blob

问题 I'm building an application from Flash Builder 4.5. I'm a newb to SQLite and here's where my questions come in! I've got 3 columns in an SQLite db I built with Firefox's handy SQLite Manager. So, I created 3 columns, an index/reference that's just an incrementing INTEGER for easy reference, a descriptive title of the image (so it can be searchable later) in a TEXT, and a BLOB type that holds the pngs. I'm trying to add this in an assets folder into my project (as a pre-populated database) and

问题 This question already has answers here : displaying an image stored in a mysql blob (3 answers) Closed 4 years ago . As I plan to dig deep, here I am trying to store images into my database. I do realize that storing images in the database is not recommended and is considered "bad" but practically, I think it requires one or more dedicated servers for file count limit. Ps.

问题 We are in the process of porting our HTML application to Windows 8 using Cordova/Phonegap 3.1.0. Most of it runs fine; however when we take a photo using the FILE_URI navigation, we receive what initially looks like a blob, but is just a string (I believe). An example string I get back when using the following code, could be: blob:00000000-0000-0000-0000-000000000000 Using: navigator.camera.getPicture(success, failure, { quality: 40, destinationType: Camera.DestinationType.FILE_URI,

问题 I am trying to extract a TIF file from an oracle database. Most of the files that are converted from a blob work fine, but some files seem to be missing a few kilobytes. For example, when I extract a file using the SQL GUI I get a TIF file that is 912,390 bytes in size. When I use my method, I get a file that is 909,312 bytes in size. The missing 3078 bytes means I can't open the file. What am I doing that is causing the files to be incomplete? //... if ((FileOutDir != null) && (blobSQL !=

问题 I've been trying to upload file to Azure storage using VBA in Microsoft Access but so far without success. I have had a good search around and have found some code which looks promising but I can't get it to work. Seems like many others have been looking for a similar solution or help with working with Azure from VBA. This is the code; Private Function pvPostFile(sUrl As String, sFileName As String, Optional ByVal bAsync As Boolean) As String Const STR_BOUNDARY As String = "3fbd04f5-b1ed-4060

问题 I'm pretty unfamiliar with video streaming. Does anyone know of a page that gives an example of all the steps involved in setting up a web page to stream a video from blob storage? Ideally using FLASH player, not silverlight. I have a website in Azure that has a page with flash player. It works just fine if I include the MP4 video file in the VS project folder, but if I change the file name to the URL of the same video file in BLOB storage, I get a blank display. Videos are made and provided
