I am trying to turn my current C++ easy game to a bitmap game using
DirectX SDK august 2009. I get everything to come out good but I have
1 error and I can't figure it out. I was told to come here for help. I
will post the error. Also not that I put in #pragma comment (lib,
"d3d9.lib"). so I got rid of one of 2 erros now I am just left with
this:

error LNK2019: unresolved external symbol _D3DXLoadSurfaceFromFileA(a)32
referenced in function "int __cdecl Game_Init(struct HWND__ *)" (?
Game_Init@@YAHPAUHWND__@@@Z)

I don't like #pragmas to pull in libraries. Instead, I prefer to
explicitly list them on the linker's set of input libraries. I
recommend you look at an existing DirectX sample app, and copy its
list of input libraries. For reference, a program I've written has
these entries as part of its linker inputs:

Debug:
d3dxof.lib dxguid.lib d3dx9d.lib d3d9.lib DxErr.lib
Release:
d3dxof.lib dxguid.lib d3dx9.lib d3d9.lib DxErr.lib

I am very new to DirectX SDK so I don't know what you mean by

like how do I put that into my program? or how do I fix this error I
am getting without using the #pragmas? This a for fun program and my
second thing I have made with the SDK so it is still very new to me.

Look up the function in MSDN. It tells you on that page that you need
library file d3dx9.lib.

To link in a lib file you can either use the #pragma, or you can type
in the name of the lib in the settings:
Menu: Project, Properties, Linker, Input, Additional Dependencies =
d2dx9.lib
