把RT控件内容保存到一个BMP或JPG文件中，拜托在帮我看看。不是TRF格式

open事件中用到AW_BLEND可以用setredraw(true)刷新一下

还有不适合sheet，Child窗口

AnimateWindow (Handle ( This ) , 300, 262144 + 65536 + 16 )
写在close事件不好用！？我这里没有问题

不好意思，参数弄错了，现在可以了，不过，关闭时，图象有点拉，有办法让他流畅一些吗？，最后的努力，谢谢斑竹！！

举两个例子

AnimateWindow ( Handle ( This ) , 300, 524288+ 65536 + 16)
AnimateWindow (Handle ( This ) , 300, 262144 + 65536 + 16 )

需要加上AW_CENTER ，AW_HIDE 两个参数

pAnimate a Window
Starting with Win98, a new API is available to add a special effect to your application. The AnimateWindow() is very easy to use, you simply need to pass your window's handle, a delay and some flags to specify the desired effect. These effects are designed to enhance the opening or closing of a window. [local function declaration]
FUNCTION boolean AnimateWindow( long lhWnd, long lTm, long lFlags) &
LIBRARY 'user32'

[instance variable]
CONSTANT LONG AW_HOR_POSITIVE = 1
CONSTANT LONG AW_HOR_NEGATIVE = 2
CONSTANT LONG AW_VER_POSITIVE = 4
CONSTANT LONG AW_VER_NEGATIVE = 8
CONSTANT LONG AW_CENTER = 16
CONSTANT LONG AW_HIDE = 65536
CONSTANT LONG AW_ACTIVATE = 131072
CONSTANT LONG AW_SLIDE = 262144
CONSTANT LONG AW_BLEND = 524288

[powerscript, open event]
// slide right to left
AnimateWindow ( Handle( this ),500,AW_HOR_NEGATIVE)

// slide left to right
AnimateWindow ( Handle( this ),500,AW_HOR_POSITIVE)

// slide top to bottom
AnimateWindow ( Handle( this ),500,AW_VER_POSITIVE)

// slide bottom to top
AnimateWindow ( Handle( this ),500,AW_VER_NEGATIVE)

// from center expand
AnimateWindow ( Handle( this ),500,AW_CENTER)

// reveal diagonnally
AnimateWindow ( Handle( this ),500,AW_VER_NEGATIVE + AW_HOR_NEGATIVE)

Here some notes about the flags (from MSDN) AW_SLIDE Uses slide animation.
By default, roll animation is used.
This flag is ignored when used with the AW_CENTER flag.
AW_ACTIVATE Activates the window. Do not use this flag with AW_HIDE.
AW_BLEND Uses a fade effect.
This flag can be used only if hwnd is a top-level window.
AW_HIDE Hides the window. By default, the window is shown.
AW_CENTER Makes the window appear to collapse inward
if the AW_HIDE flag is used or expand outward
if the AW_HIDE flag is not used.
AW_HOR_POSITIVE Animates the window from left to right.
This flag can be used with roll or slide animation.
It is ignored when used with the AW_CENTER flag.
AW_HOR_NEGATIVE Animates the window from right to left.
This flag can be used with roll or slide animation.
It is ignored when used with the AW_CENTER flag.
AW_VER_POSITIVE Animates the window from top to bottom.
This flag can be used with roll or slide animation.
It is ignored when used with the AW_CENTER flag.
AW_VER_NEGATIVE Animates the window from bottom to top.
This flag can be used with roll or slide animation.
It is ignored when used with the AW_CENTER flag.
