  • Something wrong with this gtk# class for a window?

    - by Isaiah
    Learning C#, I feel so guilty for loving it. I'm a microsoft hater. Anyways I'm trying out gtk# and just trying out some simple stuff. I've made a class for the main window and MonoDevelop is complaining about this code, which I swear was just fine a second ago. public class mwin{ protected Window win = new Window("test program--"); public mwin(){ //Configure the parts win.SetDefaultSize(300,500); } public void showWin(){ win.ShowAll(); } } win.SetDefaultSize(300,500); }--<(here it says "} expected") But obviously I have a closing brace! Am I missing something? [edit] here's whole code. The color stuff was some stuff I was playing around with to color the window, but I didn't finish because the error started. I'm sure it's not the color stuff because it still has an error when I comment them out. http://codepaste.net/b2mwys

  • python len calculation

    - by n00bz0r
    I'm currently trying to build a RDP client in python and I came across the following issue with a len check; From: http://msdn.microsoft.com/en-us/library/cc240836%28v=prot.10%29.aspx "81 2a - ConnectData::connectPDU length = 298 bytes Since the most significant bit of the first byte (0x81) is set to 1 and the following bit is set to 0, the length is given by the low six bits of the first byte and the second byte. Hence, the value is 0x12a, which is 298 bytes." This sounds weird. For normal len checks, I'm simply using : struct.pack("h",len(str(PacketLen))) but in this case, I really don't see how I can calculate the len as described above. Any help on this would be greatly appreciated !

  • Using MicrosoftReportViewer with Web Forms programmatically

    - by user283897
    Hi, I'm repeating my question because the prior one under this topic was lost. Could you please help me? I want to use MicrosoftReportViewer for Web Forms so that the DataSource be set programmatically. There is some sample code on the Internet for Windows Forms but I haven't found anything for Web Forms. For example, here is some code I've tried to use. It gives no errors but nothing is displayed. How should I modify the code to display a table in the ReportViewer? Imports System.Data Imports Microsoft.Reporting.WebForms Partial Class TestReportViewer Inherits System.Web.UI.Page Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load CreateReport() End Sub Sub CreateReport() Dim dt As DataTable Dim rpt As ReportDataSource dt = New DataTable("Sample") With dt .Columns.Add("No", GetType(Integer)) .Columns.Add("Name") .Rows.Add(1, "A1") .Rows.Add(2, "A2") .Rows.Add(3, "A3") .Rows.Add(4, "A4") .AcceptChanges() End With rpt = New ReportDataSource rpt.DataMember = "Sample" rpt.Value = dt rpt.Name = "test" With ReportViewer1 .LocalReport.DataSources.Add(rpt) .DataBind() .LocalReport.Refresh() End With End Sub End Class

  • Why is there no .NET Community Process?

    - by michielvoo
    I was doing some research into general topics of software engineering and I came across the Java Community Process website: The JCP is the mechanism for developing standard technical specifications for Java technology. Anyone can register for the site and participate in reviewing and providing feedback for the Java Specification Requests (JSRs), and anyone can sign up to become a JCP Member and then participate on the Expert Group of a JSR or even submit their own JSR Proposal. Seems like a good idea to me, and there are lots of very well written specifications and reference implementations on the JCP website. So why is there no .NET Community Process? Is that something that Microsoft could or should start? Maybe they could install it on Codeplex.net and hand over the keys to the community.

  • What is my problem with ASP.NET pubslishing?

    - by Shankarooni
    I am done testing my site and I want to upload it to a site like this http://www.university.edu/mydepartment/myname the admin told me the server runs on .NET 3.5. So i used Linq ... now i tried to upload the site by two ways: when i just copy everything (with modification of web.config database settings) i get an error: CS0246: The type or namespace name 'DataClassesDataContext' could not be found (are you missing a using directive or an assembly reference?) Version Information: Microsoft .NET Framework Version:2.0.50727.3082; ASP.NET Version:2.0.50727.3082 Note here it says version 2.0 did he just lie to me? or its my configuration mistake? anyway, i added the reference, nothing changes. I tried also publishing (Build, publish) with option to keep the pre-comiled site updatable, and I get one line saying: this is a makefile and should be deleted! what is going on?

  • Timer applications running under lock on Windows Phone 7

    - by cpedros
    Under the current Windows Phone 7 Application Certification Requirements (pdf) applications running under lock must "stop any ... active timers" (section 6.3.1). However looking out on Marketplace there are a number of timer/stopwatch apps claiming to run under lock and also allow lock to be disabled in their settings. How are these apps certified or is there some loosening on the restrictions by Microsoft if the app allows the user to make that decision? Also some of these apps also suggest they continue even when the app is exited or when the device off. Is it the case that they are not truly running under these circumstances, i.e. the timers either start where they left off when reactivated, or perhaps use the OS time to work out the time elapsed between tombstoning and reactivation? In these circumstance I also presume it is not possible for the app to notify the user when the timer completes?

  • What information about me and my system do compilers add to executeables?

    - by I can't tell you my name.
    I'm currently using Microsoft Visual Studio 2010. If we say that we give 10 different people a copy of MSVC 10 and a short C++ Hello, World listing. They all create a new project using exactly the same settings, add a new cpp file with the Hello, World program and compile it. Do they all get the exactly same binary? If not, what are the exact differences? What information about my system does MSVC add to my executeable? Paranoia!

  • Is it a good idea to use .Net for commercial software?

    - by user146780
    I was playing around with .Net reflector today and realized that Miicrosoft's entire Expression suite is written in .Net. As a result I was pretty much able to see the underlying code for expression. This makes it far easier than binary to break copy protection. I think that that's a big deal. Is it generally recommended to make commercial software in .Net where it is fairly easy to see the source code down to the variable names? I was surprised that Microsoft didn't at least dotfescate it. Thanks

  • MessageContract serialization with DCS

    - by kurtaj
    Is there a way to make the DataContractSerializer serialize a [MessageContract] the same way it appears when transmitted over SOAP? I have a class that appears as follows on the wire for a WCF call: <TestRequest xmlns="http://webservices.test.com/ServiceTest/1.1"> <Name>Just Me</Name> </TestRequest> When serializing using the DCS, it looks like this: <TestRequest xmlns:i="http://www.w3.org/2001/XMLSchema-instance" z:Id="1" xmlns:z="http://schemas.microsoft.com/2003/10/Serialization/" xmlns="http://schemas.datacontract.org/2004/07/ServiceTest"> <_x003C_Name_x003E_k__BackingField z:Id="2">Just Me</_x003C_Name_x003E_k__BackingField> </TestRequest> I'm convinced this inconsistency is because my class is marked up as a message contract instead of a data contract: [MessageContract] [Serializable] public class TestRequest { [MessageBodyMember] public string Name { get; set; } } Is there a way to make the DCS serialize messages the same way WCF does when it creates a SOAP message?

  • [PRISM2] Added view does not appear on screen

    - by Jeaffrey Gilbert
    Why my "mainRegion.Activate(view);" doesn't display the view on screen? It only works if I remove the default view that registered (RegisterViewWithRegion) in ModuleInit.cs though I don't put .Activate() after I added a View. But a problem occurs if I move to other module, and get back to module which default view has been removed, I get blank page. Any clues? Thank you. *) I prefer not to remove default view, but only with Activate(view) can show the View I want as explained in my reference. reference: http://msdn.microsoft.com/en-us/library/dd458899.aspx

  • In what specific areas has F# proven more applicable than C#?

    - by Peter McGrattan
    Over the last few years F# has evolved into one of Microsoft's fully supported languages employing many ideas incubated in OCaml, ML and Haskell. Over the last several years C# has extended it's general purpose features by introducing more and more functional language features: LINQ (list comprehension), Lamdas, Closures, Anonymous Delegates and more... Given C#'s adoption of these functional features and F#'s taxonomy as an impure functional language (it allows YOU to access framework libraries or change shared state when a function is called if you want to) there is a strong similarity between the two languages although each has it's own polar opposite primary emphasis. I'm interested in any successful models employing these two languages in your production polyglot programs and also the areas within production software (web apps, client apps, server apps) you have written in F# in the past year or so that you would previously have written in C#. EDIT: Altered title with the intent of reducing perceived ambiguity.

  • Where to store things like user pictures using Azure? Blob Storage?

    - by n26
    I have just migrated a project of mine for test cases to Microsoft's azure. But for functionalities similar to an avatar upload I need write access to the files on the harddrive. But this is a cloud, so this is not possible. How can I build such functionalities instead? Should I use the Blob Storage or is there a better solution? Does it make sense to store all website images (f.e. layout images) in the Blob Storage? So I would have a Cookie-free Domain for my static content?

  • How to program three editions Light, Pro, Ultimate in one solution

    - by Henry99
    I'd like to know how best to program three different editions of my C# ASP.NET 3.5 application in VS2008 Professional (which includes a web deployment project). I have a Light, Pro and Ultimate edition (or version) of my application. At the moment I've put all in one solution with three build versions in configuration manager and I use preprocessor directives all over the code (there are around 20 such constructs in some ten thousand lines of code, so it's overseeable): #if light //light code #endif #if pro //pro code #endif //etc... I've read in stackoverflow for hours and thought to encounter how e.g. Microsoft does this with its different Windows editions, but did not find what I expected. Somewhere there is a heavy discussion about if preprocessor directives are evil. What I like with those #if-directives is: the side-by-side code of differences, so I will understand the code for the different editions after six months and the special benefit to NOT give out compiled code of other versions to the customer. OK, long explication, repeated question: What's the best way to go?

  • Modifications in default document won't take effect

    - by Wilson
    We have a website developed by ASP.NET+IIS7 and its default document is default.aspx. It works fine. But when we tried to switch the default to index.html, weird things happened. We have modified web.config as follows: <defaultDocument> <files> <clear /> <add value="index.html" /> </files> </defaultDocument> and we have clear everything under C:\Windows\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files``, and restart the worker process. We even changed the name of Default.aspx to dddd.aspx. But everything stays the same when accessing with http://localhost/<MyAppName>/! And when we tried to access with http://localhost/<MyAppName>/index.html, it works fine. Any suggestions would be highly appreciated.

  • How to apply encoding when reading from a serial port

    - by rross
    I'm reading data from a serial port. I read this posting: http://social.msdn.microsoft.com/Forums/en-US/vbgeneral/thread/a709d698-5099-4e37-9e10-f66ff22cdd1e He is writing about many of the issues I have encounter, but in his writing he refers to using: System.Text.Encoding.GetEncoding("Windows-1252"). The problem I'm having is when and how to apply this. There are three potitional spots in my opinion. When the serial port object is define: private SerialPort comport = new SerialPort(); The Event handler: comport.DataReceived += new SerialDataReceivedEventHandler(port_DataReceived); Or when reading the data: string data = comport.ReadExisting(); No matter where I add it. I seem to get errors. How would one use Encoding?

  • How useful are design patterns when it comes to web programming?

    - by Raja
    Background: My organization uses Microsoft .Net (3.5) with SQL Server 2005 as back end. With RAD being the norm and Agile being the widely used process. I have always found using design patterns difficult since it involves a bit more understanding and bit more training. Can you give me some examples where design patterns have solved real time problems in Web programming? What is the criteria for using any design pattern? What is the benefit reaped from it. I know it is a general question but this would help me a bunch.

  • What Visual C++ references are worth a look for a Java programmer looking to get up to speed?

    - by Terry V.
    I have a lot of experience with Java/OO. There are tons of C++ tutorials/references out there, but I was wondering if there are a few key ones that a Java programmer might find useful when making the transition. I will be moving from server-side J2EE to Windows Visual C++ desktop programming. I have googled and found tons of resources, but am overwhelmed and don't know where to best spend my time. I have only a few days to get a good start. Is Visual Studio Express / Microsoft Visual C++ the best IDE for me to start with? Also, any words of wisdom from others who know and work with both languages?
