کدهایی که زدم اینان

Sub Activity_Create(FirstTime As Boolean)
Activity.LoadLayout(“frm_food_info”)

Main.cur=Main.sql.ExecQuery(“SELECT * FROM tbl_ashpazi2 WHERE id=”&id2)
Main.cur.Position=id2

lbl_onvan.Text=Main.cur.GetString(“foodname”)

Dim lbl_txt_info As Label
lbl_txt_info.Initialize(“lbl_txt_info”)
slv_food_info.Panel.AddView(lbl_txt_info,0,0,100%x,100%y)
lbl_txt_info.Text=Main.cur.GetString(“foodtext”)
Dim stu As StringUtils
lbl_txt_info.Height=stu.MeasureMultilineTextHeight(lbl_txt_info,lbl_txt_info.Text)
slv_food_info.Panel.Height=lbl_txt_info.Height
End Sub

خط ۲۶ هم اینه

lbl_onvan.Text=Main.cur.GetString(“foodname”)
