The TB_SETROWS message sets the number of rows of buttons in a toolbar.

TB_SETROWS

wParam = (WPARAM) MAKEWPARAM(cRows, fLarger);

lParam = (LPARAM) (LPRECT) lprc;

Parameters
cRows
Number of rows requested. The minimum number of rows is one, and the maximum is equal to the number of buttons in the toolbar.

fLarger
Flag that indicates whether to create more rows than requested when the system cannot create the number of rows specified by cRows. If this parameter is TRUE, the system creates more rows. If it is FALSE, the system creates fewer rows.

lprc
Pointer to a RECT structure that receives the bounding rectangle of the toolbar after the rows are set.

Return Values
No return value.

Remarks
Because the system does not break up button groups when setting the number of rows, the resulting number of rows might differ from the number requested.
