  • Jquery image preview thumbnail doesn't seem to work....

    - by Pandiya Chendur
    I just tried the tooltip like this Easy image preview... But i cant get it to work.... I used this, <style> body { margin:0; padding:40px; background:#fff; font:80% Arial, Helvetica, sans-serif; color:#555; line-height:180%; } h1{ font-size:180%; font-weight:normal; color:#555; } h2{ clear:both; font-size:160%; font-weight:normal; color:#555; margin:0; padding:.5em 0; } a{ text-decoration:none; color:#f30; } p{ clear:both; margin:0; padding:.5em 0; } pre{ display:block; font:100% "Courier New", Courier, monospace; padding:10px; border:1px solid #bae2f0; background:#e3f4f9; margin:.5em 0; overflow:auto; width:800px; } img{border:none;} ul,li{ margin:0; padding:0; } li{ list-style:none; float:left; display:inline; margin-right:10px; } /* */ #preview{ position:absolute; border:1px solid #ccc; background:#333; padding:5px; display:none; color:#fff; } /* */ </style> <script type="text/javascript" src="jquery.js"></script> <ul> <li> <a href="Images/4.jpg" class="preview" title="Lake and a mountain"> <img src="Images/4s.jpg" alt="gallery thumbnail" /> </a> </li> </ul> and included style...

  • HowTo stick QDialog to Screen Borders like Skype do?

    - by mosg
    Hello. A long time ago I tried to find method how to stick QDialog window to screen borders for my small projects like Skype windows do it, but I failed. May be I was looking this code not in the right place, so now I'm looking the solution here, on stack! :) So, does any one have a deal with some kind of such code, links, samples? In my opinion, we have to reimplement QDialog moveEvent function, like below, but that code does not working: void CDialog::moveEvent(QMoveEvent * event) { QRect wndRect; int leftTaskbar = 0, rightTaskbar = 0, topTaskbar = 0, bottomTaskbar = 0; // int top = 0, left = 0, right = 0, bottom = 0; wndRect = this->frameGeometry(); // Screen resolution int screenWidth = QApplication::desktop()->width(); int screenHeight = QApplication::desktop()->height(); int wndWidth = wndRect.right() - wndRect.left(); int wndHeight = wndRect.bottom() - wndRect.top(); int posX = event->pos().x(); int posY = event->pos().y(); // Snap to screen border // Left border if (posX >= -m_nXOffset + leftTaskbar && posX <= leftTaskbar + m_nXOffset) { //left = leftTaskbar; this->move(leftTaskbar, posY); return; } // Top border if (posY >= -m_nYOffset && posY <= topTaskbar + m_nYOffset) { //top = topTaskbar; this->move(posX, topTaskbar); return; } // Right border if (posX + wndWidth <= screenWidth - rightTaskbar + m_nXOffset && posX + wndWidth >= screenWidth - rightTaskbar - m_nXOffset) { //right = screenWidth - rightTaskbar - wndWidth; this->move(screenWidth - rightTaskbar - wndWidth, posY); return; } // Bottom border if (posY + wndHeight <= screenHeight - bottomTaskbar + m_nYOffset && posY + wndHeight >= screenHeight - bottomTaskbar - m_nYOffset) { //bottom = screenHeight - bottomTaskbar - wndHeight; this->move(posX, screenHeight - bottomTaskbar - wndHeight); return; } QDialog::moveEvent(event); } Thanks.

  • Use fileupload as template field in a details view

    - by MyHeadHurts
    I have an admin page where a user will select a document path and add that path to a certain column of a database. I am using a fileupload on the page where they can find the document and copy the path and then paste it into the details view. However, I want to skip this step and I want them to select a document and automatically make the path show up in the details view. <asp:FileUpload ID="FileUpload1" runat="server" Visible="False" Width="384px" /><br /> <br /> <div> <asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional"> <ContentTemplate> <center> <asp:DetailsView ID="DetailsView1" runat="server" AllowPaging="True" AutoGenerateRows="False" DataKeyNames="ID" DataSourceID="SqlDataSource1" Height="128px" Width="544px" Visible="False" OnModeChanged="Button2_Click" CellPadding="4" ForeColor="#333333" GridLines="None" > <Fields> <asp:BoundField DataField="Order" HeaderText="Order" SortExpression="Order" /> <asp:BoundField DataField="Department" HeaderText="Department" SortExpression="Department"/> <asp:BoundField DataField="DOC_Type" HeaderText="DOC_Type" SortExpression="DOC_Type" /> <asp:BoundField DataField="Title" HeaderText="Title" SortExpression="Title" /> <asp:BoundField DataField="Revision" HeaderText="Revision" SortExpression="Revision" /> <asp:BoundField DataField="DOC" HeaderText="DOC" SortExpression="DOC" /> <asp:BoundField DataField="Active" HeaderText="Active" SortExpression="Active" /> <asp:BoundField DataField="Rev_Date" HeaderText="Rev_Date" SortExpression="Rev_Date" /> <asp:BoundField DataField="ID" HeaderText="ID" InsertVisible="False" ReadOnly="True" SortExpression="ID" Visible="False" /> <asp:CommandField ShowInsertButton="True" /> </Fields> <FooterStyle BackColor="#5D7B9D" BorderStyle="None" Font-Bold="True" ForeColor="White" /> <CommandRowStyle BackColor="#E2DED6" BorderStyle="None" Font-Bold="True" /> <RowStyle BackColor="#F7F6F3" BorderStyle="None" ForeColor="#333333" /> <FieldHeaderStyle BackColor="#E9ECF1" BorderStyle="None" Font-Bold="True" /> <EmptyDataRowStyle BorderStyle="None" /> <PagerStyle BackColor="#284775" BorderStyle="None" ForeColor="White" HorizontalAlign="Center" /> <HeaderStyle BackColor="#5D7B9D" BorderStyle="None" Font-Bold="True" ForeColor="White" /> <InsertRowStyle BorderStyle="None" /> <EditRowStyle BackColor="#999999" BorderStyle="None" /> <AlternatingRowStyle BackColor="White" BorderStyle="None" ForeColor="#284775" /> </asp:DetailsView> &nbsp; <br /> I need to get the fileupload1 into the DOC contenttemplate area so instead of showing an empty textbox it will show just a textbox it will show the fileupload

  • Managing multiple AJAX calls to PHP scripts

    - by relativelycoded
    I have a set of 5 HTML dropdowns that act as filters for narrowing results returned from a mySQL database. The three pertinent filters are for "Province", "Region", and "City" selection, respectively. I have three functions: findSchools(), which runs when any of the filters (marked with CSS class .filter) are changed, and fetches the results via AJAX from a PHP script. Once that is done, two other functions are called... changeRegionOptions(), which, upon changing the "Province" filter, and updates the available options using the same method as the first function, but posting to a different script. changeCityOptions(), which runs if the "Region" filter was changed, and updates options, again using the same method. The problem is that since I want these AJAX functions to run simultaneously, and they by nature run asynchronously, I've tried using $.when to control the execution of the functions, but it doesn't fix the problem. The functions run, but the Region and City filters return blank (no options); the FireBug report shows absolutely no output, even though the POST request went through. The posted parameter for filter_province gets sent normally, but the one for region gets cut off at the end -- it sends as filter_region=, with no value passed. So I'm presuming my logic is wrong somewhere. The code is below: // When any of the filters are changed, let's query the database... $("select.filter").change(function() { findSchools(); }); // First, we see if there are any results... function findSchools() { var sch_province = document.filterform.filter_province.value; var sch_region = document.filterform.filter_region.value; var sch_city = document.filterform.filter_city.value; var sch_cat = document.filterform.filter_category.value; var sch_type = document.filterform.filter_type.value; $.post("fetch_results.php", { filter_province : sch_province, filter_region : sch_region, filter_city : sch_city, filter_category : sch_cat, filter_type : sch_type }, function(data) { $("#results").html(""); $("#results").hide(); $("#results").html(data); $("#results").fadeIn(600); } ); // Once the results are fetched, we want to see if the filter they changed was the one for Province, and if so, update the Region and City options to match that selection... $("#filter_province").change(function() { $.when(findSchools()) .done(changeRegionOptions()); $.when(changeRegionOptions()) .done(changeCityOptions()); }); }; This is just one of the ways I've tried to solve it; I've tried using an IF statement, and tried calling the functions directly inside the general select.filter.change() function (after findSchools(); ), but they all return the same result. Any help with this would be great!

  • Why does this JSON.parse code not work?

    - by SuZi
    I am trying to pass json encoded values from a php script to a, GnuBookTest.js, javascript file that initiates a Bookreader object and use the values i have passed in via the variable i named "result". The php script is sending the values like: <div id="bookreader"> <div id="BookReader" style="left:10px; right:10px; top:30px; bottom:30px;">x</div> <script type="text/javascript">var result = {"istack":"zi94sm65\/BUCY\/BUCY200707170530PM","leafCount":"14","wArr":"[893,893,893,893,893,893,893,893,893,893,893,893,893,893]","hArr":"[1155,1155,1155,1155,1155,1155,1155,1155,1155,1155,1155,1155,1155,1155]","leafArr":"[0,1,2,3,4,5,6,7,8,9,10,11,12,13]","sd":"[\"RIGHT\",\"LEFT\",\"RIGHT\",\"LEFT\",\"RIGHT\",\"LEFT\",\"RIGHT\",\"LEFT\",\"RIGHT\",\"LEFT\",\"RIGHT\",\"LEFT\",\"RIGHT\",\"LEFT\"]"}</script> <script type="text/javascript" src="http://localhost:8080/application/js/GnuBookTest.js"></script> </div> </div> and in the GnuBookTest.js file i am trying to use the values like: br = new BookReader(); // Return the width of a given page. br.getPageWidth = function(index) { return this.pageW[index]; } // Return the height of a given page. br.getPageHeight = function(index) { return this.pageH[index]; } br.pageW = JSON.parse(result.wArr); br.pageH = JSON.parse(result.hArr); br.leafMap = JSON.parse(result.leafArr); //istack is an url fragment for location of image files var istack = result.istack; . . . Using JSON.parse as i have written it above loads the Bookreader and uses my values correctly in a few web-browsers: Firefox, IE8, and desktop-Safari; but does not work at all in mac-Chrome, mobile-Safari, plus older versions of IE. Mobile safari keeps giving me a reference error msg: can't find variable: JSON. The other browsers just do not load the Bookreader and show the "x" instead, like they did not get the values from the php script. Where is the problem?

  • Why is this OpenGL ES code slow on iPhone?

    - by f3r3nc
    I've slightly modified the iPhone SDK's GLSprite example while learning OpenGL ES and it turns out to be quite slow. Even in the simulator (on the hw worst) so I must be doing something wrong since it's only 400 textured triangles. const GLfloat spriteVertices[] = { 0.0f, 0.0f, 100.0f, 0.0f, 0.0f, 100.0f, 100.0f, 100.0f }; const GLshort spriteTexcoords[] = { 0,0, 1,0, 0,1, 1,1 }; - (void)setupView { glViewport(0, 0, backingWidth, backingHeight); glMatrixMode(GL_PROJECTION); glLoadIdentity(); glOrthof(0.0f, backingWidth, backingHeight,0.0f, -10.0f, 10.0f); glMatrixMode(GL_MODELVIEW); glClearColor(0.3f, 0.0f, 0.0f, 1.0f); glVertexPointer(2, GL_FLOAT, 0, spriteVertices); glEnableClientState(GL_VERTEX_ARRAY); glTexCoordPointer(2, GL_SHORT, 0, spriteTexcoords); glEnableClientState(GL_TEXTURE_COORD_ARRAY); // sprite data is preloaded. 512x512 rgba8888 glGenTextures(1, &spriteTexture); glBindTexture(GL_TEXTURE_2D, spriteTexture); glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, width, height, 0, GL_RGBA, GL_UNSIGNED_BYTE, spriteData); free(spriteData); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR); glEnable(GL_TEXTURE_2D); glBlendFunc(GL_ONE, GL_ONE_MINUS_SRC_ALPHA); glEnable(GL_BLEND); } - (void)drawView { .. glClear(GL_COLOR_BUFFER_BIT); glLoadIdentity(); glTranslatef(tx-100, ty-100,10); for (int i=0; i<200; i++) { glTranslatef(1, 1, 0); glDrawArrays(GL_TRIANGLE_STRIP, 0, 4); } .. } drawView is called every time the screen is touched or the finger on the screen is moved and tx,ty are set to the x,y coordinates where that touch happened. I've also tried using GLBuffer, when translation was pre-generated and there was only one DrawArray but gave the same performance (~4 FPS). ===EDIT=== Meanwhile I've modified this so that much smaller quads are used (sized: 34x20) and much less overlapping is done. There are ~400 quads-800 triangles spread on the whole screen. Texture size is 512x512 atlas and RGBA_8888 while the texture coordinates are in float. The code is very ugly in terms of API efficiency: there are two MatrixMode change along with two loads and two translation then a drawarrays for a triangle strip (quad). Now this produces ~45 FPS.

  • Placing a window near the system tray

    - by user227990
    I am writing a program that needs to set a window just above/below the traybar for gtk. I have tried using the 2 approaches that failed. One was using the gtk_status_icon_position_menu function and placing the window in the point where the user clicks (in the tray bar). The problem is that these solutions work in gnome(Linux) but not in Windows. In Linux they work because the window manager doesn't seem to allow placement of windows in the tray panel, honoring the closest possible. In Windows this doesn't happen and the window can go "out" of the screen which understandably is not desired. With this said i went out for a work around. My idea was to set the window in the location of mouse click and get the x and y coordinates of a normal window placement and with it's size check if it would be within the screen boundaries. If it was not make the correction. I have came up with the functions needed but for some reason the gdk_drawable_get_size(window-window ,&WindowWidth, &WindowHeight) and other similar functions only give the correct size value after the second run of the signal function. The result of the first run is just 1 to both size and width. (I have read the issue of X11 not giving correct results, but i think this is not it) event_button = (GdkEventButton *) event; if (event_button->button == 1) { if (active == 0) { gboolean dummy; gint WindowHeight, WindowWidth, WindowPosition[2]; GdkScreen *screen; gint ScreenHeight, ScreenWidth; dummy = FALSE; gtk_widget_show_all(window); gtk_window_present(GTK_WINDOW(window)); gtk_status_icon_position_menu(menu, &pos[X], &pos[Y], &dummy, statusicon); gtk_window_move(GTK_WINDOW(window), pos[X],pos[Y]); gdk_drawable_get_size(window->window ,&WindowWidth, &WindowHeight); screen = gtk_status_icon_get_screen(statusicon); ScreenWidth = gdk_screen_get_width(screen); ScreenHeight = gdk_screen_get_height(screen); g_print("Screen: %d, %d\nGeometry: %d, %d\n",ScreenWidth, ScreenHeight, WindowWidth, window->allocation.height); gtk_entry_set_text(GTK_ENTRY(entry),""); active = 1; return TRUE; } How can i do what i want in a portable way?

  • itextsharp PdfCopy and landscape pages

    - by Andreas Rehm
    I'm using itextsharp to join mutiple pdf documents and add a footer. My code works fine - except for landscape pages - it isn't detecting the page rotation - the footer is not centerd for landscape: public static int AddPagesFromStream(Document document, PdfCopy pdfCopy, Stream m, bool addFooter, int detailPages, string footer, int footerPageNumOffset, int numPages, string pageLangString, string printLangString) { CreateFont(); try { m.Seek(0, SeekOrigin.Begin); var reader = new PdfReader(m); // get page count var pdfPages = reader.NumberOfPages; var i = 0; // add pages while (i < pdfPages) { i++; // import page with pdfcopy var page = pdfCopy.GetImportedPage(reader, i); // get page center float posX; float posY; var rotation = page.BoundingBox.Rotation; if (rotation == 0 || rotation == 180) { posX = page.Width / 2; posY = 0; } else { posX = page.Height / 2; posY = 20f; } var ps = pdfCopy.CreatePageStamp(page); var cb = ps.GetOverContent(); // add footer cb.SetColorFill(BaseColor.WHITE); var gs1 = new PdfGState {FillOpacity = 0.8f}; cb.SetGState(gs1); cb.Rectangle(0, 0, document.PageSize.Width, 46f + posY); cb.Fill(); // Text cb.SetColorFill(BaseColor.BLACK); cb.SetFontAndSize(baseFont, 7); cb.BeginText(); // create text var pages = string.Format(pageLangString, i + footerPageNumOffset, numPages); cb.ShowTextAligned(PdfContentByte.ALIGN_CENTER, printLangString, posX, 40f + posY, 0f); cb.ShowTextAligned(PdfContentByte.ALIGN_CENTER, footer, posX, 28f + posY, 0f); cb.ShowTextAligned(PdfContentByte.ALIGN_CENTER, pages, posX, 20f + posY, 0f); cb.EndText(); ps.AlterContents(); // add page to new pdf pdfCopy.AddPage(page); } // close PdfReader reader.Close(); // return number of pages return i; } catch (Exception e) { Console.WriteLine(e); return 0; } } How do I detect the page rotation (e.g. landscape) format in this case? The given example works for PdfReader but not for PdfCopy. Edit: Why do I need PdfCopy? I tried copying a word pdf export. Some word hyperlinks will not work when you try to copy pages with PdfReader. Only PdfCopy transfers all needed page informations. Edit: (SOLVED) You need to use reader.GetPageRotation(i);

  • Issues loading Jquery (Galleria) script from inside an i-frame (beginner javascript?)

    - by 103188530284789248582
    Hello, first of all - I'm not entirely new to javascript, but am not fluent in it as I am with html and css, and am especially new to jQuery... so please excuse me if this questions seems easy or obvious, but after days of google I still have no solution to the problem... using jQuery 1.4.2.min, jQuery-ui-1.8.1 .... the site in question: http://homecapture.ca/sets/project_index.html The scenario: I have a tabbed menu generated from an unordered list, when a menu item is clicked it reveals an iframe which links to the page containing an image gallery. I am using jQuery UI tabs for the tabbed menu, and the galleries to which I'm linking are jQuery Galleria pages, automatically generated with Jalbum. The problem: The galleria plug-in only works normally from inside of the containing iframe in Chrome, has inconsistent behaviour in IE8 (seems to work in my local copy, but won't load properly online), and is not loaded properly in Firefox. Instead of displaying a thumbnail area and the first large image, the Galleria page shows the first thumbnail only, then when it is clicked the image it links to, but if you right-click and go Back, the iframe content shows up as a properly rendered Galleria page. Jalbum generates more script in the < head of the page in addition to linking to jquery and the galleria plug-in. All of it seems to be in charge of the gallery navigation , and I have relocated it to the < body of the page, in an effort to make it load after the parent page scripts, and together with the gallery content. At this point I am not sure what else I could do to solve the problem, without digging around in all or some of the library and pluging .js files (which I am not knowledgeable enough to do without some pointers). Has anyone dealt with a similar issue? I'm seeing some solutions for manipulating iframe content from a parent page with jQuery on here, is that what I should be researching instead? Thanks in advance for all the help! ps. I tried posting some code, but it seems I do not have enough 'reputation' for things to work right on here either :)

  • Monitoring DOM Changes in JQuery

    - by user363866
    Is there a way to detect when the disabled attribute of an input changes in JQuery. I want to toggle the style based on the value. I can copy/paste the same enable/disable code for each change event (as I did below) but I was looking for a more generic approach. Can I create a custom event that will monitor the disabled attribute of specified inputs? Example: <style type="text/css">.disabled{ background-color:#dcdcdc; }</style> <fieldset> <legend>Option 1</legend> <input type="radio" name="Group1" id="Radio1" value="Yes" />Yes <input type="radio" name="Group1" id="Radio2" value="No" checked="checked" />No <div id="Group1Fields" style="margin-left: 20px;"> Percentage 1: <input type="text" id="Percentage1" disabled="disabled" /><br /> Percentage 2: <input type="text" id="Percentage2" disabled="disabled" /><br /> </div> </fieldset> <fieldset> <legend>Option 2</legend> <input type="radio" name="Group2" id="Radio3" value="Yes" checked="checked" />Yes <input type="radio" name="Group2" id="Radio4" value="No" />No <div id="Group2Fields" style="margin-left: 20px;"> Percentage 1: <input type="text" id="Text1" /><br /> Percentage 2: <input type="text" id="Text2" /><br /> </div> </fieldset> <script type="text/javascript"> $(document).ready(function () { //apply disabled style to all disabled controls $("input:disabled").addClass("disabled"); $("input[name='Group1']").change(function () { var disabled = ($(this).val() == "No") ? "disabled" : ""; $("#Group1Fields input").attr("disabled", disabled); //apply disabled style to all disabled controls $("input:disabled").addClass("disabled"); //remove disabled style to all enabled controls $("input:not(:disabled)").removeClass("disabled"); }); $("input[name='Group2']").change(function () { var disabled = ($(this).val() == "No") ? "disabled" : ""; $("#Group2Fields input").attr("disabled", disabled); //apply disabled style to all disabled controls $("input:disabled").addClass("disabled"); //remove disabled style to all enabled controls $("input:not(:disabled)").removeClass("disabled"); }); }); </script>

  • Drawing text to <canvas> with @font-face does not work at the first time

    - by lemonedo
    Hi all, First try the test case please: http://lemon-factory.net/test/font-face-and-canvas.html I'm not good at English, so I made the test case to be self-explanatory. On the first click to the DRAW button, it will not draw text, or will draw with an incorrect typeface instead of the specified "PressStart", according to your browser. After then it works as expected. At the first time the text does not appear correctly in all browsers I've tested (Firefox, Google Chrome, Safari, Opera). Is it the standard behavior or something? Thank you. PS: Following is the code of the test case <!DOCTYPE html> <html> <head> <meta http-equiv=Content-Type content="text/html;charset=utf-8"> <title>@font-face and canvas</title> <style> @font-face { font-family: 'PressStart'; src: url('http://lemon-factory.net/css/fonts/prstart.ttf'); } canvas, pre { border: 1px solid #666; } pre { float: left; margin: .5em; padding: .5em; } </style> </head> <body> <div> <canvas id=canvas width=250 height=250> Your browser does not support the CANVAS element. Try the latest Firefox, Google Chrome, Safari or Opera. </canvas> <button>DRAW</button> </div> <pre id=style></pre> <pre id=script></pre> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script> <script> var canvas = document.getElementById('canvas') var ctx = canvas.getContext('2d') var x = 30 var y = 10 function draw() { ctx.font = '12px PressStart' ctx.fillStyle = '#000' ctx.fillText('Hello, world!', x, y += 20) ctx.fillRect(x - 20, y - 10, 10, 10) } $('button').click(draw) $('pre#style').text($('style').text()) $('pre#script').text($('script').text()) </script> </body> </html>

  • How do you set the ZIndex on a TabItem?

    - by CC Inc
    I am wanting my TabItems to be positioned in between a border to achieve a "binder" affect, like this: However, I cannot seem to achieve this affect using ZIndex with my borders and each TabItem item. Currently, I get this result: Using this code: <Border CornerRadius="40,40,0,0" Background="Orange" Margin="8,31,2,21" Grid.RowSpan="4" Panel.ZIndex="-3" ></Border> <Border CornerRadius="40,40,0,0" Background="Red" Margin="6,29,4,23" Grid.RowSpan="4" Panel.ZIndex="-1"></Border> <Border CornerRadius="40,40,0,0" Background="Yellow" Margin="3,26,7,26" Grid.RowSpan="4" Panel.ZIndex="1"></Border> <Border CornerRadius="40,40,0,0" Background="DarkRed" Margin="1,23,9,29" Grid.RowSpan="4" Panel.ZIndex="3"></Border> <Border CornerRadius="40,40,0,0" Background="OrangeRed" Margin="-2,19,12,33" Grid.RowSpan="4" Name="border1" Panel.ZIndex="5"></Border> <TabControl Name="tabControl1" TabStripPlacement="Bottom" Background="Transparent" Margin="-2,32,15,6" Grid.RowSpan="4" BorderThickness="0"> <TabItem Name="tabItem1" Margin="0,0,0,1" Panel.ZIndex="4"> <TabItem.Header> <TextBlock> Main</TextBlock> </TabItem.Header> </TabItem> <TabItem Name="tabItem2" Panel.ZIndex="5"> <TabItem.Header> <TextBlock Height="13" Width="91"> Internet Explorer</TextBlock> </TabItem.Header> </TabItem> <TabItem Name="tabItem3" Panel.ZIndex="0"> <TabItem.Header> <TextBlock> Firefox</TextBlock> </TabItem.Header> </TabItem> <TabItem Name="tabItem4" Panel.ZIndex="-2"> <TabItem.Header> <TextBlock> Chrome</TextBlock> </TabItem.Header> </TabItem> <TabItem Name="tabItem5" Panel.ZIndex="-4"> <TabItem.Header> <TextBlock> Opera</TextBlock> </TabItem.Header> </TabItem> </TabControl> However, this does not achieve the desired affect.

  • Escaping Code for Different Shells

    - by Jon Purdy
    Question: What characters do I need to escape in a user-entered string to securely pass it into shells on Windows and Unix? What shell differences and version differences should be taken into account? Can I use printf "%q" somehow, and is that reliable across shells? Backstory (a.k.a. Shameless Self-Promotion): I made a little DSL, the Vision Web Template Language, which allows the user to create templates for X(HT)ML documents and fragments, then automatically fill them in with content. It's designed to separate template logic from dynamic content generation, in the same way that CSS is used to separate markup from presentation. In order to generate dynamic content, a Vision script must defer to a program written in a language that can handle the generation logic, such as Perl or Python. (Aside: using PHP is also possible, but Vision is intended to solve some of the very problems that PHP perpetuates.) In order to do this, the script makes use of the @system directive, which executes a shell command and expands to its output. (Platform-specific generation can be handled using @unix or @windows, which only expand on the proper platform.) The problem is obvious, I should think: test.htm: <!-- ... --> <form action="login.vis" method="POST"> <input type="text" name="USERNAME"/> <input type="password" name="PASSWORD"/> </form> <!-- ... --> login.vis: #!/usr/bin/vision # Think USERNAME = ";rm -f;" @system './login.pl' { USERNAME; PASSWORD } One way to safeguard against this kind of attack is to set proper permissions on scripts and directories, but Web developers may not always set things up correctly, and the naive developer should get just as much security as the experienced one. The solution, logically, is to include a @quote directive that produces a properly escaped string for the current platform. @system './login.pl' { @quote : USERNAME; @quote : PASSWORD } But what should @quote actually do? It needs to be both cross-platform and secure, and I don't want to create terrible problems with a naive implementation. Any thoughts?

  • Do you know why introducing jquery ui autocomplete for my dropdown boxes is also changing my listbox

    - by oo
    I am trying to change my comboboxes to use autocomplete so i leverage the code listed here (which worked perfectly for my dropdowns) The issue is that i also on the same page have a listbox with the following code: <%= Html.ListBox("Cars", Model.BodyParts.Select( x => new SelectListItem { Text = x.Name, Value = x.Id, Selected = Model.CarsSelected.Any(y => y.Id == x.Id) } ))%> and it appears that the jquery ui code is changing this to a autocomplete dropdown as well (as opposed to keeping it as a multi select list box) any idea how to prevent this from happening? i literally am just using the exact code on this page <script type="text/javascript"> (function($) { $.widget("ui.combobox", { _create: function() { var self = this; var select = this.element.hide(); var input = $("<input>") .insertAfter(select) .autocomplete({ source: function(request, response) { var matcher = new RegExp(request.term, "i"); response(select.children("option").map(function() { var text = $(this).text(); if (!request.term || matcher.test(text)) return { id: $(this).val(), label: text.replace(new RegExp("(?![^&;]+;)(?!<[^<>]*)(" + request.term.replace(/([\^\$\(\)\[\]\{\}\*\.\+\?\|\\])/gi, "\\$1") + ")(?![^<>]*>)(?![^&;]+;)", "gi"), "<strong>$1</strong>"), value: text }; })); }, delay: 0, select: function(e, ui) { if (!ui.item) { // remove invalid value, as it didn't match anything $(this).val(""); return false; } $(this).focus(); select.val(ui.item.id); self._trigger("selected", null, { item: select.find("[value='" + ui.item.id + "']") }); }, minLength: 0 }) .addClass("ui-widget ui-widget-content ui-corner-left"); $("<button>&nbsp;</button>") .insertAfter(input) .button({ icons: { primary: "ui-icon-triangle-1-s" }, text: false }).removeClass("ui-corner-all") .addClass("ui-corner-right ui-button-icon") .position({ my: "left center", at: "right center", of: input, offset: "-1 0" }).css("top", "") .click(function() { // close if already visible if (input.autocomplete("widget").is(":visible")) { input.autocomplete("close"); return; } // pass empty string as value to search for, displaying all results input.autocomplete("search", ""); input.focus(); }); } }); })(jQuery); $(function() { $("select").combobox(); }); </script>

  • shuffling array javascript

    - by Dennis Callanan
    <!doctype html> <html lang="en"> <head> <meta charset="utf=8" /> <title>Blackjack</title> <link rel="stylesheet" href="blackjack.css" /> <script type="text/javascript"> var H2 = 2; var S2 = 2; var D2 = 2; var C2 = 2; var H3 = 3; var S3 = 3; var D3 = 3; var C3 = 3; var deck = new Array(H2, S2, D2, C2, H3, S3, D3, C3); var new_deck = new Array(); var r; document.write("deck = ") for (r =0; r<deck.length; r++){ document.write(deck[r]); } document.write("</br>") document.write("new deck = ") for (r=0; r<new_deck.length; r++){ document.write(new_deck[r]); } document.write("</br>") for (r=0;r<deck.length;r++){ var randomindex = Math.floor(Math.random()*deck.length); new_deck.push(randomindex) deck.pop(randomindex) } document.write("deck = ") for (r =0; r<deck.length; r++){ document.write(deck[r]); } document.write("</br>") document.write("new deck = ") for (r=0; r<new_deck.length; r++){ document.write(new_deck[r]); } document.write("</br>") </script> </head> <body> </body> </html> Obviously this isn't the full Blackjack game here. It's just a test to see if shuffling the array works by printing the contents of both decks (arrays) before and after the shuffle. I'm only using 8 cards at the moment, 4 2's and 4 3's. What I am getting from this is: deck = 22223333 new deck = deck = 2222 new deck = 7502 What I'm hoping to get is: deck = 22223333 new deck = deck = new deck = 23232323 (or any of the 8 numbers, generated randomly) So it should be shuffling those 8 cards, what am I doing wrong? I'm only new to javascript but I've used some python before. I've done something similar in python and worked perfectly, but I'm not sure what's wrong here. Thanks for any answers in advance!!

  • Android - Transforming widgets within transformed widgets and the resulting usability issues.

    - by Ben Rose
    Hello. I'm new to Android application development and I'm currently experimenting with various UI ideas. In the image below, you can see a vertically scrolling list of horizontally scrolling galleries (and also textviews as you can see). I'm also doing some matrix and camera transformations which I will come to in a minute. For the background of the list elements, I use green. Blue is the background of the galleries, and red is the background for the images. These are just for my benefit of learning. The galleries being used are extended classes where I overrode the drawChild method to perform a canvas scale operation in order for the image closest to the center (width) to be larger than the others. The list view going vertically, I overrode the drawChild method and used the camera rotations from lack of depth dimension in the canvas functionality. The items in the list are scaled down and rotated relative to their position's proximity to the center (height). I understood that scrolling and clicking would not necessarily follow along with the image transforms, but it appears as though the parent Gallery class's drawing is constrained to the original coordinates as well (see photo below). I would love to hear any insight any of you have regarding how I can change the coordinates of the galleries in what is rendered via gallery scroll and the touch responsiveness of said gallery. Images in the gallery are not same dimensions, so don't let that throw you in looking at the image below Thanks in advance! Ben link to image (could not embed) -- Update: I was using my test application UI and noticed that when I got the UI to the point of the linked image and then I touched the top portion of the next row in the list, the gallery updated to display the proper representation. So, I added a call to clearFocus() in the drawChild method and that resulted in more accurate drawing. It does seem a tad slower, and since I'm on the Incredible, I'm worried it is a bloated solution. In any event, I would still appreciate any thoughts you have regarding the best way to have the views display properly and how to translate the touch events in the gallery's new displayed area to its touchable coordinates so that scrolling on the actual images works when the gallery has moved. Thanks!
