I know that i need to put handle of module as one of parameters and i did it but it's not a handle where a window is. Is it ok?
For software mode you're supposed to provide a handle to a DLL that implements a D3D11 driver + rasterizer in software. If you don't have one, you can't use it.
So as i understand correctly i need to provide a handle of my main application but not a handle of dll where my engine is?
I do such thing - GetModuleHandle("MayApp.vcshost.exe"); and this function retuns handle which isn't null but i again have error - "Incorrect parameter" in the function D3D11CreateDivice. What's wrong?
The handle is expected to be that of a native module (commonly a dll), which implements and exports the D3D driver entrypoints (there are lot of them).
You asked about your incorrect use of the handle parameter... MJP told you that this parameter is supposed to be used to load a custom D3D Driver DLL (and tried to steer you away from this and onto the WARP software driver)... You ignored him and kept trying to pass a handle to your application as if it were a software D3D driver... Nik02 again explained that the handle is for a driver DLL, and if you want to use it, you must implement this DLL yourself... and then you treat his reply as a joke, and tell him what they both told you already?? I dont understand how you're simultaneously understanding their advice and ignoring their advice!
Very funny Nik02. I need to implement a software driver for that.
You can either
* load a software driver DLL (which you can write yourself, in theory...),
* use WARP with it's feature level restrictions, or
* use the reference device, although it's supposed to only be used for debugging purposes.
