How do I get forground and background colour of a text object inside of a code-Jock SysListView32

Question

I need to test the foreground and background colour of text in a ListView table. The listView will be displaying alarms so each cell in this table may have a different foreground and background colour depending on the alarm.

The listView is a code-jock object so I have to use text recognition to find the text, which I have already done. Once the text is found I see no properties or styles to help me get the colour. How do I determine the foreground and background colours for text in each cell of this table?

My tests are written in VBScript.

All ideas are welcome.

Thanks.

Thanks Colin and HKosova,&nbsp;After posting I wrote this VB script to return the background colour as the most popular colour shown in an object.&nbsp;I wanted to find the foreground colour by returning the 2nd most popular colour but due to anti-aliasing it is possible that none of the pixels match the foreground colour, even though it may not look that way to our eye. To resolve this I changed Windows to turn ClearType off and then I was presented with just two colours (foreground and background).&nbsp;Hope this helps anyone else with the same issue.&nbsp;function getColours(myObj)&nbsp; 'Identify the colours used in myObj. The most popular will be the background colour and the second most popular will be the foreground colour.&nbsp; 'NOTE: Turn off ClearType text in your windows settings otherwise anti-aliasing could mean that none of the colours are the true foreground colour&nbsp; 'Returns an array (Background Colour, Foreground Colour)&nbsp; dim myPic&nbsp; dim maxWidth, maxHeight&nbsp; dim x,y,i, arrBounds&nbsp; dim max1, max2 'Index of highest count and second highest count in colour popularity&nbsp; redim colourStats(1,0) 'Colour, Count&nbsp; colourStats(0,0) = 0&nbsp; colourStats(1,0) = 0&nbsp;&nbsp;&nbsp;&nbsp; set myPic = myObj.picture&nbsp; maxWidth = myPic.size.width - 1&nbsp; maxHeight = myPic.size.height - 1&nbsp; for x = 1 to maxWidth&nbsp;&nbsp;&nbsp; for y = 1 to maxHeight&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; pixColour = myPic.pixels(x,y)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 'Try to match this pixel to one already in the colourStats array&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; found = false&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; arrBounds = ubound(colourStats,2)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; for i = 0 to arrBounds&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; if colourStats(0,i) = pixColour then 'If we have met this colour before&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; found = true&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; colourStats(1,i) = colourStats(1,i) + 1 'Increment the count for this colour&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; exit for&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; end if&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; next&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; if not found then 'Add the newly found colour to the colourStats array&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; redim preserve colourStats(1, arrBounds + 1)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; colourStats(0, arrBounds + 1) = pixColour&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; colourStats(1, arrBounds + 1) = 1&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; end if&nbsp;&nbsp;&nbsp; next&nbsp; next&nbsp; 'Search through the colourStats and return the most popular colours&nbsp;&nbsp; arrBounds = ubound(colourStats,2)&nbsp; max1 = 0&nbsp; max2 = 0&nbsp; for i = 0 to arrBounds&nbsp;&nbsp;&nbsp; if colourStats(1,i) &gt;= colourStats(1,max1) then&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; max2 = max1&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; max1 = i&nbsp;&nbsp;&nbsp; end if&nbsp;&nbsp;&nbsp; if colourStats(1,i) &lt; colourStats(1,max1) and colourStats(1,i) &gt;= colourStats(1,max2) then&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; max2 = i&nbsp;&nbsp;&nbsp; end if&nbsp;&nbsp;&nbsp;&nbsp; next&nbsp; getColours = array(colourStats(0,max1), colourStats(0,max2)) 'Return an array showing background and foreground colour valuesend functionsub test3&nbsp; set myObj =&nbsp;&lt;your object&gt;&nbsp; log.Picture myObj&nbsp; objColours = getColours(myObj)&nbsp; log.Checkpoint("Background colour is (" &amp; paddedhex(objColours(0),6) &amp; ").")&nbsp; log.Checkpoint("Foreground colour is (" &amp; paddedhex(objColours(1),6) &amp; ").")&nbsp;end sub&nbsp;function paddedHex(intValue, charCount)&nbsp;paddedHex = Right("00000000" &amp; hex(intValue), charCount)end function&nbsp;&nbsp;&nbsp;

Aaaargh!&nbsp;Someone posted a routine they'd written a while back. The routine effctively tested the colour of any given pixel on the screen and returned either RGB or HEX values for it.&nbsp;So, assuming you have screen co-ordinates for the area you want to check, you would be able to use this.&nbsp;BUT ......&nbsp;I've just had a search and I can't find the post! Sorry!&nbsp;I'm hoping by posting this, it will jog someone elses memory who does know the routine I'm talking about and they can point you towards it.&nbsp;Fingers crossed .....
