[tim007]

No it didnt work ..couldnt get the dll

[vel]

hi did you get the solution for this convertion problem.

No it didnt work ..couldnt get the dll

Looks like you need a 3rd party DLL to use his solution.

Actually...ther e is no native PDF functionality, so you will need a third-party dll regardless. I suggest either searching for the one he used (start here, i found this from a quick google search) and if you can't find it, move on to Sourceforge. They have plenty of .NET PDF solutions.

Seems to be a great converter?
