Display a wait cursor while form is busy
提问by John
I have an application that is doing some work that takes time and i wish to use the wait cursor but i cant find how.
我有一个应用程序正在做一些需要时间的工作，我希望使用等待光标，但我找不到如何使用。
Cursor = Cursors.WaitCursor 'and some various me.Cursor / current.cursor
CalulateBalance()
FTableAdapter.FillDateID(BudgetDataSet.FQuartaly)
FQuartalyDataGridView.Refresh()
MsgBox("Completed updating Balances", MsgBoxStyle.OkOnly)
Cursor = Cursors.Default
回答by Joe Uhren
Unless you are want to run your long processes on another thread you only have to stick in a Application.DoEvents()line after changing the cursor and before the long process.
除非你想在另一个线程上运行你的长进程，否则你只需要Application.DoEvents()在更改光标后和长进程之前保持一行。
Cursor = Cursors.WaitCursor 'and some various me.Cursor / current.cursor
Application.DoEvents()
CalulateBalance()
FTableAdapter.FillDateID(BudgetDataSet.FQuartaly)
FQuartalyDataGridView.Refresh()
MsgBox("Completed updating Balances", MsgBoxStyle.OkOnly)
Cursor = Cursors.Default
