Hi,

I have two text files and I want to append TextFileB onto the end of TextFileA

TextFileA is 3 million rows
TextFileB is 100 rows

The problem is that TextFileA is 3 million rows long. So I do not want to
create an array, load all of TextFileA, then output TextFileA and then the
100 lines of TextFileB (that would take a long time). That is the only way I
know of to append B to the end of A.

Can anyone help?

Thanks!

How about something like this.
fNum=FreeFile
Open TextFileA For Append As fNum
Print fNum, TextFileB
Close fNum

Hi,

I tried the following code but go the error message "method not valid
without suitable object" on the line 'Print fNum, TextFileB'

Code:
Sub TestCode()

'How about something like this.
'fNum = FreeFile
'Open TextFileA For Append As fNum
'Print fNum, TextFileB
'Close fNum

TextFileA = "C:\IScenarioSets1.csv"
TextFileB = "C:\IScenarioSets2.csv"

fNum = FreeFile
Open TextFileA For Append As fNum
Print fNum, TextFileB
Close fNum

End Sub

Give this a go.
Sub TestCode()
Dim fNum As Integer, fNum2 As Integer
Dim yourInfo As String
TextFileA = "C:\IScenarioSets1.csv"
TextFileB = "C:\IScenarioSets2.csv"
fNum = FreeFile
Open TextFileA For Append As fNum
fNum2 = FreeFile
Open TextFileB For Input As fNum2
Do While Not EOF(fNum2)
Line Input #fNum2, yourInfo
Print #fNum, yourInfo
Loop
Close #fNum
Close #fNum2
End Sub

If your files are really **text** files as the names indicate, you can
always go "lo-tech"... start Windows command processor (Start
Button/(All)Programs/Accessories/CommandPrompt)... if your files are both in
the same directory, 'cd' to that directory, for example....

cd c:\directory1\directory2\etc.

Then execute this command (note the plus sign)...

copy TextFileA.txt+TextFileB.txt TextFileA.txt

If the files are located in different directories, then you can execute the
following command without using 'cd' first...

copy <Path\TextFileA.txt+<Path\TextFileB.txt <Path\TextFileA.txt

where you would substitute the complete path to each file where I have
indicated <Path. By the way, if you want to test this out before actually
changing TextFileA, change the last file to a non-existent filename and the
concatenated file will be written to it instead. For example, using the
first command where you used 'cd' to move to the common directory...

copy TextFileA.txt+TextFileB.txt TestFile.txt

Doing this will create a new file in the common directory and then place the
concatenated file into it. You can then see if the result is what you want
before making it permanent.

Thank you both for your help on this!

Here is one option:

___________________________________

Sub AppendTextFile()

Const ForReading = 1
Const ForAppending = 8

Dim StrTransfer As String

txtFileAname = "C:\IScenarioSet1.csv"
txtFileBname = "C:\IScenarioSet2.csv"

Set FSO = CreateObject("Scripting.FileSystemObject")

Set txtFileB = FSO.OpenTextFile(txtFileBname, ForReading)
StrTransfer = txtFileB.ReadAll
txtFileB.Close

Set txtFileA = FSO.OpenTextFile(txtFileAname, ForAppending)
txtFileA.Write vbCrLf & StrTransfer
txtFileA.Close

Set FSO = Nothing

End Sub
