Open file to write and read at the same time
 

http://support.microsoft.com/support...eio/fileio.asp
File Access with Visual Basic® for Applications

Pretty vague just to say it doesn't work and put up 17 lines of code.
Pehaps the above will give you some ideas.

Hi all,

I'm trying to read the first line of a text file and write some lines
to the same file if the file exists. Have tried the codes below but
doesnt work!

Start of code...

=============================================
hFile = FreeFile 'Get the next free file handle
nFile = FreeFile
attachmentpath = "C:\test.txt"

If Len(Dir(attachmentpath)) = 0 Then
Open attachmentpath For Output Access Write Shared As _
hFile
Print #hFile, "test msg" , strInput
Else
Open attachmentpath For Input Access Read Shared As _
nFile Line Input #nFile, strline
Close #nFile

Open attachmentpath For Output Access Write Lock Read _
Write As hFile
Print #hFile, "test msg" , strInput
End If

Close hFile
Close nFile
==============================================
End of code...

Thanks in advance

Open file to write and read at the same time
 

Hi again,

My intention is to read the 1st line from the text file using the
following code:

OPEN ATTACHMENTPATH FOR INPUT ACCESS READ SHARED AS _
NFILE LINE INPUT #NFILE, STRLINE
CLOSE #NFILE
'...(1) [/b]

AND WRITE TO THE SAME FILE USING THESE CODES:

[b]OPEN ATTACHMENTPATH FOR OUTPUT ACCESS WRITE LOCK READ _
WRITE AS HFILE
PRINT #HFILE, \"TEST MSG\" , STRINPUT
'...(2)

However, the message from (2) is not written to the text file even
though I have closed the file (1) and re-opened it for writing (2).

Thanks again!!!

Notice how you use

#Nfile
in the first command

and just Hfile in the second.

shouldn't it be

#Hfile.
