I am creating an application that allows the user to preview files using Web Browser Control in vb.net and also allow to input some other details using textbox. After the details was saved, the file will be removed from the list and will be added to the list of finished files and will be automatically renamed. The problem is, when I am trying to rename the file, an exception occur stating "The process cannot access the file because it is being used by another process." How can I terminate the process for me to able to rename the file?

原始文件:它是完整的目的地和文件名.
SelectedFile :它是文件名.
ClearEmpData :清除字段.

Original_File: it is the complete destination and filename.
SelectedFile: it is the filename.
ClearEmpData: clear the fields.

    Private Sub btnSave_Emp_Click(sender As Object, e As EventArgs) Handles btnSave_Emp.Click
    Dim SP_Name As String = "SP_EmpData"
    Dim SP_Param As String() = {"@DType", "@Equip", "@EmpNo", "@LN", "@FN", "@Path"}
    Dim SP_Val As String() = {cbDataType_emp.Text, Equipment_Type, Emp_No, LastName, FirstName, New_Path}

    If cbDataType_emp.SelectedIndex <= 0 Then
        MyFile.Message.ShowEntryError("Please select data type.", cbDataType_emp)
        Exit Sub
    Else
        If Not MyFile.Process.MoveFiles(Root_Dir, dgvEncode.SelectedCells.Item(1).Value, cbDocType.Text) Then Exit Sub
        If Not ExecuteSaveProcedure(SP_Name, SP_Param, SP_Val) Then Exit Sub

        Original_File = dgvEncode.SelectedCells.Item(2).Value

        Dim dr As DataGridViewRow
        For Each dr In dgvEncode.SelectedRows
            dgvEncode.Rows.Remove(dr)
            dgvDone.Rows.Add(dr)
        Next
        dgvEncode.CurrentCell.Selected = dgvEncode.Rows.Count
        ClearEmpData()
        dgvDone.ClearSelection()

        Try
            My.Computer.FileSystem.RenameFile(Original_File, "xDone_" & SelectedFile)
        Catch ex As Exception
            MyFile.Message.ShowWarnning(ex.Message)
            Exit Sub
        End Try

    End If
End Sub

推荐答案

我已经解决了这个问题.我创建了一个临时文件进行预览，然后重命名了原始文件，然后删除了该临时文件.

I already solved this problem. I created a temporary file to be preview then rename the original file and then delete the temporary file.
