How to: Get the current Windows taskbar height

Every Windows system has a taskbar. The taskbar height can differ on each computer, even set to auto-hide...
I would like to use OpenWindow() with the height of the screen less the height of the taskbar, so that it is always visible and can be reached.
How can I get the current height setting?
Thanks.

The taskbar can also be in different positions, not necessarily on the bottom of the screen. The way to accomplish your goal is to use SystemParametersInfo_() with #SPI_GETWORKAREA. This will give you the position and size of the desktop excluding the taskbar and you can create your window according to the returned rectangle.

Many thanks Netmaestro. I could find it further on the forum by searching for SystemParametersInfo_.
The solution:
Code: Select all
SystemParametersInfo_(#SPI_GETWORKAREA, 0, @DesktopRect.RECT, 0)
DesktopX = DesktopRect\left
DesktopY = DesktopRect\top
DesktopWidth = DesktopRect\right - DesktopRect\left
DesktopHeight = DesktopRect\bottom - DesktopRect\top
Debug "OpenWindow("+Str(DesktopX)+", "+Str(DesktopY)+", "+Str(DesktopWidth)+", "+Str(DesktopHeight)+")"
Have a good day.

Almost. You have to take into account that a PB window opened to supplied width and height will have a
client area with those dimensions. You'll have to subtract the caption and borders to get what you're looking for:
Code: Select all
SystemParametersInfo_(#SPI_GETWORKAREA, 0, @DesktopRect.RECT, 0)
DesktopX = DesktopRect\left
DesktopY = DesktopRect\top
DesktopWidth = DesktopRect\right - DesktopRect\left
DesktopHeight = DesktopRect\bottom - DesktopRect\top
DesktopWidth-GetSystemMetrics_(#SM_CXFIXEDFRAME)*2
DesktopHeight-(GetSystemMetrics_(#SM_CYCAPTION)+GetSystemMetrics_(#SM_CYFIXEDFRAME)*2)
OpenWindow(0,DesktopX,DesktopY,DesktopWidth,DesktopHeight,"",#PB_Window_SystemMenu)
Repeat:Until WaitWindowEvent()=#PB_Event_CloseWindow
