vb.net - How Do I Change ForeColor of all Labels in a Form? -

i writing down simple schedule planner app using winforms in visual basic .net, , have "edit preferences" want user able change colors of labels. tried use code:

public sub darkmode(byval darkmodeon boolean)     if darkmodeon         each c control in me.controls             if c isnot lbltitle                 if typeof c label directcast(c, label).forecolor = color.fromargb(255, 255, 255)             elseif typeof c panel                 each pnlpanel panel in me.controls.oftype(of panel)()                     pnlpanel.backcolor = color.fromargb(66, 66, 66)                 next             end if         next end sub 

but when run code, changes forecolor of labels immediate children of form , changes not apply labels inside other containers panels. there way change forecolor of labels, not immediate children of form?

probably changing if elseif helps out.

for each c control in me.controls         if typeof c panel             each pnlpanel panel in me.controls.oftype(of panel)()                 pnlpanel.backcolor = color.fromargb(66, 66, 66)             next         elseif c isnot lbltitle             if typeof c label directcast(c, label).forecolor = color.fromargb(255, 255, 255)         end if     next
