Hi,
Does anyone know how Windows allocates memory for controls? For example,
given a huge Panel, say, in a relatively much smaller Form with scrollbars,
will Windows attempt to allocate a huge area of memory for the Panel's
visible surface, or will it only allocate as much as is required (i.e. as
much as is visible)?
If the former, is there any way of preventing this? Like telling it that at
this point in time, only X amount of the...

Is there anything I can do about the apparent limit on the number of
textboxes that have calculations as their control source on a form or
report in ms-access? I have a query that pulls together all the fields
from two tables, each with about 20 fields. I then have a statistics
form that has the query as its source and the form has 273 textboxes
on, each with a calculation based on the underlying query values. The

There are a maximum number of controls can be put in a form for VB3 to VB6.
The BOL of VBNET do not say VBNET also has this limitation.
Because the clients want add more functions from time to time.
I find one of the form reach the maximum number of controls.
If I add one more control in this form, the program will get error at
InitializeComponent.
Are anyone find similar situation

Ok.. I have a form with lots of stuff on it; a tool strip panel, menu strip,
data binding elements (dataset, binding source, table adapter), tab control
with 7 tab pages, each page contains a picture box, lots of text boxes (for
input).. you get the idea. All of a sudden everything on the form has
disappeared, it looks like a blank, newly created form. I can still get to
the properties of every item on the form using the drop-down box in...

I have a Back End database (split) that is on a smokin' hot machine
(dual processor, 2 gig RAM, XP Pro SP2) and I'm getting an error that
says the database (back end file) is "opened exclusively" by someone
else.
I looked at the number of sessions and noticed that when the number of
sessions were at 10, any new user launching the front end would get
the "exclusive" error message.
There is no security in place and no login required.

Is there a "best practice" maximum number of controls that can be
loaded on to a tab control before things start getting messy and
sluggish? I'm asking for a "best practice" maximum number across all
tabs and not the maximum number that is theoretically possible.
I figure that trying to add lots of controls to lots of tabs must
affect performance at some point.
Any help is appreciated.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
