Tab chars in memo fields on form (1 Viewer)

[madmike]

I have an Access 2010 system that stores program source code. (PostScript, but that is not relevant to this problem) in a table as a memo field. It works fine except that forms showing the source code donn't deal with tab chars by indenting, as one would expect. <CR> and <LF> are fine. But not tab char.

The table contains the tab chars OK (and I can, for example) generate HTML by replacing each tab char by 3 &nbsp; html chars.

But I would like to be able to edit the source code on a form, using a control that deals with the tab char properly, including showing them, indenting, allowing insertion/deletion, ... I can obviously do all that with (for example) Notepad ++. But I need to be able to do it with code in the tables.

Is this possible? And if so, how?

Thanks for any help, Mike

have you tried setting your memo field to rich text?

Yes. If I do that, even the <CR><LF> characters get ignored.

I will prototype the following approach:

1. When a record becomes the current record, convert all <tab> chars to 3 spaces and set 'dirty' to false
2. Allow spaces to be inserted; if any change is made to the field, set dirty to true
3. When the record needs to be saved/closed, check dirty; if it is true, convert spaces back to <tab> characters (after dividing the number of contiguous blanks by 3 of course)

Clumsy. But I think it should work. Obviously, the depth of indexing can be changed by swapping 3 to 4 (for example) in a global database variable.

Does anyone have a simpler solution?

Rich text uses html code and you can't mix the two

see post#3 in this link for determining the required html code

how to find richtext codes for highlight, underline etc

You might use this with the objective of highlighting searched for text in a text field, or perhaps to format the date and time values in a single field a different colour (although date/time fields would then be text format). Will also work with numbers but they also will be converted to text...

other thing to try is using vbTab
