   Like i said i tried to create a button instead of the rebar control and it worked.

[HSE]

Rebar is in place, just empty.

Is posible that you don't see nothing until to insert a band?

[xandaz]

maybe

[jj2007]

invoke  CreateWindowEx,0, addr WC_TOOLBARWINDOW32

It wouldn't hurt if you did some error checking.

[xandaz]

   yeah....there was king no error. The band  had to be inserted. sorry for making you think

[hutch--]

Something basic, at a WM_CREATE you can only use the handle supplied in the WndProc, once the CreateWindowEx() has returned you can use its handle as the parent for other controls.
