<br>主题：關于在ImageList中加入BMP
<br>内容：項目文件夾下面有一個BMP(24位)圖像。p1.bmp<BR>我在程序里面用：<BR>CImageList m_Image;<BR>m_Image.Create("p1.bmp",50,0,RGB(0,0,0));<BR>m_Image.Draw(pDC,CPoint(100,100),ILD_TRANSPARENT);時會出錯。<BR><BR>請高手指點原因。<BR>謝謝！

<br>内容：应该为：（运行结果如下图所示）<BR>CImageList m_Image;<BR>m_Image.Create(IDB_BITMAP_TEST, 400, 0, RGB(0,0,0));<BR>m_Image.Draw(pDC, 0, CPoint(100,100), ILD_TRANSPARENT);//4个参数

<br>内容：m_Image.Draw(pDC, 0, CPoint(100,100), ILD_TRANSPARENT);//4个参数<BR>是我抄錯。<BR><BR>我是要加載不是由VC制作的BITMAP。而是由其它軟件制作的BMP圖片，所以不能以IDB_BITMAP_TEST為參數。<BR><BR>

<br>内容：你是说打开一个bmp文件，而不是从exe文件加载位图吧！<BR>那你m_Image.Create("p1.bmp",50,0,RGB(0,0,0));可定错了，Create（）是直接从exe文件加载位图的，可别以为参数是"p1.bmp"就认为可加载位文件了，它跟ID(比如IDB_BITMAP_TEST)基本没区别的，请看下图：只是命名方式不一样而已哦！<BR>
