How to do a for loop in windows command line?

- by TheFoxx

I was wondering if this was possible? I'm not familiar with using windows command line, but I have to use it for a project I'm working on. I have a a number of files, for which I need to perform a function for each. I'm used to working with python, but obviously this is a bit different, so I was hoping for some help. Basically I need the for loop to iterate through 17 files in a folder, perform a function on each (that's using the specific software I have here for the project) and then that will output a file with a unique name (the function normally requires me to state the output file name) I would suck it up and just do it by hand for each of the 17, but basically it's creating a database of a file, and then comparing it to each of the 17. It needs to be iterated through several hundred times though. Using a for loop could save me days of work. Suggestions?

Class Members Over Exports

- by VirusEcks

When Using DLLs or Code-injecting to be Specific this is an example class only intended for explaining class test { int newint1; char newchararray[512]; void (*newfunction1)( int newarg1 ); int newfunction2( bool newarg1, char newarg2 ) { return newint1; } } mynewclass1; that covers most common elements that's included in classes now when exporting this function to another DLL or application and missed an element of those, either data member or function member, private or public what happens or changed their order ? and if each function is assigned it's value when Code-Injecting like mynewclass1.newfunction1 = (void *)(newexportedfunction); what's the happens in this case, if members of the class are pointers that are assigned after class construction and then missed one member or changed their order ?

Can I use a static var to "cache" the result? C++

- by flyout

I am using a function that returns a char*, and right now I am getting the compiler warning "returning address of local variable or temporary", so I guess I will have to use a static var for the return, my question is can I make something like if(var already set) return var else do function and return var? This is my function: char * GetUID() { TCHAR buf[20]; StringCchPrintf(buf, 20*sizeof(char), TEXT("%s"), someFunction()); return buf; } And this is what I want to do: char * GetUID() { static TCHAR buf[20]; if(strlen(buf)!=0) return buf; StringCchPrintf(buf, 20*sizeof(char), TEXT("%s"), someFunction()); return buf; } Is this a well use of static vars? And should I use ZeroMemory(&buf, 20*sizeof(char))? I removed it because if I use it above the if(strlen...) my TCHAR length is never 0, should I use it below?

Old functions return 'undefined' error once I add a jquery reference

- by Lapa

Disregard this question: I've simply confused <script src="..."></script> tag and <script> [some functions] </scipt> tags. I have this function function OnLoad() { ShowHideConfirmAnswers(); return true; } triggered by onload event: <body onload=OnLoad()> It works fine until I add src="jquery-1.4.2.js" to the script element. From this moment I get "OnLoad is not defined" error, and the same happens to every other javascript function.

Aborted core dumped C++

- by avd

I have a large C++ function which uses OpenCV library and running on Windows with cygwin g++ compiler. At the end it gives Aborted(core dumped) but the function runs completely before that. I have also tried to put the print statement in the end of the function. That also gets printed. So I think there is no logical bug in code which will generate the fault. Please explain. I am also using assert statements.But the aborted error is not due to assert statement. It does not say that assertion failed. It comes at end only without any message. Also the file is a part of a large project so I cannot post the code also.

How do you pass an enum by reference?

- by Darkenor

I have an enum with four keys I'm taking as input for an interface program and I'd like to pass the enum by value to the interface function, which has become quite long. The enum is like this: enum MYKEYS { W, S, O, L }; There's also a boolean array that I have to pass by reference, which is also a little tricky. bool key[4] = { false, false, false, false }; Does anyone know the proper syntax to pass both of these as reference in a function, similar to: function(int & anintreference);

jQuery DIV click, with anchors

- by ANaimi

To make click-able divs, I do: <div class="clickable" url="http://google.com"> blah blah </div> and then $("div.clickable").click( function() { window.location = $(this).attr("url"); }); I don't know if this is the best way, but it works perfectly with me, except for one issue: If the div contains a click-able element, such as <a href="...">, and the user clicks on the hyperlink, both the hyperlink and div's-clickable are called This is especially a problem when the anchor tag is referring to a javascript AJAX function, which executes the AJAX function AND follows the link in the 'url' attribute of the div. Anyway around this?

Sleeping a thread blocking stdin

- by Sid

Hey, I'm running a function which evaluates commands passed in using stdin and another function which runs a bunch of jobs. I need to make the latter function sleep at regular intervals but that seems to be blocking the stdin. Any advice on how to resolve this would be appreciated. The source code for the functions is def runJobs(comps, jobQueue, numRunning, limit, lock): while len(jobQueue) >= 0: print(len(jobQueue)); if len(jobQueue) > 0: comp, tasks = find_computer(comps, 0); #do something time.sleep(5); def manageStdin(): print "Global Stdin Begins Now" for line in fileinput.input(): try: print(eval(line)); except Exception, e: print e; --Thanks

jQuery: Listen to changes within a DIV and act accordingly

- by Chris

I have a function that grabs an XML document and transforms it according to an XSL document. It then places the result into a div with the id laneconfigdisplay. What I want to do is, separate to the transformation logic, setup a jQuery change event for that div so I can tell when it has changed, and run some jQuery code. I have tried the following, but it does not work! $(document).ready(function() { $('#laneconfigdisplay').change(function() { alert('woo'); }); //Do XML / XSL transformation here });  <div id="laneconfigdisplay"></div> What am I doing wrong?

jQuery - Using .one() with hover

- by Jared

Is there any way to get a hover function to only execute once? This is what I'm currently trying: $('#ask').live('hover', function() { $('#homesearch-after').hide(300); $.doTimeout( 300, function() { hideClosedSearchLink(); showHomeSearch(); }); }); But that's not working. How can I only get this hover to activate once? I've tried changing .live with .one and .bind... resulting in nothingness.

pointers in C with a #define

- by milan

The function: #define ASSOC(port) (*(volatile bit_field *) (&port)) The function call: #define SCLK ASSOC(PORTC).bit0 bit_field defined as a struct like this: typedef struct { unsigned char bit0 :1, bit1 :1, bit2 :1, bit3 :1, bit4 :1, bit5 :1, bit6 :1, bit7 :1; } bit_field; I don't know where &port is defined. Can someone please explain how the function is read and how it works please? I am not very good with pointers and this example in particular is very confusing with "*" in the front and at the end and the "&" with the port. Thank you

Does remove a DOM object (in Javascript) will cause Memory leak if it has event attached?

- by seatoskyhk

So, if in the javascript, I create a DOM object in the HTML page, and attach event listener to the DOM object, upon I remove the the DOM from HTML page, does the event listener still exist and causing memory leak? function myTest() { var obj = document.createElement('div'); obj.addEventListener('click', function() {alert('whatever'); }); var body = document.getElementById('body'); // assume there is a <div id='body'></div> already body.appendChild(obj); } // then after some user actions. I call this: function emptyPage() { var body = document.getElementById('body'); body.innerHTML = ''; //empty it. } So, the DOM object, <div> inside body is gone. But what about the eventlistener? I'm just afraid that it will cause memory leak.

Is it possible to append html code in parts via JQuery?

- by phpheini

I am trying to append li elements coming from a php file with JQuery. Problem is that the html code needs to be seperately appended to different html IDs according to the key value. Unfortunately as I understood append() can only append correct html with all elements closed. Otherwise it will automatically close the tags. The following code will NOT work as dval contains code like <div><li class="some">Some value</li> and append() will make <div><li class="some">Some value</li></div> out of it. So I was wondering whether there is another way, maybe a function other than append() to be able to append html parts? $.each(obj, function(key,val) { $.each(obj[key], function(key, dval) { if(key == "text") { $("#" + key).append(dval); } }) });

Return value in Visual Studio's Autos window

- by Dave

When I used to develop in C++, I remember that Visual Studio had an entry in its Autos window whenever returning from a function call. This entry would tell me what value was returned from that function. One might argue that if a function returns a value, then you should set a variable to that value, i.e. int i = GetRandomInt(); But as a contrived example, suppose I wanted to do this: CycleTushKicker( GetRandomInt()); Instead of stepping into CycleTushKicker to figure out how many lickings my kid gets, I'd just like to know the value as soon as I exit GetRandomInt. Is there a way to get this when using C#?

Creating a textarea with auto-resize

- by DisgruntledGoat

There was another thread about this, which I've tried. But there is one problem: the textarea doesn't shrink if you delete the content. I can't find any way to shrink it to the correct size - the clientHeight value comes back as the full size of the textarea, not its contents. The code from that page is below. I'd appreciate any help or pointers. function FitToContent(id, maxHeight) { var text = id && id.style ? id : document.getElementById(id); if ( !text ) return; var adjustedHeight = text.clientHeight; if ( !maxHeight || maxHeight > adjustedHeight ) { adjustedHeight = Math.max(text.scrollHeight, adjustedHeight); if ( maxHeight ) adjustedHeight = Math.min(maxHeight, adjustedHeight); if ( adjustedHeight > text.clientHeight ) text.style.height = adjustedHeight + "px"; } } window.onload = function() { document.getElementById("ta").onkeyup = function() { FitToContent( this, 500 ) }; }
