c++ - "error LINK2019: unresolved..." -


i'm trying compile test program using visual studio 2012 written in c++, program computes inverse of arbitrary matrix using armadillo linear algebra library. requires enable lapack in armadillo's config.h file , link libraries/dlls in project's properties (which i've done).

i'm compiling 64bit release i've downloaded suitable blas/lapack libraries here , have linked vs project against them. having done i'm still getting link errors whilst trying use armadillo's inv(...) method follows:

1>matrix.obj : error lnk2019: unresolved external symbol dgetrf_ referenced in function "public: static double __cdecl arma::auxlib::det_lapack<double>(class arma::mat<double> const &,bool)" (??$det_lapack@n@auxlib@arma@@sanaebv?$mat@n@1@_n@z) 1>matrix.obj : error lnk2019: unresolved external symbol dgetri_ referenced in function "void __cdecl arma::lapack::getri<double>(long *,double *,long *,long *,double *,long *,long *)" (??$getri@n@lapack@arma@@yaxpeajpean00100@z)

can give me slight indication i'm doing wrong? many in advance!

the examples provided armadillo should compile out of box. open project files in examples/example1_win32 folder. may want use them starting point code.

alternatively, site might useful: armadillo blas , lapack in 64 bit visual c++ projects

using 64 bit lapack , blas considerably faster 32 bit versions. may want using intel mkl, provides high-speed multi-core implementation of lapack.

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!

i have buttona , when buttona clicked, want keyboard show uitextfield in inputaccessoryview. there way have keyboard show manually , set inputaccessoryview without having uitextfield initially? thanks. you cannot summon keyboard without object can become first responder. there 2 ways work around: subclass uiview , implement uikeyinput protocol in it. example: in .h file: @interface inputobject : uiview<uikeyinput> @property (nonatomic, copy) nsstring *text; @property (nonatomic, strong) uiview *inputaccessoryview; // must override inputaccessoryview , since it's readonly default @end in .m file, implement protocol: - (bool)canbecomefirstresponder { return yes; } - (bool)hastext { return [self.text length]; } - (void)inserttext:(nsstring *)text { nsstring *selftext = self.text ? self.text : @""; self.text = [selftext stringbyappendingstring:text]; [[nsnotificationcenter defaultcenter] postnotificationname:kinputobjec
