• An explanation of memory usage on Windows server 2003

  - by Rich

  Hi, We've been working on a bit of puzzle at work. We have an application service installed on two machines, both running Windows server 2003. These services do exactly the same thing. However once loaded, one of the services uses 200mb less than the other service. We're at a bit of a loss to what might be causing this discrepancy. I was wondering if there was some kind of server setting that would cause an application to use more memory (heap block size) or anything to explain this. If anyone has any ideas on what may be causing this, or how to find out what is causing this I'd be very grateful. Cheers Rich

• What types of conditions can be used for conditional compilation in C++?

  - by user1002288

  This is an exam question for C++: Which of the following statements accurately describe the condition that can be used for conditional compilation in C++? A. The condition can depend on the value of environment variables. B. The condition can depend on the value of any const variables. C. The condition can depend on the value of program variables. D. The condition can use the sizeof() operator to make decision about compiler-dependent operations based on the size of standard data type. E. The condition must evaluate to either a 0 or 1 during preprocessing. I think the answer is E. Is this correct?

• MKPinAnnotationView - hard to drag

  - by James Zaghini

  I have a MKPinAnnotationView that the user can drag around the map. It is very difficult for a user to drag the pin. I've tried increasing the frame size and also using a giant custom image. But nothing seems to actually change the hit area for the drag to be larger than default. Consequently, I have to attempt to tap/drag about ten times before anything happens. MKPinAnnotationView *annView = [[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"bluedot"] autorelease]; UIImage *image = [UIImage imageNamed:@"blue_dot.png"]; annView.image = image; annView.draggable = YES; annView.selected = YES; return annView; What am I missing here?

• How to display Youtube videos in a jQuery lightbox (Wordpress)?

  - by janoChen

  I tried lightbox-plus, fancybox, etc... But I couldn't figure how to do it. Those videos are images posts with a link containing a Youtube video: <p><a href="http://www.youtube.com/watch?v=zUN826BdvV4"> <img class="alignnone size-thumbnail wp-image-40" title="Screenshot" src="http://localhost/custom-post-type/ wp-content/uploads/2011/01/Screenshot2-150x150.png" alt="" width="150" height="150" /></a></p> Fancybox for Wordpress, for example, let me add a lightbox to images, but if the image links to a Youtube video it doesn't work. Any suggestions?

• Cast A primitive type pointer to A structure pointer - Alignment and Padding?

  - by Seçkin Savasçi

  Just 20 minutes age when I answered a question, I come up with an interesting scenario that I'm not sure of the behavior: Let me have an integer array of size n, pointed by intPtr; int* intPtr; and let me also have a struct like this: typedef struct { int val1; int val2; //and less or more integer declarations goes on like this(not any other type) }intStruct; My question is if I do a cast intStruct* structPtr = (intStruct*) intPtr; Am I sure to get every element correctly if I traverse the elements of the struct? Is there any possibility of miss-alignment(possible because of padding) in any architecture/compiler?

• Can SQL Server 2008 Express be used for offering commercial web hosting services?

  - by Tony_Henrich

  I read that SQL Server 2008 Express R2 database size limit has increased to 10G. That's good news. Can I use the Express edition of SQL Server to offer web hosting services to the public? Microsoft should be best in answering this but I can't find a clear answer on their site. I am also seeing several Windows web hosting plans include SQL Server as a total package for less than $5/month. I am wondering how they can afford to offer this.

• Button border radius and cursor

  - by noober

  CSS border radius does affect button rendering (I see it's round form), but does not affect how it interacts with the user (I still can click button outside its border). How should I fix it? I see the behavior in Chrome. button { cursor: pointer; outline: none; background-size: 100% 100%; background-color: red; /*transparent;*/ /* It's actually red and ROUND. */ background-position: center center; background-repeat: no-repeat; border: 0px; -webkit-border-top-left-radius: 73px; -webkit-border-top-right-radius: 73px; -webkit-border-bottom-left-radius: 73px; -webkit-border-bottom-right-radius: 73px; width: 146px; height: 146px; background-image: url('leftarrow.png'); } Regards,

• Does @import in CSS result in additional http requests?

  - by Mo Boho

  I have an ecommerce site that has about 8 CSS files linked from the header - resulting in 8 separate http requests to the server. I consolidated all the CSS files into 1 big one, resulting in a 67kb (!) file - to cut down the http requests to 1 for our css files. I'm finding this size a CSS file a little unmanageable in light of the fact I'm performing updates on the site constantly. My concern is my users may catch me in the middle of updating and see a NON-styled page when moving from page to page - b/c 67kb still takes a good 2-3 seconds before it is successfully placed on the remote server via FTP. My question is: does the use of @import within this large CSS file to break up the files into smaller more manageable sizes (within that CSS file) take us back to the original 8 http-requests when the pages is loaded? Or are @imports in CSS handle differently somehow?

• structure in .NET

  - by redpaladin

  My problem is very simple.. My problem is to send a structure beetween a program in C to a C# program.. I made a struct in C#: public struct NetPoint { public float lat; // 4 bytes public float lon; // 4 bytes public int alt; // 4 bytes public long time; // 8 bytes } Total size of the struct must be 20 bytes When i do a sizeof() of this struct System.Diagnostics.Debug.WriteLine("SizeOf(NetPoint)=" + System.Runtime.InteropServices.Marshal.SizeOf(new NetPoint())); The debug console show : SizeOf(NetPoint)=24 But i expected to have 20 bytes ? Why do I have a difference ? Thank you in advance

• HABTM checking for match of latest 3

  - by user333614

  Here's an interesting one for you folks... I have a HABTM (has_and_belongs_to_many) relationship between "Dogs" and "Trips". My goal is to find two result sets: 1) Dogs that have been on at least 1 of the last 3 trips and call that @dogs_current 2) Dogs that have NOT been on any of the last 3 trips and call that @dogs_old I found that I can find what the last 3 trips are by doing this in the Trip model: named_scope :last3, :order => 'date DESC', :limit => 3 But not sure how to use that list get 1 and 2. This hack works, but it seems ugly. There must be a better way! :) @dogs_current = [] @dogs_old = [] @dogs.each do |dog| if (Trip.last3 - dog.trips).size < 3 then @dogs_current << dog else @dogs_old << dog end end Any ideas? Thanks! -Cam

• C: Why does gcc allow char array initialization with string literal larger than array?

  - by Ashwin

  int main() { char a[7] = "Network"; return 0; } A string literal in C is terminated internally with a nul character. So, the above code should give a compilation error since the actual length of the string literal Network is 8 and it cannot fit in a char[7] array. However, gcc (even with -Wall) on Ubuntu compiles this code without any error or warning. Why does gcc allow this and not flag it as compilation error? gcc only gives a warning (still no error!) when the char array size is smaller than the string literal. For example, it warns on: char a[6] = "Network"; [Related] Visual C++ 2012 gives a compilation error for char a[7]: 1>d:\main.cpp(3): error C2117: 'a' : array bounds overflow 1> d:\main.cpp(3) : see declaration of 'a'

• Positioning child panels using FlowLayout

  - by extro

  I have two panels: main_panel child_panel The main_panel layout is set using: main_panel.setLayout(flowlayout) I then added child_panel to main_panel: main_panel.add(child_panel) The child_panel gets added to main_panel but its position is at the cross-section of horizontal midpoint and top vertical section of screen. I want child_panel to be at the top left corner, something I could have done by using child_panel.setlocation(a,b) method, if I have set the layout of main_panel as null. I have used FlowLayout here because I want components in the JPanel to keep adjusting with the size of JFrame. So can I add child_panel to main_panel at the exact location I want, even if I set the Layout of main_panel as not null?

• Android: Scrollable (bitmap) screen

  - by somin

  I am currently implementing a view in Android that involves using a larger than the screen size bitmap as a background and then having drawables drawn ontop of this. This is so as to simulate a "map" that can be scrolled horizontally aswell as vertically. Which is done by using a canvas and then drawing to this the full "map" bitmap, then putting the other images on top as an overlay and then drawing only the viewable bit of this to screen. Overriding the touch events to redraw the screen on a scroll/fling. I'm sure this probably has a huge ammount of overhead (by creating a canvas of the full image whilst using(drawing) only a fifth of it) and could be done in a different way as to the explained, but I was just wondering what people would do in this situation, and perhaps examples? If you need more info just let me know, Thanks, Simon

• How to arrange labels in a flowlayout manner?

  - by Tim Büthe

  How do I arrange some UILabels and/or UIButtons of a variable length? I just want to add them to a UITableViewCell and they should arrange in a left-to-right flow, much like lines of text in a paragraph. I only found possibilities to create lables with a fixed size and position using "initWithFrame:...". Same seems to be true for Interface Builder, as far as I can tell. Any solution is appreciated no matter if it's done in code or using a custom cell XIB-file.

• How can I stretch a DIV to 100%, without streching its auto-width parent element?

  - by Chris... S...

  Given a formular with several fieldsets: <form> <fieldset id="a"></fieldset> <fieldset id="b"></fieldset> </form> All fieldsets are to have the same width, whereas it should be the width of the broadest fieldset. The form element has no explicit width. How can I achieve that? I thought width: 100% would do it, but it will stretch the form element to window size.

• Android 3.2 HTTP streaming

  - by user1281053

  I'm trying to create an app to stream live TV. Currently the problem I'm facing is that after say 10 minutes of playing, the video will freeze but the audio will carry on. This is on a 1.3mbps stream. I also have lower streams, such as a 384kbps stream, that might last an hour or so, but will still do the same. I've tested this with a local video, that is high quality (file size is 2.3gb) and that has no lag and doesn't freeze at all, so it must be something to do with the way HLS is streamed to android. Does anyone have any idea on how to solve this problem? Thanks
