Hi all,

I purchased DB Pro some time ago now, but never really got into it, due to real world issues taking precedence.

I've returned to trying to learn the language now, but I seem to be experiencing some really frustrating problems...

basically, pretty much anything I try to compile and run, doesn't work- but it seems to be only certain things that cause a problem...

for example, if I type



then that works without problems... if I try this, however



then the compiler seems to run, but nothing happens... the program just crashes.

I seem to get the same problem with the included examples too... if I run the "room demo" directly from the exe, it runs ok, but when I load the source code into the editor and try compiling and running it from there, the same thing happens- the compiler runs and then it just crashes. I'm not getting any error messages, so I have no idea what the problem could be.

I've also had problems running the CSMImport dll example... I just get a black screen with the mouse pointer showing, and the Advanced Terrain example... again, I just get a black screen.

When I first started using DB Pro (several months ago now) I wrote a very simple database program, which works fine, whether I run it from the editor, or directly from the exe... I'm very confused

I've tried re-installing DB, and updating it to version 5.5, but nothing seems to make any difference.

Sorry for the long post, but I'm really frustrated... I don't recall having these problems when I first used the software. Has anyone got any theories as to the problem? Am I doing something really stupid?

DBPro, Windows XP, P4 512m RAM, Radeon 9000

see if this works:

sync on

do
a=screen fps()
set cursor 0,0
print a
sync
if controlkey()=1 then end
loop

Turn on the 3d backdrop, move a=screen fps() into your loop,
and take the wait key out.

You don't want to have to press a key before the loop is executed, and the backdrop will ensure your printing won't overwrite itself.

backdrop on

sync on

do

a=screen fps()

set cursor 0,0

print a


sync

Thanks for the quick responses...

I've tried what both of you suggested, but I still get the same problem... the code I put up was only really to show the nature of the problem I'm getting, it's not important in itself... the first example compiles and runs without a problem, and displays "5" on the screen, but the second example seems to compile (the compile progress bar shows etc) but then nothing happens, no error messages, nothing... it just stops responding.

If it's because the code is wrong, then that's understandable, but like I said, I'm getting the same problem with the included example games... I ran "room demo" by double clicking the exe and it worked ok, I then loaded the source code into the editor and tried to compile and run it from there, and it crashed... I now can't run the exe directly either (I guess because the original has been overwritten with exe created when I compiled it)

I'm sorry, I can't explain the problem very clearly really.

I believe so...

I'm using DB Pro v 1.055 and IDE version 1.0.9.2

I'm sure I didn't have these problems when I first started using DB (several months ago) so I'm wondering if it's more to do with my system, rather than the software itself, but I'm not sure what might be causing it

I've just noticed that I can run things in step through mode... the debugger window appears and I am able to step through the code one line at a time, but the actual window the program itself runs in doesn't appear... I just don't understand what's going on.

run dxdiag, check for the latest driver updates for your videocard, re-install pro and do the updates (fixed a problem on my system), from the sound of it something does not like the updated DB, try running the examples after an install and see if they work with 1.01, then upgrade and check again, oh! just rememberd, as of 5.4/5 you MUST have dx9.0b, thats 9.0B<<that B is important, that could explain why the older .exe`s work but the updated ones don`t, if all else fails then try mailing TGM direct, they are normaly happy to help as long as you are not being a pain (I would strongly suggest you check if you have DX9.0b first).

According to dxdiag there are no problems anywhere, and DX9b is installed (I reinstalled that too, just to be sure!) but I'm still having problems.

I've emailed TGC Support now, so hopefully they'll be able to tell me what I'm doing wrong, until they respond I shall just continue to bang my head against the wall........

Thanks for your help anyway, CattleRustler, JerBil, Zokomoko and Mentor!
