output with text files

i have this complicated (at least i think so :P) project for programming class: Create a program that loads and breaks up a text file into different fields.

Private Sub Command1_Click()

Do While Not EOF(1) And Left$(Line1, 10) <> "Card Name:"
Line Input #1, Line1
Text1 = Line1

Loop
End Sub

that'll return the full line of text beginning with "card name:" but thats all i got for now, i need each line in a different text box so im getting stuck now, any help would be great!

VB Code:

Do While Not EOF(1) And Left$(Line1, 10) <> "Card Name:"

That line of code is NOT good! You do not want to keep reading the file if you reach eof. Your code requires both conditions to be true. What if eof is true but left$(Line1,10)<>"Card Name:" is not true? Then your program would try to keep reading the file even though it was already at the eof - crash! Never put another condition with eof. Eof should be the only test performed when reading a file to the end.

As for your question.

If you put a text box on a form and then copy and paste the same text box on the same form, vb will ask if you want to create a control array. (click on Yes!) A control array is just like an array, but with control.

So the first text box you put on the form would be text1(0) and the next one would be text1(1) and so on . . .

Assuming you had 20 text boxes and 20 lines in your imput file . . .

VB Code:

Private Sub Command1_Click()
    Dim strLineOfText As String
    Dim i As Integer
    
    i = 0
    Do While Not EOF(1)
        Line Input #1, strLineOfText
        Text1(i) = strLineOfText
        i = i + 1
    Loop
End Sub

I really don't want to do your homework because that wouldn't help you in the long run, but I hope that helps. If that example doesn't make sense, just let me know.

i was thinking of using an array, my teacher told me i shouldn't have to but i guess my initial idea was right... thanks i'll try to work with what you've told me

You and your teacher are both right. An array would be easier (you are correct) but you also don't need to (she is correct).

Good luck with the project and let us know if you run into any snags.

If your text file is delimited by commas or tabs you could look up
the Split command and put it into an array and put each element
into their respective text boxes.

hi,

why to take more text boxes.take one text box and display like this

Dim strLineOfText As String
Dim i As Integer

Do While Not EOF(1)
Line Input #1, strLineOfText
text1.text=text1.text & vbcrlf
Loop

armbruster: i tried the code and when i got an error i remembered trying something almost the same but gave up on the idea because of this error:

Complie Error:
Can't Assign to Read Only Property

because of this line:

Text1(i) = strLineOfText

Ya know, it's always the easy stuff I screw up - the hard stuff is no problem !

should be . . .

VB Code:

Text1(i)[COLOR=red].Text[/COLOR]  = strLineOfText

yikes, i wish i wasn't so bad at VB... but another error came up:

Compile Error:

Wrong number of arguments or invalid property assignment


:eek:

post your code or zip your project . . .

what line is highlighted when you get the error?

i included other attempts but leave them commented out in my program

ERROR
Compile Error:

Wrong number of arguments or invalid property assignment
/ERROR :)

Dim strLineOfText As String
Dim i As Integer
Dim Line1 As String
Option Explicit



Private Sub Command1_Click()

i = 0
Do While Not EOF(1)
Line Input #1, strLineOfText
Text1(i).Text = strLineOfText
i = i + 1
Loop


'Do While Not EOF(1)
' Line Input #1, strLineOfText
' Text1(i).Text = strLineOfText
' i = i + 1
'Loop

'Do While Not EOF(1) And Left$(Line1, 10) <> "Card Name:"
' Line Input #1, Line1
' Text1 = Line1
'Loop
End Sub

Private Sub Form_Load()
i = 0
Open "H:\Visual Basic\Magic Database\od_spoiler_en.txt" For Input As #1
End Sub

Don't open your file until you need to and close it when you are done!

VB Code:

Option Explicit
 
Dim strLineOfText As String
Dim i As Integer
Dim strFile As String
 
Private Sub Command1_Click()
    i = 0
    strFile = "H:\Visual Basic\Magic Database\od_spoiler_en.txt"
    Open strFile For Input As #1
        Do While Not EOF(1)
            Line Input #1, strLineOfText
            Text1(i).Text = strLineOfText
            i = i + 1
        Loop
    Close #1
End Sub

I suspected that you did not have a control array on your form so I created one text box and got the same error you got.

Make sure you have several text boxes on your form with the same name!

You need to have a textbox control array for this to work!
