I am using the code snippet below in a dialog based application(MFC) to get dynamic menu items.

pMenu->LoadMenu(IDR_MENU1);
pMenu->AppendMenu(MF_STRING | MF_ENABLED, /*cmdID*/ 50001, "New Item");

It throws no errors but doing nothing. i.e. No new menuitem is appended to the existing menu. Can anybody help me. I'll be extremely thankful. And How can i catch the COMMAND messages for newly created menu items ??.

I have implemented the OnInitMenuPopup() also  (as said in www.support.microsoft.com/support/kb/articles/Q242/5/77.asp ) to test if it has any effect, but Nothing happened.

Please help to sort out these problems...

with Regards
Reghunath.

IDR_MANU1 is the main menu

if u want to add a menu item in any of these menu bar items, u have to select its submenu first

the code look like this

     CMenu menu;
     CMenu* pPopup;

     // the font popup is stored in a resource
     menu.LoadMenu(IDR_MENU1);
     pMenu = menu.GetSubMenu(0);
     pMenu->AppendMenu(MF_STRING | MF_ENABLED, /*cmdID*/ 50001, "New Item");


GOOD LUCK

Hi Roshmon
Thankyoo for responding to my question.
Actually, I tried that too, But failed.

As i am lucky enough to get a code snippet from www.codeguru.com/dialog/OnUpdate.shtml..to implement the WM_KICKIDLE message. It works fine. But the problem now is, how to catch messages for the new menu items created. Can u spend some of ur valueable time to sort these out.

With Regards

Use macro

ON_COMMAND_RANGE
instead of
ON_COMMAND

u can specify a range of ids that u created dynamically
