I tried to run a simple dark GDK tutorial program:

#include "DarkGDK.h"

void DarkGDK ( void )
{
dbSyncOn ( );
dbSyncRate ( 60 );
dbCreateAnimatedSprite ( 1, "animatedsprite.png", 4, 4, 1 );
dbSprite ( 1, 0, 0, 1 );
while ( LoopGDK ( ) )
{
dbPlaySprite ( 1, 1, 16, 200 );
dbSync ( );
}
return;
}

and I get these Runtime errors:
"Failed to get device caps"
"Failed to find valid stencil buffer"
"Unable to create device"
"unable to setup 3D device"

why do i get those errors, and how can i resolve them?

thanks,

Moshe

I don't really know, but it sound slike your graphics card is very old, and doesn't support this. Or maybe you don't have correct DirectX?

I blame the video card...otherwise it wouldn't even try, I think.

Do you know how to run dxdiag.exe? (Its dirt simple, START/RUN...type in dxdiag, press ok) When the progress bar at the bottom left stops, you can see the DirectX version on the first tab, and the Display tab will tell you about your graphics card.

You need DirectX 9c from August of 2007 (at least).

No... not at least... You need the Aug2007 DXSDK at least AND at most... You need that SDK for DGDK to run properly... Others may work but each SDK is different...

And I don't think the problem is a missing DXSDK because then wouldn't the compiler be complaining about a whole bunch of link errors? Whereas if you're graphic card fails it is more likely to say such stuff...

NOTE: If my rambling makes no sense please tell me to shut up...

...Makes sense to me, Core2uu. They are runtime errors, and not compile/link errors.

There are only a few errors that make those functions fail.
The first failure is from GetDeviceCaps. Here are the possible errors:
D3DERR_INVALIDCALL
D3DERR_INVALIDDEVICE
D3DERR_OUTOFVIDEOMEMORY
D3DERR_NOTAVAILABLE : Occurs when the desktop is locked.

The other errors relate to the data that the first function failed to get.

Does this happen the first time you run GDK applications? If no, then is is likely that an application that you are running is not freeing the resources properly.

Are you running any other games, or graphics applications at the same time?

It might be possible that your graphics card is not installed correctly, or that it is otherwise configured incorrectly, has an issue with its drivers, or is just broken, or has insufficient resources (memory).
