Hi I'm trying to set up log4net without using XML configuration:
public void InitLogger()
{
//Create exception log file if it haven't been created
var exceptionLogFile = new FileInfo(System.Configuration.ConfigurationManager.AppSettings["ExceptionLogFilePath"]);
if (!exceptionLogFile.Exists)
{
exceptionLogFile.Create();
}
//configure log4net
var smtpAppender = new SmtpAppender
{
SmtpHost = "",
Authentication = SmtpAppender.SmtpAuthentication.None,
BufferSize = 512,
From = "",
To = "",
Layout = new PatternLayout(""),
Lossy = true,
Evaluator = new LevelEvaluator(Level.Error)
};
var fileAppender = new FileAppender
{
File = System.Configuration.ConfigurationManager.AppSettings["ExceptionLogFilePath"],
AppendToFile = true,
Layout = new PatternLayout(""),
LockingModel = new FileAppender.MinimalLock() //use the minimal locking model that allows multiple processes to write to the same file
};
BasicConfigurator.Configure(smtpAppender);
}
My problem is that I want to use two appenders (smtp and file). Using
BasicConfigurator.Configure(smtpAppender);
I can set the initial one but I also need to set the file appender. Do you know a why to do it?
Thanks for your time :)
In this scenario, you want to get the instance of the logger then add your appenders. After that, just configure the repository. I.e. ,
In VB:
Public Class Test
Private Shared ReadOnly _logger As log4net.ILog = log4net.LogManager.GetLogger(System.Reflection.MethodInfo.GetCurrentMethod().DeclaringType)
Sub InitLogger()
Dim logger = CType(_logger.Logger, log4net.Repository.Hierarchy.Logger)
Dim fileAppender = New log4net.Appender.FileAppender() With { _
.File = "", _
.AppendToFile = True, _
.Layout = New log4net.Layout.PatternLayout(""), _
.LockingModel = New log4net.Appender.FileAppender.MinimalLock() _
}
logger.AddAppender(fileAppender)
Dim repository As log4net.Repository.ILoggerRepository = log4net.LogManager.GetRepository()
log4net.Config.BasicConfigurator.Configure(repository)
End Sub
End Class
In C#:
public class Test
{
private static readonly log4net.ILog _logger = log4net.LogManager.GetLogger(System.Reflection.MethodInfo.GetCurrentMethod().DeclaringType);
public void InitLogger()
{
var logger = (log4net.Repository.Hierarchy.Logger)_logger.Logger;
var fileAppender = new log4net.Appender.FileAppender {
File = "",
AppendToFile = true,
Layout = new log4net.Layout.PatternLayout(""),
LockingModel = new log4net.Appender.FileAppender.MinimalLock()
};
logger.AddAppender(fileAppender);
log4net.Repository.ILoggerRepository repository = log4net.LogManager.GetRepository();
log4net.Config.BasicConfigurator.Configure(repository);
}
}

I'm developing a project that will require me to include credentials for things like an SMTP server. I'd like to store this information along with the complete details of the endpoint in an embedded JSON file, but I would like to have that information encrypted and then let my application decrypt it when it needs to establish a connection and log in. The JSON structure looks something like this:
{
"Endpoints" : [
{
"Endpoint" : {
"Host": "smtp.mydomain.tld",
"Port": 587,
"Username": "user#mydomain.tld",
"Password": "mYp#s$w0?d"
}
}
]
}
While what I'd really like to have actually stored in the file would look something like this:
{
"Endpoints" : [
{
"Endpoint" : "<BASE64_ENCODED_STRING>"
}
]
}
Using Newtonsoft's Json.NET, I've built the class object/properties to desriealize this structure:
<JsonProperty("Endpoints")>
Public Property Endpoints As List(Of EndpointContainer) = Nothing
Public Class EndpointContainer
<EditorBrowsable(EditorBrowsableState.Never)> <DebuggerBrowsable(DebuggerBrowsableState.Never)>
Private Const EncryptedPrefix As String = "myappcipher:"
<EditorBrowsable(EditorBrowsableState.Never)> <DebuggerBrowsable(DebuggerBrowsableState.Never)>
<JsonProperty("Endpoint")> <JsonConverter(GetType(EndpointProtector))>
Public Property Endpoint As Endpoint = Nothing
End Class
And I've built the inherited JsonConverter class ("EndpointProtector") like this:
Public Class EndpointProtector
Inherits JsonConverter
Public Sub New()
Using SHAEncryption = New SHA256Managed()
_EncryptionKey = SHAEncryption.ComputeHash(Encoding.UTF8.GetBytes(TestEncryptionKey))
End Using
End Sub
Public Overrides Sub WriteJson(writer As JsonWriter, value As Object, serializer As JsonSerializer)
Dim clearText As String = JsonConvert.SerializeObject(value)
If clearText Is Nothing Then
Throw New ArgumentNullException(NameOf(clearText))
End If
writer.WriteValue(EncryptEndpoint(clearText))
End Sub
Public Overrides Function ReadJson(reader As JsonReader, objectType As Type, existingValue As Object, serializer As JsonSerializer) As Object
Dim DecryptString As String = TryCast(reader.Value, String)
If String.IsNullOrEmpty(DecryptString) Then
Return reader.Value
ElseIf Not DecryptString.StartsWith(EncryptedPrefix, StringComparison.OrdinalIgnoreCase) Then
Return DecryptString
Else
Return DecryptEndpoint(DecryptString)
End If
End Function
Public Overrides Function CanConvert(objectType As Type) As Boolean
Throw New NotImplementedException()
End Function
End Class
Currently I have the JSON file itself with the full object definition (as in the first code block). When my application reads that JSON, it correctly moves to the overridden ReadJson() method I have, but the reader.Value is null (Nothing), so it never actually gets to the DecryptEndpoint() method. Of course, that means there's nothing to encrypt, so the application won't even step into the WriteJson() method.
I've tried a couple of variations, including making the Endpoint property into a private variable with a generic Object type, and then having a separate public property with the <JsonIgnore> decoration to "read" from that, but nothing seems to get me where I need to be. I'm sure I'm overlooking something here, but I can't seem to figure out why it's not getting anything at all.
I looked at a few other SO questions like Encrypt and JSON Serialize an object, but I've still not yet been able to figure out quite where I've gone wrong here.
NOTE: I intentionally didn't include the code for the EncryptEndpoint() or DecryptEndpoint() methods here simply because the code is never making it that far in the process. If you feel it's needed to fully answer the question, please let me know.

returning a workbook via an httpresponse in a get call, the method used for an older version of ClosedXML, now returns an empty workbook - workbook tabs are created and correctly named, but are empty.
Sample code - trimmed down for basic response
public HttpResponseMessage Get([FromUri]ControlReportsView model)
{
string client = "EU";
ClosedXML.Excel.XLWorkbook workbook = CreateWorkbook(model, client);
MemoryStream stream = new MemoryStream();
workbook.SaveAs(stream);
stream.Position = 0;
var response = Request.CreateResponse(HttpStatusCode.OK);
response.Content = new StreamContent(stream);
response.Content.Headers.ContentDisposition = new ContentDispositionHeaderValue("attachment");
response.Content.Headers.ContentType = new MediaTypeHeaderValue("application/octet-stream");
response.Content.Headers.ContentDisposition.FileName = string.Format("{0}_{1:yyyyMMdd hhmmtt} to {2:yyyyMMdd hhmmtt}.xlsx", model.Type.ToString(), model.StartDate, model.EndDate);
response.Headers.CacheControl = new CacheControlHeaderValue()
{
Private = true,
MaxAge = TimeSpan.FromSeconds(300)
};
return response;
}
private static ClosedXML.Excel.XLWorkbook CreateWorkbook(ControlReportsView model, string client)
{
using (var workbook = new ClosedXML.Excel.XLWorkbook())
{
CreateTestTab(model, client, workbook);
return workbook;
}
}
private static void CreateTestTab(ControlReportsView model, string client, XLWorkbook workbook)
{
var worksheet = workbook.Worksheets.Add("Sample Sheet");
var firstRow = worksheet.FirstRow();
firstRow.Cell("A").Value = "Hello World!";
}
public class ControlReportsView
{
public enum ControlReportType
{
[Description("R")]
Inbound,
[Description("S")]
Outbound
}
public ControlReportType Type { get; set; }
public DateTime StartDate { get; set; }
public DateTime EndDate { get; set; }
}
I suspect there's a more elegant tool to do the response now, of which I'm unaware.
I have another file I'm returning successfully via another method, but I'm loath to make this big a change to the set up of the current file:
var stream = new MemoryStream();
workbook.SaveAs(stream);
byte[] fileArray = stream.ToArray();
//build file name
DashObject FarmInfo = (DashObject)MySession.Info;
string ProjName = FarmInfo.ProjectName;
string datemade = DateTime.Now.ToString("yyyyMMdd-HHmmss");
string docName = String.Format("Subscribers_{0}_{1}.xlsx", ProjName, datemade);
Response.ContentType = "application/octet-stream";
string attachVal = "attachment; filename=" + docName;
Response.AppendHeader("Content-Disposition", attachVal);
Response.BinaryWrite(fileArray);
Response.End();
Wow, that was weird.
The data was never making it into the worksheets, even tho they were getting created.
Removing the Using clause somehow sorted it:
private static ClosedXML.Excel.XLWorkbook CreateWorkbook(ControlReportsView model, string client)
{
ClosedXML.Excel.XLWorkbook workbook = new ClosedXML.Excel.XLWorkbook();
CreateTestTab(model, client, workbook);
return workbook;
}
I suspect somehow the worksheet in the using didn't pass back and forth properly for some reason - can anyone confirm?
When I use Aspose.Word to export a .docx with multiple images into html, I can save those images into MemoryStream, for example, I can use IImageSavingCallback as
var imagesStream = new MemoryStream();
var handleImageSaving = new HandleImageSaving(imagesStream);
options.ImageSavingCallback = handleImageSaving;
document.Save(stream, options);
public class HandleImageSaving : IImageSavingCallback
{
private MemoryStream m_images;
public HandleImageSaving(
MemoryStream i_images)
{
m_images = i_images;
}
void IImageSavingCallback.ImageSaving(ImageSavingArgs args)
{
args.ImageStream = m_images;
args.KeepImageStreamOpen = true;
}
}
After .Save is executed, multiple images are stored in imagesStream, now I need to retrieve image one by one from imagesStream, how can I do it?
Please try using the following sample:
Document doc = new Document(MyDir + #"input.docx");
MemoryStream htmlStream = new MemoryStream();
MemoryStream imagesStream = new MemoryStream();
HtmlSaveOptions options = new HtmlSaveOptions(SaveFormat.Html);
var handleImageSaving = new HandleImageSaving(imagesStream);
options.ImageSavingCallback = handleImageSaving;
doc.Save(htmlStream, options);
DocumentBuilder builder = new DocumentBuilder();
foreach (Stream imgStream in handleImageSaving.ImageStreams)
{
builder.InsertImage(imgStream);
builder.Writeln();
}
builder.Document.Save(MyDir + #"15.12.0.docx");
And the definition of HandleImageSaving class is as follows
public class HandleImageSaving : IImageSavingCallback
{
public ArrayList ImageStreams;
private MemoryStream m_images;
public HandleImageSaving(MemoryStream i_images)
{
ImageStreams = new ArrayList();
m_images = i_images;
}
void IImageSavingCallback.ImageSaving(ImageSavingArgs args)
{
Shape shape = (Shape)args.CurrentShape;
m_images = new MemoryStream(shape.ImageData.ImageBytes);
ImageStreams.Add(m_images);
args.ImageStream = m_images;
args.KeepImageStreamOpen = true;
}
}
Hope, this helps. I work with Aspose as Developer Evangelist.
I'm trying to read an external json to display data on screen. What am I doing worng here?
public void QuarterlyReport(object sender, EventArgs e)
{
JObject qData1 = JObject.Parse(System.IO.File.ReadAllText(#"~/json/quarterlyData.json"));
// read JSON directly from a file
using (StreamReader file = System.IO.File.OpenText(#"~/json/quarterlyData.json"))
using (JsonTextReader reader = new JsonTextReader(file))
{
JObject Qdata2 = (JObject) JToken.ReadFrom(reader);
}
string Qdata = Newtonsoft.Json.JsonConvert.SerializeObject(qData1);
}
public async Task<FileStreamResult> Index()
{
var _reportingService = new ReportingService("https://mysite.jsreportonline.net", "myemail#gmail.com", "password");
var report = await _reportingService.RenderAsync("VyxOYwH7Ze", new { Qdata });
//add the stream to be used by browser
MemoryStream ms = new MemoryStream();
//copy whatever JS is sending to us
report.Content.CopyTo(ms);
//start at content point
ms.Position = 0;
//send this to browser
return File(ms, report.ContentType.MediaType);
}
I can't seem to get the vaule into the variable Qdata. What is it that I am doing wrong in the method?
The line where you declare Qdata:
string Qdata = Newtonsoft.Json.JsonConvert.SerializeObject(qData1);
is not in the same scope as this line:
var report = await _reportingService.RenderAsync("VyxOYwH7Ze", new { Qdata });
Yes, the problem was that
JObject qData1 = JObject.Parse(System.IO.File.ReadAllText(#"~/json/quarterlyData.json"));
And
string Qdata = Newtonsoft.Json.JsonConvert.SerializeObject(qData1);
Needed to be in the same scope as
var report = await _reportingService.RenderAsync("VyxOYwH7Ze", new { Qdata });
I am preparing to using Timeglider to create a timeline. One requirement is the data has to be in JSON format. One requirement for me is it needs to be client side as I do not have access to the servers or central admin.
When I try to do http://webname/_vti_bin/ListData.svc/listname I get an error for access permissions however when I issue it http://webname/subsite/_vti_bin/ListData.svc/listname I have no problem pulling data.
My situation is the list is on the TLD. I tried to follow this post How to retrieve a json object from a sharepoint list but it relates to SP 2007.
To implement pure JSON support in SharePoint 2007, 2010 and so on have a look at this project, http://camelotjson.codeplex.com/. It requires the commercial product Camelot .NET Connector to be installed on the server.
If you don't like to go commercial you can resort to the sp.js library, here is a small example I wrote, enjoy!

Personally, I make HttpHandlers. I install them in the SharePoint isapi folder and the GAC and I can call them just like you might the owssvr.dll. http://servername/_vti_bin/myhttphandelr.dll
Pass it querystring variables or call it from jquery ajax. You can use the httpcontext and make a spcontext from it and have access to all sorts of information from the current location in SharePoint. Then you can javascriptserialize the objects and pass them as JSON. Looking for some code... Hang on... I can't put all the code but this should get you close. I use this to add a submenu to the context menu to allow a user to delete or rename a file if they uploaded it to a library and it is version 1.0 and to collect a file from a library and create a eml file with the selected file(s) as an attachment(s). We don't give our users delete privileges normally. Point being, you can now create a class with just the information you need from SharePoint and pass it as JSON. The only downfall I have with this, is iisreset is required if you make any changes to the dll.
I task schedule a iisreset every night at midnight anyway to keep it fresh and free from memory bloat. I come in the next day and my changes are there. The cool thing is, the spcontext has information about the current location in SharePoint from where it is called. So, http://servername/_vti_bin/myhttphandelr.dll vs http://servername/subsite/library/_vti_bin/myhttphandelr.dll
I might add. Don't try to serialize SharePoint objects. One they are huge, complex objects. Two, I don't think they are marked serializable. Just make you own class and populate it with the values you need from the SharePoint objects.
