[RESOLVED] Text file stuff

Hey everyone

Does anyone know how to open a file and add the "%" at the beginning and the end of a file.

Thanks

I would simply say to read the file and then write it back.
You can either read it all into a variable then write it back to the same file or open the file (open "MYFILE.txt" for input as #1) and another temp file (open "MyTempFile.txt" for output as #2) and then read from one and write to the other. Then delete the old one (Kill) and rename the new one to the old one.

1)

Code:

---

Open "MyFile.txt" for input as #1

Do
 Line input #1, ReadNewLine
 MyString = Mystring & ReadNewLine
loop until EOF(1)

close #1

---

You now have the whole file in MyString (string variable).
Just open the file again and write

Code:

---

Open "MyFile.txt" for output as #1
? #1, "%"
 ? #1, MyString
? #1, "%"
close #1

---

2)

Code:

---

Open "MyFile.txt" for input as #1
Open "MyTempFile.txt" for output as #2

? #2, "%"

Do
  Line Input #1, ReadNewLine
  ? #2, ReadNewLine
loop until EOF(1)

? #2, "%"

Close #1
Close #2

Kill "MyFile.txt"
Name "MyTempFile.txt" as "MyFile.txt"

---

I didn't include the paths, you would have to include paths or it will write to the same path as you project (I think)... Even if you want it to write to your project path it is still better to use App.Path & "\MyFile.txt"

Okay you need the code to look something like this...
Open "MyFile.txt" for output as #1
Print #1
Close #1

That works pretty good but when vb prints back to the file it's all on one line.
The input looks like this below.I need the file to be preserved like it was.

Thanks

If you are using Print #1, [VARIABLE] (same as ? #1) then it shouldn't be one line.
The Print # ends each line.
Make sure your using Line Input # to get it.

I pasted your txt sample into a MyFile.txt file.
Then ran this code....

Code:

---

Open "MyFile.txt" For Input As #1
Open "MyTempFile.txt" For Output As #2


Print #2, "%"

Do

  Line Input #1, ReadLine
  Print #2, ReadLine

Loop Until EOF(1)

Print #2, "%"

Close #1
Close #2

Kill "MyFile.txt"
Name "MyTempFile.txt" As "MyFile.txt"

---

The text file that resulted was,

%
