.net - Reading binary files -

-

although suspect know answer, interested in people's responses.

currently, have vc6 app running on w2k3 reads text file using following(simplified code):

string line; ifstream infile("test.txt",ios::in); while (!infile.eof()) {    getline(infile,line); } ...

each record in file has fields pipe delimited , code works fine crlf, although fields , records not fixed length. issue file going binary due data being unsigned packed decimal in addition text. basically, code above still valid if opened binary file(delimiters , lf retained)? tried quick test dummy data , appeared behave same.

it understanding binary files read w/the knowledge of data content bytes can retrieved , w/o lf's. i've searched around web , found various options c++ , other .net languages(an option), none seem capable of reading 1 line @ time -- if variable sized data , lf seem defeat purpose of using binary file -- , not want read entire file in 1 shot since quite large(hoping not read 1 char @ time either).

so if above might valid, there risk of data loss? if not, other options appreciated. , if missing here, please feel free elaborate.

if rely on rows being limited crlf if binary data has crlf you'll false line break. also, if binary data contains value 124 (vertical pipe) you'll have issues determining columns.

i trying use snmp4j snmp bulkget. when ever use snmp4j make call returned responseevent error says "general variable binding error" , data returned equal null. to debug: print out, console, exact oid , version number using in snmp4j. use printed out data snmpwalk on command line. valid results. know sending snmp4j correct pdu correct oid, version number, max repititions, etc. i have used snmp4j , code wrote succesffuly monitor other devices years. don't know different time. leaving me stumped. why "general variable binding error?" causes error? ideas debug? can reproduced? if so, first action should using wireshark or microsoft network monitor capture network packets. my guess agent gives generr response, not surprising, http://www.ietf.org/rfc/rfc1157.txt

the following code takes xmlnode data type , populates dataset object xmlnode content. write dataset's content file. public void populatedataset(xmlnode node) { xmlnodereader reader = new xmlnodereader(node); dataset ds = new dataset(); ds.readxml(reader); system.guid guid = system.guid.newguid(); string name = string.format("{0}{1}_{2}.xml", utility.xmloutputpath, utility.xmloutputfilename, guid.tostring()); //need write "node empty" file if xmlnode object empty of null ds.writexml(name, xmlwritemode.ignoreschema); } the problem encountered 1 scenario not write content file. how determine if xmlnode object null or empty? you can check if node parameter null or has innertext or innerxml properties null or empty, when enter method before creating xmlnodereader .
