I have some problems with LoadCommandBars and my own XTPControlButton's.

I my own class CControlVarMenu derived from CXTPControlButton. In OnCreateControl I create my objects:

if(lpCreateControl->nID == ID_POPUP_SEND)
{
lpCreateControl->pControl = new CControlVarMenu(&m_MenuEntries, VM_SEND);
return TRUE;
}

You see the 2 parameters in the constructor.

All work very well until the user makes a customization of the toolbar. After
LoadCommandBars the constructor of my objects is now called with NULL in the
parameter (without calling OnCreateControl).
When the button on the toolbar is pressed, the member variables of my button
objects are not set!

What is the correct way to set the member variables of my CXTPControlButton
object after a LoadCommandBars?

thank you

Hello, you have to override void DoPropExchange and Copy methods and implement save/restore logic for your control.

Hi, thx for help

I Have already overwritten the Copy method.

The DoPropExchange method is not interresing for me, because i have no static information to store. I have only dynamical information (for example in the posted source: "m_MenuEntries" is a collection of objects of inserted USB sticks).

Should i go through the tollbar buttons, and set the members with a new function?

Hello,

If m_MenuEntries is dynamic menu, you can fill items before user popup menu with these items.

See source of Samples\CommandBars\DynamicPopups\ControlUndo.cpp how to fill items dynamically before they become visible.
