Thread: Help with MenuHelp

Hi,

I want to use a status bar in my program to display information about each of the menu commands available, and apparently MenuHelp can do this. It appears to be best used inside a WindowProc, when the WM_MENUSELECT message is processed. However, I'm not sure how the array of the menu handle/string resource ID pairs is structured. Any ideas?

At a guess:

From fn description:
"Address of an array that contains pairs of string resource identifiers and menu handles.":

eg if you have 3 menu items previously designed in a resource script and a 'descriptor' string for each menu item in a string table in a resource script:

UINT nResID[6];
nResID[0]=IDS_MENU1; //id of string resource 1
nResID[1]=IDM_MENU1; //id of menu item resource 1
nResID[2]=IDS_MENU2; //id of string resource 2
nResID[3]=IDM_MENU2; //id of menu item resource 2
nResID[4]=IDS_MENU3; //id of string resource 3
nResID[5]=IDM_MENU3; //id of menu item resource 3

And pass address of nResID as last param of fn. I'd be curious to know if that works as i've never used that fn before.

Well, after consulting Mr. Petzold, I used the function like so:-

Code:

HINSTANCE gInstance; //set at startup
HWND hStatus; //status bar window
UINT uiMenuHelpID = 0;

(in "case WM_MENUSELECT:" in WindowProc)
MenuHelp(uMsg, wParam, lParam, NULL, gInstance, hStatus, &uiMenuHelpID);

This works very well, I made made a string table with the IDs equal to the menu item IDs and they are displayed correctly!
