现已实现在表单上画出,本来想画到图片中再通过透明窗口来实现,试了一下字体边缘很难看....
主要是这两个API不知道怎么实现
CreateDIBSection
UpdateLayeredWindow
网上找到的CreateDIBSection定义但BHDR_STRUCT_SIZE参数的值不知道是什么
nBitmapWidth=500
nBitmapHeight=300
nBitsPerPixel=24
ppvBits=0
cBITMAPINFOHEADER=num2dword(BHDR_STRUCT_SIZE) +;
num2dword(nBitmapWidth) + num2dword(nBitmapHeight) +;
num2word(1) + num2word(nBitsPerPixel) +;
num2dword(BI_RGB)

BHDR_STRUCT_SIZE, CHR(20))
hBitmap=CreateDIBSection(hDC, @cBITMAPINFOHEADER,;

以下代码放在一个命令按键里就可看出绘制效果,注意表单的ShowWindow=0

这个真的可以实现, 只是稍有点麻烦, 没时间了, 算我路过得了! 呵呵呵, 抱歉!

另外有时候会窗口什么都不显示(不是每次都能成功显示),手工调用Paint后就显示了
不知道是不是VFP窗口本身的问题....

嗯,是参数传错了应该是MDC
已经实现,将以下代码放入表单的Paint事件,表单设置为顶层表单
呵呵,这个效果和生成图片的效果一样(黑边),最后参数为1的效果就是这样(VB里也是)
现在的问题是当UpdateLayeredWindow的最后一个参数为2时倒数第二个参数到底是怎么设置的
晕哦......

已经实现,将以下代码放入表单的Paint事件,表单设置为顶层表单
呵呵,这个效果和生成图片的效果一样(黑边),最后参数为1的效果就是这样(VB里也是)
现在的问题是当UpdateLayeredWindow的最后一个参数为2时倒数第二个参数到底是怎么设置的
晕哦......

粗粗看了一下，返回2是因为 api 声明和调用有误造成，第二个参数应该传引用：
Declare Long GdipCreateFromHDC IN gdiplus Long, Long @
相应的调用语句也要加 @
GdipCreateFromHDC(hDC, @ graphics)
此外，按照你的说明将表单 ShowWindow 设为 2，则应该取内里窗口的 hWnd，在最前面加下列语句，然后将所有的 Thisfrom.hWnd 替换为这个 hh：
DECLARE Long FindWindowEx IN WIN32API Long,Long,Long,Long
hh = FindWindowEx(Thisform.hwnd, 0, 0, 0)
如果 ShowWindow 不为 2，且 ScrollBars 为缺省值 0，则不需要修改
应该还有很多错误，自己检查吧

嗯,问题在GdipCreateFromHDC(hDC, graphics)

其实也不算复杂,就是代码太乱了
关键就在这段VB代码,其它都是绘制文字的
mDC = CreateCompatibleDC(Me.hdc)
mainBitmap = CreateDIBSection(mDC, tempBI, DIB_RGB_COLORS, ByVal 0, 0, 0)
oldBitmap = SelectObject(mDC, mainBitmap)
Call GdipCreateFromHDC(mDC, graphics)
curWinLong = GetWindowLong(Me.hwnd, GWL_EXSTYLE)
SetWindowLong Me.hwnd, GWL_EXSTYLE, curWinLong Or WS_EX_LAYERED
srcPoint.X = 0
srcPoint.Y = 0
winSize.cx = Me.ScaleWidth
winSize.cy = Me.ScaleHeight
With blendFunc32bpp
.AlphaFormat = AC_SRC_ALPHA
.BlendFlags = 0
.BlendOp = AC_SRC_OVER

End With

感觉就要实现了,可不知道为什么显示不出东西,我想问题应该在最后一步
想要调试却不知道如何将graphics保存到图片,这样至少知道绘制结果是否正常
