How can I prevent the user from changing the widths of ListView columns?

Suppose you are using a Win32 ListView control in report mode, and you’ve got all your columns set up perfectly, and you don’t want the user to resize them. How do you do that?

There is no ListView style for preventing column resize, but there is a header control style to prevent sizing: HDS_NOSIZING. This style requires Common Controls version 6, but I’m sure you’re all using that version already, right?

auto hdr = ListView_GetHeader(hwndLV);
SetWindowLong(hdr, GWL_STYLE,
              GetWindowLong(hdr, GWL_STYLE) | HDS_NOSIZING);

Whether the columns can be resized is independent of whether the columns can be rearranged, which you specify by setting the LVS_EX_HEADER­DRAG­DROP ListView extended style.

ListView_SetExtendedListViewStyleEx(hwndLV,
                                    LVS_EX_HEADERDRAGDROP,
                                    LVS_EX_HEADERDRAGDROP);

Okay, but what if you’re stuck in the dark ages with version 5 of the Common Controls? We’ll look at that next time.

    Two reasons you might still be on Common Controls version 5:

    1) You are developing a GUI application that runs on Server Core. Trust me, this is sensible. The GUI application is an oversized dialog box for configuring the service. (There is automation. Unless you are managing more than one it's a lot easier to open the GUI application than use the automation.) Common Controls 5 works better than 6 on Server Core. (We had to write a bit of code because checkboxes misrender (probably due to a missing font), but it's far less than the alternative.)

    2) You've hit one of...

    Do you still get the old version 5.82 of common controls if your application doesn’t have any manifest? Even on modern Windows? Meaning the header control doesn’t understand the style?
