sorry,你是要"该"改啊...我还以为要读呢.
做一个自适应屏幕分辨率的窗口,当成一个应用程序中所有窗体的基类。这样整个程序可以很好的适应屏幕分辨率的改变。实现的原理很简单,就是在窗口打开的时候去RESIZE窗口和窗口中的控件大小,位置。参看下面的源代码,可以很容易的看懂。
1。新建一个窗口。
为窗口写一个函数f_resize()大部分工作就在这里。
无输入参数
返回值为整形:
environment env
integer ii_ScreenWidth,ii_ScreenHeight
double WRadio,HRadio,Radio
integer ii_WinBolderWidth,ii_WinBolderHeight
getenvironment(env)
ii_WinBolderWidth=this.width - this.WorkSpaceWidth()//取得窗体的边框宽度
ii_WinBolderHeight=this.height - this.WorkSpaceHeight()
ii_ScreenWidth=env.screenwidth
ii_ScreenHeight=env.screenheight
//compute the radio that need be resize
WRadio=ii_ScreenWidth/800 //标准认为屏幕分辨率为800*600
HRadio=ii_ScreenHeight/600//计算出屏幕相对800*600分辨率的变化量
Radio=Min(WRadio,HRadio)
if Radio=1.0 then //if the screen is default 800*600
return 0
end if
this.hide()
this.width=(this.width - ii_WinBolderWidth)*Radio + ii_WinBolderWidth
this.height=(this.height - ii_WinBolderHeight)*Radio + ii_WinBolderHeight
integer i
dragobject temp//用于取各种控件
for i=1 to upperbound(this.control)
temp=this.control[i]//调整大小,位置
temp.width=temp.width*Radio
temp.x=temp.x*Radio
temp.y=temp.y*Radio
temp.Height=temp.Height*Radio
choose case typeof(temp)
case tab!
tab mtab
mtab=temp
mtab.textsize = mtab.textsize*Radio//设置字体
case commandbutton!
commandbutton cb
cb = temp
cb.textsize = cb.textsize*Radio
case singlelineedit!
singlelineedit sle
sle = temp
sle.textsize=sle.textsize*Radio
case editmask!
editmask em
em = temp
em.textsize = em.textsize*Radio
case statictext!
statictext st
st = temp
st.textsize = st.textsize*Radio
case datawindow! // datawindows get zoomed
datawindow dw
dw = temp
dw.Object.DataWindow.zoom = string(int(Radio*100))//注意DATAWINDOW与其它控件的不同
case picturebutton!
picturebutton pb
pb = temp
pb.textsize = pb.textsize*Radio
case checkbox!
checkbox cbx
cbx = temp
cbx.textsize = cbx.textsize*Radio
case dropdownlistbox!
dropdownlistbox ddlb
ddlb = temp
ddlb.textsize = ddlb.textsize*Radio
case groupbox!
groupbox gb
gb = temp
gb.textsize = gb.textsize*Radio
case listbox!
listbox lb
lb = temp
lb.textsize = lb.textsize*Radio
case multilineedit!
multilineedit mle
mle = temp
mle.textsize = mle.textsize*Radio
case radiobutton!
radiobutton rb
rb = temp
rb.textsize = rb.textsize*Radio
end choose
next
this.show()
return 0
函数写好以后,在窗体的OPEN事件里调用该函数即可.

有这个更改分辨率的dll可以在www.pbdrive.com中找到,但是不能更改刷新率。Top

试试这个
Global External Function:
FUNCTION ulong GetPixel(ulong hwnd, long xpos, long ypos) LIBRARY "Gdi32.dll"
FUNCTION ulong SetPixel(ulong hwnd, long xpos, long ypos, ulong pcol) LIBRARY "Gdi32.dll"
Script:
long lx, ly
ulong rtn
ulong l_handle, l_device
lx = 100
ly = 100
l_handle = handle(w_main)
l_device = GetDC(l_handle)
rtn = GetPixel(l_device, 100, 100)
MessageBox("Position " + string(lx) + "," + string(ly),"Color = " + string(rtn))
SetPixel(l_device, lx, ly, 0) // This call will set the pixel at lx, ly to black.Top
