Question

我编写了一个程序，可以根据用户请求更改字体和背景颜色。收到 backgroundColorData 和 textColorData 后我确实喜欢根据用户要求改变颜色，但我觉得有更好的方法让它成为我选择做的（我的代码可能会重复）其他问题我没有找到答案是如何使textColor / backgroundColor更多＆＃34;红＆＃34;或更多＆＃34;蓝色＆＃34;

  Select Case backgroundColorData
        Case Is = "Black"
            Selection.Interior.Color = RGB(0, 0, 0)
        Case Is = "Red"
             Selection.Interior.Color = RGB(255, 0, 0)
        Case Is = "Blue"
             Selection.Interior.Color = RGB(0, 0, 255)
        Case Is = "White"
             Selection.Interior.Color = RGB(255, 255, 255)
  End Select


    Select Case textColorData
        Case Is = "Black"
            Selection.Font.Color = RGB(0, 0, 0)
        Case Is = "Red"
             Selection.Font.Color = RGB(255, 0, 0)
        Case Is = "Blue"
             Selection.Font.Color = RGB(0, 0, 255)
        Case Is = "White"
             Selection.Font.Color = RGB(255, 255, 255)
     End Select

任何帮助都将不胜感激。

Answer 1

Sub tester()

    Dim backgroundColorData As String, textColorData As String

    backgroundColorData = "Blue"
    textColorData = "White"

    With Selection
        .Interior.Color = NameToRgb(backgroundColorData)
        .Font.Color = NameToRgb(textColorData)
    End With

End Sub

'map a color name to an rgb value
Function NameToRgb(sName As String) As Long
    Dim arrNames, arrRGB, v
    arrNames = Array("black", "red", "blue", "white")
    arrRGB = Array(RGB(0, 0, 0), RGB(255, 0, 0), _
                   RGB(0, 0, 255), RGB(255, 255, 255))

    v = Application.Match(LCase(sName), arrNames, 0)
    If Not IsError(v) Then
        NameToRgb = arrRGB(v - 1)
    Else
        NameToRgb = vbBlack 'default...
    End If
End Function

如果要为“更红”找到确切的颜色值，请将单元格中的背景设置为所需颜色，选择单元格，然后在VB编辑器中立即显示窗格：

? Selection.Interior.Color

复制数字并使用它代替RGB（）值

编辑：好的，现在我明白你的意思是让细胞更红...

Sub MoreRed(c As Range)
    Dim R As Long, G As Long, B As Long, clr As Long

    clr = c.Interior.Color
    B = clr \ 65536
    G = (clr - B * 65536) \ 256
    R = clr - B * 65536 - G * 256
    'Debug.Print R, G, B
    R = Application.Min(R + 20, 255) 'more red...
    c.Interior.Color = RGB(R, G, B)
End Sub

欢迎使用堆栈溢出。

你可以用这样的单一功能来实现 -

Function setColor(SelectionData As String) 

 Select Case SelectionData As String
      Dim returnValue As String  
        Case Is = "Black"
            returnValue  = RGB(0, 0, 0)
        Case Is = "Red"
             returnValue  = RGB(255, 0, 0)
        Case Is = "Blue"
             returnValue  = RGB(0, 0, 255)
        Case Is = "White"
             returnValue  = RGB(255, 255, 255)
     End Select  
return returnValue  
End Function

然后只需调用你的函数 -

setColor(textColorData)

Excel：使用rgb
