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.
Can anyone point out what I have miss out here? Thanks.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)
Should be in the Windows board.
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
Read the manual, figure out what is and isn't allowed, and then figure out an answer.
Eg. work out the "round endcaps" algorithm yourself and draw them.
