SHCreateMenuBar (Windows CE 5.0)

Artigo
09/14/2012

This function creates a menu or softkey bar, as appropriate, to be associated with a specified window.

Syntax

BOOL SHCreateMenuBar(  SHMENUBARINFO * pmb);

Parameters

pmb
[in] Pointer to an SHMENUBARINFO structure.

Return Values

This function returns TRUE if it is successful and FALSE if it fails.

Remarks

When successful, the newly created menu bar or soft key bar is positioned at the bottom of the specified window.

An application must resize its main window to accommodate the size of the menu bar. The following code shows how to programmatically determine the size of the menu bar.

hMenuBar = SHFindMenuBar( MyMainWindow);
GetWindowRect(hMenuBar, &MyRect);

Windows Mobile Remarks

In Windows Mobile 5.0, a soft key bar will be automatically created if the specification passed to SHCreateMenuBar function contains 2 or less top level menu items and those menu items do not contain images.

If the specification passed to SHCreateMenuBar function contains images or more than 2 top level menu items, the behavior is as follows.

SHCreateMenuBar will fail for a Windows Mobile 5.0-based Smartphone
SHCreateMenuBar will create a traditional style menu bar for a Windows Mobile 5.0-based Pocket PC

                if (VK_SPACE == wParam)
                {

                    if(fDisableSK)

                        SHEnableSoftkey(g_hwndMb, /*uid*, 0 for SK1, 1 for SK2*/1, /*bByIndex*/TRUE, TRUE);
                    }

                    }

                }
                break;
