• RewriteRule help

  - by Camran

  I have successfully setup htaccess to do this: domain.com/ad.php?ad_id=bmw_m3_2498224 INTO: domain.com/ads/bmw_m3_2498224 However, I have a link on the page which makes the page submit to itself... The link saves the ad inside a cookie: domain.com/ad.php?ad_id=bmw_m3_2498224&save=1 // Note the 'save' variable I need to make this work on the rewritten rule also, so this link: domain.com/ads/bmw_m3_2498224/save will save the cookie... I have this so far which DOES NOT work for the save part: RewriteRule ^annons/([a-zA-Z0-9_]+)$ ad.php?ad_id=$1 [NC,L] How can I include another rule to accomplish what I want? Thanks

• Showing an image after loading it from sql database

  - by user330075

  I have a problem showing the image form database in a view Details and a ImageController. Inside the view I have: img src=Url.Action("GetFile","Image", new {id= Model.id}) and in controller: public FileContentResult GetFile(int idl) { //int idl = 32; SqlDataReader rdr; byte[] fileContent = null; ........... return File(,,); } When the view is called, function GetFile it just won't work. But if I cut out the parameter int id1 and I instantiate it as a variable it does work. public FileContentResult GetFile() { int idl = 32; SqlDataReader rdr; byte[] fileContent = null; ........... return File(,,); } Why?

• NSCFType keeps occurring, something is not being released?

  - by user1493543

  I'm attempting to delete files from the documents directory using a tableview/array combination. For some reason, my NSString pointing to the Documents directory path is being converted to a NSCFType (which after some research, I understand is happening because a variable is not being released). Because of this, the application crashes at the line NSString *lastPath = [documentsDirectory stringByAppendingPathComponent:temp]; claiming that NSCFType cannot recognize the method stringByAppendingPathComponent. I would appreciate if someone could help me out (I hope I have explained this clearly enough). - (void) tableView: (UITableView *) tableView commitEditingStyle: (UITableViewCellEditingStyle) editingStyle forRowAtIndexPath: (NSIndexPath *) indexPath { if (editingStyle == UITableViewCellEditingStyleDelete) { NSString *temp = [directoryContent objectAtIndex:indexPath.row]; NSLog(temp); NSString *lastPath = [documentsDirectory stringByAppendingPathComponent:temp]; [[NSFileManager defaultManager] removeItemAtPath:lastPath error:nil]; - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); documentsDirectory = [paths objectAtIndex:0]; directoryContent = [[[NSFileManager defaultManager] contentsOfDirectoryAtPath:documentsDirectory error:nil] retain]; //tableview handling below }

• C++ IDE for Linux with smart reference searching

  - by Dmitry Yudakov

  Is there an IDE supporting C++ with REALLY smart searching of references? By 'reference' I mean usage of a class (or its member), variable, function in the whole Project or Workspace. There's lots of IDE providing it. Some of them seem just to search for the text with same name giving lots of stuff, others are smarter and check the context (like class boundaries, namespace) but aren't accurate enough. The best I've tried so far was Visual SlickEdit, but still there's more to wish. class C1 { int foo; }; class C2 { int foo; }; For example in this situation when searching for C1::foo references I don't want C2::foo to be shown too. So, is there an IDE that would be so smart?

• What are the implications of using static const instead of #define?

  - by Simon Elliott

  gcc complains about this: #include <stdio.h> static const int YY = 1024; extern int main(int argc, char*argv[]) { static char x[YY]; } $ gcc -c test1.c test1.c: In function main': test1.c:5: error: storage size of x' isn't constant test1.c:5: error: size of variable `x' is too large Remove the “static” from the definition of x and all is well. I'm not exactly clear what's going on here: surely YY is constant? I had always assumed that the "static const" approach was preferable to "#define". Is there any way of using "static const" in this situation?

• ucommerce: how to change category template

  - by autonomatt

  Using uCommerce 2, umbraco 4.7. I have a category side nav showing the categories using: <a> <xsl:attribute name="href"> <xsl:value-of select="CommerceLibrary:GetNiceUrlForCategory($catalogueName, @id)"/> </xsl:attribute> <xsl:value-of select="@displayName"/> </a> First of all, when hovering over the links it still shows an old catalogue name, even though I've renamed the catalogue and also hardcoded the catalogue name into: <xsl:variable name="catalogueName" select="'MyCatalogue'"/> When I click on the link generated by GetNiceUrlForCategory I get the standard template that comes with uCommerce started site. I've tried deleting the whole started site, but I just can't get it to link to a template I did for the category. I still don't quite understand how ucommerce knows which template to use for a category link. Soren? :) Cheers, Matt

• Turing's Craft exercise stumped me... seems too easy.

  - by Chris

  "Write a for loop that prints the integers 1 through 40, separated by spaces or new lines. You may use only one variable, count which has already been declared as an integer." So I use... for(count = 1; count <= 40; count++) { cout << " " << count; } but they are using stdio.h as the only header and cout is not recognized. It hints that the output format should be (" ",count), but I can't figure out what print function to use. stdio.h can use fprintf or fwrite, but I don't have enough parameters for either function. Any ideas?

• Detecting Visual Studio Smart-tags events

  - by devoured elysium

  Is it possible to detect with VSX when any (or a particular) smart tag event is happening? I mean, every time we rename a variable, for example, a smart tag is available that allows us to change it through a form. I'd like to know if I can access that "text is changing" event. I don't mean to have to check for myself if the text is being changed and such, I'd like to make use of VS event system (if there is one). I gave this example but I'd like to know the "general system" of how smart tags work with VSX. Thanks

• mySQL php query - news/ friends feed

  - by rpsep2

  I want to show a user the recent uploads from their friends. I have the users friends id's in an array: $friends A user could have, potentially, thousands of friends. I can select the uploads from 1 of a users friends with: $row = $mysqli->query("SELECT * FROM photos WHERE uploader_id = ".$friend." ORDER BY date_uploaded DESC LIMIT ".$page.", 25"); But I need to find all of a users friends uploads. I thought about doing this in a loop iterating over the $friends array, but then I'd be potentially running thousands of mysql queries. How can I do this most efficiently? so to clarify: search a 'photos' table for photos which are uploaded by specific users(friends), held in $friends variable, sort by date_uploaded and limit to x results so I can have pages 1, 2, 3 etc.

• Can C/C++ compiler report struct member offset

  - by Chen Jun

  Hello, everyone. I'd like to ask, can compiler(e.g. Visual C++) generate a report(.txt) telling struct member offset for a struct/all structs? If so, it helps debugging quite a lot. For example, when you read disassembler code in the debugger, it can be easier to associate an offset value to a struct member. Also, it is better to have compiler report offset of each local variable on a function stack frame(e.g. the offset relative to ebp on an X86 machine). Thank you in advance.

• Count down timer

  - by Ohmnastrum

  I have a timer set up and it gets called when ever the player is in their turn phase. I also have a multiplier that decrements slowly while the player is committing actions. for some odd reason my mult variable is returning garbage values I initialized it to 1 in the onLoad statement but it still seems to have trouble. -(void) Timerbar:(NSTimer *)barTimer { if(!waitForPlayer) { [barTimer invalidate]; } if(mult > 0.0) { mult -= 0.01; if(mult < 0) { mult = 0; } } power = (mult * 10) / pwrBarMaxWidth; pwrBarWidth = (int)power % limit; NSLog(@"%d", mult); } Do I have a syntax error somewhere?

• Why doesn't splicing an object from an array in Javascript return the array?

  - by Allen Gould

  I have an array of objects (say, a deck of cards): var deck = []; deck.push(new Card(suit, rank)); The following seems to work: var card = deck.pop(); var card = deck.shift(); (pulling from the "top" or "bottom" of the deck respectively) But if I want a card from the middle (say, if this was a hand of cards) var card = deck.splice(2,1); The object doesn't seem to get properly assigned to the variable (everything is undefined). Everything I look up says that splice should return the object that I'm removing - what am I missing?

• How is the Trac Project List page customised?

  - by Completenutter2

  We've been using Trac for a while now for our developers only. However we are now opening it up for our (internal) clients. We have a project listing page (based on the default one that comes with Trac). What we'd like to do, is display more information about the project than what is currently available. I have searched google and here, to see if I can find how to get more information. There seems to be a variable called $project which has .name, .description and .href as attributes. Is there somewhere, a list of the attributes available? Or perhaps a different solution altogether that will allow us to display more information on the project list page. Such as the number of open tickets etc.

• Updating Activity UI from Different Activity Method?

  - by stormin986

  I have a tab widget where one of the tabs is a chat-type feature. I want to update the chat data at an interval (variable depending on whether the chat tab is active or not). The best approach seemed to be using an AsyncTask in my main TabActivity class, as that would avoid any issues of the chat activity being destroyed while in the background, while an AsyncTask was running. I wanted to ensure that the Activity isn't destroyed and recreated, thus causing my AsyncTask to be unable to modify the actual active Activity's data. However, now that my AsyncTask is in the TabActivity activity, I don't have a direct way to call my Chat's ListAdapter notifyDataSetChanged() from my onPostExecute() method anymore. Is there a way to get a reference to a given Tab's current Activity from the TabHost/TabActivity? Or, alternatively, can I assume my chat activity will never be destroyed as a child activity of the TabActivity activity (well, never destroyed while the TabActivity is active at least), and then just put the AsyncTask in the Chat Activity?

• Scrapy + Eclipse PyDev : how to setup the debugger?

  - by AsTeR

  I've successfully setup Eclipse with my Scrapy project. I did it by setting a new Run/Debug configuration : Whose main module links to Scrapy /usr/local/bin/scrapy for me (I've found suggestion to use cmdline.py but that failed on my computer (OSX Lion & scrapy installed through easy_install) Defining the arguments to send "crawl ny" in my case as I would if I used the Scrapy command line Setting the correct working directory (${workspace_loc:My Project/src} in my case) Eclipse can successfully launch my project, but I've no debbuger. I'm missing my breakpoints and variable inspection, does anyone know how to setup the debbugger with this environment ?

• Ruby w/ Postgres & Sinatra - Query won't order right with parameter??

  - by alleywayjack

  So I set a variable in my main ruby file that's handling all my post and get requests and then use ERB templates to actually show the pages. I pass the database handler itself into the erb templates, and then run a query in the template to get all (for this example) grants. In my main ruby file: grants_main_order = "id_num" get '/grants' do erb :grants, :locals => {:db=>db, :order=>grants_main_order, :message=>params[:message]} end In the erb template: db = locals[:db] getGrants = db.exec("SELECT * FROM grants ORDER BY $1", [locals[:order]]) This produces some very random ordering, however if I replace the $1 with id_num, it works as it should. Is this a typing issue? How can I fix this? Using string replacement with #{locals[:order]} also gives funky results.

• a nicer way to create structs in a loop

  - by sandra

  Hi guys, I haven't coded in C++ in ages. And recently, I'm trying to work on something involving structs. Like this typedef struct{ int x; int y; } Point; Then in a loop, I'm trying to create new structs and put pointers to them them in a list. Point* p; int i, j; while (condition){ // compute values for i and j with some function... p = new Point; p* = {i, j}; //initialize my struct. list.append(p); //append this pointer to my list. } Now, my question is it possible to simplify this? I mean, the pointer variable *p outside of the loop and calling p = new Point inside the loop. Isn't there a better/nicer syntax for this?

• c style thread creation in python

  - by chandank

  Hi I am new to python and want to create multiple threads in a loop something like (in C style) for (;i < 10; i++) thread[i]= pthread_create(&thread[i],&attr,func) I am not sure how to do the same in python? Basically I want have that thread[] variable as global will create all thread at once and then will start then in once. I have written a similar python program that does it but I think having it in above style will be better. def thread_create(thread_number): command_string = "Thread-" + "%d" %thread_number thread = myThread(thread_number, command_string) thread.start() # Start new Threads for i in range(5): thread_create(i)

• $("body").scrollTop() doesn't update in safari

  - by Kristoffer Nolgren

  I'm working on a website: http://beta.projektopia.se/ the body has several background-images that are updated on scroll like this: $(document).ready(function(){ $(document).scroll(function(){ var scrollfactor=$("body").scrollTop()*0.2; var centerscrollpos =scrollfactor+613; var docheight = $(document).height(); var windowheight = $(window).height(); var bottompos = (docheight-980)-((docheight-windowheight)*0.2)+scrollfactor; var scrollpos = 'center '+scrollfactor+'px,center '+bottompos+'px, center '+ centerscrollpos+'px,center 0px'; $("body").css("background-position", scrollpos); }); }); Lots of calculations, but the important thing is that a scrollpos is created that should change the position of the background when you scroll, to create a parallax-effect. It works great in chrome, but in firefox, the variable scrollfactor, that is suppose to get the current scroll-position, doesn't update. ps, some people have this issue due to lack of correct doctype. I believe i have declared it correctly like this: <!DOCTYPE html>

• How to disable a warning in Delphi about "return value ... might be undefined"?

  - by Lasse V. Karlsen

  I have a function that gives me the following warning: [DCC Warning] filename.pas(6939): W1035 Return value of function 'function' might be undefined The function, however, is clean, small, and does have a known, expected, return value. The first statement in the function is: Result := ''; and there is no local variable or parameter called Result either. Is there any kind of pragma-like directive I can surround this method with to remove this warning? This is Delphi 2007. Unfortunately, the help system on this Delphi installation is shot, so I can't pop up the help for that warning right now. Anyone know off the top of their head what I can do?

• How to Implement Dynamic Timestamp in Web Page?

  - by Morgan Cheng

  In Facebook and twitter, we can see that there is a timestamp like "23 seconds ago" or "1 hour ago" for each event & tweet. If we leave the page for some time, the timestamp changes accordingly. Since it is possible that user machine doesn't have same system time as server machine, how to make the dynamic timestamp accurate? My idea is: It is always based on server time. When request is sent to server for the web page, timestamp T1 (seconds to 1970/1/1) is rendered into inline javascript variable. The displayed timestamp ("23 seconds ago") is calculated by T1 instead of local time. I'm not sure whether this is how Facebook/Twitter do it. Is there any better idea?
