c# - A default varbinary(max) value for image -


i have web application has user insert images. finding way set default varbinary(max) value in database (sql server 2008). maybe facebook has default profile picture once sign up. able upload images database , display out. able generate image pdf file (if image column not null) else error decoding image, need default varbinary(max) image represent column of image not inserted. please me out in need of project.

if looking @ storing files/images recomend looking @ filestream overview

much of data created every day unstructured data, such text documents, images, , videos. unstructured data stored outside database, separate structured data. separation can cause data management complexities. or, if data associated structured storage, file streaming capabilities , performance can limited.

filestream integrates sql server database engine ntfs file system storing varbinary(max) binary large object (blob) data files on file system. transact-sql statements can insert, update, query, search, , filestream data. win32 file system interfaces provide streaming access data.

filestream uses nt system cache caching file data. helps reduce effect filestream data might have on database engine performance. sql server buffer pool not used; therefore, memory available query processing.

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
