Specify the left, top, width and height variables in the respective properties of the UDT.

Note that WinHelp divides the screen up into units so that both the width and height are 1024 units. The wStructSize should be set so that the API knows how long the structure is. The state contains the desired window state; it is similar to the shell command's windowstyle parameter. The options are:

SW_HIDE	Hides the window and passes activation to another window.
SW_MINIMIZE	Minimises the specified window and activates the top level window in the Z order.
SW_RESTORE	Same as SW_SHOWNORMAL.
SW_SHOW	Activates a window and displays it in its current size and position.
SW_SHOWMAXIMIZED	Activates the window and displays it as a maximised window.
SW_SHOWMINIMIZED	Activates the window and displays it as an icon.
SW_SHOWMINNOACTIVE	Displays the window as an icon. The window that is currently active remains active.
SW_SHOWNA	Displays the window in its current state. The window that is currently active remains active.
SW_SHOWNOACTIVATE	Displays a window in its most recent size and position. The window that is currently active remains active.
SW_SHOWNORMAL	Activates and displays the window. Whether the window is minimised or maximised, Windows restores it to its original size and position.
