我想自己创建一个自定义画刷，为什么下面的代码不对呢，大家改一下，不用现成的位图

[sulong1234]

BITMAP bitmap;
COLORREF PATTEN[8][8]={
RGB(0 ,255,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ),
RGB(0 ,0 ,0 ), RGB(0 ,255,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ),
RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,255,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ),
RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,255,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ),
RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,255,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ),
RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,255,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ),
RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(255,0 ,0 ), RGB(0 ,0 ,0 ),
RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(255,0 ,0 )};
bitmap.bmType = 19778;

bitmap.bmWidth = 8;
bitmap.bmHeight = 8;
bitmap.bmWidthBytes = 8;
bitmap.bmPlanes = 1;
bitmap.bmBitsPixel = 24;
bitmap.bmBits = (LPVOID)PATTEN;
HBITMAP hb = CreateBitmapIndirect(&bitmap);

HDC dc = GetDC(hwnd);

//HBRUSH hr= CreateSolidBrush(RGB(255,0,0));//CreatePatternBrush(hb);
SelectObject(dc, CreateSolidBrush(RGB(255,0,0)));
Rectangle(dc, 0, 0, 300, 300);
HBRUSH hr= CreatePatternBrush(hb);
HGDIOBJ gdi = SelectObject(dc, hr);
Rectangle(dc, 300, 300, 600, 600);

HDC dc = GetDC(hwnd);//能得到么?得不到后面得操作就是全部免谈

bitmap.bmWidthBytes = 8; ==> 8 * sizeof(COLORREF)

bitmap.bmBitsPixel = 24; ==> 32

[xing_xing_xing]

CreateBitmapIndirect创建设备无关位图
如果是当前颜色深度是24位
bitmap.bmWidthBytes = 8 * 3;
如果是16位
bitmap.bmWidthBytes = 8 * 2;
bitmap.bmBitsPixel = 16;
32位就是楼上的

要通用可以使用CreateDIBitmap

按上面的说明还是不对，画刷是一个白的

CPaintDC dc(this)
COLORREF pBits[8][8]={
RGB(0 ,255,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ),
RGB(0 ,0 ,0 ), RGB(0 ,255,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ),
RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,255,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ),
RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,255,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ),
RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,255,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ),
RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,255,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ),
RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(255,0 ,0 ), RGB(0 ,0 ,0 ),
RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(0 ,0 ,0 ), RGB(255,0 ,0 )};
BITMAP bitmap = {0};
bitmap.bmType = 0;
bitmap.bmWidth = 8;
bitmap.bmHeight = 8;
bitmap.bmWidthBytes = 8 * sizeof(COLORREF);
bitmap.bmPlanes = 1;
bitmap.bmBitsPixel = 32;
bitmap.bmBits = (LPVOID)pBits;

HBITMAP ht = ::CreateBitmapIndirect(&bitmap);
if (ht)
{
HBRUSH hbr = ::CreatePatternBrush(ht);
HBRUSH hbrOld = (HBRUSH)dc.SelectObject(hbr);
dc.Rectangle(0, 0, 100, 100);
dc.SelectObject(hbrOld);
::DeleteObject(hbr);
::DeleteObject(ht);
}
这是在对话框中OnPaint()里试的，完全可以
对了，注意：
bmType
Specifies the bitmap type. This member must be zero.

黑地绿色斜线

楼上的,你看到的是什么结果？？？？
我看到的是白色的画刷填充的，而不是我自已定义的刷

[菜牛]

我这个代码是在对话框中试验过的，绝对没有问题。请仔细再检查一下。
