Updating Window Caption Without Focus

I'm using FindWindow, FindWindowEx and SetWindowText to set the caption of Window1 as I click in Window2. It works fine, except the caption does not change until I set the focus back Window1.

What API can I use to get Window1 to refresh/redraw without putting the focus back on it?

Code:

---

Private Const WM_PAINT = &HF


Private Declare Function SendMessage Lib "user32"  _ Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As _
Long, ByVal wParam As Long, lParam As Any) As Long

SendMessage(hWnd, WM_PAINT,0&,0&,0&)

Thanks Jim.

I did find another way though, I hhave the window object (As VBIDE.Window) which has a SetFocus method. At first, I didn't want to use that because I thought it would shift the focus to the wrong window, but it doesn't. It just repaints it. Weird.

Jim,

I found my method to be a little too flickery, so I tried yours. It doesn't work, I think because WM_PAINT only updates the client area of the window.

I had to use WM_NCPAINT (with wparam = 1) to update the caption.

Cheers,
