• Not getting stage.stageWidth and stageHeight on Firefox 3.5

  - by Qpixo

  Here's a problem that I've been tried to figure out but still couldn't get the right method to fix it yet. I'm having issue regarding the display when using Firefox 3.5 on MAC, I can see my menu and the display is correct. The menu just position above what it supposed to be positioned. It works fine with Safari on MACOSX. My flash size is: 1440x750 It looks like Firefox can't recognize stage.StageWidth and stage.StageHeight. It returns 0. Some suggest implementing was to pass in the actual width and height of movie via FlashVars. The movie uses these instead of stage.stageWidth and stage.stageHeight Does anyone have an example of code of how to fix that issue?? Appreciated to point me out the right way

• Styling WPF Toolkit DataGrid Column Headers

  - by ChrisFletcher

  Hi, I'm having an issue styling the WPF Datagrid, I've styled the column headers (of type ColumnHeader). But when the data in the columns does not fill the full width of the grid an additional column is added to pad out the grid. This column ignores the ColumnHeader style and looks out of place presumably because the element has a different type, I've looked through the library in object browser but I can't find this element. I've also considered fixing the sizes so this column is unnecessary but thats not a viable option. The problem is demonstrated in the following article: http://blogs.msdn.com/jaimer/archive/2009/01/20/styling-microsoft-s-wpf-datagrid.aspx The element I mean is in the top right, just to the right of green column 3 and just above the cell with the row background arrow.

• Android RelativeLayout spacing

  - by fordays

  Hi, I'm just putting the finishing touches to my Android app. Unfortunately, I dug straight into development without reading the documentation and built my layout with AbsoluteLayout and it turned out to look terrible when I loaded the app on my phone. Now I'm redoing the UI in a RelativeLayout and I want to put empty canvas space in between my ViewGroups in the y-direction. I am currently achieving this by putting random TextView sentences that are of the same color as my View's background in order to make psuedo-empty space. Is there a better way to do this, because right now when I define a specific ViewGroup to be placed below another View, it gets stuck right below the top View. As I was writing this, it dawned upon me that using padding might be the answer.... Any other suggestions?

• PyParsing: Is this correct use of setParseAction()?

  - by Rosarch

  I have strings like this: "MSE 2110, 3030, 4102" I would like to output: [("MSE", 2110), ("MSE", 3030), ("MSE", 4102)] This is my way of going about it, although I haven't quite gotten it yet: def makeCourseList(str, location, tokens): print "before: %s" % tokens for index, course_number in enumerate(tokens[1:]): tokens[index + 1] = (tokens[0][0], course_number) print "after: %s" % tokens course = Group(DEPT_CODE + COURSE_NUMBER) # .setResultsName("Course") course_data = (course + ZeroOrMore(Suppress(',') + COURSE_NUMBER)).setParseAction(makeCourseList) This outputs: >>> course.parseString("CS 2110") ([(['CS', 2110], {})], {}) >>> course_data.parseString("CS 2110, 4301, 2123, 1110") before: [['CS', 2110], 4301, 2123, 1110] after: [['CS', 2110], ('CS', 4301), ('CS', 2123), ('CS', 1110)] ([(['CS', 2110], {}), ('CS', 4301), ('CS', 2123), ('CS', 1110)], {}) Is this the right way to do it, or am I totally off? Also, the output of isn't quite correct - I want course_data to emit a list of course symbols that are in the same format as each other. Right now, the first course is different from the others. (It has a {}, whereas the others don't.)

• Django "Page not found" error page shows only one of two expected urls

  - by Frank V

  I'm working with Django, admittedly for the first time doing anything real. The URL config looks like the following: urlpatterns = patterns('my_site.core_prototype.views', (r'^newpost/$', 'newPost'), (r'^$', 'NewPostAndDisplayList'), # capture nothing... #more here... - perhaps the perma-links? ) This is in an app's url.py which is loaded from the project's url.py via: urlpatterns = patterns('', # only app for now. (r'^$', include('my_site.core_prototype.urls')), ) The problem is, when I receive a 404 attempting to utilize newpost, the error page only shows the ^$ -- it seems to ignore the newpost pattern... I'm sure the solution is probably stupid-simple but right now I'm missing it. Can someone help get me on the right track...

• Center DIV via jQuery

  - by tony noriega

  I have a footer that is fixed to the bottom of the viewport. I am using jQuery toggle to open a comment card for users to comment and submit: $('a#footer-comment').click(function() { $("#comment-card").toggle(300); return false; $('#comment-card').show({ position:); }); $('a#footer-comment-hide').click(function() { $("#comment-card").toggle(300); return false; $('#comment-card').hide(); }); naturally if i dont add any CSS selectors to #comment-card it shows up UNDER the footer, and out of sight. So i added: {position:absolute; bottom:30px; left:auto;} 30px so it shows up above the footer which is 30px high. Problem is, i can not get this to center in the viewport... if i use pixels, depending on the resolution, it is either too far left or right... how do i center this in the viewport?

• How to open a file quickly in visual studio .net

  - by binW

  In visual studio, we can open a file in a #Include statement by right clicking the filename in include statement and then clicking "Open Document". But sometimes, when I want to open a file, I don't remember where it was in the project or where has it been included. What I do is that I open any file, add a #include statement for that file, then right-click-Open Document to open the file and then remove the #include statement that I added just to open this file. Can someone plz tell me a more straight forward way of quickly opening a file without searching for it? I am using Visual Studio 2008

• Creating PHP strings using other variables...works manually, can't figure out how automatically

  - by Matt

  Hello, I'm trying to get a variable to be formed automatically using data pulled from a mysql database. I know the data is being pulled from the database in some form resembling its original form, but that data does not act the same as data that is manually typed and assigned to a string. For example, if a cell in a mysql table says... I said "goodbye" before I left. She also said "goodbye." ...and I manually copy/paste it and add the necessary escapes... $string1 = " I said \"goodbye\" before I left. She also said \"goodbye.\" "; ...that does not equal... $string1 = $mysqlResultArray['specificCellWithQuoteShownAbove'] Interestingly, if I echo both versions of $string1 and view the output, they appear to be exactly the same. But they do not function the same when put through various functions I've created. The functions only work if I do the manual copy/paste method--which is not what I want, obviously. I'm not sure if it has to do with the line breaks or the escapes--or some combination of the two. But while both strings are superficially the same, they are apparently functionally different and I don't know why. So how can I create $string1 without manually copy/pasting the contents from the mysql entry and instead querying for the data and assigning it to $string1 in such a way that it's exactly functionally equivalent as the manual copy/pasted string?

• how to achieve this single line css format....

  - by metal-gear-solid

  I tried many formats but this is best to find classes and IDs easily without using "Find". but it is good if width of editor is wide. I use this tool to format my css in single line http://www.newmediacampaigns.com/files/posts/css-formatting/clean.php #wrapper {width:800px; margin:0 auto;} #header {height:100px; position:relative;} #feature .post {width:490px; float:left;} #feature .link {width:195px; display:inline; margin:0 10px 0 0;float:right;border-bottom:1px solid red} #footer {clear:both; font-size:93%; float:none;} I need like this. see selector #feature .link i need if any selector has more than 3 properties then it should go at next line like in this example.because i work in cms where width of textbox where i write cssis not much wide. Is there any tool/software can format CSS like this. or after getting single line format can we this formatting for big lines. in automated way #wrapper {width:800px; margin:0 auto;} #header {height:100px; position:relative;} #feature .post {width:490px; float:left;} #feature .link {width:195px; display:inline; margin:0 10px 0 0; float:right;bottom:1px solid red} #footer {clear:both; font-size:93%; float:none;}

• UINavigationController as child view of UIViewController

  - by Gregg

  I have an application that isn't nav based. So there is no UINavigationController in the App Delegate. However, I need to switch to a UINavigationController for a piece of the application. Steps I currently took... Create a new Class that extends UIViewController Added a UINavigationController via IB Told IB that the new UIViewController's view is the view for the UINavigationController The problem now is that the File's Owner needs it's view set. But via IB there is no way to specify this. So obviously, I'm not going about this the right way. Any tips in the right direction are much appreciated.

• Desimal data Type Display scale part as zero

  - by Wael Dalloul

  I have Decimal field in SQLserver 2005 table, Price decimal(18, 4) if I write 12 it will be converted to 12.0000, if I write 12.33 it will be converted into 12.3300. Always it's putting zero to the right of the decimal point in the count of Scale Part(4). I was using these in SQL Server 2000, it was not behaving like this, in SQL Server 2000 if I put 12.5 it will be stored as 12.5 not as 12.5000 what SQLServer2005 do. My Question is how to stop SQL Server 2005 from putting zeros to the right of the decimal point?

• Overriding unique indexed values

  - by Yeti

  This is what I'm doing right now (name is UNIQUE): SELECT * FROM fruits WHERE name='apple'; Check if the query returned any result. If yes, don't do anything. If no, a new value has to be inserted: INSERT INTO fruits (name) VALUES ('apple'); Instead of the above is it ok to insert the value into the table without checking if it already exists? If the name already exists in the table, an error will be thrown and if it doesn't, a new record will be inserted. Right now I am having to insert 500 records in a for loop, which results in 1000 queries. Will it be ok to skip the "already-exists" check?

• Solaris x86: Non working keys on keyboard (<, >, #, |)

  - by Thomas

  Hello everyone, I have a new installation of Solaris 10 10/09 on x86 hardware. The attached keyboard has a normal German layout. The system is configured accordingly by 'kbd -s'. The generic keys (letter, number, umlaut) work fine. Unfortunately some keys like <, , | or # do not. They produce no output on the text console at all. I tried PS/2 and USB keyboards. I cannot test it under X11 as it is currently not working. Thanks.

• Can I use my Belkin router as a repeater?

  - by Kyle R

  I've got a brand new, unopened Belkin N600 DB router (yay 50% off sale), and I can't seem to figure out if I can use it as a repeater. As far as I can tell, it doesn't support DD-WRT or Tomato, but I'm wondering if there may be some way to rig it up to repeat Wifi. Also, I really need to know before I open it, because, being a bit tight on money at the moment, I'll probably sell it if I can't use it as a repeater. Finally, two caveats: I can't use the other wireless router for anything other than broadcasting straight from the modem (parents are paranoid about anything technological). I can't run ethernet to the second router due to the layout of the house. Thanks so much for the help everyone--if I'm being vague, tell me! EDIT: Also, the manual here is pretty useless on this topic as far as I can tell.

• How to get the size of a binary tree ?

  - by Andrei Ciobanu

  I have a very simple binary tree structure, something like: struct nmbintree_s { unsigned int size; int (*cmp)(const void *e1, const void *e2); void (*destructor)(void *data); nmbintree_node *root; }; struct nmbintree_node_s { void *data; struct nmbintree_node_s *right; struct nmbintree_node_s *left; }; Sometimes i need to extract a 'tree' from another and i need to get the size to the 'extracted tree' in order to update the size of the initial 'tree' . I was thinking on two approaches: 1) Using a recursive function, something like: unsigned int nmbintree_size(struct nmbintree_node* node) { if (node==NULL) { return(0); } return( nmbintree_size(node->left) + nmbintree_size(node->right) + 1 ); } 2) A preorder / inorder / postorder traversal done in an iterative way (using stack / queue) + counting the nodes. What approach do you think is more 'memory failure proof' / performant ? Any other suggestions / tips ? NOTE: I am probably going to use this implementation in the future for small projects of mine. So I don't want to unexpectedly fail :).

• Making a Javascript game, Having a little problem with scrolling.

  I have a #wrapper div and a #grid div nested inside. currently I can scroll around with this function below. getCursorPos : function(){ // set the empty cursor object var cursor = {}; //get the offset from the left of the grid container var grid //offset loop $(function getCursorPos(){ grid = $('#grid').offset(); setTimeout(getCursorPos, game.loopSpeed); }); //continuosly get the position var that = this; $(document).mousemove(function(e){ //if game mode is menu exit if(game.mode === 'menu'){ return; } // NOTE: this looks a litle over done but don't remove anything // its like this because javascript uses floating points // and so in order to line up to the nearest hunderedth I // had to make the cursor and div position intergers by // muliplying by ten. one the two are added I reduced them // and rounded them. that.x = Math.round(((e.pageX * 10) - (grid.left * 10)) / 10); that.y = Math.round(((e.pageY * 10) - (grid.top * 10)) / 10); }); }, the problem is that the mouse coordinates only update when the mouse moves. is there any way to get the coordinates with out moving the mouse?

• python crc32 woes

  - by lazyr

  I'm writing a python program to extract data from the middle of a 6 GB bz2 file. A bzip2 file is made up of independently decryptable blocks of data, so I only need to find a block (they are delimited by magic bits), then create a temporary one-block bzip2 file from it in memory, and finally pass that to the bz2.decompress function. Easy, no? The bzip2 format has a crc32 checksum for the file at the end. No problem, binascii.crc32 to the rescue. But wait. The data to be checksummed does not necessarily end on a byte boundary, and the crc32 function operates on a whole number of bytes. My plan: use the binascii.crc32 function on all but the last byte, and then a function of my own to update the computed crc with the last 1-7 bits. But hours of coding and testing has left me bewildered, and my puzzlement can be boiled down to this question: how come crc32("\x00") is not 0x00000000? Shouldn't it be, according to the wikipedia article? You start with 0b00000000 and pad with 32 0's, then do polynomial division with 0x04C11DB7 until there are no ones left in the first 8 bits, which is immediately. Your last 32 bits is the checksum, and how can that not be all zeroes? I've searched google for answers and looked at the code of several crc32 implementations without finding any clue to why this is so.

• In-order tree traversal

  - by Chris S

  I have the following text from an academic course I took a while ago about in-order traversal (they also call it pancaking) of a binary tree (not BST): In-order tree traversal Draw a line around the outside of the tree. Start to the left of the root, and go around the outside of the tree, to end up to the right of the root. Stay as close to the tree as possible, but do not cross the tree. (Think of the tree — its branches and nodes — as a solid barrier.) The order of the nodes is the order in which this line passes underneath them. If you are unsure as to when you go “underneath” a node, remember that a node “to the left” always comes first. Here's the example used (slightly different tree from below) However when I do a search on google, I get a conflicting definition. For example the wikipedia example: Inorder traversal sequence: A, B, C, D, E, F, G, H, I (leftchild,rootnode,right node) But according to (my understanding of) definition #1, this should be A, B, D, C, E, F, G, I, H Can anyone clarify which definition is correct? They might be both describing different traversal methods, but happen to be using the same name. I'm having trouble believing the peer-reviewed academic text is wrong, but can't be certain.

• JQuery click event, not working

  - by Roland

  I have the following scenario. I have a index.php page with the following JQuery code included jQuery(document).ready(function(){ jQuery('#sIMG img').click(function(){ var currentSRC = jQuery(this).attr('src'); var altSRC = jQuery(this).attr('title'); var imgID = jQuery(this).attr('id'); var cat = jQuery(this).attr('name'); /*Fade, Callback, swap the alt and src, fade in */ jQuery('#main').fadeOut('fast',function(){ jQuery('#main').load("detail.php?id="+imgID+"&category="+cat); jQuery('#main').fadeIn('fast'); }); }); }); Now I have two div tags called #main and #right in the index.php page. When I click on a menu item right changes to a bunch of images, if I click on one of those images the above code should take effect and load into the main div, but it's just not working. the images are located within a div called sIMG. Any help will be appreciated
