help with table design for Code Library


J

Jan T

Hi. I am using MS Access 2010 and want to build a database for
organizing my Code snippets and functions. I'd like to have different
categories and subcategories in a form where I can build a tree-view
kontroll on the very left side of the form. Then, when clicking in the
tree, I want the relevant function names og procedure names appear in
a table on the right side. Clicking that sub- or functionname, will
make a new modular form, with the actual code, Show.

My question is how do I build the tables.

I started with two tables, one called tblCode with the following
fields:
ID
HeaderID
CodeName
CodeText
AuthorName

and another table I named tblHeadings;
HeadingID
Heading

How should I design the tables so that I can have a functioning tree
with headings like:

Excel
|____ Worksheet
|____ Cell
|____ Fonts
|____ Functions
Outlook
|____ Mail
|____ Task
|____ Contact
|____ Exporting/Importing
|____ Appoiment

Any help is very much appriciated. Thanx in advance!

Regards
Jan T.

Hi Jan

You would need a minimum 3 tier table approach.

Change the TierNames to suit your need

Table.1
txtTier1Id 'example = 1
txtAppName 'example = Excel

Table.2
txtTier1Id 'example = 1
txtTier2ID 'example = 1
txtTier2Name 'example = Worksheet

Table.3
txtTier2ID 'example = 1
txtTier3ID 'example = 1
txtTier3Name 'example = Cell

.......................................................

Table.1
txtTier1Id 'example = 1
txtAppName 'example = Excel

Table.2
txtTier1Id 'example = 1
txtTier2ID 'example = 2
txtTier2Name 'example = Worksheet

Table.3
txtTier2ID 'example = 2
txtTier3ID 'example = 2
txtTier3Name 'example = Fonts

.......................................................

Table.1
txtTier1Id 'example = 1
txtAppName 'example = Excel

Table.2
txtTier1Id 'example = 1
txtTier2ID 'example = 2
txtTier2Name 'example = Worksheet

Table.3
txtTier2ID 'example = 2
txtTier3ID 'example = 3
txtTier3Name 'example = Functions

...........................................................

Each tier will filter off the previous tier, Etc..... Depending on how
many tiers you want to go.

each of your tiers should only need to be a text field, with the
exception of the actual code field as you would most likely need to use
a memo field due to the 255 char restriction in text fields.

Base your Parent form on Table.1, then each of the sub forms on each
tiers table.2, table.3 etc.....

I can't help you with a fancy tree view but this should get you started
in the right direction.

Hm, I found that a little static and may be I don't get it.
This treeview must be dynamic, that is, it must be no
problem to have only one or more than tree levels.

But thank you anyway for taking the time.

May be if I find a solution I would like to share it in this group.
So I search on the net and found excactly what I was looking for.

I will bulid my table like the table Employees in the Nortwind.mdb
where Employees have a field RefersTo. I then will implement
this idéa in my own project.

For more information se the following article:
http://support.microsoft.com/kb/209891/

So, to make a form, I placed the Microsoft Treeview Contol 6 to
the left of the form, and then a multiline text box to the right of
the
Userform. When clicking one of the nodes in the tree, the
corresponding code is displayed in the text box to the right.

The table design is therefor going to be like this I guess:

tblCode
ID
HeaderID
CodeName
CodeText
AuthorName

And it is all in one single table. Hope this work. Have not
tested it yet.

BTW what does HTH stands for? (I always wondered?)
