.net - C# NetCDF Library -

-

i working on (or @ least planning) couple of projects work large amounts of repetitive data. kind of data works in spreadsheet or database, nasty in xml. :)

netcdf seems great option file format. however, work in c# , there no "official" netcdf implementation available. there "official" python version potentially use ironpython. option "netcdf library .net" on codeplex seems pretty quiet (http://www.codeplex.com/netcdf).

has worked either of these libraries? can provide recommendations?

first, sure netcdf right choice? if want interact other programs need read in large amounts of data , support netcdf, it's great choice. there aren't many standard , well-supported file formats support large multidimensional arrays. if you're going reading , writing files c#, may not such choice.

i'm big fan of "classic" netcdf file format. it's compact , extremely simple, flexible enough support lots of common kinds of multidimensional well-structured data. took me 1 day write complete parser classic netcdf, , took hour write program output well-formed special case of classic netcdf file. implement pure c# netcdf library , wouldn't trouble. start implementing features need. here's specification.

unfortunately, netcdf-4 chose use hdf-5 data format. adds lot of complexity , makes more difficult write complete netcdf parser in language. hdf-5 general-purpose , in opinion, overengineered - tries many things many people. not recommend trying work directly unless plan spend month writing unit tests. if must use netcdf-4 / hdf-5 c#, realistic option wrap c library using swig or that.

note netcdf python wrapper around c code, it's not helpful; if you're going use wrapped c library may write c# wrapper rather use python middle layer.

right now, have tool tip pops when hover on edit box. problem tool tip contains multiple error messages , in 1 long line. need have each error message on own line. error messages contained in cstring new line seperating them. my existing code below. bool ontooltiptext(uint, nmhdr* pnmhdr, lresult* presult) { assert(pnmhdr->code == ttn_needtexta || pnmhdr->code == ttn_needtextw); // need handle both ansi , unicode versions of message tooltiptexta* pttta = (tooltiptexta*)pnmhdr; tooltiptextw* ptttw = (tooltiptextw*)pnmhdr; // tchar szfulltext[256]; cstring strtiptext=_t(""); uint nid = pnmhdr->idfrom; if (pnmhdr->code == ttn_needtexta && (pttta->uflags & ttf_idishwnd) || pnmhdr->code == ttn_needtextw && (ptttw->uflags & ttf_idishwnd)) { // idfrom hwnd of tool nid = ::getdlgctrlid((hwnd)nid); } //m_errprojaccel[ch] contains 1 or more error messages each...
