C++控制台程序，原语句loadimage(&fm, "./fire/flower.jpg", 3120, 240);现已将flower.jpg转化为bmp文件导入到resource资源中,值为IDB_BITMAP1 改写成loadimage(&fm, LPCTSTR(IDB_BITMAP1), 3120, 240);程序出错，异常中断，求助该如何写？谢谢！！

楼主，我用loadimage(&fm, RT_BITMAP, MAKEINTRESOURCE(IDB_BITMAP2));
也出现了这种情况，请问一下你最后是怎么解决的？

之前已经说清楚了，用文本打开 rc 文件，如果其中的代码是： RT_BITMAP IDB_BITMAP2 "xxx.bmp" 且 resource.h 中，有 IDB_BITMAP2 的宏定义： #define IDB_BITMAP2 1000 并且 xxx,bmp 的确是一个 bmp 文件的话，是可以的，不能只是个 bmp 扩展名的假 bmp。凡是 resource.h 中没有定义的宏，VS 编辑器中，类型和名字都被加上了引号。如 "RT_IMAGE"，"IDB_BITMAP2"。 MAKEINTRESOURCE(IDB_BITMAP2) 的作用和 (LPCTSTR)IDB_BITMAP2 一样。如果没有定义，就要用 TEXT("IDB_BITMAP2") 这样的字符串。自己排查一下，是否参数使用的问题，如 TEXT("IDB_BITMAP2") 和 (LPCTSTR)IDB_BITMAP2 的区别。不用按我的来，而是应该按你的实际情况来定，搞清楚资源 id、资源名 id 是数字 (宏定义) 还是字符串。

改成是上面的了，虽然程序编译不报错了，但是装载在资源中的图片运行时也不显示了，原因何在？

你用的是 easyX loadimage 而不是 Windows API LoadImage。网上查阅，easyX 的 loadimage 有以下重载：

void loadimage(
	IMAGE *lpDestImage,
	LPCTSTR lpImageFile,
	int nWidth = 0,
	int nHeight = 0,
	bool bResize = false
);

void loadimage(
	IMAGE *lpDestImage,
	LPCTSTR lpResType,
	LPCTSTR lpResName,
	int nWidth = 0,
	int nHeight = 0,
	bool bResize = false
);

所以，格式不需要转换，即使转换了，也没法通过 Windows 的 LoadImage 得到 easyX 的 IMAGE 对象。正确的做法是：

loadimage(&fm, MAKEINTRESOURCE(RT_IMAGE), MAKEINTRESOURCE(IDB_BMP1));

这里的 RT_IMAGE 和 IDB_BMP1 由你的资源类型和名字决定。如果你确定添加的是 bmp 资源，则格式如下：

loadimage(&fm, RT_BITMAP, MAKEINTRESOURCE(IDB_BMP1));

RT_BITMAP 是 Windows 已定义的资源类型。如果是其他的系统资源类型，都是 RT_ 开头的。如果是自定义的类型，在头文件定义为数值，如 #define RT_IMAGE 100，代码中就是 MAKEINTRESOURCE(RT_IMAGE)，没有定义宏的，都被认为是字符串，则传 TEXT("RT_IMAGE") 即可。

LoadImage The LoadImage function loads an icon, cursor, or bitmap. HANDLE LoadImage( HINSTANCE hinst, // handle of the instance containing the image LPCTSTR lpszName, // name or identifier of image UINT uType, // type of image int cxDesired, // desired width int cyDesired, // desired height UINT fuLoad // load flags ); Parameters hinst Handle to an instance of the module that contains the image to be loaded. To load an OEM image, set this parameter to zero. lpszName Handle to the image to load. If the hinst parameter is non-NULL and the fuLoad parameter does not include LR_LOADFROMFILE, lpszName is a pointer to a null-terminated string that contains the name of the image resource in the hinst module. If hinst is NULL and LR_LOADFROMFILE is not specified, the low-order word of this parameter must be the identifier of the OEM image to load. The OEM image identifiers are defined in WINUSER.H and have the following prefixes: Prefix Meaning OBM_ OEM bitmaps OIC_ OEM icons OCR_ OEM cursors If the fuLoad parameter includes the LR_LOADFROMFILE value, lpszName is the name of the file that contains the image. uType Specifies the type of image to be loaded. This parameter can be one of the following values: Value Meaning IMAGE_BITMAP Loads a bitmap. IMAGE_CURSOR Loads a cursor. IMAGE_ICON Loads an icon. cxDesired Specifies the width, in pixels, of the icon or cursor. If this parameter is zero and the fuLoad parameter is LR_DEFAULTSIZE, the function uses the SM_CXICON or SM_CXCURSOR system metric value to set the width. If this parameter is zero and LR_DEFAULTSIZE is not used, the function uses the actual resource width. cyDesired Specifies the height, in pixels, of the icon or cursor. If this parameter is zero and the fuLoad parameter is LR_DEFAULTSIZE, the function uses the SM_CYICON or SM_CYCURSOR system metric value to set the height. If this parameter is zero and LR_DEFAULTSIZE is not used, the function uses the actual resource height. fuLoad Specifies a combination of the following values: Value Meaning LR_DEFAULTCOLOR The default flag; it does nothing. All it means is "not LR_MONOCHROME". LR_CREATEDIBSECTION When the uType parameter specifies IMAGE_BITMAP, causes the function to return a DIB section bitmap rather than a compatible bitmap. This flag is useful for loading a bitmap without mapping it to the colors of the display device. LR_DEFAULTSIZE Uses the width or height specified by the system metric values for cursors or icons, if the cxDesired or cyDesired values are set to zero. If this flag is not specified and cxDesired and cyDesired are set to zero, the function uses the actual resource size. If the resource contains multiple images, the function uses the size of the first image. LR_LOADFROMFILE Loads the image from the file specified by the lpszName parameter. If this flag is not specified, lpszName is the name of the resource. LR_LOADMAP3DCOLORS Searches the color table for the image and replaces the following shades of gray with the corresponding 3D color: Color Replaced with Dk Gray, RGB(128,128,128) COLOR_3DSHADOW Gray, RGB(192,192,192) COLOR_3DFACE Lt Gray, RGB(223,223,223) COLOR_3DLIGHT LR_LOADTRANSPARENT Retrieves the color value of the first pixel in the image and replaces the corresponding entry in the color table with the default window color (COLOR_WINDOW). All pixels in the image that use that entry become the default window color. This value applies only to images that have corresponding color tables. If fuLoad includes both the LR_LOADTRANSPARENT and LR_LOADMAP3DCOLORS values, LRLOADTRANSPARENT takes precedence. However, the color table entry is replaced with COLOR_3DFACE rather than COLOR_WINDOW. LR_MONOCHROME Loads the image in black and white. LR_SHARED Shares the image handle if the image is loaded multiple times. If LR_SHARED is not set, a second call to LoadImage for the same resource will load the image again and return a different handle. Do not use LR_SHARED for images that have non-standard sizes, that may change after loading, or that are loaded from a file. Windows 95 and Windows 98: The function finds the first image with the requested resource name in the cache, regardless of the size requested. LR_VGACOLOR Uses true VGA colors. Return Values If the function succeeds, the return value is the handle of the newly loaded image. If the function fails, the return value is NULL. To get extended error information, callGetLastError. Remarks When you are finished using the bitmap, cursor, or icon, you can release its associated memory by calling one of the functions in the following table. Resource Release function Bitmap DeleteObject Cursor DestroyCursor Icon DestroyIcon The system automatically deletes these resources when the process that created them terminates, however, calling the appropriate function saves memory and decreases the size of the process's working set. Windows CE: The cxDesired and cyDesired parameters must be zero for IMAGE_BITMAP. Windows CE does not support stretching and shrinking of icons. The fuLoad parameter must be zero (==LR_DEFAULTCOLOR). If you are targeting a platform that does not support mouse cursors, you cannot specify the SM_CXCURSOR and SM_CYCURSOR values in the cxDesired and cyDesired parameters, and you cannot specify IMAGE_CURSOR for the uType parameter. If you are targeting a platform that supports mouse cursors, you can specify SM_CXCURSOR and SM_CYCURSOR in the cxDesired and cyDesired parameters, and IMAGE_CURSOR in the uType parameter.
