• RSA Encrypt in PHP to decrypt in .NET

  - by user312904

  In PHP I am RSA encrypting a message to be decrypted by .NET application... but I keep getting a "Bad Key" exception from .NET.... For RSA encryption, I am using PEAR class Crypt_RSA- encrypting with the public key (which is a modulus, exponent pair) I get from working encryption system in .NET... I guess the easiest question would be- does "Bad Key" mean it is not able to decrypt the message whatsoever? IE, it is not encrypted correctly? The harder question is- Is there anything specific about RSA encryption that causes quirks between .NET and PHP?

• Using Python's ConfigParser to read a file without section name

  - by Arrieta

  Hello: I am using ConfigParser to read the runtime configuration of a script. I would like to have the flexibility of not providing a section name (there are scripts which are simple enough; they don't need a 'section'). ConfigParser will throw the NoSectionError exception, and will not accept the file. How can I make ConfigParser simply retrieve the (key, value) tuples of a config file without section names? For instance: key1=val1 key2:val2 I would rather not write to the config file.

• [Java] - Problem having my main thread sleeping

  - by Chris

  I'm in a Java class and our assignment is to let us explore threads in Java. So far so good except for this one this one problem. And I believe that could be because of my lack of understanding how Java threads work at the moment. I have the main thread of execution which spawns new threads. In the main thread of execution in main() I am calling Thread.sleep(). When I do I get an Unhandled exception type InterruptedException. I am unsure of why I am getting this? I thought this was because I needed a reference to the main thread so I went ahead and made a reference to it via Thread.currentThread(). Is this not the way to have the thread sleep? What I need to do is have the main thread wait/sleep/delay till it does it required work again. Any help would be much appreciated.

• How to enable i18n from within setup_app in websetup.py ?

  - by daniel

  From within the setup_app function (websetup.py) of a pylons i18n application, which is making use of a db, I was trying to initiate multilingual content to be inserted into the db. To do so the idea was something like: necessary imports here def setup_app(command, conf, vars): .... for lang in langs: set_lang(lang) content=model.Content() content.content=_('content') Session.add(content) Session.commit() Unfortunately it seems that it doesn't work. the set_lang code line is firing an exception as follows: File ".. i18n/translation.py", line 179, in set_lang translator = _get_translator(lang, **kwargs) File ".. i18n/translation.py", line 160, in _get_translator localedir = os.path.join(rootdir, 'i18n') File ".. /posixpath.py", line 67, in join elif path == '' or path.endswith('/'): AttributeError: 'NoneType' object has no attribute 'endswith' Actually I'm even not sure it could be possible launching i18n mechanisms from within this setup_app function without an active request object. Anyone has tried some trick on a similar story ?

• selectors-api for data attributes

  - by MJ

  In HTML5, CSS selectors seem to operate well with data-* attributes. For example: <style> div[data-foo='bar'] { background:#eee; } </style> <div data-foo='bar'>colored</div> <div>not colored</div> will properly style the first . But, attempts to select such elements using the selectors-api fail. Examples: var foos = document.querySelectorAll("div[data-foo]='bar'"); or var foos = document.querySelectorAll("div data-foo='bar'"); in Chrome and Safari, this produces a cryptic error: SYNTAX_ERR: DOM Exception 12 Any thoughts on how to use the selectors-api to properly select elements on the basis of data-* attributes?

• Prevent Visual Studio Web Test from changing request details

  - by keithwarren7

  I have a service that accepts Xmla queries for Analysis services, often times those queries themselves will have a string that contains a fragment that looks something like {{[Time].[Year].[All]}} Recording these requests works fine but when I try to re-run the test I get an error from the test runner... Request failed: Exception occurred: There is no context parameter with the name ' [Time].[Year].[All]' in the WebTestContext This was confusing for some time but when I asked VS to generate a coded version of the test I was able to see the problem a bit better. VS searches for the '{{' and '}}' tokens and makes changes, considering those areas to refer to Context parameters, the code looks like this.Context["\n\t[Time].[Year].[All]"].ToString() Anyone know how to instruct Visual Studio to not perform this replacement operation? Or another way around this issue?

• Watir::IE.attach(:title,/x/) not working correctly on Win 7 IE8

  - by Zachary Hayes

  System: Window 7 Internet Explorer 8 Ruby 1.8 Watir 1.6.5 If I manually open a browser window and then visit a site that causes a second browser window to open and then use the Watir::IE.attach method to find the second browser window everything work fine. The problem is when I open the first Internet Explorer window with the command Watir::IE.new and then visit a site that causes a second browser window to open. When I use Watir::IE.attach to find the second browser window I now get: Watir::Exception::NoMatchingWindowFoundException: Unable to location a window with title of (?-mix:x) from /ie-class.rb:297:in 'attach_browser_window' from /ie-class.rb:149:in '_attach_init' from /ie-class.rb:143:in 'attach' from (irb):15 Has anyone run into this problem and developed a solution?

• Problem updating blog with hibernate?

  - by johnsmith51

  hi, i am having problem updating a blob with hibernate. my model have these getters/setters for hibernate, i.e. internally i deal with byte[] so any getter/setter convert the byte[] to blog. I can create an initial object without problem, but if I try to change the content of the blob, the database column is not updated. I do not get any error message, everything looks fine, except that the database is not updated. /** do not use, for hibernate only */ public Blob getLogoBinaryBlob() { if(logoBinary == null){ return null; } return Hibernate.createBlob(logoBinary); } /** do not use, for hibernate only */ public void setLogoBinaryBlob(Blob logoBinaryBlob) { ByteArrayOutputStream baos = new ByteArrayOutputStream(); try { logoBinary = toByteArrayImpl(logoBinaryBlob, baos); } catch (Exception e) { } }

• cakephp - try/catch an Action

  - by joshs

  I would like to somehow apply a try catch statement to all Actions as a backstop for any uncaught exceptions. I think this would be particularly helpful for Ajax Actions, because the catch statement could send back a default 4xx status code. Prototype's onFailure() function could then do the client-side error handling. How can I do this without wrapping the Action call with a try/catch in the cake dispatcher like this: try { output = $controller->dispatchMethod($params['action'], $params['pass']); } catch {...} Does anybody have a suggestion or another workable strategy for gaining this functionality without touching the dispatcher? How do people feel about putting exception handling in the Displatcher? I imagine when cake drops php 4 support, there will be a built-in mechanism for this.

• (C#) graphics.drawImage has a size limit? How to deal with it?

  - by DGH

  I am attempting to display a very large graphical representation of some data. I am using a bitmap for persistent storage of the image and e.Graphics.DrawImage(myBitmap, new Point(0,0)) in the onPaint of a PictureBox control on my form. I have noticed (and heard mentioned on other sites) that if my image has a height or width greater than 2^15, I get a Parameter not Valid exception, but I have not found any official documentation of this limit. Is this 2^15 image size limit a definite, official part of Graphics.DrawImage? Are there any simple workarounds to render my entire image onto the form? (Yes, the pictureBox is set to the same size as the image, or bigger. Side question though, should I just be using the onPaint of the form itself instead of a picture box?)

• Albacore msbuild task problem

  - by Dejan

  Just updated albacore to version 0.14 and ran into a major problem. My current environment is: Ruby 1.9.1 Rake 0.8.7 Albacore 0.1.4 The problem is that as of now all my rake build throw a funny little exception: undefined method 'push' for #<Enumerator:0x???????> So far I have traced the problem to albacore msbuild.rb line 38 and 26. To be honest I just don't have a clue why this is happening. As a little help here is the rake task that is turning my hear Grey :) desc "Build solution" msbuild :build => :prepareOutput do |msb| msb.properties :configuration => :Release msb.targets :Clean, :Build msb.solution = "../xxx/xxx/xxx.sln" end

• Showing a Toast using "setUncaughtExceptionHandler"

  - by VitalyB

  Hi everyone, I'm trying to do a simple global exception handler in my Android app and I am having troubles: public class TicTacToe extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); Thread.currentThread().setUncaughtExceptionHandler(new UncaughtExceptionHandler() { @Override public void uncaughtException(Thread thread, Throwable ex) { Toast.makeText(this, "TOAST", Toast.LENGTH_LONG); } }); setContentView(R.layout.main); } } I'm a rather new with both Android AND java but in .NET that would work. Can't I access local variable from anonymous methods in java? If so, how should I rewrite it? Thanks, Vitaly

• Allow single-line accessor (getter/setter) syntax with Checkstyle

  - by Sam3

  We'd like to have trivial Java property accessors using a single line syntax, so they take up much much less space, and are more readable (in terms of 'seeing' the set of accessors quickly). But we do want to enforce multi-line method syntax for everything else in our checkstyle configuration. But I'm not sure how to make this exception for accessors in Checkstyle config and suspect it may not be possible. So we'd like our accessors to look something like this: public String getFoo() { return foo; } public void setFoo(String foo) { this.foo = foo; } [In fact we'd rather not have trivial accessors at all and instead just annotate the private member variables with @Property or something and have the accessors generated for us, since writing endless get and set code delivers no real benefit, but that's a general Java frustration and an aside as far as this question goes.]

• Creating SQL Server index on a nvarchar column

  - by Jahan

  When I run this SQL statement: CREATE UNIQUE INDEX WordsIndex ON Words (Word ASC); I get the following exception message: The CREATE UNIQUE INDEX statement terminated because a duplicate key was found for the object name 'dbo.Words' and the index name 'WordsIndex'. The duplicate key value is (ass). The statement has been terminated. The 'Word' column has a datatype of nvarchar(100). There are two items in the 'Word' column that SQL Server interprets as the same: 'aß' and 'ass', which causes the indexing failure. Why would SQL Server interpret those two different words as the same word?

• Does JavaME and/or Proguard reorder assignments?

  - by chrisdew

  This is a simplified example - I have two threads: Can JavaME and/Proguard ever reorder the obX = ... statements, such that thread_B will have a null pointer exception at ob2.someMethod? thread_A: Object ob1 = null; Object ob2 = null; ... ob1 = something1; ob2 = something2; thread_B: if (ob2 != null) { ob1.someMethod(); ... } P.S. I do realise that synchronising these will avoid the issue. Synchronisation has both a performance overhead, and more importantly, a chance to introduce deadlock.

• jQuery 1.4.x and the @ symbol

  I used to use this script for jquery email obfuscation: $(".replaceAt").replaceWith("@"); $(".obfuscate").each(function () { $(this).attr("href", "mailto:"+$(this).text()); }); <a class="obfuscate">name<span class="replaceAt">-AT-</span>server.com</a> But with jQuery 1.4.x, I now get this error: uncaught exception: Syntax error, unrecognized expression: @ Looking this up on the net, it looks like jQuery thinks that the @ is a special character. I tried to "\@" it and a few other things with not luck. I'm not enough of a jQuery ninja to know how to fix this. Any ideas?

• Django admin interface upload failing on request data read error

  - by Jake

  Hi All, This is an updated version of an old question I asked. I've now done a lot more testing, plus the old question got hijacked. I'm getting a request data read error when trying to upload files to the Django admin interface. Files under about 150k work, but bigger files always fail and almost always at around 192k (that's 3 chunks) completed, sometimes at around 160k. The Exception I get is below. File "/usr/lib/python2.4/site-packages/django/http/multipartparser.py", line 405, in read return self._file.read(num_bytes) IOError: request data read error I've tried Chrome and Firefox on Windows and Firefox on Mac - Same results. I can upload to other sites so I don't think it's my connection. I'm running python 2.4, django 1.1, mod_wsgi, on CentOS (a media temple DV server) Locally it's fine (Django development server) Everything I've found on this issue says it's a mod_python issue and that changing to mod_wsgi will fix it, but I am running mod_wsgi. Can anyone help?

• Interpretation of Greek characters by FOP

  - by Geek

  Hi, Can you please help me interpret the Greek Characters with HTML display as HTML= & #8062; and Hex value 01F7E Details of these characters can be found on the below URL http://www.isthisthingon.org/unicode/index.php?page=01&subpage=F&hilite=01F7E When I run this character in Apache FOP, they give me an ArrayIndexOut of Bounds Exception Caused by: java.lang.ArrayIndexOutOfBoundsException: -1 at org.apache.fop.text.linebreak.LineBreakUtils.getLineBreakPairProperty(LineBreakUtils.java:668) at org.apache.fop.text.linebreak.LineBreakStatus.nextChar(LineBreakStatus.java:117) When I looked into the FOP Code, I was unable to understand the need for lineBreakProperties[][] Array in LineBreakUtils.java. I also noticed that FOP fails for all the Greek characters mentioned on the above page which are non-displayable with the similar error. What are these special characters ? Why is their no display for these characters are these Line Breaks or TAB’s ? Has anyone solved a similar issue with FOP ?

• FreeLibrary vs implicit unloading DLL

  - by Adil

  I have implemented a DLL including DllMain() entry function:- BOOL APIENTRY DllMain( HMODULE hModule, DWORD ul_reason_for_call, LPVOID lpReserved ) { case DLL_PROCESS_ATTACH: ... case DLL_THREAD_ATTACH: ... case DLL_THREAD_DETACH: ... case DLL_PROCESS_DETACH: ... } Unfortunately i made a mistake in DLL_PROCESS_DETACH case and accessing illegal memorey (access violation). I made a sample program which loads the library using LoadLibrary() function, uses the library function and finally call FreeLibrary() and return. When i executed this program, i didnt get any error message. But if i remove FreeLibrary(), in that case the DLL_PROCESS_DETACH case is executed implicitly and this time it gives error dialog box mentioning that there is access violation. Why calling FreeLibrary() suppress this error? OR internally it handles this exception? What is suggested way.

• "The provider is not compatible with the version of Oracle client"

  - by psyb0rg

  I just put my asp .net web service on a remote host. The service accesses an oracle db on my local machine. The service worked fine when it was running on localhost but since moving to a remote hos, I get The provider is not compatible with the version of Oracle client at Oracle.DataAccess.Client.OracleInit.Initialize() at Oracle.DataAccess.Client.OracleConnection..cctor() --- End of inner exception stack trace --- at Oracle.DataAccess.Client.OracleConnection..ctor(String connectionString) at.... I know the error is related to the data provider version running on the server/client. In my case, the only dll I referenced in the project was Oracle.DataAccess So how do I go about solving this? Note that I won't be able to change anything on the web host other than my own project. My local machine is running Oracle 11g Thanks.

• problem with null column

  - by Iulian

  One column in my database (of type double) has some null values. I am executing a sored procedure to get the data in my app wipDBTableAdapters.XLSFacturiTableAdapter TAFacturi = new wipDBTableAdapters.XLSFacturiTableAdapter(); var dtfacturi = TAFacturi.GetData(CodProiect); Then i try to do something like this: if (dtfacturi[i].CANTITATE == null) { //do something } this is giving a warning : The result of the expression is always 'false' since a value of type 'double' is never equal to 'null' of type 'double? However when i run my code i get the following exception: StrongTypingException The value for column 'CANTITATE' in table 'XLSFacturi' is DBNull. How am I supposed to resolve this ?

• Nullables? Detecting them

  - by Aren B

  Ok, im still a bit new to using nullable types. I'm writing a reflecting object walker for a project of mine, im getting to the point where im setting the value of a reflected property with the value i've retrieved from a reflected property. The value i've retrieved is still in object form, and it dawned on me, since i want my object walker to return null when it can't find something, (I thought about throwing an exception, but i want this to soft-fail when something's wrong). Anyway, some of the values im setting/getting are decimal bool etc... so it dawned on me that i should just NOT set a non-nullable value, but I realized I straight up don't know how to tell decimal from decimal? Is it enough to key on if the Type of the property im setting is inherited from ValueType?
