Does the new hWnd handle need to be released after the form is closed?

this code works fine for me to add cut paste functionality to edit control
but this code also starts controlling sip-keyboard, which is undesired for me ,Is there any way by which I can add cut-paste functionality but control for sip-keyboard remains with me.

Hello,

thank you for the code. But I would like to comment that this code only adds the copy/cut/… context menu to the controls that are added directly in the form not any textBox added to a Panel or other containers.

So you have to do the same call with all the panel that have controls:

IntPtr hWnd = CreateWindowEx(0, WC_SIPPREF, “”, WS_CHILD,0, 0, 0, 0, panel1.Handle, IntPtr.Zero, IntPtr.Zero, IntPtr.Zero);

IntPtr hWnd = CreateWindowEx(0, WC_SIPPREF, “”, WS_CHILD,0, 0, 0, 0, panel2.Handle, IntPtr.Zero, IntPtr.Zero, IntPtr.Zero);

…

and so on.

By the way, congratulations by the blog.

It basically works from .NET CF via P/Invoke. But I discover a few things

(1) If a panel is used and the textbox is inside that Panel, the handle of the panel (and not the form) needs to passed to hWndParent in the call to CreateWindowEx. If the form handle is to be passed, no context menu will appear

(2) Context menu won’t appear on textboxes which are added to the form programmatically after the call to CreateWindowEx. Attempting to call CreateWindowEx again on the same form handle will hang the application!

(3) If an InputPanel is used to resize the form when the SIP appears, the context menu will disappear after a while. I am not sure exactly what triggers this, but I suspect it stops working either when the SIP is raised, or when the form is resized.

(4) Like Alex Prozor said, this will not work on a password textbox. When I tried this, my textbox is repainted properly but no context menu appears.

Any idea how to fix this? Thanks

Hi, unfortunately it doesn’t works on TextBoxes with non empty PasswordChar. (at least on WM6).
Textbox doesn’t repaint.
Do you have ideas how to fix it?
