PPTX converter
« on: March 07, 2011, 11:10:01 pm »
My clas has begged me to write an executable converter which they will place in the homework drive of my schools computers. My school will not allow us to install the compatibility pack and we are currently using Microsoft Office 2003. Could someone please help me in how to do this. I will do it in any compiled language i could possibly quickly learn enough of.(C++ preffered because of prior knowledge)
Thank you to anyone who might help

Hmm, I know OOo supports .pptx and lets you convert back and forth. Try that?

Or Google Docs might work.

OpenOffice.org Portable might also be a good idea, since it runs from a flash drive.

Spoiler For Projects:

My projects haven't been worked on in a while, so they're all on hiatus for the time being. I do hope to eventually return to them in some form or another...

Spoiler For Pokemon TI:
Axe port of Pokemon Red/Blue to the 83+/84+ family. On hold.

Spoiler For Nostalgia:
My big personal project, an original RPG about dimensional travel and a few heroes tasked with saving the world.
Coding-wise, on hold, but I am re-working the story.

Spoiler For Finale's Super Insane Tunnel Pack of Doom:
I will be combining Blur and Collision Course into a single gamepack. On hold.

Spoiler For Nostalgia Origins: Sky's Story:
Prequel to Nostalgia. On hold, especially while the story is re-worked.

I've used that before, and it's unfortunately slow (to start up) :( But I guess if your teachers don't want you installing stuff, that would work.

Open Office portable is too large for my flash drive. I'm almost out of space.
they want me to write a small program. Does anyone know how to do this. How do they change from pptx and ppt? If i know that I should be able to figure out how to make it work

I don't think this would be a small program. By my best guess pptx is a compressed version of ppt. I had made two identical powerpoints and saved one as a ppt and the other as pptx. I then opened up the files in a hex editor. I was able to find the text from the ppt but not in the the pptx. The format seems very complex and I doubt microsoft would be willing to give out details on it.

3. Create a partial Java virtual machine  for the Prizm (not started)
4. Create Axe for the Prizm with an Axe legacy mode (in planning phase)
5. Develop a large set of C and asm libraries for the Prizm (some progress)
6. Create an emulator of the 83+ for the Prizm (not started)

OOo might though.
