8 Mar 2019 ... In this article, I will explain how to open a PDF file in a web browser using ASP . NET . LocalBusinessSearch.UIEventHandlers.AddToFavoritesClick = function() { if (LocalBusinessSearch.currentBusiness && !LocalBusinessSearch.currentIsFavorite) { LocalBusinessSearch.Data.FavoritesStore.add( LocalBusinessSearch.currentBusiness); LocalBusinessSearch.currentIsFavorite = true; LocalBusinessSearch.showFavorites(); Ext.get("fav_" + LocalBusinessSearch.currentBusiness.id).highlight( "#ffff00", { attr : "background-color", endColor : "ffffff", duration : 1} ); var tr = Ext.getCmp("tabResults"); var sm = tr.getSelectionModel(); if (sm.getCount() != 0) { sm.clearSelections(); } } }; The job of this method is to add the current BusinessRecord, assuming it is selected and assuming it isn t already a favorite (which happens to be the first check performed here) to the saved favorites. The add() method of the FavoritesStore is called, passing it the LocalBusinessSearch.currentBusiness, which triggers the call to the DAO s createFavorite() method. After that, LocalBusinessSearch.currentIsFavorite is set to true, since the business being viewed is in fact now a favorite, and a call to LocalBusinessSearch.showFavorites() is called, which updates the list of favorites on the screen. Now we use a little more Ext.Fx: a reference to the newly added favorite is obtained, and the highlight() method is used to do a Yellow Fade Effect.3 This is an effect whereby you highlight a changed piece of information in yellow and then slowly fade it back to the nonhighlighted state. Of course, it does not have to be yellow, and it does not have to fade, but the underlying concept is the same: highlight changed information to provide a visual cue that something has happened (remember that changes caused by Ajax or other UI interactions can sometimes be subtle, so anything you can do to help people notice them will be appreciated). The highlight() method accepts as its first argument an RGB value specifying the color to highlight the item in. As its second argument, the method accepts an object that configures the item, including specifying the style attribute c# display pdf in window: how to export rdlc report to pdf without using reportviewer c# : Extract ... c# wpf document viewer pdf PDF File Writer C# Class Library (Version 1.22.0) - CodeProject

This function first ensures that the upload location exists and is writable, which will help us solve any permissions errors if the upload area hasn t been created properly. Then the ranking value for the image is determined, based on the other images that have been uploaded for the blog post. The ranking system simply uses numbers from 1 to N, where N is the number of images for a single post. Since the new image is considered to be the last image for the blog, we can use the SQL max() function to determine its ranking. The only problem with this is that if no images exist for the given blog post, a value of null is returned. To avoid this problem, we will use the coalesce() function, which returns the first non-null value from its arguments. The code for preInsert() is shown in Listing 11-14. Listing 11-14. Ensuring the File Can Be Written, and Determining Its Ranking (BlogPostImage.php) < php class DatabaseObject_BlogPostImage extends DatabaseObject { // ... other code public function preInsert() { // first check that we can write the upload directory $path = self::GetUploadPath(); if (!file_exists($path) || !is_dir($path)) throw new Exception('Upload path ' . $path . ' not found'); if (!is_writable($path)) throw new Exception('Unable to write to upload path ' . $path); // now determine the ranking of the new image $query = sprintf( 'select coalesce(max(ranking), 0) + 1 from %s where post_id = %d', $this->_table, $this->post_id ); $this->ranking = $this->_db->fetchOne($query); return true; } // ... other code > pdf viewer in asp.net using c# Create/Read Advance PDF Report using iTextSharp in C# .NET: Part I

Finally, we will implement the postInsert() callback. This is the function responsible for copying the image file from its temporary upload location to the uploaded files area of our web application. We will do this in postInsert() because if any SQL errors occurred before this point, the whole transaction could be easily rolled back, preventing the file from being incorrectly moved into the web application. To move the file, we will use the PHP move_uploaded_file() function. This function is used for security reasons, as it will automatically ensure that the file being moved was in fact uploaded via PHP This function will return true if the file was successfully moved and false . if not. Thus we can use the return value as the postInsert() return value. Remember that returning false from this callback will roll back the database transaction. In other words, if the file could not be copied for some reason, the database record would not be saved. Listing 11-15 shows the postInsert() method, which completes the image-upload functionality for the web application. Listing 11-15. Moving the Uploaded File to the Application File Storage Area (BlogPostImage.php) < php class DatabaseObject_BlogPostImage extends DatabaseObject { // ... other code public function postInsert() { if (strlen($this->_uploadedFile) > 0) return move_uploaded_file($this->_uploadedFile, $this->getFullPath()); return false; } // ... other code } > Once you have added this code, you will be able to upload images to blog posts via the form we added to the post preview page. Currently, though, we haven t implemented code to display these uploaded images, so to verify that your code is working, you should check that there are records present in the database table by using the following query: mysql> select * from blog_posts_images; You should also check that the file you uploaded is in /var/www/phpweb20/data/uploaded-files.
