• How to deal with multiple screensizes + dynamic controls in Android?

  - by chobo2

  Hi I am learning how to program on Android phone. However I am unsure how to make my application work for the different screen sizes and resolutions. I read the tutorial on the android site and still unsure how to do it. First I know there are different files so could make a layout for each of the sizes but my problem is most of the screen needs to be dynamically created so there would not be much to put in these files. So I am not sure how to android to re size dynamic controls based on the screen size. I have also read it is bad practice to make controls in anything but the xml file as it separates view logic and programming logic. However they never talk about if you need to make these controls dynamically what you should do. So is there some other way to do it that is considered good practice?

• Getting content of a Facebook page in Adobe Flex

  - by cuneyt

  Hi guys, I wrote a Flex application that sends a UrlRequest to Facebook and gets the content of page as a string. The application user clicks a button, and the application connects to Facebook. And no I do not mean using Facebook API. It is like a screen scraper. This application worked locally, but when deployed to server it gives a sandbox security error. I have my crossdomain.xml on the root, but I think the problem is not that. Not only Facebook, but I cannot get any web site when the application is deployed on server. What should I do to get the content of a remote web page?

• How do I change the number of thumbnails seen in the Android sample Home application?

  - by Todd

  I am working with the sample Home application project on http://developer.android.com/resources/samples/Home/index.html I've added another value to the THUMBS_IDS and IMAGE_IDS Integer arrays in the Wallpaper class for a total of four wallpaper options. When I run the application with Device API version 7, Skin: HVGA, hw.lcd.density: 160, in portrait layout, the fourth wallpaper option is not shown. I need to use the directional keys in the emulator to see the 4th wallpaper option, because the first option is centered. I have modified only the wallpaper.xml file with a variety of android:layout_* options with no success at this point. How do I show all four of my wallpaper options?

• What are the requirements to consider someone as a Software Engineer? Is it just a job title? [close

  - by mike

  I am employed as a Software Engineer with a background in C# and .NET. I am trying to interface with an web API. I asked for help because I didn't know to connect to it or handle the results. Someone told me that I shouldn't consider myself a Software Engineer because I didn't know to how to do it. They said the API was well documented, required no authentication, and returned XML that I could easily parse. They said the documentation should be enough to figure out how to use the API. Isn't having a job title of Software Engineer the only consideration for being a Software Engineer?

• Is dynamic evaluation of xpath variable string possible using .net 2.0 xslt implementation?

  - by Crocked

  Hi, I'm trying to evaluate an xpath varable I'm building dynamically based on the position of the node. I can create the xpath string in a variable but when I select the value of this just get the string and not the node set I need. I use the following to create the xpath <xsl:variable name="xpathstring" select="normalize-space(concat(&quot;//anAttribute[@key='pos&quot;,position(),&quot;']&quot;))"/> and try to output the value with the following. <xsl:value-of select="$xpathstring"/> If I execute the xpath in my debugger I get the nodeset but in my xml output only get the xpath string which looks like this //anAttribute[@key='pos1'] I had a look at exslt dyn:evaluate which seems to enable this but this seems to be only supported by certain processors and doesn't provide a standalone implementation or at least as far as I could see (currently using the standard .net 2.0 xslt whihc is only xslt 1.0 as far as I recall) Is there anyway to handle this without changing processor? Kind Regards, Crocked

• Objective C: Can't find .js file in my mainBundle?!

  - by Nic Hubbard

  This is driving me crazy as I cannot figure out what in the world is going on. I load up files form you main bundle all the time, xml files, html files, etc. But, now I am trying to get the contents of a javascript file but it can never find it. I am using: NSData *jsData = [NSData dataWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"global" ofType:@"js"]]; if (jsData) { NSLog(@"%@", jsData); } else { NSLog(@"Can't find file"); return; } Even checking the [[NSBundle mainBundle] pathForResource:@"global" ofType:@"js"] string returns null. My activity.js file is in my Resources folder, the exact location where my other files are location that work totally fine using the above method. Why can't it find my js file?

• iPhone: Get value in multi-dimentional array

  - by Nic Hubbard

  I have an array that is many levels deep and I am wondering what is the best way to get one of the child element values that is deep in my array. I assume I need to use a recursive method, but what is the best way to do this? Or is there a faster way to do this? The array comes from an XML Parser that I am using which builds everything into an array like this (using NSLog to show the structure): { children = ( { children = ( { children = ( { children = ( ); data = 12; element = AssetID; } ); data = ""; element = "ns1:GetUserIdByUsernameResponse"; } ); data = ""; element = "SOAP-ENV:Body"; } ); data = ""; element = "SOAP-ENV:Envelope"; } What I would like to get at is the AssetID data, which in this case is 12.

• ImageView Force closes my application

  - by BlueFireLady

  Hi there I am really a beginner, and I have been fighting with this problem for 3 days. :( I am able to get an image to show using a grid view and an adapter as in the grid view tutorial, but I wanted to be able to just use ImageView in the xml. public class HelloImage extends Activity { public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); ImageView gridview = (ImageView) findViewById(R.id.gridview); gridview.setLayoutParams(new GridView.LayoutParams(85, 85)); gridview.setScaleType(ImageView.ScaleType.CENTER_CROP); gridview.setPadding(8, 8, 8, 8); gridview.setImageResource(R.drawable.hand_tool); } } When I run this it causes the app to force close when loading.

• C++ code generation for repeted task

  - by sateesh

  Hi, I have something like below which will get repeated many times based on the function that get called for e.g acceptfunction() { inserter["quantity"] = sdd.getfloat(quantity); inserter["prodtype"] = sdd.getstring(prodtype); : : so on } Like accept above there are 20 more functions(reject,cancel etc) which will do the similar thing.But the parameteres they insert can differ based on function called. How can I automate this kind of code.So that I dont need to write new function from scratch.Basically what I need is if i provide parametres like ("quantity",prodtype) through some text file or xml, it should generate the required function with the input parametres. Is this task can be handled through C++ tempalte Meta programming or someother code generation tool will help me to do this?

• vb express / visual studio - is it possible to run / debug one form only in a multi form application

  - by Luay

  hi, I have a vb application consisting of several winForms and code files. Is it possible to run / debug only one form without having to run the whole application? To be more specific, one of the forms in my application is the settings form where the user sets his/her desired options. These options are read/written to an xml file. Is it possible to debug just this one form (and not the whole program) to see if the reading/writing went well, if everything displayed correctly... ? If I am thinking the wrong way about this, could you point me in the right direction? By the way, I am using visual basic express / visual studio.

• Flash relationship map

  - by John

  Hi, Does anyone know any Flash fla's which are out there and free which do something similar to http://audiomap.tuneglue.net/ (you have to type in a search term to see it in action). What I'm after is the flash to create the node in the middle which expands out into children and then each of those children can be expanded out into more children, etc. while keeping their distance from one another so as to not overlap. I'd like it so that if you clicked on a node to expand it, it would shoot off to a web site and get an xml feed which could then be used to create the children. Thanks

• Which reporting tool would you recommend?

  - by grady

  Hi, I have some reporting functionality in my app and I want to improve it a bit. Its only SQL in a XML file which is read by some parser. There can be some params for that SQL and when its parsed and the params are injected, it is executed against my DB (SQL Server). I want to improve that a bit so that the results look better and are more flexible. This are the most important points I need to have: subtotals layout that can change dynamically according to settings in DB (like logo, slogan) possibility to use the same report template for several customers (same fields, but different logos,colors, slogans etc.) should run from an ASP.NET application It should be as dynamic as possible. I know of Crystal Reports and the Microsoft Reporting Tool. Are there any others that might be of interest and are my above points possible at all? Thanks for some ideas and hints :-)...

• How exactly can Python compliment your C# skills for windows based development?

  - by JL

  I'm looking for a fun challenge, and am thinking about learning Python. I've heard really good things about the language. My question is, how (if at all) can Python compliment the skills of a typical C# developer working mainly with MS technologies on a Windows Platform. Some examples of typical C# dev on windows would be (SOA applications, web applications, windows services, automation, xml handling) Surely there must be some scenarios where knowing Python would help you get certain tasks done quicker or more efficiently than using traditional C# / MS technologies. If you know of any specific scenarios, then please share. And lastly should this question be a community wiki?

• Hudson's FindBugs plugin reports line number "-1" for bugs. Ideas?

  - by John B.

  Greetings, I have a simple test project set up in Hudson and the project's build process (a batch file) generates a findbugs.xml file. This is processed by Hudson's FindBugs plugin but it shows the line number of the bugs as "-1" instead of their actual line number. A coworker suggested I enable debug info for the compiler. I used the -g "Generate all debugging info" option for javac but nothing seemed to change. My build command is: javac -g -classpath C:\testWebApp1\src -d C:\testWebApp1\build C:\testWebApp1\src\*.java The only other thing in the build.bat file is a call to the FindBug tool (text UI). Here is what the FindBugs Plugin says about the first bug: File: GenerateHellos.java, Line: -1, Type: UUF_UNUSED_FIELD, Priority: Normal, Category: PERFORMANCE Any ideas? Thanks a ton!

• [grails + xfire] How to handle errors in SOAP services?

  - by Mulone

  Hi all, I'm implementing a web service on the xfire plugin. I was wondering how I'm supposed to handle the errors. I tried with this setup but the error is not returned to the SOAP client: GaSession[] myMethod( String userId ) throws MyException{ GaUser user = GaUser.findByUserId( userId ) if (!user) throw new MyException("user ${userId} does not exist") // do stuff and return valid results } Is there a standard way to handle errors and return them to the client in a clear way? My log is full of messages like: 2010-06-13 18:20:40,926 [Thread-289] DEBUG aegis.XMLClassMetaInfoManager - Mapping file : /com/mycompany/MyClass.aegis.xml not found. Is there a way to fix this? Cheers!

• Localizing a JSF 1.2 application with UTF-8 resources

  - by Filini

  (WARNING: this is my first java application, coming from .NET, so don't bash me if I write too much garbage) I'm developing a simple JSF 1.2 web application which should support Russian, Chinese, and other languages outside ISO 8859-1, which is automatically used in Properties.load(). Is there a way to use the Properties loaded from XML files, with Properties.loadFromXml(), inside JSF, without writing too much code? I know there are alternative ways to do so (writing my own loader, escaping the characters...), but I'd really love to find a simple solution, and I don't see it in all the forums I checked. Thanks in advance for any help

• Authorization/Licensing of Webservice

  - by Burhan

  I have developed a web service which accepts the login credentials from the XML message passed to it. I have concerns over this method as the developer who consumes the service can easily share the login credentials and my service can be called from some other application that uses the same credentials. Is there any way that I can issue a 'license' to some specific applications? So that, even if credentials are shared among the consuming apps, only authorized ones can successfully consume the service. P.S: I thought about implementing IP restrictions but that doesn't serve the purpose as we may have different applications installed on a same server (we do have such a scenario implemented).

• Displaying conditional amount of fields in UI (Android)

  - by Sochin

  I am using layout xml documents for my ui controls. I need to create and remove these controls (input fields) on the fly, based on how many results I get back from my database. For each group, there can be 0..* fields and these are prepopulated from the database. Also, it would be good if I can invoke a method to create an additional field; something like the address book, where you can click + or - to add or remove a phone or other detail. In a "psuedo" style, I'm guessing something like this: Check database - How many of X are there [y]? Create Y fields. The user may then add new fields, so once I click submit i need to apply all of that to database. Any examples or hints greatly welcomed. Hope this make sense! :)

• Take advantage of multiple cores executing SQL statements

  - by willvv

  I have a small application that reads XML files and inserts the information on a SQL DB. There are ~ 300 000 files to import, each one with ~ 1000 records. I started the application on 20% of the files and it has been running for 18 hours now, I hope I can improve this time for the rest of the files. I'm not using a multi-thread approach, but since the computer I'm running the process on has 4 cores I was thinking on doing it to get some improvement on the performance (although I guess the main problem is the I/O and not only the processing). I was thinking on using the BeginExecutingNonQuery() method on the SqlCommand object I create for each insertion, but I don't know if I should limit the max amount of simultaneous threads (nor I know how to do it). What's your advice to get the best CPU utilization? Thanks
