The article is updated! See below for the changes!

Introduction

This property list control is similar to other property lists available, with two main differences:

  1. It's very easy to implement.
  2. It's implemented as an ActiveX control, so it's suitable for C++, C#, and VB as one. Also, it can be placed on an HTML page or any other container that supports ActiveX and script.

Reference

Properties
  • BorderStyle As BorderStyle

    The border style of the control.

    BorderStyle enum:

    • BorderFlat = 3 - BDR_RAISEDOUTER|BDR_RAISEDINNER, BF_FLAT
    • BorderStatic = 4 - BDR_SUNKENINNER
  • Precision As Short

    • ButtonType - the type of the button.
    • Value - passed ByRef (as pointer) allowing you to set a new value on function return.

* Note that some of the controls have a default action for button click, as the color button, linkbutton, mail button etc...

History

Update - 04/11/2004

New Properties
  • ShowDescription As Boolean

    Controls display of the description (True/False).

New Methods
  • CloseAll()

    Closes all the categories (useful if you'd like to start the list when all the categories are closed. You can fill the list then call CloseAll() to close the categories).

New button types
  • ButtonMultyText = 10 - Creates a text window five rows high for multiple lines text.
  • ButtonButton = 11 - Creates a button which occupies the entire row.
  • ButtonFunction = 12 - Creates a property whose value is calculated from the provided function which may be based on other properties. For example:

    You have a property named Diameter and its value is 10. You add a function type property named area, click on its button, the "Enter function" dialog appears where you write - 3.14 * ([Diameter]/2)^2. After you close the dialog, the value displayed in the property would be: 78.5. If you now change the Diameter to 4, the Area property will automatically update to 12.56.

  • ButtonPicture = -1 - The passed string is a path to an image file (you can also pass images as IDispatch interface).

GeneralReally nice, some bugs/problems PinmemberPartyPaul19-Apr-07 3:47 
First bugs which i encountered so far:
 
In the CEditItem::OnKillFocus procedure there is no check for bChange to call Apply, so Apply ist called even if u press Escape and KillFocus is called.
 
For people that have problems (i.e. the german üäöß) with the displayed Font, the main font (created in CMyList::CMyList()) uses the HEBREW_CHARSET, change that to the charset u need (in normal case ANSI_CHARSET should do it.
 

I have a special problem and dont know if it's me or better my App, the VS 2003 Compiler, or a "Bug" in the Control.
I use c++ and mfc and create the control at runtime which is no problem.
For that I created a wrapper class derived from CWnd(similar to the one in the sample project), in my window (no dialog), where the control should be placed, i have a member variable of that class, the Eventprocedures and create with CreateControl the Control.
No problems so far, the control is created, it fires the Events correctly etc. BUT, the Edit Controls dont get the VK_ESCAPE and VK_RETURN. All other keys are send to the Control.
My problem is now who takes the message and kills it.
Hierarchy is -> Mainfrm -> Propertybar(customwnd) -> Propertysheet(customwnd) -> Wrapperclass with Control if it helps.
I tried for hours and didnt get another solution as described down or found the one who kills the message and send it not to the Control.
My Solution was in the Wrapperclass:PretranslateMessage() i get the VK_ESCAPE & VK_RETURN message with the correct handle of the Control. So at this point I send it directly to the Control.
 
What i really dont understand is that in the Control i dont get ANY PretranslateMessage Calls in any of the windows/classes, is that COM related or why isnt it fired. Where can i get the Message before it's translated/dispatched ?!
Next problem is, that if i create it at runtime in my app if i press the Escapekey in a Multilineeditcontrol, all items,but the description, in the Control are killed, and a heavy exception is fired as soon as the Control losts the Focus o_O. The Returnkey doesnt do anything.
That happens with or without my Pretranslate"hack".
It seems like the behaviour of OnOK and OnCancel, the question is where.
So i think there is anything in the Control who dispatches or translate the Enter and Escape Key to the wrong place, but because no pretranslate is called i dont know where to get in and search for it.
 
The strange is, that the Control in an VisualBasic (6.0) app hasn't that behaviour and functions so as u expect it. Can anyone help ?
