I'm trying to make an owner-draw menu in C++ and I'm having a lot of trouble. I'm using MFC's CMenu class and I'm trying InsertMenu();

mymenu->InsertMenu(0, MF_BYPOSITION|MF_OWNERDRAW, ID_RED, "Red");

After doing this, my OnDrawItem function retrieves a DRAWITEMSTRUCT as one of it's argumens and the structure contains a variable called itemData, which is a unsigned integer that contains the fourth parameter of InsertMenu. In my OnDrawItem, I do:

CString data = (LPCTSTR) lpdis->itemData; (lpdis is the DRAWITEMSTRUCT structure).

this works fine if I implement InsertMenu() like above, but when I fill InsertMenu with the fourth parameter being a variable that contains the string I want it to be, it doesn't work. Basically, I need figuring out why this works:

mymenu->InsertMenu(0, MF_BYPOSITION|MF_OWNERDRAW, ID_RED, "Red");

and not this:

CString red = "red";
mymenu->InsertMenu(0, MF_BYPOSITION|MF_OWNERDRAW, ID_RED, red);

If you have any hints or suggestions, please help me.

I don't program in MFC, but I know a little of. Try this:

CString red = "red";
mymenu->InsertMenu(0, MF_BYPOSITION | MF_OWNERDRAW, ID_RED, (LPCTSTR)red);

Or this:

CString red = "red";
mymenu->InsertMenu(0, MF_BYPOSITION | MF_OWNERDRAW, ID_RED, (LPTSTR)red);

There's only a capital C of difference, but may help...
