Razzak,
I made a mix of your suggestions and those from Larry.
And it works fine in my var lookup listview.
However, if I delete any text in the bLOB field, it isn't recognized as
empty and the color doesn't change to the 'empty' state.
How can I test in code if a BLOB is really empty ?
Thanks,
Luc Delcoigne

Luc,
In that case ...
Did you know that you can customize individual row background and
font color using the DB Grid Row Background Color Field and Row
Font Color Field options of DB Grid Properties to achieve your goal?
Here's how:
A quick tutorial to help you understand the basic concept.
01. Add two columns to the corresponding table with BLOB data.
RowBackgroundColor TEXT 20
RowFontColor TEXT 20
02. Create a form based on corresponding table with BLOB data.
While in Form Designer, place "Enhanced DB Grid Control"
Right-Click or [F11] for Enhanced DB Grid Properties
Effects:
Assign RowBackgroundColor column for Row Background Color Field.
Assign RowFontColor column for Row Font Color Field.
03. Adjust all other properties as necessary.
04. Save the form and then close the form designer.
05. Create a quick command file as follows:
-- Example 01
UPDATE tablename SET +
RowBackgroundColor = 'WHITE', RowFontColor = 'RED' +
WHERE ColumnNameWithBlobdata IS NULL
UPDATE tablename SET +
RowBackgroundColor = 'WHITE', RowFontColor = 'GREEN' +
WHERE ColumnNameWithBlobdata IS NOT NULL
CLS
BROWSE USING formname ...
-- Example 02
UPDATE tablename SET +
RowBackgroundColor = 'SILVER', RowFontColor = 'BLACK' +
WHERE ColumnNameWithBlobdata IS NULL
UPDATE tablename SET +
RowBackgroundColor = 'WHITE', RowFontColor = 'BLACK' +
WHERE ColumnNameWithBlobdata IS NOT NULL
CLS
BROWSE USING formname ...
-- Example 03
UPDATE tablename SET +
RowBackgroundColor = '[R124,G83,B23]', RowFontColor = 'WHITE' +
WHERE ColumnNameWithBlobdata IS NULL
UPDATE tablename SET +
RowBackgroundColor = '[R169,G176,B209]', RowFontColor = 'BLACK' +
WHERE ColumnNameWithBlobdata IS NOT NULL
CLS
BROWSE USING formname ...
06. Make sure to have fun!
Very Best R:egards,
Razzak.
