I have a Text File which contains a Single Alpha Numeric Word on Each Line. I'd like to place the contents of the text file into an EDITBOX so that the user can make a selection. The Text File will occasionally be edited.

I can retrieve the Data by using one of the following options (although I am open to other suggestions).

Code:
* Option 1

CREATE CURSOR Logmenu ;
	( Log_Select varchar(15) )

LogSource = "Log_Selection.txt"	
Append From (LogSource) type sdf

* Option 2

LOCAL LogSelect AS String
	m.LogSelect = FILETOSTR("Log_Selection.txt")

However I don't seem to be able get my head around how to populate the EDITBOX with the Data.

Any help would be most appreciated.

Regards,

David.

It could be easy as this:

Code:
Thisform.MyEditbox.Value = FILETOSTR("Log_Selection.txt")

If the user edits the data and you need to write it back to your text file, just do the reverse:

Code:
STRTOFILE(Thisform.MyEditbox.Value, "Log_Selection.txt")

To pick one line, you should use a grid or a listbox, not an editbox. And then option 1, reading the file as sdf (or csv) into a dbf (cursor) is fine for that.

An editbox does allows selection oif any amount of text, muiltiple lines, but also partial lines, so if you want to know a specific item = line number picked the editbox is the wrong control for that.
Grids are a bit complicated, but for a single column grid this could be as simple as that:

Code:
CREATE CURSOR Logmenu ;
	( Log_Select varchar(15) )

LogSource = "Log_Selection.txt"	
Append From (LogSource) type sdf
Go Top

thisform.addobject("grid1","grid")
thisform.grid1.collumncount = 1
thisform.grid1.width = 250
thisform.grid1.recordsource = "Logmenu"
thisform.grid1.column1.controlsource = "Log_Select"
thisform.grid1.column1.width = 250
thisform.grid1.visible = .t.

Or add the grid at design time.

Bye, Olaf.

PS: I forgot to tell an important detail: The row a user picks will be the current record of the cursor, so the choice made is Logmenu.log_select. It'll perhaps start at the bottom row after the append, and the grid displays nothing or only that last row. So you better GO TOP IN Logmenu.

Olaf, I realised as soon as I had populated the EDITBOX that I probably wouldn't be able to achieve what I had set out to do.

I ran your code and also populated a LISTBOX on the same form for comparison. The LISTBOX meets my requirements, however, I will go with the GRID option as I think it will be more flexible as I continue to develop and improve the application.

Thank you very much for your help, much appreciated.
