  - by Azzyh

  what i want to do is that when you vote Y or N (two different radio buttons) and then it inserts into the "vote" column(in database) = Y or N(what you pickd), if nothing then echo error. I know how to do this like halfway, i never worked with radiobuttons before so i need you guys. Here's a two radio button right: Yes: <input type="radio" value="Y" id="voteYes" name="vote"></input> <br> No: <input type="radio" value="N" id="voteNo" name="vote"> </input> I gave the value N and Y, not the same ID, but the same name. I think its right, but how should i do with the PHP part of what i want to do? I mean shall i call for "vote"? ($_GET["vote"]) i dont think so.. here's where im stuck

• making errorbars not clipped in matplotlib with Python

  - by user248237

  I am using matplotlib in Python to plot a line with errorbars as follows: plt.errorbar(xvalues, up_densities, yerr=ctl_sds, fmt='-^', lw=1.2, markersize=markersize, markeredgecolor=up_color, color=up_color, label="My label", clip_on=False) plt.xticks(xvalues) I set the ticks on the x-axis using "xticks". However, the error bars of the last point in xvalues (i.e. xvalues[-1]) are clipped on the right -- meaning only half an error bar appears. This is true even with the clip_on=False option. How can I fix this, so that the error bars appear in full, even though their right side is technically outside xvalues[-1]? thanks.

• Will iPhone App with future "Availability Date" show up in "New Releases" on that day?

  - by Heiko Weible

  I plan to submit my first iPhone game "The Twiggles" to the iPhone app store today. Like many people suggest, I want to set the "Availability Date" to a date way in the future and change it later. But there are two different opinions on what to do once the app is approved: A: Some people say, I have to quickly change the "Availability Date" to the date the app is approved by Apple right after I get the "app approved" mail. Otherwise it won't show up in the "New Releases" list. B: Some people say, this is not necessary (or maybe no longer necessary). I can set the "Availability Date" to some date in the future (for example, next weekend). The app will be released on that day and will show up in the "New Releases" list on that day. Who is right?

• WPF problem modify style of images in multiple Button Templates

  - by user556415

  I'm trying to create a control panel for a video camera, the panel has buttons for up, down, left and right etc. Each camera function up, down, left and right is represented by three images (see code below) for the left side, middle and right side. The control panel is circular so the corner images kind of overlap (its complicated to explain this without a visual). When I click on up for example I have to hide the initial three images (leftside, middle and right side) and display another three images for left , middle and right that indicate that the button is pressed. I am achieving this by having a grid inside a button template. The problem I have is that for the corner images for the control there are really four images that represent this. For example for the top left corner the four images would be represent 1. Top not clicked. 2. Top Clicked and 3. Left Not clicked and 4. Left Clicked. My problem is if I need to make the images contained within the Top button have precedence when the top control is clicked or the images in the left button have precedence when the left button is clicked. So it's like I want to modify the left button's image visible property when the top button is clicked and vise versa. This is really difficult to explain so I apologize if it makes little sense but I can email the source code on request if anyone is interested in my predicament. <Grid> <Canvas> <!--<StackPanel>-->

• Notepad++ Move Caret Outside Bracket

  - by marknadal

  I've searched everywhere and can't find an answer to something incredibly simple and useful for Notepad++. When using autoclose, the cursor gets stuck inside, which is good until I've finished typing the parameters. How do I get the caret to jump outside of the currently nested autoclosed element? Regardless of it being (), {}, [], "", '', ? CTRL+B does does something similar, but it goes to the inside of the left bracket first, and then to the outside of the right bracket, which is where I want to be. This only works for brackets though, not tags and qoutations Hitting CTRL+B twice is cumbersome and manually hitting "right arrow" requires too much hand motion while coding. And finally, is there anyway I can map this to "SHIFT+Space"?

• Optimizing GDI+ drawing?

  - by user146780

  I'm using C++ and GDI+ I'm going to be making a vector drawing application and want to use GDI+ for the drawing. I'v created a simple test to get familiar with it: case WM_PAINT: GetCursorPos(&mouse); GetClientRect(hWnd,&rct); hdc = BeginPaint(hWnd, &ps); MemDC = CreateCompatibleDC(hdc); bmp = CreateCompatibleBitmap(hdc, 600, 600); SelectObject(MemDC,bmp); g = new Graphics(MemDC); for(int i = 0; i < 1; ++i) { SolidBrush sb(Color(255,255,255)); g->FillRectangle(&sb,rct.top,rct.left,rct.right,rct.bottom); } for(int i = 0; i < 250; ++i) { pts[0].X = 0; pts[0].Y = 0; pts[1].X = 10 + mouse.x * i; pts[1].Y = 0 + mouse.y * i; pts[2].X = 10 * i + mouse.x; pts[2].Y = 10 + mouse.y * i; pts[3].X = 0 + mouse.x; pts[3].Y = (rand() % 600) + mouse.y; Point p1, p2; p1.X = 0; p1.Y = 0; p2.X = 300; p2.Y = 300; g->FillPolygon(&b,pts,4); } BitBlt(hdc,0,0,900,900,MemDC,0,0,SRCCOPY); EndPaint(hWnd, &ps); DeleteObject(bmp); g->ReleaseHDC(MemDC); DeleteDC(MemDC); delete g; break; I'm wondering if I'm doing it right, or if I have areas killing the cpu. Because right now it takes ~ 1sec to render this and I want to be able to have it redraw itself very quickly. Thanks In a real situation would it be better just to figure out the portion of the screen to redraw and only redraw the elements withing bounds of this?

• Android layout issue - table/grid/linear

  - by phpmysqlguy

  I am trying to wrap my head around some basic layout issues in android. Here is what I want as my final goal: As you can see, various fields set up like that. The fields get filled in based on XML data. There could be 1 set of fields, or there could be more. I tried a tablelayout, but couldn't get it set up right even when layout_span for Field 7. It worked ok, but when I tried to change the widths of Field 1 thru 5, the spanned row below it didn't conform to the changes (not like an HTML table would). The fields in each group need to lineup if there are more than one (see red lines in image). Can someone point me in the right direction on how I should approach this? Thanks

• Version control PHP Web Project

  - by Adam Lerman

  We have a php project that we would like to version control. Right now there are three of us working on a "Dev" version of the project that all have our Eclipse linked to it with just an external folder, and thus no version control. What is the right way, and what is the best way, to version control this (not necessarily the same I dont think) We have a SVN set up but just need to find a good way to check in and check out that lets us test on the dev server. Any ideas?

• How do I add items to the Finder context menu in Mac OS X?

  - by mystro

  I'm in the process of porting a Windows application to OS X (we wrote it in Java so most of the code is portable), but what I'm currently unsure of is how to add context menu items in the Finder window when the user right clicks on an item (i.e. I wish to add some items to the the menu that has "Open" "Open with" , "Get Info", etc... when the user right clicks). Most of the articles I've found deal specifically with Windows (I've searched for "context menus" and "shell extension", but I believe I may be searching the wrong terms), so I'm curious as to how to go about adding this in Mac or what literature I should be reading.

• BST Level Traversal

  - by Dalton Conley

  Ok, so I'm trying to do a level order traversal of a binary search tree and its not working. The code below makes sense to me, but that is probably because I've been looking at it forever and I've convinced myself that it should work. void BST<T>::levelByLevel(ostream &out) { Queue<BinNodePointer> q; BinNodePointer subtreeRoot; if(myRoot == NULL) return; q.enqueue(myRoot); while(!q.empty()) { subtreeRoot = q.front(); out << subtreeRoot->data << " "; q.dequeue(); if(subtreeRoot->left != NULL) q.enqueue(subtreeRoot->left); if(subtreeRoot->right != NULL) q.enqueue(subtreeRoot->right); } } Maybe you guys could point out what I'm doing wrong because, although I understand the concept of a binary search tree, I'm not 100% on all the ins and outs.

• pre tag is being formatted strangely in page

  - by morpheous

  I am outputting some code in one of my pages, using a <pre> tag. The code is being output correctly, but for some strange reason, the first line of the code is indented (i.e. shifted to the right, by quite a large amount). I am not applying any style to that element, and I checked in FF Firebug and no styling is being applied, so I have no idea why the first line is shifted by so much to the right - any ideas? the code that generates the tag looks like this: <pre> <?php echo $script_code; ?> </pre> The generated code looks like this: <iframe src="http://www.example.com"> </iframe> Any ideas what may be going wrong?

• Tidying up a list

  - by Jonas

  I'm fairly sure there should be an elegant solution to this (in Matlab), but I just can't think of it right now. I have a list with [classIndex, start, end], and I want to collapse consecutive class indices into one group like so: This 1 1 40 2 46 53 2 55 55 2 57 64 2 67 67 3 68 91 1 94 107 Should turn into this 1 1 40 2 46 67 3 68 91 1 94 107 How do I do that? EDIT Never mind, I think I got it - it's almost like fmarc's solution, but gets the indices right a=[ 1 1 40 2 46 53 2 55 55 2 57 64 2 67 67 3 68 91 1 94 107]; d = diff(a(:,1)); startIdx = logical([1;d]); endIdx = logical([d;1]); b = [a(startIdx,1),a(startIdx,2),a(endIdx,3)];

• Printing contents of a dynamically created iframe from parent window

  - by certainlyakey

  I have a page with a list of links and a div which serves as a placeholder for the pages the links lead to. Everytime user clicks on a link an iframe is created in the div and its src attribute gets the value of the link href attribute - simple and clear, sort of external web pages gallery. What i do have a problem with is printing the contents of the iframe. To do this i use this code: function PrintIframe() { frames["name"].focus(); frames["name"].print(); } The issue seems to be that iframe is created dynamically by JQuery - when I insert an iframe right into the html code, the browser prints the external page all right. But with the same code injected by JavaScript nothing happens. I tried to use JQ 1.3 'live' event on "Print" link, no success. Is there a way to overcome this?

• PHP: Auto Updating subscriptions?

  - by Duncan Palmer

  Hey guys I am currently making a website and I am hopefully going to start a premium service for it. What I am currently looking into right now is how to make an "auto updating" shop which removes 1 day from how many days left the user has left on their premium status. so for example if the users purchases 30 days of premium, each day that 30 with negate 1 so.. 30, 29, 28, 27.. etc and then if the days gets to 0 in will remove premium status. The only way I can think of keeping track of this right now is by manually monitoring each persons premium status but that wouldnt be very practical. What would the best way for me to do this? (hopefully "automatically") Thanks.

• OpenGL ES perspective projection

  - by TimeManx

  I'm having a hard time understanding how glFrustum & gluPerspective work. I understand the concept of perspective projection but the functions aren't behaving how I expect them to. For example, if I set the frustum this way glFrustumf(0, 10, 0, 10, 1, 100) and have a rectangle at points 0, 0, 1, 0, 10, 1, 10, 10, 1, 10, 0, 1 then the rectangle is drawn with its left edge at -5 & right edge at 5, so the left half of the rectangle isn't visible. And if x is translated, I'd expect y to be too. But that doesn't happen either. In whatever examples I've seen, the coordinates for the projection matrix are taken as glFrustumf(-10, 10, -10, 10, 1, 100) but either way, whatever part is shown should be dependent on the rectangle's coordinates, right?

• What would be the best approach for this?

  - by chobo

  I have a site which has an area that requires authentication. Right now I use the roles attribute on all the controllers in that area, and I run a query to retrieve that users ID, and all their settings. It seems like a code or design smell to me that I am retrieving the userid and settings each time a controller in that area loads up? I'm not sure if I should be using sessions, or if ASP.Net MVC 2.0 provides some unique way to handle this. Another concern is security. Overall, I don't really know which way to turn. Design wise I would like the userId and settings retrieved only once when the user logs into the area. Right now I grab the userId each time a controller loads up, and then if required, I query the database for their settings each time as well.

• php: parsing and converting array structure

  - by mwb

  I need to convert one array structure into another array structure. I hope someone will find it worthy their time to show how this could be done in a simple manner. It's a little above my array manipulation skills. The structure we start out with looks like this: $cssoptions = array( array( 'group' => 'Measurements' , 'selector' => '#content' , 'rule' => 'width' , 'value' => '200px' ) // end data set , array( 'group' => 'Measurements' , 'selector' => '#content' , 'rule' => 'margin-right' , 'value' => '20px' ) // end data set , array( 'group' => 'Colors' , 'selector' => '#content' , 'rule' => 'color' , 'value' => '#444' ) // end data set , array( 'group' => 'Measurements' , 'selector' => '.sidebar' , 'rule' => 'margin-top' , 'value' => '10px' ) // end data set ); // END $cssoptions It's a collection of discreet datasets, each consisting of an array that holds two key = value pairs describing a 'css-rule' and a 'css-rule-value'. Further, each dataset holds a key = value pair describing the 'css-selector-group' that the 'css-rule' should blong to, and a key = value pair describing a 'rule-group' that should be used for structuring the rendering of the final css into a neat css code block arranged by the kind of properties they describe (colors, measurement, typography etc..) Now, I need to parse that, and turn it into a new structure, where the: 'rule' => 'rule-name' , 'value' => 'value-string' for each dataset is converted into: 'rule-name' => 'value-string' ..and then placed into a new array structure where all 'rule-name' = 'value-string' pairs should be aggregated under the respective 'selector-values' Like this: '#content' => array( 'width' => '200px' , 'margin-right' => '20px' ) // end selecor block ..and finally all those blocks should be grouped under their respective 'style-groups', creating a final resulting array structure like this: $css => array( 'Measurements' => array( '#content' => array( 'width' => '200px' , 'margin-right' => '20px' ) // end selecor block , '.sidebar' => array( 'margin-top' => '10px' ) // end selector block ) // end rule group , 'Colors' => array( '#content' => array( 'color' => '#444' ) // end selector block ) // end rule group ); // end css
