如何使用BS_ICON创建显示图标和文本的按钮并发送BM_SETIMAGE？ [英] How can I create button showing icon and text using BS_ICON and sending BM_SETIMAGE?
问题描述
大家好！
我想首先感谢所有花时间查看此主题并尝试提供帮助的人。
我需要制作一个主窗口的子按钮，具有以下特征：
- 它有蓝色背景;
- 我显示一个图标;
- 它在图标下显示文字;
- 文字应该是粗体;
- 文字是塞尔维亚语 - 西里尔语;
就文字而言，我知道有BS_BOTTOM风格可以在按钮底部显示它，有SetFont（）函数使其变粗，但我不知道如何让它接受西里尔字符（代码示例将不胜感激）。
As对于图标+文字部分，这是我到目前为止所尝试的：

在MSDN上，声明按钮显示图标和文字BS_BITMAP或BS_ICON不得设置，我应该发送BM_SETIMAGE。
我试过了，但它失败了。
我使用WIN32 API在MS Visual Studio Express 2008，Windows XP，C ++中工作。如果需要任何其他信息（源代码或类似的东西），请求它，我将非常乐意提供它。
以下代码对我有用，使用图标或位图：
HINSTANCE hInstance = GetModuleHandle（NULL）;
hButton = CreateWindowEx（ 0 ，L 按钮，L АБВГДЕЖЗ，WS_VISIBLE | WS_CHILD | BS_TEXT | BS_BOTTOM， 100 ， 100 ， 150 ， 150 ，hWnd，（HMENU） 4000 ，hInstance， 0 ）;
// 使用图标
HICON hIcon = LoadIcon（ hInstance，MAKEINTRESOURCE（IDR_MAINFRAME））;
SendMessage（hButton，BM_SETIMAGE，（WPARAM）IMAGE_ICON，（LPARAM）hIcon）;
// 或使用位图
HANDLE hBitmap = LoadImage （hInstance，MAKEINTRESOURCE（IDR_BUTTON），IMAGE_BITMAP， 0 ， 0 ，LR_DEFAULTCOLOR）;
SendMessage（hButton，BM_SETIMAGE，（WPARAM）IMAGE_BITMAP，（LPARAM）hBitmap）;
我有不尝试过西里尔字符，但我想你只需要在设置西里尔字体 CreateWindowEx 调用的第三个参数中发送它们>。
西里尔语也行得正常。

Hello everyone!
I would like to start by saying thanks to everyone who takes some time to view this thread and try to help.
I need to make a button that is a child of a main window with following characteristics:
- It has blue background;
- I displays an icon;
- It displays text under icon;
- Text should be bold;
- Text is in Serbian-Cyrillic;
As far as text is concerned, I know there is BS_BOTTOM style to display it at the bottom of the button, and there is SetFont() function to make it bold, but I don't know how to make it accept cyrillic characters ( code example would be greatly appreciated ).
As for icon + text part, this is what I have tried so far:

At MSDN, it is stated that in order for button to display icon and text BS_BITMAP or BS_ICON must not be set, and I should send BM_SETIMAGE.
I have tried that, but it failed.
I work in MS Visual Studio Express 2008, on Windows XP, in C++, using WIN32 API. If any other information is required ( source code or something similar ), please ask for it, I will more than gladly supply it.
The following code worked for me, using either an icon or a bitmap :
HINSTANCE hInstance = GetModuleHandle(NULL); hButton = CreateWindowEx(0, L"Button", L"АБВГДЕЖЗ", WS_VISIBLE | WS_CHILD | BS_TEXT | BS_BOTTOM, 100, 100, 150, 150, hWnd, (HMENU)4000, hInstance, 0); // use an icon HICON hIcon = LoadIcon(hInstance, MAKEINTRESOURCE(IDR_MAINFRAME)); SendMessage(hButton, BM_SETIMAGE, (WPARAM)IMAGE_ICON, (LPARAM)hIcon); // or use a bitmap HANDLE hBitmap = LoadImage(hInstance, MAKEINTRESOURCE(IDR_BUTTON), IMAGE_BITMAP, 0, 0, LR_DEFAULTCOLOR); SendMessage(hButton, BM_SETIMAGE, (WPARAM)IMAGE_BITMAP, (LPARAM)hBitmap);
I havenottried Cyrillic characters,but I would guessyou just need to send them in the third parameter of theCreateWindowExcall, after setting a Cyrillic font.
[edit]
Cyrillic also works fine.

If you run into the problem in 2018 --> you simply need to enable visual style first!
Then the posted codes should be working.
