c - calculation of the length of the file doesn't work -

- 

  # शामिल "stdio.h" #include "stdlib.h" int main () {FILE * fp; Int noOfLines = 0; Char fname [] = "Rtl_Prod_Id.txt"; printf (fname); fp = fopen (fname, "आर"); चार च; // हर लाइन के लिए looping करें {ch = fgetc (fp); अगर (ch == '\ n') noOfLines ++; } जबकि (ch! = EOF); // अंतिम पंक्ति से पहले लाइन अगर (ch! = '\ N' & amp; amp; NoOfLines! = 0) noOfLines ++; fclose (एफपी); printf ( "% d", noOfLines); वापसी 0; }   
 मैं बस मेरी फाइल में लाइनों की संख्या की गणना करने की कोशिश कर रहा हूँ वही मुझे कोई परिणाम नहीं लौटाता है  
 मैं क्या कर रहा हूँ जो संभव गलतियाँ हैं  
 पर्यावरण: एएक्स और कंपाइलर: सीसी  
 धन्यवाद  
  संपादित करें: मेरे प्रोग्राम को सफलतापूर्वक संकलित किया जाता है, लेकिन इसे निष्पादित करते समय। ओट फाइल में यह कुछ भी चालू नहीं होता   
 पीएस:  हालांकि मुझे जवाब मिल गया है। करने के लिए धन्यवाद  । मुझे  चार च;  से  int ch;  बदलना पड़ा। लेकिन मुझे आश्चर्य है कि क्यों? चार घोषणाओं में क्या गलत है? । जैसा कि मैं '\ n' और EOF वर्णों की जांच करने जा रहा हूं, इसलिए पूर्णांक क्यों?    
 
 
 यह एक जंगली शॉट है, लेकिन लाइन को बदलने  
  चार च;   
 से  
  int ch;   
 उपयुक्त है  fgetc  का वापसी प्रकार है  int , नहीं  char ।

I have recently switched to autotools to cement, since the limiter cross platform is better for development and what I saw When I build a stable library of my C ++ code, all the files inside .cpp.o is a suffix ar income tax PA8 / libgenericTZR.a genericTZR.cpp.o I have seen other libraries made by other tools and they do not do it, I'm not sure this is the realm And there is a bad thing, but how can I create static libraries without cpp file extension? This is my CMake file add_executable (PA8 ISP_Charges.cpp genericTZR.cpp genericTZR.h) set (LIBSRC genericTZR.c genericTZR.h) add_library (genericTZR shared $ {LIBSRC}) add_library (genericTZR shared $$ TARGET_OBJECTS: myObjects & gt;) install add_library (Generic TZR-static static $ {LIBSRC}) set_target_properties (Generic TZR-Static Properties OUTPUT_NAME $ install (TARGETS PA8 DESTINATION BIN) TARGETS GENICTZR GENERICTZR-STATIC DESTINATION lib) Installed (files "$ {PROJECT_BINARY_DIR} /PA8/genericTZR.h...

c# - Check if a NumericUpDown has no value -

-
How can I check that the user left a NumericUpDown control blank? I have looked at another question to examine the 'text' property but there is no text property to check against it. You can check against the text property, though it is a designer and Is hidden from Intelligence. Just try this sample it works: if (string.IsNullOrEmpty (control.Text)) {// a value}
