c# - using Microsoft.Office.Interop Word and Excel -

-

i using microsoft.office.interop, scanning word , excel files using c#,i taking file input user, saving on local directory scanning interop library. working fine on local publish, when published on server not scanning word or excel files. have ms-office installed on server, same version have on pc. else need do? have copied required dll's in bin directory. how reading word file

public static string word_to_text(string source) {   word.application newapp = new word.application();    object source = source;   object unknown = type.missing;    object miss = system.reflection.missing.value;   object readonly = true;   microsoft.office.interop.word.document docs = newapp.documents.open(ref source, ref miss, ref readonly, ref miss, ref miss, ref miss, ref miss, ref miss, ref miss, ref miss, ref miss, ref miss, ref miss, ref miss, ref miss, ref miss);   string totaltext = "";   (int j = 0; j < docs.paragraphs.count; j++)   {     totaltext += " \r\n " + docs.paragraphs[j + 1].range.text.tostring();   }   docs.close();   newapp.quit();   return totaltext; }

i getting exception

retrieving com class factory component clsid {000209ff-0000-0000-c000-000000000046} failed due following error: 80070005 access denied. (exception hresult: 0x80070005 (e_accessdenied)).

i fixed following this post having issue excel , word files. in case of word files,its not reading file above code,docs object appearing null. in case of excel showing exception

microsoft office excel cannot access file 'myfile path'. there several possible reasons: • file name or path not exist. • file being used program. • workbook trying save has same name open workbook.

i read solution give rights folder, , create desktop folder inside system32 here,both solutions not worked me :( issue arising when publishing it

you should not use office automation in server. 1 thread can access word @ time, it's slow relative other options, , word not made server-side execution.

much better use openxml sdk:

or other wrapper:

http://docx.codeplex.com/

http://www.codeproject.com/articles/87711/manipulate-docx-with-c-without-microsoft-word-inst

if feel absolutely must use office automation on server (and shouldn't), @ least put in separate process , enque requests other process. way can ensure 1 request being processed @ time, can safely grant other process permissions needed, , if word halts can kill , secondary process.

i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
