I'm not good at English Just ignore this warning, because you assigned a value to dbReader in Try Statement Think about Try: It means code in Try-Catch can be exited at any time.

I'm not good at English I can't answer because it's a very hard problem. However, you can go to this link and research: https://sourceforge.net/projects/clamwin/files/[^] It's about ClamWin Antivirus, a free and open source antivirus program. But may be it's written in C++.

I'm not good at English. Look at this registry key HKEY_CURRENT_USER\Control Panel\Desktop You can find a lot of values in this key. The value named "WallPaper" contains path of the desktop background image. Some of other values describe how should the image be displayed. Use My.Computer.Registry.SetValue(keyname as String, valueName as String, value as Object) to change the registry. This is an example code

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
My.Computer.Registry.SetValue("HKEY_CURRENT_USER\Control Panel\Desktop", "WallPaper", "D:\1.jpg")
End Sub

When you click the Button1, it changes your desktop background image path to "D:\1.jpg" Good luck!

I'm not good at English. Not enough data to answer, because you didn't say about all the parts in your project and your project name. May be you have a class named "DateCalc2008" and a form named "Calculator". The form "Calculator" has a control named "StartDatePicker", and you created a subroutine which handles "StartDatePicker.ValueChanged" event. The error is: The form "Calculator" doesn't have a member named DateCalc2008. You should fix your code like this:

Dim myCalc As New {project name}.DateCalc2008

I hope this will be an useful answer. Good luck !

If you are using Microsoft Visual Studio 2005, you can find a compressed archive in this folder: C:\Program Files\Microsoft Visual Studio 8\Common7\VS2005ImageLibrary Extract the archive by using WinRAR or WinZip, then you can use everything, include icons in the extracted folder. Do similar things with other versions of Microsoft Visual Studio .NET Good luck!
