c# - Error while converting PPT to PDF -

-

i trying make application converts docx/xls/ppt pdf.

  1. conversion of docx , xls requires microsoft.office.core dll
  2. conversion of ppt requires office.dll

i converted 1 , 2 separately when try merge both of them i.e

when try add both reference (microsoft.office.core dll , office.dll) gives me error.

so, there problem in adding both dll's ?

229 error of same kind ---- error 1 cannot embed interop type 'microsoft.office.core.msoblogimagetype' found in both assembly 'e:\all pdf\watermark_pdf\pdf merger , protector source code\pdfmerger\obj\debug\interop.microsoft.office.core.dll' , 'c:\program files\microsoft visual studio 10.0\visual studio tools office\pia\office12\office.dll'. consider setting 'embed interop types' property false.

note - had changed "embed interop types" property false both dll's.

please help.

just use specific libraries: 

using excel = microsoft.office.interop.excel; using word = microsoft.office.interop.word; using power = microsoft.office.interop.powerpoint;

they should have need along not having namespace isssues between interlocking dll's

these found com references

edit: also, using correct namespaces? if post code helpful.

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...
