Drew,
No, but you don't fundamentally change a product if it's working.
Jim.

But you couldn't run Access 97 in Windows 3.1, right? Reminds me of the
volkswagon bug distributor design.

Drew,
Well remember that Access started out under Win 3.x, which had fixed
and
limited resource stacks. Microsoft said at the time that the intent was
to
limit the number of windows, especially with continuous forms to get
around
that limitation.
Jim.

The original reason given for this was to conserve resources when
running.

I was working on a newer version of the 'minicalendar' form I had built
years ago. The new one has a lot of bells and whistles, and one of the
features I wanted to put into it was to be able to set it as a subform.
The problem I ran into (other then lack of time to work on it), is that
one of the 'new' features was that the form was shaped. Had some
'animation' with it too (sliding menus for different functions). That
is when I discovered how goofy Access forms are. Windows, in Windows,
are very simple creatures. On a typical window, each control is another
window, usually of a specific class. There are API calls to deal with
special windows, and APIs to deal with generic windows. For example, if
you want to read the text of a textbox on a window, you just find it's
API, and the text is the 'window text' property, where as the same
property for a normal window would be it's caption. You can also
programmatically run through the contents of a listbox or combobox this
way. (I used that one time in an application where I had to take the
contents of a listbox with thousands of entries, and put them in a text
file. The Listbox was running in a window of a out of the box
application, and I had no programming interface to read it, but thanks
to how windows work, I was able to use standard window API's to
programmatically read the contents of the listbox).
Anywho, back to Access forms. In an Access form, the controls on the
form aren't actually windows, instead, everything is actually an 'image'
and only the current control is a separate window...which is really
crazy, because as you move focus from control to control, Access is
literally changing that window and turning the previous control to an
image. Go figure.
So since that new MiniCalendar was trying to modify itself as a window,
and it no longer had true window properties, it wouldn't work as a
subform.
Ok, did I just type all this out cause I'm bored today?

Subject: [AccessD] Lebans' Calendar Screen
Hello to Everyone!
Last week I learned how to use Stephen Lebans' date selection calendar.
This is not an ActiveX control, but uses API calls. If you haven't
looked
at this calendar you should. It's quite versatile and is
user-configurable.
For my customers' use I often record short tutorial videos. If you'd
like
to view the video I made for this Calendar, you can go to
http://www.promationsystems.com/demo.htm. The link is at the bottom of
the
page. The video is in WMV format, is about 11 minutes long, and goes
through all the features.
I also may have 'stumbled' across a way of using this on a subform.
Instead
of instantiating the class (clsMonthCal) in the form as per the
instructions
on Lebans' site, I instantiated this in a standard module (thanks to
Lambert
and Charlotte!). I'm posting the code to do this below:
'--------------------------------------
'-- In a form or subform (I have only tried a 1st level subform)
Private Sub butGetDates_Click()
'-- The End Date is optional but is needed if you want a date range.
'-- Pass the complete reference to the date controls so that _
the standard module can write back to them.
Call OpenCalendar(Forms("frmMain")("txtStartDate"), Me.hWnd,
Forms("frmMain")("txtEndDate"))
End Sub
'--------------------------------------
'-- In a standard module
'-- Get the example .mdb from Lebans' site. _
It contains the class module (clsMonthCal) and 4 standard modules. _
Instructions are on the page for this Calendar.
Private mc As clsMonthCal
Public Sub OpenCalendar(txtStartDateOnForm As TextBox, lnghwnd As Long,
Optional txtEndDateOnForm As TextBox)
Dim blnRet As Boolean
Dim dteStart As Date
Dim dteEnd As Date
'-- Create an instance of our Class
Set mc = New clsMonthCal
'-- Set the hWndForm Property
mc.hWndForm = lnghwnd
'-- Date fields are typically empty to start with
dteStart = Nz(txtStartDateOnForm, 0)
dteEnd = 0
'-- Run the calendar. The calendar is modal during this line
blnRet = ShowMonthCalendar(mc, dteStart, dteEnd)
If blnRet = True Then
txtStartDateOnForm = dteStart
If Not txtEndDateOnForm Is Nothing Then
txtEndDateOnForm = dteEnd
End If
Else
'-- Add any message here if you want to _
inform the user that no date was selected
End If
End Sub
'-----------------------------
Perhaps someone will find this to be helpful!
Dan
