I'm trying to use cheat engines debugger to step through some code. The code on question is a dll I'm injecting into a game. I want to confirm things.

I'm using the VEH debugger because at the same time I'm debugging with visual studio so the Windows debugger isn't available.

My question is, after setting a break point, why is the step through functions greyed out? I loaded the debugging tool bar, and even in the drop down window they aren't available. Why is this?

Did the breakpoint trigger, or did you only set it?

You really shouldn't have more than one debugger attached to a program at once.

Code:
pDeviceContextVTable = (DWORD_PTR*)pContext;
    pDeviceContextVTable = (DWORD_PTR*)pDeviceContextVTable[0];
    ogCreateInputLayout = (fnCreateInputLayout)pDeviceContextVTable[29];


So the reason Im using a VS debugger is because I need to get the EIP from a specific function call. I'm using a vtable look up to get a DirectX function address. To do so, I put a VS breakpoint on the function call (last line in code above). When execution stops on that line, I Grab the EIP from VS, and before pushing continue in VS to resume runtime, I Go to Cheat Engine and goto the address in the EIP. I then set a CE breakpoint on that address, hit continue in VS and then step through in CE to see if it steps into the D3D function.

This is so I can confirm I'm getting the correct function. But like I said, at that point, there is no way for me to step through...not that I can see anyway.

Ok, so it was due to me not detaching the VS debugger. Once I did that cheat engines step through functions where available.
