my code 

    imports system.web.security     imports system.data     imports system.data.oledb     imports system.configuration     imports system.web.configuration      partial class registration     inherits system.web.ui.page      protected sub button1_click(byval sender object, byval e system.eventargs) handles button1.click         dim connstring string = "provider=microsoft.jet.oledb.4.0;data source=|datadirectory|onlineregistration.mdb"         dim sqlstring string = "insert registration (firtsname, telephone, email, paswords) values (?,?,?,?)"         using conn new oledbconnection(connstring)             using cmd new oledbcommand(sqlstring, conn)                 cmd.commandtype = commandtype.text                 cmd.parameters.addwithvalue("firtsname", textbox1.text)                 cmd.parameters.addwithvalue("telephone", textbox2.text)                 cmd.parameters.addwithvalue("email", textbox3.text)                 cmd.parameters.addwithvalue("paswords", textbox4.text)                 conn.open()                 cmd.executescalar()             end using         end using     end sub  end class

that error "must use updateable query" tipically thrown when mdb file write-only, or when there no write permission on file.

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!
