[DotNetDevelopment] Re: Update image for every 5 sec. Asynchronously

[Bhargav Patel]

I thing u can use threading to update Image asynch. and plz write code
like follows

first declare delegate of your update method like

perivate delegate  sub RefreshImageCallBack()

then define procedure like this

' ' Refresh Image actually refresh/Alter Image.
' ' Here Invoke method is required because our Panel is created from
different thread then we actualy created It so It can give error.

private Sub RefreshImage()

        if  pnlImage.InvokeRequired then
              dim d as New RefreshImageCallBack
               d.Invoke
       else
              pnlImage.BackgroundImage= YourImage
       end if

end sub

' this procedure will be preocedd in infinite loop and sleep method
will ensure your time duration between refreshes.

Private Sub StartImageRefresh
         while true
            Threading.Thread.Sleep(5000)
            Refreshimage()
         end while
end sub

then start your refreshing in different thread like in Form_Load
method or
in New after Initialize component

dim th as new thread(addressof StartImageThread)
th.Start


I had done many refreshing tasks in widows application from this
method and its working fine without affecting main application
If you found any problem then can contact me at this thread . I wrote
this code without any compilation so it can be compiler error but
procedure
is same.
