the first post example didn't work for me either.

I just read through the thread.

CLS by itself is different then CLS with a color value

There is a CLS in the Core commands for dealing with the INK in which differs with the Basic2D Commands. Clearing Basic2D drawing commands needs the color value after the CLS. Thus, this example should work with CLS 0 or CLS rgb(0,0,0), but doesn't for me either... I have a NVidia Card running with Vista 64bit.

Just thought I would throw the two different CLS command styles out there.

Even the Clear Camera View didn't work for me.

I vote for BUG.

EDIT: @ GG, ran your .exe too and it did not work for me.

GG's exe failed on mine (trail of squares). I am running Windows 7 home premium 32 bit, video card is NVidia 8500 GT.

So do I - but where's the bug? Is it in DBPro or nVidia? I'd bet on the former but not a lot. In a related thread (can't recall which now ) we noticed differences between ATI and nVidia cards in some situations. I know there are differences in how the two cards initialise certain data in shaders (and that has nothing to do with DBPro) but have no idea whether that's the problem here. The present problem does have an "initialisation" feel to it though - it's as if something is assumed to be initialised each sync when in fact it might not be. But I'm guessing, which is as much as I can safely do at this hour.

Actaully, Riidii says your example works on his NVidia machine. So that's just confusing. It could come down to being Nvidia Drivers, but to me... working with DirectX directly in the past, I know something like(NOTE: AS FOR EXAMPLE):
g_pd3dDevice->Clear( 0, NULL, D3DCLEAR_TARGET, D3DCOLOR_XRGB(0,0,255), 1.0f, 0L );

should be clearing anything DirectX related on the screen...

But, Lee probably is using the GDI to draw the 2D stuff over the DirectX screen, so mabie there's something in that... that is messed up.

I think this one comes down to Lee looking at his own code to figure out as it looked like you guys tried various work-arounds to try to get it to work in above posts. If he needs Nvidia/Ati users to help him test beta code for that specific problem, then we can help test his 'fix attempts'

But that's just what I thinks...

Edit: if it helps any... I'm still using dbpro version 7.4... 7.5 looks to scarey to try right now...

I'll just add my observations, haven't figured out what they mean. ATI Radeon 1950X, Win7 x64 and GG's shows the initial box. The original code works unless I start in a window that doesn't match the "set display mode" command, then I also see the initial box.

I've attached a small plug-in purely for testing purposes that patches the CLS command in the Basic2D plug-in - the one that requires a colour value.

It has two commands in:
PATCH CLS <version> - where version is either 0 or 1
UNPATCH CLS

Pop the file into the plugins-user folder and try the patch with a value of 0 first to see if that fixes anything. If not, try it with a version of 2 instead. Calling the unpatch command before exiting will give you the best chance of your process shutting down correctly 0 you may need to kill it with task manager (I'm not going to spend any time fixing this bug because this isn't a fix-patch).

Anyway, if someone could try it out and report if it works or not, and if it reports any errors that would be great.

Oh, delete it from your plugins-user folder when you're done with it.

Tried your Patch IanM, but regret no change. Didn't notice any variation between the versions either. I tried versions 0, 1 and 2. The screen still does not clear. No errors reported either.

Here's another version of the patch - it works in exactly the same way.

Here's the original posted code with a few changes to make the testing easier:


If this doesn't show anything then I'm all out of ideas.

Hi IanM. Just tested the latest patch version but regret to say that there was no difference, it still doesn't clear screen. I'm sure everyone appreciates the amount of effort you have put in but it must be virtually imposible for you to sort the problem if you can't actually see it. Have Lee or Rick encountered it?

Ditto here. No change I'm afraid.

It looks like it's something to do with recent nVidia GFX cards and/or Vista/W7 - but the evidence isn't 100% clear. Here's some results using my exe gleaned from previous posts (I'll update this post when I get more results):

Fail:

nVidia GeForce GTX 285/Vista Home Premium 64 bit (GG)
nVidia GeForce GTX 260/W7 (Juney)
nVidia GeForce 8500 GT/Windows 7 home premium 32 bit (Jeff Miller)
Nvidia 9800 GX2/Vista 64 bit (Todd Riggins)
Geforce 9500GT/Vista basic (French Gui)
Unknown GFX card/Vista 32 bit (rolo99)
nVidia GeForce 8600 GTS/Windows 7 Professional x64 (Jeff032)
nVidia GeForce 8600 GTS/Windows Vista Home 32 bit (Jeff032)
Geforce 9500 GT/XP (Grog Grueslayer - first, and so far only, failure on XP)

Works:

ATI HD 3600/W7 64 bit (Adrian)
ATI Radeon 1950X/W7 64 bit (I think cjb2006 meant it works )
NVidia GeForce 8500 GT/Vista 64 bit (RiiDii)
ATI Radeon HD 3450/Vista Home Premium 32 bit (Globbits)
Mobile Intel(R) 4 Series Express Chipset/Vista 32 bit : Works (Mobiius)
nVidia GeForce G100/Vista 64 bit : Works (Grog Grueslayer)
Nvidia GeForce 7150M/nForce 630M/Laptop, Vista Home Premium edition 32 bit (Digger412)
Intel 82865G Graphics Controller/Desktop, XP Home edition (Digger412)
ATI Mobility Radeon Xpress 200/XP Home Edition (GG)
nVidia GeForce 6150 LE/Windows XP Media Center 32 bit (Jeff032)
Intel(R) 82845G/GL/GE/PE/GV Graphics Controller/Windows XP Home 32 bit (Jeff032)
NVidia GeForce 6200/XP 32 bit (Globbits)

No failures have been reported using XP or ATI cards (we now have a failure on XP reported using related code). Can anyone add more results to this? (And could those who posted incomplete specs give us more details, please?)

So far it seems RiiDii's machine is special. [Edit: Not any more. ]

Edit2: We now have a failure reported on an XP machine - but using a recent nVidia card again and somewhat different code (see below). Still no failures using ATI cards.

Grog Grueslayer has posted the following very simple code which works on some machines but not others:

It fails for me on a nVidia GeForce 8600 GTS / Windows 7 Professional x64. In several hours I'll have access to 3 more machines I could (hopefully) test it on, two are running XP and one is running Vista, as far as I know.

@GG - It works on my machine (temp2.exe). Comp specs:
Laptop, Vista Home Premium edition 32 bit
AMD Athlon 64 X2 Dual Core processor TK-55
Nvidia GeForce 7150M/nForce 630M (stock...*sniff*)

I'll try it on my old Gateway XP desktop and edit the results in soon.

EDIT: It works on my desktop too:
Desktop, XP Home edition
Intel Pentium 4 processor
Intel 82865G Graphics Controller (stock too...*sniff*..I know what I want for Christmas now =P)

The video card on the computer I used is a nVidia GeForce G100.

Thanks. Seems I'm having eyesight problems again.

Updated results in earlier post. Still seems to be much the same story:

No problems with XP or non-nVidia cards.
Problems with some newer nVidia cards and W7/Vista.

I wish I could see what the common factor is. This sort of problem is often dismissed as a driver issue - but how that helps us I don't know. I updated mine soon after getting the machine in May. Perhaps I should check for a more recent update?

GG,

My GPU for the Vista PC is ATI Radeon HD 3450

Have also tried it on XP 32 bit, NVidia GeForce 6200. Works fine on that too.

I just got CLS to not work on my computer at home that's an XP with a Geforce 9500 GT. Using CLS by itself doesn't work but with 0 it does work.

Here's the simple code (attached screenshot):

Thanks for that very simple example.

I think I'll send that to Lee to see what he thinks. It should be simple enough for him to see where things might be going wrong on some systems, even if he can't reproduce it himself.

For the record, your snippet works on my XP/non-nVidia laptop but fails on my Vista/nVidia PC.

I'll update the earlier post with the latest info shortly.
