• Simulating a mouse button click in Windows

  - by Ncarlson

  Hi everyone, I'm writing Remote Desktop clone in C++ using QT. So far I'm able to move the mouse cursor around fine. QT has a nice setPos function for that. However, I'm a bit lost as to what API/Library to use for simulating mouse button clicks. One method I'm aware of is to send the WM_(event) to a window using the window's HWND. However, I was hoping there was a more salient method for taking complete control over a mouse. Is there any other way to tell the operating system that the left mouse button has been clicked? Thanks.

• sorting content of a text file in python

  - by rabidmachine9

  I have this small script that sorts the content of a text file # The built-in function `open` opens a file and returns a file object. # Read mode opens a file for reading only. try: f = open("tracks.txt", "r") try: # Read the entire contents of a file at once. # string = f.read() # OR read one line at a time. #line = f.readline() # OR read all the lines into a list. lines = f.readlines() lines.sort() f = open('tracks.txt', 'w') f.writelines(lines) # Write a sequence of strings to a file finally: f.close() except IOError: pass the only problem is that the text is displayed at the bottom of the text file everytime it's sortened... I assume it also sorts the blank lines...anybody knows why? thanks in advance

• Cursors vs Procedures in SQL

  - by CogitoErgoSum

  So, I just learned about CURSORS but still don't exactly grasp them. What is the difference between a cursor and procedure or even a function? So far from the various examples (DECLARE CURSOR ... SELECT ... FROM ...) It seems at most its a variable to hold a query. Is the data real time, or a snapshot of when the cursor was declared? i.e. I have a table with one row and one col with a value of 2. I do DECLARE CURSOR ... SELECT * FROM table1 I then insert a new row with a value of 3. When I run the cursor, would I Just get the one row from before the cursor was declared, or both rows? Thanks

• How to override built-in getattr in Python?

  - by Stephen Gross

  I know how to override an object's getattr() to handle calls to undefined object functions. However, I would like to achieve the same behavior for the builtin getattr() function. For instance, consider code like this: call_some_undefined_function() Normally, that simply produces an error: Traceback (most recent call last): File "<stdin>", line 1, in <module> NameError: name 'call_some_undefined_function' is not defined I want to override getattr() so that I can intercept the call to "call_some_undefined_function()" and figure out what to do. Is this possible? Thanks, --Steve

• Error appearing in application after updating cakePHP library files from 1.3.0 to 1.3.1

  - by Gaurav Sharma

  Hi everyone, I have just updated my cakephp library to latest version 1.3.1. Before this I was running v1.3.0 with no errors. After running the application I am given this error message. unserialize() [function.unserialize]: Error at offset 0 of 2574 bytes [CORE\cake\libs\cache\file.php, line 176] I updated the libraries simply by replacing the existing cake files with the new ones downloaded from the net. Is it the correct way of updating applications. I did'nt made any customizations to the core library of cakePHP. What is the problem ? Please help. Thanks

• Loop throught form inputs

  - by Victor

  I have a form with lots of inputs. I want to get each id and value and then put them in $.load method. I tried this: $("#form input").each(function() { var name = $(this).attr("id"); var value = $(this).attr("value"); $.extend(params, { name, value }); }); and then use $.load("script.php", params); But obviously it doesn't work. In params I have only one element "name". And I'm not sure I should use extend method too.

• jQuery Mobile ScrollView "initialization"

  - by Fabio B.

  I'm using the scrollview experimental feature of jQuery Mobile: <div class="carousel" data-scroll="xp"> ... my position:absolute very large div ... </div> as described here: http://jquerymobile.com/test/experiments/scrollview/ Now I need to change the ".carousel" content dynamically: I make an ajax call in order to retrieve my new scrollview content. The content loads and shows in my div correctly, but it's not scrollable anymore! How can I rebind my "carousel" to its scrolling original behavior? Does a ".scrollview()" function actually exist? Thank you

• How can one put together multiple arrays into one string?

  - by Noor

  I'm having a hard time describing what I'm looking for. If we pretend that we're pulling an array (I've used the .split to get user input data) where each line represents a link. How can I then add an anchor tagg to that link that I'm pulling? I need to be able to put < a href=" + thearray + "anything< /a. The reason for this is that I'm dynamically creating a list. I think that if I create two variables, one with this part < a href=" one with the closing and then call some sort of function that puts those two and the pulled array in between them until the list is complete. Does this make any sense?

• How do I get bison/flex to restart scanning after something like token substitution?

  - by chucknelson

  Is there a way to force bison and/or flex to restart scanning after I replace some token with something else? My particular example would be with replacement for a specific word/string. If I want a word of hello to be replaced by echo hello, how can I get flex or bison to replace hello and then start parsing again (to pick up 2 words instead of just one). So it would be like: Get token WORD (which is a string type) If hello, replace token value with echo hello Restart parsing entire input (which is now echo hello) Get token WORD (echo) Get token WORD (hello) I've seen very tempting functions like yyrestart(), but I don't really understand what that function in particular really accomplishes. Any help is greatly appreciated, thanks!

• How can I catch a "catchable fatal error" on PHP type hinting?

  - by Ho

  Hello, I am trying to implement Type Hinting of PHP5 on one of my class, class ClassA { public function method_a (ClassB $b) {} } class ClassB {} class ClassWrong{} Correct usage: $a = new ClassA; $a->method_a(new ClassB); producing error: $a = new ClassA; $a->method_a(new ClassWrong); Catchable fatal error: Argument 1 passed to ClassA::method_a() must be an instance of ClassB, instance of ClassWrong given... May I know if it is possible to catch that error(since it says "catchable")? and if yes, how? Thank you.

• Scroll to a text position in Javascript

  - by Andy

  I have a real-time HTML editor, with a textarea on the left for code entry, and a 'preview' DIV on the right to contain the preview of the code entered. At the moment, when editing the code in the left pane, the preview just sits where it is, so often the part of the code you're editing is not in the visible area of the preview (especially when images are involved). My question is how do I make the preview scroll to show the part of the code that's currently being edited? Here is the page I have so far: http://www.caerphoto.com/rtedit.html You'll notice in the source I have a (currently unused) matchPreview() function that tries to match the scroll position of the preview based on the scroll position of the textarea, but obviously if images or large text are involved the two panes no longer match.

• Javascript in chrome plugin has syntax error

  - by Cyclone

  chrome.tabs.executeScript(null, {code:"$.each(selectValues, function(key='" + timestamp + "', value='Custom') { $('#expire'). append($(\"<option></option>\"). attr(\"value\",key). text(value)); });"}); It says that the first line has a syntax error, and the WebKit inspector shows odd highlighting patterns. What's wrong with that? A friend thinks I need to escape some characters somewhere. Thanks for the help!

• Beginner having a problem with classes

  - by David

  I'm working through O'Reilly's "Learning Python" and having a problem with classes. I think I understand the concept, but in practice have stumbled upon this problem. Fron page 88-89: >>> class Worker: def __innit__(self, name, pay): self.name=name self.pay=pay def lastName(self): return self.name.split()[-1] def giveRaise(self, percent): self.pay*=(1.0+percent) Then the book says "Calling the class like a function generates instances of a new type ...etc" and gives this example. bob = Worker('Bob Smith', 50000) This gives me this error: TypeError: this constructor takes no arguments. And then I start muttering profanities. So what am I doing wrong here? Thanks for the help.

• taking intersection of N-many lists in python

  - by user248237

  what's the easiest way to take the intersection of N-many lists in python? if I have two lists a and b, I know I can do: a = set(a) b = set(b) intersect = a.intersection(b) but I want to do something like a & b & c & d & ... for an arbitrary set of lists (ideally without converting to a set first, but if that's the easiest / most efficient way, I can deal with that.) I.e. I want to write a function intersect(*args) that will do it for arbitrarily many sets efficiently. What's the easiest way to do that? EDIT: My own solution is reduce(set.intersection, [a,b,c]) -- is that good? thanks.

• What interprocess locking calls should I monitor?

  - by Matt Joiner

  I'm monitoring a process with strace/ltrace in the hope to find and intercept a call that checks, and potentially activates some kind of globally shared lock. While I've dealt with and read about several forms of interprocess locking on Linux before, I'm drawing a blank on what to calls to look for. Currently my only suspect is futex() which comes up very early on in the process' execution. Update0 There is some confusion about what I'm after. I'm monitoring an existing process for calls to persistent interprocess memory or equivalent. I'd like to know what system and library calls to look for. I have no intention call these myself, so naturally futex() will come up, I'm sure many libraries will implement their locking calls in terms of this, etc. Update1 I'd like a list of function names or a link to documentation, that I should monitor at the ltrace and strace levels (and specifying which). Any other good advice about how to track and locate the global lock in mind would be great.

• Attaching javascript events to form widgets

  - by user334017

  I have a form with a drop down menu and I want to do a javascript action whenever the user changes the selection. I imagine it is possible find the input later, using javascript, and attach an event to to it; but it seems like it would be easier if there was some sort of attribute or option that could be defined in form-configure(): e.g. $this->widgetSchema['menu'] = new sfWidgetFormChoice(array( ... 'onclick' => javascript function )); obviously this doesn't work, and it probably wouldn't be an onclick method either, but my question is how do you attach a javascript event to a input/widget?

• Generic unboxing of boxed value types

  - by slurmomatic

  I have a generic function that is constrained to struct. My inputs are boxed ("objects"). Is it possible to unbox the value at runtime to avoid having to check for each possible type and do the casts manually? See the above example: public struct MyStruct { public int Value; } public void Foo<T>(T test) where T : struct { // do stuff } public void TestFunc() { object o = new MyStruct() { Value = 100 }; // o is always a value type Foo(o); } In the example, I know that o must be a struct (however, it does not need to be MyStruct ...). Is there a way to call Foo without tons of boilerplate code to check for every possible struct type? Thank you.

• IntPtr arithmetics

  - by Luca

  I tried to allocate an array of structs in this way: struct T { int a; int b; } data = Marshal.AllocHGlobal(count*Marshal.SizeOf(typeof(T)); ... I'd like to access to allocated data "binding" a struct to each element in array allocated with AllocHGlobal... something like this T v; v = (T)Marshal.PtrToStructure(data+1, typeof(T)); but i don't find any convenient way... why IntPtr lack of arithmetics? How can I workaround this is a "safe" way? Someone could confirm that PtrToStructure function copy data into the struct variable? In other words, modifing the struct reflect modifications in the structure array data, or not? Definitely, I want to operate on data pointed by an IntPtr using struct, without copying data each time, avoiding unsafe code. Thank all!

• PHP won't parse MySQL statements

  - by Hussain

  I just installed Apache 2.2.15/PHP 5.3.2/MySQL 5.1.44 on Windows Vista. Apache is working fine, PHP is functional, and MySQL works on the CLI. However, when I try to access MySQL via PHP, I get an error (Fatal error: Call to undefined function mysql_connect()). extension=php_mysql.dll and extension=php_mbstring.dll are uncommented in the php.ini file, and PHP is in the system path. There is no libmysql.dll in either the top level PHP directory or the ext directory. There's a libmySQL.dll file in the MySQL bin directory (which is also in the system path); I tried renaming it, but that doesn't do anything Also, in case anyone wants to know, I originally installed PHP using the MSI installer, but it was missing some DLLs, so I installed from the zip file. I think I've exhausted all my options. Any help on this problem would be very appreciated. Thanks in advance.

• Simple Moq ? - Problem with .Verify

  - by user127954

  Hi, just a simple question here. I've used Moq for awhile but, as of yet, have only used it for stubbing and not for mocking. I am trying to introduce our developers to unit testing. I set up a simple example to explain the concepts but i can't seem to get it working. Probably something simple so i thought i would just ask you all to see what i'm doing wrong: <Test()> _ Public Sub Divide_DivideByZero_LogsError() Dim mock = New Mock(Of ILogger) With mock Dim calc = New MyCalculator(New CalculatorData, .Object) calc.Divide(55, 0) mock.Object.WriteError("test", "Test") .Verify(Function(x) CType(x,ILogger).WriteError(it.IsAny(of String),It.IsAny(Of String)))) End With End Sub I'm using Moq version 3.2.416.3. I get an error on the .verify telling me that i'm calling it with incorrect arguments. I'm just trying to verify that .WriteError was called. any help would be appreciated.

• Wolfram Workbench and Mathematica Help System

  - by belisarius

  I find the Wolfram Workbench a nice environment for Mathematica development. However, as I program in Mathematica, I need to navigate the Help System very often. The Workbench provides a tooltip tool that shows a very basic help for the Mma functions (just the usage messages), and is not enough for my usual needs. So: Is there a way to bring up and navigate the whole Mma Help System from inside the Workbench? Alternative solutions are also welcome. Re-entering the function name in a notebook and pressing F1 is not :)

  Hi, I need to convert a Word document into HTML file(s) in Java. The function will take input an word document and the output will be html file(s) based on the number of pages the word document has i.e. if the word document has 3 pages then there will be 3 html files generated having the required page break. I searched for open source/non-commercial APIs which can convert doc to html but for no result. Anybody who have done this type of job before please help. Thanks

• FileReference and HttpService Browse Image Modify it then Upload it

  - by user177787

  Hello, I am trying to do an image uploader, user can: - browse local file with button.browse - select one and save it as a FileReference. - then we do FileReference.load() then bind the data to our image control. - after we make a rotation on it and change the data of image. - and to finish we upload it to a server. To change the data of image i get the matrix of the displayed image and transform it then i re-use the new matrix and bind it to my old image: private function TurnImage():void { //Turn it var m:Matrix = _img.transform.matrix; rotateImage(m); _img.transform.matrix = m; } Now the mater is that i really don't know how to send the data as a file to my server cause its not stored in the FileReference and data inside FileReference is readOnly so we can't change it or create a new, so i can't use .upload();. Then i tried HttpService.send but i can't figure out how you send a file and not a mxml.
