    Okay. Yes, I see it. DXSETUP.exe

    Installed with no problems.

    I'll go ahead and try to run my proggie and see what happens.

    And here are my errors,

    Could this be because I didn't install the symbol files?

    No that is b/c you aren't linking with the export libraries.

    You will need to add these lines for your linker.

    d3d9.lib
    d3dx9.lib (release) or d3dx9d.lib (debug)
    dxguid.lib (this has all the GUIDs for the interfaces)

    For MSVC you add those lines in Linker->Input->Additional Dependencies

    Direct3DCreate9() is in d3d9.lib
    All the other unresolved externals you are getting are in d3dx9.lib and d3dx9d.lib

    If you are linking with the debug version of D3DX (d3dx9d.lib) you should also define D3D_DEBUG_INFO in your pre-processor settings. Additionally you will want to run dxcpl.exe (Program Files->Microsoft DirectX SDK (month year)->DirectX Utilities->DirectX Control Panel) and set the Debug output level to about halfway for Direct3D, DirectInput, and DirectSound (if you use the last two). This will give you some valuable debugging information when developing your Direct3D application. Also you will want to set each of them to use the Debug version of their DLLs. Note that before running any retail game you will want to set these back to retail versions or your game will run like garbage. For other debugging you may want to use maximum validation, break on memory leaks, etc. Break on memory leaks is valid b/c if you set this the DirectX runtimes will break on a COM resource leak. Also when Direct3D exits and if your debug output level is high enough you will get resource allocation IDs for each allocation. If you set the control panel to break on memory leaks and type the allocation ID in the Alloc ID text field your application will break on the line of code that is allocating a resource that has the ID. Very helpful for finding memory leaks.

    Keep in mind that Direct3D is a hard beast to debug b/c if you leak ANY resource along the way the entire device will leak and dump tons of leaks to std::out even though it may have been caused by one leak.

    I did as you suggested. I'm using MSVS 2010 Express and I placed those files in additional dependencies each on it's own line. It returned one error.

    1>LINK : fatal error LNK1104: cannot open file 'd3dx9.lib'


    BTW, here is my code if it helps. It's from an online DX tutorial: just a simple program to display a rotating triangle.

    Code:
    // include the basic windows header files and the Direct3D header file
    #include <windows.h>
    #include <windowsx.h>
    #include <d3d9.h>
    #include <d3dx9.h>
    
    //#pragma comment (lib, "d3d9.lib")  // D3D library
    //#pragma comment (lib, "d3dx9.lib") // D3DX library
    
    // define the screen resolution
    #define SCREEN_WIDTH 800
    #define SCREEN_HEIGHT 600
    
    // include the Direct3D Library files
    //#pragma comment (lib, "d3d9.lib")
    //#pragma comment (lib, "d3dx9.lib")
    
    // global declarations
    LPDIRECT3D9 d3d;    // the pointer to our Direct3D interface
    LPDIRECT3DDEVICE9 d3ddev;    // the pointer to the device class
    LPDIRECT3DVERTEXBUFFER9 v_buffer = NULL;    // the pointer to the vertex buffer
    
    // function prototypes
    void initD3D(HWND hWnd);    // sets up and initializes Direct3D
    void render_frame(void);    // renders a single frame
    void cleanD3D(void);    // closes Direct3D and releases memory
    void init_graphics(void);    // 3D declarations
    
    struct CUSTOMVERTEX {FLOAT X, Y, Z; DWORD COLOR;};
    #define CUSTOMFVF (D3DFVF_XYZ | D3DFVF_DIFFUSE)

        v_buffer->Lock(0, 0, (void**)&pVoid, 0);
        memcpy(pVoid, vertices, sizeof(vertices));
        v_buffer->Unlock();
    }
    The pragmas were suggested on another site I found while googling a solution. As you might guess, they didn't help, hence the comment out.

    neither d3dx9.lib nor d3dx9d.lib can be found

    I changed the order of those files you mentioned. Now it only tells me it can't find dxguid.lib. It stops at whatever the first file is.

    It did find d3d9.lib

    I did a search for both files. The difference is that this file is in
    C:\Program Files\Microsoft SDKs\Windows\v7.0A\Lib
    while d3dx9.lib is not. Apparently this is the directory it wants the includes to be in. I'm going to copy that file here and see what happens.

    Don't copy the file... Then you just end up with junk everywhere. Just add the file with complete path, or add the folder to the solution so it knows to look there.

    SUCCESS

    I moved both files into that directory and it worked without errors. Now hopefully I won't have to pester you guys for a while.

    Sry, syz, I did it before I saw your post. Should I take them out?

    Add the complete path to linker->additional dependencies?

    Where in the solution would I add the folder?

    I would remove any files you copied because they should not be in those folders. That is not the proper method.

    Try adding the paths to where those files are originally located in Linker->General->Additional Library Dependencies

    I don't see "additional library dependencies"

    I do see "additional library directories" is this what you meant?

    I put a directory where both files can be found:

    C:\Program Files\Microsoft DirectX SDK (June 2010)\Lib\x86

    here are my errors

    Are you sure I can't just copy them into the standard directory?

    Yes, I meant "Additional Library Directories." I was reading your comment while typing and messed up.

    You can do it however you want, but that is not the right way to do things.

    Do you still have the files listed inside Linker->Input->Additional Dependencies? You need them there also.

    No, I took them out thinking they'd be redundant but I'll go ahead and add them and see what happens.
