You must know if your checbox is in a resource (dialog box) or in a window.
In a dialog box you can get the handle as this:
   invoke GetDlgItem,Hparente,NumIdentifiant
or use this syntax
      invoke SendDlgItemMessage,Hparente,NumIdentifiant,
            BM_GETCHECK,0, 0

then use "CheckDlgButton"

[ragdog]

I use not a checkbox button i use checkbox in a treeview

Working with normal checkboxbutton in a Dialog if not this probelm

[ToutEnMasm]

Perhaps could you put here your piece of code ?.

I coming not further i need help from member with experince for programming a threeview

Now have solved to get all Rootname of the treeview and nodes name

My probelm is i try to write all RootNames and Nodes Names to a file
root1
  -nodes1
  -nodes2
  -nodes3
  ...
  ..
  .
root2
  -nodes1
  -nodes2
  -nodes3
  ...
  ..

Written File:

Root1=nodes1,nodes2,nodes3....
Root2=nodes1,nodes2,nodes3....

This write file procedur have i not this problem only with get all rootnames and nodes names from the TreeView

This get all root names
