need help with code from a book

need help with code from a book

• Remy Baek

  Does the book have any full example projects you can run I can't help but feel that if you've copied this code right, some other previous step must be missing. Assuming that there hasn't been a change to DX since the book came out. You should also check if there are errata on any website.
  

  I see it came with a CD, is there a full project on there you can try to build and run that uses this code

  sorry about posting the code like that (please Tom don't sue me for it), the only reason i posted it is because i wrote it following examples from the code so i didn't think it'd be a huge deal because it isn't the full game code. anyway, i apologize for posting it, and i'll remove the zips from my webspace. sorry for any trouble i caused.
  
  i'll try those suggestions zman. i'll have to get to them after work today, and i'll reply if its resolved or not. thanks for the help

  The 1st thing to do is to go into Debug/Exceptions and change 'When the exception is thrown' to 'break into the debugger'. The framework from the book (and the one in the SDK) have a lot of try catch statements in them so you *never* see the actual line the error happened on.

  So once you have done that and you run the code you will see that its trying to load the media file. From what I can make out you have hardcoded the location of the media files in app.config to be c:\media\blockers. My guess is that its not finding the media files there because that's not the default place the CD copies them to I copied the media files from the CD into c:\media\blockers and the code works. Well I get a black screen but no exception.

  You should also be very careful posting copyright files without permission. I have no idea if Tom is OK with the code and media being posted. My updates on The ZBuffer not only have permission, but I only post the changed files and no media. I've edited your posts to remove the links. You should probably remove the files.

  I had this problem, this forum solved it, indirectly. My problem was in the App.config file, where i missed off the trailing backslash in the media path. Took me hours to find this forum... Anyway, If anyone else wonders, device from the book should be e.Device (or put in a using block suggested on other forums) and if it compiles the exception is probably a missing file. Now i can see my program!! (well Tom's program) =)

  i hope you're not pissed that i posted in both places.
  
  ok, so here's the deal with his code.  he's trying to show us how to render a mesh with directx from a file.  if you look at his regular code (like the stuff hosted at zbuffer, which i have downloaded just so you know), he implements this differently than he does in the example, because in the full code he has other classes created already for rendering screens and menus and such.  the actual code is executed elsewhere in the program. 
  
  so that you can see it, i uploaded it to my webspace for download

  if you'd be so kind, download it and see for yourself what's happening.  thanks for your time guys

  let me know if you figure anything out from this, thanks for replying

  is this forum not functional in firefox   clicking edit completely blanks out my post
  
  anyway, the code link is wrong, here it is:

  I see the CreatingDeviceException wraps the actual exception thrown. If you change put a breakpoint in this line :

  DisplayErrorMessage(new CreatingDeviceException(e));

  and then examine e, what is the error actuall being thrown

  
  
  

• SteffenRuland

  As mentioned in your duplicate post on gamedev.net. You can download/get the updated code from the ZBuffer. This should give you a boost in the right direction and should provide you with a solid base to work from.
  
  I hope this helps.

  yeah, seems to work just fine now. i guess i had the path wrong, but i copied and pasted it from the explorer bar i thought. oh well, whatever, my mistake. thanks so much for pulling my head out of my butt! :P
