in OnUpdateEvent you use

pCmdUI->SetCheck(..);

Code:

---

        int ind = m_wndToolBar.CommandToIndex(ID_MYCHECKED_BUTTON);
        UINT style = m_wndToolBar.GetButtonStyle( ind ) | TBBS_CHECKBOX ;
        m_wndToolBar.SetButtonStyle(ind, style );

Thanks for the reply , now the same Functionality I have to add in the menu for those buttons,i.e if button A is checked in menu List , in front of menu item a , a chek mark must mbe there,
It is possible if both share the same id
now For setting chek I am using PcmDUI->Setcheck();
But As I have wriiten this in on_update,
the toggling starts on and off ,i.e there is no need to explicitly push the button
kindly help

Create a menu item, and give it the same resource id as for the toolbar button. Also check the 'Checked' property in the menu item.

It's not working

i simply cannot follow you. please try to explain the problem better.
to check/uncheck a menu item use:

Code:

---

void CMainFrame::OnUpdateMenuItem(CCmdUI* pCmdUI)
{
        // TODO: Add your command update UI handler code here
        pCmdUI->SetCheck(TRUE/FALSE);
}

---

there is a button on the toolbar , which do something and toggles, the same work is to be done by a menuitem from the main menu
Now for toggling on Update_command, I have used the above code i.e getButtonStyle and SetButtonStlye
Now the menuitem on menu shares the same id as of button and has the property of checked,now if the button is toggling , simultansly the menu item should bear a check or unchek mark

If I used PCCmd->SetCheck, this is only for handling toolbar buttons as the pointer has the value for CtoolbarCmdUI , and not the value for Cmenu,
So it changes the button value and not the menu item(check , uncheck), though the Id's are Same

for eg
int ind = m_wndToolBar.CommandToIndex(ID_OPTIONS_BAVIEW);
UINT style = m_wndToolBar.GetButtonStyle( ind ) | TBBS_CHECKBOX ;
m_wndToolBar.SetButtonStyle(ind, style );
if(style == 2)
{
PCmdUI->SetCheck(True)
}
I am not able to control my menu item chek , unchek , while the button toggles

this is the prob
I hope now u r having the clear picture
Kindly Help

Declare a boolean variable in your class,

Code:

---

BOOL bState;

---

add a handler to your menu/toolbar click and toogle the value of boolean there

Code:

---

bState = !bState;

---

and in ON_UPDATEUI_XXX hadler just add following

Code:

---

PCmdUI->SetCheck(bState);

hi Amit

but sometimes it's not working
I mean if u have pressed the button down , there is correponding check mark agnst the menu item, vice versa , if u pressed the button up, then again the menu item gets unchek, but if u r doing it frequently , despite u have unpressed the button , a chek mark will be there , i.e the status is not updated b/w the Command handler and the Update_ handler
how could we overcome this problem, I don't want to incorporate
Sleep etc

I hope this is the problem or probably there can be another reason for this .

Kindly suggest
