一般情况下，我们是用不带边框的对话框来充当Tab Control的每个选项卡的内容的。
例如，主对话框IDD_TABBOX上有一个Tab Control，上面有两个选项卡，第一个选项卡用的是IDD_DIALOG1充当内容，第二个用的则是IDD_DIALOG2。IDD_DIALOG1和IDD_DIALOG2的Border属性设为None，Style属性设为Child，如下三张图所示。
但是用对话框充当选项卡内容会有烦人的深色对话框背景，和选项卡的样式并不搭，看起来也不好看，如下图所示。
其实，要去掉这个深色对话框背景很简单，只需要在每个选项卡的对话框的消息处理函数的WM_INITDIALOG里面加一句EnableThemeDialogTexture(hdlg, ETDT_ENABLETAB);就行了。有多少个选项卡，就加多少句这句话。
使用EnableThemeDialogTexture函数前，需要包含头文件Uxtheme.h和库文件Uxtheme.lib。该函数支持Windows XP系统。
#include <Uxtheme.h>
#pragma comment(lib, "Uxtheme.lib")
注意：使用这个函数后，如果程序处理了Static控件的WM_CTLCOLORSTATIC消息，直接return 0就可以用渐变背景了。不需要返回HBRUSH背景刷，SetTextColor设置的文字颜色就能生效。
运行之后是这样的：
深色的对话框背景就成功去除掉了。话说XP系统的选项卡界面真的挺好看的，是一个渐变色。
