• C# Get Keys from a Dictionary<string, Stream>

  - by alex

  Suppose I have a Dictionary like so: Dictionary<string, Stream> How can I get a list (or IEnumerable or whatever) of JUST the Keys from this dictionary? Is this possible? I could enumerate the dictionary, and extract the keys one by one, but I was hoping to avoid this. In my instance, the Dictionary contains a list of filenames (file1.doc, filex.bmp etc...) and the stream content of the file from another part of the application.

• How to filter Wordpress posts using a hook in a plugin?

  - by Davide

  I'm creating a Wordpress plugin and, being a newbie in the development on this platform, I'm stuck on this problem. I'd like to have posts in the loop filtered by categories, defined by the user through an admin page. I would actually like to be able to modify query_post() parameters in the plugin, but the only trick I found is to re-run the query_post() with my user-defined criteria, thing that I would like to avoid. I'm sure the solution is evident, but can't find it!

• How to prevent shortcuts from firing when form is not active

  - by Erick Sasse

  I open forms inside tabs of a page control. These forms may contain actions with shortcuts. And I want these shortcuts to be fired only when the tab that contain this form is active. I tried to override form's IsShortCut but it's not called. Form's OnShortCut is not called either. I would like to avoid putting code on each action to check this. I'm using Delphi 2010.

  - by underline

  Hi, ok it is 'easy' to make jna wrapper solution for mapping exported functions within dll using jna: long f1(int x), just int long f2(char* y), just char[] but how to deal with long f3(char** z) ? I need f3's result(long) as well as z value on java side. Please don't say cpp code should be rewritten to avoid this:-)

• Load image from string

  - by zaf

  Given a string containing jpeg image data, is it possible to load this directly in pygame? I've tried using StringIO but failed and I don't completely understand the 'file-like' object concept. Currently, as a workaround, I'm saving to disk and then loading an image the standard way: # imagestring contains a jpeg f=open('test.jpg','wb') f.write(imagestring) f.close() image=pygame.image.load('test.jpg') Any suggestions on improving this so that we avoid creating a temp file?

• Are there any Spreadsheet apps that are as easy and powerful to use as Vim?

  - by ovatsug25

  I'd like to use a spreadsheet that lets me move around cells like I do in Vim. As well, the more commands that are attributed to keyboard shortcuts, the better. Particularly stuff like making Text-to-Columns which is one of my more frequently used features in Excel. I don't mind learning the shortcuts if they allow me to just look at the spreadsheet page and forget about everything else. edit: The way I am thinking about the Spreadsheet right now is as if every cell is its own unique file. There should be a command where I choose to open that file and edit it right on the spot within the view of the spreadsheet. So I guess I want different modes like in vim which have commands and there should be one mode that is hooked up just to do operations or formatting which would be similar to command mode in Vim.

• Python: how to calculate data received and send between two ipaddresses and ports [closed]

  - by ramdaz

  I guess it's socket programming. But I have never done socket programming expect for running the tutorial examples while learning Python. I need some more ideas to implement this. What I specifically need is to run a monitoring program of a server which will poll or listen to traffic being exchange from different IPs across different popular ports. For example, how do I get data received and sent through port 80 of 192.168.1.10 and 192.168.1.1 ( which is the gateway). I checked out a number of ready made tools like MRTG, Bwmon, Ntop etc but since we are looking at doing some specific pattern studies, we need to do data capturing within the program. Idea is to monitor some popular ports and do a study of network traffic across some periods and compare them with some other data. We would like to figure a way to do all this with Python....

• Recommended Offline Form Format

  - by Blithe

  Hi, I would like to ask for a recommendation on offline form format which user can bring around. Once done, they will upload the file to the server and data will be extracted from there. We are currently looking at Word and Excel 2003 since all users have it on their machine but it seems that using interops on server is something to avoid. Suggestions?

• When would JavaScript == make more sense than ===?

  - by bryantsai

  As 359494 indicates they are basically identical except '===' also ensures type equality and hence '==' might perform type conversion. In Douglas Crockford's JavaScript: The Good Parts, it is advised to always avoid '=='. However, I'm wondering what the original thought of designing two set of equality operators was. Have you seen any situation that using '==' actually is more suitable than using '==='?

• Where to store Android preference keys?

  - by pixel

  When I create preference activity I define all preferences in xml file. Every preference has a key defined in this xml. But when I access preference I write: SharedPreferences appPreferences = PreferenceManager.getDefaultSharedPreferences(this); boolean foo_value = appPreferences.getBoolean("foo_key_defined_in_xml", false); Is there any way to avoid acessing "foo_key_defined_in_xml" in hard-coded way? Maybe there is a possibility to access it in R style way?

• If I add a public method to a C# class, do I need to recompile other assemblies using that type?

  - by Adal

  Question in the title. I'd like to avoid recompiling since the source code I'm modifying is third party and I'd like to use the original binaries where possible, and replace only the assembly which contains the class I modified. But I'm not sure if this is a safe thing to do. In C++ for example this is definitely a bad idea.

• How do I add an Approver to SharePoint 2010?

  - by CompGeekess

  I am still new to SharePoint and am learning so much, but have came in to a few hic-ups and here is one. I want to add an approver to SharePoint 2010 who has FULL CONTROL. My manager requested that I find out where the approval request are going and redirect them to him. (I have no idea where or how to find this out). Is this possible to do on the Central Administration or must I go into each site/subsite and set him to be the approver this way? Googled and the site was showing me how to approve workflows or how to create approvals, my other resources didn't give much help either. So far I had gone into a few individual sites and set my manager and I up as approvers with full control, but am uncertain if this is the correct procedure or if there is a better way to do this. For example, have the lower levels inherit from the higher level - set security at the highest level and cascade to the child levels. Thank You.

• Trouble getting PHP, Apache, and Zend talking to eachother (localhost)

  - by Joel

  Hi guys, I've searched through several other questions, but haven't found my solution. THe main reason is that I'm not even sure if I have all these things properly installed. I have a hosting account, and have always just deployed everything into the internets, but I'm finally trying to figure out how to get my desktop set up right for learning Zend Framework. I have Apache Server 2.2, PHP, And Zend Framework installed. I'm trying to do this tutorial: http://akrabat.com/wp-content/uploads/Getting-Started-with-Zend-Framework.pdf The problem is when I click on the link: http://localhost/zf-tutorial/public I get an Error 404. If I type in http://www.localhost I get "It Works!" in the browser. I'm thinking this means I have Apache installed correctly, but am not pointing correctly to the Zend tutorial? Thanks for any help!

• HQL 'parsename' equivalent

  - by jaume

  I've discovered PARSENAME function as a good choice to order IP address stored in Database. Here there is an example. My issue is I'm using Hibernate with named queries in a xml mapping file and I am trying to avoid the use of session.createSQLQuery(..) function. I'm wondering if exists any PARSENAME equivalent function for HQL queries. I'm searching for it and cannot find anything. Many thanks.

• C: performance of assignments, binary operations, et cetera...

  - by Shinka

  I've heard many things about performance in C; casting is slow compared to normal assignments, functional call is slow, binary operation are much faster than normal operations, et cetera... I'm sure some of those things are specific to the architecture, and compiler optimization might make a huge difference, but I would like to see a chart to get a general idea what I should do and what I should avoid to write high-performance programs. Is there such a chart (or a website, a book, anything) ?

• Is there any analog of TCPvcon which allows to close TCP connection on remote machine?

  - by Miollnyr

  Hi, I started to use SysInternals suite, and it is great. But I wonder, whether there is any analog of TCPvcon, which allows to logon to remote machine, like psexec does, and then get list of TCP connections from there (similar to pslist functionality), and then to close some of connections (similar to pskill functionality). I am speaking about windows console tools and I would like to avoid installing something on remote machine is this is possible.

• How to modify existing keyboard layout (RU, kbdru.dll)?

  - by Anton

  There's a program I'm thinking of using called Punto Switcher that detects a language I'm typing in and switching entire word between Russian and English. The problem I have with this setup is that even though most of Russian letters "correspond" to English letters, Russian keys are scattered all over the keyboard and I don't feel like learning them all as I type in English mostly. Now, the program is very specific about me using RU, kbdru.dll file, not any other and if I use a custom keyboard under Russian, it doesn't recognize what I type so I think I should change the default RU keyboard. I created my custom keyboard using Microsoft's tool and I need to modify original one. I think it will take more than just replacing a file. Help?
