read and write variables from textfile

[Per Juul Larsen]

Hi.
My Textfile looks like this

Variable 1
Variable 2
Variable 3
Variable 4

On opening the application it will read the textfile, and assign each
line of variable to at textfield in VB and then close the file.
How can I do this

Re: read and write variables from textfile

There's a trick to it... just in case you're a student
trying to get us to do his homework for him, I'll not
give you actual code... but I'll tell you the secret....

Read it in the same way you wrote it, same variable
types and all. open, read1,read2,rea d3,read4,close.

Now assuming you're not a cheating student, you
should now have all the information you need.

If you're NOT a cheating student, e-mail me a
copy of your ID, to prove it, and I'll send you some
actual code. :)

Thank You for a kind answer. No I am not a student. I am retired long
ago.(65) Just try to keep up what I have lost long ago. I used to open
file for input to a textbox or array etc... but wondering if there is an
easier way to do it.
thanks

Re: read and write variables from textfile

You may want to consider using a data structure.
There's a tiny bit more setup, but it will allow you
to read/write all your variables in one shot, as
opposed to multiple reads/writes.

As an example, I had written an appliance parts
database a long time ago, in regular BASIC, in
which I DIMmed my variables, as such....

DIM A As String * 32
DIM B As String * 32
(originally longer list)

then did a PRINT# x, A : print# x, A to write
and/or a LINEINPUT #x, A : LINEINPUT #x, B
to read it back.

When I found my original source code, and started
converting it to VB6, I changed to a structure, so I
started with setting up a record variable...

Public Type Record
PartNumber As String * 32
PartDescription As String * 32
End Type

and ...
Dim r As Record

Then, I was able to open the database file at the start
of the program via an Open App.Path + "\db.pdb" For Random As #dBase Len =
Len(r)
which would allow me to SEEK directly to a specified
record number, and do a PUT #x, ,r or GET #x, r to
read or write the data, which was then accessed
as r.PartNumber or r.PartDescripti on

Am I going too fast for you? If you'd like a copy of the final code
to disassemble, and learn from, send me an e-mail, and I'll
reply with a .zip of it in an attachment.

I may be missing something but would this work?


Open "yourfile.t xt" for input as #3

input #1, text1.text
input #2, text2.text
input #3, text3.text
input #3, text4.text

close #3

Thank You

I saw the light...

I read line by line until it comes to end of the file like this
Dim a, b, c, d
Open "C:\users\publi c\temp\ok.txt" For Input As #1

While Not EOF(1)
Line Input #1, a
Text1.Text = a
Line Input #1, b
Text2.Text = b
Line Input #1, c
Text3.Text = c
Line Input #1, d
Text4.Text = d

Wend
Close #1

hi

Sometimes the answer is right in front of you and you can not see it!!!!.
Thank you for your reply ... I have solved the task by reading the text
file and then line by line store the line to variables and then insert
them in the application.
my email is juul@larsen.dk

kind regards pjl
