nlog output to go in a buffer in memory?
I'd like to make a circular buffer that would display the log's content on a web page.
What about writing to the memory target?
Then you could read them as follow:
var target = LogManager.Configuration.FindTargetByName<MemoryTarget>("target1");
var logs = target.Logs;
You can specify custom targets with NLog: https://github.com/nlog/NLog/wiki/Targets
It does not look like one exists that does exactly what you need, but you can write your own!
https://github.com/NLog/NLog/wiki/Extending-NLog
Why don't you read tail n-lines from the actual log file and display it? Or send to a database and display the table? Seems that this will added more overhead and memory constants to the ASP.Net site.

Why is this code added to MetadataTypesHandler.ProcessRequest() in ORMLite for ServiceStack?
httpRes.ContentType = "application/x-ssz-metatypes";
var encJson = CryptUtils.Encrypt(EndpointHostConfig.PublicKey, json, RsaKeyLengths.Bit2048);
httpRes.Write(encJson);
Looks like it's signing the page but the content type is non-standard.
That code lives in ServiceStack project itself, it doesn't have nothing to do with OrmLite. That code is essentially the beginning part of this future feature to provide enough metadata suitable for being able to code-gen DTOs locally as a substitute for sharing dlls. Because it involves code-gen from a remote source it's encrypted to give us better security/control on how and what gets code-gen'ed.
Recently I have started to work with SSRS and found ReportingCloud. It says
ReportingCloud provides an open source quality implementation
as an extension of the RDL specification
I haven't found any tutorial/documentation on how to use it in sourceforge or via google search.
Can anyone give an walk-through/example on How to use ReportingCloud?
There is one partial example available at http://sourceforge.net/projects/reportingcloud/forums/forum/1116661/topic/4571059.
The example takes an existing RDL file, parses and executes it and then places the HTML output into an asp.net Literal Control for display in the browser.
That code snippet is repeated here:
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load("C:\MyFolder\MyReport.rdl");
RDLParser rdlp = new RDLParser(xmlDoc.OuterXml);
rdlp.Parse();
MemoryStreamGen ms = new MemoryStreamGen();
ProcessReport pr = new ProcessReport(rdlp.Report, ms);
pr.Run(null, OutputPresentationType.ASPHTML);
// Dump memory stream (HTML Text) to an out-of-box ASPX Literal control
this.LiteralReportHtml.Text = ms.GetText();
To do this you'll need a reference to ReportingCloud.Engine.
I'm not sure exactly what your bigger goals are but I'd like to draw your attention to another open source project on GitHub called My-FyiReporting https://github.com/majorsilence/My-FyiReporting
Just like ReportingCloud, My-FyiReporting is a fork of FyiReporting (which has gone dormant).
The big difference as far as you are concerned is that My-FyiReporting has ASP.NET samples and an ASP.NET user control link. This might be the fast way to get to what you need.
File ORIGINALPROJECT.TXT from ReportingCloud says:
The ReportingCloud is a fork from the original project fyiReporting
4.1 (http://www.fyireporting.com).
File readme.md from My-FyiReporting says:
My-FyiReporting is a fork of fyiReporting. I cannot stress this
enough. This is a FORK. The main purpose is to make sure that I have a
copy of fyiReporting since that project seems to be dead.
I created simple HttpModule, all what I need is just get is valid Sitecore.Context inside but during processing I see that my Sitecore.Context is some kind of default.
I can get Sitecore user that log in to Sitecore, etc.
How to fix it ?
I assume you have a Sitecore Context, but it is null or set to the wrong site or language.
You can change the context like this:
// switch to the preferred site
Sitecore.Context.SetActiveSite("yourSiteName");
// set the preferred database
Sitecore.Context.Database = Sitecore.Configuration.Factory.GetDatabase("master");
// set the preferred language
Language language = Sitecore.Globalization.Language.Parse("en");
Sitecore.Context.SetLanguage = (language, false);
You probably also want to switch back to the original settings after your processing is done. So it is wise to "save" the original settings in a variable so you can change them back afterwards
Take a look at John West's posts on Sitecore pipelines for some background on how the context is being established.

The following blog post on creating and running custom pipelines should give you an idea how to implement your own pipeline.

When we publish some page/dynamic component from tridion is it possible to add some external multimedia file/content(ex:jpg image) in to current executing/rendering package at publish time.So that final transportation package has this binary file present along with original published content?
Is this achivable using customization of tridion renderer/resolver?If yes please provide some inputs.
*Note:*The binary content that needs to be pushed in to package at publish time is not present as multimedia component in tridion, it is located at other file location outside tridion CMS.Instead we have some stub multimedia component being used inside published component/page which has some dummy image. we plan to replace the stub image with original image at publish(rendering/resolving) time.
Since we have huge bulk of binary content stored in DAM tool we dont want that data to be recreated as multimedia component in tridion, insted we want to use that data by querying DAM tool and attach it in to tridion package with some logical referencesplanning to maintain one to one mapping between stub multimedia comp tcmid to original content in some mapping DB for reference).
Please let us know if any solution is there to attach external binary content to package at publish time.
The best - and easiest way - is to use the mechanism provided by Tridion out-of-the-box for this. Create a new multimedia component, select "External" in the resource type drop-down, and type the URL to the object. As long as you can address it with a URL, it will work exactly as you want (item will be added to package and sent to delivery server).
If this is not good enough for you, then yes, you can add it to the package yourself. I've done this in the past with code somewhat like this:
FileInfo file = // Weird logic to get a FileInfo object from external system
Item item = package.GetItem("My original Item");
item.SetAsStream(file.OpenRead());
This replaced the content of my original component with the actual file I wanted. This will work for you IF the original component is also a multimedia component. If it's not, just create a new item with your own name, etc. If possible, do use the out-of-the-box process instead.
PS: FileInfo Class.
As Nuno suggested the best way is to use multimedia component with 'External' resource type. You may not need to create these manually, you can automate using core services or API programs.
Another way I used before to create zip file at run time and add same to package with following code. Hope it may help.
using (MemoryStream ms = new MemoryStream())
{
zip.Save(ms);
downloadAllInOneURL = String.Format("ZipAsset{0}.zip", uniqueZipID);
downloadAllInOneURL = m_Engine.PublishingContext.RenderedItem.AddBinary(ms, downloadAllInOneURL, "", "application/zip").Url;
downloadAllInOneSize = getSize(ms.Length);
}
i have site where i need to develop site search functionality. the data may reside in database table or may in aspx page as static word. i search google and found that lucene.net may be appropriate for the site search functionality. but i never use lucene.net so i dont know how to create lucene.net index file. i want to develop 2 utility in my site like
1) one for create & update index file reading data from database table & physical aspx file.
2) utility which search multiple single or multiple keyword against index file.
i found a bit of code snippet which i just do not understand
string indexFileLocation = #"C:\Index";
string stopWordsLocation = #"C:\Stopwords.txt";
var directory = FSDirectory.Open(new DirectoryInfo(indexFileLocation));
Analyzer analyzer = new StandardAnalyzer(
Lucene.Net.Util.Version.LUCENE_29, new FileInfo(stopWordsLocation));
what is Lucene.Net.Util.Version.LUCENE_29 what is stopWordsLocation
how data need to store in Stopwords.txt
but have no concept to develop the above 2 utility. so please guide me how search my DB and as well as aspx files with lucene.net....i will be glad if some one discuss here with bit of sample code. thanks
Lucene.Net.Util.Version.LUCENE_29 just indicates the Lucene version your are using, you should always use the most up to date in new code. It is there for backward compatibility in case you upgrade your Lucene with a version that changes the StandardAnalyzer, but you dont want to re-index all your data.
The stopWordsLocation is the location of a file with your stop words, words you dont want to index.
IE: it, he, she, the, or, and etc...
Its a regular text file, each line should contain 1 stop word, and separate each line with a linebreak.
