Can't create DirectX device on all computers
Author
This is driving me crazy! :) I have a cool little game put together and I want to share it with my friends, but half of their computers don't like how I initialize directX! I'm using 9.0c Feb release, and this code works on the 4 computers I have access to, yet I have several friends (far away) that keep failing when it tries to create the D3D device.
I have 5 different 'modes' I let them choose from via a text file and all 5 mode work on my laptop, but usually if one fails on a computer they all fail. What am I forgetting to check/setup to make this work on all computers with DirectX 9.0c installed and fairly recent video card?
char value[80] is confusing me, and if (value[0] == '1'). It looks like its neither called or assigned anything, and thus your presentation parameters are never assigned. This would fail the device from being created. On my last random thought,
int vp = 0;
should be
DWORD vp = 0;
and thus you're working with an unsigned value. And, make sure they have the same DirectX version as yours.
I hope some of this helps!

What function fails, and what error code do you get? If it's CreateDevice(), have you tried logging your presentation parameters after the call fails to see where the issue is?

Thanks for the response.
char value[80]; is just a buffer for me to read in values from a config file. The maximum line length is 80, although for parameter I'm only reading in 1 character.
For some reason the source tag isn't showing my code right,
infile >> value; // identifier "SETTING
should be:
infile << value; // identifier "SETTING
do I have to specify anything else besides {source}{/source}? (with {} = [])
Anyways, I'm just reading in a word from my settings file, which will always be a '1', '2', '3','4', or '5'. This all works on my computer - the different blocks of code do get called and the different presentation parms are with make my screen windowed/a different resolution, etc...

Yes, CreateDevice() fails.

Hrmm - is there an easy way to print the whole structure to a file, or do I have to specifically send every parameter to the file?
Thanks.

Quote:Original post by syphNope, you'd have to output each member unfortunately. However, there's "only" 14 of them, and you'll only be logging them once.

Ok, I've changed my code and sent it to my "testers" - we'll see what comes back.
In the mean time, are there a set of parameters that are _certain_ to succesfully create a D3Ddevice? (barring some kind of gross malfunction or misconfiguration on the client computer) I have a very simple 2D game with no effects others other than alphablending - you'd think I'd be able to pass a generic set of parameters that would work on virtually any machine with directx 9.0c installed.
Thanks again for the suggestions on debugging, steve the evil!

Unfortunately, nothing is certain. I suppose you could write a software render device, but that's just getting silly [smile]
You can use a very low end specification, however. 640x480x16 resolution, D3DSWAP_DISCARD, and one backbuffer should work on any 3D card (Even a voodoo 1).
Most cards today (GeForce 2+) will cope quite happily with 1024x768x32, 32-bit textures, trilinear texture filtering, etc etc.

Oh man, it *still* doesn't work on one friend's computer! I'm having him send me the graphics card info later today.
I just thought of something, however. I've been grabbing the current resolution and using that as my fullscreen width/length/format. Is it possible for a 3D card to support a particular resolution (and indeed be running at it), but not support that res in Fullscreen mode?
The error I'm getting is -2005530518 == Device does not support the queried technique.
Here are my presentation params:
Thanks again for the help.

Backbuffer format and auto depth stencil format cannot possibly be the same, yet in your structure they are both set to 22 (D3DFMT_X8R8G8B8). Even though you don't actually enable the auto depth stencil, some graphics drivers might fail the validation due to the format.
