a common error message please!

I get this message lots of time when I am playing around with the API functions:


code]
error C2664: 'SetMenuDefaultItem' : cannot convert parameter 2 from 'struct HMENU__ *' to 'unsigned int'
This conversion requires a reinterpret_cast, a C-style cast or function-style cast
[/code]


I get this error lots of times when I am working with the menus and backgrounds...stuff like that

Here is an example of problem that I am having:;

----------------------------------------------------------------------------

I want to make a menu item bold by first selecting a handle to the main menu and then getting a handle to the sub menu. I am using this code to do that but I am getting the above error message:

SetMenuDefaultItem(hmenu, GetSubMenu(hmenu, 0), true);


I have defined hemnu as HMENU (it is a global variable)

Can you please tell me why it is happening and how do I get rid of that erroe message that I often get.

Try this:

Code:

---


SetMenuDefaultItem(hMenu, PositionOfItemToBeDefaulted, true);

---

It's because of something called strict mode. :rolleyes:
As the message says, you'll need to use cast.
For example:

Code:

---

// Instead of:
SelectObject(MyHDC, MyBrush);

// Use:
SelectObject(MyHDC, (HGDIOBJ)MyBrush);

---

This might also occur on the return value:

Code:

---

// Instead of:
OldBrush = SelectObject(MyHDC, (HGDIOBJ)MyBrush);

// Use:
OldBrush = (HBRUSH)SelectObject(MyHDC, (HGDIOBJ)MyBrush);

---

Code:

---

SetMenuDefaultItem(hMenu, PositionOfItemToBeDefaulted, true);

---

That does not worky properly. When I put 0, it makes the file menu (just the first header menu) bold. And when I try 1, it does not make the sub menu bold.

I've never used it before, so I'm not quite sure, but I think you have to do this.

Code:

---

SetMenuDefaultItem(hSubMenu, PositionOfItemToBeDefaulted, true);

---

It works now.
Just another question:

How do I know the menuitem postion and the submenu item position when the mouse moves over it.
