passing a textbox control in parameter list
Hi, I have an application that has about 3 subroutines that I'd like to use in another application so I decided to move them out into a DLL. Anyway, I moved them out and I call them from the two applications and they all work fine. When I moved them out, I temporarily commented out anything to do with the user interface - basically the routines do some processing of files that sometimes takes a long time so in the original application, the routines would update a little status form
What I'd like to do is popup the status form in each of the two applications and then call the subroutines in the DLL and then have the subroutine update the form. So I decided to add a simple textbox control in the subroutines' parameter list. When I go to compile the DLL I get
Compile error
Private object modules cannot be used in public object modules as parameters or return types for public procedures, as public data members, or as fields of public user defined type
This is the test subroutine that gives me the compile error
Public Sub test(t As Control
t.Text = "foobar
End Su
Am I stuck, am I doing something wrong? Is there a way around it? Any other suggestion of how to do what I'd like? Thanks

Tooltip causes an ASSERT() in a child dialog box
Hello experts,
I already posted about my problem a couple of days ago, but it's not
solved yet and I have some more details about it.
Using MS VC 6.0 and Vista.
I create a CTabCtrl control in a dialog box. For each tab, a child
dialog box contains a bunch of controls (CEdit, CComboBox...). I can
display tooltips for each control, no problem.
The problem is that when the cursor (I mean the mouse) leaves a
control, if it enters the tooltip area, I get an ASSERT() warning:
In WinCore.cpp
void CWnd::AssertValid() const
{
...
// should be a normal window
ASSERT(::IsWindow(m_hWnd));
...
}
This occurs only when the dialog boxes displayed in the tabs are CHILD
dialog boxes. If I choose "Overlapped" or "Popup", it works (but I
need a child dialog box).
What should I do to avoid this problem?
TXS
Phil
