CPen question

Is it possible to create a CPen using the PS_USERSTYLE style under MS Windows 9.x? I tried it but nothing appeared n the screen.

Thanks.

Hi,

PS_USERSTYLE is supported only on Windows NT/2000/XP. I dont think, u achive that on a 9x system.

Go to following link
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/gdi/pens_6rse.asp

They have not listed the 9x as the supporting OS for that style.

So, better think of some other way to achive ur targets.

Interesting but I could not find too much information about this function. Does it work for curve lines? Could yo send a little example? I'll double the amount of points I offer.

Thank.

Hi!
no it doesn`t work for curve
here is example how to draw true dotted line

struct LINEDDAPARAM
{
HDC hDC;
bool bSet;
};

static void __stdcall LineDDAProc( int x, int y, LPARAM lParam)
{
LINEDDAPARAM *pParam = (LINEDDAPARAM*)lParam;
if( pParam->bSet)
SetPixelV( pParam->hDC, x, y, SYS_COLOR_LINES);
pParam->bSet = !pParam->bSet;
}

// and how to use

{
// some drawing code...
LINEDDAPARAM ddaParam;
ddaParam.hDC = hDC;
ddaParam.bSet = false;
LineDDA(0, 0, 100, 100, LineDDAProc, (LPARAM)&ddaParam);
}

Hmm I think this code displays a pixel every time, right?

Because it does not work for curve lines. What's the matter?
