extension not shown when dialog is openend maximized

[bramboucherie]

if you open the openFileDialog, not maximized, the extension is added to the right. Then maximize it by double clicking the title bar. Everything resizes ok.

Then press cancel.

Then open the dialog again, it will automatically open again maximized. But now the extension will not be added.

I know nothing about windows messages, but:

I see that in maximized case the WM_SHOWWINDOW in WholeDialogWrapper WndProc does not arrive. Therefore Initcontrol is not called.

I'added:

                case Msg.WM_PAINT:
                    if (!mInitializated)
                        InitControls();
                    break;

now it works

I see the same problem.
How to fix it properly?

Ahhhh just struck this in the older version I have. Been using this code for over a week and it works with the multi-select "hack" to fix one of the other problems. Will have to look at this as well.

I have custom file types I'm making previews for and this works nicely.
