  • How do you set the initial value for a ManyToMany field in django?

    - by mlissner
    I am using a ModelForm to create a form, and I have gotten the initial values set for every field in the form except for the one that is a ManyToMany field. I understand that I need to give it a list, but I can't get it to work. My code right now is roughly: contacts = userProfile.contact.all() initial = {'contacts': contacts} But that doesn't work. Am I missing something here?

  • Getting a screenshot of a page using C# - Need help with code

    - by Ender
    I'm writing a specialised crawler and parser for internal use and I require the ability to take a screenshot of a web page in order to check what colours are being used throughout. The program will take in around ten web addresses and will save them as a bitmap image, from there I plan to use LockBits in order to create a list of the five most used colours within the image. To my knowledge it's the easiest way to get the colours used within a web page but if there is an easier way to do it please chime in with your suggestions. Anyway, I was going to use this program until I saw the price tag. I'm also fairly new to C#, having only used it for a few months. Can anyone provide me with a solution to my problem of taking a screenshot of a web page in order to extract the colour scheme? EDIT: Sorry for not getting back to this sooner, but I've been busy with some other things. Anyway, the code seems to work well, but the problem I am having right now is that I am running it within a form, and naturally with Application.Run() being called I cannot run two instances of the same form at once. It recommended Form.showDialog() but that broke everything. Can anyone give me a hand with this code? public static void buildScreenshotFromURL(string url) { int width = 800; int height = 600; using (WebBrowser browser = new WebBrowser()) { browser.Width = width; browser.Height = height; browser.ScrollBarsEnabled = true; // This will be called when the page finishes loading browser.DocumentCompleted += new System.Windows.Forms.WebBrowserDocumentCompletedEventHandler(OnDocumentCompleted); //browser.DocumentCompleted += OnDocumentCompleted; browser.Navigate(url); // This prevents the application from exiting until // Application.Exit is called // Application.Run() does not work as it cannot be called twice, recommended form.showDialog() // but still issues Application.Run(); } } public static void OnDocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e) { // Define size of thumbnail neded int thumbSize = 50; // Now that the page is loaded, save it to a bitmap WebBrowser browser = (WebBrowser)sender; // Code edited from example below to make smaller bitmap and save as PNG using (Graphics graphics = browser.CreateGraphics()) { using (Bitmap bitmap = new Bitmap(browser.Width, browser.Height, graphics)) { Rectangle bounds = new Rectangle(0, 0, bitmap.Width, bitmap.Height); browser.DrawToBitmap(bitmap, bounds); Bitmap thumbBitmap = new Bitmap(bitmap.GetThumbnailImage(thumbSize, thumbSize, thumbCall, IntPtr.Zero)); thumbBitmap.Save("screenshot.png", ImageFormat.Png); handleImage(thumbBitmap); } }

  • DOM Elements with same id and jQuery

    - by Steve
    Hi I have multiple elements with the same structure in my application. Second div element's id varies as per the comment id in the db which is unique. There are elements with the id 'vote_up' and 'vote_down'. This gets repeated for each comment.What happens is that, as I mentioned, there are multiple comments. I want to perform an Ajax request. First of this structure functions properly using ajax, but the rest does an http request. Btw I am developing a rails application and I am using jQuery. <div id="post_comment"> john<i> says </i> Comment<br/> <div id="comment_10_div"> **<form action="/comments/vote_up" id="vote_up" method="post">** <div style="margin:0;padding:0;display:inline"> <input name="authenticity_token" type="hidden" value="w873BgYHLxQmadUalzMRUC+1ql4AtP3U7f78dT8x9ho=" /> </div> <input id="Comment_place_id" name="Comment[post_id]" type="hidden" value="3" /> <input id="Comment_id" name="Comment[id]" type="hidden" value="10" /> <input id="Comment_user_id" name="Comment[user_id]" type="hidden" value="2" /> <input name="commit" type="submit" value="Vote up" /> </form> <label id="comment_10">10</label> **<form action="/comments/vote_down" id="vote_down" method="post">** <div style="margin:0;padding:0;display:inline"> <input name="authenticity_token" type="hidden" value="w873BgYHLxQmadUalzMRUC+1ql4AtP3U7f78dT8x9ho=" /> </div> <input id="Comment_place_id" name="Comment[place_id]" type="hidden" value="3" /> <input id="Comment_id" name="Comment[id]" type="hidden" value="10" /> <input id="Comment_user_id" name="Comment[user_id]" type="hidden" value="2" /> <input name="commit" type="submit" value="Vote Down" /> </form> </div> Can you please help me to solve this Thanks

  • Speeding Up Slow, CPU-Intensive Scrolling in WinForms

    - by S B
    How can I speed up the scrolling of UserControls in a WinForms app.? My main form has trouble scrolling quickly on slow machines--painting for each of the small scroll increments is CPU intensive. My form has roughly fifty UserControls (with multiple fields) positioned one below the other. I’ve tried intercepting OnScroll and UserPaint in order to eliminate some of the unnecessary re-paints for very small scroll events, but the underlying Paint gets called anyway. How can I streamline scrolling on slower machines?

  • Richfaces modal panel and a4j:keepAlive

    - by mykola
    Hello! I've got unexpected problems with richfaces (3.3.2) modal panel. When i try to open it, browser opens two panels instead of one: one is in the center, another is in the upper left corner. Besides, no fading happens. Also i have three modes: view, edit, new - and when i open my panel it should show either "Create new..." or "Edit..." in the header and actually it shows but not in the header as the latter isn't rendered at all though it should, because i set proper mode in action before opening this modal panel. Besides it works fine on all other pages i've made and there are tens of such pages in my application. I can't understand what's wrong here. The only way to fix it is to remove <a4j:keepAlive/> from the page that is very strange, imho. I'm not sure if code will be usefull here as it works fine everywhere in my application but this only case. So if you put it on your page it will probably work without problems. My only question is: are there any hidden or rare problems in interaction of these two elements (<rich:modalPanel> and <a4j:keepAlive>)? Or shall i spent another two or three days searching for some wrong comma, parenthesis or whatever in my code? :) For most curious. Panel itself: <!-- there's no outer form --> <rich:modalPanel id="panel" autosized="true" minWidth="300" minHeight="200"> <f:facet name="header"> <h:panelGroup id="panelHeader"> <h:outputText value="#{msg.new_smth}" rendered="#{MbSmth.newMode}"/> <h:outputText value="#{msg.edit_smth}" rendered="#{MbSmth.editMode}"/> </h:panelGroup> </f:facet> <h:panelGroup id="panelDiv"> <h:form > <!-- fields and buttons --> </h:form> </h:panelGroup> </rich:modalPanel> One of the buttons that open panel: <a4j:commandButton id="addBtn" reRender="panelHeader, panelDiv" value="#{form.add}" oncomplete="#{rich:component('panel')}.show()" action="#{MbSmth.add}" image="create.gif"/> Action invoked on button click: public void add() { curMode = NEW_MODE; // initial mode is VIEW_MODE newSmth = new Smth(); } Mode check: public boolean isNewMode() { return curMode == NEW_MODE; } public boolean isEditMode() { return curMode == EDIT_MODE; }

  • Display processing page then redirect when complete

    - by user285379
    I have a script that takes a while. I'd like to display a page during the processing of the script then redirect when the process is complete. E.g.: form.php - processing.php - display_result.php I would like that processing.php is displayed immediately after form is submitted showing (Processing your information, please wait...) Once processing is complete the page should be redirected to display_result.php Is there anyway to sort of flush the content to the browser before processing begins, then redirect when the process is complete?

    - by byanity
    I've added a EULA using VS2005's built in License Agreement UI form in a Setup Project. This form has a LicenseFile property that you set to an RTF file that displays the EULA. Assuming I have a number of translated RTFs, how can I make the EULA that is displayed point to the appropriate RTF localized to the user's Windows CurrentCulture settings? I've seen some articles on WiX but at this point I need to stick with our current installation setup. Thanks!

  • Thin-border on WPF window?

    I'd like to create a window, using WPF, that has a thin border all the way around the form - i.e. no space for the title bar with the icon/caption and min/max/close buttons. For example, the "extra" icons form of the new Windows 7 taskbar: How can I do this with WPF (I don't mind resorting to the Win32 API, if not supported natively by WPF)?

  • "Emulating" Application.Run using Application.DoEvents

    - by Luca
    I'm getting in trouble. I'm trying to emulate the call Application.Run using Application.DoEvents... this sounds bad, and then I accept also alternative solutions to my question... I have to handle a message pump like Application.Run does, but I need to execute code before and after the message handling. Here is the main significant snippet of code. // Create barrier (multiple kernels synchronization) sKernelBarrier = new KernelBarrier(sKernels.Count); foreach (RenderKernel k in sKernels) { // Create rendering contexts (one for each kernel) k.CreateRenderContext(); // Start render kernel kernels k.mThread = new Thread(RenderKernelMain); k.mThread.Start(k); } while (sKernelBarrier.KernelCount > 0) { // Wait untill all kernel loops has finished sKernelBarrier.WaitKernelBarrier(); // Do application events Application.DoEvents(); // Execute shared context services foreach (RenderKernelContextService s in sContextServices) s.Execute(sSharedContext); // Next kernel render loop sKernelBarrier.ReleaseKernelBarrier(); } This snippet of code is execute by the Main routine. Pratically I have a list of Kernel classes, which runs in separate threads, these threads handle a Form for rendering in OpenGL. I need to synchronize all the Kernel threads using a barrier, and this work perfectly. Of course, I need to handle Form messages in the main thread (Main routine), for every Form created, and indeed I call Application.DoEvents() to do the job. Now I have to modify the snippet above to have a common Form (simple dialog box) without consuming the 100% of CPU calling Application.DoEvents(), as Application.Run does. The goal should be to have the snippet above handle messages when arrives, and issue a rendering (releasing the barrier) only when necessary, without trying to get the maximum FPS; there should be the possibility to switch to a strict loop to render as much as possible. How could it be possible? Note: the snippet above must be executed in the Main routine, since the OpenGL context is created on the main thread. Moving the snippet in a separated thread and calling Application.Run is quite unstable and buggy...

  • Removing input background colour for Chrome autocomplete?

    - by DisgruntledGoat
    On a form I'm working on, Chrome is auto-filling the email and password fields. This is fine, however, Chrome changes the background colour to a pale yellow colour. The design I'm working on is using light text on a dark background, so this really messes up the look of the form - I have stark yellow boxes and near-invisible white text. Once the field is focused, the fields return to normal. Is it possible to stop Chrome changing the colour of these fields?
