• What to name an array of flags?

  - by Chris

  I have a project where lots of the objects hold state by maintaining simple boolean flags. There are lots of these, so I maintain them within a uint32_t and use bit masking. There are now so many flags to keep track of, I've created an abstraction for them (just a class wrapping the uint32_t) with set(), clear(), etc. My question: What's a nice accurate, concise name for this class? What name could I give this class so that you'd have a reasonable idea what it was [for] knowing the name only? Some ideas I had: FlagBank FlagArray etc Any ideas? Thanks in advance! Cheers, -Chris

• size of view not changing after frame change

  - by MikeNelson

  I have managed to do pretty complex things on iPhone but I am always stuck with views, frames, bounds, and simple stuff that defies any logic and don't work as expected. I have a self.view in my code and it has a lot of subviews on it. At some point of the code, I need to reduce the frame vertically to a specific size and later put it back as before. Then I have this code: [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:1.5]; // frame is changing to a newHeight (other parameters are the same as before) self.view.frame = CGRectMake (0, 0, originalWidth, newHeight); [UIView commitAnimations]; The result is simply, nothing. The view continues as before. The same size, the same position. No change. Why this kind of thing happens? how to solve that?

• Struct in C, are they efficient?

  - by pygabriel

  I'm reading some C code like that: double function( int lena,double xa,double ya, double za, double *acoefs, ..., int lenb,double xb,double yb, double zb, double *bcoefs, ..., same for c, same for d ) This function is called in the code mor than 100.000 times so it's performance-critical. I'm trying to extend this code but I want to know if it's efficient or not (and how much this influences the speed) to encapsulate all the parameters in a struct like this struct PGTO { int len; double x,y,z ; double *acoefs } and then access the parameters in the function.

• where should we place HIDDEN variable in JSP

  - by micheal

  I need to use Hidden variables in my JSP for session tracking. this is the code: <input type="hidden" name="REQ_TOKEN" value="<%=session.getAttribute("SESN_TOKEN").toString()%>" /> i am using this to compare the request token with session token, so only when both are equal i will evaluate that request otherwise i will throw an error. Now the problem is, when i place this code inside <form></form> tags, it is working fine. Unfortunately there are some JSPs in my application where we dont have tag(I know that sounds weird!). where can i place my code so that it will work? Cant i use Hidden variables without FORM tag???

• SQLite.Net Issue With BeginTransaction

  - by cam

  I'm trying to use System.Data.Sqlite library, and I'm following the documentation about optimizing inserts so I copied this code directly out of the documentation: using (SQLiteTransaction mytransaction = myconnection.BeginTransaction()) { using (SQLiteCommand mycommand = new SQLiteCommand(myconnection)) { SQLiteParameter myparam = new SQLiteParameter(); int n; mycommand.CommandText = "INSERT INTO [MyTable] ([MyId]) VALUES(?)"; mycommand.Parameters.Add(myparam); for (n = 0; n < 100000; n ++) { myparam.Value = n + 1; mycommand.ExecuteNonQuery(); } } mytransaction.Commit(); } Now, I initialize I connection right before that by using SqlConnection myconnection = new SqlConnection("Data Source=blah"); I have a Database named blah, with the correct tables and values. The problem is when I run this code, it says "Operation is not valid due to the current state of the object" I've tried changing the code around several times, and it still points to BeginTransaction. What gives?

• Activator.CreateInstance fails in Windows Service

  - by kbe

  I have an issue with a Windows Service which throws a NullReference exception whenever I try to use var myType = Activator.CreateInstance(typeof(MyType)) There is no problem whenever I run the exact same code in a console window - and after debugging the obvious "which user is running this code" I doubt that it is a mere fact of changing the user running the service as I've tried to run the service using the computer's Administrator account as well as LocalSystem. I'm suspecting a Windows Update fiddling with default user rights but that's a bit of a desperate guess I feel. Remember: The type and assembly exist and works fine - otherwise I wouldn't be able to run the code in a console window. It is only when running in the context of a Windows Service I get an error. The question is: Can I in any way impersonate i.e. LocalSystem in a unittest by creating a GenericPrincipal (how would that GenericPrincipal look)?

• What's the fastest way to check the availability of a SQL Server server?

  - by mwolfe02

  I have an MS Access program in use in multiple locations. It connects to MS SQL Server tables, but the server name is different in each location. I am looking for the fastest way to test for the existence of a server. The code I am currently using looks like this: ShellWait "sc \\" & ServerName & " qdescription MSSQLSERVER > " & Qt(fn) FNum = FreeFile() Open fn For Input As #FNum Line Input #FNum, Result Close #FNum Kill fn If InStr(Result, "SUCCESS") Then ... ShellWait: executes a shell command and waits for it to finish Qt: wraps a string in double quotes fn: temporary filename variable I run the above code against a list of server names (of which only one is normally available). The code takes about one second if the server is available and takes about 8 seconds for each server that is unavailable. I'd like to get both of these lower, if possible, but especially the fail case as this one happens most often.

• WaitForSingleObject( )

  - by Rakesh Agarwal

  I have got myself stuck into a really amazing issue here.The code is like as below. class A { public: A(){ m_event = CreateEvent(NULL, false, false, NULL); // create an event with initial value as non-signalled m_thread = _beginthread(StaticThreadEntry, 0, this); // create a thread } static void StaticThreadEntry(A * obj) { obj->ThreadEntry(); } void ThreadEntry(); }; void A::ThreadEntry() { WaitforSingleObject(m_event,INFINITE); } int main() { A a; SetEvent(m_event); // sets the event to signalled state which causes the running thread to terminate WaitForSingleObject(m_thread, INFINITE); // waits for the thread to terminate return 0; } Problem : When the above code is run,sometimes( 1 out of 5 ) it hangs and the control gets stuck in the call to WaitforSingleObject()( inside the main function ).The code always calls SetEvent() function to ensure that the thread would terminate before calling Wait() function. I do not see any reason why it should ever hang?

• iPhone OSStatus -25308 or errSecInteractionNotAllowed SFHFKeychainUtils

  - by George Octavio

  Hi again guys. I'm trying to access my iPhone's device keychain. I want to access in order to create a simple user-password value intended for a log in function. This is the code I'm using from SFHFKeychainUtils NSArray *keys = [[[NSArray alloc] initWithObjects: (NSString *) kSecClass, kSecAttrService, kSecAttrLabel, kSecAttrAccount, kSecValueData, nil] autorelease]; NSArray *objects = [[[NSArray alloc] initWithObjects: (NSString *) kSecClassGenericPassword, serviceName, serviceName, @"TestUser", @"TestPass", nil] autorelease]; NSDictionary *query = [[[NSDictionary alloc] initWithObjects: objects forKeys: keys] autorelease]; OSStatus status = SecItemAdd((CFDictionaryRef) query, NULL); } else if (status != noErr) { //Output to screen with error code goes here return NO; } return YES; } The error code I'm getting is OSStatus-25308 or errSecInteractionNotAllowed. I'm guessing this means I don't actually have access to my iPhone's keychain? Is there a way to allow access? Thanks for your time.

• Cannot Debug Unmanaged Dll from C#

  - by JustSmith

  I have a DLL that was written in C++ and called from a C# application. The DLL is unmanaged code. If I copy the DLL and its .pdb files with a post build event to the C# app's debug execution dir I still can't hit any break points I put into the DLL code. The break point has a message attached to it saying that "no symbols have been loaded for this document". What else do I have to do to get the debugging in the dll source? I have "Tools-Options-Debugging-General-Enable only my code" Disabled. The DLL is being compiled with "Runtime tracking and disable optimizations (/ASSEMBLYDEBUG)" and Generate Debug Info to "Yes (/DEBUG)"

• javascript to launch only ONE window for a Java applet with a given URL

  - by Jonathan Dugan

  I need a javascript solution to launch only one window, with a Java Applet in it, for a given URL. I found a solution posted here on Stack Overflow - here: http://stackoverflow.com/questions/528671/javascript-window-open-only-if-the-window-does-not-already-exist But it doesn't seem to work .. I get Error: launchApplication.winrefs is undefined Line: 29 I can't seem to post the code in this little box and make it look right below, so the code (my working code, plus the solution from above) is here: http://pastie.org/833879 Where is the error? As I understand it, the hash or array or whatever I use to store the called references to the windows opened this way will be lost if the calling window is closed. Is there a way to make this work even if the calling window is closed and reopened? To basically ask the browser: "Do you have a window open with the following URL?" and if so, "What is the reference to that window?" (so I can raise it).

• Explanation for expires header

  - by sushil bharwani

  I have a joomla application working on Apache.To improve site performace we have written a .htaccess file to root of the application with setting a far future expires header to all the static content. As desired first time the files load in fresh with 200 status code. when again click on the same link many of the files are served directly from cache. I need explanation for two things When i press f5 then a number of files load with 304 status code however i expected them to be coming directly from cache without hitting the server for a status header? When i close the browser and come back to the same page again i see the same thing happening a number of files load with 304 status code although i thought they will load directly from the browser cache? I understand that 304 also servs file from browser cache but i want to avoid the header communication between servers as my static files wont ever change. Also i want to add that my requests are over a https connection does that create any issue.

• Have you been in cases where TDD increased development time?

  - by BillyONeal

  Hello everyone :) I was reading http://stackoverflow.com/questions/2512504/tdd-how-to-start-really-thinking-tdd and I noticed many of the answers indicate that tests + application should take less time than just writing the application. In my experience, this is not true. My problem though is that some 90% of the code I write has a TON of operating system calls. The time spent to actually mock these up takes much longer than just writing the code in the first place. Sometimes 4 or 5 times as long to write the test as to write the actual code. I'm curious if there are other developers in this kind of a scenario.

• How to convert raw_input() into a directory?

  - by Azeworai

  Hi everyone, I just picked up IronPython and I've been trying to get this IronPython script going but I'm stuck at trying to get a Path input from raw_input to be a directory path. The first block of code is the broken one that I'm working on. import System from System import * from System.IO import * from System.Diagnostics import * inputDirectory = raw_input("Enter Input Directory's full path [eg. c:\\vid\\]: ") print ("In: "+inputDirectory) outputDirectory = inputDirectory +"ipod\\" print ("Out: "+outputDirectory) #create the default output directory for s in DirectoryInfo(inputDirectory).GetFiles("*.avi"): print s.FullName arg = String.Format('-i "{0}" -t 1 -c 1 -o "{1}" --preset="iPod"' , s.FullName, outputDirectory + s.Name.Replace(".avi", ".mp4")) print arg proc = Process.Start("C:\\Program Files\\Handbrake\\HandBrakeCLI.exe", arg) #path to handbrake goes here proc.WaitForExit() The following code block is what I have working at the moment. import System from System import * from System.IO import * from System.Diagnostics import * for s in DirectoryInfo("F:\\Tomorrow\\").GetFiles("*.avi"): arg = String.Format('-i "{0}" -t 1 -c 1 -o "{1}" --preset="iPod"' , s.FullName, "F:\\Tomorrow\\ipod\\" + s.Name.Replace(".avi", ".mp4")) print arg proc = Process.Start("C:\\Program Files\\Handbrake\\HandBrakeCLI.exe", arg) #path to handbrake goes here proc.WaitForExit() PS: Credit for the above working code goes to Joseph at jcooney.net

• How do I get meaningful error messages in IIS7?

  - by Petras

  I have a classic ASP website that is crashing in IIS7. It is crashing because IIS doesn't allow file uploads greater than a certain size. I know this because files below about 200k work fine. I removed the Status Code 500 error in IIS but I still don't get a file name and the line where my code failed as I do when running locally. Instead I get: "The page cannot be displayed because an internal server error has occurred. If you are the system administrator please click here to find out more about this error." How do I get a file name and the line where my code failed? Here are my IIS settings:

• Using an IBAction method when it is not called from an action?

  - by cannyboy

  Are there any issues when using IBAction when it is not actually called from a user's action? If you have an action like -(IBAction)sayHello:(id)sender; You can call it from within your class like: [self sayHello:@"x"] The @"x" doesn't do anything, it just fills in for the sender. You can actually create an IBAction method without (id)sender -(IBAction)sayHello; and call it from both user's actions and from within the code, but then you won't get any useful sender info from the interface. What's the 'correct' way of filling in for the sender, when calling from the code? And can you create sender info to send when it's called from within the code? Just trying to figure it out.

• Cygwin bash syntax error - but script run perfectly well in Ubuntu

  - by Michael Mao

  #!/bin/bash if test "$#" == "4"; then echo "$*"; else echo "args-error" >&2; fi; This little code snippet troubles me a lot when I tried to run it on both Ubuntu and Cygwin. Ubuntu runs bash version 4.0+ whereas Cygwin runs 3.2.49; But I reckon version collision shall not be the cause of this, this code runs well under fedora 10 which is also using bash version 3.+ So basically I am wondering if there is a way to code my script once and for all so there are not to have this awful issue later on. Many thanks in advance.

• Why do my MIPS crosscompiler works like this for NOT operation?

And it compiles C code well. but I found a weird thing for NOT operations. if i make code like int a; func(!a); and i studied MIPS instructions with text book that says "MIPS converts NOT operation to 'nor with zero'" So i thought it would converted like nor a a $zero but my compiler converts xori a a 0x0 sltu a 1 /////////////////////////////////////// i compiled the code with 'myaccount mipsel-unknown-linux-gnu-gcc -S myfilename.c' and it makes myfilename.s file.. what am i missing??

• DynamicMethod NullReferenceException

I get a NullReferenceException. My DynamicMethod's signature is: public delegate void DynamicWrite(IMyXmlWriter writer, ref object value, MyContract contract); And I'm definitely not passing in anything null. Thanks in advance!

• Implement functionality in PHP?

  - by Rachel

  How can we Implement Bisect Python functionality in PHP Implement function bisect_left($arr, $item); as a pure-PHP routine to do a binary-bisection search for the position at which to insert $item into $list, maintaining the sort order therein. Assumptions: Assume that $arr is already sorted by whatever comparisons would be yielded by the stock PHP < operator, and that it's indexed on ints. The function should return an int, representing the index within the array at which $item would be inserted to maintain the order of the array. The returned index should be below any elements in $arr equal to $item, i.e., the insertion index should be "to the left" of anything equal to $item. Search routine should not be linear! That is, it should honor the name, and should attempt to find it by iteratively bisecting the list and comparing only around the midpoint.

• Is it possible to have a global exception hook?

  - by Heinrich Ulbricht

  Hi, my code is fairly well covered with exception handling (try..except). Some exceptions are not expected to happen and some exceptions happen fairly often, which is expected and ok. Now I want to add some automated tests for this code. It would be good to know how many exceptions happened during execution, so I can later see if the expected number was raised or anything unexpected happened. I don't want to clutter every exception handling block with debug code, so my question is: Is there a way to install some kind of global exception handler which sits right before all other exception handling blocks? I am searching for a central place to log these exceptions. Thanks for any suggestions! (And if this matters: it is Delphi 2009)

• is there a way to create an item template (t4) installer like the POCO generator?

  - by bryanjonker

  Subject says it all. I want to modify the POCO generation adapter (http://code.msdn.microsoft.com/EFPocoAdapter) to generate my own code. I have the .tt adapters done, but I want to be able to distribute this to coworkers, so they right-click on the model, choose "Generate Code", and my t4 templates appear in the options along with the other choices. Is there an easy way to do this? I found some articles at http://msdn.microsoft.com/en-us/library/tsyyf0yh(VS.80).aspx but it was focused on generic templates, and I'm looking for specifically model templates.

• Wanted: Command line HTML5 beautifier

  - by blinry

  Wanted A command line HTML5 beautifier running under Linux. Input Garbled, ugly HTML5 code. Possibly the result of multiple templates. You don't love it, it doesn't love you. Output Pure beauty. The code is nicely indented, has enough line breaks, cares for it's whitespace. Rather than viewing it in a webbrowser, you would like to display the code on your website directly. Suspects tidy does too much (heck, it alters my doctype!), and it doesn't work well with HTML5. Maybe there is a way to make it cooperate and not alter anything? vim does too little. It only indents. I want the program to add and remove line breaks, and to play with the whitespace inside of tags. DEAD OR ALIVE!
