Need to retrieve the data from the function and write in the text file in macros excel

Question

I have three functions, in macros excel. i am showing an example to understand

Sub main()
    Dim Obj As Object
    Dim File As Object
    Set Obj = CreateObject("Scripting.FileSystemObject")
    Set File = Obj.createtextfile("c:\amix.txt"", True)
    A
    B
    C
End sub

Public Function A()
     file.writeline("ABC")
End Function



Public Function B()
     file.writeline("Def")
End Function



Public Function C()
     file.writeline("GHI")
End Function

Now i want to write all this function data into amix.txt notepad

And also if we write the two(Creating the Obj and Files) lines in every function, the text file is over riding for every function.

Now can you please suggest me with the code where i can get rid of my problem?

Answer 1

Obviously, the error is you are not passing File to your functions. Try the following. It's tried and tested to work. Also, your directory has an extra " at the end. Not sure if just a typo on your part.

Sub main()
    Dim Obj As Object
    Dim File As Object
    Set Obj = CreateObject("Scripting.FileSystemObject")
    Set File = Obj.CreateTextFile("c:\amix.txt", True)
    WriteA File
    WriteB File
    WriteC File
End Sub

Public Function WriteA(File As Object)
     File.writeline "ABC"
End Function

Public Function WriteB(File As Object)
     File.writeline "DEF"
End Function

Public Function WriteC(File As Object)
     File.writeline "GHI"
End Function

Hope this helps.

EDIT:

If you want to call a function inside another, just make sure the inner function exists first. There are no issues doing this. However, the practice is generally unorthodox at best. Same follows (tested and working):

Public Function WriteC(File As Object)
     'Calling WriteB inside WriteC as well.
     File.writeline "GHI"
     WriteB File
End Function

Let us know if this helps.

You need to make your text file object Global. You also should use Subs rather than Functions . For example:

    Dim Obj As Object
    Dim Ffile As Object
Sub main()
    Set Obj = CreateObject("Scripting.FileSystemObject")
    Set Ffile = Obj.createtextfile("C:\TestFolder\amix.txt", True)
    Call A
    Call B
    Call C
End Sub

Sub A()
     Ffile.writeline ("ABC")
End Sub

Sub B()
     Ffile.writeline ("Def")
End Sub

Sub C()
     Ffile.writeline ("GHI")
End Sub

Also, eventually you should perform

Ffile.Close
