Did you actually read the error message? And look at the code?
*** Source Snippet Removed ***
groundMap is an array of int's, and pSurface is a IDirect3DSurface9*. You can't assign one to the other, which is what the error tells you.

We can't tell you why you wrote the code that you did. You should know that. Unless of course you've copied this code in from some other place without understanding it, in which case you should probably go back to the source and have them explain it to you.

See the documentation for IDirect3DDevice9::StretchRect. This function works by copying an image from one IDirect3DSurface9 to another. This is not just a type, but a D3D object, containing an image buffer. Your array is not an image buffer, it's an array of numbers.
From the rest of you code I assume you want that number to specify one of your textures, and you want to draw that texture. To do that you would use something like the following:
*** Source Snippet Removed ***

And that should give you another error, if the code you posted is your actual code, as you don't define destRect before using it. You need to set the destination rectangle to the appropriate place the texture should be drawn.

Note to the rest: This is a very helpful reply, learn from him! He didn't fix my code but pointed me in the direction so I can learn.

You need to change your code so that you are not trying to use an integer as a surface. You cannot convert an integer into a surface using any sort of cast. An integer is not a surface. It is a number.
