如何在VB.net中拖动文件并获取它的路径 [英] how to drag a file and get path of it in VB.net

问题描述

如何在Winform中实现Panel，当用户在其上拖动文件（一个简单的.txt文件）时，它应该接受它并将其路径存储到一个名为filepathname等的变量中，这个变量可以在之前使用。我可以找到有关如何实现拖放的示例，但不能找到如何获取路径并将其存储以供稍后在程序中使用的示例。使用：Visual Studio 2008 - Vb.net



谢谢！

How to implement a Panel in Winform , when a user drags a file on it (a simple .txt file) , it should accept it and stores its path into some variable called filepathname etc. which can be used earlier. I could find examples on how to implement drag and drop but not on how to get the path and store it for use later in the program. Using : Visual Studio 2008 - Vb.net

Thanks!

由我翻阅解决一些网站。我不知道为什么我不能早点找到它们！

Solved by me looking up through some sites. I dont know why i couldn't find them earlier!

Private Sub dropdpanel_DragEnter(sender As Object, e As DragEventArgs) Handles dropdpanel.DragEnter
        If e.Data.GetDataPresent(DataFormats.FileDrop) Then
            e.Effect = DragDropEffects.All
        End If
    End Sub

    Private Sub dropdpanel_DragDrop(sender As Object, e As DragEventArgs) Handles dropdpanel.DragDrop
        If e.Data.GetDataPresent(DataFormats.FileDrop) Then
            Dim MyFiles() As String


            ' Assign the files to an array.
            MyFiles = e.Data.GetData(DataFormats.FileDrop)
            'If there are more than one file, set first only
            'If you want another restrictment, please edit this.
            filepathname = MyFiles(0)

        End If
    End Sub
