• Handling messages for window from other process

  - by MK

  I'm developing a C# WPF application that reparents the main window of another application using a call to Win32 SetParent(). The handle to this out-of-process child window is wrapped by a class named FormHost which is derived from HwndHost. All is working well except for one thing: messages for the reparented window are not delivered to FormHost. MSDN documentation clearly states that the HwndHost window procedure WndProc() cannot be used with out-of-process windows. The alternative, MessageHook doesn't work either. I also tried calling AttachThreadInput() to combine the input processing of the two windows. No luck. Any suggestions?

• SWIG generated code fails to run on PHP 5.3.2 undefined symbol: zend_error_noreturn

  - by wookiebreath

  I have a library that I have been using successfully with PHP 5.1.6 with the help of some wrapper code generated by SWIG (v1.3.40). I have just upgraded to PHP 5.3.2 and I am seeing the following error: PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php/modules/myLib_php.so' - /usr/lib/php/modules/myLib_php.so: undefined symbol: zend_error_noreturn in Unknown on line 0 On investigation it appears that the wrapper code produced by SWIG (myLib_wrap.c) includes calls to the PHP function: zend_error_noreturn and that this function isn't available in PHP 5.3.2? Has anyone seen this issue before? Things seem to work if I manually update the generated code so that instead of calling zend_error_noreturn it just calls zend_error. Is this approach safe?

• Packaging a Bundle with a static library

  - by 4thSpace

  I have a static library that includes some xibs. These will basically be the same across projects. I'd like to include the xibs as part of the library. I can include their veiwcontrollers, reference these controllers in the calling project but then there isn't a xib to load. When I right click the xib in the library project, it can't be part of the target. I thought about creating a CFPluginBundle but that creates a new project. I'd loose all of my IBOutlet and IBAction references. What is the best way to reuse xibs that also have outlets and actions to specific controllers?

• Authentication on odata service

  - by Toad

  I want to add some authentication to my odata service. Depending on the user calling i want to: filter rows and/or remove columns. I read in scott hanselmans fine blogpost on odata ( http://www.hanselman.com/blog/CreatingAnODataAPIForStackOverflowIncludingXMLAndJSONIn30Minutes.aspx )that it is possible to intercept the incoming queries. If this works i could add some extra filtering. How would this intercepting and altering queries work exactly? I can not find any examples of where and how to do this. (i'm using entitie framework and wcf dataservices (just like scotts example blog)

• Rogue black-box java application not responding to standard input redirect

  - by Stefan Kendall

  I have an external java application (blackbox), which requires authentication. I need to run this application in a batch setting, but it seems to be reading from standard input in some nonstandard way. That is, if I set the calling of the program to redirect STDIN to a file (... <password.txt) or pipe data to it (echo mypasword | ...), it does not recognize the input. As I run it, also, it seems to intercept Cntrl+c and Cntrl+d and Cntrl+z as legitimate password characters, so it must be doing something odd and not just reading from standard in. Any idea what this application could be doing to read in input? I need to be able to send it information programmatically, and I'm stumped for the moment.

• rails - named scoped help

  - by sameera207

  Hi All, I want to write a named scoped to get a record from its id. Ex: I have a model called Event and its same as doing Event.find(id) (I dont want to use find inside my controller and I want my controller to use a named scoped (for future flexibility)) So I have written a named scoped named_scope :from_id, lambda { |id| {:conditions = ['id= ?', id] } } and I'm calling it from my controller like Event.from_id(id) But my problems is it returns Event object array not only one object Ex: if I want to get event name I have to write event = Event.from_id(id) event[0].name instead I want to write event = Event.from_id(id) event.name Am I doing something wrong here.. thanks in advance cheers sameera

• Java Timers - Functions called not completing!

  - by Matt Swanson

  So I have a TimerTask task calling a function onTimerComplete() in its run() onTimerComplete() looks something like this: private void onTimerComplete(){ myFunc1(); myFunc2(); } I make a Timer t and I schedule the TimerTask with t.schedule(task, 2000); The problem is, when the timer is up and the task runs my onTimerComplete() but that function does not finish. It runs myFunc1() but never finishes it nor does it ever call myFunc2() However, if I call onTimerComplete() directly, everything works. What's the deal here?

• How does delete deal with pointer constness?

  - by aJ

  I was reading this question Deleting a const pointer and wanted to know more about delete behavior. Now, as per my understanding: delete expression works in two steps: invoke destructor then releases the memory (often with a call to free()) by calling operator delete. operator delete accepts a void*. As part of a test program I overloaded operator delete and found that operator delete doesn't accept const pointer. Since operator delete does not accept const pointer and delete internally calls operator delete, how does Deleting a const pointer work ? Does delete uses const_cast internally?

• Embed a Python persistance layer into a C++ application - good idea?

  - by Rickard

  say I'm about to write an application with a thin GUI layer, a really fat calculation layer (doing computationally heavy calibrations and other long-running stuff) and fairly simple persistance layer. I'm looking at building the GUI + calculation layer in C++ (using Qt for the gui parts). Now - would it be a crazy idea to build the persistance layer in Python, using sqlalchemy, and embed it into the C++ application, letting the layers interface with eachother through lightweigth data transfer objects (written in C++ but accessible from python)? (the other alternative I'm leaning towards would probably be to write the app in Python from the start, using the PyQt wrapper, and then calling into C++ for the computational tasks) Thanks, Rickard

• Complex String Processing - well complex to me

  - by percent20

  I am calling a web service and all I get back is a giant blob of text. I am left to process it myself. Problem is not all lines are necessarily the same. They each have 2 or 3 sections to them and they are similar. Here are the most common examples text1 [text2] /text3/ text1/test3 text1[text2]/text3 text1 [text2] /text /3 here/ I am not exactly sure how to approach this problem. I am not too good at doing anything advanced as far as manipulating strings. I was thinking using a regular expression might work, but not too sure on that either. If I can get each of these 3 sections broken up it is easier from there to do the rest. its just there doesn't seem to be any uniformity to the main 3 sections that I know how to work with.

• Read and write from a byte stream if the endianess of the data is different from that of the current

  - by Sam Holder

  I have a stream of bytes which contains a flag which identifies the endianness of the data in the header. I want to read the doubles from the stream, which will presumably need to be different if the endianness of the data in the header is different? I am currently using a BinaryReader and calling ReadDouble to read the data from the stream, but if the endianness flag indicates that the data stream has a different endianness than the machine architecture then presumably this will not work? How should this be handled? Should I check the endianness of my data against that of the current machine then when I want to read a double instead read the bytes raw into a byte array and do array.Reverse to reverse the data before using BitConverter.ToDouble () with the reversed data and a zero offset? I could just test this but I do not have a source of data for both endianness so am a bit concerned about creating test data to test the parsing and this being different from what 'real' data might look like.

• What should I use for the filepath if I'm developing from my desktop?

  - by codeninja

  I'm having an extremely difficulty time getting the flowplayer to show up and the worst part is I have no idea what is wrong because I'm not getting any error messages! I have an external javascript file: C:/desktop/mysite/js/jq/plugins.js calling $f() from: C:/desktop/mysite/thirdparty/flowplayer/flowplayer.js the swf files also live there... I'm working on file/desktop (no localhost or webserver) $(video.id).flowplayer("thirdparty/flowplayer/flowplayer-3.1.15.swf", { clip:{ .... }, // min Flash version version:[9,115], // older versions will see a custom message onFail:function(){ alert("Failed!"); }, onError:function(errCode,errMsg){ alert(errCode+errMsg); } }); I don't know what path to use for the SWFs to get them to load, is the path relative to the javascript (plugins.js) that calls $f() or is it relative to the path of the flowplayer.js ?? bangs head on wall

• get the response of a jquery ajax call as an input parameter of another function:

  - by Nauman Bashir

  Hello, Is it possible to make a jquery ajax call, and get the response as an input parameter of another function: here is an example, i have the following function call at a location: updateTips(validationTextObject,objUsers.fetchAvailable()); the objUsers.fetchAvailable() function makes a ajax call to the server. The callback function on successful call would be something like this. It is being used to process the result BHUsers.prototype.recvAvailable= function(response){ // some kind of processing over here return (response["status"] == "OK")? "Available" : "Not Available"; } I want that fuction to return the processed result which can be used as a parameter to the function updateTips The primary goal of this is to be able to do all of this for multiple scenarios, rather than writing multiple functions for the same call. Also i want the calling and the response processing functions to just do what they are doing. I dont want to add html objects into it. Any Clues?

• JPA Cascade delete.

  - by Win Man

  Hi, I am new to JPA/Hibernate. Currently using EJB3, Hibernate/JPA. I have an inheritacnce structure as follows.. @Entity @DiscriminatorColumn(name = "form_type") @Inheritance(strategy = InheritanceType.JOINED) @GenericGenerator(name = "FORMS_SEQ", strategy = "sequence-identity", parameters = @Parameter(name = "sequence", value = "FORMS_SEQ")) @Table(name = "Forms") public abstract class Form{ //code for Form } @Entity @Table(name = "CREDIT_CARDS") @PrimaryKeyJoinColumn(name="CREDIT_CARD_ID") public class CreditCardForm extends Form { //Code for CreditCards. } When I add a row with save the rows are properly inserted into the parent and the child table. However when I try to delete I get an error - 10:19:35,465 ERROR [TxPolicy] javax.ejb.EJBTransactionRolledbackException: Removing a detached instance com.data.entities.form.financial.CreditCard#159? I am using a simple for loop to determine the inheritance type - CreditCard or DebitCard and then calling entityManager.remove(entity). What am I doing wrong? Code for delete.. for(Form content: contents){ if(content.getType()==Type.CREDIT_CARD){ creditCardService.delete((CreditCard)content); } Thanks. WM

• Why does MSBuild fail from the command line where VS2008 succeeds?

  - by sundeep

  I have an ASP.NET solution that builds just fine from within VS2008. However , it fails when i do this : MSBUILD.exe c:\path-to-sln It fails with a CS0006 error ("Metadata file 'dll_name' could not be found"). It also fails when I try with a .csproj of a project within the solution. What is VS2008 doing that MSBuild is missing ? It is my understanding that VS knows about inter assembly dependencies that MSBuild cant. Is there any way I can inform MSBuild of these? (I need MSBuild to work from the command line because I am calling it from an MSBuild-Task from within CruiseControl.Net.) Thanks in Advance. :3) (I have looked at http://stackoverflow.com/questions/280559/how-to-get-cmd-line-build-command-for-vs-solution , but still dont get it)

• Run a PHP-script from a PHP-script without blocking

  - by Nicklas Ansman

  I'm building a spider which will traverse various sites and data mining them. Since I need to get each page separately this could take a VERY long time (maybe 100 pages). I've already set the set_time_limit to be 2 minutes per page but it seems like apache will kill the script after 5 minutes no matter. This isn't usually a problem since this will run from cron or something similar which does not have this time limit. However I would also like the admins to be able to start a fetch manually via a HTTP-interface. It is not important that apache is kept alive for the full duration, I'm, going to use AJAX to trigger a fetch and check back once in a while with AJAX. My problem is how to start the fetch from within a PHP-script without the fetch being terminated when the script calling it dies. Maybe I could use system('script.php &') but I'm not sure it will do the trick. Any other ideas?

• PHP Array to String equivalent

  - by Matt

  Hey all, I'm wondering if anyone has a recursive solution to converting an array to a string. Here's what I mean: An array $args that has the following contents: Array ( [0] => $hello [1] => 411px [Jeeves] => Array ( [compiling] => 1 ) ) Result after calling arr_to_string($args): array($hello,"411px", "Jeeves" => array("compiling" => 1)); Note: It recognizes the $ sign in front and therefore does not add quotes. It does the same for numbers. Anyone have any solution or can point me in the right direction? Thanks! Matt Mueller

• capture any error in VBScript?

  - by JoelFan

  I have a batch file that calls a VBScript (.vbs) program. After calling it, my batch script checks errorlevel to see if the .vbs program failed. I can signal failure with an exit code in the .vbs program with WScript.Quit(1). However, I can only do that explicitly. If some unexpected run-time error happens, the .vbs quits with an error dialog box, however the exit code is zero so my batch file thinks it suceeded! How can I change that behavior? And if you are thinking of saying, use on error goto, don't bother... that syntax is available in regular VB, but not in VBScript.

• Using fscanf with dynamically allocated buffer.

  - by ryyst

  Hi, I got the following code: char buffer[2047]; int charsRead; do { if(fscanf(file, "%2047[^\n]%n%*c", buffer, &charsRead) == 1) { // Do something } } while (charsRead == 2047); I wanted to convert this code to use dynamically allocated variables so that when calling this code often I won't get heavy memory leakage. Thus, I tried this: char *buffer = malloc(sizeof(char) * 2047); int *charsRead = malloc(sizeof(int)); do { if(fscanf(file, "%2047[^\n]%n%*c", *buffer, charsRead) == 1) { // Do something } } while (*charsRead == 2047); Unfortunately, this does not work. I always get “EXC_BAD_ACCESS” errors, just before the if-statement with the fscanf call. What am I doing wrong? Thanks for any help! -- Ry

• Racket: change dotted pair to list

  - by user2963128

  I have a program that recursively calls a hashtable and prints out data from it. Unfortunately my hashtable seems to be saving data as dotted pairs so when I call the hashtable I get an error saying that there is no data for it because its tryign to search the hashtable for a dotted pair instead of a list. Is there an easy way to make the dotted pair into a regular list? IE im getting '("was" . "beginning") instead of '("was" "beginning") Is there a way to change this without re-writing how my hashtable store stuff? im using the let function to set a variable to this and then calling another function based on this variable (let ((data ( list-ref(hash-ref Ngram-table key) (random (length (hash-ref Ngram-table key)))))) is there a way to make the value stored in data just a list like this '("var1" "var2") instead of a dotted pair? edit: im getting dotted pairs because im using let to set data to the part of the hashtable's key and one of the elements in that hash.

• How to Use an Environment Variable as an Environment Variable Name

  - by Synetech inc.

  Hi, In my pursuit of a solution to another environment-variable/batch-file related problem, I have once again come across a problem I have visited before (but cannot for the life of me remember how, or even if I solved it). Say you have two BAT files (or one batch file and the command line). How can one pass an environment variable name to the other so that it can read the variable? The following example does not work: A.BAT: @call b.bat path B.BAT: @echo %%1% > A.BAT > %1 > B.BAT path > %1 It is easy enough to pass the environment variable name, but the callee cannot seem to use it. (I don’t remember if or how I dealt with this the last time it came up, but I suspect it required the less-than-ideal use of redirecting temporary BAT files and calling them and such.) Any ideas? Thanks.
