I’ve found. It was so simple that I didnt even see it… /** * @param {Blob} videoFile * @param {HTMLVideoElement} videoEl * @returns {void} */ function display( videoFile, videoEl ) { // Preconditions: if( !( videoFile instanceof Blob ) ) throw new Error( ‘`videoFile` must be a Blob or File object.’ ); // The `File` … Read more
The spec compliant answer is object-src ‘self’ blob: blob: should only match blob: explicitly, and not ‘self’ or *. This is a bug in Chrome, and was recently fixed in Firefox 40.
Try this using, this or useragent if (navigator.appVersion.toString().indexOf(‘.NET’) > 0) window.navigator.msSaveBlob(blob, filename); else { var blob = new Blob([‘stringhere’], { type: ‘text/csv;charset=utf-8’ }); var link = document.createElementNS(‘http://www.w3.org/1999/xhtml’, ‘a’); link.href = URL.createObjectURL(blob); link.download = ‘teams.csv’; link.click(); }
You can insert into a varbinary(max) field using T-SQL within SQL Server Management Studio and in particular using the OPENROWSET commmand. For example: INSERT Production.ProductPhoto ( ThumbnailPhoto, ThumbnailPhotoFilePath, LargePhoto, LargePhotoFilePath ) SELECT ThumbnailPhoto.*, null, null, N’tricycle_pink.gif’ FROM OPENROWSET (BULK ‘c:\images\tricycle.jpg’, SINGLE_BLOB) ThumbnailPhoto Take a look at the following documentation for a good example/walkthrough Working With … Read more
Don’t use BlobBuilder in Chrome (tested in OSX Chrome, Firefox 12, Safari 6, iOS Chrome, iOS Safari): ex1 : http://jsfiddle.net/malraux/xGUsu/ (principle) ex2: http://jsfiddle.net/xGUsu/78/ (working with full example) var xhr = new XMLHttpRequest(); xhr.open(‘GET’, ‘doodle.png’, true); xhr.responseType=”arraybuffer”; // Process the response when the request is ready. xhr.onload = function(e) { if (this.status == 200) { // … Read more
You said “I checked the mysql schema and it remains varchar(255)” – did you expect Hibernate to automatically alter your database? It won’t. Even if you have hibernate.hbm2ddl.auto set, I don’t believe Hibernate would alter the existing column definition. If you were to generate new database creation script, @Lob should generate “TEXT” type column if … Read more
the mySql blob class has the following function : blob.getBytes use it like this: //(assuming you have a ResultSet named RS) Blob blob = rs.getBlob(“SomeDatabaseField”); int blobLength = (int) blob.length(); byte[] blobAsBytes = blob.getBytes(1, blobLength); //release the blob and free up memory. (since JDBC 4.0) blob.free();
When your DB grows bigger and bigger it will become harder to backup. Restoring a backup of a table with over 100 GB of data is not something that makes you happy. Another thing that get is that all the table management functions get slower and slower as the dataset grows. But this can be … Read more
You can test if it is an instanceof Blob like this: var MyBlob = new Blob([‘test text’], {type : ‘text/plain’}); document.body.innerHTML = MyBlob instanceof Blob; This will work for things that inherit from Blob also.
