Checking/Unchecking Menu Items

[Adrian Mongeli]

I need to allow a user to toggle a menu item.. checked on/unchecked off.

How do you code this? Can you provide an example?

Thank you for your assistance.

Hi,
You'll have to handle the UPDATE_COMMAND_UI handler for each of the menu items you want to check or uncheck. Now have a BOOL variable which toggles everytime the user clicks on the menu item in the COMMAND handler of the same menu item. In the UPDATE... handler just use
pCmdUI->SetCheck(YourBool);

An example
I'll declare a variable bCheck as BOOL
In the constructor I'll assign bCheck = FALSE;

CMyClass::OnXXX()
{
bCheck^=1; // This toggles the state;
//do your menu related operations
}
CMyClass::OnUpdateXXX(CCmdUI* pCmdUI)
{
pCmdUI->SetCheck(bCheck);
}
I hope this will help
