Hi all,

am working on vb.net 2008 application. First am created on Form called SM_Progress.vb. In that i added the progress bar control and set merqueryAnimationspeed 30. Am created one more windows form and added two button and one textbox and folder browsingDialog. Now for me i want show the SM_progress form when am clicking the one button. i wrote the code like this in click event.

SM_Progress.Show()
Application.DoEvents()

它仅显示表单.Progress bar不会旋转..如何在按钮click事件中执行特定操作的进度条.?

Its only showing the form .Progress bar is not rotating.. How can i run the progress bar for particular operation done in the button click event.?

推荐答案

设置样式?

Have you set the Style?

myProgressBar.Style = ProgressBarStyle.Marquee;

应该做到这一点.

要显示ProgressBar的工作状态，您必须使用Timer控件.在Timer_Tick事件中Timer控件的代码编写以下代码:

To show ProgressBar working you have to use Timer control.On Timer_Tick event of Timer control write the following code :

Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
        ProgressBar1.Value = ProgressBar1.Value + 1
End Sub

现在在打开SM_Progress Form的Button上编写以下代码:

Now write following code on Button where you open SM_Progress Form :

Timer1.Interval = 100
Timer1.Enable = True
Timer.Start()

希望对您有帮助. :)

I hope it will help you. :)
