treeview取数问题
<P>以下代码是想实现从库里取数,一个一个加到树型里.可是不知要怎么来判断,下级的所属上级是某一个.<BR><BR>int i,j<BR>datastore d_stroe_1 //定义数据存储对象<BR>d_stroe_1=create datastore<BR>d_stroe_1.dataobject="d_treeview"<BR>d_stroe_1.settransobject(sqlca)<BR>d_stroe_1.retrieve()<BR>i=d_stroe_1.rowcount()</P><P>long ll_lev1,ll_lev2</P>
<P>treeviewitem ltv_new,ltv_old<BR>getitem(handle,ltv_old)<BR>for j=1 to i<BR> aa=d_stroe_1.getitemstring(j,"czybh")<BR> bb=d_stroe_1.getitemstring(j,"czy")<BR> cc=d_stroe_1.getitemstring(j,"czyjb")<BR> ltv_new.data=trim(aa)<BR> ltv_new.label=trim(bb)<BR> ltv_new.pictureindex=1<BR> ltv_new.selectedpictureindex=6<BR> ltv_new.children=true<BR> ltv_new.level=integer(trim(cc))<BR> <BR>if left(aa,3)=left("czybh",3) then<BR> <BR> if ltv_new.level=1 then<BR> ll_lev1=tv_1.insertitemlast(0,aa,1)<BR> else <BR> <BR> ll_lev2=tv_1.insertitemlast(ll_lev1,aa,2)<BR> end if<BR> <BR>end if<BR>next</P>
