如何在数据窗口中找到最大的TAB值

[prince022]

如何在数据窗口中找到最大的TAB值，取到最大的TAB值按tab键or Enter键返回1，因为一般情况下按TAB值按tab键or Enter键它会跳到下一条纪录,求助!!!!!

for ll_row = 1 to Integer(this.Describe("DataWindow.Column.Count"))
ls_cname = this.Describe("#" + String(ll_row) + ".Name")

if this.Describe(ls_cname + ".Visible") <> "0" then
// Get first and last column
if this.Describe(ls_cname + ".Protect") = "0" then
if ll_firstcol = 0 or Long(this.Describe(ls_cname + ".TabSequence")) < ll_firstcol then
ll_firstcol = Long(this.Describe(ls_cname + ".TabSequence"))
ls_firstcol = ls_cname
end if
if ll_lastcol = 0 or Long(this.Describe(ls_cname + ".TabSequence")) > ll_lastcol then
ll_lastcol = Long(this.Describe(ls_cname + ".TabSequence"))
ls_lastcol = ls_cname
end if
end if
end if
