Anyone know how to calculate the height of the taskbar and where the taskbar is docked?

Hi Carlo,

I looked into this and found two approaches using API, have a look for yourself:
[www.codeguru.com]
[forums.devx.com]

I would go the easy way: First maximize a window for a short moment and find out position of the upper left corner and its dimensions, next resize and reposition it it to its original size & position. Now, the size of the maximized window is the size of the client area, its upper left corner ( x<>0 or y<>0 ) position tells you whether the task bar is docked left or on top of screen. Then use SysMetric( .. ) to find out the actual scren size pixel x pixel. Now it should be easy to tell whether the task bar is docked on bottom or right of the screen. Subtracting the Window size from the screen size reveals the size of the task bar.

Hi Everybody...

I didn't test, but I'm wondering what the result of this method will be on a system where the taskbar is autohiding?

Best regards

Hi Fabrice, yes, that's a drawback, because if you're starting an application while TaskBarAutoHideON = True you would get windowsize = size of client area, thus one couldn't locate the docking position of the task bar. However, I do not see the purpose of Carlo's question in the first place ... why would he want to know the size of the task bar?Maybe, he could shed some light on it.

Guenter and Fabrice,

Well I am not great with API, but I try. I have a little bit problems to address the rect structure.

Why do I need the height? Because I want to create a popup screen (msn/outlook style) on top of the taskbar. I now am creating one in the center (hor.) at the top of the screen pulling down, but I like one on top of the taskbar.

This is why I need the height and I need the docked location.

BTW,

Any help on how to work with these would be apriciated.

FunctionResult is boolean // C Type:BOOL
hWnd is int // C Type:HWND
lpRect is int // Pointer on structureRECT

FunctionResult=API("USER32","GetWindowRect",hWnd,lpRect)


RECT is structure
left is int //Type C : LONG
top is int //Type C : LONG
right is int //Type C : LONG
bottom is int //Type C : LONG
END

Have you tried SYSICON* instructions ?

Paulo,

Could you please explain?

I looked at the sysicon features but cannot find where the functions are for the height of the taskbar and where it is docked.

Regards,
Carlo

Hi,

Api to get height (...) of taskbar

Init

RECT is structure
	nLeft is int
	nTop is int
	nRight is int
	nBottom is int	
END

APPBARDATA is structure
	nCbSize is int
	nHwnd is int
	nUCallbackMessage is int
	nUEdge is int
	APBRECT is RECT
	nLParam is int			
END

ABM_GETTASKBARPOS is int = 0x5//&H5

Get height taskbar

ABD is APPBARDATA
API("SHELL32.DLL","SHAppBarMessage",ABM_GETTASKBARPOS,&ABD)

//Trace("right "+abd:APBRECT:nRight)
//Trace("left "+ABD:APBRECT:nleft)
//Trace("top "+ABD:APBRECT:ntop)
//Trace("bottom "+ABD:APBRECT:nBottom)
Trace("height "+(ABD:APBRECT:nBottom-ABD:APBRECT:nTop))

Thanks this is working great, with left,right,top,bottom I can als see where it is docked. Just follow the zero's .

Now I am playing with the autohide settings.

Thank you very much.
