why does this crash??:
cObject is probably null. You need to tell us more, though - for example, the type of crash (I predict access violation).

ok, here are the source (I modifyed the code a little, but I get the same error at the same place in the code), and yes superpig, it is access violation lol :)

well, I have been debuging *alot*.. but still, this stupid ass error wont go away:) none of the pointers are missing an adress and the filename is ok, but when I run it I get a memory could not be "read" error??
Im not even able to get the error message from the D3DXCreateTextureFromFile function because the it crashes before any message is caught..

So you're telling me the DirectX debug runtime doesn't give you any error messages leading up to the crash?
I'd recommend you add the following couple of lines of code before the call to D3DXCreateTextureFromFile:
You also need to be sure you're initialising these variables - g_pd3dDevice, cASEFile and the like - to zero at startup.
I'd recommend you add the following couple of lines of code before the call to D3DXCreateTextureFromFile:
assert(g_pd3dDevice, "g_pd3dDevice is NULL when I try calling the function!");assert(cASEFile, "cASEFile is NULL when I try calling the function!");assert(this, "I'm an invalid object!");You also need to be sure you're initialising these variables - g_pd3dDevice, cASEFile and the like - to zero at startup.

I added the colde just above where the crash occurs, but I still get the same f... error.. do you feel me now??:) hehehe
Breakpoint just above the call to D3DXCreateTextureFromFile on the last executable line that was run, then look at the values of everything you are passing into the function. You will find out what's wrong if you do this.

If I told you that I also did that, would you even believe me?? hehehe :) I have to say that OpenGL is rocking the ass of DX..
