vb.net - How to remove dynamically created controls? -

i've added few pictureboxes form with:

at top of code:

private flag picturebox 

under form1_load event:

flag.location = new point(buttonx, buttony)                         flag.backcolor = color.red                         flag.borderstyle = borderstyle.fixedsingle                         flag.name = "flag" & pos                         me.tabpage1.controls.add(flag)                         flag.bringtofront() 

so end with, example, 4 pictureboxes named "flag2" "flag5" "flag6" "flag8". try remove them with:

dim con control         each con in me.tabpage1.controls             if con.name.contains("flag")                 me.tabpage1.controls.remove(con)             end if         next 

what ends happening not pictureboxes deleted. if run delete code multiple times rid of them i'm trying remove them @ once. tried:

dim con control         dim integer = 0         while < me.tabpage1.controls.count             con = me.tabpage1.controls(i)             if con.name.contains("flag")                 me.tabpage1.controls.remove(con)             end if             += 1         end while 

both "delete codes" delete picture boxes in same order each other (not in order created way) instead of deleting of picture boxes.

try this:

'create pbs delete dim pbs = me.tabpage1.controls.oftype(of picturebox)().              where(function(pb) pb.name.contains("flag")) 'loop thru them each pb in pbs   me.tabpage1.controls.remove(pb) next  

sub:

public sub removepictureboxes(tp tabpage)   'create pbs delete   dim pbs = tp.controls.oftype(of picturebox)().              where(function(pb) pb.name.contains("flag"))   'loop thru them   each pb in pbs     tp.controls.remove(pb)   next   end sub 

usage:

removepictureboxes(tabpage1)
