大家好! 我開了一個 thread-S 監聽有無 client連入, 當有 client連入時, textbox印出 "client no.? 連入", 並開一個 thread-C 處理資料的傳送接收。 code片段如下: Private Sub btOpenServer_Click() Dim ListenThread As New Thread(AddressOf StartListen) ListenThread.IsBackground = True ListenThread.Start() End Sub Private Sub StartListen() UpdateText("Server started at: " + serverIP.ToString() + ":" + Port + ".", "on") While True linkCount += 1 ClientSocket = serverSocket.Accept() UpdateText("Client No:" + Convert.ToString(linkCount) + " started!", "on") >>>此時 textbox顯示 Client No:1 started!<<< Dim client As New handleClinet client.startClient(ClientSocket, Convert.ToString(linkCount)) End While End Sub >>> 以下是另一個 .vb檔 <<< Module HandleClient Public Class handleClinet Public Sub startClient(ByVal inClientSocket As Socket, ByVal clineNo As String) Dim ctThread As Threading.Thread = New Threading.Thread(AddressOf doChat) ctThread.Start() End Sub Private Sub doChat() Dim networkStream As New NetworkStream(clientSocket) networkStream.Read(bytesFrom, 0, CInt(clientSocket.ReceiveBufferSize)) dataFromClient = System.Text.Encoding.ASCII. GetString(bytesFrom) ************** Form1.UpdateText("From client-" + dataFromClient) >>>此時 textbox依然只有顯示 Client No:1 started!<<< >>>並未顯示 From client-?????????? <<< End Sub End Class End Module 請問,為什麼 ***那行把資料傳回去時,textbox並未更新 "From client-" + dataFromClient 該行資料呢? 我下中斷去看,textbox的資料是有改變的, 但是實際上看到的卻是沒變的。 感謝賜教! -- ※ 發信站: 批踢踢實業坊(ptt.cc), 來自: 61.221.47.106 ※ 文章網址: https://www.ptt.cc/bbs/Visual_Basic/M.1464148315.A.651.html ※ 編輯: Xavier (61.221.47.106), 05/25/2016 11:53:59
