• Android list all images available

  - by Javadid

  hi friends, I m making an application which requires me to list all the images available on the SD-Card of the phone. i tried querying the ContentResolver way i.e. Cursor image = getContentResolver().query(Images.Media.EXTERNAL_CONTENT_URI, new String[]{Images.Media._ID,Images.Media.DATA,Images.Media.DISPLAY_NAME}, null, null, null); but without any result. Is there any way i can get the list or if thats not possible then is there any possible intent (e.g. PICK) by which i can allow the user to select a file and then access the path of the file the user selected?? Helppppp guys...

• How to create wordpress-like option table and get values for each row?

  - by Nacho

  Hi guys. I'm looking to create an options table in my db that makes every record a system option, so I can work with a little number of fields. My db has the following structure: 3 columns named id, name, and value The following data is inserted as an example: +--+-----------+--------------------------+ |id|name |value | +--+-----------+--------------------------+ | 1|uri |www.example.com | | 2|sitename |Working it out | | 3|base_folder|/folder1/folder2/ | | 4|slogan |Just a slogan for the site| +--+-----------+--------------------------+ That way I can include a large number of customizable system options very easily. The problem is that I don't know how to retrieve them. How do I get the value of uri and store it as a var? And better yet, how do I get, for exmaple, values of id 1 and 4 only without making a query each time? (I assume multiple queries are useless and a pretty ugly method.) I know the question is pretty basic but I'm lost here. I'd really appreciate your answer!

• AS3 / Java - Socket Connection from live Flash to local java

  - by PitchBlackCat

  Hey guys, I'm trying to get a live flash that lives on a webserver to talk to a local java server, that will live on the clients PC. I'm trying to achieve this with a socket connection. (port 6000) Now, at first flash was able to connect, but it just sends <policy-file-request/>. After this nothing happens. Now, some people at Kirupa suggested to send an cross-domain-policy xml as soon as any connection is established from the java side. http://www.kirupa.com/forum/showthread.php?t=301625 However, my java server just throws the following: End Exception: java.net.SocketException: Software caused connection abort: recv failed I've already spend a great amount of time on this subject, and was wondering if anyone here knows what to do?

• Reuse C++ Header files

  - by Amrish

  Guys, I have a Visual C++ solution with 2 projects AlgorithmA & AlgorithmB and both share a common header file RunAlgo.h with the class declaration. Each project in the solution has its own unique implementation for the header file. I am trying to compile a DLL out of the common header file RunAlgo.h and add reference to this DLL in the projects AlgorithmA & AlgorithmB. I have then included separate RunAlgo.cpp definition file in both my projects. The problem is that I am getting linker errors while compiling the new DLL project which has only the header file. So, the question is Can a header file with only class declaration be compiled into a DLL (Similar to class library containing an Interface in C#)? For the above scenario, is there a better approach to reuse the common Header file among projects? Should the above method work (re-check my code?)

  Hi, guys. This is a VBS script that opens google, fills a form, and clicks a search button. set ie = CreateObject("InternetExplorer.Application") ie.navigate("www.google.com") ie.visible = true while ie.readystate <> 4 wscript.sleep 100 WEnd set fields = ie.document.getelementsbyname("q") set buttons = ie.document.getelementsbyname("btnG") fields(0).value = "some query" buttons(0).click ie.quit Sub OnClickSub() MsgBox "button clicked!", 0 End Sub Obviously, buttons(0).click fires an onclick event of the button, which I somehow need to catch in my script, and provide it with some processing like launching OnClickSub().

• Drupal CCK Text field not saving.

  - by Mark Milbourne

  Hey Guys, I've been trying to write a CCK Field based on the Text field. But if I create a standard CCK Text field with only 1 value. Then edit a content item for this type, the values are never persisted. When I go back in and edit the same node, the value isn't there. I checked the database and its not in the table for the CCK node. If I use more than one value it works fine. I'm upto date on CCK (6.x-2.6) and CTools (6.x-1.5). Has anyone seen this? and a possible solution?

• Is it possible to implement Flex states in Android application.

  - by barmaleikin

  Hi guys, Let me explain what I am want to archive. For example, in Flex I can create page (list of something) with 3 states: Loading state (just display some animation or label with text "Please wait."), No records state (page with text saying that there is no records) and Page with populated list. It is very easy to operate with states in Flex. Is it possible to implement something similar in Android application? I would appreciate if you provide some examples.

  - by Alan Bennett

  hi guys, I have a recuring method which shows up many times in my code its basically checking to make sure that the connection to the odbc is ok and then connects but each time this method is called it calls another method and each instance of the main method this one is different, as each method is about 8 lines of code having it 8 times in the code isnt ideal. so basically i would like to have just one method which i can call passing the name of the new method as an arguement. so basically like: private void doSomething(methodToBeCalled) { if(somthingistrue) { methodToBeCalled(someArgument) } } is this possible? thanks in advance

This cols all shall fill half of the screen in width. Can someone give me a hint?

• Rails - undefined method `name' for nil:NilClass

  - by sscirrus

  Hi guys, Quick question. Here is my code: #routes map.resources :customers, :has_many => [:addresses, :matchings] map.connect ":controller/:action/:id" #url path: http://127.0.0.1:3000/customers/index/3 #customers controller def index @customer = Customer.find(params[:id]) end #customers view/index.html.erb ... <%= @customer.name %> ... Error: undefined method `name' for nil:NilClass. Here's my reasoning. The parameter :id is coming from my url path (i.e. we're looking for customer #3 in the above path). @customer should find that array easily, then @customer.name should produce the name, but apparently @customer is blank. Why? I assume the problem is that I'm not producing an array in my controller?

• Size of assosiation in Hibernate criteria.

  - by trnl

  Hello guys. I've faced with a problem when querying with Hibernate Criteria in Grails. Take a look: def visitors = Client.withCriteria{ visits{ use ( TimeCategory ) {between('date',date,date+1.month-1)} } sizeGe("visits",params.from) sizeLe("visits",params.to) fetchMode("visits", FM.JOIN) }; I need only those clients, which has number of visits in month between from and to bounds. But now size* restrictions is being applied to all visits. So if client has one visit in this month, and visit in previous month. And if I set from=2, this client will be in result. But it should not be there. Any help is appreciated. Thanks, Vova.

• Predicates and Lists

  - by George

  Hello guys, I have a generic list. Some elements of this list belong to a parent element. I retrieved all these elements from a database and i want to recursively build a tree with them. So, here's what i'm thinking: Here is my predicate: public static bool FindChildren(Int32 parentId,CategoryMapping catMapping) { if (catMapping.parentId == parentId) { return true; } else { return false; } } root = list[0]; root.childrenElements = root.FindAll(FindChildren(root.id,???) I can't figure out how this would work. How can i do this kind of predicate?
