Matlab creates empty file when compiled and deployed -

-

im developing matlab app generates config.ini file during run. when run code in matlab works fine , ini files generated expected. when compile code, using matlab compiler (mcc) , run executable generates empty config ini. idea why different output compiled vs. not-compiled?

this code printing

fid = fopen(file_name, 'w');  if (fid ~= -1)     str = obj.tostring();     fprintf(fid, '%s', str);      fclose(fid);     status = true; else     status = false;     return; end

system ubuntu 12.04, matlab 2015b

resolved - problem in order generate new config read empty config templete. running within matlab need provide file name (as on build path) , when deployed need provide full path of template config...so file generated empty because there no string loaded template...

i have postgresql db number of tables. if query: select column_name information_schema.columns table_name="my_table"; i list of columns returned properly. however, when query: select * "my_table"; i error: (programmingerror) relation "my_table" not exist 'select *\n "my_table"\n' {} any thoughts on why can columns, can't query table? goal able query table. you have include schema if isnt public one select * <schema>."my_table" or can change default schema show search_path; set search_path my_schema; check table schema here select * information_schema.columns for example if table on default schema public both works ok select * parroquias_region select * public.parroquias_region but sectors need specify schema select * map_update.sectores_point

asp.net mvc - breakpoint on javascript in CSHTML? -

-
i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
