database - Escaping Characters Rails -

-

I want to escape from the input in this form so that when entering database characters. * * Will not be affected New How do I encode the characters to get the above mentioned target 

  & lt;% form_for @ post ,: url = & gt; {: Action = & gt; : CreateInnovation} | Farm | & Gt%; & Lt; Fieldset & gt; & Lt; P & gt; Title: & lt; Br / & gt; & Lt;% = form.text_field: title,: html = & gt; {: Class = & gt; "Text ui-widget_content ui-corner-all"}%> & Lt; / P & gt; & Lt; P & gt; Details: & lt; Br / & gt; & Lt;% = form.text_area: body ,: html = & gt; {: Class = & gt; "Text ui-widget_content ui-corner-all"}%> & Lt; / P & gt; & Lt; / Fieldset & gt; & Lt;% end% & gt; In order to prevent SQL injection, ActiveRecord will automatically avoid any characters as any character

Are you worried about this? If so, the train has covered you.

c# - ListView onScroll event -

-
I am programming a simple C # application, and I need a Scallow event on the list view. So I inherited the original ListView class created in ListviewEx witch.

This data should be in wParam, but there is a LOWORD macro ++ like in C in C # and I switch to find the criteria like SB_ below, SB_ENDSCROLL, SB_PAGEUP etc. there any way Need to change the LOWORD macro from C #?

However, when I try to access Buffer as an array in my program directly, I get a partition error. Why is this happening? Here's the code: #define PTT_DUMP "/ home / druru / somefile". . Int fd_ptt_dump = Open (PTT_DUMP, O_RDONLY); Structure state struct_ptt_dump; Fstat (fd_ptt_dump, & amp; struct_ptt_dump); Printf ("\ n \ n \ t \ t \ t --- Size of dump =% d ----- \ n \ n", struct_ptt_dump.st_size); Four * membuffer; Four pid_num [100]; Four cycles [100], examples [100], CPI [100]; Int pid_index = 0; Int cycles_index = 0; Int instr_index = 0; Int cpi_index = 0; Int len ​​= (int) struct_ptt_dump.st_size; Int newline_count = 0; Int n = 0; If ((membuffer = mmap (0, struct_ptt_dump.st_size, PROT_READ, MAP_FILE | MAP_PRIVATE, fd_ptt_dump, 0)) == (caddr_t) -1) err_sys ("mm...
