    <p>after making google for long time also, i am unable to find reason/solution for crashing of xmlReaderForMemory,still with valid parameters. </p> <p>i have created two parser function using libxml,when i call individually they are working fine.But when i call one after another it is getting crashed on xmlReaderForMemory by giving error s follows:</p> <p>First-chance exception at 0x7c918fea in nayak.exe: 0xC0000005: Access violation writing location 0x00000010. Unhandled exception at 0x7c918fea in nayak.exe: 0xC0000005: Access violation writing location 0x00000010.</p> <p>now i am giving the code of the two functions:</p> <p>FIRST FUNCTION:</p> <pre><code> char* CB_omniParser(char *omnistring){ char *parseResult,; const char *fileName = omnistring; char *temp,*texttemp,*result=0; int i,len=0,error; xmlTextReaderPtr reader; len= strlen(omnistring); if(len==0) return 0; reader = xmlReaderForMemory(fileName,len,"",NULL,0); if(reader){ temp = (char *) GlobalAlloc(GPTR, sizeof(char)*len); parseResult = (char *) GlobalAlloc(GPTR,sizeof(char)*len+1); while(error=xmlTextReaderRead(reader)) { if(error==-1){ return 0; // on failure } switch(xmlTextReaderNodeType(reader)) { case XML_READER_TYPE_ELEMENT: temp = (char *)xmlTextReaderConstName(reader); strcat(parseResult,temp); strcat(parseResult,"#"); xmlTextReaderMoveToElement(reader); continue; case XML_READER_TYPE_TEXT: temp = (char *)xmlTextReaderConstValue(reader); strcat(parseResult,temp); strcat(parseResult,"|"); continue; } } xmlFreeTextReader(reader); xmlCleanupParser(); return parseResult;//on success returns the parsed omni string } else return 0; // on failure } </code></pre> <p>Second Function:</p> <pre><code> char* CB_xmlParserFromMemory(char *xmlstring){ char *xmlParseresult; char *temp; int i,len,,error;; xmlTextReaderPtr reader1; len= strlen(xmlstring); if(len==0) return 0; reader1 = xmlReaderForMemory(xmlstring,len,NULL,NULL,0); if(reader1){ temp = (char *) GlobalAlloc(GPTR, sizeof(char)*len); while(error=xmlTextReaderRead(reader1)) { if(error==-1){ return 0; // on failure } switch(xmlTextReaderNodeType(reader1)) { case XML_READER_TYPE_ELEMENT: temp = (char *)xmlTextReaderConstName(reader1); strcat(xmlParseresult,"\""); strcat(xmlParseresult,temp); strcat(xmlParseresult,"\""); strcat(xmlParseresult,":"); xmlTextReaderMoveToElement(reader1); continue; case XML_READER_TYPE_TEXT: temp = (char *)xmlTextReaderConstValue(reader1); strcat(xmlParseresult,"\""); strcat(xmlParseresult,temp); strcat(xmlParseresult,"\""); strcat(xmlParseresult,","); continue; } } xmlCleanupParser(); xmlFreeTextReader(reader1); GlobalFree(temp); return xmlParseresult;//on success returns the parsed omni string } else return 0; // on failure } </code></pre> <p>both the functions are working individually fine.but if i call one function after another then both crashes at above given place...ith same error..plz help me.....</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
