Answer 1

VB6按钮只能改背景色，不能改前景色，如果一定要改的话，需要大量的API函数和代码 ，有一个变通的方法，就是自己做一个按钮的图形文件，将按钮的Style属性设置为1 - Graphical，Picture属性设置为图片文件 ，见图：

Answer 2

给你个变通的方法：改用cleckbox按钮，将属性里的style设为1-Graphical。这样外观就与命令按钮一致了，然后在Forecolor设置字体颜色。
当然为了防止按扁原有程序加个if：
if check1.value=1 then
*********
正常代码
********
end if
希望对你有帮助童鞋

Answer 3

在设计中直接改变forecolor属性
或者在工程中添加以下模块（Module）：
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

　　将 Form 命名为 frmDemo。添加 4 个 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 中加入如下代码：
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
