Hi Leute
Ich lade via Webclient eine datei runter.Alles gut soweit nur die Prozent anzeige springt von 0 direkt auf 100 wieso?

Hier der Code:

private: System::Void button1_Click(System::Object^  sender, System::EventArgs^  e) 
				{

						WebClient ^myClient = gcnew WebClient();
						myClient->Credentials = gcnew NetworkCredential("username","passwort"); //username and password
						Uri ^url = gcnew Uri("ftp://ftp.meineseite.de/test.zip");
						String ^file = "test.zip";

						myClient->DownloadProgressChanged += gcnew DownloadProgressChangedEventHandler(this, &Form1::s_DownloadProgressChanged);

						myClient->DownloadFileCompleted += gcnew AsyncCompletedEventHandler(this, &Form1::DownloadFileCompleted);

						myClient->DownloadFileAsync(url, file);

			 }

	private:		 System::Void s_DownloadProgressChanged(System::Object^ sender, System::Net::DownloadProgressChangedEventArgs^ e)
					{
						this->progressBar1->Maximum = 100;
						progressBar1->Value = e->ProgressPercentage;
						this->label1->Text = e->ProgressPercentage.ToString() + "%";// 
						this->label2->Text = e->ProgressPercentage.ToString();
						//progressBar1->Update();

					 }

		private:	 System::Void DownloadFileCompleted(System::Object^ sender, System::ComponentModel::AsyncCompletedEventArgs^ e)
					{
						MessageBox::Show("Download Completed");
					}
