How do I achieve that?

  • How to POST data to an HTTP page from an HTTPS page

    - by buster55
    I know this is a long shot, but I figured I'd ask the question anyway. I have an HTTPS page and am dynamically creating a form. I want to POST the form to an HTTP page. Is this possible without the browser popping up a warning? When I do this on IE8, I get the following message: Do you want to view only the webpage content that was delivered securely? Essentially, I'm asking about the inverse of question 1554237.

  • How to insert Google Adsense in a single post after the <!--More--> Tag

    - by Bob Cavezza
    I'm using wordpress, and I want to add the adsense javascript tags where the Read More tag goes in a blogpost. It's stored as <!--more--> in the database, but when you use the_content() this is automatically changed before I have the chance to use a str_replace() function. I'm looking to place an adsense tag for each post in the single.php page where the teaser ends. Has anyone been able to do this?

  • $_POST vs. $_SERVER['REQUEST_METHOD'] == 'POST'

    - by Scott
    Some guy called one of my Snipplr submissions "crap" because I used if ($_SERVER['REQUEST_METHOD'] == 'POST') instead of if ($_POST) Checking the request method seems more correct to me because that's what I really want to do. Is there some operational difference between the two or is this just a code clarity issue?

  • post__not_in only excluding first post in array

    - by fightstarr20
    I am using two query_posts loops to firstly display a set of posts with a custom field of '2012' and then the second loop to display everything else excluding the posts it returned in the first... <?php if( get_query_var('paged') < 2 ) { ?> <?php query_posts( array( 'post_type' => 'project', 'meta_key' => 'start_date_year', 'meta_value' => '2012' )); $ids = array(); ?> <?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?> <p>This is from Loop 1 - <?php the_title(); ?> - <?php the_id(); ?></p> <?php $ids[] = get_the_ID(); ?> <?php endwhile; endif; wp_reset_query(); ?> <?php } ?> <?php $paged = get_query_var( 'paged' ) ? get_query_var( 'paged' ) : 1; query_posts( array( 'post_type' => 'project', 'post__not_in' => $ids, 'orderby' => title, 'order' => ASC, 'paged' => $paged )); ?> <?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?> <p>This is from Loop 2 - <?php the_title(); ?> - <?php the_id(); ?></p> <?php endwhile; endif; wp_reset_query(); ?> <?php pagination(); ?> For some reason the 'post__not_in' = $ids is only excluding the first post ID in the array, I have print_r the array and it does contain all of the post IDs I want to exlcude. Anyone any ideas why only one ID is being excluded?

  • How to convert ISampleGrabber::BufferCB's buffer to a bitmap

    - by user2509919
    I am trying to use the ISampleGrabberCB::BufferCB to convert the current frame to bitmap using the following code: int ISampleGrabberCB.BufferCB(double sampleTime, IntPtr buffer, int bufferLength) { try { Form1 form1 = new Form1("", "", ""); if (pictureReady == null) { Debug.Assert(bufferLength == Math.Abs(pitch) * videoHeight, "Wrong Buffer Length"); } Debug.Assert(imageBuffer != IntPtr.Zero, "Remove Buffer"); Bitmap bitmapOfCurrentFrame = new Bitmap(width, height, capturePitch, PixelFormat.Format24bppRgb, buffer); MessageBox.Show("Works"); form1.changepicturebox3(bitmapOfCurrentFrame); pictureReady.Set(); } catch (Exception ex) { MessageBox.Show(ex.ToString()); } return 0; } However this does not seem to be working. Additionally it seems to call this function when i press a button which runs the following code: public IntPtr getFrame() { int hr; try { pictureReady.Reset(); } catch (Exception ex) { MessageBox.Show(ex.ToString()); } imageBuffer = Marshal.AllocCoTaskMem(Math.Abs(pitch) * videoHeight); try { gotFrame = true; if (videoControl != null) { hr = videoControl.SetMode(stillPin, VideoControlFlags.Trigger); DsError.ThrowExceptionForHR(hr); } if (!pictureReady.WaitOne(9000, false)) { throw new Exception("Timeout waiting to get picture"); } } catch { Marshal.FreeCoTaskMem(imageBuffer); imageBuffer = IntPtr.Zero; } return imageBuffer; } Once this code is ran I get a message box which shows 'Works' thus meaning my BufferCB must of been called however does not update my picture box with the current image. Is the BufferCB not called after every new frame? If so why do I not recieve the 'Works' message box? Finally is it possible to convert every new frame into a bitmap (this is used for later processing) using BufferCB and if so how? Edited code: int ISampleGrabberCB.BufferCB(double sampleTime, IntPtr buffer, int bufferLength) { Debug.Assert(bufferLength == Math.Abs(pitch) * videoHeight, "Wrong Buffer Length"); Debug.Assert(imageBuffer != IntPtr.Zero, "Remove Buffer"); CopyMemory(imageBuffer, buffer, bufferLength); Decode(buffer); return 0; } public Image Decode(IntPtr imageData) { var bitmap = new Bitmap(width, height, pitch, PixelFormat.Format24bppRgb, imageBuffer); bitmap.RotateFlip(RotateFlipType.RotateNoneFlipY); Form1 form1 = new Form1("", "", ""); form1.changepicturebox3(bitmap); bitmap.Save("C:\\Users\\...\\Desktop\\A2 Project\\barcode.jpg"); return bitmap; } Button code: public void getFrameFromWebcam() { if (iPtr != IntPtr.Zero) { Marshal.FreeCoTaskMem(iPtr); iPtr = IntPtr.Zero; } //Get Image iPtr = sampleGrabberCallBack.getFrame(); Bitmap bitmapOfFrame = new Bitmap(sampleGrabberCallBack.width, sampleGrabberCallBack.height, sampleGrabberCallBack.capturePitch, PixelFormat.Format24bppRgb, iPtr); bitmapOfFrame.RotateFlip(RotateFlipType.RotateNoneFlipY); barcodeReader(bitmapOfFrame); } public IntPtr getFrame() { int hr; try { pictureReady.Reset(); } catch (Exception ex) { MessageBox.Show(ex.ToString()); } imageBuffer = Marshal.AllocCoTaskMem(Math.Abs(pitch) * videoHeight); try { gotFrame = true; if (videoControl != null) { hr = videoControl.SetMode(stillPin, VideoControlFlags.Trigger); DsError.ThrowExceptionForHR(hr); } if (!pictureReady.WaitOne(9000, false)) { throw new Exception("Timeout waiting to get picture"); } } catch { Marshal.FreeCoTaskMem(imageBuffer); imageBuffer = IntPtr.Zero; } return imageBuffer; } I also still need to press the button to run the BufferCB Thanks for reading.

  • Flash (AS3) can't read response ...

    - by Quandary
    Question: I call an asp.net handler (ashx) like this from Flash, and onLoadSuccessful, I get the ashx response back. The problem now is whatever I do in onLoadSuccessful to get the responseStatus variable never gets me the variable (just an error message: property responseStatus for string not found), but the output of: trace("Response: " + evt.target.data); is Response: &responseStatus=ASP.NET+Fehler%3a+Die+Datei+%22C%3a%5cinetpub%5cwwwroot%5cRaumplaner_New%5cRaumplaner_New%5cabcdef.xml%22+konnte+nicht+gefunden+werden.& It used to work in ActionScript2...

  • Django Template tag, generating template block tag

    - by Issy
    Hi Guys, Currently a bit stuck, wondering if anyone can assist. I am using django-adminfiles. Which is a near little application. I want to use it to insert images into posts/articles/pages for a site i am building. How django-adminfiles works is it inserts a placeholder i.e <<< ImageFile and this gets rendered using a django template. It also has the feature of inserting custom options i.e (Insert Medium Image) , i figured i would used this to automatically resize images and include it in the post (similar to how WP does it). Django-adminfiles makes use of sorl.thumbnail app to generate thumbnails. So i have tried testing generating thumbnails: The current template that is used to render the inserted image is: {% spaceless %} <img src="{{ upload.upload.url }}" width="{{ upload.width }}" height="{{ upload.height }}" class="{{ options.class }}" class="{{ options.size }}" alt="{% if options.alt %}{{ options.alt }}{% else %}{{ upload.title }}{% endif %}" /> {% endspaceless %} I tried modifying this to: {% load thumbnail %} {% spaceless %} <img src="{% thumbnail upload.upload.url 200x50 %}" width="{{ upload.width }}" height="{{ upload.height }}" class="{{ options.class }}" class="{{ options.size }}" alt="{% if options.alt %}{{ options.alt }}{% else %}{{ upload.title }}{% endif %}" /> {% endspaceless %} I get the error: Exception Value: Caught an exception while rendering: Source file: '/media/uploads/DSC_0014.jpg' does not exist. I figured the thumbnail needs the absolute path so tried putting that in the template, and that works. i.e this works: {% thumbnail '/Users/me/media/uploads/DSC_0014.jpg' 200x50 %} So basically i need to generate the absolute path to the file give the relative path (to web root). You could do this by passing the MEDIA_ROOT setting to the template, but the reason i want to do a template tag is to programmatically set the image size.

  • Redirect uploaded files to another server, using nginx

    - by Serg ikS
    I am creating a web service of scheduled posts to some soc. network.Need help dealing with file uploads under high traffic. Process overview: User uploads files to SomeServer (not mine). SomeServer then responds with a JSON string. My web app should store that JSON response. Opt. 1 — Save, cURL POST, delete tmp The stupid way I made it work: User uploads files to MyWebApp; MyWebApp cURL's the file further to SomeServer, getting the response. Opt.2 — JS magic The smart way it could be perfect: User uploads the file directly to SomeServer, from within an iFrame; MyWebApp gets the response through JavaScript. But this is(?) impossible due to the 'Same Origin Policy', isn't it? Opt. 3 — nginx proxying? The better way for a production server: User uploads files to MyWebApp; nginx intercepts the file uploads and sends them directly to the SomeServer; JSON response is also intercepted by nginx and processed by MyWebApp. Does this make any sense, and what would be the nginx config for, say, /fileupload Location to proxy it to SomeServer ?

Kinda like when viewing the large picture from some galleries (sorry, no example link). Currently do I add a CSS class which has the image and other formating, but its not working for some reason. Results from the search do get inserted into the div.

  • How to retrieve checkboxlist values in the controller in asp.net mvc

    - by sukumar
    I am having a form in a view page that looks as below: <form runat="server" id="dcrsubmit"> <asp:CheckBoxList ID="CheckBoxList1" runat="server"> <asp:ListItem>test1</asp:ListItem> <asp:ListItem>test2</asp:ListItem> <asp:ListItem>test3</asp:ListItem> <asp:ListItem>test4</asp:ListItem> <asp:ListItem>test5</asp:ListItem> <asp:ListItem>test6</asp:ListItem> </asp:CheckBoxList> ....other controls </form> Now when the form is posted, I am trying to retrieve the values submitted in the controller as below: [AcceptVerbs(HttpVerbs.Post)] public ActionResult testmethod(FormCollection formValues) { string s = formvalues.get("CheckBoxList1"); . . /* other code */ . } The string value shows null when I submit the form by checking some checkboxes. Is this the way to retrieve the values or am I doing something wrong? And I cannot use html control because all other controls on the form are server controls and I am not sure if I can only make this control a html control. And I am not sure how can I bind the values to it?

  • Using PHP to get the source code of a URL I must be logged in to reach

    - by Maxwell
    I am trying to write a PHP script that will get the source code of a page in my Amazon account. However, to reach that page, I must be logged in. From what I understand, I should be able to accomplish this by posting the correct request headers, and then capturing the HTML response. Is that correct? If so, I'd really appreciate it if someone could explain to me how exactly I would do this. If it's not right, I'd love to hear the correct way of doing it! I've used Firebug to get the request and response headers I need. It's just a matter of what to do with them now. I read elsewhere on this site that you can't send a request with the PHP post method, and that perhaps using cURL is the way to go. I really know nothing about cURL, so the more info the better. Also, feel free to point me to some useful tutorials on this topic. Thanks! Max

  • Ajax request (from .NET) give me unexpected results

    - by ironnailpiercethesky
    I wanted to learn a little more about web and .NET so i decided to write a program to download binaries, webpages and does a little ajax. The first download site i tried was too easy. So i went against uploading.com. It seemed good, no captcha, some ajax use required, you cant guess all the data, it was perfect. After 2hours of messing around i got frustrated. For the life of me i could not get the ajax response to give me what i was expecting. I decided to use tamper data clear my cookies, click on the entry for the ajax request. Copy the Referer, cookies and postdata and came up with this code. It does not work! I am shocked that copying those fields did not work. I even tried setting the user agent (not in code linked) and it still did not work. Why isnt this POST on the ajax request not giving me the correct file? I notice the JsHttpRequest=12719132559480-xml changes based on time so if you want to run the code you should grab a new snapshot with tamperdata (or at least update that url). I dont see any extra headers in tamper data so does anyone know why i might not be getting the response expected? I know disabling cookies or javascript will make the link 'expired' automatically. I dont think javascript will matter because i got the data from tamperdata at the moment of request so what gives? What am i forgetting or what data am i not submitting properly?

  • overwrite parameters passed by querystring

    - by opensas
    I have the following problem I have a web framework built with classic asp that saves the page state in hidden textboxes, and then issues a submit to itself. Before submitting, we have a javascript functions that saves the action in a hidden "action" input, and then performs the submit. The page loads the state from those hidden texts, reads the action issued, reads extra parameters, like the id of the record to edit, and then builds the page accordingly. I'd like to make a url link to automatically start the page with "edit" action on a "x" id. So I was thinking about building the following url, for example http://myapp/user?action=edit&id=23 the problem is that when the page auto-submits, que url string keeps the parameters. I'd like to achieve the following: when the user clicks on http://myapp/user?action=edit&id=23 my page should receive the posted values action=edit and id=23 but the url should be just http://myapp/user and both parameters should be kept in the hidden texts... (I wonder if I make myself clear...) thanks a lot saludos sas ps: I have a couple of ideas about how to solve it, but I'll post them as answers...
