  • c# video equivalent to image.fromstream? Or changing the scope of the following script to allow vide

    - by Daniel
    The following is a part of an upload class in a c# script. I'm a php programmer, I've never messed with c# much but I'm trying to learn. This upload script will not handle anything except images, I need to adapt this class to handle other types of media also, or rewrite it all together. If I'm correct, I realize that using (Image image = Image.FromStream(file.InputStream)) basically says that the scope of the following is Image, only an image can be used or the object is discarded? And also that the variable image is being created from an Image from the file stream, which I understand to be, like... the $_FILES array in php? I dunno, I don't really care about making thumbnails right now either way, so if this can be taken out and still process the upload I'm totally cool with that, I just haven't had any luck getting this thing to take anything but images, even when commenting out that whole part of the class... protected void Page_Load(object sender, EventArgs e) { string dir = Path.Combine(Request.PhysicalApplicationPath, "files"); if (Request.Files.Count == 0) { // No files were posted Response.StatusCode = 500; } else { try { // Only one file at a time is posted HttpPostedFile file = Request.Files[0]; // Size limit 100MB if (file.ContentLength > 102400000) { // File too large Response.StatusCode = 500; } else { string id = Request.QueryString["userId"]; string[] folders = userDir(id); foreach (string folder in folders) { dir = Path.Combine(dir, folder); if (!Directory.Exists(dir)) Directory.CreateDirectory(dir); } string path = Path.Combine(dir, String.Concat(Request.QueryString["batchId"], "_", file.FileName)); file.SaveAs(path); // Create thumbnail int dot = path.LastIndexOf('.'); string thumbpath = String.Concat(path.Substring(0, dot), "_thumb", path.Substring(dot)); using (Image image = Image.FromStream(file.InputStream)) { // Find the ratio that will create maximum height or width of 100px. double ratio = Math.Max(image.Width / 100.0, image.Height / 100.0); using (Image thumb = new Bitmap(image, new Size((int)Math.Round(image.Width / ratio), (int)Math.Round(image.Height / ratio)))) { using (Graphics graphic = Graphics.FromImage(thumb)) { // Make sure thumbnail is not crappy graphic.SmoothingMode = SmoothingMode.HighQuality; graphic.InterpolationMode = InterpolationMode.High; graphic.CompositingQuality = CompositingQuality.HighQuality; // JPEG ImageCodecInfo codec = ImageCodecInfo.GetImageEncoders()[1]; // 90% quality EncoderParameters encode = new EncoderParameters(1); encode.Param[0] = new EncoderParameter(Encoder.Quality, 90L); // Resize graphic.DrawImage(image, new Rectangle(0, 0, thumb.Width, thumb.Height)); // Save thumb.Save(thumbpath, codec, encode); } } } // Success Response.StatusCode = 200; } } catch { // Something went wrong Response.StatusCode = 500; } } }

  • Can't send e-mail to hotmail addresses

    - by FinalFrag
    I recently did a mailing to a lot of hotmail addresses and now all the e-mails I send out (from PHP by the way) don't seem to reach their destination. So I figure hotmail banned my url... Is there any way to get rid of this ban so my e-mails will reach the users again (like activation e-mails etc)?

  • How to return a value into webpage

    Hello: I have a simple webpage that displays the credit balance for calling cards. So far without any problems, with HTML, PHP and mysql, I was able to retrieve the balance from a data base. But I have to display the result in ANOTHER PAGE, wich looks akward because the page must reload. Can I just load this value into a pre-drawed field under the input fields that collect the data from the customer? Such as : Account Number: 134556 PIN: * |send| Balance is: $12.36 Thanks in advanced

  • Connecting to an MS SQL Server from Silverlight?

    - by cam
    Normally, I would use a PHP webservice to do this, but since the front-end is hosted on a linux box, I need another way to do this (so I don't have to go through the trouble of installing FreeTDS, etc. I will if I have to). Is there a better way to do this? I'm not a web guy, but I'm trying my best.

  • How to emulate PHPs preg_split in ruby to capture offsets and delimiters?

    - by dimus
    I wonder if there is a way to get offsets and delimiters while I am splitting a string in ruby analagous to PHP preg_split: preg_split("/( |&nbsp;|<|>|\t|\n|\r|;|\.)/i", $html_string, -1, PREG_SPLIT_DELIM_CAPTURE|PREG_SPLIT_OFFSET_CAPTURE); I imagine I can achieve it by traversing string by characters or using something heavy as treetop, but I would like to use something more convenient.

  • pagination - 10 pages per page

    - by arthur
    I have a pagination script that displays a list of all pages like so: prev [1][2][3][4][5][6][7][8][9][10][11][12][13][14] next But I would like to only show ten of the numbers at a time: prev [3][4][5][6][7][8][9][10][11][12] next How can I accomplish this? Here is my code so far: <?php /* Set current, prev and next page */ $page = (!isset($_GET['page']))? 1 : $_GET['page']; $prev = ($page - 1); $next = ($page + 1); /* Max results per page */ $max_results = 2; /* Calculate the offset */ $from = (($page * $max_results) - $max_results); /* Query the db for total results. You need to edit the sql to fit your needs */ $result = mysql_query("select title from topics"); $total_results = mysql_num_rows($result); $total_pages = ceil($total_results / $max_results); $pagination = ''; /* Create a PREV link if there is one */ if($page > 1) { $pagination .= '< a hr_ef="?page='.$prev.'">Previous</a> '; } /* Loop through the total pages */ for($i = 1; $i <= $total_pages; $i++) { if(($page) == $i) { $pagination .= $i; } else { $pagination .= '< a hr_ef="index.php?page='.$i.'">'.$i.'</a>'; } } /* Print NEXT link if there is one */ if($page < $total_pages) { $pagination .= '< a hr_ef="?page='.$next.'"> Next</a>'; } /* Now we have our pagination links in a variable($pagination) ready to print to the page. I pu it in a variable because you may want to show them at the top and bottom of the page */ /* Below is how you query the db for ONLY the results for the current page */ $result=mysql_query("select * from topics LIMIT $from, $max_results "); while ($i = mysql_fetch_array($result)) { echo $i['title'].'<br />'; } echo $pagination; ?>

  • Wrong data retrieved from database

    - by holyredbeard
    So, I want to retrieve the order of the elements of a list. The order is set before by the user, and are stored in the table below. Because I also want to retrieve name and description of the list elements I need to combine two tables (see below). However, what is actually retrieved is an array containing 16 elements (should be four because it only exists four elements as for now). The array is too long to post here, but I put it in a phpFiddle to be found here if you're interested. Well, I have really tried to find what's wrong (probably something easy as always), but with no luck. Thanks a lot for your time and help! listModel.php: public function GetOrderedElements($userId, $listId) { // $userId = 46 // $listId = 1 $query = "SELECT le.listElemId, le.listElemName, le.listElemDesc, lo.listElemOrderPlace FROM listElement AS le INNER JOIN listElemOrder AS lo ON le.listId = lo.listId WHERE lo.userId = ? AND lo.listId = ? ORDER BY listElemId"; $stmt = $this->m_db->Prepare($query); $stmt->bind_param("ii", $userId, $listId); $listElements = $this->m_db->GetOrderedElements($stmt); return $listElements; } database.php: public function GetOrderedElements(\mysqli_stmt $stmt) { if ($stmt === FALSE) { throw new \Exception($this->mysqli->error); } if ($stmt->execute() == FALSE) { throw new \Exception($this->mysqli->error); } if ($stmt->bind_result($listElemId, $listElemName, $listElemDesc, $listElemOrderPlace) == FALSE) { throw new \Exception($this->mysqli->error); } $listElements = array(); while ($stmt->fetch()) { $listElements[] = array('listElemId' => $listElemId, 'listElemName' => $listElemName, 'listElemDesc' => $listElemDesc, 'listElemOrderPlace' => $listElemOrderPlace); } var_dump($listElements); $stmt->Close(); return $listElements; } from the database: listElemOrder: listElemOrderId | listId | listElemId | userId | listElemOrderPlace 1 1 1 46 1 2 1 2 46 4 3 1 3 46 2 4 1 4 46 3 listElement: listElemId | listElemName | listId | listElemDesc | listElemOrderPlace 1 Elem A 1 Derp NULL 2 Elem B 1 Herp NULL 3 Elem C 1 Lorum NULL 4 Elem D 1 Ipsum NULL Note: 'listElemOrderPlace' in the table listElement is the final order of the elements (all users average), not to be mixed with the one with the same name in the other table, that's only a specific user's order of the list elements (which is the interesting one in this case).
