疑問 - VB6 ,有一Command鈕 要如何防止被連擊2次

[飛行船大大]

有一Command鈕 click事件內有許多inet的下載作業.
請問 在執行完成作業之前 要如何防止被連擊2次 ??
謝謝~

參考看看

Public Declare Sub CopyMemory Lib "kernel32" Alias "RtlMoveMemory" ( _
    hpvDest As Any, _
    ByVal hpvSource As Long, _
    ByVal cbCopy As Long)
Dim gbyteDLData() As Byte
Dim gDataContentLength As Long

==========以上建一個 共用模組.bas==========

Private Sub Inet1_StateChanged(ByVal State As Integer)

On Error GoTo EXITSUB

    Select Case State
    Case icResponseCompleted '此請求已經完成，並且所有資料均已接收到
    Dim tmpB() As Byte
    Dim r As Long

        DoEvents
        '**獲得開頭段資料 及 長度資訊
        Dim S As String
        If gDataContentLength = 0 Then
           gbyteDLData = Inet1.GetChunk(5120, icByteArray)
        End If
        S = Inet1.GetHeader("Content-Length")
        If Len(S) = 0 Then gDataContentLength = 0 Else gDataContentLength = CLng(S)

        '**持續拼接資料，直到無資料為止
        Do While True
           tmpB = Inet1.GetChunk(5120, icByteArray)
           If LenB(tmpB) = 0 Then Exit Do
           
           r = UBound(gbyteDLData) + 1
           ReDim Preserve gbyteDLData(0 To r + UBound(tmpB))
           CopyMemory _
               ByVal VarPtr(gbyteDLData(0)) + r, _
               ByVal VarPtr(tmpB(0)), _
               UBound(tmpB) + 1
               
           Erase tmpB
           DoEvents
        Loop
    End Select
    
EXITSUB:
    If Err.Number = 35758 Then Inet1.Cancel
    Err.Clear

    Command1.Enabled = True
    
End Sub

Private Sub Command1_Click()

    Command1.Enabled = False
    Call StartDownLoad '開始下載副程式

End Sub

在你要防止被連擊的_click程式下第一行
Command1.Enabled = False
中間過程放程式~
end sub之前放上這一行
Command1.Enabled = true
即可
