I haven't tried this but the SWP_NOMOVE sounds like it would do what you want.

How to Create a Topmost or Floating Window in Visual Basic

Article ID: Q84251
Creation Date: 06-MAY-1992
Revision Date: 08-AUG-1996

The information in this article applies to:

- Standard and Professional Editions of Microsoft Visual Basic for
  Windows, versions 2.0 and 3.0

- Microsoft Visual Basic programming system for Windows, version 1.0

SUMMARY

You can create a "floating" window such as that used for the Microsoft Windows version 3.1 Clock by using the SetWindowPos Windows API call.

MORE INFORMATION

A floating (or Topmost) window is a window that remains constantly above all other windows, even when it is not active. Examples of floating windows are the Find dialog box in WRITE.EXE, and CLOCK.EXE (when Always on Top is selected from the Control menu).

For more information on this topic, please see the following article in the Microsoft Knowledge Base:

ARTICLE-ID: Q81137

TITLE     : INF: How to Create a Topmost Window

NOTE: Visual Basic forms that are TopMost Windows when they are in either Normal or Maximized positions will lose the Topmost setting when the Visual Basic program is Minimized. Visual Basic destroys the old window and creates a new one with the Icon in the Window. Therefore, in order for TopMost to stay in effect, the user needs to reset TopMost in the Resize event.

There are two methods to produce windows that "hover" or "float," one of which is possible in Visual Basic for Windows. This method is described below:

Use the following declarations:

Declare Function SetWindowPos Lib "User" (ByVal hWnd As Integer, ByVal hWndInsertAfter As Integer, ByVal X As Integer, ByVal Y As Integer, ByVal cx As Integer, ByVal cy As Integer, ByVal wFlags As Integer) As Integer ' The above Declare statement must appear on one line.

Global Const SWP_NOMOVE = 2 Global Const SWP_NOSIZE = 1 Global Const FLAGS = SWP_NOMOVE Or SWP_NOSIZE Global Const HWND_TOPMOST = -1 Global Const HWND_NOTOPMOST = -2 'Put global constants in bas module.

To set the form XXXX to TOPMOST, use the following code:

success% = SetWindowPos (XXXX.hWnd, HWND_TOPMOST, 0, 0, 0, 0, FLAGS) REM success% <> 0 When Successful

To reset the form XXXX to NON-TOPMOST, use the following code:

success% = SetWindowPos (XXXX.hWnd, HWND_NOTOPMOST, 0, 0, 0, 0, FLAGS) REM success% <> 0 When Successful

NOTE: This attribute was introduced in Windows, version 3.1, so remember to make a GetVersion() API call to determine whether the application is running under Windows, version 3.1.

This does not work.  All it does is to stop the window moving when you are changing the window properties using the setWindowPos API call.
