OpenFileDialogue打开两次

问题描述

我有此代码:

    Private Sub btnChangeDirCfg_Click(sender As Object, e As EventArgs) Handles btnChangeDirCfg.Click
        Dim CfgDialogue As New OpenFileDialog()                                     'Using the new Dialogue box;
        CfgDialogue.Filter = "Configuration Files (*.BLK)|*.BLK"                    '[1/2] Set Dialogue params
        CfgDialogue.ShowDialog()                                                    '[2/2] Show the dialogue box

        If (CfgDialogue.ShowDialog() = System.Windows.Forms.DialogResult.OK) Then
            CfgFile = CfgDialogue.FileName                                           'Store Filename as Var
            txtShowVarCfg.Text = (CfgFile)                                           'Using Var, present the files location
            My.Settings.SavedConfig = (CfgFile)                                      'Save config file location to config
        End If
    End Sub

Public CfgFile As String = String.Empty

我无法弄清楚问题的原因.

I can't figure out the cause of the problem I have.

当我按下按钮时，对话框及其过滤器会正确弹出.我选择名为"config.blk"的文件.单击打开"按钮(传递为确定")后，将打开一个新的副本对话框，但文件名已作为从中选择的目录填充 上一个对话框.文本字段也仅在第二对话框关闭后才填写:(

When I hit the button, the Dialog pops up correctly with its filter. I choose the file named "config.blk". After I click the Open button (passed as OK), a new replica dialog box opens but the filename is already filled in as the selected dir from the previous dialog box. The text field is only filled in after the 2nd dialog box has been closed too :(

我不知道为什么会这样.希望有人能提供帮助:)

I've no idea why this is happening. I hope someone can help :)
