objective c - NSScrollView scroll bar draws on top of all views -


i have 2 overlapping views.

  • an nstableview (the list of songs), i'll call table view
  • a layer backed nsview (for play controls @ bottom), i'll call play controls view

i using layer backed views render table view , caused scroll bar render behind play controls view, great! loaded table view 150+ rows of data app slows down pretty bad scroll.

i changed setwantslayer: no , table view snappier, great! scroll bar seems render on top of play controls view.

good:

bad:

enter image description here

any ideas whats going on here? (i'm core animation rookie if can't tell)

why don't resize entire scrollview , put play controls view below list? seems sceenshot play controls view subview of scrollview. necessary?

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!
