It should work if you call GetWindowLong(GWL_STYLE) for the hWndEdit window, set/remove the ES_CENTER/ES_LEFT/ES_RIGHT styles and call SetWindowLong(GWL_STYLE) to apply the changes.

For a normal Edit control the alignment styles may be set and removed after window creation. The combo box uses a normal edit control, so it should work. But it might be that the combo box prevents such changes to the edit control. If this is the case, you are out of luck.

Ha! I tried it myself. All you need is to force a redraw of the control after you changed the styles.

Hi

What you mean with "force redraw"?
SendMessage and WM_PAINT?

Calling Refresh should be enough.

Assuming that you defined the constants and API functions correctly, it is correct, yes.

When I tried it myself on Tuesday, all I needed was to move another window over the control so that it will redraw. I thought that Refresh would be sufficient. Obviously it is not sufficient. Try this:

Code: Select all

Call SetWindowPos(ComboBox1.hWndEdit, 0, 0, 0, 0, 0, SWP_NOSIZE Or SWP_NOMOVE Or SWP_NOOWNERZORDER Or SWP_NOZORDER)
If this does not help, try this:

Code: Select all

Call SetWindowPos(ComboBox1.hWndEdit, 0, 0, 0, 0, 0, SWP_NOSIZE Or SWP_NOMOVE Or SWP_NOOWNERZORDER Or SWP_NOZORDER Or SWP_FRAMECHANGED)
If this also does not help, you could toggle the Visible property twice, but then the control will flicker.

Does your application have Windows skins enabled? I tried on Windows 7 x64 with skins enabled. Maybe it works only if skinning is enabled (Windows loads a newer version of comctl32.dll then).
