This message sets the information that a ToolTip control maintains for a tool.

Syntax 

TTM_SETTOOLINFO 
wParam = 0;

lParam = (LPARAM) (LPTOOLINFO) 
lpti;

Parameters

wParam

Not used. Set to 0.

lpti

Pointer to a TOOLINFOstructure that specifies the information to set. You must set the cbSizemember of this structure before you send this message.

Return Value

None.

Remarks

Some internal properties of a tool are established when you create the tool and are not recomputed when you send a TTM_SETTOOLINFO message. If you simply assign values to a TOOLINFOstructure and pass that structure to the ToolTip control in a TTM_SETTOOLINFO message, these values can be lost. Instead, your application should first request the current TOOLINFOstructure for the tool by sending the ToolTip control a TTM_GETTOOLINFOmessage. Then, modify the members of the current TOOLINFOstructure as needed and pass that structure back to the ToolTip control with TTM_SETTOOLINFO.

Requirements

Header commctrl.h
Windows Embedded CE Windows CE .NET 4.0 and later
Windows Mobile Windows Mobile Version 5.0 and later
