Question

在VB 6中如何使用变量而不是固定名称来引用控制标签，例如LUH01（如下所示），它不允许循环。

Frm_Dispo_Prof_Grille.LUH01.BackColor = &HFF00&

Answer 1

您可以通过Controls Collection：

来引用它

Frm_Dispo_Prof_Grille.Controls("LUH01").BackColor = &HFF00&

但是，要小心。如果您需要引用不属于标准/内置属性的属性/方法，则必须将控件转换为类型：

Dim lbl as Label

Set lbl = Frm_Dispo_Prof_Grille.Controls("LUH01") 
lbl.BackColor = &HFF00

Answer 2

我想你想创建一个控制数组

您可以通过创建1控件，并将其Index属性设置为0（而不是空）

来实现

然后，您可以加载新控件并在循环中使用它们

例如，加载一些命令按钮并将它们放在循环中：

'1 form with :
'  1 command button: name=Command1  index=0

'Number of command buttons to use in the loop
Private Const NRBUTTONS As Integer = 5

Option Explicit

Private Sub Form_Load()
  Dim intIndex As Integer
  'change the caption of the default button
  Command1(0).Caption = "Button 0"
  For intIndex = 1 To NRBUTTONS - 1
    'load an extra command button
    Load Command1(intIndex)
    'change the caption of the newly loaded button
    Command1(intIndex).Caption = "Button " & CStr(intIndex)
    'newly load command buttons are invisible by deafult
    'make the new command button visible
    Command1(intIndex).Visible = True
  Next intIndex
End Sub

Private Sub Form_Resize()
  'arrange all loaded command buttons via a loop
  Dim intIndex As Integer
  Dim sngWidth As Single
  Dim sngHeight As Single
  sngWidth = ScaleWidth
  sngHeight = ScaleHeight / NRBUTTONS
  For intIndex = 0 To NRBUTTONS - 1
    Command1(intIndex).Move 0, intIndex * sngHeight, sngWidth, sngHeight
  Next intIndex
End Sub

使用变量作为标签控件名称
