  • CSS - margin and float property

    - by David Casillas
    1.- We have a div with static positioning. Inside we have a parragraph with a margin. The heigth of the div will be the parragraph without the margin 2.- We have a div with float:left. Inside we have a parragraph with a margin. The heigth of the div will be the parragraph plus its margin. What is the explanation of this? Here is the html code and the CSS code. And here is a link to the test site. http://prueba.davidcasillas.es/ <!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="es"> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <title>Untitled Document</title> <link href="index.css" rel="stylesheet" type="text/css" /> </head> <body> <div id="nivel1"> <div id="nivel21"> <p>Este es el primer parrafo</p> </div> <div id="nivel22"> <p>Este es el primer parrafo</p> </div> </div> </body> </html> body { margin:0; padding:0; } #nivel1 { border:solid; border-color:#333; margin:0; background-color:#0F3; margin:2em; } #nivel21 { margin:2em; float:left; background-color:#C00; } #nivel22 { margin:2em; background-color:#FC0; }

  • Anchor tag not centered on page after clicking

    - by jennyjune
    I am creating a website that scrolls down to different divs by the use of anchors. However, when I click on a link, that anchored div is not centered on the page. I positioned my divs absolutely but I have no idea if that is affecting it? Anyone have any clue how to get the divs centered using anchors?

  • My ashx stopped working (Works locally, but not online)

    - by Madi D.
    i have a simple ASHX file that returns pictures upon request (mainly a counter), previously the code simply fetched pre-made pictures(already uploaded and available) and sent them to the requester.. i just modified the code,so it would take a base picture, do some modifications on it, save it to the server, then serve it to the user.. tested it locally and it worked like a charm. however when i uploaded the code to my hosting service (Godaddy..) it didnt work. Can someone point the problem out to me? Note: ASHX worked with me before,so i know the web.config and IIS are handling them properly, however i think i am missing something .. Code: <%@ WebHandler Language="C#" Class="NWEmpPhotoHandler" %> using System; using System.Web; using System.IO; using System.Drawing; using System.Drawing.Imaging; public class NWEmpPhotoHandler : IHttpHandler { public bool IsReusable { get { return true; } } public void ProcessRequest(HttpContext ctx) { try { //Some Code to fetch # of vistors from DB int x = 10,000; // # of Vistors, fetched from DB string numberOfVistors = (1000 + x).ToString(); string filePath = ctx.Server.MapPath("counter.jpg"); Bitmap myBitmap = new Bitmap(filePath); Graphics g = Graphics.FromImage(myBitmap); g.TextRenderingHint = System.Drawing.Text.TextRenderingHint.AntiAlias; StringFormat strFormat = new StringFormat(); g.DrawString(numberOfVistors , new Font("Tahoma", 24), Brushes.Maroon, new RectangleF(55, 82, 500, 500),null); string PathToSave = ctx.Server.MapPath("counter-" + numberOfVistors + ".jpg"); saveJpeg(PathToSave, myBitmap, 100); if (File.Exists(PathToSave)) { ctx.Response.ContentType = "image/jpg"; ctx.Response.WriteFile(PathToSave); //ctx.Response.OutputStream.Write(picByteArray, 0, picByteArray.Length); } } catch (ArgumentException exe) { } } private ImageCodecInfo getEncoderInfo(string mimeType) { // Get image codecs for all image formats ImageCodecInfo[] codecs = ImageCodecInfo.GetImageEncoders(); // Find the correct image codec for (int i = 0; i < codecs.Length; i++) if (codecs[i].MimeType == mimeType) return codecs[i]; return null; } private void saveJpeg(string path, Bitmap img, long quality) { // Encoder parameter for image quality EncoderParameter qualityParam = new EncoderParameter(Encoder.Quality, quality); // Jpeg image codec ImageCodecInfo jpegCodec = this.getEncoderInfo("image/jpeg"); if (jpegCodec == null) return; EncoderParameters encoderParams = new EncoderParameters(1); encoderParams.Param[0] = qualityParam; img.Save(path, jpegCodec, encoderParams); } }

  • NSTableView get rid blank space separating columns

    - by Matt S.
    I have an NSTableView with 4 columns. I also have a custom background color for each row. The only problem is I have these ugly white spaces where the gridlines would go in both the horizontal and vertical axis. I have both unchecked in IB, but they still show up. How can I get rid of the vertical ones and change the color and size of the horizontal ones? Here's what I see:

  • UIButton not firing selector if I draw it using CALayer

    - by Horatiu Paraschiv
    Hi everybody I create this button like this: _myButton = [[UIButton buttonWithType:UIButtonTypeCustom] retain]; DLBadgeLayerDelegate *layerDelegate = [[DLBadgeLayerDelegate alloc] init]; _myButton.frame = CGRectMake(0.0 , 0.0, 100.0, 100.0); [_myButton addTarget:self action:@selector(myButtonTapped:) forControlEvents:UIControlEventTouchUpInside]; _myButton.layer.backgroundColor = [[UIColor redColor] CGColor]; _myButton.center = CGPointMake(10.0, 10.0); [self addSubview:_myButton]; [_myButton release]; The button appears on the screen but if I tap on it nothing happens. If I just create a Rounded rect button instead with no custom drawing on its layer or if I just leave the layer line of code out all works well. Do you have any Idea why do I get this behaviour as I would like to do some custom drawing in the button's layer?

    consider this piece of scala swing code detail.reactions +={ case ButtonClicked(but) = detail.contents += new Label(but.text) detail.background = new java.awt.Color(0,255,0) } the detail is of FlowPanel type. When the button is clicked, the color is instantly repainted, but the Label is not. It gets visible as I click the area. How can I force the detail to repaint its contents after a click?

  • Galleria jQuery plugin briefly shows all images in IE 7 & 8

    - by hollyb
    I'm using the galleria jQuery plugin on a site. When the gallery first loads, all of the images appear briefly & vertically in ie 7 & 8. This doesn't happen when i isolate the gallery, only when i put it on a somewhat heavy page. This leads me to believe that it happens when the page is a little slow to load. Does anybody know a way to fix this? I feel like an overflow: hidden should fix this, but I've applied it along with a height in every container I could think of. Anybody have any ideas? Here is my css: .galleria{list-style:none;width:350px; overflow:hidden; height: 70px;} .galleria li{display:block;width:50px;height:50px;overflow:hidden;float:left;margin:4px 10px 20px 0;} .galleria li a{display:none;} .galleria li div{position:absolute;display:none;top:0;left:180px;} .galleria li div img{cursor:pointer;} .galleria li.active div img,.galleria li.active div{display:block;} .galleria li img.thumb{cursor:pointer;top:auto;left:auto;display:block;width:auto;height:auto} .galleria li .caption{display: inline;padding-top:.5em; width: 300px; } * html .galleria li div span{width:350px;} /* MSIE bug */ html: <ul class="gallery"> <li class="active"><img src="1.jpg" cap="A great veiw by so and so.

  • Android: 2D. OpenGl or android.graphics?

    - by DroidIn.net
    I'm working with my friend on our first Android game. Basic idea is that every frame the whole surface is redrawn (1 large bitmap) which then sprinkled all over with large number of particles which produces effect of soapy bubbles where there's a pool of about 20 bitmaps which randomly gets picked to produce illusion that all bubbles (between 200 - 300) are all different. The math engine is in C (JNI) and currently all drawing is done using android.graphics package very similar (since that was the example I was using) to Lunar Lander. It works but animation is somewhat jerky and I can feel by temperature of my phone that it is very busy. Will we benefit from switching to OpenGL? And as a bonus question: what would be a good way to optimize the drawing mechanism (Lunar Lander like) we have now?

  • Converting to async,await using async targeting package

    - by e4rthdog
    I have this: private void BtnCheckClick(object sender, EventArgs e) { var a = txtLot.Text; var b = cmbMcu.SelectedItem.ToString(); var c = cmbLocn.SelectedItem.ToString(); btnCheck.BackColor = Color.Red; var task = Task.Factory.StartNew(() => Dal.GetLotAvailabilityF41021(a, b, c)); task.ContinueWith(t => { btnCheck.BackColor = Color.Transparent; lblDescriptionValue.Text = t.Result.Description; lblItemCodeValue.Text = t.Result.Code; lblQuantityValue.Text = t.Result.AvailableQuantity.ToString(); },TaskScheduler .FromCurrentSynchronizationContext() ); LotFocus(true); } and i followed J. Skeet's advice to move into async,await in my .NET 4.0 app. I converted into this: private async void BtnCheckClick(object sender, EventArgs e) { var a = txtLot.Text; var b = cmbMcu.SelectedItem.ToString(); var c = cmbLocn.SelectedItem.ToString(); btnCheck.BackColor = Color.Red; JDEItemLotAvailability itm = await Task.Factory.StartNew(() => Dal.GetLotAvailabilityF41021(a, b, c)); btnCheck.BackColor = Color.Transparent; lblDescriptionValue.Text = itm.Description; lblItemCodeValue.Text = itm.Code; lblQuantityValue.Text = itm.AvailableQuantity.ToString(); LotFocus(true); } It works fine. What confuses me is that i could do it without using Task but just the method of my Dal. But that means that i must have modified my Dal method, which is something i dont want? I would appreciate if someone would explain to me in "plain" words if what i did is optimal or not and why. Thanks P.s. My dal method public bool CheckLotExistF41021(string _lot, string _mcu, string _locn) { using (OleDbConnection con = new OleDbConnection(this.conString)) { OleDbCommand cmd = new OleDbCommand(); cmd.CommandText = "select lilotn from proddta.f41021 " + "where lilotn = ? and trim(limcu) = ? and lilocn= ?"; cmd.Parameters.AddWithValue("@lotn", _lot); cmd.Parameters.AddWithValue("@mcu", _mcu); cmd.Parameters.AddWithValue("@locn", _locn); cmd.Connection = con; con.Open(); OleDbDataReader rdr = cmd.ExecuteReader(); bool _retval = rdr.HasRows; rdr.Close(); con.Close(); return _retval; } }

  • JMenuBar dropping down to a "custom" JPanel and "erased"

    - by Jani
    The JMenuItems of JMenuBar drops down to a JPanel added to the JFrame, but the JPanel erases the JMenuItems. Do I supposed to pause the re-drawing of the JPanel? I'm using getGraphics() on the JPanel for drawing an image, this method is called from a thread with (for example) 200 ms delay. edit: It's a (very simple) game inside the JPanel. (I've added a field "paused" to the JPanel and i've edited the paint method so it repaints the JPanel only if paused is false, however I don't know if this "solution" is good. (It's set to true when the user clicks on a menu and set to false when selects or cancels it.)

  • NSOperation and UIKit problem

    - by Infinity
    Hello guys! I am doing my download with an object which was inherited from NSOperation. I have read the documentation and when my operation finished I must call the [self.delegate performSelectorOnMainThread:@selector(operationDidFinish:) withObject:self waitUntilDone:YES]; method. It needs to be called on the main thread, because the UIKit is not thread safe and the documentation says this in these non thread safe frameworks cases. In the delegate method I am drawing a pdf or an image, but because it is drawn on the main thread the User Interface is very laggy until the drawing is finished. Maybe can you suggest me a good way to avoid this problem?

    Hi, I've tried to strip html tags using regex replace with pattern "<[^]*" from word generated html that looks like this: <html xmlns:v="urn:schemas-microsoft-com:vml" xmlns:o="urn:schemas-microsoft-com:office:office" xmlns:w="urn:schemas-microsoft-com:office:word" xmlns:st1="urn:schemas-microsoft-com:office:smarttags" xmlns="http://www.w3.org/TR/REC-html40"> <head> <meta http-equiv=Content-Type content="text/html; charset=iso-8859-2"> <meta name=Generator content="Microsoft Word 11 (filtered medium)"> <!--[if !mso]> <style> v\:* {behavior:url(#default#VML);} o\:* {behavior:url(#default#VML);} w\:* {behavior:url(#default#VML);} .shape {behavior:url(#default#VML);} </style> <![endif]--><o:SmartTagType namespaceuri="urn:schemas-microsoft-com:office:smarttags" name="place" downloadurl="http://www.5iantlavalamp.com/"/> <!--[if !mso]> <style> st1\:*{behavior:url(#default#ieooui) } </style> <![endif]--> <style> <!-- /* Font Definitions / @font-face {font-family:Tahoma; panose-1:2 11 6 4 3 5 4 4 2 4;} / Style Definitions */ p.MsoNormal, li.MsoNormal, div.MsoNormal {margin:0in; margin-bottom:.0001pt; font-size:12.0pt; font-family:"Times New Roman";} a:link, span.MsoHyperlink {color:blue; text-decoration:underline;} a:visited, span.MsoHyperlinkFollowed {color:purple; text-decoration:underline;} span.EmailStyle17 {mso-style-type:personal; font-family:Arial; color:windowtext;} span.EmailStyle18 {mso-style-type:personal-reply; font-family:Arial; color:navy;} @page Section1 {size:8.5in 11.0in; margin:1.0in 1.25in 1.0in 1.25in;} div.Section1 {page:Section1;} --> </style> </head> Everything works fine except for the bolded lines above, anybody got ideas how to match the them to? Thanks, Aleksandar

  • Rails + AMcharts (with export image php script) - PHP script converted to controller?

    - by Elliot
    Hey Guys, This one might be a little confusing. I'm using AMCharts with rails. Amcharts comes with a PHP script to export images called "export.php" I'm trying to figure out how to take the code in export.php and put it into a controller. Here is the code: <?php // amcharts.com export to image utility // set image type (gif/png/jpeg) $imgtype = 'jpeg'; // set image quality (from 0 to 100, not applicable to gif) $imgquality = 100; // get data from $_POST or $_GET ? $data = &$_POST; // get image dimensions $width = (int) $data['width']; $height = (int) $data['height']; // create image object $img = imagecreatetruecolor($width, $height); // populate image with pixels for ($y = 0; $y < $height; $y++) { // innitialize $x = 0; // get row data $row = explode(',', $data['r'.$y]); // place row pixels $cnt = sizeof($row); for ($r = 0; $r < $cnt; $r++) { // get pixel(s) data $pixel = explode(':', $row[$r]); // get color $pixel[0] = str_pad($pixel[0], 6, '0', STR_PAD_LEFT); $cr = hexdec(substr($pixel[0], 0, 2)); $cg = hexdec(substr($pixel[0], 2, 2)); $cb = hexdec(substr($pixel[0], 4, 2)); // allocate color $color = imagecolorallocate($img, $cr, $cg, $cb); // place repeating pixels $repeat = isset($pixel[1]) ? (int) $pixel[1] : 1; for ($c = 0; $c < $repeat; $c++) { // place pixel imagesetpixel($img, $x, $y, $color); // iterate column $x++; } } } // set proper content type header('Content-type: image/'.$imgtype); header('Content-Disposition: attachment; filename="chart.'.$imgtype.'"'); // stream image $function = 'image'.$imgtype; if ($imgtype == 'gif') { $function($img); } else { $function($img, null, $imgquality); } // destroy imagedestroy($img); ?>

  • Works in Google charts but not in Eastwood?

    - by Rhubarb
    This chart works fine in Google charts, but when rendered in Eastwood, it doesn't use the 2nd provided color, rather it applies the first color to both bars in the chart. http://chart.apis.google.com/chart?cht=bvg&chs=150x150&chd=t:18,81&chco=FFF000|00FFFF&chxt=x,y&chl=Bar1|Bar2&chtt=Chart Any suggestions as to why this could be? Unfortunately it looks like Eastwood is somewhat abandoned.

  • Java library for CSS cleanup

    - by ndn
    For a rich text editor that has to handle pasted HTML code from MS Office applications, I'm looking for a Java library that cleans up the content of all "style" attributes in HTML elements, so that only some CSS attributes are left: background-color border color font-family font-weight font-style list-style-type text-align text-decoration vertical-align For creating a well-formed HTML document, I can use JTidy. For HTML element transformations (removing unwanted elements), I can use http://htmlparser.sourceforge.net/ Is there anything comparable for CSS attributes?
