Question

使用RAPI2将文件从PC发送到远程设备。

使用不带Threads的行时，它可以正常工作：

RemoteFile.CopyFileToDevice(PdtRemoteDevice, "C:\sample.txt", "\test\sample.txt", True)

但是当我尝试将该行放在Thread内时，它会返回设备未连接的错误。

如何使用线程使用RAPI2的{{1}}？

不使用CopyFileToDevice会使应用程序看起来像挂起。因此，我认为用户不会欣赏那些没有响应的应用程序。

我的代码：

Thread

Answer 1

试试这个并告诉我它是否有效：

Private Sub UploadDatabase()
    Using rdm As New RemoteDeviceManager
        Using d As RemoteDevice = rdm.Devices.FirstConnectedDevice
            If Not (d Is Nothing) Then
                RemoteFile.CopyFileToDevice( _
                    d, "C:\sample.txt", "\test\sample.txt", True)
            End If
        End Using
    End Using
End Sub

Answer 2

创建表单，添加RAPI2库作为参考，然后添加两个按钮和此代码：

Imports System.Devices
Imports System.Devices.RemoteDeviceManager
Imports System.Devices.RemoteDevice
Imports System.Devices.RemoteFile


Public Class Form1
    Dim dev As RemoteDevice
    Dim mgr As New System.Devices.RemoteDeviceManager


    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        dev = mgr.Devices.FirstConnectedDevice

        If dev Is Nothing Then
            MsgBox("No device connected")
        Else
            MsgBox("Connected to: " & dev.Name)
        End If

    End Sub

    Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click
        Dim RAPIfile As RemoteFile

        dev = mgr.Devices.FirstConnectedDevice
        Try
            RAPIfile.CopyFileToDevice(dev, "C:\temp\test1.txt", "\Application\Inventory\test1.txt", True)
        Catch
            MsgBox("error")
        End Try

        RAPIfile = Nothing

    End Sub

End Class

使用从PC到远程设备的线程移动文件
