  • HTML table with auto-fit for some columns, fixed width for others

    - by sangil
    I'm trying to create a table adhering to the following requirements: The table width must be defined as 0 - the browser should calculate the width according to the column widths (this is to accommodate a column-resize plugin). Some columns may receive a fixed width (e.g. 50px); Columns that do not receive a fixed width, must auto-fit to the content. I have created a small example to illustrate the problem - as you can see column 3 stays at width 0 and so is not visible. HTML <table> <tr> <td class="cell header" id="header1">Header 1</td> <td class="cell header" id="header2">Header 2</td> <td class="cell header" id="header3">Header 3</td> </tr> <tr> <td class="cell">Cell 1</td> <td class="cell">Cell 2</td> <td class="cell">Very looooong content</td> </tr> </table> CSS table { table-layout: fixed; width: 100%; border: 1px solid #696969; } .cell { color: #898989; border: 1px solid #888; padding: 2px; overflow: hidden; } .header { background-color: lightsteelblue; color: black; } #header1, #header2 { width: 50px; } Is this even possible? Any help would be appreciated...

  • Initializing Disqus comments in hidden element causes issue in FF 14.0.1

    - by Bazze
    This issue appears only in Firefox 14.0.1 (well I couldn't reproduce it in any other browser). If you put the code for Disqus comments inside an element that is hidden and wait until everything is fully loaded and then display the element using JavaScript, the comment box nor comments will show up. However if you resize the window, it'll show up immediately. It's working fine in latest version of Google Chrome and Safari though. What's causing this and how to fix it? Sample code to reproduce: <div id="test" style="display:none;"> <div id="disqus_thread"></div> <script type="text/javascript"> /* * * CONFIGURATION VARIABLES: EDIT BEFORE PASTING INTO YOUR WEBPAGE * * */ var disqus_shortname = 'onlinefunctions'; // required: replace example with your forum shortname /* * * DON'T EDIT BELOW THIS LINE * * */ (function() { var dsq = document.createElement('script'); dsq.type = 'text/javascript'; dsq.async = true; dsq.src = 'http://' + disqus_shortname + '.disqus.com/embed.js'; (document.getElementsByTagName('head')[0] || document.getElementsByTagName('body')[0]).appendChild(dsq); })(); </script> <noscript>Please enable JavaScript to view the <a href="http://disqus.com/?ref_noscript">comments powered by Disqus.</a></noscript> <a href="http://disqus.com" class="dsq-brlink">comments powered by <span class="logo-disqus">Disqus</span></a> </div> <a href="#" onclick="document.getElementById('test').style.display = 'block'">show</a> I could post a link to a live example but I'm not sure about the policy of posting links here on Stack Overflow.

  • How to determine the width of content or size a container to content

    - by ISVK
    My goal is to display the entire contents of a FlowDocument (that is, without paginating) in a column layout. It would have a fixed height, but the width would depend on the contents of the FlowDocument. My problem is: FlowDocumentReader does not automatically resize to the contents of the FlowDocument. As you see in my XAML below, FlowDocumentReader.Width is 5000 units (just a large number that can accommodate most documents) -- when I make it Auto, it just clips to the width of the ScrollViewer and paginates my stuff! Is there a proper way of solving this problem? I also made a screenshot of what this looks like now, but the ScrollViewer scrolls past the end of the document in most cases: http://i.imgur.com/3FSRl.png <ScrollViewer x:Name="scrollViewer" HorizontalScrollBarVisibility="Visible" VerticalScrollBarVisibility="Disabled" > <FlowDocumentReader x:Name="flowDocReader" ClipToBounds="False" Width="5000" > <FlowDocument x:Name="flowDoc" Foreground="#FF404040" ColumnRuleWidth="2" ColumnGap="40" ColumnRuleBrush="#FF404040" IsHyphenationEnabled="True" IsOptimalParagraphEnabled="True" ColumnWidth="150"> <Paragraph> Lorem ipsum dolor sit amet, ...etc... </Paragraph> <Paragraph> Lorem ipsum dolor sit amet, ...etc... </Paragraph> <Paragraph> Lorem ipsum dolor sit amet, ...etc... </Paragraph> </FlowDocument> </FlowDocumentReader> </ScrollViewer>

  • STL vectors with uninitialized storage?

    - by Jim Hunziker
    I'm writing an inner loop that needs to place structs in contiguous storage. I don't know how many of these structs there will be ahead of time. My problem is that STL's vector initializes its values to 0, so no matter what I do, I incur the cost of the initialization plus the cost of setting the struct's members to their values. Is there any way to prevent the initialization, or is there an STL-like container out there with resizeable contiguous storage and uninitialized elements? (I'm certain that this part of the code needs to be optimized, and I'm certain that the initialization is a significant cost.) Also, see my comments below for a clarification about when the initialization occurs. SOME CODE: void GetsCalledALot(int* data1, int* data2, int count) { int mvSize = memberVector.size() memberVector.resize(mvSize + count); // causes 0-initialization for (int i = 0; i < count; ++i) { memberVector[mvSize + i].d1 = data1[i]; memberVector[mvSize + i].d2 = data2[i]; } }

  • Global mouseMove

    - by Jacob Kofoed
    I have made the following javascript to be used in my jQuery based website. What it does, is to move a slider up/down, and scale the item above higher/smaller. Everything works fine, but since the slider is only a few pixels in height, and the move event is a bit slow (it does not trigger for every pixel) so when I move the mouse fast, the slider can't hold on and the mouse get's out of the slider item. The mouseMove event won't be triggered no more since it is bound to the slider. I guess everything could be fixed by setting the mouseMove global to the whole site, but it won't work, or at least I don't know how to make that work. Should it be bound to document, or body? here is my current code for the slider: $.fn.resize = function (itemToResize) { MinSize = 100; MaxSize = 800; pageYstart = 0; sliderMoveing = false; nuskriverHeight = 0; this.mousedown(function(e) { pageYstart=e.pageY; sliderMoveing = true nuskriverHeight = parseFloat((itemToResize).css('height')); }); this.mouseup(function() { sliderMoveing = false }); this.mousemove(function(e) { if (sliderMoveing) { (itemToResize).css('height', (nuskriverHeight + (e.pageY - pageYstart))); if (parseFloat( (itemToResize).css('height')) > MaxSize) { (itemToResize).css('height', MaxSize) }; if (parseFloat( (itemToResize).css('height')) < MinSize) { (itemToResize).css('height', MinSize) }; }; }); }; Thanks for any help, is much appreciated

  • Thumbnail image saved with worse quality on Windows Server 2003

    - by Angelo
    Hello, In asp.net 2.0 application I am trying to create thumbnails from uploaded images. However when I test the application on my PC under Windows7 it works fine, but on the real Windows 2003 Server the resized image has worse quality. Where this difference could come from? Different JPEG codec or what, if Yes how it can be updated on Win 2003 Server? Thanks! Here is the code: Resize of the Image: Bitmap newBmp = new Bitmap(imgWidth, imgHeight, PixelFormat.Format24bppRgb); newBmp.SetResolution(inputBmp.HorizontalResolution, inputBmp.VerticalResolution); //Create a graphics object attached to the new bitmap Graphics newBmpGraphics = Graphics.FromImage(newBmp); newBmpGraphics.InterpolationMode = InterpolationMode.HighQualityBicubic; newBmpGraphics.SmoothingMode = SmoothingMode.HighQuality; newBmpGraphics.PixelOffsetMode = PixelOffsetMode.HighQuality; newBmpGraphics.DrawImage(inputBmp, new Rectangle(0, 0, imgWidth, imgHeight), new Rectangle(0, 0, inputBmp.Width, inputBmp.Height), GraphicsUnit.Pixel); Save of the Image: System.IO.Stream imgStream = new System.IO.MemoryStream(); //Get the ImageCodecInfo for the desired target format ImageCodecInfo destCodec = FindCodecForType(ImageMimeTypes.JPEG); if (destCodec == null) { //No codec available for that format throw new ArgumentException("The requested format image/jpeg does not have an available codec installed", "destFormat"); } //Create an EncoderParameters collection to contain the //parameters that control the dest format's encoder EncoderParameters destEncParams = new EncoderParameters(1); EncoderParameter qualityParam = new EncoderParameter(System.Drawing.Imaging.Encoder.Quality,(long)quality); destEncParams.Param[0] = qualityParam; //Save w/ the selected codec and encoder parameters inputBmp.Save(imgStream, destCodec, destEncParams); Bitmap destBitmap = new Bitmap(imgStream);

  • Invalid Argument javascript error only on certain computers

    - by Jen
    Getting an error whenever we click a particular button/link on our site. It is generating a javascript "Invalid Argument" error. I know in the other posts it is typically because it is a syntax error in the javascript however it only just seems to have started happening and it doesn't happen on all pcs. ie. in our client's environment if I remote onto their web server and view the uat website I get the javascript error. If I remote onto their sql server and view the uat website I don't get the javascript error. If it was a syntax error then I would always get the error wouldn't I? both browsers are the same version of IE6 (yeah I know...) :) I have tried deleting temporary internet files - including viewing the files and deleting them myself - but no joy. client uses citrix.. and they're all getting the error :( Any ideas would be appreciated - Thanks! :) Update - Sorry I haven't posted specific code as there is too much to post (and I'm not sure where the error is occurring). The "button" launches a new window which in turn opens up a couple of aspx pages and calls lots of javascript. So the window opens ok, and there's a function that gets called to resize the window - but before it calls the resizing of the window/content it throws the invalid argument error. Am busy trying to get alerts to trigger to see if I can see where it's falling over but so far no luck. Again not sure why this error doesn't occur when I use a particular PC (same browser version)

  • Image Resizing and Compression

    - by GSTAR
    Hi guys, I'm implementing an image upload facility for my website. The uploading facility is complete but what I'm working on at the moment is manipulating the images. For this task I am using PHPThumb (http://phpthumb.gxdlabs.com). Anyway as I go along I'm coming across potential issues, to do with resizing and compression. Basically I want to acheive the following results: The ideal image dimensions are: 800px width, 600px height. If an uploaded image exceeds either of these dimensions, it will need be resized to meet the requirements. Otherwise, leave as it is. The ideal file size is 200kb. If an uploaded image exceeds this then it will need to be compressed to meet this requirement. Otherwise, leave as it is. So in a nutshell: 1) Check the dimensions, resize if required. 2) Check the filesize, compress if required. Has anybody done anything like this / could you give me some pointers? Is PHPThumb the correct tool to do this in?

  • Is there unresizable space in latex? Pictures in good looking grid.

    - by drasto
    I've created latex macro to typeset guitar chords diagrams(using picture environment). Now I want to make diagrams of different appear in good looking grid when typeset one next to each other as the picture shows: The picture. (on the picture: Labeled "First" bad layout of diagrams, labeled "Second" correct layout when equal number of diagrams in line) I'm using \hspace to make some skips between diagrams, otherwise they would be too near to each other. As you can see in second case when latex arrange pictures in so that there is same number of them in each line it works. However if there is less pictures in the last line they become "shifted" to the right. I don't want this. I guess is because latex makes the space between diagrams in first line a little longer for the line to exactly fit the page width. How do I tell latex not to resize spaces created by \hspace ? Or is there any other way ? I guess I cannot use tables because I don't know how many diagrams will fit in one line... This is current state of code: \newcommand{\spaceForChord}{1.7cm} \newcommnad{\chordChart}[1]{% %calculate dimensions xdim and ydim according to setings \begin{picture}(xdim, ydim){% %draw the diagram inside defined area }% \hspace*{\spaceForChord}% \hspace*{-\xdim}% }% %end preambule and begin document \begin{document} First:\\* \\* \chordChart{...some arguments for to change diagram look...} \chordChart{...some arguments for to change diagram look...} \chordChart{...some arguments for to change diagram look...} \chordChart{...some arguments for to change diagram look...} \chordChart{...some arguments for to change diagram look...} %...above line is repeated 12 more times to produce result shown at the picture \end{document} Thanks for any help.

  • CSS/Javascript: multiple columns

    - by Patrick
    hi, I'm looking for a columnizer plugin (making columns of my small divs). It is very important it has the following features: 1) It has to be as light as possible (if it is only css would be great, but I guess it is difficult make it work on IE then...) 2) It has to be cross-browser (I don't need IE6... IE7 and IE8 compatibility is required). 3) The divs has not to be broken. In other terms, the nodes have to be moved to next block but not splitted in 2. The nodes are div elements, they might include other divs, images and text. 4) The column have to have a fixed width and fixed margin. This means that when I resize the browser, and new columns are created (become the window becomes wider), the new columns have to rigidly keep the same width and distance between them. (margin:20px) (width:200px) Would be great to have some css.. but I'm afraid I need some jQuery plugin because I need all 4 features being supported. I found several plugins and css styleshits with very good solutions, but I couldn't find a complete one. Thanks

  • Regex Replacing only whole matches

    - by Leen Balsters
    I am trying to replace a bunch of strings in files. The strings are stored in a datatable along with the new string value. string contents = File.ReadAllText(file); foreach (DataRow dr in FolderRenames.Rows) { contents = Regex.Replace(contents, dr["find"].ToString(), dr["replace"].ToString()); File.SetAttributes(file, FileAttributes.Normal); File.WriteAllText(file, contents); } The strings look like this _-uUa, -_uU, _-Ha etc. The problem that I am having is when for example this string "_uU" will also overwrite "_-uUa" so the replacement would look like "newvaluea" Is there a way to tell regex to look at the next character after the found string and make sure it is not an alphanumeric character? I hope it is clear what I am trying to do here. Here is some sample data: private function _-0iX(arg1:flash.events.Event):void { if (arg1.type == flash.events.Event.RESIZE) { if (this._-2GU) { this._-yu(this._-2GU); } } return; } The next characters could be ;, (, ), dot, comma, space, :, etc.

  • Expanders inside listbox leaving blank space on collapse

    - by siz
    We have a rather complex UI that is presenting some problems for us. I have a ListBox that contains a set of DataItems. The DataTemplate for each item is an Expander. The header is text, the content of the Expander is a ListBox. The ListBox contains SubDataItems. The DataTemplate for each SubDataItem is an Expander. Here is a simplified XAML in which I reproduce the issue: <ListBox ItemsSource="{Binding Items}"> <ListBox.ItemTemplate> <DataTemplate> <Expander Header="{Binding Header}"> <ListBox ItemsSource="{Binding SubItems}"> <ListBox.ItemTemplate> <DataTemplate> <Expander Header="{Binding SubHeader}"> <Grid Height="40"> <TextBlock Text="{Binding SubText}" /> </Grid> </Expander> </DataTemplate> </ListBox.ItemTemplate> </ListBox> </Expander> </DataTemplate> </ListBox.ItemTemplate> </ListBox> There is a problem with how the layout is produced. If any Expander corresponding to the SubDataItem is expanded, the ListBoxItem containing this ListBox (the Expander.Content in the parent DataTemplate) correctly requests more space. So I can expand all SubDataItems and correctly see my data. However, when I collapse, the space I previously asked to expand, remains blank, instead of being reclaimed by the ListBoxItem. This is a problem because if I have say 10 SubDataItems and happen to expand all of them at the same time and then collapse, there is a significant amount of white space wasting my real estate. How can I force WPF to resize the ListBoxItem to the correct state?

  • C++ class derivation and superconstructor confusion

    - by LukeN
    Hey, in a tutorial C++ code, I found this particular piece of confusion: PlasmaTutorial1::PlasmaTutorial1(QObject *parent, const QVariantList &args) : Plasma::Applet(parent, args), // <- Okay, Plasma = namespace, Applet = class m_svg(this), // <- A member function of class "Applet"? m_icon("document") // <- ditto? { m_svg.setImagePath("widgets/background"); // this will get us the standard applet background, for free! setBackgroundHints(DefaultBackground); resize(200, 200); } I'm not new to object oriented programming, so class derivation and super-classes are nothing complicated, but this syntax here got me confused. The header file defines the class like this: class PlasmaTutorial1 : public Plasma::Applet { Similar to above, namespace Plasma and class Applet. But what's the public doing there? I fear that I already know the concept but don't grasp the C++ syntax/way of doing it. In this question I picked up that these are called "superconstructors", at least that's what stuck in my memory, but I don't get this to the full extend. If we glance back at the first snippet, we see Constructor::Class(...) : NS::SuperClass(...), all fine 'till here. But what are m_svg(this), m_icon("document") doing there? Is this some kind of method to make these particular functions known to the derivated class? Is this part of C++ basics or more immediate? While I'm not completly lost in C++, I feel much more at home in C :) Most of the OOP I have done so far was done in D, Ruby or Python. For example in D I would just define class MyClass : MySuperClass, override what I needed to and call the super class' constructor if I'd need to.

  • Process a set of files from a source directory to a destination directory in Python

    - by Spoike
    Being completely new in python I'm trying to run a command over a set of files in python. The command requires both source and destination file (I'm actually using imagemagick convert as in the example below). I can supply both source and destination directories, however I can't figure out how to easily retain the directory structure from the source to the destination directory. E.g. say the srcdir contains the following: srcdir/ file1 file3 dir1/ file1 file2 Then I want the program to create the following destination files on destdir: destdir/file1, destdir/file3, destdir/dir1/file1 and destdir/dir1/file2 So far this is what I came up with: import os from subprocess import call srcdir = os.curdir # just use the current directory destdir = 'path/to/destination' for root, dirs, files in os.walk(srcdir): for filename in files: sourceFile = os.path.join(root, filename) destFile = '???' cmd = "convert %s -resize 50%% %s" % (sourceFile, destFile) call(cmd, shell=True) The walk method doesn't directly provide what directory the file is under srcdir other than concatenating the root directory string with the file name. Is there some easy way to get the destination file, or do I have to do some string manipulation in order to do this?

  • Centered DIV w/ width dependant on text, buffered by two divs that should fill the containing DIV

    - by Andrew Thompson
    I have been wracking my brains on this seemingly small issue the whole day. My web dev friends are baffled and I could not find a suitable answer in my search of this site and others (though, I could have missed it somewhere along the way). Here's the problem: 3 DIVS within one fixed-width container DIV The center DIV has text that will be different on other sites The center DIV needs to be centered, and no larger than the text it contains. This is what I'd like to end up with The basic HTMl: <div id="container" > <div id="left" ></div> <div id="center" >Text inside center should resize this block</div> <div id="right" ></div> </div> Below, I removed most of the styles I have tried. This CSS currently centers the DIV (if I set it as an inline block), but I need the other divs to fill the left and right space remaining: #container { width:750px; text-align:center; } #left { background-color:#E85355; } #center { background-color:#CDD7D7; display:inline-block; } #right { background-color:#65A8A6; } I've tried floating, no-wrap, overflow, etc. Thanks a million to whomever can offer some help!

  • C++ std::vector memory/allocation

    - by aaa
    from a previous question about vector capacity, http://stackoverflow.com/questions/2663170/stdvector-capacity-after-copying, Mr. Bailey said: In current C++ you are guaranteed that no reallocation occurs after a call to reserve until an insertion would take the size beyond the value of the previous call to reserve. Before a call to reserve, or after a call to reserve when the size is between the value of the previous call to reserve and the capacity the implementation is allowed to reallocate early if it so chooses. So, if I understand correctly, in order to assure that no relocation happens until capacity is exceeded, I must do reserve twice? can you please clarify it? I am using vector as a memory stack like this: std::vector<double> memory; memory.reserve(size); memory.insert(memory.end(), matrix.data().begin(), matrix.data().end()); // smaller than size size_t offset = memory.size(); memory.resize(memory.capacity(), 0); I need to guarantee that relocation does not happen in the above. thank you. ps: I would also like to know if there is a better way to manage memory stack in similar manner other than vector

  • Image rotate opecv error

  • Is it possible to anti alias using Copy swap effect?

    - by Nor
    I'm developing an application in VB.Net using Managed DirectX that runs in windowed mode and renders onto a picture box that is smaller than the form. Whenever I resize the form, the back buffer is streched to fit the picture box. This is not what I would like. The backbuffer size is the same as screen size, however, I only want to render a part of the back buffer, whose size is controlled by the size of the picture box into which I'm rendering. Resetting the device with new presentation parameters is something I would like to avoid. I'm aware that I can use an overload of Device.Present if I set the swap effect to copy, but this doesn't allow me to use Multi Sample Anti Alias (which requires the Discard swap effect). It seems to me that the overload Device.Present is not usable with any other swap effect than copy, and throws an exception. An other alternative I considered is the PresentFlags.DeviceClip, however it seems that it works only for Windows XP. I'm using Windows 7 and it doesn't seem to be doing anything. So, is it even possible that I use anti-aliasing in this situation?

  • live image edit , and crop

    - by 422
    I was just thinking, which is always dangerous. We use Valums Image uploader. Aside from that, I am looking for an inline image editor, but with a difference. User uploads an image ( lets say 800 x 600 ) Our system wants to see the image ( 170 x 32 ) now I know we can use php to resize images. But I was thinking, does anyone know of a system, where we can display the image, and user can scale, and crop image ( with say a predefined overlay ) By that they scale down to nearest acceptable size, and then click crop tool, which shows a div overlay with say 70% transparency that they can drag over the image, and then click crop. So image is cropped to exact size we need, then can save . I am sure I have seen some jquery stuff done like this, just cannot for life of me find it. Essentialy, we would like to offer a simple client side image processor, thats lightweight, and then the ability to save what they did . Sorry no code to show, as its more of a request. Regards

  • Jquery - removing an image before the client browser attempts to download it

    - by ajbrun
    Hi there, I wonder if anyone could help me with a problem I've been having. I have a number of large images available, but due to space limitations, I can't create multiple copies of these at various sizes. I have used PHP GD functions to resize the images to the sizes I need and output them to the browser. This works, but obviously takes some processing time, which therefore impacts pages load times. I'm fine with this, but I only want to show the image once it's fully loaded, and have a loading gif in its place until that time. I'm using jquery to do this. The problem I'm having is making the page functional whether the client has javascript enabled or not. If JS is not enabled, I want standard img tags to be outputted, otherwise the images are removed and replaced with a loading gif until they have been fully loaded. The link below shows a simple non-javascript unfriendly example of a what I want to do (try turning JS off): http://jqueryfordesigners.com/demo/image-load-demo.php I've been testing the basics using the code below. The attr() function will be replaced with something like remove(). This is just a test to make something happen to the image before the browser tries to load it. $(document).ready(function() { $( "#Thumbnails .thumbnail img" ).attr('src', '#'); }); In IE, this works correctly - the image source is replaced with "#" BEFORE the client browser gets a chance to start downloading the image. In firefox however, it downloads the image, and THEN changes the source. It seems to me that firefox is loading the jquery onready event later than it should. As far as I know, this should be executed before the standard onload event and before anything has started loading. If it helps, I'm testing it with a good number of images on screen (81). Am I doing something wrong?
