请问：怎么改变按钮上面字体的颜色的呢?
请问：怎么改变按钮上面字体的颜色的呢，我是用GETDC和SETTEXTCOLOR这两个函数写的，疑惑了怎么实现不了！
烦请帮忙！ --------------------编程问答-------------------- 改用optionButton不好吗,将属性Style设为1，外形和command一样，有属性设置前景色 --------------------编程问答-------------------- ' modExtButton.bas
'
' 本模块可让你改变命令按钮的文本颜色。
' 使用方法:
'
' - 在设计时将文本的Style设为Graphical.
'
' - 随意设定背景色和图象属性.
'
' - 在Form_Load中调用 SetButton :
' SetButton Command1.hWnd, vbBlue
' (你可以任意次的调用该过程甚至不必先调用 RemoveButton.)
'
' - 在Form_Unload中调用 RemoveButton :
' RemoveButton Command1.hWnd

--------------------编程问答-------------------- 跟1楼一样 用commandbutton --------------------编程问答-------------------- 甚至控件上可以加载图片 --------------------编程问答-------------------- 用 Microsoft Form2 2.0 Object Library 吧，按钮的背景色、字体颜色都能随意设置，操作简单。
--------------------编程问答-------------------- 有没有代码短点的 --------------------编程问答-------------------- 我说的那个，什么代码也不要啊，设计时就可以搞定。
运行时也可以用指令改变。
--------------------编程问答--------------------
对！这个可以轻松实现
补充：VB , 基础类
