EnumChildWindows and EM_GETSELTEXT

[kinryuu@gmail.com]

I'm trying to write a program that captures selected text from the
active window. I have everything setup as far as getting the foreground
window (with GetForegroundWi ndow()) and I'm using EnumChildWindow s to
iterate through the child windows until I get something useful.

The problem is that every single child window of the foreground window
returns a single space as the selected text, even if I know that a
control on that window has highlighted text.

Is EM_GETSELTEXT not the right message? I've also tried WM_GETTEXT and
that simply returns an empty string for each child window.

Here's the pertinent code:

public static bool Enum(int hwndChild, int lParam)
{
StringBuilder builder = new StringBuilder() ;
SendMessage(hwn dChild, Win32.User.EM_G ETSELTEXT, 50, builder);
if (builder.Length != 0)
{
buffer = builder.ToStrin g();
return false;
}
else
{
return true;
}
}
