• Function for getting localized path?

  - by MartinStettner

  Windows 7 (and probably Windows Vista) display localized folder names using the LocalizedResourceName entry in the desktop.ini file. For my Documents folder, this looks like [.ShellClassInfo] LocalizedResourceName=@%SystemRoot%\system32\shell32.dll,-21770 IconResource=%SystemRoot%\system32\imageres.dll,-112 IconFile=%SystemRoot%\system32\shell32.dll IconIndex=-235 (see this question) This way the explorer displays the path "C:\Users\Username\Documents" as "C:\Benutzer\Username\Dokumente" on a german Windows. I wonder, if there's any build-in shell function to automatically get this localized name or, even better, transform a whole path into its localized form (best would be anything in .NET)? This is even more interesting as the LocalizedResourceName entry is only documented for Windows CE (see here). Thanks Martin

  This code is present in one of this activity. I want to restrict addJoke() function from executing if the String variable new_joke is null, has no text or contains just spaces.

• Which one is better to have auto-implemented property with private setter or private field and property just getter?

  - by PLB

  My question may be a part of an old topic - "properties vs fields". I have situation where variable is read-only for outside class but needs to modified inside a class. I can approach it in 2 ways: First: private Type m_Field; public Type MyProperty { get { return m_Field; } } Second: public Type MyProperty { get; private set; } After reading several articles (that mostly covered benefits of using public properties instead of public fields) I did not get idea if the second method has some advantage over the first one but writing less code. I am interested which one will be better practice to use in projects (and why) or it's just a personal choice. Maybe this question does not belong to SO so I apologize in advance.

• Getting instance of a class in ArrayList

  - by user1499974

  I have a small problem with ArrayList. You see, I wish to get an instance of RenderNewHUD in my renderer class, which has a list of registered renderers. I did not want to create a variable for this due to limitations and awkwardness. Here is my code. RenderNewHUD hud = renderer.renderList.get(RenderNewHUD()); How exactly can I go along getting the instance of RenderNewHUD without creating a new instance? If you need any more of my code, just ask. Sorry if this is a very dumb question - I have looked EVERYWHERE for an answer.

• Format decimal to currency, should be in cents for values $0 to $1

  - by Spongeboy

  I have a decimal variable which represents a donation amount. Currently I am displaying it on screen as a currency like so- DonationAmount.ToString("C"); This gives the following output (given a US locale) 1 -> $1.00 2 -> $2.00 0.5 -> $0.50 I am happy with the first two example, but want to have "0.5" show as "50c". My current solution is with a conditional- if (DonationAmount > 1) return (DonationAmount * 100m).ToString() + "c"; else return DonationAmount.ToString("C"); Is there a better way?

• Error : The Type Initializer of Daemon.Global threw an exception in c#

  - by srk

  I am using the below class file, where some variables are declared to use in the entire application. Now I used that variable BlockLogOut in another class file to make the value true. I just put this below line and getting error in it.. TypeInitializationException Global.BlockLogOut = True; The weird thing is, it was working fine for many months and i am getting this error now on the above line. Of course i was modifying some other stuffs in the application, but surely not this class file. What would have been the problem? namespace Daemon { class Global { public static bool BlockLogOut = false; } }

• Cast vector<T> to vector<const T>

  - by user345386

  I have a member variable of type vector (where is T is a custom class, but it could be int as well.) I have a function from which I want to return a pointer to this vector, but I don't want the caller to be able to change the vector or it's items. So I want the return type to be const vector* None of the casting methods I tried worked. The compiler keeps complaining that T is not compatible with const T. Here's some code that demonstrates the gist of what I'm trying to do; vector<int> a; const vector<const int>* b = (const vector<const int>* ) (&a); This code doesn't compile for me. Thanks in advance!

• How do include paths work in Visual Studio?

  - by Paperflyer

  Visual Studio drives me crazy and I am suspecting I am doing something wrong. This is what I do: I installed Visual Studio (Pro '08) a long time ago, I installed the Windows SDK (Win 7 x64), someone emails me a project, it fails to build. Invariably, it can not find windows.h. While it is easy enough to include C:\Program Files\Microsoft SDKs\Windows\v7.0\Include in the project settings of every single project, I feel that this may not be the proper way to do it. Is there a way to somehow make Visual Studio globally aware of these files? I also tried to include the above directory in the path variable but that didn't change anything. Also, it will randomly find windows.h but not winresrc.h in the same directory.

• Database table schema design - varchar(n). Suitable choice of N

  - by morpheous

  Coming from a C background, I may be getting too anal about this and worrying unnecessarily about bits and bytes here. Still, I cant help thinking how the data is actually stored and that if I choose an N which is easily factorizable into a power of 2, the database will be more effecient in how it packs data etc. Using this "logic", I have a string field in a table which is a variable length up to 21 chars. I am tempted to use 32 instead of 21, for the reason given above - however now I am thinking that I am wasting disk space because there will be space allocated for 11 extra chars that are guaranteed to be never used. Since I envisage storing several tens of thousands of rows a day, it all adds up. Question: Mindful of all of the above, Should I declare varchar(21) or varchar(32) and why?

• best way to write a-> ..->[a] recursive functions in haskell

  - by Roman A. Taycher

  So I keep having this small problem where I have something like func :: a -> b -> [a] -- or basically any a-> ...-> [a] where ... is any types -> func x y = func' [x] y -- as long as they are used to generate a list of [a] from x func' :: [a] -> b -> [a] func = undefined --situation dependant generates a list from each element and returns it as one long list should I keep it like this? should I use func' hidden by a where? should I only use the [a] - b - [a] version and leave the responsibility of passing [variable] to the callee? I might well need to compose these functions and might want to mess around with the order so I'm leaning towards option 3. What do you think?

• Help getting PHP sessions to persist after being taken off-site

  - by Rob

  Hi, we're working on a payment gateway system with PHP. We use sessions to store the shopping cart data. The system takes you off-site to the payment processor's site, and then return you to your site. On most hosts, we have no issues when we arrive back at our site and having the session data still be there. On those with an issue, turning off the PHP session referer_check has worked in the past. We don't really want to have to include the PHPSESSID as a GET variable, and hope to avoid that. What I'm looking for is what other server configurations would cause the session to be killed, and any other workarounds there might be. Thanks for your help.

• Stored procedure for selecting multiple records

  - by padmavathi

  I need to select records say 2000 from a table with a matching timestamp from c# .net code. Eg: SELECT * FROM ITEMDATA_TABLE WHERE ITEMNAME='Item1' and TimeStamp='2010-04-26 17:15:05.667' The above query has to execute for 2000 items more for the same timestamp. for this we can use SELECT * FROM ITEMDATA_TABLE WHERE ITEMNAME in ('Item1','Item2','Item3','Item4',......) AND TimeStamp='2010-04-26 17:15:05.667' from SQL Server Management Studio. I have tried appending all Item names to one string variable and giving it as a parameter to the stored procedure,but it resulted into a wrong concatenation. How can I do this as a stored procedure executing from the .net code? Can anyone suggest me/correct me in doing this? Thanks & Regards Padma

• Caching Models in rails

  - by jules

  I have a rails application, with a model that is a kind of repository. The records stored in the DB for that model are (almost) never changed, but are read all the time. Also there is not a lot of them. I would like to store these records in cache, in a generic way. I would like to do something like acts_as_cached, but here are the issue I have: I can not find a decent documentation for acts as cached (neither can I find it's repository) I don't want to use memcached, but something simpler (static variable, or something like that). Do you have any idea of what gems I could use to do that ? Thanks

• Generate switch cases in php from an array?

  Is it possible to generate the cases for a switch in php using an array? Something like: $x=array( 0 => 'foo', 1 => 'bar', 2 => 'foobar' ); $y='foobar' switch($y) { foreach($x as $i) { case $x: print 'Variable $y tripped switch: '.$i.'<br>'; break; } } I would like to be able to pull the case values from a database and loop through them with a while() loop.

• How to make an mutable C array for this data type?

  - by mystify

  There's this instance variable in my objective-c class: ALuint source; I need to have an mutable array of OpenAL Sources, so in this case probably I need a mutable C-array. But how would I create one? There are many questions regarding that: 1) How to create an mutable C-array? 2) How to add something to that mutable C-array? 3) How to remove something from that mutable C-array? 4) What memory management pitfalls must I be aware of? Must i free() it in my -dealloc method? And yes, I think this is something for the nice community wiki...

• pthread_exit return value

  - by Manty

  This is surprising for me. void * thread_func(void *arg) { pthread_exit(&ret); } int main(void) { pthread_t thr; int *exit_status; pthread_create(&thr, NULL, thread_func, NULL); sleep(2); pthread_join(thr, (void **)&exit_status); printf("value of exit status - %d\n", *exit_status); ret = 20; pthread_join(thr, (void **)&exit_status); printf("value of exit status - %d\n", *exit_status); return 0; } The output is value of exit status - 50 value of exit status - 20 I was expecting both the times the exit_status would be the actual exit value(50 in my case) of the thread. Instead it is just returning the value of the global variable which I used for pthread_exit. Is it not a bug?

• Dynamically changing databases in SQL Server 2000

  - by spuppett

  At work we have a number of databases that we need to do the same operations on. I would like to write 1 SP that would loop over operations and set the database at the beginning of the loop (example to follow). I've tried sp_executesql('USE ' + @db_id) but that only sets the DB for the scope of that stored procedure. I don't really want to loop with hard coded database names because we need to do similar things in many different places and it's tough to remember where things need to change if we add another DB. Any thoughts Example: DECLARE zdb_loop CURSOR FAST_FORWARD FOR SELECT distinct db_id from DBS order by db_id OPEN zdb_loop FETCH NEXT FROM zdb_loop INTO @db_id WHILE @@FETCH_STATUS = 0 BEGIN USE @db_id --Do stuff against 3 or 4 different DBs FETCH NEXT FROM zdb_loop INTO @db_id END CLOSE zdb_loop DEALLOCATE zdb_loop

• Why isn't the compiler smarter in this const function overloading problem?

  - by Frank

  The following code does not compile: #include <iostream> class Foo { std::string s; public: const std::string& GetString() const { return s; } std::string* GetString() { return &s; } }; int main(int argc, char** argv){ Foo foo; const std::string& s = foo.GetString(); // error return 0; } I get the following error: const1.cc:11: error: invalid initialization of reference of type 'const std::string&' from expression of type 'std::string* It does make some sense because foo is not of type const Foo, but just Foo, so the compiler wants to use the non-const function. But still, why can't it recognize that I want to call the const GetString function, by looking at the (type of) variable I assign it to? I found this kind of surprising.

• How can I save/print values in my WATCH list in Visual Studio 2008?

  - by Rising Star

  When I attach the Visual Studio 2008 debugger to my web server process, I sometimes browse a large amount of data in my watch list. Suppose I have an array of string variable that I expand to show 20 entries. It seems that the only way to save these values is to copy and paste them one at a time. I have gone so far as to do a screen-shot in order to have a record of what the values were (to refer to later or print a hard copy). Is there an easy way to save and print these values? I am familiar with the new "IntelliTrace" feature in Visual Studio 2010 Ultimate, but it seems overkill for this purpose. I just want to take something like an array of strings and save it for later reference once I've stopped the debugger. What's a good way to do this?

• Multiple Apps Possible via Launch Services, want to Specify Particular One

  - by Andrew

  Here's the issue: I have a list of App names that I want to launch. They do not include a path (e.g. {"VLC","Microsoft Word"}. I have two different copies of VLC in different directories. I would like Launch Services to ONLY open the one from /Applications/ and not EVER launch from /Applications/AnotherDirectory I want to get the path of these, and test to see what Launch Services wants to launch (via bash with "open" or applescript via "tell _ to launch" or [NSWorkspace launch...]) The only way that I have come up with to test the path of a file about to be launched by launch services is: Applescript: tell application "Finder" to return the (posix path of (path to application "VLC" as alias)) That works fine, but launches the app (which I don't want at all). Suggestions?

• Writing a script for reading many .csv files with similar filenames

  - by wahalulu

  I have several .csv files with similar filenames except a numeric month (i.e. 03_data.csv, 04_data.csv, 05_data.csv, etc.) that I'd like to read into R. I have two questions: Is there a function in R similar to MATLAB's varname and assignin that will let me create/declare a variable name within a function or loop that will allow me to read the respective .csv file - i.e. 03_data.csv into 03_data data.frame, etc.? I want to write a quick loop to do this because the filenames are similar. As an alternative, is it better to create one dataframe with the first file and then append the rest using a for loop? How would I do that?

• Passing Session[] and Request[] to Methods in C#

  - by NYARROW

  In C#, How do you pass the Session[] and Request[] objects to a method? I would like to use a method to parse out Session and Request paramaters for a .aspx page to reduce the size of my Page_Load method. I am passing quite a few variables, and need to support both POSTand GET methods. For most calls, not all variables are present, so I have to test every variable multiple ways, and the code gets long... This is what I am trying to do, but I can't seem to properly identify the Session and Request paramaters (this code will not compile, because the arrays are indexed by number) static string getParam( System.Web.SessionState.HttpSessionState[] Session, System.Web.HttpRequest[] Request, string id) { string rslt = ""; try { rslt = Session[id].ToString(); } catch { try { rslt = Request[id].ToString(); } catch { } } return rslt; } From Page_Load, I want to call this method as follows to retrieve the "MODE" paramater: string rslt; rslt = getParam(Session, Request, "MODE"); Thanks!

  - by yes123

  Hi guys, I am getting lot of traffic to my php pages but without the variable $_SERVER['HTTP_HOST'] setted. This traffic is like 1 hit per second. I don't know what it could be, but for reducing server load i am doing this at the top of every php pages: if (!isset($_SERVER['HTTP_HOST'])) exit; Do u know what could cause this? Is it safe to exit whenever http_host is not setted? Can a normal user visit my pages without setting http_host? PHP version: 5.2.0-8, Apache: 2.2.3 Thanks
