c# - Visual Studio Extension KeyProcessor Alt Key -


cant event on alt+key. example alt+e. event firing e , alt, no alt+e mb problem in ikeyprocessorprovider? have usercontrol, , want used inner control buttonkeyproc.keydownevent+=.

[export(typeof(ikeyprocessorprovider))] [textviewrole(predefinedtextviewroles.document)] [contenttype("any")] [name("buttonprovider")] [order(before = "default")] internal class buttonprovider : ikeyprocessorprovider {     [importingconstructor]     public buttonprovider()     {     }      public keyprocessor getassociatedprocessor(iwpftextview wpftextview)     {         return new buttonkeyproc(wpftextview);     } }   internal class buttonkeyproc : keyprocessor {     internal static event keyeventhandler keydownevent;      public buttonkeyproc(itextview textview)     {     }      public override void keydown(keyeventargs args)     {         if (args.key == key.e && isalt)         {             if (keydownevent != null)             {                 keydownevent(this, args);             }         }                }      public bool isalt     {         { return keyboard.iskeydown(key.leftalt) || keyboard.iskeydown(key.rightalt); }     }

the correct code. need used args.systemkey , keyboard.modifiers.

public override void keydown(keyeventargs args) {     if (args.systemkey == key.e && (keyboard.modifiers & modifierkeys.alt) != 0)     {                 }            }

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!
