• What does this statement mean ? printf("[%.*s] ", (int) lengths[i],

  - by Vivek Goel

  I was reading this page http://dev.mysql.com/doc/refman/5.0/en/mysql-fetch-row.html there is one line printf("[%.*s] ", (int) lengths[i], row[i] ? row[i] : "NULL"); from code MYSQL_ROW row; unsigned int num_fields; unsigned int i; num_fields = mysql_num_fields(result); while ((row = mysql_fetch_row(result))) { unsigned long *lengths; lengths = mysql_fetch_lengths(result); for(i = 0; i < num_fields; i++) { printf("[%.*s] ", (int) lengths[i], row[i] ? row[i] : "NULL"); } printf("\n"); } what does [%.*s] mean in that code ?

• python: creating a list inside a dictionary

  - by user1871081

  I just started using python and I'm trying to create a program that will read a file that looks like this: AAA x 111 AAB x 111 AAA x 112 AAC x 123 ... the file is 50 lines long and I'm trying to make the letters into keys in a dictionary and the numbers lists that correspond with the keys. I want the output to look like this: {AAA: ['111', '112'], AAB: ['111'], AAC: [123], ...} This is what I've tried file = open("filename.txt", "r") readline = file.readline().rstrip() while readline!= "": list = [] list = readline.split(" ") j = list.index("x") k = list[0:j] v = list[p + 1:] d = {} if k in d == False d[k] = [] d[k].append(v) else d[k].append(v) readline = file.readline().rstrip() I keep getting syntax errors on my if statement and I can't figure out what I've done wrong.

• Android: Maps - Best way to provide 'search for location' feature?

  - by r3mo

  Hello all, I've got an android app that uses a map activity and serves up content based on map location. I'm looking for a way to allow the user to search for a location by name (anything from 'New York' to 'Eiffel Tower') - e.g. have a text input field into which they could type 'Rome' - after pressing a button, the user would be brought to the coordinates of Rome on the map. What would be the best way to go about this? I've looked into the google geocoding api (http://code.google.com/apis/maps/documentation/geocoding/), but it has limitations of 2,500 geolocation requests per day - I'm presuming this is per API key? Or is it per user/source IP? 2,500 requests for one android app woudln't last long. Ideally, I would be able to search for English and foreign names of countries. Thanks in advance! r3mo

• Fork a process and send data to it inside Rails

  - by taro

  I'm making a Rails application. In the one action I need to spawn a long running process. This is not a problem. I can fork new process using spawn gem or some other. But some time after process has been spawned, user must be able to pass additional data to that process. Sure, I can fork process which will listen a UNIX socket, store socket address in the HTTP session and communicate with that process using drb protocol when user will require to pass new data to process. But I think it is not best solution and it will be a problem to deploy an application to the hosting. What is the easy way to do that?

• Communication between .net winform and webform

  - by Pablo

  Hi, I need to make a webform communicate with a winform and back to the webform. The reason for this is it exists a webform software already made, and now it's needed the behavior of a .net component only available for winforms. We've tried going with Process.Start and shell.execute but with this approach the software hangs or it takes too long to respond. The webform also needs to be called from client pcs in the network, I think this adds another problem due to the non possibility of calling the execution of a file from a webform remotelly, but I dont know much about this technical issue we've read some articles about embedding a winform in a webform, sending data from a winform to a webform, etc. and we would like to know what's the recommend approach (if there is any) for handdling a situation like this.

• Pass the current state of a function into another function in C/C++

  - by sand

  Is there a way to pass the current state of a function into another function in C/C++? I mean all the parameters and local variables by current state. For example: void funcA (int a, int b) { char c; int d, e; // Do something with the variables. // ... funcB(); // Do something more. } void funcB() { // funcB() should be able to access variables a,b,c,d & e // and any change in these variables reflect into funcA(). } The code is in bad shape if there is a need for funcB() kind of functions. But can it be achieved? This can help if someone is starting to re-factor a long method with multiple parameters.

• Javascript Pointers question with Dates

  - by Mega Matt

  I noticed this situation in my code (unfortunately), and was able to duplicate it in my own JS file. So I have this code: var date1 = new Date(); // today var date2 = date1; date2 = date2.setDate(date2.getDate() + 1); // what is date1? After this code executes, date1 is today's date + 1! This harkens back to my undergrad days when I learned about pointers, and I guess I'm a little rusty. Is that what's happening here? Obviously I've moved the assignment away from date1, and am only modifying date2, but date1 is being changed. Why is this the case? Incidentally, after this code executes date2 is a long number like 1272123603911. I assume this is the number of seconds in the date, but shouldn't date2 still be a Date object? setDate() should return a Date object... Thanks for the help.

• Way to check for foreign key references before deleting in MySQL?

  - by Chad Johnson

  I'm working with a content management system, and users are prompted with a confirmation screen before deleting records. Some records are foreign key referenced in other tables, and therefore they cannot be deleted. I would like to display a message beside a given record if it has foreign key references. To know whether I should display the message for a record, I could just query the referencing table and see if there are references. But the problem is, there are about a dozen tables with records potentially referencing this record, and a lookup could take a "long" time. Is there an easy way to tell whether the record is delete-ready (ie. has no foreign key references)?

• Using regular expressions with Dojo data.fetch?

  - by Dfowj

  I'm trying to use the below code to fetch a regular expression like this /[computer]{3,8}/(what i think is any words containing the letters in computer ranging from 3 to 8 letters long) from a database (which i know is being loaded correctly). When i fetch, i get 10 results, all the same word... "Adenauer" var base = "computer"; var baseRE = '/[' + base + ']{' + this.minLength + ',' + base.length + '}/'; this.dict.fetch({query: {word:baseRE}, onComplete: onLoadWords, onError: function(err) { console.log(err); }}); Any ideas what im doing wrong?

• What is the best way to make a game timer in Actionscript 3?

  - by Nuthman

  I have built an online game system that depends on a timer that records how long it took a player to complete a challenge. It needs to be accurate to the millisecond. Their time is stored in a SQL database. The problem is that when I use the Timer class, some players are ending up getting scores in the database of less than a second. (which is impossible, as most challenges would take at least 11 seconds to complete even in a perfect situation.) What I have found is that if a player has too many browser windows open, and/or a slow computer, the flash game slows down actually affecting the timer speed itself. The timer is 'spinning' on screen so you can physically see the numbers slowing down. It is frustrating that I cannot just open a second thread or do something to allow flash to keep accurate time regardless of whatever else is going on in the program. Any ideas?

• Creating Pages with unique PageMaps

  - by Michael Krauklis

  I have a wicket Application that has long lived Pages. I would like each instance of this Page to be created with a unique PageMap for reasons I won't get into here, but when I try to specify a PageMap on the constructor of my Page I end up getting OOM and StackOverflow errors. Here is the code: public <CTOR>() { super(Session.get().newPageMap("" + System.currentTimeMillis())); ... I'm using a custom BookmarkablePageLink (custom in that it does not pass on the current PageMap name to the new Page) to effectively abandon the old Page/PageMap and create a new one with a new PageMap. The errors seem to be coming from page serialization after only two or three pages have been created. Can anyone find issue with this approach?

• Re-use aliased field in SQL SELECT STATEMENT

  - by Bad Display Name

  Hi, the question is hard to define without giving an example, e.g. I'd like to achieve something like this : SELECT (CASE WHEN ...) AS FieldA, 20 + FieldA AS FieldB FROM Tbl Assuming that by "..." I've replaced a long and complex CASE statement, hence I don't want to repeat it when selecting FieldB and use the aliased FieldA instead. IS THIS EVEN POSSIBLE? What could be a workaround? Note, that this will return multiple rows , hence the DECLARE/SET outside the SELECT statement is no good in my case. PLEASE HELP. P.S. I am using SQL 2008

• (L)GPL license questions

  - by Marco

  I'm uncertain about a few licensing questions. I develop a closed source application, that's communicating with an open source server. Are my assumptions correct? Can I use an unmodified (L)GPL software on the server-side? I think yes Can I use and modify (L)GPL software on the server-side? I think yes because I'm not distributing the server application The client uses an communication library licensed under LGPL. Can I make changes to this library? Yes, as long as I provide the source of the library with the client software Can I take only certain parts of an LGPL licensed software and make a new project? Yes if it's licensed under LGPL too.

• hunting maven dependencies

  - by Tom

  I want to start using maven in code I distribute but I can't find an efficient way to work with dependencies. Every new dependency takes me far too long to add. As a simple example, I need to add Tomcat for compilation. Do I really have to manually trawl the repo in my browser to find the group-id, artifact-id and version number? In every case it seems easier to find the non-maven downloads. I hope I've missed something obvious.

• Question about the String.replaceAll() and String.replaceFirst() method.

  - by Java Doe

  I need to do a simple string replace operation on a segment of string. I ran into the following issue and hope to get some advice. In the original string I got, I can replace the string such as to something else. BUT, in the same original string, if I want to replace a much long string such as the following, it won’t work. Nothing gets replaced after the call. <div class="more"><a href="http://SERVER_name/profiles/atom/mv/theboard/entries/related.do?email=xyz.com&ps=20&since=1273518953218&sinceEntryId=abc-def-123-456">More...</a></div> I tried these two methods: originalString.replaceFirst(moreTag, newContent); originalString.replaceAll(moreTag, newContent); Thanks in advance.

• computational puzzles (brute force)

  - by acidzombie24

  Not that i need it but it was interesting to hear someone speak about their server and protecting it from DOS attack by having a puzzle that the client must solve before the server will do anything (it doesnt do allocations or make a session unless solved). The person also said puzzles can be made to take a quick amount of time or long. And they are easy to check if it is solve correctly but difficult to solve. What are these puzzles? I never heard of one. Can someone give an example (link?)

• IE 7 CSS problem with detecting mouse over on div

  - by BeaverProj

  I have a div inside an li as part of a top navigation for a website. I'm having trouble with IE 7 having "holes" in the box such that the drop down disappears when the user is still on the drop down. I started with a pure CSS solution (li:hover) and that works awesome in all browsers except IE 7. So I've now added a jQuery/javascript solution to detect when the mouse enters and exits the nav li and then add a class to show the drop down. It works better, but if the mouse is not over an image, p, h3, or a tag then it doesn't think I'm over the div that is the drop down. Very frustrating. I can post some test code, but the issue can be viewed here: http://davincidays.org/ Anyone have any ideas? I've been working on this for waaaay too long already and need some fresh things to try.

• ASP SaveToDisk method takes an incredible amount of time

  - by burnt_hand

  This is a method in ASP Classic that saves a file to disk. It takes a very long time but I'm not sure why. Normally, I wouldn't mind so much, but the files it handles are pretty large so need this needs to faster than 100kB a second save. Seriously slow. (old legacy system, band aid fix till it gets replaced...) Public Sub SaveToDisk(sPath) Dim oFS, oFile Dim nIndex If sPath = "" Or FileName = "" Then Exit Sub If Mid(sPath, Len(sPath)) <> "\" Then sPath = sPath & "\" '" Set oFS = Server.CreateObject("Scripting.FileSystemObject") If Not oFS.FolderExists(sPath) Then Exit Sub Set oFile = oFS.CreateTextFile(sPath & FileName, True) For nIndex = 1 to LenB(FileData) oFile.Write Chr(AscB(MidB(FileData,nIndex,1))) Next oFile.Close End Sub I'm asking because there are plenty of WTF's in this code so I'm fighting those fires while getting some help on these ones.

• Fstream's tellg / seekg returning higher value than expected. Help is appreciated

  - by Cosmin

  Why does this fail, it's supposed to be simple and work ? fisier.seekg(0, ios::end); long lungime = fisier.tellg(); This returns a larger value than that of the file resulting in a wrong char *continut = new char[lungime]; Any idea what the problem could be ? I also tried counting to the end of the file one char at a time, that rendered the same result, a higher number than expected. But upon using getline() to read one line at a time, it works, there are no extra spaces... Thank you

• Why can't I register a custom model binder for a List<int>?

  - by quarksoup

  I have an action that looks like public ActionResult GetUsers(List<int> userIds) {//do stuff} The list of userIds can become quite long, so I want to use Json.Net to deserialize it. To do so I created an IModelBinder implementation, which works fine for other objects, but never gets called for a List. The IModelBind looks like this public class JsonBinder : System.Web.Mvc.IModelBinder { public object BindModel(System.Web.Mvc.ControllerContext controllerContext, System.Web.Mvc.ModelBindingContext bindingContext) { //Do model binding stuff using Json.Net } } And I register this model binder with this line ModelBinders.Binders.Add(typeof(List<int>), new JsonBinder()); However the JsonBinder is never called. Why is this? Should I be using a ValueProvider?

• what happen if I delete the xx.jar file after I started to execute the xx.jar

  - by ogzylz

  I have a server program running a java binary code (xx.jar file) While it is running I erranously delete the xx.jar file. The program continues to run. But I am not sure if the results will be correct, and I am not sure if the program will fail? When I delete the xx.jar file, the program was in a method for a long time and still it is in that method call. When it calls another method call will my program fail? I am asking this question because If deleting the file has no harm I will be gaining about 3-4h on a server machine

• Permission error while trying to access an (server) program started by a Java program.

  - by Zardoz

  I am starting a server application (normally to be started from the Unix command line) by using Runtime.getRuntime().exec("path/mmserver"). My problem is now that as long as my Java program, which started that server runs, the server is correctly accessible (from command line and other programs). But when my Java program exits the sever is not accessible anymore (the process of the server is still running). I just get such a error message when trying to access the server: "Error: permission_error(flush_output(user_output),write,stream,user_output,errno(32))". The server is a blackbox for me. I am just looking for other ways to start a new process. And maybe someone has a hint why I get that permission error (even if one doesn't know what that server exactly is ... you rather won't know it).

• How can you prevent a window being captured by Print-Screen?

  - by John

  I noticed a few times than when I print-screen while Media Player is running, the content is replaced with a grey rectangle. I've no idea if it's deliberate due to DRM, or some technical issue, but it struck me that being able to deliberately block screen-capture might be a useful feature in some scenarios. Is there some specific message each HWND gets for print-screen - does Windows do a special repaint or simply dump buffers to the clipboard? I guess I'd prefer to focus this on Win32 specifically, but as long as it's Windows-related then fine.

• INSERT INTO ... SELECT ... vs dumping/loading a file in MySQL

  - by Daniel Huckstep

  What are the implications of using a INSERT INTO foo ... SELECT FROM bar JOIN baz ... style insert statement versus using the same SELECT statement to dump (bar, baz) to a file, and then insert into foo by loading the file? In my messing around, I haven't seen a huge difference. I would assume the former would use more memory, but the machine that this runs on has 8GB of RAM, and I never even see it go past half used. Are there any huge (or long term) performance implications that I'm not seeing? Advantages/disadvantages of either?

• How do I get broadcast to work with djcelery+ghettoq

  - by user560833

  I am using djcelery 2.1.4 with ghettoq 0.4.5 and django 1.2.3 and I am able to run tasks all day long, but when I try to use any broadcast functionality it fails without errors. Take the simplest case -- I run celeryd: python manage.py celeryd The daemon starts and I try to run a ping: >>> from celery.task.control import ping >>> ping() [] I can see the message that ping created appear in the database, but apparently none of the nodes are picking it up? Am I doing something wrong here? Does broadcast not work with carrot?
