Subject: Text File

 

Question:

Is there a way to read data or strings from a .txt file and if so how?

Thank you

 

The most common way to read a text file, is the Open method. To read from a file, will use the Input keyword:

Open FileName for Input as #1

For example:

Open “C:\MyText.txt”

Than, to read a line, use the Line Input method:

Line Input #FileNumber, StringVarable

For example:

Line Input #1, FirstLine

You can use the EOF (End Of File) function to determine when you are on the last line:

EOF(FileNumber)

For example: If EOF(1) then MsgBox (“Compleate”)

The last method that you need to know is the Close method:

Close #FileNumber This method clothes the file.

 

This is a simple code for a program that prints a file:

 

Private Sub Form_Load()

Form1.Show 'loads the form.

Open "C:\mytext.txt"

For Input As #1

Dim LastLine As String

Dim AllText As String

Do Until EOF(1)

Line Input #1, LastLine

AllText = AllText & LastLine & vbNewLine

Loop

Print AllText

End Sub
