c++ - Best way to find a whitespace-delimited word in a CString -

-

उदाहरण: " कहीं से * चुनें जहां x = 1 "

मुझे " कहीं " के भीतर " जहां " नहीं है, लेकिन " जहां " सफेद स्थान-सीमांकित खोजने के लिए चाहते हैं। उदाहरण में "जहां" को रिक्त स्थान से सीमांकित किया गया है, लेकिन यह गाड़ी का रिटर्न, टैब आदि हो सकता है।

नोट: मुझे पता है कि regex करना आसान होगा (regex समकक्ष " \" Bwhere \ b "), लेकिन मैं सिर्फ यह करने के लिए अपने प्रोजेक्ट में एक regex लाइब्रेरी नहीं जोड़ना चाहता।

यदि आप स्ट्रिंग हेरफेर की शुद्ध एमएफसी पद्धति का उपयोग करना चाहते हैं, तो यह काम करना चाहिए: 

  सीएसटीिंग strSql = _T ("कहीं से * चयन करें जहां x = 1 "); Int nTokenPos = 0; सीएसटीइंग स्ट्रटोकन = स्ट्र्सकिल। टोकनइज़ (_T ("\ r \ n \ t"), एनटीकेनपोस); जबकि (! Strotoken.IsEmpty ()) {if (strToken.Trim ()। तुलना करें नोज़ (_T ("where")) == 0) वापसी सही; // मिला strToken = strSql.Tokenize (_T ("\ r \ n \ t"), nTokenPos); }  विवरण झूठा है; // नहीं मिला

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...

c - Linux mmap() error -

I have a memory map file, out of which I want to parse the content of the buffer. MMAP () achieves success, and I can successfully use fprintf to print the buffer content in the file. 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...
