Hi, any ideas on making an animated progress kinda thing as in the explorer copying file box? (you know the two folders with the paper flying from one to the other?) does anyone know where i can find some of the animations and how i can display then while performing large operations to let the user know we're still alive?
hi,
About the animation that windows display when copying things,
well it's an avi in another form that opens in Modal way so
you can't interact with the calling or process form.
To make that you just load the avi in the little form and
start playing it when you begin the process and stop it
when the process is finished, and as in explorer there will
be the same problem that the animation could be "alive" but
the process could be "dead", that's what i think about it so
far.
Maybe someone else has the solution, but as far as i have
seen a dead process won't scream;)
Saludos...;)
You can find some graphics and animations in the 'Graphics' folder in the VB folder.
Hmmm, how can i play the avi? i have tried ActiveMovie control but i just get some System Error when i execute my program when this control is in use...

eh? en anglias svp? :P
In fact, I found the article on the TECHNET or MSDN.
Then, I use it in one of my VB program.
Good luck,

try the animation control in the 'Microsoft Windows Common COntrols 2-6.0' component then throw in some code like this:
Code:Private Sub Command1_Click()
If Me.Tag = "playing" Then
animation1.Stop
Me.Tag = "stopped"
Else
animation1.Play
Me.Tag = "playing"
End If
End Sub
Private Sub Form_Load()
animation1.Open "C:\Program Files\Microsoft Visual Studio\Common\Graphics\Videos\filecopy.avi"
End Sub
How about jus using Windows Media Player Control???
This is the easiest control ever made for playing sound and video!
