VFP-6 Populating a combobox from aListPaths 2

[webmonger]

I have an application that I developed last year and am upgrading.

I've moved to a pageframe control which works very well.

My problem is with a 'previous path' selection combo. this has worked for ages with the following code to populate in in the main form's init procedure

cTablename = "paths"
IF file(cTablename+".dbf")
	IF !USED(cTablename)
		USE (cTablename) in 0
	ENDIF
	SELECT (cTablename)
	GO top
*!*		COPY to temp
	IF reccount() >0
		SELECT myPath FROM paths INTO ARRAY aListPaths
		IF VARTYPE(aListPaths) = "U"
			DIMENSION aListPaths(1)
			aListPaths(1) = ""
		ENDIF
		

	ELSE

		DIMENSION aListPaths(1)
		aListPaths(1) = ""
	ENDIF
ENDIF

Now I only see one entry when I get to that page (page1).

I just don't know what combo property or code line could do that to me. Can anyone suggest anything to get me out of my misery?

Thanks

Bryan

HI

I would replace the whole of above code with following..
I assume you do not need the paths table to remain open for any other processing.

DIMENSION aListPaths(1)
IF file("paths.dbf")
   SELECT myPath FROM paths INTO ARRAY aListPaths
ENDIF

Thanks again Ramani

Was your code for a similar situation some years ago <G>

I have replace the code and still have the problem. Both versions do it.

I removed the combo and put a new one on the page1.

I ran Builder and nominated the aListPaths array.

No procedures were changed.

When I run exe I still see only one row.

I investigated with some listcount values and alen(aListPaths) to labels on the form.

I see the array as having 5 elements and the combo showing 1 both on init and when clicked.

Something else is restricting the rows showing in the combo.
But what could do that?

thanks

Bryan,

3 questions..

I assume that the original exe still shows 5 items in the combo?

In the new version, is the item in the combo the same as the first element in the array?

What are the values of the 5 elements in the array?

HI

Is the first character \ in the paths list ?

Combobox will ignore the rows having \ as the first character.

Probably use a dummy character or a drive letter as your first character for the combo. OR use a grid to imitate the combo box and replace the combo with the grid.

1 - Yes

2 - Yes

3 - Previously selected paths.

The idea is that a 3rd Party application stores projects ( Genealogy)in a user determined folder. Within that folder can be a number of projects.

So on Page 1 they select the folder to investigate.

And on page 2 they get a combo with the list of available projects ( foxpro database based)

This combo is based on an array also and works correctly. I will try and code a grid as ramani suggests until a cause is found.

My immediaie problem is solved. After writing a new code segment to add a particular path to the array all entries appear. So it's a mystery that will remain unsolved - until it happens again. somehow the array was out of scope.

Thanks
