传递数据的问题

[gold112y]

想把当前窗口中的datawindow的数据复制到另一窗口的datawindow中
如：
dw_1.rowsmove(dw_1.getrow(),dw_1.getrow(),primary!,w_temp.dw_2,1,primary!)
w_temp.dw_2.setitemstatus(1,0,primary!,newmodified!)

提示错误，应怎么写?

dwcontrol The name of a DataWindow control, DataStore, or child DataWindow from which you want to move rows
startrow The number of the first row you want to move
endrow The number of the last row you want to move
movebuffer A value of the dwBuffer enumerated data type (PowerBuilder) or an integer (Web ActiveX and Java) identifying the DataWindow buffer from which you want to move the rowsFor a list of valid values, see DWBuffer
targetdw The name of the DataWindow control or DataStore to which you want to move the rows. Targetdw can be the same DataWindow control (or DataStore) or a different DataWindow control (or DataStore), but it cannot be a child DataWindow
beforerow The number of the row before which you want to insert the moved rows. To insert after the last row, use any value that is greater than the number of existing rows
targetbuffer A value of the dwBuffer enumerated data type (PowerBuilder) or an integer (Web ActiveX and Java) identifying the target buffer for the rowsFor a list of valid values, see DWBuffer

dw_1.RowsCopy(dw_1.GetRow(), &

dw_1.RowCount(), Primary!, dw_2, 1, Primary!)

提示什么错误?
还没试过在两个窗口中移数据，在同一个窗口中没问题

[bbdx2523]

在一个窗口中操作另一个窗口的对象，要先在窗口1中声明一个window 变量，再把另一个窗口通过messsage对象传递过来，然后关联到window变量上，再操作。
你现在是对窗口2的dw进行操作，建议把dw_2引用过来就好了。

试试 bbdx2523(模二战士) 的方法把！记住要在第二个窗体操作，也就是要接受数据的窗口
