I'm trying to add in an Color Property to the control I'm creating. I want it to act like the BackColor Property and access an an StandarColor Page.

How do I do this?

Hi!

If you wan't the Color Property's apper in properitys dialog as VB activeX controls do, also can add more of these it's easy to use a extra label control or a control which has this properity and map this properity to your control as different name.

Use ActiveX control interface Wizard.

Go to VB IDE menu Add-Ins start Add-In manager and load this wizard and run it. It has stdnames on list selct only BackColor Then use it to map these properity names Usercontrol then you shuld have it.


Save the existing code as backup firts the Wizard makes modifications.

Here is one simple mapping code:

Public Property Get BackColor() As OLE_COLOR
    BackColor = UserControl.BackColor
End Property

Public Property Let BackColor(ByVal New_BackColor As OLE_COLOR)
    UserControl.BackColor() = New_BackColor
    PropertyChanged "BackColor"
End Property

'Load property values from storage
Private Sub UserControl_ReadProperties(PropBag As PropertyBag)

    UserControl.BackColor = PropBag.ReadProperty("BackColor", &H8000000F)
End Sub

'Write property values to storage
Private Sub UserControl_WriteProperties(PropBag As PropertyBag)

    Call PropBag.WriteProperty("BackColor", UserControl.BackColor, &H8000000F)
End Sub

Hi!

VB IDE menu Add-Ins start Add-In manager and load this wizard and run it.

Available only it a control project is loaded

Go to Add-Ins > Add-In Manager

On that list:

"VB 6 ActiveX Ctlr Intreface Wizard"

It cold be on the menu if it's loaded from the manager.

Do map properities to the control, standard names are available there, just select the one you need. It has helpfile. This is one of the best wizards whit VB.
