Well... I think I'm not the first to ask this question, but I haven't find any thread ;
Is it possible to detect in DBP which version of DirectX is running on the system ?
Thank's !

I think that DBPro programs will only run on 9.0c, so it's pretty easy!

That's not exactly my question ... in this way : how to detect the 9.0c version is installed ?

My actual solution is to scan the logfile in \Windows\Directx.log



And I'd like to use something more... efficient

Not 100% right anyway

My logic was - given that DBPro programs will only run with 9.0c installed, detecting inside DBPro apps will only return 9.0c?

Yes, you're right, but all I want to do is to display a warning message to users who don't own the correct version of DirectX.

Just because I think that 50% of users don't even know exactly what version of DirectX they use... Last night I thought I was using 9.Oc DirectX until I try a game trial and realize I was running 9.0b

or in other words, if you have DX8.1 then your Darkbasic app will not run, hence it can`t find out you do have 8.1, since it only will run if you have 9.0c, you need to make an application in some other compiled language that will check for directx and install 9.0c if it isn`t there, then go on to run or install your Darkbasic application for you, most installer software should be able to check for this.



the average IQ is 100...but the people that took the test where trying to look smart. most people don`t go over 50.

I think the DBPro app bails out with an error like "can't find d3d9.dll" befor eit even runs, hence the only way your checking code will run is it if has 9.0c

As Me! says its best to use another language to find the version, which would then execute the dbpro app if 9.0c is there.

Ok, that's clear, thank's to both of you! I want to keep a single standalone exe file (so no C++ launcher or installer) but at least I'll keep my \Windows\Directx.log scan check for the 9.0B situation...
