  • Integer variables at WIX

    - by Hila
    I would like to install a feature according to the brand. So in my brand.wxi I defined: <?define brand.FeatureLevel = 1 ?> And in my wxs I wrote: <Feature Id="FF" Title="FF" Level="$(var.brand.FeatureLevel)"> <ComponentRef Id="..." /> <ComponentRef Id="..." /> </Feature> This definition works fine (wheather I've placed 0 or 1 as FeatureLevel). My only problem is a warning I get at compilation time: The 'Level' attribute is invalid - The value '$(var.brand.FeatureLevel)' is invalid according to its datatype 'http://www.w3.org/2001/XMLSchema:integer' - The string '$(var.brand.FeatureLevel)' is not a valid Integer value. Is there a way to fix this warning? Can I define integer variable? I couldn't find a way...

  • How to make hyperlink change text in overflow:hidden div without jumping to the div

    - by paracaudex
    I have a div element with fixed height and width and overflow:hidden, and I have a menu that causes this div to scroll to anchors in the text within the div. However, when you click on an item on this menu, it doesn't just scroll the div, it also scrolls the page to the div. How do I prevent this second from happening. That is, I just want the div to scroll without the page itself scrolling. So I have <div id="boxcontent"> <p id="id1">Some content</p> <p id="id2">Some content</p> <p id="id3">Some content</p> </div> boxcontent { width:600px; height:180px; overflow:hidden; margin-left:auto; margin-right:auto; } And then a ul with anchor links to id1, id2, etc. Does this make sense?

  • function's return address is different from its supposed value, buffer overflow,

    - by ultrajohn
    Good day everyone! I’m trying to understand how buffer overflow works. I’m doing this for my project in a computer security course I’m taking. Right now, I’m in the process of determining the address of the function’s return address which I’m supposed to change to perform a buffer overflow attack. I’ve written a simple program based from an example I’ve read in the internet. What this program does is it creates an integer pointer that will be made to point to the address of the function return address in the stack. To do this, (granted I understand how a function/program variables get organized in the stack), I add 8 to the buffer variable’ address and set it as the value of ret. I’m not doing anything here that would change the address contained in the location of func’s return address. here's the program: Output of the program when gets excecuted: As you can see, I’m printing the address of the variables buffer and ret. I’ve added an additional statement printing the value of the ret variable (supposed location of func return address, so this should print the address of the next instruction which will get executed after func returns from execution). Here is the dump which shows the supposed address of the instruction to be executed after func returns. (Underlined in green) As you can see, that value is way different from the value printed contained in the variable ret. My question is, why are they different? (of course in the assumption that what I’ve done are all right). Else, what have I done wrong? Is my understanding of the program’s runtime stack wrong? Please, help me understand this. My project is due nextweek and I’ve barely touched it yet. I’m sorry if I’m being demanding, I badly need your help.

  • In Firefox 2, usage of overflow:hidden makes other divs overlap current div

    - by Shankar
    Hi, When I use overflow:hidden for div which is positioned absolute (for menu), other div overlaps. Here is the code. It works fine in FF3. Any help appreciated. Please note that html should be as it is. Also if you can provide solution, just by changing styles of menu div (the div which contains menu text) it is more helpful for me. Thanks in advance Here is the code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html> <head> <title>Title of the document</title> </head> <body> <div style="position:relative"> <div> <div style="height:20px;overflow:hidden"> <div style="position:absolute;width:200px;height:100px;top:0px;background-color:black;z-index:1">menu</div> </div> </div> <div style="position:relative;height:200px;background-color:gray;"></div> </div> </body> </html>

  • CSS: Horizontal scrolling with overflow-x

    - by ams
    Hello fellow programmers, I was wondering if there still isn't a good way to get a div to stretch and scroll horizontally, according to the images inside. -After all, it is 2011 now! The mega-width does the trick, but leaves an empty mega-space if not filled with images. If filled too much, images don't display. Same for the jQuery. The situation below is the best I can do after hours of Googling, but it isn't reliable enough. Thanks for your time. Ams * { margin:0; padding:0; } #one { width:200px; height:250px; overflow-x:auto; overflow-y:hidden; } #two { width:10000em; } #two img { float:left; } $(document).ready(function(){ var total=0; $(".calc").each(function(){ total += $(this).outerWidth(true); }); $("#two").css('width',total); alert(total); }); <div id="one"> <div id="two"> <img src="images/testimage3.jpg" width="480" height="192" class="calc"> <img src="images/testimage3.jpg" width="480" height="192" class="calc"> <img src="images/testimage3.jpg" width="480" height="192" class="calc"> <img src="images/testimage3.jpg" width="480" height="192" class="calc"> </div> </div>

  • jQuery scrolling UL with hidden overflow

    - by papermate
    I have a UL with LI's set to display horizontally. The UL has a fixed width and it's set to hide the overflow. This is so I can display my images, which are to be used in a gallery, neatly. It works and looks nice. I want to, however, use jQuery to scroll the contents of the UL rather than set the overflow property to auto and be presented with those ugly scroll bars. I recycled some code I used to do the same thing a few weeks back but, back then, I was doing it in DIV's. Much easier, apparently. $('.gallery_container span').hover( function() { if ($(this).attr('class') == 'up') direction = '-='; else direction = '+='; var divOffset = $('ul.gallery').offset().top; $('ul.gallery').animate({scrollTop: direction + divOffset}, 5000); }, function() { $('ul.gallery').stop(); }); I saw a site that says the scrollTop property can be applied to UL's. So I'm not sure what exactly is causing this not to work. Any ideas? EDIT: Found what was causing it to not work at all but not it scrolls vertically - Kind of expected that. Is there any way to scroll it horizontally?

  • Fastest way to calculate a 128-bit integer modulo a 64-bit integer

    - by Paul Baker
    I have a 128-bit unsigned integer A and a 64-bit unsigned integer B. What's the fastest way to calculate A % B - that is the (64-bit) remainder from dividing A by B? I'm looking to do this in either C or assembly language, but I need to target the 32-bit x86 platform. This unfortunately means that I cannot take advantage of compiler support for 128-bit integers, nor of the x64 architecture's ability to perform the required operation in a single instruction.

  • IE6 + IE7 CSS problem with overflow hidden

    - by googletorp
    So I have created a slider for a homepage, that slides some images with a title and teaser text using jQuery. Everything works fine, and I went to check IE and found that IE 6 and 7 kills my slider css completely. I can't figure out why, but for some reason I can't hide the non active slides with overflow: hidden; I've tried tweaking the css back and forth, but haven't been able to figure out what's causing the problem. I've recreated the problem in a more isolated html page. <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="da" lang="da" dir="ltr"> <head> <style> body { width: 900px; } .column-1 { width: 500px; float: left; } .column-2 { width: 200px; float: left; } .column-3 { width: 200px; float: left; } h4 { font-size: 16px; margin: 0 0 5px; } p { margin: 5px 0; } ul { margin: 0; padding: 0; width: 2000px; left: -499px; overflow: hidden; position: relative; } li { list-style: none; display: block; float: left; } .item-list { overflow: hidden; width: 499px; } img { display: block; } .infobox { background: black; padding: 10px 13px; margin-top: -74px; height: 54px; width: 473px; color: white; position: absolute; } .first { display: block; } </style> </head> <body> <div class="column-1"> <div class="item-list clearfix"> <ul> <li class="first"> <div class="node-slide"> <img src="http://www.hanselman.com/blog/content/binary/lolcats-funny-pictures-leroy-jenkins.jpg" /> <div class="infobox"> <h4>Title 1</h4> <p>Teaser 1</p> </div> </div> </li> <li> <div class="slide"> <img src="http://www.hanselman.com/blog/content/binary/lolcats-funny-pictures-leroy-jenkins.jpg" /> <div class="infobox"> <h4>Title 2</h4> <p>Teaser 2</p> </div> </div> </li> <li class="last"> <div class="slide"> <img src="http://www.hanselman.com/blog/content/binary/lolcats-funny-pictures-leroy-jenkins.jpg" /> <div class="infobox"> <h4>Title 3</h4> <p>Teaser 3</p> </div> </div> </li> </ul> </div> </div> <div class="column-2"> ... </div> <div class="column-3"> ... </div> </body> </html> Any ideas as to why IE wont hide images outside div with class item-list?

  • Getting overflow-y:scroll to work with fixed positioning html & css

    - by Vagabond_King
    I have a Jquery tools scrollable thats set to be fixed to the bottom of the browser window. Ideally i would just like to get a overflow-y:scroll; working for the page as a whole when the browser is < 700px. (so no content gets hidden, as its all fixed place).

  • Using logarithms to normalize a vector to avoid overflow

    - by muscicapa
    http://stackoverflow.com/questions/2293762/problem-with-arithmetic-using-logarithms-to-avoid-numerical-underflow-take-2 Having seen the above and having seen softmax normalization I was trying to normalize a vector while avoiding overflow - that is (x1 x2 x3 x4 ... xn) the normalized form for me has the sum of squares as 1.0 So what I thought of doing is s=(2*log(x1)+2*log(x2)+...+2*log(xn))/2 so the two factor can be taken off and finally the normalized vector is exp(log(x1)-s), , ..., exp(log(xn)-s) but I am evidently doing something wrong here, what?

  • Div overflow not hidden properly

    - by bbeckford
    Hi guys, I'm working on this site - http://dev.chriscurddesign.co.uk/mayday It works in everything other than IE7 and IE8 in compatibility mode (don't care about IE6), where the vacancies lists on the right aren't hidden correctly by their parent overflow property. I have been pulling my hair out trying to get to the bottom of this, its driving me up the wall, anyone got any ideas whatsoever? Below is an image of the issue, chrome on the left, IE8 compat mode on the right. Cheers, -Ben

  • Python, a smarter way of string to integer conversion

    - by Hellnar
    Hello I have written this code to convert string in such format "0(532) 222 22 22" to integer such as 05322222222 . class Phone(): def __init__(self,input): self.phone = input def __str__(self): return self.phone #convert to integer. def to_int(self): return int((self.phone).replace(" ","").replace("(","").replace(")","")) test = Phone("0(532) 222 22 22") print test.to_int() It feels very clumsy to use 3 replace methods to solve this. I am curious if there is a better solution?

  • Integer overflow exploitable?

    - by wuntee
    Does anyone have a detailed explanation on how integers can be exploited? I have been reading a lot about the concept, and I understand what an it is, and I understand buffer overflows, but I dont understand how one could modify memory reliably, or in a way to modify application flow, by making an integer larger than its defined memory....

  • Correctly assigning value to a Core Data attribute with an integer data-type

    - by Gordon Fontenot
    I'm missing something here, and feeling like an idiot about it. I'm using a UIPickerView in my app, and I need to assign the row number to a 32-bit integer attribute for a Core Data object. To do this, I am using this method: -(void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component { object.integerValue = row; } This is giving me a warning: warning: passing argument 1 of 'setIntegerValue:' makes pointer from integer without a cast What am I mixing up here? --Edit 1-- Ok, so I can get rid of the warning by changing the method to do the following: NSNumber *number = [NSNumber numberWithInteger:row]; object.integerValue = rating; However, I still get a value of 0 for object.integerValue if I use NSLog to print it out. object.integerValue has a max value of 5, so I print out number instead, and then I'm getting a number above 62,000,000. Which doesn't seem right to me, since there are 5 rows. If I NSLog the row variable, I get a number between 0 and 5. So why do I end up with a completely different number after casting the number to NSNumber? --Edit 2-- Ok, so I'm realizing that there is some fundamental idea that I don't understand. I now understand that the 60 million + number can be cast back to the correct 0-5 number by using integerValue. So, it seems my question is how can I save an integer between 0-5 to the attribute if the NSNumber that is returned is over 60 million? Do I need to be using a different data type?
