Question

Foxpro 9.0 Memo field structure

Asked by: fmoore0001

I have a memo field imported from Access that has some RICH TEXT formalling characters I want to remove and save in the Foxpro filelds.

Character phrases like "\par " are easy.

cNotes = STRTRAN(cNotes, "\par ", "")

But phrases like this are harder:

I could assume that anything line with a "\c" could be removed, but how do I find the end of like.  Is there any embedded character for carriage returns?

You can try using the microsoft richtext control. It has Text and TextRTF properties.

 

by: CaptainCyrilPosted on 2009-03-10 at 23:10:49ID: 23854273

Use the richtext control by Microsoft has tusharkanvinde has point out. Or you can use Microsoft Word in Automation.

LOCAL oRTFText AS RichText.RichTextCtrl.1

or
you can append the document after you save it on the disk as:
CREATE CURSOR rtf (document G)
cFileName = "c:\path\rtftemp.rtf"
STRTOFILE(csvmemo,cFileName)
APPEND GENERAL document FROM (cFileName) CLASS "RICHTEXT.RICHTEXTCTRL.1"

 

by: tusharkanvindePosted on 2009-03-10 at 23:45:49ID: 23854405

Something like

loRTF= CreateObject("richtext.richtextctrl.1")
loRTF.textRTF = YourTable.YourMemoField
REPLACE YourMemoField WITH loRTF.Text IN YourTable

Tushars Code will work, if you have the original memo RTF texts. Otherwise you'll need to create something like a rtf parser that knows what is RTF tags and what is text.

I'm afraid if you don't have the full RTF texts you're out of luck. Maybe something like this will remove all rtf tags, but might remove more or less than you want. So please only test it on a copy of your data.

Still it's much better to let an RTF control extract the net text and remove rtf tags, it knows best, what is what.

Bye, Olaf.
