iphone - Get selected time from UIDatePicker -

-

मेरे पास एक UIDatePicker है।

मैंने < DatePicker

तो उपयोगकर्ता केवल समय का चयन कर सकता है।

उपयोगकर्ता द्वारा जो भी समय चुना जाता है, उसे टेक्स्ट बॉक्स में प्रदर्शित किया जाना चाहिए ..

मुझे पता नहीं है कि टाइम वैल्यू कैसे प्रदर्शित किया जाए - जो कि उपयोगकर्ता द्वारा डेट पिक्चर-टाइम मोड के माध्यम से सेट किया गया है।

कृपया मेरी मदद करें ..

आपको NSDate को आपके द्वारा वापस करने के लिए NSDateFormatter का उपयोग करने की आवश्यकता होगी < कोड> UIDatePicker । यहाँ कुछ अनचेस्टेड नमूना कोड है, मान लें कि आपके पास "myLabel" और "MyDatePicker" संपत्ति के रूप में एक यूआईएलबल संपत्ति है: 

  NSDateFormatter * outputFormatter = [[NSDateFormatter alloc ] इस में]; [OutputFormatter setDateFormat: @ "एच: मिमी एक"]; Self.myLabel.text = [आउटपुटफॉर्मर स्ट्रिंगफ़ॉर्मडेट: self.myDatePicker.date]; [OutputFormatter रिलीज];

आप पृष्ठ पर तिथि प्रारूप पैटर्न की जांच करना चाहते हैं > आपके स्थान पर निर्भर करता है "h: mm a" आपको "12:08 अपराह्न" जैसा कुछ देता है।

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. I found out how to locate the scroll message from WinAPI and I modified the WndProc method. Now I have this WndProc: protected override zero WndProc (Ref message message) {base.WndProc (Ref I); If (m.msg == WM_VSCROLL) {onScroll (This, New EventArgs ()); }} But the problem is, I do not know how to know about scrolling information. 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...

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...
