  • Microsoft and the open source community

    - by Charles Young
    For the last decade, I have repeatedly, in my imitable Microsoft fan boy style, offered an alternative view to commonly held beliefs about Microsoft's stance on open source licensing.  In earlier times, leading figures in Microsoft were very vocal in resisting the idea that commercial licensing is outmoded or morally reprehensible.  Many people interpreted this as all-out corporate opposition to open source licensing.  I never read it that way. It is true that I've met individual employees of Microsoft who are antagonistic towards FOSS (free and open source software), but I've met more who are supportive or at least neutral on the subject.  In any case, individual attitudes of employees don't necessarily reflect a corporate stance.  The strongest opposition I've encountered has actually come from outside the company.  It's not a charitable thought, but I sometimes wonder if there are people in the .NET community who are opposed to FOSS simply because they believe, erroneously, that Microsoft is opposed. Here, for what it is worth, are the points I've repeated endlessly over the years and which have often been received with quizzical scepticism. a)  A decade ago, Microsoft's big problem was not FOSS per se, or even with copyleft.  The thing which really kept them awake at night was the fear that one day, someone might find, deep in the heart of the Windows code base, some code that should not be there and which was published under GPL.  The likelihood of this ever happening has long since faded away, but there was a time when MS was running scared.  I suspect this is why they held out for a while from making Windows source code open to inspection.  Nowadays, as an MVP, I am positively encouraged to ask to see Windows source. b)  Microsoft has never opposed the open source community.  They have had problems with specific people and organisations in the FOSS community.  Back in the 1990s, Richard Stallman gave time and energy to a successful campaign to launch antitrust proceedings against Microsoft.  In more recent times, the negative attitude of certain people to Microsoft's submission of two FOSS licences to the OSI (both of which have long since been accepted), and the mad scramble to try to find any argument, however tenuous, to block their submission was not, let us say, edifying. c) Microsoft has never, to my knowledge, written off the FOSS model.  They certainly don't agree that more traditional forms of licensing are inappropriate or immoral, and they've always been prepared to say so.  One reason why it was so hard to convince people that Microsoft is not rabidly antagonistic towards FOSS licensing is that so many people think they have no involvement in open source.  A decade ago, there was virtually no evidence of any such involvement.  However, that was a long time ago.  Quietly over the years, Microsoft has got on with the job of working out how to make use of FOSS licensing and how to support the FOSS community.  For example, as well as making increasingly extensive use of Github, they run an important FOSS forge (CodePlex) on which they, themselves, host many hundreds of distinct projects.  The total count may even be in the thousands now.  I suspect there is a limit of about 500 records on CodePlex searches because, for the past few years, whenever I search for Microsoft-specific projects on CodePlex, I always get approx. 500 hits.  Admittedly, a large volume of the stuff they publish under FOSS licences amounts to code samples, but many of those 'samples' have grown into useful and fully featured frameworks, libraries and tools. All this is leading up to the observation that yesterday's announcement by Scott Guthrie marks a significant milestone and should not go unnoticed.  If you missed it, let me summarise.   From the first release of .NET, Microsoft has offered a web development framework called ASP.NET.  The core libraries are included in the .NET framework which is released free of charge, but which is not open source.   However, in recent years, the number of libraries that constitute ASP.NET have grown considerably.  Today, most professional ASP.NET web development exploits the ASP.NET MVC framework.  This, together with several other important parts of the ASP.NET technology stack, is released on CodePlex under the Apache 2.0 licence.   Hence, today, a huge swathe of web development on the .NET/Azure platform relies four-square on the use of FOSS frameworks and libraries. Yesterday, Scott Guthrie announced the next stage of ASP.NET's journey towards FOSS nirvana.  This involves extending ASP.NET's FOSS stack to include Web API and the MVC Razor view engine which is rapidly becoming the de facto 'standard' for building web pages in ASP.NET.  However, perhaps the more important announcement is that the ASP.NET team will now accept and review contributions from the community.  Scott points out that this model is already in place elsewhere in Microsoft, and specifically draws attention to development of the Windows Azure SDKs.  These SDKs are central to Azure development.   The .NET and Java SDKs are published under Apache 2.0 on Github and Microsoft is open to community contributions.  Accepting contributions is a more profound move than simply releasing code under FOSS licensing.  It means that Microsoft is wholeheartedly moving towards a full-blooded open source approach for future evolution of some of their central and most widely used .NET and Azure frameworks and libraries.  In conjunction with Scott's announcement, Microsoft has also released Git support for CodePlex (at long last!) and, perhaps more importantly, announced significant new investment in their own FOSS forge. Here at Solidsoft we have several reasons to be very interested in Scott's announcement. I'll draw attention to one of them.  Earlier this year we wrote the initial version of a new UK Government web application called CloudStore.  CloudStore provides a way for local and central government to discover and purchase applications and services. We wrote the web site using ASP.NET MVC which is FOSS.  However, this point has been lost on the ladies and gentlemen of the press and, I suspect, on some of the decision makers on the government side.  They announced a few weeks ago that future versions of CloudStore will move to a FOSS framework, clearly oblivious of the fact that it is already built on a FOSS framework.  We are, it is fair to say, mildly irked by the uninformed and badly out-of-date assumption that “if it is Microsoft, it can't be FOSS”.  Old prejudices live on.

  • Using System.Security.SecureString in .NET Remoting App?

    - by Beaner
    I am developing a Remoting application where a client looks up store specific information to login to a web server. It sets the user name and passwords in a class that stores the properties as System.Security.SecureString. I then try to pass the class with the login credentials to a server object that uses it to connect to the web host, get and some information back. When I call the server method I this error:Type 'System.Security.SecureString' in Assembly 'mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' is not marked as serializable. The class that contains the SecureStrings is marked as serializeable, and this was working while developing until I added the SecureString properties. Is there something I need to do to make this work, or am I going to have to change SecureString to String?

  • Exception converting Office files to PDF using ABCpdf.NET onWindows Server 2008

  • ASP.Net: IHttpAsyncHandler and AsyncProcessorDelegate

    - by ctrlShiftBryan
    I have implemented an IHttpAsyncHandler. I am making about 5 different AJAX calls from a webpage that has widgets to that handler. One of those widgets takes about 15 seconds to load(because of a large database query) the others should all load in under a second. The handler is responding in a synchronous manner. I am getting very inconsistent results. The ProcessRequest method is using Session and other class level variables. Could that be causing different requests to use the same thread instead each there own? I'm getting this... Request1 --- response 1 sec Request2 --- response 14 sec Request3 --- response 14.5 sec Request4 --- response 15 sec Request5 --- response 15.5 sec but I'm looking for something more like this... Request1 --- response 1 sec Request2 --- response 14 sec Request3 --- response 1.5 sec Request4 --- response 2 sec Request5 --- response 1.5 sec Without posting too much code my implementation of the IHttpAsyncHandler methods are pretty standard. private AsyncProcessorDelegate _Delegate; protected delegate void AsyncProcessorDelegate(HttpContext context); IAsyncResult IHttpAsyncHandler.BeginProcessRequest(HttpContext context, AsyncCallback cb, object extraData) { _Delegate = new AsyncProcessorDelegate(ProcessRequest); return _Delegate.BeginInvoke(context, cb, extraData); } void IHttpAsyncHandler.EndProcessRequest(IAsyncResult result) { _Delegate.EndInvoke(result); } Putting a debug break point in my IHttpAsyncHandler.BeginProcessRequest method I can see that the method isn't being fired until the last Process is complete. Also my machine.config has this entry... processModel autoConfig="true" with no other properties set. What else do I need to check for?

  • C# / WPF / .NET - Drag and drop to Desktop / Explorer

    - by Dänu
    Hey Guys Following my scenario. I got an Application which loads a Filestructure (Folders, Files) from a Database into a WPF ListView. Now I'd like to grab a file from this ListView, drag it over my Desktop (or some open explorer window) and drop it there. Basic Drag and Drop, nothing fancy. This sounds like a "standard" function for a windows application - but google won't help. So how can I achieve this? Interops? Thanks Edit: Thanks for the solution, I still had to do some googling. Here's my complete solution.

  • Is there a way to serialize a .Net MailMessage object

    - by Matt Dawdy
    I am trying to write a proc that will take in as a parameter a MailMessage object, and the split it apart to store the subject, body, to addresses, from address, and attachments (the hard part) in a database so the email can be sent at some point in the future. My first take on this was to rip out the parts I need and store them in a database, and that works great except for attachments. I can't figure out how to loop through the collection and then actually do anything with them. It there an easy way to serialize a MailMessage object that will actually take the content of the attachments with it? Am I doing this all wrong? Has anyone done this before?

  • Telerik ASP.NET AJAX - Ajax Update Label with dynamic created Docks

    - by csharpnoob
    Hi, i try to Update a simple Label on Close Event of dynamic created RadDock. Works fine so far, Label gets the correct values but doesnt updates it. RadDock dock = new RadDock(); dock.DockMode = DockMode.Docked; dock.UniqueName = Guid.NewGuid().ToString(); dock.ID = string.Format("RadDock{0}", dock.UniqueName); dock.Title = slide.slideName; dock.Text = string.Format("Added at {0}", DateTime.Now); dock.Width = Unit.Pixel(300); dock.AutoPostBack = true; dock.CommandsAutoPostBack = true; dock.Command += new DockCommandEventHandler(dock_Command); ... void dock_Command(object sender, DockCommandEventArgs e) { Status.Text = "Removed " + ((RadDock)sender).Title + " " + ((RadDock)sender).Text; } I tried to do this: RadAjaxManager1.AjaxSettings.AddAjaxSetting(dock, Status, null); while creating the docks, but on runtime i get a NullReference Excepetion. On a Button registered with the RadAjaxManager it works to show the value assigned by dock_command. protected void Button1_Click(object sender, EventArgs e) { Status.Text = Status.Text; } UPDATE: The RadAjaxManager was created with integrated Wizzard of VS2008. Can't select the Docks, because the are generated while runtime. On Backend its included in AutoCompletion, so the NullReference has nothing to do with the AjaxManager itself. Like i said, works fine with the Button. <telerik:RadAjaxManager ID="RadAjaxManager1"> <telerik:AjaxSetting AjaxControlID="Button1"> <UpdatedControls> <telerik:AjaxUpdatedControl ControlID="Label1"></telerik:AjaxUpdatedControl> </UpdatedControls> </telerik:AjaxSetting>

    - by NLV
    Hello I've a windows forms application with MS SQL Server 2005 as the back end. I have written code in the form to call few stored procedures using SqlConnection, SqlCommand objects and i properly dispose everything. I've disposed sqlcommand object by calling oSqlCommand.Dispose() But i witnessed my application consuming huge amount of memory. I basically pass large XML files as SqlParameters. I finally decided to memory profile it using RedGate Memory profiler and i noticed that the System.Data.SqlClient.SqlParameters are not disposed. Any insights on this? Thanks NLV

  • Setting html attribute that is reserved keyword in Html.CheckBoxFor in ASP.NET MVC

    - by dormisher
    Hi, I am using the HtmlHelper to create a checkbox in my view like so: <%= Html.CheckBoxFor(model = model.SeatOnly, new { checked = "checked" })% However, an error is being thrown as checked is a reserved keyword. I have found a couple of people saying that you must use the 'reserved word prefix' and simply put an uderscore in front of the attribute like so: <%= Html.CheckBoxFor(model = model.SeatOnly, new { _checked = "checked" })% This does not generate an error but in the generated html the attribute is actually '_checked' which means it doesn't work (if I use firebug and remove the underscore the attribute then takes effect). Does anyone know a way around this while still using CheckBoxFor? Thanks

  • Programmatically set the DPI from a .net 2.0 WinForms application

    - by Stef
    I want to run my application on 96dpi, no matter what the dpi size from Windows is set to. It is possible ? ' Edit ' I found that using the Scale() method and resizing the font will almost do the trick. public class MyForm : Form { private static bool ScaleDetected = false; const float DPI = 80F; protected override void OnPaint(PaintEventArgs e) { base.OnPaint(e); if (!ScaleDetected) { Graphics g = e.Graphics; float factorX = DPI / g.DpiX; float factorY = DPI / g.DpiY; SizeF newSize = new SizeF(factorX, factorY); AutoScaleDimensions = newSize; AutoScaleMode = AutoScaleMode.Dpi; Scale(newSize); Font = new Font(Font.FontFamily, Font.Size * factorX); ScaleDetected = true; } } } However when using this 'trick' in a MDI application using Janus Controls, the main form is resized, but for some other forms, the scaling + changed font are not applied.

  • Self hosted WCF ServiceHost/WebServiceHost Concurrency/Peformance Design Options (.NET 3.5)

    - by Kyle
    So I'll be providing a few functions via a self hosted (in a WindowsService) WebServiceHost (not sure how to process HTTP GET/POST with ServiceHost), one of which may be called a large amount of the time. This function will also rely on a connection in the appdomain (hosted by the WindowsService so it can stay alive over multiple requests). I have the following concerns and would be oh so thankful for any input/thoughts/comments: Concurrent access - how does the WebServiceHost handle a bunch of concurrent requests. Are they queued and processes sequentially or are new instances of the contracts automagically created? WebServiceHost - WindowsService communication - I need some form of communication from the WebServiceHost to the hosting WindowsService for things like requesting a new session if one does not exist. Perhaps implementing a class which extends the WebServiceHost with events which the WindowsService subscribes to... (unless there is another way I can set off an event in the WindowsService when a request is made...) Multiple WebServiceHosts or Contracts - Would it give any real performance gain to be running multiple WebServiceHost instances in different threads (one per endpoint perhaps?) - A better understanding of the first point would probably help here. WSDL - I'm not sure why (probably just need to do more reading), but I'm not sure how to get the WebServiceHost base endpoint to respond with a WDSL document describing the available contract. Not required as all the operations will be done via GET requests which will not likely change, but it would be nice to have... That's about it for the moment ;) I've been reading a lot on WCF and wish I'd gotten into it long ago, but definitely still learning.

  • Binding not writing to datasource on .NET Compact Framework Form -- works on Full Framework

    - by Dave Welling
    I have a problem with a bound user control writing back to it's datasource on a NetCF forms application. The application is too complex to post code, so I made a toy version to show you. I create a form, usercontrol with a combobox, a class (testBind) and another class (TestLookup). I bind a property of the usercontrol ("value") to a property ("selectedValue") on the testBind class. The testBind class implements INotifyPropertyChanged. I create a few fascade methods on the user control to bind the contained combobox to a BindingList(of TestLookup). I create a button to show the value of the testBind bound property (in a MessageBox). The messagebox returns "-1" every time regardless of the combobox entry selected. I can take the EXACT same code, paste it in a full framework Forms app and it will return the correct value of the selected combobox entry. Imports System.ComponentModel Public Class Form2 Inherits Form Private _testBind1 As testBind Private _testUserControlX As UserControlX Friend WithEvents _buttonX As System.Windows.Forms.Button Public Sub New() _buttonX = New System.Windows.Forms.Button _buttonX.Location = New System.Drawing.Point(126, 228) _buttonX.Size = New System.Drawing.Size(70, 21) _testBind1 = New testBind _testUserControlX = New UserControlX() Dim _lookup As New System.ComponentModel.BindingList(Of TestLookup)() _lookup.Add(New TestLookup(1, "text1")) _lookup.Add(New TestLookup(2, "text2")) _testUserControlX.DataSource = _lookup _testUserControlX.DisplayMember = "Text" _testUserControlX.ValueMember = "ID" _testUserControlX.DataBindings.Add("Value", _testBind1, "SelectedID", False, DataSourceUpdateMode.OnValidation) MinimizeBox = False Controls.Add(_testUserControlX) Controls.Add(_buttonX) End Sub Private Sub ButtonX_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles _buttonX.Click MessageBox.Show(_testBind1.SelectedID.ToString()) End Sub Public Class testBind Implements System.ComponentModel.INotifyPropertyChanged Private _selectedRow As Integer = -1 Public Event PropertyChanged(ByVal sender As Object, ByVal e As System.ComponentModel.PropertyChangedEventArgs) Implements System.ComponentModel.INotifyPropertyChanged.PropertyChanged Protected Sub OnPropertyChanged(ByVal PropertyName As String) RaiseEvent PropertyChanged(Me, New PropertyChangedEventArgs(PropertyName)) End Sub Public Property SelectedID() As Integer Get Return _selectedRow End Get Set(ByVal value As Integer) _selectedRow = value OnPropertyChanged("SelectedID") End Set End Property End Class Public Class TestLookup Private _text As String Private _id As Integer Public Sub New(ByVal id As Integer, ByVal text As String) _text = text _id = id End Sub Public Property ID() As Integer Get Return _id End Get Set(ByVal value As Integer) _id = value End Set End Property Public Property Text() As String Get Return _text End Get Set(ByVal value As String) _text = value End Set End Property End Class End Class Public Class UserControlX Inherits System.Windows.Forms.UserControl Friend WithEvents ComboBox1 As System.Windows.Forms.ComboBox Public Sub New() Me.ComboBox1 = New System.Windows.Forms.ComboBox Me.Controls.Add(Me.ComboBox1) End Sub Public Property Value() As Integer Get Return ComboBox1.SelectedValue End Get Set(ByVal value As Integer) ComboBox1.SelectedValue = value End Set End Property Public Property DataSource() As Object Get Return ComboBox1.DataSource End Get Set(ByVal value As Object) ComboBox1.DataSource = value End Set End Property Public Property ValueMember() As String Get Return ComboBox1.ValueMember End Get Set(ByVal value As String) ComboBox1.ValueMember = value End Set End Property Public Property DisplayMember() As String Get Return ComboBox1.DisplayMember End Get Set(ByVal value As String) ComboBox1.DisplayMember = value End Set End Property End Class

  • Best Non-Microsoft/.NET Development Blogs and Podcasts

    - by Mark Lubin
    I really don't want to rile anyone's feathers and I really enjoy blogs like Joel, Coding Horror, Scott Hanselman, etc. However, what are some good blogs/podcasts that focus on other platforms besides Microsoft based ones or maybe even no particular platform at? In particular I am interested in areas like Python, Ruby, Java, C, but any area besides Microsoft fits the bill. There may be other similar questions to this but I think this one is unique since we might get some answers we wouldn't see otherwise, that is, everyone knows Coding Horror is great. Please try to refrain from religious debates; the content of the blog is more important than the platform they are talking about, I just want to get an idea of what is out there and worth the time.

  • Using .NET's HttpWebRequest to download a multitude of files in a row

    - by Cornelius
    I have an application that needs to download several files in a row in succession (sometimes a few thousand). However, what ends up happening when several files need to be downloaded is I get an exception with an inner exception of type SocketException and the error code 10048 (WSAEADDRINUSE). I did some digging and basically it's because the server has run out of sockets (and they are all waiting for 240s or so before they become available again) - not coincidentally it starts happening around the 1024 file range. I would expect that the HttpWebRequest/ServicePointManager would be reusing my connection, but apparently it is not (and the files are https, so that may be part of it). I never saw this problem in the C++ code that this was ported from (but that doesn't mean it didn't ever happen - I'd be surprised if it was, though). I am properly closing the WebRequest object and the HttpWebRequest object has KeepAlive set to true by default. Next my intent is to fiddle around with ServicePointManager.SetTcpKeepAlive(). However, I can't see how more people haven't run into this problem. Has anyone else run into the problem, and if so, what did you do to get around it? Currently I have a retry scheme that detects this error and waits it out, but that doesn't seem like the right thing to do. Here's some basic code to verify what I'm doing (just in case I'm missing closing something): WebRequest webRequest = WebRequest.Create(uri); webRequest.Method = "GET"; webRequest.Credentials = new NetworkCredential(username, password); WebResponse webResponse = webRequest.GetResponse(); try { using(Stream stream = webResponse.GetResponseStream()) { // read the stream } } finally { webResponse.Close() }

  • FluentPath: a fluent wrapper around System.IO

    .NET is now more than eight years old, and some of its APIs got old with more grace than others. System.IO in particular has always been a little awkward. Its mostly static method calls (Path.*, Directory.*, etc.) and some stateful classes (DirectoryInfo, FileInfo). In these APIs, paths are plain strings. Since .NET v1, lots of good things happened to C#: lambda expressions, extension methods, optional parameters to name just a few. Outside of .NET, other interesting things happened as well.
