  • Hosting a VST/DX instrument in C#/C++?

    - by James D
    I'm trying to get a read on the effort level involved in building a barebones virtual instrument host in C++ or C# but I haven't been able to get any hard information. Does anybody know any good starter apps, tutorials, helper libraries for this sort of thing? If it matters, the goal would be to a) accept incoming MIDI events and b) dispatch them to the virtual instrument. In C++ or C#, if possible. Thanks!

  • JMeter - successfull HTTPS recording?

    Greetings, I'm utilizing Jmeter 2.3, which now supports "attempt HTTPS spoofing" under the Proxy Server element. I've tried on several different servers, and have had no success. Has anyone been able to successfully record from an HTTPS source with this setting? Or barring successfully recording, can anyone share a work-around? When available, I simply have HTTPS turned off at the server level, but this is not always feasible. THoughts?

  • Is there an easy way to compare if 2 XDocuments are equal ignoring element/attribute order?

    - by Davy8
    Unit testing my serialization code I found one failed because I had attributes listed in a different order (I'm just comparing the XDocument.ToString() values) and while I could fix that, it really doesn't matter to me in what order the elements or attributes appear as long as they're all there with the right name at the right level of hierarchy. I could probably write a method do this, but I'm wondering if there's an easy built in way I'm not aware of.

  • About x86 architecture assembly and others

    - by caramel1991
    I have the wisdom to learn assembly language,so I search through the internet for the information about this language,and came across some page telling that assembly is a low level native language and varied from one to another processor,so I just wonder,I'm currently running an intel based processor,I've no idea whether it is x86 or what,but I just wanna know,Does it possible for me to learn other processor arhchitecture assembly on my pc??Besides,is there any good books that could guide me through learning the intel architecture assembly.

  • Lamda functions in php

    - by Oden
    Hey, Im really interested in the way of using lamda functions. Does it make sense to use them in a high-level programming language? If yes, why? Is this really just a function embedded in a function, (Like this) or is there more behind?

  • Is there a future for Powerpoint VBA/VSTO?

    - by Sam Russo
    Does anyone know what the future holds for VBA/VSTO programming in Powerpoint? I've been working on a Office automation project and find it frustrating to work with Powerpoint in particular since it seems to be one level below VBA support found in Excel or Word. It feels like MS is trying to phase out support for VBA in PPT since they dropped macro recording in version 2007 and the object model lacks some key features support.

  • How does assembly language interact with something like the Internet?

    - by Maulrus
    So I was thinking about languages the other day, and it struck me that any program written in a compiled language that interacts with the Internet is then translated into assembly that has to interact with the Internet. I've just begun learning a bit of x86 assembly to help me understand C++ a bit better, and I'm baffled by how something so low-level could do something like access the Internet. I'm sure the full answer to this question is much more than would fit in a SO answer, but could somebody give me maybe a basic summary?

  • How to style a treeview in Expression Blend

    - by RobDemo
    (Using Expression Blend 4 RC, Silverlight 3) I have a treeview with several different item templates for different levels. When I open this project in Blend, it seems I can only really style the top-most DataTemplate (via right-click the TreeView in the Objects/Timeline view, Edit Additional Templates-Edit Generated Items (ItemTemplate) - Edit Current). How do I drill down into the level I want and edit those templates? Rob

  • throws SecurityException when signing with the default debug keystore

    - by Omer
    I am receiving a SecurityException since yesterday when I launch the service using signature protection level for permission with the default debug keystore. The strange thing is I wasn't receiving this error before yesterday and I didn't make any security related change. On the other hand, my own keystore using for releases is still working good. Related AndroidManifest.xml part: <permission android:name="com.my.app.privateservices" android:protectionLevel="signature" /> <service android:name=".MyService" android:permission="com.my.app.privateservices" />

  • Understanding VS2010 C# parallel profiling results

    - by Haggai
    I have a program with many independent computations so I decided to parallelize it. I use Parallel.For/Each. The results were okay for a dual-core machine - CPU utilization of about 80%-90% most of the time. However, with a dual Xeon machine (i.e. 8 cores) I get only about 30%-40% CPU utilization, although the program spends quite a lot of time (sometimes more than 10 seconds) on the parallel sections, and I see it employs about 20-30 more threads in those sections compared to serial sections. Each thread takes more than 1 second to complete, so I see no reason for them to work in parallel - unless there is a synchronization problem. I used the built-in profiler of VS2010, and the results are strange. Even though I use locks only in one place, the profiler reports that about 85% of the program's time is spent on synchronization (also 5-7% sleep, 5-7% execution, under 1% IO). The locked code is only a cache (a dictionary) get/add: bool esn_found; lock (lock_load_esn) esn_found = cache.TryGetValue(st, out esn); if(!esn_found) { esn = pData.esa_inv_idx.esa[term_idx]; esn.populate(pData.esa_inv_idx.datafile); lock (lock_load_esn) { if (!cache.ContainsKey(st)) cache.Add(st, esn); } } lock_load_esn is a static member of the class of type Object. esn.populate reads from a file using a separate StreamReader for each thread. However, when I press the Synchronization button to see what causes the most delay, I see that the profiler reports lines which are function entrance lines, and doesn't report the locked sections themselves. It doesn't even report the function that contains the above code (reminder - the only lock in the program) as part of the blocking profile with noise level 2%. With noise level at 0% it reports all the functions of the program, which I don't understand why they count as blocking synchronizations. So my question is - what is going on here? How can it be that 85% of the time is spent on synchronization? How do I find out what really is the problem with the parallel sections of my program? Thanks.

  • Learning to write organized and modular programs

    - by Peter
    I'm a computer science student, and I'm just starting to write relatively larger programs for my coursework (between 750 - 1500 lines). Up until now, it's been possible to get by with any reasonable level of modularization and object oriented design. However, now that I'm writing more complex code for my assignments I'd like to learn to write better code. Can anyone point me in the direction of some resources for learning about what sort of things to look for when designing your program's architecture so that you can make it as modularized as possible?

  • NHibernate: inserting additional calculated column

    - by Andrey Shchekin
    What would be your approach with NHibernate to do the following: When Comment is inserted into DB, and its property Text is inserted into column Text (due to a mapping), insert into column TextHash a hash of this property value. It seems trivial if I map TextHash, but how should I do this without mapping it? I do not need it in the domain model, its a DB-level optimization (I would use computed HashBytes if not for the length limit).

  • Node.js or Erlang

    - by gotts
    I really like these tools when it comes to the concurrency level it can handle. Erlang looks like much more stable solution but requires much more learning and a lot of diving into functional language paradigm. And it looks like Erlang makes it much better when it comes to multi cores CPUs(fix me if I'm wrong). But which should I choose? Which one is better in the short/long term perspective?

  • flex coverflow adding links to the images

    - by nivcaner
    Hi, I'm using sebastiaan holtrop's cover flow component in Flex. I would like to be able to add the sources to the images using xml. I would also like each image to have its own URL assosiated with it, so when I click it (if it's in the front of the coverflow), I go to that URL. I'm a bit clueless as to how to get that done (this is the first time I use Flex and the project docs think I'm a higher level Flex programmer...). Thanks, Niv

  • Tool to validate HTTP responses?

    - by Earlz
    Hello, I'm going to be messing with some stuff at the raw HTTP level during the next few days and I'd like to make sure I'm following the standard as close as possible. Are there any tools out there to validate the HTTP responses that my server puts out to make sure they conform to the specification?

  • What bugs apply to the different FindBugs reportLevels?

    - by Daniel H
    According to the Ant task, the report level is a low/medium/high setting that would look for bugs of different criticallity levels. However, there isn't anything I could find that explains which of the bugs apply to these different reporting levels. Is there somewhere that provides this, even if it is something I need to look at within the source?
