Declaration:

Declare Function ModifyMenu Lib "user32" Alias "ModifyMenuA" (ByVal hMenu As Long, ByVal nPosition As Long, ByVal wFlags As Long, ByVal wIDNewItem As Long, ByVal lpString As Any) As Long

Parameters:

* hMnu Identifies the menu to be changed. * uPosition Specifies the menu item to be changed, as determined by the uFlags parameter. * uFlags Specifies flags that control the interpretation of the uPosition parameter and the content, appearance, and behavior of the menu item. This parameter must be a combination of one of the following required values and at least one of the values listed in the following Remarks section. MF_BYCOMMAND Indicates that the uPosition parameter gives the identifier of the menu item. The MF_BYCOMMAND flag is the default if neither the MF_BYCOMMAND nor MF_BYPOSITION flag is specified. MF_BYPOSITION Indicates that the uPosition parameter gives the zero-based relative position of the menu item. * uIDNewItem Specifies either the identifier of the modified menu item or, if the uFlags parameter has the MF_POPUP flag set, the handle of the drop-down menu or submenu. * lpNewItem Points to the content of the changed menu item. The interpretation of this parameter depends on whether the uFlags parameter includes the MF_BITMAP, MF_OWNERDRAW, or MF_STRING flag. MF_BITMAP Contains a bitmap handle. MF_OWNERDRAW Contains a 32-bit value supplied by an application that is used to maintain additional data related to the menu item. The value is in the itemData member of the structure pointed to by the lparam parameter of the WM_MEASUREITEM or WM_DRAWITEM messages sent when the menu item is created or its appearance is updated. MF_STRING Contains a pointer to a null-terminated string (the default).
