  • Macros in macros (C++)

    - by meds
    Is it possible to put a macro in a macro in c++? Something like: #define Something\ #ifdef SomethingElse\ //do stuff \ #endif\ I tried and it didn't work so my guess is it doesn't work, unless there's some sort of syntax that can fix it?

  • Fast file search algorithm for IP addresses

    - by Dave Jarvis
    Question What is the fastest way to find if an IP address exists in a file that contains IP addresses sorted as: 219.93.88.62 219.94.181.87 219.94.193.96 220.1.72.201 220.110.162.50 220.126.52.187 220.126.52.247 Constraints No database (e.g., MySQL, PostgreSQL, Oracle, etc.). Infrequent pre-processing is allowed (see possibilities section) Would be nice not to have to load the file each query (131Kb) Uses under 5 megabytes of disk space File Details One IP address per line 9500+ lines Possible Solutions Create a directory hierarchy (radix tree?) then use is_dir() (sadly, this uses 87 megabytes)

  • iPhone dev on Linux

    - by Daziplqa
    Hi guyz, Actually I have read about that I can write Objective-C app on Linux (using GNUStep). But my question is, Am I will be able to develop completely iPhone app on Linux machine? Or I'll need eventually need to use Mac machine? Especially when I read that there are some some syntax diffs between NeXT/Apple and GCC (according to http://en.wikipedia.org/wiki/Objective-C)

  • Python ttk.Button -command, runs without button being pressed

    - by Markus Kothe
    I'm making a small script in python with ttk and I have a problem where a function runs where it shouldn't. The button code looks as follows: btReload = ttk.Button(treeBottomUI, text="Reload", width=17, command=loadModelTree(treeModel)) btReload.pack(side="left") and the function is as this: def loadModelTree(tree): print ("Loading models...") allModels = os.listdir(confModPath) for chunk in allModels: ... For some reason, the function runs without the button being pressed. Why?

  • GWT Button eventlistener designer

    - by msaif
    For example I took html from a designer which is given below. How can i add click event which shows alert from GWT? final Button button = new Button("OK"); I dont allow to add button dynamically from GWT by RootPanel.get("sendButtonContainer").add(button); I am searching the syntax something like: RootPanel.get("sendButtonContainer").getWidget(0).addEventListener()??????? Jquery can search the button object from nameFieldContainer and dynamically add click event listener but is it possible in GWT??

  • Drawing a text in OnRender method

    - by Eden
    I have a class which inherits from Canvas. On the OnRender method I draw a text which is being covered by the controls that are on the canvas. Is there a method to place the text "above" the controls? is there an OnRenderComplete method (that is being called after the visual tree was rendered)?

  • Linq 2 Sybase ASE database? What are the options?

    - by Scott Weinstein
    I have a need to query an existing Sybase ASE database and would like to use Linq syntax for my data retrival. I don't need write access, nor do I need the full set of Linq operators, just Select(), SelectMany(), Where(), and GroupJoin() What are options are available? In particular, I'm wondering about nHibernate and building a new Linq2Sybase provider based on the IQ toolkit.

  • How to read unix usage

    - by sixtyfootersdude
    I did some searching but I cannot find documentation on how unix usage works. I know somethings (mostly through trial and error) but for example how do I know that: /usr/bin/ls [-aAbcCdeEfFghHilLmnopqrRstuvVx1@] [file]... Means that you can include more than one option. Ie: ls -la Can someone point me to some documentation on what the usage syntax is.

  • Efficiency of Java "Double Brace Initialization"?

    - by Jim Ferrans
    In Hidden Features of Java the top answer mentions Double Brace Initialization, with a very enticing syntax: Set<String> flavors = new HashSet<String>() {{ add("vanilla"); add("strawberry"); add("chocolate"); add("butter pecan"); }}; This idiom creates an anonymous inner class with just an instance initializer in it, which "can use any [...] methods in the containing scope". Main question: Is this as inefficient as it sounds? Should its use be limited to one-off initializations? (And of course showing off!) Second question: The new HashSet must be the "this" used in the instance initializer ... can anyone shed light on the mechanism? Third question: Is this idiom too obscure to use in production code? Summary: Very, very nice answers, thanks everyone. On question (3), people felt the syntax should be clear (though I'd recommend an occasional comment, especially if your code will pass on to developers who may not be familiar with it). On question (1), The generated code should run quickly. The extra .class files do cause jar file clutter, and slow program startup slightly (thanks to coobird for measuring that). Thilo pointed out that garbage collection can be affected, and the memory cost for the extra loaded classes may be a factor in some cases. Question (2) turned out to be most interesting to me. If I understand the answers, what's happening in DBI is that the anonymous inner class extends the class of the object being constructed by the new operator, and hence has a "this" value referencing the instance being constructed. Very neat. Overall, DBI strikes me as something of an intellectual curiousity. Coobird and others point out you can achieve the same effect with Arrays.asList, varargs methods, Google Collections, and the proposed Java 7 Collection literals. Newer JVM languages like Scala, JRuby, and Groovy also offer concise notations for list construction, and interoperate well with Java. Given that DBI clutters up the classpath, slows down class loading a bit, and makes the code a tad more obscure, I'd probably shy away from it. However, I plan to spring this on a friend who's just gotten his SCJP and loves good natured jousts about Java semantics! ;-) Thanks everyone!

  • Specifying a variable name in QUERY WHERE clause in JDBC

    - by Noona
    Could someone please give me a link on how to create a query in JDBC that gets a variable name in the WHERE statement, or write an example, to be more specific, my code looks something like this: private String getLastModified(String url) { String lastModified = null; ResultSet resultSet; String query = "select LastModified from CacheTable where " + " URL.equals(url)"; try { resultSet = sqlStatement.executeQuery(query); } Now I need the syntax that enables me to return a ResultSet object where URL in the cacheTable equals url from the method's argument. thanks

  • Permutation algorithm without recursion? Java

    - by Andreas Hornig
    Hi, I would like to get all combination of a number without any repetation. Like 0.1.2, 0.2.1, 1.2.0, 1.0.2, 2.0.1, 2.1.0. I tried to find an easy scheme but couldn't find so I drawed a graph/tree for it and this screams to use recursion. But I would like to do it without, if this is possible. So could anyone please help me how to do that? Thank you in advance, Andreas

  • Flex/Flash 4 datagrid displays raw xml

    - by Setori
    Problem: Flex/Flash4 client (built with FlashBuilder4) displays the xml sent from the server exactly as is - the datagrid keeps the format of the xml. I need the datagrid to parse the input and place the data in the correct rows and columns of the datagrid. flow: click on a date in the tree and it makes a server request for batch information in xml form. Using a CallResponder I then update the datagrid's dataProvider. [code] <fx:Script> <![CDATA[ import mx.controls.Alert; [Bindable]public var selectedTreeNode:XML; public function taskTreeChanged(event:Event):void { selectedTreeNode=Tree(event.target).selectedItem as XML; var searchHubId:String = selectedTreeNode.@hub; var searchDate:String = selectedTreeNode.@lbl; if((searchHubId == "") || (searchDate == "")){ return; } findShipmentBatches(searchDate,searchHubId); } protected function findShipmentBatches(searchDate:String, searchHubId:String):void{ findShipmentBatchesResult.token = actWs.findShipmentBatches(searchDate, searchHubId); } protected function updateBatchDataGridDP():void{ task_list_dg.dataProvider = findShipmentBatchesResult.lastResult; } ]]> </fx:Script> <fx:Declarations> <actws:ActWs id="actWs" fault="Alert.show(event.fault.faultString + '\n' + event.fault.faultDetail)" showBusyCursor="true"/> <s:CallResponder id="findShipmentBatchesResult" result="updateBatchDataGridDP()"/> </fx:Declarations> <mx:AdvancedDataGrid id="task_list_dg" width="100%" height="95%" paddingLeft="0" paddingTop="0" paddingBottom="0"> <mx:columns> <mx:AdvancedDataGridColumn headerText="Receiving date" dataField="rd"/> <mx:AdvancedDataGridColumn headerText="Msg type" dataField="mt"/> <mx:AdvancedDataGridColumn headerText="SSD" dataField="ssd"/> <mx:AdvancedDataGridColumn headerText="Shipping site" dataField="sss"/> <mx:AdvancedDataGridColumn headerText="File name" dataField="fn"/> <mx:AdvancedDataGridColumn headerText="Batch number" dataField="bn"/> </mx:columns> </mx:AdvancedDataGrid> //xml example from server <batches> <batch> <rd>2010-04-23 16:31:00.0</rd> <mt>SC1REVISION01</mt> <ssd>2010-02-18 00:00:00.0</ssd> <sss>100000009</sss> <fn>Revision 1-DF-Ocean-SC1SUM-Quanta-PACT-EMEA-Scheduled Ship Date 20100218.csv</fn> <bn>10041</bn> </batch> <batches> [/code] and the xml is pretty much displayed exactly as is shown in the example above in the datagrid columns... I would appreciate your assistance.

  • Do any JS implementations currently support (or have support on the roadmap for) fast, vectorized op

    - by agnoster
    I'd like to do a bit of matrix/vector arithmetic in JavaScript, and was wondering if any browsers or other JS implementations actually have support for vectorized operations, for instance for quickly summing the entries of two Arrays (or summing, or whatever). Even if that currently doesn't mean it compiles down to vectorized operations, at least some language support would be nice for when it does get implemented - I'd take the existence of functions or syntax to support it as a step in the right direction. (Understandably, "vectorization javascript" searches are pretty much all about graphics and SVG.)
