[Closed] DotNet controls Picture Box

This also works…

try(destroydialog dlg) catch()
 rollout dlg "" 
 (
  dotNetControl flp "flowlayoutpanel" height:60
  
  fn whenButtonClick s e = (format "\"%\" clicked
" s.text)
  fn makeButtons = for k=1 to 2 collect 
  (
   btn = dotnetobject "button"
   btn.text = "Layout B" + (k as string)
   dotNet.addEventHandler btn "click" whenButtonClick
   dotNet.setLifetimeControl btn #dotnet
   btn
  )
  on dlg open do
  (
   local buttons = makeButtons()
   flp.controls.addrange buttons
  )
 )
 createdialog dlg

And so you don’t have to search for the difference, I’ll just tell you. Look up dotNet.setLifetimeControl in the help doc. This was added in 2010 specifically to fix this problem. Setting the lifetime control to #dotnet mean that the even handlers don’t get garbage collected by Max.
