How do I get the size of an Iphone context -

-

मेरे पास;

CGContextRef संदर्भ = UIGraphicsGetCurrentContext ();

अब मुझे संदर्भ की चौड़ाई / ऊंचाई जानना है (पिक्सल में); ऐसा करने का कोई तरीका?

आप उस जानकारी को CGContextRef ऑब्जेक्ट, लेकिन आसपास के फ्रेम ऑब्जेक्ट से: 

  self.frame.size.width self.frame.size.height

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 #? Or any other way to find the necessary parameters about scrolling? You can define the WParam constants as the following: Private const int WM_HSCROLL = 0x114; Private Constant WM_VSCROLL = 0x115; Private contact int SBHOZZ = 0; Private Consultant SB_VERT = 1; Private Con...

c - Linux mmap() error -

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...
