long lstructsize
ulong hwndowner
ulong hinstance
long rgbresult
blob lpcustcolors
long flags
long lcustdata
long lpfnhook
long lptemplatename
定义例子变量:
Private:
os_ChooseColor istr_ChooseColor
long il_CustomInitColors[16]
blob{64} ibl_CustomColors
定义外部::
function boolean ChooseColorA( REF os_ChooseColor lpcc ) library "comdlg32.dll"
在 constructor 事件中写入如下代码::
// initialize choosecolor information
// convert the default custom color .gif' /> to a blob variable blobedit(ibl_customcolors,1,il_custominitcolors)
// let the structure element po to the blob .gif' />
istr_choosecolor.lpcustcolors = ibl_customcolors
// the size
istr_choosecolor.lStructSize = 36
// no owner
SetNull(istr_choosecolor.hwndOwner)
// flag
istr_choosecolor.flags = 1
创建对象:boolean of_choosecolor(ref long al_rgbresult) ,代码如下:
boolean lb_ok
istr_ChooseColor.rgbresult = al_rgbresult
lb_ok = ChooseColorA ( istr_choosecolor )
al_rgbresult = istr_ChooseColor.rgbresult
lb_ok
