My Big Problem

**why06** · 11-29-2010

Well there's been talk about making this section more active, and I suppose one way I could help is by participating in sharing my own troubles coding as well. Now the reason I haven't posted code in the longest is because I've been working on a rather large project, but about 1 month ago it grinded to a halt because I had a mysterious error. I didn't want to get help because I would have to release all my code. Even though Im all for open source I got kinda full of myself. I should have asked for help ages ago. So from now on I have decided I will make this project open source, and in the future may even make it a group project if anyone is interested.

On to the problem. The technique Im using is pretty unique. Instead of creating and destroying a font object when I need it Im creating roughly 1250 font objects. A class manages all of the fonts. When finished accessing fonts it will optimize and destroy all unneccesary pointers. It also will create new font objects when you need them and deallocate them when you don't. Its sorta like a Java-style implementation for DirectX, in that the memory allocation is handled by the class.

The problem I run into is on initializing the fonts. Now despite hours of tinkering I just don't know how to find the error. There's no way for me to debug it, because I must inject it into the D3D test environment.....

Hmm... an idea just hit me that I could in fact compile the code into an executable instead of a DLL and create my own D3D environment. That would allow me to debug it. Ofcourse Im not good at debugging. So anyone who knows any good tutorials for debuugging please let me know.

Also since the god of open source seems to have blessed me with this idea. Im going to go ahead and fulfill my promise and release the source and hope for the best:

Steal it. Leech it. Help me Improve it. I don't care. The benefit of sharing this code is greater then keeping it hidden.

u said u want to make into a dll not debug why don't u change the debug mode into realarse and hit compile. is that ur problem if not when get on my pc tomorow i will look at ur code

**why06** · 11-29-2010

When I said debug I meant using a debugger to investigate where the exception is thrown. Try injecting the file into a test environment and you will see. I do wish it were that easy though. I examined all of my code including the massive arrays of font pointers, checking to see if each one was initialized, but I think it might be something deeper, such as a physical limit to the number of fontpointers I can create. I don't really know. no one has created this many before so I couldn't find any examples.

[php]
__asm
{
int 3h
}
[/php]

Put that at the start of your main thread, run environment with loaded DLL in olly, start debugging?

**why06** · 11-29-2010

Simple solution, but I'll need to run it in a d3d enviroment or the errors won't come up.

u meam u cant injecet it in d3 test envoiment it gave u an error right

yeh pretty much.

I've got a Droid. That shit is epic.

**sam22** · 11-29-2010

who is the moderter of this section i mean minion

**why06** · 11-29-2010

Hell_Demon. Speaking of which we should probably stop going or subject...

**Hell_Demon** · 11-30-2010

DX base, add your shizzle to this and debug!

**why06** · 11-30-2010

Thanks HD. I'll load it up and see what happens. D:

**Hell_Demon** · 11-30-2010

It's the absolute minimum that I could call DX base lol =P clears background to red and presents it =P shouldn't be too hard to add endscene call or whereever you draw =P

beginscene()
present()
endscene()

in the loop and then u can just hook endscene and do what you normally do, or integrate the code into the project w/o hooking =p

can you approve his attachment so i can see what kind erro he get and help him
