Hi,

>>

LOCAL o, oNode
o= thisform.oletree
oNode=o.Nodes.Add(,1,"1_", "Compraventa",0)
oNode.Image="manos"
o.Nodes.Add(,1,"2_", "Utilidades",0)
o.Nodes.Add(,1,"3_", "Ayuda",0)
o.Nodes.Add("1_", 4, "4_", "Contratos",0)

image "manos" is on imalistcontrol on same form, but this oNode.image="manos" shows an error.

Are you confusing the imagelist with the required image. Try:

ThisForm.oleTree.ImageList = ThisForm.Manos
oNode.Image = "imagelistkey"

HTH,
