在编写对话框程序时，希望能在按钮控件里显示一个小插图,如图所示

最初使用的方法是使用 BM\_SETIMAGE 消息，但却不能达到满意的效果，在网上查了一通资料，最后终于实现了，现在把实现的方法记下来。

首先来到MSDN上，查得如下资料

# BM\_SETIMAGE message #

Associates a new image (icon or bitmap) with the button.

## Parameters ##

*wParam*

The type of image to associate with the button. This parameter can be one of the following values:

*  IMAGE\_BITMAP
 *  IMAGE\_ICON

*lParam*

A handle (**HICON** or **HBITMAP**) to the image to associate with the button.

## Return value ##

不重要，略

## Remarks ##

The appearance of text, an icon, or both on a button control depends on the **BS\_ICON** and** BS\_BITMAP** styles, and whether the **BM\_SETIMAGE** message is called. The possible results are as follows:

<table> 
 <tbody> 
  <tr> 
   <th>BS_ICON or BS_BITMAP Set?</th> 
   <th>BM_SETIMAGE Called?</th> 
   <th>Result</th> 
  </tr> 
  <tr> 
   <td>Yes</td> 
   <td>Yes</td> 
   <td>Show icon only.</td> 
  </tr> 
  <tr> 
   <td><span style="color:#3399ea;">No</span></td> 
   <td><span style="color:#3399ea;">Yes</span></td> 
   <td><span style="color:#3399ea;">Show icon and text.</span></td> 
  </tr> 
  <tr> 
   <td>Yes</td> 
   <td>No</td> 
   <td>Show text only.</td> 
  </tr> 
  <tr> 
   <td>No</td> 
   <td>No</td> 
   <td>Show text only</td> 
  </tr> 
 </tbody> 
</table>

既然希望同时显示图片和文字，那么就应该采取上表中的第二行设置（蓝色）。

故控件属性设置为：

![SouthEast 1][]

然后在 OnInitDialog() 函数中添加如下语句：

SendDlgItemMessage(hwnd,IDC_BUTTON1,BM_SETIMAGE,IMAGE_BITMAP,(LPARAM)LoadBitmap(hIn,MAKEINTRESOURCE(IDB_BITMAP1)));

但是效果却是这样的：

![SouthEast 2][]

如果把控件属性中的Bitmap项改为 True ，效果又成了这个样子：

![SouthEast 3][]

真的很让人抓狂。在一通搜索后，发现解决方案就在MSDN中。在BM\_SETIMAGE词条的下面，有一条老外的评论，是这样的：

## Community Additions ##

## Icon with text solution ##

I had the same problem for the icon + text in the button and I solved using the version 6 of the common controls.  
You can make this by adding the library (if I understand it, I'm not sure).  
  
However I've added it with the preprocessor directive:

\#pragma comment(linker,"\\"/manifestdependency:type='win32' name='Microsoft.Windows.Common-Controls' version='6.0.0.0' processorArchitecture='X86' publicKeyToken='6595b64144ccf1df' language='\*'\\"")  
  
"EDIT:" This preprocessor directive go on a single line, I don't know why It force me to put a line break after "\#pragma"

也就是说，使用6.0.0.0版本的 Common-Controls 就好了，所以在程序里加上这么一句话：

#pragma comment(linker,"\"/manifestdependency:type='win32' name='Microsoft.Windows.Common-Controls' version='6.0.0.0' processorArchitecture='X86' publicKeyToken='6595b64144ccf1df' language='*'\"")

就万事OK了（64位平台，改为AMD64)
