Hi all , i'm building a downloader using vb.net 2008 , all things is working good
but what my problem is when i try to show the file size in MB i can't show the number of digits before the dot , for example i want to show only 4 digits before the dot in the result as 3.1234 and not as 3.12345677
the code i use to convert bytes to MB in my project is as :

VB

Label1.Text = ((e.TotalBytesToReceive / 1024) / 1024) & "MB"

Try formatting the amount like this;

VB

Label1.Text = String.Format("{0:###,##0.0000}MB", (e.TotalBytesToReceive / 1024.0) / 1024.0))

Hope this helps,
Fredrik
