php - Error: mysqli_fetch_array() expects parameter 1 to be mysqli_result, boolean given in -

-

इस सवाल का पहले से ही एक उत्तर है: < 33 उत्तरों 

  $ result2 =   Mysqli_query ($ con, "चयन करें * से a_option WHERE $ राशि 1 & gt; मूल्य"); जबकि ($ row2 = mysqli_fetch_array ($ result2)) {गूंज $ पंक्ति 2 ['कंपनी का नाम']। "" $ पंक्ति 2 ['उत्पाद का नाम']। ""। $ पंक्ति 2 ['मूल्य']; गूंज & lt; br / & gt; '; }   
 मूलभूत MySQL कमांड ठीक काम कर रहा है, लेकिन जब मैं परिशोधन खोज करने की कोशिश करता हूं तो यह पैरामीटर त्रुटि फेंकता है:  
  mysqli_fetch_array () पैरामीटर 1   
 में दिए गए mysqli_result, बुलियन को दिया जाता है, इसलिए केवल मुख्य कोड को पोस्ट करने के लिए डीबी के संबंध में किया जाता है।  
 कठिन है, उसी प्रश्न के इतने सारे उत्तर दिए गए हैं, कुछ कैसे इनके माध्यम से जाने के बाद मैं त्रुटि को हल नहीं कर पा रहा हूं।  
 क्या कोई एक बिंदु / त्रुटि यहाँ हल कर सकता है .... धन्यवाद !!   
 
 
 इस तरह से आपकी क्वेरी परिवर्तन में समस्या  
  SELECT * से a_option WHERE मूल्य & gt; $ Amount1;   
 यदि क्वेरी ठीक काम करती है, तो आपके कनेक्शन चर के साथ समस्या।

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# - XML - Serialize class - Some questions -

-
I have the idea of ​​serializing the properties of a class in an XML-file and then uploading this file to the server The reason for this is that I want to download this file again and read the serialized content. Then this kind of structure: file exists (myfile.xml) - & gt; Serialize the file in data from class (myclass.cs) - & gt; Upload file. Now the content may look something like this: Now the problem is, I do not know how to walk. I want the new data to be serialed in the next way, but it should be linked to that XML-file, not a new one. So I download this file and then I serialize the new data as an attachment so that it will look like this: And it should be repeated many times as I want: download file, serial new data and attach it together, then upload it again. Now, the second issue is, I want to read it. I also use XML-class for this. For the type of ultimate type, the data should be serialized, I set the square in which the assets are. But now,...
