下載後VB重置進度欄值

作爲一個練習，我試圖讓我的程序通過進度條下載文件。它下載它很好，進度條遵循，但問題是，下載完成後，它不會重置。這是按鈕和欄的代碼。下載後VB重置進度欄值

Private Sub Button1_Click_1(sender As System.Object, e As System.EventArgs) Handles Button1.Click 
    WC.DownloadFileAsync(New Uri("imageurlhere"), "c:\myfile.jpg") 
    If ProgressBar1.Value = ProgressBar1.Maximum Then 
     ProgressBar1.Value = ProgressBar1.Minimum 
    End If 
End Sub 

Private Sub WC_DownloadProgressChanged(ByVal sender As Object, ByVal e As DownloadProgressChangedEventArgs) Handles WC.DownloadProgressChanged 
    ProgressBar1.Value = e.ProgressPercentage 
End Sub

試試這個

Private Sub Button1_Click_1(sender As System.Object, e As System.EventArgs) Handles Button1.Click 
    WC.DownloadFileAsync(New Uri("imageurlhere"), "c:\myfile.jpg") 
End Sub 

Private Sub WC_DownloadProgressChanged(ByVal sender As Object, ByVal e As DownloadProgressChangedEventArgs) Handles WC.DownloadProgressChanged 
    ProgressBar1.Value = e.ProgressPercentage 
    If ProgressBar1.Value = ProgressBar1.Maximum Then 
     ProgressBar1.Value = ProgressBar1.Minimum 
    End If 
End Sub

Did'nt工作，試圖在此之前（改變位置上的復位功能） – Thomja 2013-05-05 17:30:05

設置ProgressBar1.Maximum = 1（100％值） – matzone 2013-05-05 23:10:02

出於某種原因，現在它的工作原理... ish，if函數會重置欄，但問題在於，在if函數重置它之前，綠色條不能完成，但可以通過縮短我認爲的條來解決。 – Thomja 2013-05-06 21:57:02
