自己编写vb进度条控件

本文已参与「新人创作礼」活动,一起开启掘金创作之路。

主程序代码：

Option Explicit

Dim i As Double

Private Sub Command1_Click()
    i = 0
    Timer1.Interval = 50
    Timer1.Enabled = True
End Sub

Private Sub Timer1_Timer()
    i = i + 0.05
    ProcessBar1.Percent = i
    If i > 1 Then Timer1.Enabled = False
End Sub

 控件代码：

Option Explicit

Public Enum FigureStyle
    eOnlyValueInt
    eOnlyValueDouble
    ePercentInt
    ePercentDouble
End Enum

Private dblMyPercent As Double

Private Max As Long, Min As Long

Private Sub UserControl_Initialize()
    Min = 0
    Max = 100
'    lngMyValue = 30
    dblMyPercent = lngMyValue / (Max - Min)
    lblValue.Caption = Int(dblMyPercent * 100) & "/100"
    UserControl.Height = lblBase.Height
    intMsgStyle = ePercentInt
    
    Call setLabelSize
