  • Help with Role Based Security.

    - by Bill K
    Hello, I'm trying to understand role based security and I have the following method: [PrincipalPermission(SecurityAction.Demand, Role = "Administrators")] static void Test() { //administratos only can call this code } What I wanna do is that only users that are members of the Windows Administrators group can call this code, however, if I do the following, it works: GenericIdentity genericIdentity = new GenericIdentity("test", "test"); GenericPrincipal genericPrincipal = new GenericPrincipal(genericIdentity, new string[] { "Administrators" }); AppDomain.CurrentDomain.SetThreadPrincipal(genericPrincipal); Test(); So, how can I make it work only if the user is in the Administrators windows group? thanks!

  • .net Studio Local Database

    - by testerwpf
    Hello everyone, i am designing a local database in .net with wpf as gui. I have added a new database, and added a new table. Through the TableAdapter i generated 2 statements ( 1 statement is a select stmt and 1 is a insert) , i insert name and firstname (id is auto generated). It works fine, i can display the table in a datagrid (wpf toolkit) and also add new items (name,firstname), when i close and start the application everything is fine (data in table is stored) BUT when i try to preview data in my database dataset (where my Adapters exist) , no data is displayed and then the table gets deleted.. why? public partial class MainWindow : Window { public MainWindow() { this.InitializeComponent(); PlayerTableAdapter objPlayerTableAdapter = new PlayerTableAdapter(); objDataGridResults.ItemsSource = objPlayerTableAdapter.GetDataAllPlayer(); } //Button Event onClick private void m_voidAddPlayer(object sender, System.Windows.RoutedEventArgs e) { PlayerTableAdapter objPlayerTableAdapter = new PlayerTableAdapter(); objPlayerTableAdapter.InsertQueryPlayer(objTextBoxPlayerName.Text.ToString(), objTextBoxPlayerFirstName.Text.ToString()); objDataGridResults.ItemsSource = objPlayerTableAdapter.GetDataAllPlayer(); } }

  • Default taglibs used within included JSPs for editing

    - by lostiniceland
    Hello everyone Within Eclipse's jsp-editor, as you all know, I get code-assistance for external taglibs once I defined them. In the project I am working on now a lot of jsps are just included and have no taglib definition in the top which gives me a lot of editor warnings. In the deployment this doesnt matter because the taglibs are defined in the head-jsp. Is there a way that I can define default taglibs within a project so the eclipse editor will give me code-assist even though I dont include the taglib in each file again?

  • GPU YUV to RGB. Worth the effort?

    - by Jaime Pardos
    Hello, I have to convert several full PAL videos (720x576@25) from YUV 4:2:2 to RGB, in real time, and probably a custom resize for each. I have thought of using the GPU, as I have seen some example that does just this (except that it's 4:4:4 so the bpp is the same in source and destiny)-- http://www.fourcc.org/source/YUV420P-OpenGL-GLSLang.c However, I don't have any experience with using GPU's and I'm not sure of what can be done. The example, as I understand it, just converts the video frame to YUV and displays it in the screen. Is it possible to get the processed frame instead? Would it be worth the effort to send it to the GPU, get it transformed, and sending it again to main memory, or would it kill performance? Being a bit platform-specific, assuming I work on windows, is it possible to get an OpenGL or DirectDraw surface from a window so the GPU can draw directly to it?

  • How to generate pdf files _with_ utf-8 multibyte characters using Zend Framework

    - by Sejanus
    Hello, I've got a "little" problem with Zend Framework Zend_Pdf class. Multibyte characters are stripped from generated pdf files. E.g. when I write aabccdee it becomes abcd with lithuanian letters stripped. I'm not sure if it's particularly Zend_Pdf problem or php in general. Source text is encoded in utf-8, as well as the php source file which does the job. Thank you in advance for your help ;) P.S. I run Zend Framework v. 1.6 and I use FONT_TIMES_BOLD font. FONT_TIMES_ROMAN does work

  • Call click event on last clicked row in YUI datatable

    - by Javi
    Hello, I have a YUI datatable and I have a function which is invoked when I click on a row: ... YAHOO.keycoes.myDatatable = myDatatable; ... myDatatable.subscribe("rowClickEvent", oneventclickrow); var oneventclickrow = function( args ) { ... } I'd like to invoke the function subscribed to rowClickEvent on the row which is currently highlighted in the datatable (the row which was clicked for the last time). I've tried to do something like this: YAHOO.keycoes.myDatatable.getSelectedRows()[0].rowClickEvent() but getSelectedRows() doesn't return any row. How can I get the highlighted row in the datatable and then call the function associated with rowClickEvent? Thanks

  • Checking if file exist with RewriteCond in a chained RewriteRule

    - by gelilloabad
    Hello, I hope you could help me here. I have a RewriteRule which gives you a crossdomain.xml file depending on the domain name. I have it in a way that ignores the ".dev." string in the middle, example: Request: http://site1.dev.mydomain.com/crossdomain.xml Returns file: /etc/httpd/conf/crossdomain/site.mydomain.com.xml RewriteCond %{HTTP_HOST} "^(.*)\.dev\.(.*)" RewriteCond %{REQUEST_URI} "/crossdomain.xml" enter code hereRewriteRule ^(.+) %{HTTP_HOST}$1 [C] RewriteRule ^(.*)\.dev\.([^/]*)/crossdomain.xml /etc/httpd/conf/crossdomain/$1.$2.xml [L] Question: How do I check if the file exists? I tried adding this on top but it doesn't work: RewriteCond /etc/httpd/conf/crossdomain/$1.$2.xml -f I guess because it is a chained rule, no idea. Please help.

  • how to make tooltip move along with mouse?

    - by George2
    Hello everyone, I am using Silverlight 3 + VSTS 2008. I have a image (Multiscale image control) and I place tooltip on this image. The function of Tooltip works fine. Since the image is big (about 500 * 500 size), and since end user could move mouse on the picture, and I want to display tooltip position along with the mouse (i.e. when mouse moves, I want to tooltip move along with the mouse). Currently, the tooltip displays at a fixed position. Here is my current XAML code, any ideas how to solve this issue? <MultiScaleImage x:Name="msi" Height="500" Width="500"> <ToolTipService.ToolTip> <ToolTip Content="Here is a tool tip" Name="DeepZoomToolTip"></ToolTip> </ToolTipService.ToolTip> </MultiScaleImage> thanks in advance, George

  • Do Blob properties on entities affect query performance?

    - by Jaroslav Záruba
    Hello I'm trying to make my mind on whether to store a binary representation of an entity as its Blob property, or whether I better keep the blobs in some separate 'wrapping' class. Possible impact on memory heap and/or a query execution time are my concerns in the first case, complexity votes against the other one. I know Blobs are not indexed, i.e. index size is not what I'm worrying about. Also I assume for blobs Datastore puts defaultFetchGroup to false, but does it mean that blobs don't make a difference in queries? Regards J. Záruba

  • What happens to my web application if Javascript is disabled?

    - by Richard77
    Hello, I'm learning JQuery and am about to write some pages using intensively that library. I just learned that some user disable javascript on their browser (I didn't even know that was possible and/or necessary). Now, here's my question: What happens to my web application if a user disable Javascript? For instance, I'd like to display some screens using Ajax and commands such as 'InsertBefore' to bring in live a DIV that will display the result. So, if Javascript is disabled, I wonder what going to happen to all this work that relies on Javascript? I'm kind of lost. Thanks for helping

  • Session persistence problem

    - by YsoL8
    Hello I'm having a problem with getting sessions to persist, and having no luck searching, I need to ask. I can access the contents of my session as expected when first set, but as soon as the page refreshes I lose everything and I don't see why. session_start() is set and I'm not unseting or destroying anything. I looked at PHP Info under sessions and everything looks ok (but my understanding of sessions is limited). I'm running MAMP on OS 10.5, and the last time I used sessions they worked.

  • How do I use CSS to add a non-rectangular border around an image?

    - by KPL
    Hello people, I have three images, and they are not square or rectangular in shape. They are just like face of anyone. So, basically, my images are in the size 196x196 or anything like that, but complete square or rectangle with the face in the middle and transperant background in the rest of the portion. Now, I want to remove the transperant background too and just keep the faces. Don't know if this is possible and mind you, this isn't a programming question. EDIT (from comments): How do I put a border around the shape of the image, not a rectangular one around the boundary, using CSS.

  • Resizing a UIButton programmatically by maintaining a margin

    - by Oscar Del Ben
    Hello, I'm adding a UIButton to a tableView footer programmatically. This button has a left and right margin that is equal to the tableView margin: UIButton *deleteButton = [UIButton buttonWithType:UIButtonTypeRoundedRect]; deleteButton.frame = CGRectMake(10, 60, 300, 34); deleteButton.autoresizingMask = UIViewAutoresizingFlexibleWidth I'm adding autoresizingMask because I want to support rotation. However, it does not work as I want, as the button stretches all the way down to the right, as shown by the image below. Any idea how to fix it? If I remove the autosizing property then the margin is correct.

  • Wrapping \NewEnviron into \newenvironment fails

    - by o_O Tync
    Hello! I am trying to wrap an environment created with \NewEnviron (package 'environ') into an old good \newenvironment: \NewEnviron{test}{aaa(\BODY)bbb} \newenvironment{wrapper}{\begin{test}}{\end{test}} \begin{wrapper} debug me \end{wrapper} However, this gives me a strange error: LaTeX Error: \begin{test} on input line 15 ended by \end{wrapper}. LaTeX Error: \begin{wrapper} on input line 15 ended by \end{document}. If I replace \NewEnviron{test}{aaa(\BODY)bbb} with \newenvironment{test}{aaa(}{)bbb} — everything works as expected! It seems like \NewEnviron fails to find its end for some reason. I'm trying to do some magic with 'floatfig' wrapped into a \colorbox so I need a way to convert \colorbox to an environment and wrap it into another one. I can define a new command but it's not a very good idea. Thanks in advance!

  • Bypass django form validation on new form instance

    - by Thomas Schultz
    Hello! I have a situation where we are trying to autofill some form data on the second page of a signup and I was wondering if there's a way to bypass the entire form validation when we pass in only a couple of fields? so we have something like form = NewForm(request.POST) Where request.POST only contains some of the fields in NewForm(). So the page loads and there is feedback about how some fields are not filled in yet. This all happens from the GET request of the second page. Is there a way to do something like... form = NewForm(request.POST, validate=False)

  • uniform generation of 3D points on cylinder/cone

    - by Myx
    Hello: I wish to randomly and uniformly generate points on a cylinder and a cone (separately). The cylinder is defined by its center, its radius and height. Same specifications for the cone. I am able to get the bounding box for each shape so I was thinking of generating points within the bounding box. However, I'm not sure how to project them onto the cylinder/cone or if this is the best idea. Any suggestions? Thanks.
