Thread: using GDI to draw round ended line

I would like to draw round ended lines using GDI but the below solution doesnt works.
My Compiler doesn't recognize PS_ENDCAP_ROUND and ExtCreatePen.

Code:

        LOGBRUSH lBrush;
	DWORD pStyle = PS_GEOMETRIC | PS_ENDCAP_ROUND;
        DWORD pWidth = 16;

	lBrush.lbStyle = BS_SOLID;
        lBrush.lbColor = RGB(0,0,0);
       lBrush.lbHatch = 0;
	HPEN hPen = ExtCreatePen(pStyle, pWidth, &lBrush, NULL, NULL);
	OldHPen = (HPEN)SelectObject(DrawingBuffer,hPen)

Can anyone point out what I have miss out here? Thanks.

check in your compiler's include directory if PS_ENDCAP_ROUND exists. If not, you might have an old compiler or incorrect library. if it does there might be some #ifdef's around it.
What compiler you using anyway? I see on MSVC6 (which is pretty old) that it has existed for a long time

I am using visual studio 2005
I found out that the compiler's include directory for my app does not define the PS_ENDCAP_ROUND. (C:\Program Files\Microsoft Visual Studio 8\SmartDevices\SDK\PocketPC2003\Include\wingdi.h)

On the other hand, I found that it is defined in C:\Program Files\Microsoft Visual Studio 8\VC\PlatformSDK\Include\WinGDI.h

Does it mean that pocketPC cannot use PS_ENDCAP_ROUND? Thanks.

Thanks Salem.
Actually, i need the round ended option to fix some broken lines of my app.
The n points line is form by n-1 segments where the joining appears broken when i increase the pen thickness. My another attempt was to draw eclipse at the line end but not successful.
I am using the MoveToEx() and LineTo() function.
Besides Polygonline, is there other methods to solve this problem? thanks.

btw, next time search google for "PS_ENDCAP_ROUND windows CE" or something. First hit would've told you. And specify what compiler and platform you use immediately if you think it could be related to that
