我收到了标题中所述的错误,并且作为 vb.net 的新用户试图理解它。如果有人能解释解决此错误的正确方法,我将不胜感激,因为我没有足够的经验知道从哪里开始处理此类错误。
如果有帮助,这就是我想要做的。我在列表框中有一个上下文菜单,当我右键单击一个条目时,会显示该单元格中成员的值。消息框显示正确的值,但是当我单击关闭该框时,会出现此错误。非常感谢
Unable to cast object of type 'System.EventArgs' to type 'System.Windows.Forms.ToolStripItemClickedEventArgs'.
这是我认为我应该展示的代码。
Private Sub HideToolStripMenuItem_Click(ByVal sender As Object, ByVal e As ToolStripItemClickedEventArgs) Handles pnlContextMenuStrip1.ItemClicked, HideToolStripMenuItem.Click
'Get the text of the item that was clicked on.
Try
MessageBox.Show(txtCustomerActive.Text)
Catch ex As Exception
MessageBox.Show(ex.Message)
End Try
End Sub
Private Sub ContextMenuStrip1_Opening_1(ByVal sender As System.Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles pnlContextMenuStrip1.Opening
End Sub
更新:我在我的项目中启用了 Stirct On,在对代码进行了一些小的更改后,我留下了这个我认为是指错误的代码。
Error 1 Method 'Private Sub HideToolStripMenuItem_Click(sender As Object, e As System.Windows.Forms.ToolStripItemClickedEventArgs)' cannot handle event 'Public Event Click(sender As Object, e As System.EventArgs)' because they do not have a compatible signature.
