If you look at the documentation for the AutoScrollPosition property, it states that negative values are returned for the X and Y properties of the Point returned from the property if a user has scrolled away from the starting position (0,0). Make sure you negate these values before factoring them into your new position for child panels. See DirectX 9.0 - Get Ambient with DirectSound[^] which should contain a sample like this (judging by the way the program works). -----BEGIN GEEK CODE BLOCK----- Version: 3.21 GCS/G/MU d- s: a- C++++ UL@ P++(+++) L+(--) E--- W+++ N++ o+ K? w++++ O- M(+) V?

Also, read the documentation for the System.Windows.Forms.Control class. That has all the mouse events and properties you need to do this. -----BEGIN GEEK CODE BLOCK----- Version: 3.21 GCS/G/MU d- s: a- C++++ UL@ P++(+++) L+(--) E--- W+++ N++ o+ K? w++++ O- M(+) V?

Return Value A Type object representing the interface with the specified name, implemented or inherited by the current Type, if found; otherwise, a null reference (Nothing in Visual Basic). ...straight form the Type.GetInterface documentation. As a norm, methods that return reference types typically return null in cases like this, or just throw an exception if there's an error. -----BEGIN GEEK CODE BLOCK----- Version: 3.21 GCS/G/MU d- s: a- C++++ UL@ P++(+++) L+(--) E--- W+++ N++ o+ K? w++++ O- M(+) V?

Im my opinion, a good example of the uses of attributes is when it comes to describing properties for the property explorer in Visual Studio.net. using System; using System.ComponentModel; namespace Examples { public class ExampleControl : UserControl { private IndentStyle m_eExampleProperty = IndentStyle.Smart; [ Category("Design"), Description("Gets/sets an example value."), DefaultValue(IndentStyle.Smart), Browsable(true) ] public IndentStyle ExampleProperty { get { return m_eExampleProperty; } set { m_eExampleProperty = value; } } } } This would produce this kind of output: If you want to try this out, just cut-and-paste the code into a source file, and create an instance of the control on the designer form. - Daniël Pelsmaeker Microsoft is to quality software what McDonalds is to gourmet cooking

Cool. Good to hear it, and look forward.

I thought someone would have come up with something :) Probably as easy as copying the wizards probably. Not that I ever use any! :laugh: Give them a chance! Do it for the kittens, dear God, the kittens! As seen on MS File Transfer: Please enter an integer between 1 and 2.

Aligning aligns two or more controls to each other, not to the form. Thus if you select two or more controls, you'll get your align buttons. What you really want is Docking... check out the Dock property for your control. Paul
