近來需要想學習一下opengl，但是小白沒有任何基礎，也非計算機專業出身，只能一步一步學習nehe的程式來學習了。這裡實現了在WIN10 vs2013 opengl2.0 環境下跑通nehe教程第一課的程式。

1.系統配置

新建vs2013 “win32專案” 工程

由於我把lib .h 和dll檔案放在一個目錄下了
屬性->vc++目錄->包含目錄中新增D:\software_install\opengl
屬性->vc++目錄->庫目錄中新增D:\software_install\opengl
屬性->連結器->輸入->附加依賴項中新增
glew32.lib
glew32mx.lib
glew32mxs.lib
GLAUX.LIB
glew32s.lib

系統環境變數Path 增加 D:\software_install\opengl

2.視窗建立程式

1：LPCWSTR 和 char*

需要把程式碼裡面的char* 型別轉換為 LPCWSTR型別。這類用TEXT 講char* 型轉化為LPCWSTR。

if (!RegisterClass(&wc))                                    // Attempt To Register The Window Class
    {
        MessageBox(NULL, TEXT("Failed To Register The Window Class."
 
), TEXT("ERROR"), MB_OK | MB_ICONEXCLAMATION);
        return FALSE;                                           // Return FALSE
    }

採用MultiByteToWideChar 進行轉化，把char* filename轉為wszClaasName

AUX_RGBImageRec *LoadBMP(char* Filename)                    // 載入點陣圖圖象
{
    FILE *File = NULL;                          // 檔案控制代碼
 

    if (!Filename)                              // 確保檔名已提供
    {
        return NULL;                            // 如果沒提供，返回 NULL
    }
    fopen_s(&File, Filename, "r");                      // 嘗試開啟檔案

    WCHAR wszClassName[256];
    memset(wszClassName, 0, sizeof(wszClassName));
    MultiByteToWideChar(CP_ACP, 0, Filename, strlen(Filename) + 1, wszClassName, sizeof(wszClassName) / sizeof(wszClassName[0]));

    if (File)                               // 檔案存在麼?
    {
        fclose(File);                           // 關閉控制代碼
        return auxDIBImageLoad(wszClassName);               // 載入點陣圖並返回指標
    }
    return NULL;                                // 如果載入失敗，返回 NULL
}

結果
