VB里如何改变命令按钮中文字的颜色？

不能直接通过属性框修改按钮中文本的颜色
根本没有foreColor属性
下边是一个参考方法
首先请把要改的按钮的Style设置为1

在工程中添加以下模块(Module):
Module modExtButton.bas

Option Explicit

'==================================================================
' 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
'

然后回到FORM中：
添加CommandButton，不必更改它们的名称，将它们的Style设为Graphical，给第3个按钮设置一幅图片。
CommandButton也可以放置在一个容器如PictureBox或Frame中，模块会判断，如果需要的话将CommandButton的容器也子类化。

在Form中的代码：
Private Sub Form_Load()

'Initialize each button color.
SetButton Command1.hWnd, vbRed
SetButton Command2.hWnd, &H8000& '深绿色
'Assign this one a DT_BOTTOM alignment because
SetButton Command3.hWnd, vbBlue, DT_BOTTOM '含有图片，将文本放置在按钮底部
SetButton Command4.hWnd, &H8080& '暗棕黄色

End Sub

Private Sub Form_Unload(Cancel As Integer)

'手动解除按钮的子类化
'这并不是必须的
RemoveButton Command1.hWnd
RemoveButton Command2.hWnd
RemoveButton Command3.hWnd
RemoveButton Command4.hWnd

End Sub

For m = 0 To 9
SetButton CmdNum(m).hWnd, vbBlue
Next
For n = 1 To 4
SetButton CmdCal(n).hWnd, vbRed
Next
For l = 2 To 4
SetButton CmdOth(l).hWnd, vbRed
Next

如果你确实不懂他们说的,教你一招最笨的方法在按钮上面画一个label控件,
设置背景透明
,然后将按钮的文字去掉,在这个label的caption属性里面输入
它的文字
,并设置字体颜色等,然后写单击事件的时候
就写这个label的单击事件
,

点击按钮,右边属性,按分区,最后一项FOUT,设置.

按钮 ... 属性 ... 找 ForeColor ...

修改就可以 ...

只能改变“字体” “大小” “效果” 上面的只能是黑色的，可能要调用API吧
在强的自己些个按钮的类。
