• Is it possible to *optionally* override a theme in Drupal 6?

  - by David Semeria

  I want to override the theming of only one (custom) menu. I can do this with phptemplate_menu_tree() but - of course - it overrides the rendering of all menus. I've tried returning FALSE (an obvious technique IMO) if the menu is not the specific one I want to override - but this doesn't cause the overridden theme function to be called. My only alternative (when the menu is anything other than the specific one) is to call the overridden function from within phptemplate_menu_tree() - but this seems to defeat the whole point of the override system, since the default rendering function will be hard-coded therein. I hope the explanation is clear, and any help is greatly appreciated - tks.

• Why does set key not do anything in AES/SymmetricAlgorithm?

  - by acidzombie24

  This MESSED ME UP hard. I thought i was setting the key but i was not. No exceptions, nothing happen except bad results. Why is there a setter if everything is ignored and no exceptions are thrown when i attempt to write? What is the point of the setter on the Keys property? When i do the below Key value are not changed. After an hour when i realize what was happening i wrote the loop to verify. I also tried aes.Key[0] = val; var b = val == aes.Key[0]; (and messed with it in immediate mode). Why does it have this behavior? Array.Copy(myKey, aes.Key, aes.Key.Length); int i = 0; foreach (var v in aes.Key) { var b = myKey[i++] == v; if (!b) b = b; }

• Loop through different sets of unique permutations

  - by user558610

  Hi I'm having a hard time getting started to layout code for this problem. I have a fixed amount of random numbers, in this case 8 numbers. R[] = { 1, 2, 3, 4, 5, 6, 7, 8 }; That are going to be placed in 3 sets of numbers, with the only constraint that each set contain minimum one value, and each value can only be used once. For example: R1[] = { 1, 4 } R2[] = { 2, 8, 5, 6 } R3[] = { 7, 4 } I need to loop through all possible combinations of a set R1, R2, R3. Order is not important, so if the above example happened, I don't need R1[] = { 4, 1 } R2[] = { 2, 8, 5, 6 } R3[] = { 7, 4 } NOR R1[] = { 2, 8, 5, 6 } R2[] = { 7, 4 } R3[] = { 1, 4 } What is a good method?

• Distribution of many small classes

  - by Moo-Juice

  Hi All, I have a base class called EventArgs. Derived from this are many, many specializations that represent event arguments for a particular kind of event. Consumers of these events may need some, many, or very few of these argument classes. My question is, would you provide a header file for each type (e.g, 50+ header files for the varying ones), would you try to group them in to families and have a 'common' header file for those, or would you throw caution to the window and throw them in to one easy-of-use header file that can just be included? Another approach might be to have 50 header files, and then I could introduce some "family" header files that included particular ones. Not sure about the naming conventions for these kinds of things so it is obvious what is where. I know there may not be a hard and fast rule, but wondering what other developers have done when they find themselves writing many little classes. Thanks in advance.

• VS2010 (older) installer project - two or more objects have the same target location.

  - by Hamish Grubijan

  This installer project was created back in 2004 and upgraded ever since. There are two offending dll files, which produce a total of 4 errors. I have searched online for this warning message and did not find a permanent fix (I did manage to make it go away once until I have done something like a clean, or built in Release, and then in Debug). I also tried cleaning, and then refreshing the dependencies. The duplicated entries are still in there. I also did not find a good explanation for what this error means. Additional warnings are of this nature: Warning 36 The version of the .NET Framework launch condition '.NET Framework 4' does not match the selected .NET Framework bootstrapper package. Update the .NET Framework launch condition to match the version of the .NET Framework selected in the Prerequisites Dialog Box. So, where is this prerequisites box? I want to make both things agree on .Net 4.0, just having a hard time locating both of them.

• Extracting friends' E-Mail addresses from Facebook (Skype?)

  - by chephy

  I am currently in the process of migrating away from Facebook (privacy concerns, mostly). For obvious reasons, I want to save away the email addresses from my friends' profile pages. However, this turned out to be a rather hard task, because the Facebook API doesn't let you access any mail addresses. However, I just tried the automatic contact import feature of Skype, and it seems to be able to retrieve the email addresses of my friends from Facebook. Does anyone know how it's done so I could replicate it?

• number of methods in an interface.

  - by Jeow

  I know this might seem a controversial question but it really is not meant to be. is there an optimal number of methods in an interface. For example, I personally hate an interface with 20 methods. It is just difficult to implement. The contract seems to hard to maintain. Similarly if the number of methods is just 1. It makes me wonder if it is really a good abstraction. Any thoughts ?

• How can specific the layout_width and layout_height of a Framelayout which fits an image

  - by michael

  Hi, I have an image which is 80px X 50 px, and I need to place that in one of the child of a FrameLayout, how can I specific the layout_width and layout_height of a Framelayout which fits an image without scaling it? I know there is a layout_height="wrap_content" layout_wight="wrap_content" for FrameLayout, but I can't use it, since that FrameLayout has other children. So I would like to hard code the FrameLayout width/height to match the dimension of the image? Should I use layout_width="80px" or layout_width="80dip"? Thank you.

• WMF image data validation?

  - by deostroll

  There is an image capturing device which gives its output in wmf. This output is stored in the database directly. We have cases where at times some of these images do not appear on a web page in IE. But if we right click on the page we are able to save the image on to the hard disk; meaning the image does exist on the page, but does not appear visible. I think this is because of some file corruption issue, but I don't know how to resolve it. We are however able to view such files using MS Picture Viewer (desktop app). Is there anyway we can detect such problematic files?

• Protecting IP for scripting projects

  - by Francisco Garcia

  There are some tasks where the obvious language choice is with scripting languages: bash, Python, Ruby, Tcl... however I find it hard to protect a company IP once the product is delivered because the application is never compiled. The client will have complete access to every single line of code. Which one are the choices to protect a product IP when it is best implemented with scripting languages? (switching to a compiled language such as C++ should not be an option) I know that some interpreted languages can be compiled, but there are cases where the process can be inverted

• I'm maintaining a java class that's 40K lines long.. problem?

  - by Billworth Vandory

  This may be a subjective question leading to deletion but I would really like some feedback. Recently, I moved to another very large enterprise project where I work as a C++ developer. I was aghast to find most classes in the project are anywhere from 8K to 50K lines long with methods that are 1K to 8K lines long. It's mostly business logic dealing with DB tables and data management, full of conditional statements to handle the use cases. Are classes this large common in large enterprise systems? I realize without looking at the code it's hard to make a determination, but have you ever worked on a system with classes this large?

• iframe reaches bottom of page

  - by John

  Is there a way to make the height of the <iframe> reach exactly the bottom of the page? It is hard to judge by using height:xx%, and it might be dependent on browser. The code is below: <!DOCTYPE html> <html> <body style="margin:0"> <p style="margin:10px"> hello </p> <iframe src="http://www.weather.com" style="width:100%; height:95%"></iframe> </body> </html>

• Hide or display a button according to row count of a table

  - by kawtousse

  Hi, i have a HTML table and a button send. First of all the send button must have this style: style.display="none". But if the table has at least one row the button should be displayed (block/inline); I still have no idea how to relate between the table and the button. I try to use JavaScript but i should think about a function and I don't found any of it to apply at type table. Thinking about CSS still also hard since I cannot find a relation between the table and the button.

• Git pull: error: Entry foo not uptodate. Cannot merge.

  - by yuit

  I'm trying to update my repo from a remote branch and keep getting this error when I do a "git pull". I haven't made any local changes, and even if I have I don't need to keep them. I've tried: git reset --hard and I get the same problem The only thing that seems to work is deleting the offending file and try a git pull again. I've also tried "git stash" followed by a "git pull". No go. edit: using PortableGit-1.6.4-preview20090729 so any previous bugs with spurious errors should be fixed.

• How to algorithmically partion a keyspace?

  - by pbhogan

  This is related to consistent hashing and while I conceptually understand what I need to do, I'm having a hard time translating this into code. I'm trying to divide a given keyspace (say, 128 bits) into equal sized partitions. I want the upper bound (highest key) of each partition. Basically, how would I complete this? #define KEYSPACE_BYTE_SIZE 16 #define KEYSPACE_BIT_SIZE (KEYSPACE_BYTE_SIZE * 8) typedef struct _key { char byte[KEYSPACE_BYTE_SIZE]; } key; key * partition_keyspace( int num_partitions ) { key * partitions = malloc( sizeof(key) * num_partitions ); // ... }

• A generic Find method to search by Guid type for class implementing IDbSet interface

  - by imak

  I am implementing a FakeDataSet class by implementing IDbSet interface. As part of implementing this interface, I have to implement Find method. All my entity classes has an Guid type Id column. I am trying to implement Find method for this FakeDbSet class but having hard time to write it in a generic way. Below is my attempts for writing this method but since it does not know about Id been Guid type, I am getting compilation error on m.Id call. Any ideas on how this could be accomplished? public class FakeDataSet<T> : IDbSet<T> where T: class, new() { // Other methods for implementing IDbSet interface public T Find(params object[] keyValues) { var keyValue = (Guid)keyValues.FirstOrDefault(); return this.SingleOrDefault(m => m.Id == keyValue); // How can I write this } }

• How can I use Amazon's API in PHP to search for books?

  - by TerranRich

  I'm working on a Facebook app for book sharing, reviewing, and recommendations. I've scoured the web, searched Google using every search phrase I could think of, but I could not find any tutorials on how to access the Amazon.com API for book information. I signed up for an AWS account, but even the tutorials on their website didn't help me one bit. They're all geared toward using cloud computing for file storage and processing, but that's not what I want. I just want to access their API to search info on books. Kind of like how http://openlibrary.org/ does it, where it's a simple URL call to get information on a book (but their databases aren't nearly as populated as Amazon's). Why is it so hard to find the information I need on Amazon's AWS site? If anybody could help, I would greatly appreciate it.

• perforce implementation of clearcase like "views"

  - by Pradyot

  I have read through the documentation on perforce and the "branching strategy" advice as well. One thing thats left me baffled, is how a simple concern is does not seem to adequtely adressed. When I am working on a project that touches many parts of our code base , I cannot checkin my code at the end of the day without checking into the trunk. So do I need to branch in this situation? I want to be able to have the ability to have a history of my changes in a long and hard project, so I can go back when I I make a wrong turn.. The problem with branching I see is that I will be creating copies of almost the entire codebase .. Am I missing an obvious solution here? thanks

• Parsing a string for dates in PHP

  - by nickf

  Given an arbitrary string, for example ("I'm going to play croquet next Friday" or "Gadzooks, is it 17th June already?"), how would you go about extracting the dates from there? If this is looking like a good candidate for the too-hard basket, perhaps you could suggest an alternative. I want to be able to parse Twitter messages for dates. The tweets I'd be looking at would be ones which users are directing at this service, so they could be coached into using an easier format, however I'd like it to be as transparent as possible. Is there a good middle ground you could think of?

• HWID locking a PHP page?

  - by Rob

  Currently I sell a program, that accesses my webpage. The program is HWID (Hard Ware ID) locked, and the only reason I use the program to access the webpage instead of direct access via a webbrowser, is so that I can use HWID authentication. However, I've just been told I can code a script to get computer information, such as hardware ID etc. Is this actually possible completely server-side? If so, can I do it with PHP? If not, what language would this be, and what functions would I have to look into for this?

• TextMate Theme Select Attribute Value

  - by HelpAppreciated

  Hello, I need to change the color of certain attributes/tags. I am switching from Dreamweaver and making the skin has been really hard in TextMate. As you can see, I want to change the a and img tags along with all of their attributes. The closest I've come to find is entity.other.attribute-name which only works with id for some reason entity.other.attribute-name.id Bonus would be the scope selector for the value of an attribute, e.g. "Logo" alt in the above example. Thank You!

• C# directory to "play with"

  - by Adam S

  Simple question here. I have a C# program which needs to stores some files onto the hard drive, but I don't need them to be anywhere useful to the end-user, only somewhere that the program can read/write from. Is there a directory that I can reference programmatically to be my "filespace playground" - that is, that I can read/write freely to and from? EDIT: Also, if I use a temp directory, how long are the files guaranteed to be there? I don't want the them to disappear while my program is still running!

• Bible reference books (PHP / MySQL / Unix)

  - by Josh K

  I'm looking for some nice heavy books to liter around my desk and make it look like I'm a hard core programmer. On the occasion that I might want to look something up they will also need to be useful dependable books. I'm looking for the equivalent bible in PHP, MySQL, and Unix. Should be laid out with some chapters I can actually read, along with having an in-depth reference to that particular subject. I know that the majority of this can be found on Google, but I would prefer it in book form.

• What's the safest way to remove data from mysql? (PHP/Mysql)

  - by ggfan

  I want to allow users as well as me(the admin) to delete data in mysql. I used to have remove.php that would get $_GETs from whatever that needed to be deleted such as... remove.php?action=post&posting_id=2. But I learned that anyone can simply abuse it and delete all my data. So what's the safest way for users and me to delete information without getting all crazy and hard? I am only a beginner :) I'm not sure if I can use POSTs because there is no forms and the data isn't changing. Is sessions good? Or would there be too many with postings, user information, comments, etc. Ex: James wants to delete one of his postings(it is posting_id=5). So he clicks the remove link and that takes him to remove.php?action=post&posting_id=5.

• Problem decrementing in Java with '-='

  - by hanesjw

  I'm making a scrolling game on Android and am having a hard time figuring out why the code below does not decrement past 0. Objects start at the end of the screen (so the x position is equal to the width of the screen) the objects move accross the screen by decrementing their x positions. I want them to scroll off of the screen, but when the x position hits 0, the objects just stay at 0, they do not move into the negatives. Here is my code to move objects on the screen private void incrementPositions(long delta) { float incrementor = (delta / 1000F) * Globals.MAP_SECTION_SPEED; for(Map.Entry<Integer, HashMap<Integer, MapSection>> column : scrollingMap.entrySet()) { for(Map.Entry<Integer, MapSection> row : column.getValue().entrySet()) { MapSection section = row.getValue(); section.x -= incrementor; } } } It works ok if I change section.x -= incrementor; to section.x = section.x - (int)incrementor; but if i do that the scrolling doesn't appear as smooth.
