• Call the cast operator of template base class within the derived class

  - by yoni

  I have a template class, called Cell, here the definition: template <class T> class OneCell { ..... } I have a cast operator from Cell to T, here virtual operator const T() const { ..... } Now i have derived class, called DCell, here template <class T> class DCell : public Cell<T> { ..... } I need to override the Cell's cast operator (insert a little if), but after I need to call the Cell's cast operator. In other methods it's should be something like virtual operator const T() const { if (...) { return Cell<T>::operator const T; } else throw ... } but i got a compiler error error: argument of type 'const int (Cell::)()const' does not match 'const int' What can I do? Thank you, and sorry about my poor English.

• asp.net free webcontrol to display crosstab or pivot reports with column and row grouping, subtotals

  - by dev-cu

  Hello, I want to develop some crosstab also know as pivot reports in Asp.net with x-axis and y-axis being dynamics, allowing grouping by row and column, for example: have products in y-axis and date in x-axis having in body number of sells of a given product in a given date, if date in x-axis are years, i want subtotals for each month for a product (row) and subtotals of sells of all products in date (column) I know there are products available to build reports, but i am using Mysql, so Reporting Service is not an option. It's not necessary for the client build additional reports, i think the simplest solution is having a control to display such information and not using crystal report (which is not free) or something more complex, i want to know if is there an available free control to reach my goal. Well, does anybody know a control or have a different idea, thanks in advance.

• Sort and display directory list alphabetically using opendir() in php

  - by felixthehat

  Hi there, php noob here - I've cobbled together this script to display a list of images from a folder with opendir, but I can't work out how (or where) to sort the array alphabetically <?php // opens images folder if ($handle = opendir('Images')) { while (false !== ($file = readdir($handle))) { // strips files extensions $crap = array(".jpg", ".jpeg", ".JPG", ".JPEG", ".png", ".PNG", ".gif", ".GIF", ".bmp", ".BMP", "_", "-"); $newstring = str_replace($crap, " ", $file ); //asort($file, SORT_NUMERIC); - doesnt work :( // hides folders, writes out ul of images and thumbnails from two folders if ($file != "." && $file != ".." && $file != "index.php" && $file != "Thumbnails") { echo "<li><a href=\"Images/$file\" class=\"thickbox\" rel=\"gallery\" title=\"$newstring\"><img src=\"Images/Thumbnails/$file\" alt=\"$newstring\" width=\"300\" </a></li>\n";} } closedir($handle); } ?> Any advice or pointers would be much appreciated!

• Win32 call order

  - by DD

  Hi all, I have two windows that I send scripted input to. The procedure goes as this BringWindowToTop( window1 ); i = Build input structures( window1 ); SendInput(i); BringWindowToTop( window2 ); i = Build input structures( window2 ); SendInput(i); I was having trouble with inputs not being sent and the correct time. I put delays after each call and saw that input from the first SendInput() was processed after window2 is brought to top. Same thing at the end of the loop as well. Are SendInput calls buffered? If so, how can I make sure of a serial execution of this code? Thanks

• Media Foundation: another way to call IMFActivate::ShutdownObject?

  - by KenC

  Hi, Here is a question about IMFActivate::ActivateObject and IMFActivate::ShutdownObject in Media Foundation. According to MSDN, the component that calls ActivateObject is responsible for calling ShutdownObject. But there are two examples not following this rule: http://msdn.microsoft.com/en-us/library/dd388503%28VS.85%29.aspx and http://msdn.microsoft.com/en-us/library/dd317912%28VS.85%29.aspx In these two examples, they call ActivateObject and then release IMFActivate interface without calling ShutdownObject method. This is going to lead to memory leaking, right? Or there is another way to release the resource occupied by the object? (Can I use IMFMediaSource::Shutdown to release the object instead of using IMFActivate::ShutdownObject) Thanks in advance.

• coding an array in a class library and make a call to it C#

  - by eddy

  I'm new to C#, so this may be a basic question. What I need to do is put an array such as the one below in a class library and then make a call to it. So I'd want the aproprate picture to appear via the class and this array. I know there's a much simpler way to make certain pictures appear, but this is a requirement for the project. It's an asp.NET website in C#. string[] PictureArray; PictureArray = new string[3]; PictureArray[0] = "~/pics/grl.jpg"; PictureArray[1] = "~/pics/pop.jpg"; PictureArray[2] = "~/pics/str.jpg"; PictureArray[3] = "~/pics/unk.jpg";

• Dynamically call a stored procedure from another stored procedure

  - by Greg

  I want to be able to pass in the name of a stored procedure as a string into another stored procedure and have it called with dynamic parameters. I'm getting an error though. Specifically I've tried: create procedure test @var1 varchar(255), @var2 varchar(255) as select 1 create procedure call_it @proc_name varchar(255) as declare @sp_str varchar(255) set @sp_str = @proc_name + ' ''a'',''b''' print @sp_str exec @sp_str exec call_it 'test' So procedure call_it should call procedure test with arguments 'a', and 'b'. When I run the above code I get: Msg 2812, Level 16, State 62, Procedure call_it, Line 6 Could not find stored procedure 'test 'a','b''. However, running test 'a','b' works fine.

• groovy call private method in Java super class

  - by Jeff Storey

  I have an abstract Java class MyAbstractClass with a private method. There is a concrete implementation MyConcreteClass. public class MyAbstractClass { private void somePrivateMethod(); } public class MyConcreteClass extends MyAbstractClass { // implementation details } In my groovy test class I have class MyAbstractClassTest { void myTestMethod() { MyAbstractClass mac = new MyConcreteClass() mac.somePrivateMethod() } } I get an error that there is no such method signature for somePrivateMethod. I know groovy can call private methods but I'm guessing the problem is that the private method is in the super class, not MyConcreteClass. Is there a way to invoke a private method in the super class like this (other than using something like PrivateAccessor)? thanks Jeff

• OpenFileDialog - only display filenames that have no extensions

  - by fraXis

  Hello, I have the following code in my C# program: OpenFileDialog fDialog = new OpenFileDialog(); fDialog.Title = "Open a file"; fDialog.Filter = "NCF files (*.ncf)|*.ncf|All files (*.*)|*.*|No Extensions (*.)|*."; I want to be able to have the user pick from the following: .NCF (files with .NCF extension only) *.* (all files) and files that have no extensions such as: readme (with no .txt) I know *.* will do this, but it also displays the .NCF, .TXT, and all other files in the same directory. I just want to be able to display filenames that have no extensions. Filtering with *. does not do the trick. Is there a way I can do this with C#? Thanks.

• Call click event on last clicked row in YUI datatable

  - by Javi

  Hello, I have a YUI datatable and I have a function which is invoked when I click on a row: ... YAHOO.keycoes.myDatatable = myDatatable; ... myDatatable.subscribe("rowClickEvent", oneventclickrow); var oneventclickrow = function( args ) { ... } I'd like to invoke the function subscribed to rowClickEvent on the row which is currently highlighted in the datatable (the row which was clicked for the last time). I've tried to do something like this: YAHOO.keycoes.myDatatable.getSelectedRows()[0].rowClickEvent() but getSelectedRows() doesn't return any row. How can I get the highlighted row in the datatable and then call the function associated with rowClickEvent? Thanks

• NSNumberFormatter to display custom labels for 10^n (10000 -> 10k)

  - by Michele Colombo

  I need to display numbers on a plot axis. The values could change but I want to avoid too long numbers that will ruin the readability of the graph. My thought was to group every 3 characters and substitute them with K, M and so on (or a custom character). So: 1 - 1, 999 - 999, 1.000 - 1k, 1.200 - 1.2k, 1.280 - 1.2k, 12.800 - 12.8k, 999.999 - 999.9k, 1.000.000 - 1M, ... Note that probably I'll only need to format round numbers (1, 10, 1000, 1500, 2000, 10000, 20000, 30000, 100000, ...). Is that possibile with NSNumberFormatter? I saw that it has a setFormat method but I don't know how much customizable it is. I'm using NSNumberFormatter cause the graph object I use wants it to set label format and I want to avoid changing my data to set the label.

• Call function under object from string

  - by sam

  I have a script which creates a drag-and-drop uploader on the page from a div. My DIV will look something like <div class="well uploader" data-type="image" data-callback="product.addimage" data-multi="1"></div> Then I'll have a function something like var product = new function(){ /* Some random stuff */ this.addimage = function(image){ alert('W00T! I HAZ AN IMAGE!'); } /* More random stuff */ } When the upload is complete, I need to call the function in data-callback (In this example, product.addimage). I know with global functions you can just do window[callback]() but I'm not sure the best way to do this with functions under objects. My first thought was to do something like* var obj = window; var parts = callback.split('.'); for(part in parts){ obj = obj[parts[part]]; } obj(); but that seems a bit dirty, is there a better way without using eval because eval is evil? I haven't tested this so I have no idea if it will work

• ASP.NET Call Another Element's DoPostBack Function

  - by blu

  I have an ASP.NET control that has an onclick event handler rendered inline on the element. I would like to call that function and have it raise the target control's server side event handler. <asp:CheckBox ID="Foo" runat="server" AutoPostBack="true" Text="Foo" /> <a href="#" onclick="javascript:setTimeout('__doPostBack(\'Foo\',\'\')', 0)">Test </a> I created the checkbox, looked at the rendered function on the field, and then copied that into the onclick on the anchor element. The anchor will raise a postback, but the event handler for the check box is not raised. protected override void OnLoad(EventArgs e) { // fires for checkbox // fires for anchor (the anchor does cause a postback) } void Foo_CheckedChanged(object sender, EventArgs e) { // fires for checkbox // does not fire for anchor } protected override void OnInit(EventArgs e) { this.Foo.CheckedChanged += new EventHandler(Foo_CheckedChanged); } Is it possible to do this?

• javax script how to call a function in JavaScript from Java

  - by Dan Howard

  Hi All, I'm trying to call a function in JavaScript via Java. This works fine when directly reading a script as a string but I'm using CompiledScripts. When I do this with a compiled script it gives me method not found if I also add bindings. Without bindings it works but of course the function fails because it needs the bindings. Any ideas? CompiledScript script = ... get script.... Bindings bindings = script.getEngine().createBindings(); Logger scriptLogger = LogManager.getLogger("TEST_SCRIPT"); bindings.put("log", scriptLogger); //script.eval(bindings); -- this way fails script.eval(); // -- this way works Invocable invocable = (Invocable) script.getEngine(); invocable.invokeFunction(methodName); TIA

• How to call an extended procedure from a function

• Help needed with Javascript Variable Scope / OOP and Call Back Functions

  - by gargantaun

  I think this issue goes beyond typical variable scope and closure stuff, or maybe I'm an idiot. Here goes anyway... I'm creating a bunch of objects on the fly in a jQuery plugin. The object look something like this function WedgePath(canvas){ this.targetCanvas = canvas; this.label; this.logLabel = function(){ console.log(this.label) } } the jQuery plugin looks something like this (function($) { $.fn.myPlugin = function() { return $(this).each(function() { // Create Wedge Objects for(var i = 1; i <= 30; i++){ var newWedge = new WedgePath(canvas); newWedge.label = "my_wedge_"+i; globalFunction(i, newWedge]); } }); } })(jQuery); So... the plugin creates a bunch of wedgeObjects, then calls 'globalFunction' for each one, passing in the latest WedgePath instance. Global function looks like this. function globalFunction(indicator_id, pWedge){ var targetWedge = pWedge; targetWedge.logLabel(); } What happens next is that the console logs each wedges label correctly. However, I need a bit more complexity inside globalFunction. So it actually looks like this... function globalFunction(indicator_id, pWedge){ var targetWedge = pWedge; someSql = "SELECT * FROM myTable WHERE id = ?"; dbInterface.executeSql(someSql, [indicator_id], function(transaction, result){ targetWedge.logLabel(); }) } There's a lot going on here so i'll explain. I'm using client side database storage (WebSQL i call it). 'dbInterface' an instance of a simple javascript object I created which handles the basics of interacting with a client side database [shown at the end of this question]. the executeSql method takes up to 4 arguments The SQL String an optional arguments array an optional onSuccess handler an optional onError handler (not used in this example) What I need to happen is: When the WebSQL query has completed, it takes some of that data and manipulates some attribute of a particular wedge. But, when I call 'logLabel' on an instance of WedgePath inside the onSuccess handler, I get the label of the very last instance of WedgePath that was created way back in the plugin code. Now I suspect that the problem lies in the var newWedge = new WedgePath(canvas); line. So I tried pushing each newWedge into an array, which I thought would prevent that line from replacing or overwriting the WedgePath instance at every iteration... wedgeArray = []; // Inside the plugin... for(var i = 1; i <= 30; i++){ var newWedge = new WedgePath(canvas); newWedge.label = "my_wedge_"+i; wedgeArray.push(newWedge); } for(var i = 0; i < wedgeArray.length; i++){ wedgeArray[i].logLabel() } But again, I get the last instance of WedgePath to be created. This is driving me nuts. I apologise for the length of the question but I wanted to be as clear as possible. END ============================================================== Also, here's the code for dbInterface object should it be relevant. function DatabaseInterface(db){ var DB = db; this.sql = function(sql, arr, pSuccessHandler, pErrorHandler){ successHandler = (pSuccessHandler) ? pSuccessHandler : this.defaultSuccessHandler; errorHandler = (pErrorHandler) ? pErrorHandler : this.defaultErrorHandler; DB.transaction(function(tx){ if(!arr || arr.length == 0){ tx.executeSql(sql, [], successHandler, errorHandler); }else{ tx.executeSql(sql,arr, successHandler, errorHandler) } }); } // ---------------------------------------------------------------- // A Default Error Handler // ---------------------------------------------------------------- this.defaultErrorHandler = function(transaction, error){ // error.message is a human-readable string. // error.code is a numeric error code console.log('WebSQL Error: '+error.message+' (Code '+error.code+')'); // Handle errors here var we_think_this_error_is_fatal = true; if (we_think_this_error_is_fatal) return true; return false; } // ---------------------------------------------------------------- // A Default Success Handler // This doesn't do anything except log a success message // ---------------------------------------------------------------- this.defaultSuccessHandler = function(transaction, results) { console.log("WebSQL Success. Default success handler. No action taken."); } }
