.net - How to get NLog to parse contents of file-contents renderer? -


मेरे पास एक NLog लक्ष्य है: 

  & lt; लक्ष्य नाम = "aspNetAsyncWrapperForMail" xsi: type = "ASPNetBufferingWrapper" & gt; & Lt; लक्ष्य नाम = "मेल" xsi: प्रकार = "मेल" विषय = "त्रुटि: $ {callites: includeSourcePath = False}" smtpServer = "MySMTP" से = "me@test.com" से = "मुझे @ परीक्षण" Com "smtpAuthentication =" None "body =" $ {date} $ {फाइल-सामग्री: $ {baseir} /error.html} "html =" true "/ & gt; & Lt; / लक्ष्य & gt;

Error.html इस तरह दिखता है: 

  & lt; div & gt; & Lt; b & gt; संदेश & lt; / b & gt; = $ {message} & lt; / div & gt;

मैं error.html की सामग्री को पार्स करने के लिए NLog कैसे प्राप्त कर सकता हूं, ताकि $ {message} param को NLog नियमों के साथ प्रदान किया जाए?

मैंने इस पर एक चाकू लिया और इस समाधान के साथ आया:

  • मेरा नया रेंडरर NLog.LayoutRenderers से मिला है। FileContentsLayoutRenderer

  • उसके बाद, ऐपेंड () विधि में, मुझे यह कोड है (जो फ़ाइल कंटेंट्स लयआउट रेंडरर के ऐप () विधि में बहुत ही समान है: 

      lock (यह) {var fileName = FileName.GetFormattedMessage (logEvent); अगर (fileName! = M_LastFileName) {ReadFileContents (fileName);} var लेआउटस्ट्रिंग = नया लेआउट (_fileContents); m_RenderedContent = layoutString.GetFormattedMessage (logEvent); m_LastFileName = fileName; } बिल्डर। ऐपेंड (एम_रेंडर कंटेंट);

इस के साथ सबसे बड़ी समस्या यह है कि जब तक ऐप के ऐपडोमेन रीसायकल न हो जाए, उस फाइल को ऐन स्मृति में और कभी डिस्क से फिर से पढ़ा नहीं। तो परिवर्तन करना शुरू में उत्पादन को प्रभावित नहीं करता है।

मैंने इसे संभालने के लिए कुछ डिबग कोड जोड़ दिया है, लेकिन उत्पादन वातावरण में परिवर्तन को पहचानने के लिए अधिक मजबूत कोड जोड़ने की आवश्यकता है।

c++ - QtQuick: QQmlApplicationEngine failed to load component qrc:/main.qml:23 Invalid attached object assignment -

Looking at my thoughts below, am I barking the wrong tree? Or in the information given below, am I misusing the Qt API to get an error in the title? I'm trying to modify the sample to work with the default coefficic project generated from Qt Creator 3.3.0 (OpenSource). Qt 5.4.0 (GCC 4.6.1, 64bit) Based on. The first thing to look at after the code is that I stand by: The sample uses the main.cpp: qmlRegisterType & lt ; Squircle & gt; ("OpenGLUARMM", 1, 0, "Squircle"); QQuickView view; View.setResizeMode (QQuickView :: SizeRootObjectToView); View.setSource (QUrl ("QRC: ///scenegraph/openglunderqml/main.qml")); View.show (); Some name changes in my name. CPP qmlRegisterType & lt; Menuscreen & gt; ("OpenGLUnderQML", 1, 0, "Main Screen"); QQmlApplicationEngine engine; Engine.load (QUrl (QStringLiteral ("QRC: /main.qml"))); I'm not sure that the difference in using QQmlApplicationEngine...

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
