Here a group of us will go through the tutorial and ask questions. Hope this doesn't annoy anyone.

me too hehe, well here is for the first question,

why does this not work?

#include <windows.h>int APIENTRY WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow) {  // The main loop.  This will call Game_Main() repeatedly, stopping// only to process Windows messages, and terminating with WM_QUIT.while(TRUE){    // Grab any Windows messages that are for us    if (PeekMessage(&msg, NULL, 0, 0, PM_REMOVE))    {        // Send these messages to WindowProc        if (msg.message == WM_QUIT)            break;        TranslateMessage(&msg);        DispatchMessage(&msg);    }    // Call our Game function    else if (G.bActive) Game_Main();}//////////////////////////////////////////////////////////////////////////////// WindowProc//// Whenever the operating system has a message for us, it ends up here.  If// we're interested in any particular message, we have to provide code to// handle it.//LRESULT CALLBACK WindowProc(HWND hWnd, UINT msg, WPARAM wParam, LPARAM lParam){    // Process the window message    switch (msg)    {        case WM_ACTIVATE:            // The active state of our window is changing (e.g. ALT-TAB).            // We keep track of this so that we don't bother drawing            // frames of animation if it can't be seen anyhow...            G.bActive = !((BOOL)HIWORD(wParam));            return 0L;        case WM_KEYDOWN:            if (wParam == VK_ESCAPE)            {                // The ESCAPE key quits...                G.bQuitting = TRUE;                PostQuitMessage(0);                return 0L;            }            break;        case WM_DESTROY:            // We're done; quit the main loop            PostQuitMessage(0);            return 0L;    }    // Pass all other messages on for default processing    return DefWindowProc(hWnd, msg, wParam, lParam);}}

you don't have all the files necessary and plus you're missing some variables as well.

you'll need to go into Tools, Compiler Options, and enter these as is:

-lwinmm -lddraw -ldxguid -ldinput -ldsound

then check add to linker options

also under directories you'll have to add the directx lib and directx include. they will be whereever you install the DXSDK.

try this [smile]
Go to Tools, Compiler Options, and...
(make sure you use the little folder button over "Delete Invalid", to browse for the folder)
