使用WINSOCK
我點按鈕時會去呼叫 sending程式 待server回覆或Timeout時 將結果傳回

我是希望在執行第一次時如果還沒有接收到SOCK的回覆時 不要送出第二次
但不知為什麼 點兩次按鈕（中間隔五秒） 他還是直接送給SOCK Server而不是
等第一次結束後才接著送出去 而且sending的結果是錯誤的
我想程式一定有問題 只是找不到 〉：〈


程式如下





Private ackMsg As String Private Sub CWINSockTimer_Timer() CWinsock.Close B_Sending = False CWINSockTimer.Enabled = False ackMsg = "[Err]:TimeOut~" End Sub Private Sub Form_Load() B_Sending = False CWINSockTimer.Enabled = False End Sub Private Sub Form_Unload(Cancel As Integer) CWinsock.Close End Sub Private Sub CWinsock_Connect() If CWinsock.State = sckConnected Then CWinsock.SendData sendStr Else ackMsg = CWinsock.State End If End Sub Public Function sending(ByVal sockHost As String, ByVal sockPort As Integer, ByVal tempStr As String, ByVal t_time As Integer) As String On Error GoTo Oops Dim RegTime As Variant RegTime = Now Do Until B_Sending = False Sleep 1 DoEvents If DateDiff("s", Now, RegTime) > t_time Then sending = "[Err]:TimeOut" Exit Function End If Loop If B_Sending = False Then B_Sending = True CWINSockTimer.Enabled = True CWINSockTimer.Interval = CLng(t_time) * 1000 sendStr = tempStr CWinsock.RemoteHost = sockHost CWinsock.RemotePort = sockPort CWinsock.Close ackMsg = "" CWinsock.Connect Do Until ackMsg <> "" Sleep 1 DoEvents If DateDiff("s", Now, RegTime) > t_time Then ackMsg = "[Err]:TimeOut" Loop sending = ackMsg CWinsock.Close CWINSockTimer.Enabled = False B_Sending = False End If Exit Function Oops: sending = "[Err]:" & Err.Description CWinsock.Close CWINSockTimer.Enabled = False B_Sending = False End Function Private Sub CWinsock_DataArrival(ByVal bytesTotal As Long) On Error GoTo Oops Dim temp As String temp = String(bytesTotal, Chr$(0)) CWinsock.GetData temp, vbString, bytesTotal ackMsg = temp Exit Sub Oops: ackMsg = "[Err]:" & Err.Description CWinsock.Close CWINSockTimer.Enabled = False B_Sending = False End Sub Private Sub CWinsock_Error(ByVal Number As Integer, Description As String, ByVal Scode As Long, ByVal Source As String, ByVal HelpFile As String, ByVal HelpContext As Long, CancelDisplay As Boolean) ackMsg = "[Err]:" & Description & "Code:" & CStr(Number) CWinsock.Close CWINSockTimer.Enabled = False B_Sending = False End Sub
