Not sure how this works with Crystal Report, it works with "normal" forms. Trap Resize event and if minimizing, set WindowState back to normal [CODE=VB.NET] Private Sub Form1_Resize(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Resize ' If Me.WindowState = FormWindowState.Minimized Then Me.WindowState = FormWindowState.Normal End If End Sub[/CODE]

It seems that .NET does not support Indian formatting for some reason. You have to implement formatting yourself, for example write your own (overloaded) ToString method. Shouldn't be that hard to write code for this. I did find a one .NET implementation for this (both numbers and dates [URL="http://www.codeproject.com/KB/cs/NumberDateFormat.aspx"]Indian Number …

I don't do PocketPC programming but I think [ICODE]System.Threading.Thread.Sleep(240)[/ICODE] makes your "main" thread to sleep instead of "current" thread. As you can see, I'm not that familiar with threading either ;)

You're not sending 300 bytes, you're trying to send integer "300" [CODE=VB.NET]Try Dim ping As New System.Net.NetworkInformation.Ping Dim Buffer(299) As Byte ' A buffer for 300 bytes ' Fill Buffer() Return ping.Send(hostNameOrAddress, 5000, Buffer).RoundtripTime Catch ex As Exception MsgBox("Computer Ping Could Not Be Called") End Try[/CODE]

Classes have properties and methods. You pass an array between class instances either with properties which are of array type or by method's arguments which is an array type.

There's no API calls needed. If you have a picturebox control and an image file, you just do the following: [CODE=VB.NET]PictureBox1.Image = Image.FromFile("C:\somepic.jpg")[/CODE] Of cource, there are other ways to get and display images depending on the source of the image.
