vb.net - 更改光标 VB.NET

Question

当它是 ToolStripButton.click 事件时，我无法更改光标。

我有 2 个名为“Rechercher”的按钮。

已编辑:只有按钮可以工作。 ToolStripButton 似乎取消了我的光标... 感谢您的帮助

Public Class FenetrePrincipale

    Private WithEvents _btnRechercher As New Windows.Forms.ToolStripButton("Rechercher")
    Private WithEvents btnRechercherAccesBtn As New Button

    Private Sub Rechercher(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles _btnRechercher.Click, btnRechercherAccesBtn.Click
        Try
            Me.Cursor = Cursors.WaitCursor
            'WAITING FOR THE CODE TO FINISH (2 sec)
        Finally
            Me.Cursor = Cursors.Default
        End Try
    End Sub
End Class

Answer 1

也许你应该尝试一些采样器，例如:

Private Sub MainFrame_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
  Search()
End Sub

Private Sub Search()
Try
  Me.Cursor = Cursors.WaitCursor
  UseWaitCursor = True
  Application.DoEvents()
  Threading.Thread.Sleep(1000) 'WAITING FOR THE CODE TO FINISH
Finally
   UseWaitCursor = False
   Me.Cursor = Cursors.Default
   Application.DoEvents()
End Try
End Sub

问题是代码应该执行的地方没有任何暂停，所以它运行得很快。
