You are going to disrespect a person for asking a general question?

Unfortunately, while we do our best to guide management and our users on the 
form layout, ultimately they have the final say on how they want their forms to 
look and run.
Some environments do not allow for programmers to provide input into the design 
process.  

But I can assure you that Lena is a top notch programmer with an extensive 
career in programming.  And should be greatly respected, regardless of what 
questions she might ask.

Just so you know, most every "edit" type control has a handle (it is a window 
unto itself).  You can see how this would become burdensome for an applications 
main window to know the whereabouts of the myriad child windows spawned in its 
instance.

I was just trying to remember when the last time I can recall an application 
that would have had 600 plus controls hosted in one form....  Oh yeah, never.  
Not to say it hasn't happened before, because I know it has been attempted, and 
when troubles like you have described are mentioned in other NGs, the person 
seeking guidance is usually not handled with the greatest respect...

You need to derail this idea at your earliest...

Tom/Javier  - thanks for your hints and thoughts.

This is a variable form (not data bound).  I do not believe I am at the 
systems memory limits.  I do not see major fluctuations in memory, the form 
does not retrieve tons of data.
The controls utilize various tables, although some of the controls do use 
the same table(s).
I create temporary views in the "On Before Start EEP" and do not explicitly 
drop the temp views upon exit.
Some of the tables do have same column names, but are by design; for they 
are foreign keys.
I am not using alias column names in my views.  Was never an apparent issue 
in the past, but I will have to rethink that subject.

I've been building and testing this form basically tab page by tab page. 
The views, tables, list views were put into place towards the start  my 
efforts.
The strangeness started after about 550 controls on form with: when in 
design mode, clicking on the control does not display that controls 
attributes (height, width, position ...) after running in design mode.  If I 
right click, I can get the display to work.
The control's attribute display does update if freshly opened via design 
mode (before running via design mode).

The error message "List index out of bounds" started after about the 648th 
control.  The error message appears when hitting the button that closes the 
form.
This button does some checking, issues CLOSEWINDOW which goes into the ON 
CLOSE EEP.  On close just sets some variables and closes form.
I've put in a trace, and the error message appears after the RETURN in ON 
Close is issued.  So tracing is showing me nothing.
Again this error does not appear if form is RUN out of design mode.

I removed 2 of the last controls I placed on the form, and the error message 
goes away.  If I add two variable RadioButtons, the error returns.  I 
removed the 2 radiobuttons the error goes away.  This is why I am thinking 
I've hit some number of controls on a form limit.........

Tom - I with you on the thoughts of breaking up the form into more than one 
form.  But my directive was to show/do everything on one form!

Any other ideas?

Also, if you are creating temporary tables on the "before design: and 
deleting them on the "on exit" EEP, the tables will no longer be there when 
you run the form from the designer, exit the form and return to the 
designer.

Two items:

1.       You hitting your system's memory limits?

2.       Do all the controls go to the same table or are they spread over 
multiple tables and views? Check for duplicate column names. (Same column 
names in a Table and a View) or (same column name in two different tables) = 
duplicates if used in the same form or report. It forced me to learn about 
using aliases in views.
Sounds like you have 40 items a page. I had similar issues with an Enhanced 
tab with lots of pages with dense info entry. All those lookups need to get 
loaded when you start up. Ended up breaking it up into a Form with a menu 
system using Bit and Speed buttons. Each menu button has its own specific 
Forms with about 40 items each and is isolated from the others. Load 40 
items compared to 650 at one time.  Lot less memory, better control over 
names, unneeded variables cleared at form exit, and easier to track what was 
going on. Runs quick.

Subject: [RBASE-L] - RBWin 7.6 - Controls on a form limit

Hi,
I am working with RBase Win 7.6 and I have been creating a form with an 
Enhanced tab control with 14 pages.
Within all those pages/tabs, I have about 650 controls.  Labels, var labels, 
bit buttons, var Lookup Combo boxes, var edit, var lookup ListViews etc...

I've been noticing lately as I've been adding on more controls,  while in 
design mode; things are not acting as usual.
Such as after I run form in design mode and exit the running of the form via 
a button, I get an error "List Index out of Bounds ###".  The ### changes 
from 648, 649 ... 659, 660.   If I take one control off the form (I think 
any kind of control, button, listview); I can stop the error from happening.
Running form not directly from design mode, I do not get the error message.

After running form via design mode:
When back in design mode, and I save the form, this "save" icon does not 
always gray out (save completed)
Also when I click on a control (again in design mode), it does not update 
the status lower bar that shows the controls attributes (variable, width, 
height...)

Have I reached a per form limit of some kind?  Total number of controls per 
form?  Total number of tabs/pages per tab control?
Or is there something else that is causing my form to act strangely in while 
in design mode???

Any tips - clues would be greatly appreciated!

Lena
