  • How to make overflow: hidden really hide content?

    - by tambourine
    Please, look at this example. I intend making horizontal layout with pure html/css, don't bother of old browsers. I made it with display: table technique. But displaying main text containers (light-yellow) became a problem. Each of this has overflow: hidden to prevent vertical scroll. Later, I intend adding some shadow effect at the bottom. Now, I want to make in, for example, 80% height with 10% margin top and bottom. But what I get is container with larger text stretching all parents container (light-green), so 80% of it became too much. Is there any way to avoid it without javascript? Maybe I can get text container any height, but with some margin at the bottom. I will appreciate any solution.

  • read files from directory and filter files from Java

    - by Adnan
    The following codes goes through all directories and sub-directories and outputs just .java files; import java.io.File; public class DirectoryReader { private static String extension = "none"; private static String fileName; public static void main(String[] args ){ String dir = "C:/tmp"; File aFile = new File(dir); ReadDirectory(aFile); } private static void ReadDirectory(File aFile) { File[] listOfFiles = aFile.listFiles(); if (aFile.isDirectory()) { listOfFiles = aFile.listFiles(); if(listOfFiles!=null) { for(int i=0; i < listOfFiles.length; i++ ) { if (listOfFiles[i].isFile()) { fileName = listOfFiles[i].toString(); int dotPos = fileName.lastIndexOf("."); if (dotPos > 0) { extension = fileName.substring(dotPos); } if (extension.equals(".java")) { System.out.println("FILE:" + listOfFiles[i] ); } } if(listOfFiles[i].isDirectory()) { ReadDirectory(listOfFiles[i]); } } } } } } Is this efficient? What could be done to increase the speed? All ideas are welcome.

  • Parsing XML using xml.etree.cElementTree

    - by Andre
    I have the following XML in a string named 'xml': <?xml version="1.0" encoding="ISO-8859-1"?> <Book> <Page> <Text>Blah</Text> </Page> </Book> I'm trying to get the value Blah out of it but I'm having trouble with xml.etree.cElementTree. I've tried the find() and findtext() methods but nothing. Eventually I did this: import xml.etree.cElementTree as ET ... root = ET.fromstring(xml) element = root.getchildren()[0].getchildren()[0] Element now equals the element, which is what I want (for this solution anyway), but how do I get the inner text from it? element.text does not work. Any ideas? PS: I am using Python 2.5 atm. As an extra question: what is a better way to parse xml strings in python?

  • Kohanav3 ORM: calling where->find_all twice

    - by David Lawson
    When I do something like the following: $site = ORM::factory('site')->where('name', '=', 'Test Site')->find(); $users = $site->users; $deletedusers = $users->where('deleted', '=', '1')->find_all(); $nondeletedusers = $users->where('deleted', '=', '0')->find_all(); The contents of $deletedusers is correct, but the $nondeletedusers contains every non-deleted user, not just the ones in the loaded $site. What am I doing wrong?

  • Checking For Empty Enumerations

    While spelunking in some code recently I saw a method that looked something like this: public void Foo<T>(IEnumerable<T> items) { if(items == null || items.Count() == 0) { // Warn about emptiness } } This method accepts a generic enumeration and then proceeds to check if the enumeration is null or empty. Do you see the potential problem with this code? Ill give you a hint, its this line: items.Count() == 0 Whats the problem? Well that line right there has the potential...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • Using ReportViewer 9 control in VS 2010

    - by Fermin
    Hi, I am writing an ASP.NET app that uses a SQL Server 2005 with SSRS setup. I want to use the ReportViewer control but I get an error when using ReportViewer 10 because it needs SSRS 2008. How can I use ReportViewer 9 within my application. I've added a reference to the Microsoft.ReportViewer.WebForms.dll version 9 and removed the reference to version 10. My markup is as follows: <%@ Register Assembly="Microsoft.ReportViewer.WebForms, Version=9.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" Namespace="Microsoft.Reporting.WebForms" TagPrefix="rsweb" %> <!-- standard markup --> <rsweb:ReportViewer ID="ReportViewer1" runat="server"></rsweb:ReportViewer> but when I try to run this I get the following error: CS0433: The type 'Microsoft.Reporting.WebForms.ReportViewer' exists in both 'c:\WINDOWS\assembly\GAC_MSIL\Microsoft.ReportViewer.WebForms\10.0.0.0__b03f5f7f11d50a3a\Microsoft.ReportViewer.WebForms.dll' and 'c:\WINDOWS\assembly\GAC_MSIL\Microsoft.ReportViewer.WebForms\9.0.0.0__b03f5f7f11d50a3a\Microsoft.ReportViewer.WebForms.dll' What have I missed!? Update: When trying to use the ReportViewer 10 I get the following error: "Remote report processing requires Microsoft SQL Server 2008 Reporting Services or later."

  • Confirm box always displays first (javascript, jQuery, .Net)

    - by Jan-Frederik Carl
    Hello, I have a jQuery-Script to accomplish the following tasks: if a gridview in my form contains a row with a certain id, it has to be marked red. a confirm dialogue has to pop up to ask the user if he wants to do this or that. I built this code: if (response == "EntryInList") { $('#entryListContainer div table tbody tr').each(function() { if ($(this).attr('id') == 'entry_' + $('#<%= txtProductNumber.ClientID %>').val()) { $(this).css("color", "red"); } } ); if (!confirm("Entry already exists. Really overwrite?")) { jQuery('#<%= txtProductNumber.ClientID %>').val(''); jQuery('#<%= txtCount.ClientID %>').val(''); jQuery('#<%= txtProductNumber.ClientID %>').focus(); return false; } } As a result, the confirm box pops up first, without the row being turned red. Only after using the box, it becomes red. How would I get the row to be turned red at once? Another of my problems is that the confirm box denies my page to be scrolled down. But I would like to do this if the gridview is longer than the entire page.

  • django username in url, instead of id

    - by dana
    Hello, in a mini virtual community, i have a profile_view function, so that i can view the profile of any registered user. The profile view function has as a parameter the id of the user wich the profile belongs to, so that when i want to access the profile of user 2 for example, i call it like that: http://127.0.0.1:8000/accounts/profile_view/2/ My problem is that i would like to have the username in the url, and NOT the id. I try to modify my code as follows, but it doesn't work still. Here is my code: view: def profile_view(request, user): u = User.objects.get(pk=user) up = UserProfile.objects.get(created_by = u) cv = UserProfile.objects.filter(created_by = User.objects.get(pk=user)) blog = New.objects.filter(created_by = u) replies = Reply.objects.filter(reply_to = blog) vote = Vote.objects.filter(voted=blog) following = Relations.objects.filter(initiated_by = u) follower = Relations.objects.filter(follow = u) return render_to_response('profile/publicProfile.html', { 'vote': vote, 'u':u, 'up':up, 'cv': cv, 'ing': following.order_by('-date_initiated'), 'er': follower.order_by('-date_follow'), 'list':blog.order_by('-date'), 'replies':replies }, context_instance=RequestContext(request)) and my url: urlpatterns = patterns('', url(r'^profile_view/(?P<user>\d+)/$', profile_view, name='profile_view'), thanks in advance!

  • Jquery JQGrid - How to set alignment of grid header cells?

    - by JK
    Is it possible to align grid column headers in jqgrid? eg align left right or center? In the jqrid documents http://www.trirand.com/jqgridwiki/doku.php?id=wiki:colmodel_options it says: align: Defines the alignment of the cell in the Body layer, not in header cell. Possible values: left, center, right. Note that it says "not in the header cell". How can I do this for the header cell (grid title cell)? The documentation fails to mention this little detail....

  • Can expiration policies be configured in entlib caching application block?

    - by stesoc
    Hi, Is there a way to tell a CacheManager that every item added will have the same expiration policy? For example in: <cachingConfiguration defaultCacheManager="DefaultCacheManager"> <cacheManagers> <add name="TestCM" expirationPollFrequencyInSeconds="60" maximumElementsInCacheBeforeScavenging="1000" numberToRemoveWhenScavenging="10" backingStoreName="Null Storage" type="Microsoft.Practices.EnterpriseLibrary.Caching.CacheManager, Microsoft.Practices.EnterpriseLibrary.Caching, Version=4.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/> I expected to have some attribute like expirationPolicy="AbsoluteTime" or "SlidingTime" and a expirationValue="..." for specifying the timespan to use. Thanks, s.

  • JTable - Getting a cell into Edit mode on pressing Tab

    - by Luhar
    This is possibly has a trivial solution, but I am at the end of my tether so I hope somebody can help out. I use a JTable which has a custom renderer and a custom editor for a set of columns. The renderer uses a JLabel component and the editor uses a JSpinner component. Our users want to be able to enter values in a column, and then press TAB or ENTER to move to the next editable cell in the table. If I understand correctly, this is the default behaviour for a JTable. However, this doesn't seem to work correctly for me. Until the user clicks on the cell, only the JLabel is displayed. The JSpinner (i.e. CellEditor) is only displayed when a user double clicks on the cell. So, it looks like the cell is going into "edit" mode only on MouseEvents, but not when it has focus. How do I get the cell to go into edit mode as soon as it has focus?

  • Show EPS file in ABCpdf with standards modes set to IE8

    - by runrunraygun
    <meta http-equiv="X-UA-Compatible" content="IE=8"> or <meta http-equiv="X-UA-Compatible" content="IE=EmulateIE8"> With this set my EPS files are not rendered in ABCpdf, but set to EmulateIE7 and they work fine. I know EPS aren't a standard web format but they are embedded into a PDF using a bit of ABCpdf magic. Because IE8 isn't even trying to show them they are not appearing on the PDF as they previously were. <embed style="abcpdf-tag-visible: true;width:40px;height:40px;" id="C:\myfile.eps" src="myfile.eps">

  • How to call operator<< on "this" in a descendant of std::stringstream?

    - by romkyns
    class mystream : public std::stringstream { public: void write_something() { this << "something"; } }; This results in the following two compile errors on VC++10: error C2297: '<<' : illegal, right operand has type 'const char [10]' error C2296: '<<' : illegal, left operand has type 'mystream *const ' Judging from the second one, this is because what this points at can't be changed, but the << operator does (or at least is declared as if it does). Correct? Is there some other way I can still use the << and >> operators on this?
