How to read and write combined data from/to the field

Hi all,I need to save the properties about 50 controls form in Access 2003 data base, such as length, width and height, distance from the top, distance from the left, font color, background color, etc . And since Access 2003 only has the ability to manage 255 fields for each table. It is not possible to save any of the features in one field. How can I save and read the properties of each control in a field together as separated, such as:

lbl(1): "120|300|250|500|True|330|False|, ..."
lbl(2): "90|140|50|310|Fale|100|False|, ..."

The user can click on any of the controls such as labels, images, etc. to change the size and location of each control.
My challenge is reading and writing data together and separately.

I would be grateful if you have a code in this field.

How do you have more than 255 properties for a single control??

I don't have 255 properties for one control. Each control has about 10 properties, and I have 50 controls, which makes 500 properties for all controls. If I want to put one field for each control in the table, it is not possible because each table in Access 2003 only manages 255 fields.

If possible, put all 10 features of each control in one field of the table together but separately. Only 50 fields are required.
The challenge is how to store and read these features from the database

Aha, the cross product of all controls with all properties.
I think a better approach is to have a row per control.
Create a table with columns for all the unique properties like name, x, y, width, height, backcolor, forecolor etc etc.
Then create a new entry (row) in the table for each control.

Urggghhh..... and now i'm going to spice this up by introducing "Parent" to the controls.
In a nutshell: Use JSON with Json-Objects, JSON-Fields, JSON-Arrays, JSON-ChildObjects etc. etc. blahblahblah and build a hierarchy, and save it as a single String or BLOB

In this example, for each control, I considered a column under the name of the control and a column to store its properties. Now the problem is how to read and save the properties of a control that are together?

lbl(1): "120|300|250|500|True|330|False|, ..."
lbl(2): "90|140|50|310|Fale|100|False|, ..."

I was able to read the arrays with split, but I could not save the arrays in the field.

Dim Data() As String
Dim moni As New ADODB.Recordset

If moni.state = adStateOpen Then
moni.Close moni.Open ("select * from Moni_Settings "), dB, adOpenKeyset, adLockOptimistic
Data = Split(Text1, "|") newData = Data(0) & "," & Data(1) & "," & Data(2) & "," & Data(3) & "," & Data(4) & "," & Data(5) & "," & Data(6) & "," & Data(7) 'etc.
lbl(0).height = Data(0)
lbl(0).width = Data(1)
lbl(0).Left = Data(2)
lbl(0).Top = Data(3)
lbl(0).ForeColor = Data(4)
lbl(0).FontName = Data(5)
lbl(0).FontSize = Data(6)
lbl(0).FontBold = Data(7)
End If

Thank you for your answer, do you have an example for this?

Read the JSON-Documents (gazillions on the net)
a JSON-Object can have Properties/Fields with simple Datatypes,
can have properties/fields being an array of values,
can have (Child-) Objects, which themselves can have….

what does this remind you of?
