Usercontrols ("Project" -> "Add UserControl...").

If you set the form's TopLevel property to False and its Parent property to
the container you want to put it in (Panel, form, etc), it should work
fine.  When you show the form, it will appear inside the container.

Here is some code that I use to do exactly that. I have a series of modules
that implement an interface in a class file to be consistent. The modules
show a form which may show other modal dialogs. The external app
instantiates the module, then uses the following interface method to 'open'
it. If you are going to have the 'module' raise events, you have to do this
by using an interface. The DotNet documentation has a 2-pager that covers
the interface part. See "Walkthrough: Creating and implementing Interfaces".
I also provide methods in the interface to handle a resize of the app to be
able to call the module to resize itself. Likewise, a 'close' method is
useful also shown below.

Public Function OpenModule(ByVal oParent As Object, ByRef oChild As Object)
As Boolean Implements ModInterface.IModule.IGUIModule.OpenModule

Try

frmModule.Parent = oParent ' Form parent

frmModule.gobjClassParent = Me ' Form's class parent

frmModule.Show()

mbolClientOpen = True

Catch ex As Exception

MsgBox(ex.Message, MsgBoxStyle.Critical)

End Try

End Function

Public Sub ResizeModule(ByVal X As Integer, ByVal Y As Integer, ByVal Width
As Integer, ByVal Height As Integer) Implements
ModInterface.IModule.IGUIModule.ResizeModule

Try

frmModule.SetBounds(X, Y, Width, Height)

Catch ex As Exception

PostError(MODNAME, "ResizeModule", ex)

End Try

End Sub

Public Sub CloseModule() Implements
ModInterface.IModule.IGUIModule.CloseModule

Try

frmModule.Visible = False

frmModule.Parent = Nothing

Catch ex As Exception

PostError(MODNAME, "CloseModule", ex)

End Try

End Sub
