Loop not moving to the next record

I'm so confused and frustrated!  I'm trying to loop through >5K records in table "Files" that list file locations, go to that file, get what I need, put it in another table "Alerts" and move to the next file name in the "Files" table.  It's parsing the data correctly and adding it to "Alerts" ok, but it's all from the same file!  It isn't moving to the next record in the "Files" table and it errors "too many files" after 255 loops.  I assume that's a Free File limitation but I don't know how else to handle it. The files have unique numbers at the end of their names, but I haven't had any luck using them either.  (example: C:\Documents and Settings\sellis\Desktop\Remedy KM\WallboardAlerts\Wallboard2.html")  Here's the code.  I'd really appreciate any suggestions.

Private Sub btnLoad_Click()

Dim txt As String
Dim strF As String
Dim dbs As Database
Dim rstA As Recordset
Dim rstF As Recordset
Set dbs = CurrentDb
Set rstA = dbs.OpenRecordset("Alerts")
Set rstF = dbs.OpenRecordset("Files", dbOpenDynaset)

'LOOP THROUGH FILES
With rstF

    Do While Not .EOF
        rstF.MoveNext
        Forms!form1.cmbFile = File
        Forms!form1.cmbFile.Requery
        Forms!form1.Refresh
       
'LOOP THROUGH HTML
        filenum = FreeFile
        Open Forms!form1.cmbFile For Input As #filenum
   
NextLine:
            Do While Not EOF(filenum)
            Line Input #filenum, txt
            If InStr(txt, "Alert Number:") > 0 Then
                    Do While InStr(txt, "<") > 0
                        txt = Replace(txt, Mid(txt, InStr(txt, "<"), InStr(txt, ">") - InStr(txt, "<") + 1), "")
                    Loop
                    txt = Right(txt, Len(txt) - InStr(txt, ":") - 1)
                    stralertno = Replace(txt, "&#45", "-")
            ElseIf InStr(txt, "Product affected:") > 0 Then
                    Do While InStr(txt, "<") > 0
                        txt = Replace(txt, Mid(txt, InStr(txt, "<"), InStr(txt, ">") - InStr(txt, "<") + 1), "")
                    Loop
                    txt = Right(txt, Len(txt) - InStr(txt, ":") - 1)
                    strprod = Replace(txt, "&#45", "-")
            End If
            Loop
NextFile:
            Close #FileName
    'ADD TO ALERTS TABLE
        With rstA
            .AddNew
            !AlertNo = stralertno
            !Prod = strprod
            .Update
        End With
    Loop
End With

End Sub

You are at no point reading any data from Files (rstF).

And as an 'incidentally' comment, if you were to read from Files you would be starting from the second record and missing out the first one.

You need a structure of :

rs.movefirst
Do until rs.eof
' do someprocessing

rs.movenext
Loop

Close #FileName
should probably be
Close #filenum
that would fix the "too many files" i guess

Right - I WAS trying to get them out of the recordset.  Then I changed it so that it was supposed to scroll through the records in a combo box on a form.  I've had more experience with controls than recordsets.  It was a shot in the dark.  Nevertheless....

Oh, Surone1 - Good job!  That eliminated that error.  I got 5400 of the same record.  1 down, 1 to go!

Hi,

little hint: If you go to the "Tools" - "Options" menu and select "Require Variable Declaration" (which automatically adds an "Option Explicit" line to all new modules) then you would have found the problem on your own. You should always declare any variable first and if you want to add this check to existing modules, add the line "Option Explicit" as first line in any module where it is missing.
If you use "Debug" - "Compile" the compiler will show you any such errors and any missing variable. With this method you will have a cleaner code as you are forced to think about any variable first.

Cheers,

Christian

by moving the .movenext down we prevent skipping the first record (file)

I'm afraid that I didn't find peter57r helpful.  He made two posts.  One that was just a statement "You are at no point reading any data from Files (rstF).", which was NOT AT ALL helpful.  The other was about reading the first record, which was not related to the problem I was having.  As he said, it was "incidentally."  I actually had .MoveFirst in the code originally and would have put it back once I got it working right.   Unfortunately, I found his tone to be a little bit sarcastic and condescending, so I didn't pay him much attention because of that.

As I looked more closely, at the posts, they were both solved by Surone1.  One issue was the "Close #FileName" vs "#FileNum" and the other was "forms!form1.cmbFile = .File" vs "=File"

These solved the problem I was having.  Capricorn1 was nice to re-post the code with the suggestions.  After re-examining the posts, the other helpful suggestion was from bitsqueezer, suggesting I use Option Explicit, which I did and was helpful.  But, I still think Surone1 should receive all the points.  

I do appreciate everyone's time in helping me with this.  I comment to everyone I know how wonderful the Experts are on this site.  You guys have saved me so many times.  Thank you.

Hi,

in my case it was only meant as I wrote: a little hint, not to assign points for as it was no solution for your problem...:-)
I'm glad that it helpful for you.
