vb.net - how to keep the selected checkbox when the form is close? -

-

i got checkbox , want retain selected ones when reopen form. here's done returns first selected checkbox only..

for each stritm string in str         each ctl control in me.controls             if typeof ctl checkbox                 if ctl.text = stritm                     dim cb checkbox = directcast(ctl, checkbox)                     cb.checked = true                 end if             end if         next     next

and me out. tnx in advance. more power.

an easy way create global bool variable each check box holds true when check box checked , false when it's not. when close form variables keep values. once re-open form can set checked property matching variables through form load event 

private sub frmmain_load(sender object, e eventargs) handles mybase.load     checkbo1.checked = globalvar1     checkbo2.checked = globalvar2     checkbo3.checked = globalvar3 end sub
