• Processing SMTP bounces with .net

  - by justSteve

  Am looking for examples specific to .net/mvc and servers native WinServer08 where problem being addressed is processing a bounced smtp msg so as to bind to an estore transaction and updating account/profile properties. Reading the related questions i find an interesting reference to [VERP]2. Under the heading 'Software that supports VERP i find that IIS is not on the list. Does that mean i need to find a library to integrate into my store's assembly? What resources do I have to pull together to make sure that the webapp is informed when mail bounces? fwiw - i'm working with a very low volume site.

• console.log() and google chrome

  - by Lorenzo C

  I'm testing a library and I use console.log() function to visualyze values. There is a strange behaviour of Google Chrome (in other browser like Firefox it doesn't happend). If I try to store strings in Array object when I log them, sometimes values appears undefined. Code example (item.name is a string) var arrayItemsSearch = [item.name]; var itemRedrawName = [item.name]; console.log("arrayItemsSearch: ", arrayItemsSearch); console.log("itemRedrawName: ", itemRedrawName); Firefox output is correct arrayItemsSearch: ["elem[0]"] itemRedrawName: ["elem[0]"] Chrome output is not correct arrayItemsSearch: [undefined × 1] itemRedrawName: ["elem[0]"] Is this a Chrome bug? Or is this beacuse in Javascript strings are immutable objects and so something that I don't understand goes wrong?

• How to convert "9:00 PM EST" to a Date object

  - by Bara

  I am developing an Android application and require some basic datetime manipulation. I have a Date object (from Java.util.Date) holding a specific date. I need to add a specific time to it. The time I have is a string in this format: "9:00 PM EST" How would I "add" this time to the previous date? If the Date object currently has: "4/24/10 00:00:00" How would I change it to instead be: "4/24/10 09:00:00 EST" I would prefer to do this without the use of an external library, if possible.

• boost timer usage question

  - by stefita

  I have a really simple question, yet I can't find an answer for it. I guess I am missing something in the usage of the boost timer.hpp. Here is my code, that unfortunately gives me an error message: include <boost/timer.hpp> int main() { boost::timer t; } And the error messages are as follows: /usr/include/boost/timer.hpp: In member function ‘double boost::timer::elapsed_max() const’: /usr/include/boost/timer.hpp:59: error: ‘numeric_limits’ is not a member of ‘std’ /usr/include/boost/timer.hpp:59: error: ‘::max’ has not been declared /usr/include/boost/timer.hpp:59: error: expected primary-expression before ‘double’ /usr/include/boost/timer.hpp:59: error: expected `)' before ‘double’ The used library is boost 1.36 (SUSE 11.1). Thanks in advance!

• Blob ID matching over multiple frames in C++ (image analysis)

  - by pollux

  Dear reader, I'm working on a blob matching and tracking library in C++. Currently I'm using openCV to detect blobs and try to match blobs in a new frame by checking the position, velocity and size of the blob. This works quite okay and I'm receiving a high blob match rate (95% or higher). Sometimes blobs fall out of the image or new blobs appear. Now I need to give matched blobs the same ID as they had before. I'm wondering if there are typical or commonly used techniques for doing this. Or even some keywords I can use to google on. Thanks

• Does the XML specification states that parser need to convert \n\r to \n always, even when \n\r appe

  - by mic.sca

  Hi, I've stumbled in a problem handling the \line-feed and \carriage-return characters in xml. I know that, according to http://www.w3.org/TR/REC-xml/#sec-line-ends, xml processors are required to replace any "\n\r" or lone "\r" sequences with "\n". The specification states that this has to be the behaviour for handling any "external parsed entity", does this apply to CDATA sections inside of an element as well? thank you, Michele I'm sure that msxml library for example converts every \n\r" or lone "\r" sequences to "\n", regardless of their being in a cdata section or not.

• Objective C: Why is this code leaking?

  - by Johnny Grass

  I'm trying to implement a method similar to what mytunescontroller uses to check if it has been added to the app's login items. This code compiles without warnings but if I run the leaks performance tool I get the following leaks: Leaked Object # Address Size Responsible Library Responsible Frame NSURL 7 < multiple > 448 LaunchServices LSSharedFileListItemGetFSRef NSCFString 6 < multiple > 432 LaunchServices LSSharedFileListItemGetFSRef Here is the responsible culprit: - (BOOL)isAppStartingOnLogin { LSSharedFileListRef loginListRef = LSSharedFileListCreate(NULL, kLSSharedFileListSessionLoginItems, NULL); if (loginListRef) { NSArray *loginItemsArray = (NSArray *)LSSharedFileListCopySnapshot(loginListRef, NULL); NSURL *itemURL; for (id itemRef in loginItemsArray) { if (LSSharedFileListItemResolve((LSSharedFileListItemRef)itemRef, 0, (CFURLRef *) &itemURL, NULL) == noErr) { if ([[itemURL path] hasPrefix:[[NSBundle mainBundle] bundlePath]]) { [loginItemsArray release]; CFRelease(loginListRef); return YES; } } } [loginItemsArray release]; CFRelease(loginListRef); } return NO; }

• How do you handle multiple (overlapping) projects in trac?

  - by Oliver Giesen

  We are using trac and are really satisfied with it. However, out of the box, trac is best suited for single-project environments only. I'd be interested to hear about the various approaches people take to make it work with multiple projects nevertheless and their experiences with them. Are there any plugins to recommend? Any patches, tweaks or whatnots? Are you maybe even using an entirely different bug-tracking system that offers all of trac's functionality plus multi-project support? We recently started managing a second project ourselves which generally works okay but also has some drawbacks, especially where the two projects overlap because of common library code we wrote that is used in both projects. How do you handle this? (I'll attach our own current approach as an answer to this post.)

• Combining several static archives into a new one

  - by knight666

  I'm making a game engine for mobile devices. I want to compile my code, link it against a few static libraries and then combine my compiled code with those static libraries to form a new static library. However, my Google Fu is abandoning me. Suppose I have static libraries a.a, b.a and c.a and my code. I want to compile all that into awesome.a. How can I do that? I'm using CodeSourcery's arm-none-linux-gnueabi-ar by the way. Thanks in advance.

• Tools for displaying text, powerpoint style, in linux

  - by Will Mc

  I have a problem where I need a way to display a repeating series of "images" on a computer monitor. Specifically, given a series of text files, I'd like a way to display the contents of said files on a screen in a way much like a powerpoint would. My current thoughts are to find some tool that will take in a text file of some format, and then output an image which contains the text from the file. Then I'd put it in a directory and have some Slideshow program continuously go between the images in that directory. It's a very hacky solution, obviously. So, does anyone know of tools that would do such a thing? Or is there a better way to do this? I've looked into the library libgd2, but it doesn't seem to support text-wrapping for images, which is something I'd need. Thanks!

• Android sending SOAP object over Https via ksoap2 2.5.8

  - by Jack-V

  My first time posting a question here so please do not mind my mistakes here. I'm currently making an android application fetching and sending information from a .asmx web service. Everything goes well with the ksoap2 library and am using HttpTransportSE to call the web service. So now what I'm trying to do is to use the HttpsTransportSE to call the web service over Https. I got java.security.cert.certpathvalidatorexception trustanchor for certpath not found exception. I have the server certificate in .pfx , .jks and .bks format. My questions is what do i do with it to make my HttpsTransportSE call to be success? I've read around with articles using custom SSLSocketFactory but am still not sure how to implement it in my application. Thanks in advance for any suggestion/advices

• PHP/Codeigniter FTP Timout

  - by Jack Hayter

  I'm trying to access an FTP server from my PHP script using Codeigniter's FTP Library. These functions work great, but when testing the script I discovered that if I attempt to connect to a server that does not exist, the script does not terminate with an error message of any kind. The page continues to execute, until the web server gives up, returning an empty document. So I am wondering, is there a way to limit the amount of time that Codeigniter can try to connect to an FTP server, then display a message if that times out? I tried using the php function set_time_limit(), but it does not behave how I expected it to. Thanks for your help.

• What SQL ORM may i use to replace this old code

  - by acidzombie24

  Sorry since this question is specific to my problem. While learning reflections i did a mini SQL ORM in a week then minor tweaks while using it for another week. Since it has very little work put into it, its really only compatibility with sqlite. I havent had problems with the code so far but i would like to port it to something that supports TSQL or MySql. The example code is here which is outdated but has the most used functions in my class. What library can i port that code over too with the smallest about of pain. Note that it must support foreign keys.

• Is there a way of providing a final transform method when chaining operations (like map reduce) in underscore.js?

  - by latentflip

  (Really strugging to title this question, so if anyone has suggestions feel free.) Say I wanted to do an operation like: take an array [1,2,3] multiply each element by 2 (map): [2,4,6] add the elements together (reduce): 12 multiply the result by 10: 120 I can do this pretty cleanly in underscore using chaining, like so: arr = [1,2,3] map = (el) -> 2*el reduce = (s,n) -> s+n out = (r) -> 10*r reduced = _.chain(arr).map(map).reduce(reduce).value() result = out(reduced) However, it would be even nicer if I could chain the 'out' method too, like this: result = _.chain(arr).map(map).reduce(reduce).out(out).value() Now this would be a fairly simple addition to a library like underscore. But my questions are: Does this 'out' method have a name in functional programming? Does this already exist in underscore (tap comes close, but not quite).

• Getting every nth Element of a Sequence

  - by Alexander Rautenberg

  I am looking for a way to create a sequence consisting of every nth element of another sequence, but don't seem to find a way to do that in an elegant way. I can of course hack something, but I wonder if there is a library function that I'm not seeing. The sequence functions whose names end in -i seem to be quite good for the purpose of figuring out when an element is the nth one or (multiple of n)th one, but I can only see iteri and mapi, none of which really lends itself to the task. Example: let someseq = [1;2;3;4;5;6] let partial = Seq.magicfunction 3 someseq Then partial should be [3;6]. Is there anything like it out there? Edit: If I am not quite as ambitious and allow for the n to be constant/known, then I've just found that the following should work: let rec thirds lst = match lst with | (_,_,x)::t -> x::thirds t | _ -> [] Would there be a way to write this shorter?

• CRT not initialized

  - by jfhs

  I'm trying to compile one project with MSVC 2010, compilation is ok, but when I try to run the app, it gives me CRT not initialized error. It is a console application, so I tried to specify mainCRTStartup as Entry Point, but it didn't help. In the same solution there are other projects, and they don't have such a problem. The difference which I see between them is that one which is not working, uses boost. Boost v1.38.0 if this is important. Runtime Library is Multi-threaded DLL. Linker command line is: /OUT:"D:\temp\ghost\Release\ghost.exe" /INCREMENTAL:NO /NOLOGO /LIBPATH:"..\zlib\lib" /LIBPATH:"..\mysql\lib\opt" /LIBPATH:"..\boost\lib" "ws2_32.lib" "winmm.lib" "zdll.lib" "StormLibRAS.lib" "kernel32.lib" "user32.lib" "gdi32.lib" "winspool.lib" "comdlg32.lib" "advapi32.lib" "shell32.lib" "ole32.lib" "oleaut32.lib" "uuid.lib" "odbc32.lib" "odbccp32.lib" "D:\temp\ghost\bncsutil\vc8_build\Release\BNCSutil.lib" /MANIFEST /ManifestFile:"Release\ghost.exe.intermediate.manifest" /ALLOWISOLATION /MANIFESTUAC:"level='asInvoker' uiAccess='false'" /DEBUG /PDB:"D:\temp\ghost\Release\ghost.pdb" /SUBSYSTEM:CONSOLE /OPT:REF /OPT:ICF /PGD:"D:\temp\ghost\Release\ghost.pgd" /LTCG /TLBID:1 /ENTRY:"mainCRTStartup" /DYNAMICBASE /NXCOMPAT /MACHINE:X86 /ERRORREPORT:QUEUE

• Should I use a modified singleton design pattern that only allows one reference to its instance?

  - by Graham

  Hi, I have a class that would normally just generate factory objects, however this class should only used once throughout the program in once specifix place. What is the best design pattern to use in this instance? I throught that having a modified singleton design which only allows one reference to instance throughout the program would be the correct way to go. So only the first call to getInstance() returns the factory library. Is this a good or bad idea? Have I missed out another fundermental design pattern for solving this problem? Thanks for your help.

• Unable to link to opengl libraries? DOS / MSVC

  - by Mark

  Is there something wrong with this link.exe command line? OpenGL32.lib and Glu32.lib are found at both of the LIBPATH directories. Is it possible the libraries are somehow incompatible? Is there a way to have the link.exe say that instead of unresolved external symbol? Googling shows that this error usually means the libraries are not found, but they are there.

• How to write a tool, inverting colors in Windows?

  - by vlood

  I read a topic in this site about it, but decided to post another one as I want to write such a tool, but I don't have much experience in C# & .NET, so it could take me too much time just digging the Net, while someone can just direct me to the right library or classes to be used. So, straight to the point. I want to write a tool that, when activated, inverts absolutely all items on the screen and lets you work that way without torturing your eyes with bright light colors. Does anyone have an idea of the needed .NET libraries or third-party frameworks, to implement this? Any help will be greatly appreciated! P.S. Changing to "High Contrast" theme in Windows is not the solution I seek, so please, don't mention it!

• facebook api getting full posts with > 2 comments or > 4 likes

  - by ejang

  when I make the user/feed request on the Facebook Open Graph API, I get a feed object where posts with 2 comments or 4 likes don't reveal the detailed information for those specific comments. I am using https://github.com/Thuzi/facebook-node-sdk to make requests but it is very similar to the 'request' NodeJS library. I can get the full posts individually by making a separate request for that post's Open Graph ID, but this doesn't lend itself to fun code because requests are asynchronous and nesting more asynchronous calls within asynchronous calls doesn't lend itself to fun code. Any way I can obtain the full posts?

• Why do Java and C# not have implicit conversions to boolean?

  - by Shaun

  Since I started Java it's been very aggravating for me that it doesn't support implicit conversions from numeric types to booleans, so you can't do things like: if (flags & 0x80) { ... } instead you have to go through this lunacy: if ((flags & 0x80) != 0) { ... } It's the same with null and objects. Every other C-like language I know including JavaScript allows it, so I thought Java was just moronic, but I've just discovered that C# is the same (at least for numbers, don't know about null/objects): http://msdn.microsoft.com/en-us/library/c8f5xwh7(VS.71).aspx Microsoft changed it on purpose from C++, so why? Clearly I'm missing something. Why change (what I thought was) the most natural thing in the world to make it longer to type? What on Earth is wrong with it?

• Do mini-filter functions need APCs enabled?

  - by botismarius

  Hello, Many Zw* functions that work with files (such as ZwCreateFile) need to be called at PASSIVE_LEVEL with APCs enabled: http://msdn.microsoft.com/en-us/library/ff566424%28VS.85%29.aspx. This is because, internally, I/O operations are asynchronously and the completion of an operation is delivered through an APC (correct me if I'm wrong). However, the documentation for similar functions from a mini-filter (such as FltCreateFile, FltReadFile, etc) does not specify that APCs should be enabled. Is it safe to call FltCreateFile/FltReadFile with APCs disabled? Thanks!

• How determine application subsystem from executable file

  - by Luca

  I'm trying to detect console application from the list of the executables files installed on my computer. How to implement it? Every application has a "subsystem" (windows application, console application or library; specified to the linker as option, I think). How to detect it using only the executable file? Are there alternative methods to detect the application characteristic? Additionally, are there any method for detecting the file is a really executable file? Any issue for JAR executables?

• Avoid stuck calling callback

  - by andlomba

  Hello all, This is a question about generic c++ event driven applications design. Lets assume that we have two threads, a "Dispatcher" (or "Engine"...) and a "Listener" (or "Client"...). Let's assume that I write the Dispatcher code, and release it as a library. I also write the Listener interface, of course. When the Dispatcher executes (after Listener registration) listenerInstance.onSomeEvent(); the event handling code will actually be executed by the Dispatcher thread, so if the person that implements the Listener writes something like void Listener::onSomeEvent() { while(true) ; } The Dispatcher will stuck forever. Is there a "plain old c++" (I mean no boost or libsigc++) way to "decouple" the two classes, so I can be sure that my Dispatcher will work fine whatever the Listeners does in the callbacks? bye and thanks in advance, Andrea

  Hi I m working on online video conferencing project in c# and .Net4.0 I want a library or code which i can used for collecting web camera inges per second in diferent form. I try this by using the AVICAP32, in which we send Messages for diferent purpose like copy or edit frames.but in this we have to pass a reference of picturebox while creating handler as given below mCapHwnd = capCreateCaptureWindowA("0", 268435456 | 1073741824, 0, 0, 640, 480,picturebox1.Handle.ToInt32(), 0); usiing these commands i m able to capture images but the problem comes when i minimize the picturebox form . at that time doesn't create new image . I think this is happened because i minimize the form and when it copy the image from this clipboard it doesn't shhow anything. How can i solve this problem . Any type of help will be appreciated. Thanks srdusad
