I tried this code:

Private Const OCR_NORMAL As UInteger = 32512
<DllImport("user32.dll")> _
Private Shared Function LoadCursorFromFile _
                        (ByVal lpFileName As String) _
                        As IntPtr
End Function
<DllImport("user32.dll")> _
Private Shared Function SetSystemCursor _
                        (ByVal hCursor As IntPtr, _
                        ByVal id As Integer) _
                        As Boolean
End Function
<DllImport("user32.dll")> _
Public Shared Function LoadCursor(ByVal hInstance As IntPtr, _
                                  ByVal id As UInteger) _
                                  As IntPtr
End Function
Private Sub frm_Load(ByVal sender As System.Object, _
                               ByVal e As System.EventArgs) _
                               Handles MyBase.Load
   Dim cursor As IntPtr = LoadCursorFromFile("C:\cursor.cur")
   SetSystemCursor(cursor, OCR_NORMAL)
End Sub
Private Sub btn_Click(ByVal sender As System.Object, _
                      ByVal e As System.EventArgs) _
                      Handles btn.Click
    SetSystemCursor(LoadCursor(IntPtr.Zero, OCR_NORMAL), OCR_NORMAL)
End Sub

此代码用于更改光标，但它没有返回它：（

This code worked for changing the cursor, but it didnt return it back :(

推荐答案

在设置自定义光标之前，你有将当前光标写入应用程序的某个变量（不是像GetSystemCursor这样的函数吗？），以及当应用程序停止时（例如在FormClosing事件中，您将其设置回上面存储的原始值。

Before you set your custom Cursor, you have to write the current cursor into some variable of your application (isn't there a function like GetSystemCursor?), and when your application stops (e.g. in the FormClosing event), you set it back to the original value which you stored above.
