Excel VBA - Multiple Issues for a newbie.
 

Hi all,
This is my first VBA Projet and whilst it works (in it's current stat
/ content), I've stumbled across some problems.
So if you are willing to amble through my ramblings and assist, I'll b
greatfully apreciative of any suggestion / solutions you are willing t
offer.

The Named Array's: 'Doctors' / 'Doctors Array' / 'Doctors Table' al
have data in them currently. And when using the 'RemoveButton' wil
successfully remove all records. But when I attempt to add a recor
fails due to the 'Doctors' Named Array being a #REF error due to th
last record being removed (so I'd concluded).

I attempted to add a dummy record and retried to add a record, but i
again fell over as (-and I'm assuming here again-) due to not enoug
records for the script to work.

My questions a a
- Do I need to re-write what I've completed thus far ?
- Need to build a user function to handle this problem?
- Have I overlooked some basic fundamentals in the design of th
script?
- Is my existing code well structured??
- Areas of improvement ??
- Need to see a shrink?aAgain any help is apreciated.
-If anyone would like a copy of the XLS to view, let me know.-

Cheers,

Excel VBA - Multiple Issues for a newbie.
 

Cameron,
What you've got so far looks good ( a couple of issues
with the construction of your If statements, particularly
in the textbox changes).

Have a look at the CurrentRegion and Rows properties.

If you add a line to check the number of rows in your
named range, then you can perhaps avoid the issues you
have highlighted.

A full analysis of your code is not really possible here,
but if you send me the workbook (hold the size under 400k
), I'll go over it and send it back with comments. My
email is without the
nospam.

Your code seems to be worthwhile as it stands, don't throw
it out (there is a school of thought that code should
never be discarded if it works, any code can be recycled,
and recycling is a good thing).

You have retained the Excel default naming of the
controls on your userform. While it may be simple enough
in this application, you chould seriously consider using
descriptive names for controls, e.g. txtDoctorName.
This will let you know the type of control, and the data
it should contain. Similarly the prefixes cbo, lst, cmd
or btn, chk and opt are commonly used for combobox,
listbox, command button, check box and option box
controls.

A nested If Then statement doesn't need its own Else.
If logical_test1 Then
If Logical_Test2 then
If logical_test3 Then
Do_something
Else
Do_something_different
End if
End if
end if

Note the use of indenting to simplify reading code.

Also, I note you have used And in one line of your if
statements, is there a reason why you didn't concatenate
multiple Ands?

If Logical_test1 AND Logical_test2 AND Logical_test3 Then
Do_something
Else
Do_something_else
End If

Hope this is of use to you

Steve
