  • Performance implications of Synchronous Sockets vs Asynchronous Sockets

    - by Akash Kava
    We are trying to build an SMTP Server to receive mail notifications from various clients over internet. As each of the communication will be longer and it needs to log everything, doing this Asynchronous way is little challenging as well as by using Socket's Asynchronous methods we are not sure of how flow of control and error handling happens. Previously we wrote lot of server/client apps but we always used Synchronous sockets, reason being they are longer sessions and each session also has lot of local data to manage and parsing messages etc. Does anyone have any experience over real performance differences between these two methods? Async calls use ThreadPool which we have experienced many times to just die for no reason. And we fail to restart threadpool etc. In one way Request-Response protocol of HTTP, Async Sockets makes sense, but SMTP/IMAP etc protocols are longer and they have interleaved messages plus state machine of server. So Async methods are really complicated to program. However if anyone can share the performance of Sockets, it will be helpful.

  • midl.exe cannot load mscorlib.tlb

    - by Akash
    I'm trying to use midl to turn an idl file into a tlb. However, when I try I get this warning: warning MIDL2015: failed to load tlb in importlib : mscorlib.tlb and I then get a subsequent error: error MIDL2337 : unsatisfied forward declaration : _Object..... I'm certain that the error is due to the first warning. I've tried the same command on a different machine and it succeeds, so I know that the idl file is correct. I've tried uninstalling the .NET framework and reinstalling it in the hope that that would fix things, but it had no effect. So my question is, what do I need to fix on my machine to allow midl to locate mscorlib.tlb once more?

  • Specifying culture for http request/reponse

    - by Akash
    I have a ReSTful web service which needs to parse culture-sensitive data from the request. This data could either be in an XML body or part of the query string. Is there any acepted way of determining which culture the data is being sent in (and by extension the culture in which the response should be sent)? One option is simply to specify to the clients the culture in which all requests should be sent. A friendlier option seems to be to allow the client to specify the culture. I've considered: a) using the accept-language http header to encode this information. b) using the xml:lang attribute for XML POSTs, and an extra field for query strings (e.g. ...&culture=en-GB) http://www.w3.org/International/questions/qa-accept-lang-locales warns of limitations in using the accept-language header, but most of the warnings seem to center around requests originating from browsers. In my case the requests will come from other applications. All advice greatly appreciated!

  • Inconsistency in passing objects from VBA to .NET via COM

    - by Akash
    I have the following interface defined to expose a .NET class to COM: [InterfaceType(ComInterfaceType.InterfaceIsDual)] [Guid("6A983BCC-5C83-4b30-8400-690763939659")] [ComVisible(true)] public interface IComClass { object Value { get; set; } object GetValue(); void SetValue(object value); } The implementation of this interface is trivial: [ClassInterface(ClassInterfaceType.None)] [Guid("66D0490F-718A-4722-8425-606A6C999B82")] [ComVisible(true)] public class ComClass : IComClass { private object _value = 123.456; public object Value { get { return this._value; } set { this._value = value; } } public object GetValue() { return this._value; } public void SetValue(object value) { this._value = value; } } I have then registered this using RegAsm, and tried to call it from Excel via the following code: Public Sub ComInterop() Dim cc As ComClass Set cc = New ComClass cc.SetValue (555.555) valueByGetter = cc.GetValue valueByProperty = cc.Value cc.Value = 555.555 End Sub When I step throught this code, valueByGetter = 555.5555 and valueByProperty = 555.555 as expected. However, I get an "Object required" runtime error on the final line. Why does setting the value via the setter method work but setting via the property fail? What do I have to change to get the property to work as expected?

  • Upload image from J2ME client to a Servlet

    - by Akash
    I want to send an image from a J2ME client to a Servlet. I am able to get a byte array of the image and send it using HTTP POST. conn = (HttpConnection) Connector.open(url, Connector.READ_WRITE, true); conn.setRequestMethod(HttpConnection.POST); conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded"); os.write(bytes, 0, bytes.length); // bytes = byte array of image This is the Servlet code: String line; BufferedReader r1 = new BufferedReader(new InputStreamReader(in)); while ((line = r1.readLine()) != null) { System.out.println("line=" + line); buf.append(line); } String s = buf.toString(); byte[] img_byte = s.getBytes(); But the problem I found is, when I send bytes from the J2ME client, some bytes are lost. Their values are 0A and 0D hex. Exactly, the Carriage Return and Line Feed. Thus, either POST method or readLine() are not able to accept 0A and 0D values. Any one have any idea how to do this, or how to use any another method?

  • Global Handler in IIS7 (Classic Mode) gives "Failed to Execute" error

    - by Akash Kava
    I have made a custom handler called MyIndexHandler and I want it to handle *.index requests, now as I want this handler to be executed by any website, I installed my handler with following two steps in IIS manager. Add MyIndexHandler.dll in GAC Add Managed Module for *.index, the drop down in IIS displays my index handler correctly so it means it did find it correctly from the GAC. I added Script map for aspnet_isapi.dll for *.index (this is required for classic mode) Now in any of my website if I try xyz.index, my handler does not get called and it returns "Failed to execute URL", now this only happens when IIS is unable to find the mapped handler, but I already have defined mapped handler at IIS level and when i try to add entry in web.config manually for this handler, it tells me you can not define multiple handler, it means that IIS finds my handler, mapping but for some reason it does not execute it.

  • Alternative native api for Process.Start

    - by Akash Kava
    Ok this is not duplicate of "http://stackoverflow.com/questions/2065592/alternative-to-process-start" because my question is something different here. I need to run a process and wait till execution of process and get the output of console. There is way to set RedirectStandardOutput and RedirectStandardError to true, however this does not function well on some machines, (where .NET SDK is not installed), only .NET runtime is installed, now it works on some machines and doesnt work on some machines so we dont know where is the problem. I have following code, ProcessStartInfo info = new ProcessStartInfo("myapp.exe", cmd); info.CreateNoWindow = true; info.UseShellExecute = false; info.RedirectStandardError = true; info.RedirectStandardOutput = true; Process p = Process.Start(info); p.WaitForExit(); Trace.WriteLine(p.StandardOutput.ReadToEnd()); Trace.WriteLine(p.StandardError.ReadToEnd()); On some machines, this will hang forever on p.WaitForExit(), and one some machine it works correctly, the behaviour is so random and there is no clue. Now if I can get a real good workaround for this using pinvoke, I will be very happy.

  • How to create Encryption Key for Encryption Algorithms?

    - by Akash Kava
    I want to use encryption algorithm available in .Net Security namespace, however I am trying to understand how to generate the key, for example AES algorithm needs 256 bits, that 16 bytes key, and some initialization vector, which is also few bytes. Can I use any combination of values in my Key and IV? e.g. all zeros in Key and IV are valid or not? I know the detail of algorithm which does lots of xors, so zero wont serve any good, but are there any restrictions by these algorithms? Or Do I have to generate the key using some program and save it permanently somewhere?

  • Where to get MSDN Help Viewer for 2010 like earlier MSDN with Index, Tree and one window?

    - by Akash Kava
    I upgraded to Visual Studio 2010 RC, and I remember filling one big form for MSDN help improvement campaign and I was wondering I will get to see a Help Viewer like MSDN included in Visual Studio 2008, which included One Program (Not IE), Index and the way to view preferred language setting. Google results shows that there were headlines that Microsoft Help Viewer released for 2010 RC, but where is it? is it the same one which opens in IE and has absolute difficult way to view it? Current MSDN opening in IE is so inconvenient, there is no index, there is no grouping of content, like I typed search for TextBox and it showed up for ASP.NET, WinForms and I got lost to find out the reference in multiple pages for search results.

  • user agent checking for ios6

    - by Akash Saikia
    I am trying to check whether client opening the page is using iOS6 or not. var startIndex = navigator.userAgent.search(/OS/i) + 2; var endIndex = navigator.userAgent.search(/like/i); var iOSVersion = parseInt(navigator.userAgent.substr(startIndex,endIndex - startIndex).trim()); this.iOSVersion = true; if(!isNaN(iOSVersion)){ this.iOSVersion = iOSVersion; } else if(Ext.is.Desktop){ this.iOSVersion = true; } The above code works well for all the versions of browsers. But incase of using it in iOS6, it shows as iOS5. Searched for the same thing, but I didn't find a solution. May be I am still not done with searching for this, doing side by side search and hoping if some one has faced this issue before. Any suggestions or updations?

  • Button Template does not render Image clearly.

    - by Akash Kava
    Here is my button template, <Microsoft_Windows_Themes:ButtonChrome x:Name="Chrome" Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}" RenderDefaulted="{TemplateBinding IsDefaulted}" RenderMouseOver="{TemplateBinding IsMouseOver}" RenderPressed="{TemplateBinding IsPressed}"> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition Width="Auto"/> <ColumnDefinition/> </Grid.ColumnDefinitions> <Image Source="{TemplateBinding ImageSource}" RenderOptions.BitmapScalingMode="NearestNeighbor" SnapsToDevicePixels="True" HorizontalAlignment="Center" VerticalAlignment="Center" Stretch="None" /> <ContentPresenter Grid.Column="1" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" RecognizesAccessKey="True"/> </Grid> </Microsoft_Windows_Themes:ButtonChrome> Now you can see as per this question My Images are blurry on StackOverflow I tried .. RenderOptions.BitmapScalingMode="NearestNeighbor" On all levels, grid, chrome .. and tried various combinations of SnapsToDevicePixels but images just wont show up correctly. I set Stretch=None, image is aligned at center, still why it stretches automatically? here is the output and its very frustrating. Actual size of the image is 16x16 but I some how figured out by using Windows Maginifier that no matter what I do, the image is actually trying to render as 20x20, for the bigger images its even cropping the right most and bottom part. I think image should be rendered correctly 16x16 when Stretch=None, can anyone clarify whats problem here?

  • Binding for MinWidth property does not work in Silverlight

    - by Akash Kava
    I have noticed something very unusual today, I need to bind "MinWidth" property of TextBlock to some value, however following example does not work. It only accepts MinWidth at a time of creation, but after that it is not affected at all if LeftWidth property is changed at runtime, however if I bind LeftWidth property to WidthProperty it works well. Binding b = new Binding("LeftWidth"); // following never changes layout of control tb.SetBinding(TextBlock.MinWidthProperty,b); However, this one works correctly, // following never changes layout of control tb.SetBinding(TextBlock.WidthProperty,b); Now I also did hook events and tried to do InvalidateMeasure and InvalidateArrange on TextBlock, but it has no effect. Seems like Changing MinWidth Property after layout pass does not work at all. Can it be a bug in Silverlight? or Does anyone have any idea at all why MinWidth does not redo the layout?

    I am using MPMediaQuery to get all artists from library. Its returning unique names I guess but the problem is I have artists in my library like "Alice In Chains" and "Alice In Chains ". The second "Alice In Chains" has some white spaces at the end, so it returns both. I dont want that. Heres the code... MPMediaQuery *query=[MPMediaQuery artistsQuery]; NSArray *artists=[query collections]; artistNames=[[NSMutableArray alloc]init]; for(MPMediaItemCollection *collection in artists) { MPMediaItem *item=[collection representativeItem]; [artistNames addObject:[item valueForProperty:MPMediaItemPropertyArtist]]; } uniqueNames=[[NSMutableArray alloc]init]; for(id object in artistNames) { if(![uniqueNames containsObject:object]) { [uniqueNames addObject:object]; } } Any ideas?

  • Difference between Cloud and Virtualization

    - by Akash Kava
    Ops: This does not belong to ServerFault because it focuses on Programing Architecture. I have following questions regarding differences between Cloud and Virtualization.. How Cloud is different then Virtualization? Currently I tried to find out pricing of Rackspace, Amazone and all similar cloud providers, I found that our current 6 dedicated servers came cheaper then their pricing. So how one can claim cloud is cheaper? Is it cheaper only in comparison of normal hosting? We re organized our infrastructure in virtual environment to reduce or configuration overhead at time of failure, we did not have to rewrite any peice of code that is already written for earlier setup. So moving to virtualization does not require any re programming. But cloud is absoltely different and it will require entire reprogramming right? Is it really worth to recode when our current IT costs are 3-4 times lower then cloud hosting including raid backups and all sort of clustering for high availability? New programming architecture means new overheads of training staff, new methods of testing and new deployment schemes, does it justify over "on demand resource usage" words of cloud? We are having current development architecture with simple Server side ASP.NET WebServices with no local context and on client side Flex/Silverlight which offers pretty good REST architecture and its highly scalable. How does cloud differs from REST model of deployment? On storage, SQL Server or MySQL offers pretty good replication and high availibility then what is advantage in cloud? Data guarantee, one of our vendor hosting some other customer's app on cloud (one of most used), lost Entire Hard Disk (the virtual) and entire module in first 6 months. Second provider said its your duty to take backup, fine I agree, but no provider gives SLA for data guarantee, they give 99% uptime. However in most business apps, uptime is less important then data integrity. In our 10 years of dedicated hosting experience we had only one hard disk crash. This makes me little skeptical to go for cloud and loosing control over data. And I feel its just a big marketing buzz to sell virtulization in different form. Size of data, currently all providers charge very heavy for large data, if you are hosting only below 100GB cloud can be good alternative, but I think virtual servers and dedicated servers above 100GB to few TBs are still cheaper. Why would want to pay so high on cloud when there is no data guarentee as well as it doesnt say anything about redundancy. (I wish SO had something for spell check for Internet Explorer, sorry for wrong spellings in my post)

  • Can I control object creation using MEF?

    - by Akash
    I need to add some extension points to our existing code, and I've been looking at MEF as a possible solution. We have an IRandomNumberGenerator interface, with a default implementation (ConcreteRNG) that we would like to be swappable. This sounds like an ideal scenario for MEF, but I've been having problems with the way we instantiate the random number generators. Our current code looks like: public class Consumer { private List<IRandomNumberGenerator> generators; private List<double> seeds; public Consumer() { generators = new List<IRandomNumberGenerator>(); seeds = new List<double>(new[] {1.0, 2.0, 3.0}); foreach(var seed in seeds) { generators.Add(new ConcreteRNG(seed); } } } In other words, the consumer is responsible for instantiating the RNGs it needs, including providing the seed that each instance requires. What I'd like to do is to have the concrete RNG implementation discovered and instantiated by MEF (using the DirectoryCatalog). I'm not sure how to achieve this. I could expose a Generators property and mark it as an [Import], but how do I provide the required seeds? Is there some other approach I am missing?

    Background : I have some Application Data. i.e. the Database, come important config files. This data is vital for the application to start else it is exited. Problem : Where should I store this data. i.e in which folder and where. Right Now (This is wrong) it is stored in a folder in Debug/App_Data. But is causing issues in git and when we publish the App the data is not found. So where can we store this folder ? Present Structure is "WpfApplication2\WpfApplication2\bin\Debug" These Files need to be present when the app is started. So they need to be a part of the app itself.
