java - JLabel text is garbled -


i'm seeing strange issue involving jlabel used display range of numbers. text of label typically 0.0 - 100.0 (for example). problem select few users, text appears garbled. in example, text show /-/,0//-/.

here's know far:

  • it appears sort of off-by-one bug since each character displayed 1 unicode character behind expected character.
  • the dash character between 2 numbers hard-coded in application string literal.
  • it's happening on various versions of oracle jvms including 1.6.x , 1.7.x.
  • it's happening on few select windows 7 machines.

what cause type of problem? else should investigate? thanks.

this happens when you're setting font of jlabel font corrupted in windows font cache.

to rebuild cache: administrator, delete file , reboot pc:

del %windir%\system32\fntcache.dat

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!
