• Problem with sending "SetCookie" first in php code

  - by Camran

  According to this manual: http://us2.php.net/setcookie I have to set the cookie before anything else. Here is my cookie code: if (isset($_COOKIE['watched_ads'])){ $expir = time()+1728000; //20 days $ad_arr = unserialize($_COOKIE['watched_ads']); $arr_elem = count($ad_arr); if (in_array($ad_id, $ad_arr) == FALSE){ if ($arr_elem>10){ array_shift($ad_arr); } $ad_arr[]=$ad_id; setcookie('watched_ads', serialize($ad_arr), $expir, '/'); } } else { $expir = time()+1728000; //20 days $ad_arr[] = $ad_id; setcookie('watched_ads', serialize($ad_arr), $expir, '/'); } As you can see I am using variables in setting the cookie. The variables comes from a mysql_query and I have to do the query first. But then, if I do, I will get an error message: Cannot modify header information - headers already sent by ... The error points to the line where I set the cookie above. What should I do?a

• Get single Wordpress gallery image with given title

  - by Wickethewok

  I am having users of a Wordpress blog upload a single image to different post's galleries with the name "banner". Basically, every post will have an image named "banner" uploaded to its gallery and this image needs to be displayed on the post's page outside of the article content. So, how can I get the URL to display an image in a post's single.php template? Can I iterate through the images of a given post's gallery and find the one with the correct title somehow? I've searched through the Wordpress codex docs and haven't found anything on a way to do this, just information on displaying galleries of photos. Note that I'm already using Wordpress's post thumbnail feature for something else. Thanks!

• Efficient job progress update in web application

  - by Endru6

  Hi, Creating a web application (Django in my case, but I think the question is more general) that is administrating a cluster of workers doing queued jobs, there is a need to track each jobs progress. When I've done it using database UPDATE (PostgreSQL in this case), it severely hits the database performance, because each UPDATE creates a new row in a table, and in my case only vacuuming DB removes obsolete rows. Having 30 jobs running and reporting progress every 1 minute DB may require vacuuming (and it means huge slow downs on a front end side for all the employees working with the system) every 10 days. Because the progress information isn't critical, ie. it doesn't have to be persistent, how would you do the progress updates from jobs without using an overhead database implies? There are 30 worker servers, each doing 1 or 2 jobs simultaneously, 1 front end server which serves a web application to users, and 1 database server.

• Call other activities in an activity?

  - by Mohit Deshpande

  Say I have 2 activities (ActivityOne and ActivityTwo). How would I call ActivityTwo from ActivityOne? Then how would I return to ActivityOne from ActivityTwo? For example, I have a listview with all the contacts on the host phone. When I tap on a contact, another activity shows information and allows editing of that contact. Then I could hit the back button, and I would go back to the exact state that ActivityOne was in before I called ActivityTwo. I was thinking an Intent object, but I am not sure. Could someone post some code?

• Shell Prompt Line Wrapping Issue

  - by Rob

  I've done something to break my Bash Shell Prompt in OS X (10.5.7) Terminal. This is the PS1 that I had configured: PS1='\[\e[1;32m\]\h\[\e[0m\]:\[\e[1;34m\]\w\[\e[0m\]\$ ' As far as I can tell I have the color commands escaping correctly. However when I scroll up and down in my command history I often get line wrapping issues if the historic commands wrap onto multiple lines. I simplified my prompts to the following: PS1='\[\e[1m\]\h:\w\$ \[\e[0m\]' PS2='> ' And I still see something like: localhost:~/Library/Application Support/Firefox/Profiles/knpmxpup.Defau lt/extensions/{1A2D0EC4-75F5-4c91-89C4-3656F6E44B68}$ expocd \{1A2D0EC4-7 5F5-4c91-89C4-3656F6E export PS1="\[ \e[1;32m\]\h\[\e[0m\]: cd Library/Appl ication\ Support/ I've also tried \033 instead of \e. I just included PS2 up there for information, I haven't changed that from the install default. If I completely remove the color codes then everything works fine, any ideas?

• Google App Engine: Difficulty with Users API (or maybe just a Python syntax problem)

  - by Rosarch

  I have a simple GAE app that includes a login/logout link. This app is running on the dev server at the moment. The base page handler gets the current user, and creates a login/logout url appropriately. It then puts this information into a _template_data dictionary, for convenience of subclasses. class BasePage(webapp.RequestHandler): _user = users.get_current_user() _login_logout_link = None if _user: _login_logout_link = users.create_logout_url('/') else: _login_logout_link = users.create_login_url('/') _template_data = {} _template_data['login_logout_link'] = _login_logout_link _template_data['user'] = _user def render(self, templateName, templateData): path = os.path.join(os.path.dirname(__file__), 'Static/Templates/%s.html' % templateName) self.response.out.write(template.render(path, templateData)) Here is one such subclass: class MainPage(BasePage): def get(self): self.render('start', self._template_data) The login/logout link is displayed fine, and going to the correct devserver login/logout page. However, it seems to have no effect - the server still seems to think the user is logged out. What am I doing wrong here?

• WebGL on older Mac OS X versions (say 10.4)

  - by rotoglup

  Not really a programming related question but... I'd like very much to experiment with WebGL on my spare time. My current 'spare time' machine is a MacBook running Mac OS X Tiger (10.4.xx) and I'm unable to find a new browser supporting this OS. Firefox dropped support, Chrome too, and Safari idem. I read somewhere that this is due to a Quicktime bug that Apple won't fix. Does anyone have more information on this issue ? Does anyone have a clue or track to find a running implementation of WebGL on Mac OS X 10.4 ? Cheers,

• PHP - Setting Database Info

  - by user1710648

  First off, I'm sorry if this shows no code which is not what Stack Overflow is about..But I have no clue where to go on this. I have a basic CMS I made, and I am trying to distribute it. I want to make it so that upon going to /cms/install for example, they set the database info, and different info to integrate into the CMS. Now my issue is, what would be the best method to allow the user to store that database info? A cookie seems to not be the right way..Could I store database info inside of a database? Not too sure where to go on this. More or less. What is the best way to temporarily store the database information the user gave before arrival of the full CMS.

• Can I Use EF Across Multiple DBs in One SQLServer Instance?

  - by thomashubschman

  Hello, I have been searching the blogs and articles but I have not found much support for this scenario. I have been poking around EF and realized that I could create views that contained data from multiple databases and then build the EF object model off of those views. Although it works I am not sure about the usual issues of performance, scalability, maintainability. The way I am achieving the connection between databases is by creating associations in the EF model. Does anyone have any information about this type of implementation? Either another solution or commentary on this proposed solution? Thanks, Tom

• Why is MenuItem.AdapterContextMenuInfo null when my list view has a custom adapter?

  - by gregm

  My question: Before I go and use an OnLongClickListener, is there a better way to pass the "what was clicked to create this context menu" information when your list view has a custom adapter? Here are some details: Normally, my code can just do something like this: public boolean onContextItemSelected(MenuItem item) { AdapterContextMenuInfo info = (AdapterContextMenuInfo) item.getMenuInfo(); and then go on and be happy. However, ever since I introduced a custom adapter, item.getMenuInfo() is null. This is a big problem, because my code no longer knows which item was clicked. (My custom Adapter makes each list row a checkbox and a text view) I tried this but failed: Created my own special AdapterContextMenuInfo (called "HasAViewMenuInfo"), but when I pass it in this method, it ends up being null in the menu public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) { super.onCreateContextMenu(menu, v, new HasAViewMenuInfo(v));

• How do you insert new entries into an Access db table through an ASP.net website?

  - by CGF

  I need to insert new records into an Access database. I'm using Visual Studio 2008 and firstly create a asp.net website. I can connect to the information in Access databse using dataview or gridview and can query a particular entry (ie. Proposal No. -brings up all details linking to that proposal). I can then edit the details of that proposal and this would update the Access Db. What I need to do is to have a form that simply enters new details for a new customer. ie. Enter name [__] Enter Adress[__]. Then for this to update the database. By using the gridview or dataview I am able to view all fields that exist in the table and edit them. Is there a way that I can get a blank gridview/dataview template (which includes all the fields in the table) and fill it out to then update the database? Thanks

• Server Side code Pushing Data to client Browser while current thread is busy Comet (programming)

  - by h_power11

  Hello Friends, I am writing one simple web page with bunch of textboxes and a button control. Now when user finished editing the values on this text boxes user has to click the button and this button invoke heavily process intensive algorithm on server side code based on the data received from client (Textboxes) And it could some time takes up to 30 to 45 minutes to complete the whole operation so the current thread is still inside the button click event handler function. That background task only provides one event, and the web page subscribes to it to get some text data after each stage of processing I was wandering if there is any way I can keep user up-to-date with what is the current progress on that background task. I have div element to print the current status information So I am looking for some sort of reverse mechanism then "get" and "post". I have read some articles on the Comet (programming) but I can't find any easy or definitive answer Thanks in advance

• where clausule on field defined by sub-query

  - by stUrb

  I have this query which displays some properties and count the number of references to it from an other table: SELECT p.id,p.propName ( SELECT COUNT(*) FROM propLoc WHERE propLoc.propID = p.id ) AS number FROM property as p WHERE p.category != 'natural' This generates a good table with all the information I want to filter: id | propName | number 3 | Name 1 | 3 4 | Name 2 | 1 5 | Name 3 | 0 6 | Name 4 | 10 etc etc I now want to filter out the properties with number <= 0 So I tried to add an AND number > 0 But it reacts with Unknown column 'number' in 'where clause' apparently you can't filter on a name specified by a subquery? How can I achieve my goal?

• Handling orientation changes yourself

  - by synic

  From the documentation regarding the android:configChanges='orientation' attribute of the activity tag in the manifest: Note: Using this attribute should be avoided and used only as a last-resort. Please read Handling Runtime Changes for more information about how to properly handle a restart due to a configuration change. Why does it say this? In the case of threads and networking requests via a service API library, a request could be made with a reference to the original Activity, and then an orientation change could occur, leaving the thread pointing to the old Activity. While this can be fixed, it's tedious and ugly compared to just handling the configuration changes yourself. Why should it be avoided?

• Why isn't the new() generic constraint satisfied by a class with optional parameters in the construc

  - by Joshua Flanagan

  The following code fails to compile, producing a "Widget must be a non-abstract type with a public parameterless constructor" error. I would think that the compiler has all of the information it needs. Is this a bug? An oversight? Or is there some scenario where this would not be valid? public class Factory<T> where T : new() { public T Build() { return new T(); } } public class Widget { public Widget(string name = "foo") { Name = name; } public string Name { get; set; } } public class Program { public static void Main() { var widget = new Widget(); // this is valid var factory = new Factory<Widget>(); // compiler error } }

• C# Object Array CopyTo links both arrays' values?

  - by Dutchie432

  Okay, I have what I think is a simple question.. or just a case of me being a C# beginner. I have an array of custom objects (clsScriptItem) that I am populating from a database. Once the items are loaded, I want to back them up to "backup" array so I can revert the information back after changing the main array. However, when I use CopyTo to copy the array and then alter the original array, the backup array is also being altered... I though CopyTo merely copied values + structure from one array to another. private void backupItems() { lastSavedItems = new clsScriptItem[items.Length]; items.CopyTo(lastSavedItems, 0); //items[0].nexts[0] is 2 //lastSavedItems[0].nexts[0] is 2 items[0].nexts[0] = "-1"; //items[0].nexts[0] is -1 //lastSavedItems[0].nexts[0] is also -1 } How do I backup this data without having the two arrays be 'linked'??

• What was your first home computer?

  - by Adam Tegen

  What was your first home computer? The one that made you "fall in love" with programming. There are 300+ entries, many (most?) of which are duplicates. As with all StackOverflow Poll type Q&As, please make certain your answer is NOT listed already before adding a new answer - searching doesn't always find it (model naming variations, I assume). If it already exists, vote that one up so we see what the most popular answer is, rather than duplicating an existing entry. If you see a duplicate, vote it down so the top entries have only one of each model listed. If you have interesting or additional information to add, use a comment or edit the original entry rather than creating a duplicate.

• WIN32 visual c++

  I would like to write a simple program in c++. After the program is done i would like to get my answers in form of a graph or picture that would give some certain information if i click on a certain area. i have only written console apllications in c++ before and don't really have a clue where to start with the graphic part of it all. Can I write the first part of the program in console mode and some how run it under the WIN32 later? for ex what will happen to the cout<<"foo"; commands? Is there a simpler approach to do some very basic graphic programming.

• Python: UTF-8 problems (again...)

  - by blahblah

  I have a database which is synchronized against an external web source twice a day. This web source contains a bunch of entries, which have names and some extra information about these names. Some of these names are silly and I want to rename them when inserting them into my own database. To rename these silly names, I have a standard dictionary as such: RENAME_TABLE = { "Wsird" : "Weird", ... } As you can see, this is where UTF-8 comes into play. This is the function which performs renaming of all the problematic entries: def rename_all_entries(): all_keys = RENAME_TABLE.keys() entries = Entry.objects.filter(name__in=all_keys) for entry in entries: entry.name = RENAME_TABLE[entry.name] entry.save() So it tries to find the old name in RENAME_TABLE and renames the entry if found. However, I get a KeyError exception when using RENAME_TABLE[entry.name]. Now I'm lost, what do I do? I have... # -*- coding: utf-8 -*- ...in the top of the Python file.

• Feed char array into stdin

  - by Brian Lindsey

  I am writing a parser for a mini scripting language. Some of my grammar rules require jumping to a different location in the file to obtain information. There doesn't seem to be a straightforward way to accomplish this. So, I was thinking about loading my data files into a char array array and parsing line by line. This will allow me to jump all over the array with ease. My question is, is it possible to feed char arrays (i.e. char *) into stdin, so I can easily invoke the yyparse() function as needed.
