  • How should I re-raise a Delphi exception after logging it?

    - by Nik
    Do you know a way to trap, log, and re-raise exception in Delphi code? A simple example: procedure TForm3.Button1Click(Sender: TObject); begin try raise Exception.Create('Bum'); except on E: Exception do begin MyHandleException(E); end; end; end; procedure TForm3.MyHandleException(AException: Exception); begin ShowMessage(AException.Message); LogThis(AException.Message); // raise AException; - this will access violate end; So I need to re-raise it in the except block but I was wondering if there is a better way to write my own method to handle and (on specific conditions) to re-raise exceptions.

  • Uses for the capacity value of a string

    - by dreamlax
    In the C++ Standard Library, std::string has a public member function capacity() which returns the size of the internal allocated storage, a value greater than or equal to the number of characters in the string (according to here). What can this value be used for? Does it have something to do with custom allocators?

  • BizTalk - generating schema from Oracle stored proc with table variable argument

    - by Ron Savage
    I'm trying to set up a simple example project in BizTalk that gets changes made to a table in a SQL Server db and updates a copy of that table in an Oracle db. On the SQL Server side, I have a stored proc named GetItemChanges() that returns a variable number of records. On the Oracle side, I have a stored proc named Update_Item_Region_Table() designed to take a table of records as a parameter so that it can process all the records returned from GetItemChanges() in one call. It is defined like this: create or replace type itemrec is OBJECT ( UPC VARCHAR2(15), REGION VARCHAR2(5), LONG_DESCRIPTION VARCHAR2(50), POS_DESCRIPTION VARCHAR2(30), POS_DEPT VARCHAR2(5), ITEM_SIZE VARCHAR2(10), ITEM_UOM VARCHAR2(5), BRAND VARCHAR2(10), ITEM_STATUS VARCHAR2(5), TIME_STAMP VARCHAR2(20), COSTEDBYWEIGHT INTEGER ); create or replace type tbl_of_rec is table of itemrec; create or replace PROCEDURE Update_Item_Region_table ( Item_Data tbl_of_rec ) IS errcode integer; errmsg varchar2(4000); BEGIN for recIndex in 1 .. Item_Data.COUNT loop update FL_ITEM_REGION_TEST set Region = Item_Data(recIndex).Region, Long_description = Item_Data(recIndex).Long_description, Pos_Description = Item_Data(recIndex).Pos_description, Pos_Dept = Item_Data(recIndex).Pos_dept, Item_Size = Item_Data(recIndex).Item_Size, Item_Uom = Item_Data(recIndex).Item_Uom, Brand = Item_Data(recIndex).Brand, Item_Status = Item_Data(recIndex).Item_Status, Timestamp = to_date(Item_Data(recIndex).Time_stamp, 'yyyy-mm-dd HH24:mi:ss'), CostedByWeight = Item_Data(recIndex).CostedByWeight where UPC = Item_Data(recIndex).UPC; log_message(Item_Data(recIndex).Region, '', 'Updated item ' || Item_Data(recIndex).UPC || '.'); end loop; EXCEPTION WHEN OTHERS THEN errcode := SQLCODE(); errmsg := SQLERRM(); log_message('CE', '', 'Error in Update_Item_Region_table(): Code [' || errcode || '], Msg [' || errmsg || '] ...'); END; In my BizTalk project I generate the schemas and binding information for both stored procedures. For the Oracle procedure, I specified a path for the GeneratedUserTypesAssemblyFilePath parameter to generate a DLL to contain the definition of the data types. In the Send Port on the server, I put the path to that Types DLL in the UserAssembliesLoadPath parameter. I created a map to translate the GetItemChanges() schema to the Update_Item_Region_Table() schema. When I run it the data is extracted and transformed fine but causes an exception trying to pass the data to the Oracle proc: *The adapter failed to transmit message going to send port "WcfSendPort_OracleDBBinding_HOST_DATA_Procedure_Custom" with URL "oracledb://dvotst/". It will be retransmitted after the retry interval specified for this Send Port. Details:"System.InvalidOperationException: Custom type mapping for 'HOST_DATA.TBL_OF_REC' is not specified or is invalid.* So it is apparently not getting the information about the custom data type TBL_OF_REC into the Types DLL. Any tips on how to make this work?

  • Java: Is there a way to obtain the bytecode for a class at runtime?

    - by Adam Paynter
    In Java, is there a way (at runtime) to obtain the bytecode which defined a particular class? Put another way, is there a way to obtain the byte[] array passed to ClassLoader.defineClass(String name, byte[] b, int off, int len) when a particular class was loaded? I see that this method is declared final, so creating a custom ClassLoader to intercept class definitions seems out of the question. In the past, I have used the class's ClassLoader to obtain the bytecode via the getResourceAsStream(String) method, but I would prefer a more canonical solution.

  • Create an UIButton with "push button" appearance?

    - by Krumelur
    I want to create a button with the same look and feel as the "Timer" function in the builtin Clock app, but it really eludes me how to do it. By looking at the source code for UICatalog, it seems to create these buttons you need to create a custom bitmap. Is this true? If so, is there a "standard" bitmap that can be used, to ensure consistent user experience?

  • Online graphing and data visualization frameworks

    - by Marques
    I have been looking around at web applications and websites with rich graphs, charts, and data visualization and for the most part have been able to determine which frameworks or tools websites are using. However I was looking over 'resumup.com' and couldn't determine what they are using. Does anyone know off hand or can you tell? It doesn't seem like any javascript framework i've seen unless its custom...is it some sort of flash or flex framework? Any help would be greatly appreciated. Thanks, Marques

  • How do I run JUnit tests from inside my java application?

    - by corgrath
    Is it possible to run JUnit tests from inside my java application? Are there test frameworks I can use (such as JUnit.jar?), or am I force to find the test files, invoke the methods and track the exceptions myself? The reason why I am asking is my application requires a lot of work to start launch (lots of dependencies and configurations, etc) and using an external testing tool (like JUnit Ant task) would require a lot of work to set up. It is easier to start the application and then inside the application run my tests. Is there an easy test framework that runs tests and output results from inside a java application or am I forced to write my own framework?

  • Thoughts on try-catch blocks

    - by John Boker
    What are your thoughts on code that looks like this: public void doSomething() { try { // actual code goes here } catch (Exception ex) { throw; } } The problem I see is the actual error is not handled, just throwing the exception in a different place. I find it more difficult to debug because i don't get a line number where the actual problem is. So my question is why would this be good? ---- EDIT ---- From the answers it looks like most people are saying it's pointless to do this with no custom or specific exceptions being caught. That's what i wanted comments on, when no specific exception is being caught. I can see the point of actually doing something with a caught exception, just not the way this code is.

  • jms message not moving of the queue in websphere

    - by user271858
    I have a message driven bean that throws exception under certain conditions. When it throws an exception the message is not processed and put back on the queue. From what I understand with MQ and WAS (Websphere Application Server) the message should be marked as bad after x number of tries and removed from the queue. This is not happening and the message remains on the queue marked as bad. What part of the configuration in MQ and/or WAS have I missed to set correct? (The issue with the MDB throwing exceptions is NOT the point here) Thanks.

    got the jq cycle plugin to work nicely on all the other major browsers, but IE7 just shows the first nested element (an img with a anchor wrapped around it) with no fade/animation. http://alitedesigns.com/ I checked for trailing commas after the custom attributes for cycle, any thoughts on why IE won't play nice? thanks!

  • Converting an empty string into nil in Ruby

    - by adi92
    I have a string called word and a function called infinitive such that word.infinitive would return another string on some occasions and an empty string otherwise I am trying to find an elegant ruby one line expression for the code-snippet below if word.infinitive == "" return word else return word.infinitive Had infinitive returned nil instead of "", I could have done something like (word.infinitive or word) But since it does not, I can't take advantage of the short-circuit OR Ideally I would want 1) a single expression that I could easily embed in other code 2) the function infinitive being called only once 3) to not add any custom gems or plugins into my code

  • Create and display indoor map on Android

    - by Lorenzo Barbagli
    I'm developing an Android application and I would like to display an internal (indoor) map of some buildings, but I don't know where to begin: I want to create a custom kml file (how it's possible to create it? with which tool?) and display it in a fragment. I already have it working with external maps (simple GoogleMap in MapFragment), so it would be super to have the kml file placed 'over' the GoogleMap, like real indoor maps. Thanks
