I'm making a gui for an archaic fortran program. The fortran program can run automatically when a text file with all the inputs are in the same folder. I have almost no experience with visual basic, but I have gotten a text field to write to a file. What I need is help with a loop and formatting the output since the fortran program needs the input formatted perfectly. this is the input form i have http://img60.imageshack.us/img60/10... ------------- Public Class TSMOD Private Sub Label1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Label1.Click End Sub Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim FILE_NAME As String = "h:\test.txt" Dim i As Integer Dim arytext(100) As String For i = 1 To 69 arytext(i) = TextBox1.Text Next If System.IO.File.Exists(FILE_NAME) = True Then Dim objWriter As New System.IO.StreamWriter(FILE_NAME) For i = 1 To 2 objWriter.WriteLine(i & " " & arytext(i)) Next objWriter.Close() MsgBox("Text written to file") Else MsgBox("File Does Not Exist") End If End Sub End Class ------------ My two questions are. How can I get the text box here to increment with the loop? arytext(i) = TextBox1.Text Then the hard part. Getting the output to be strictly formatted like this list i have (1st set of numbers right align in 3rd column, numbers will only be max of 2 places) (2nd set of number period at 19th column, 4 places after period no limit in front (until you hit the other number of course)) 1 2.9410 2 0.1250 3 0.0300 4 0.0300 22 6546.0348 Thanks for any help guys I have a correctly formatted copy of the list and code here, http://rafb.net/p/JDf6Kc29.html this link will last for 24 hours. is there a way to get things formatted in posts here? cause it's kinda hard to explain the formatting i need in my list without having it pasted right. thanks

How can I get the text box here to increment with the loop? I think I know what you're asking. Try moving i and aryText() to the class level, then add buttons to increment and decrement as needed. Optionally, you could look at some other controls (especially the ones for DB interaction). I don't have VS in front of me at the moment, so I can't name specifics. Then the hard part. Getting the output to be strictly formatted like this list i have That should be relatively easy. Read up on String.Format is there a way to get things formatted in posts here? Nope. Can't do it. Impossible. Use the HTML PRE tags.

thanks for the link i'll read up on that. don't think you got what i was talking about. For i = 1 To 69 arytext(i) = TextBox1.Text Next in that I want to increment the TextBox1.Text to TextBox2.Text and so on. so arytext(69) would be equal to TextBox69.Text thanks for the pre tags of course you can't edit the first post but watever. the list 1 2.9410 2 0.1250 3 0.0300 4 0.0300 69 646846.6483

That's much harder. Hard enough that I'd suggest rethinking your GUI. What I would do would be to make an array of TextBoxes, then programmically place them. Then you'd have no problem iterating though them. If order doesn't matter, you could iterate though Me.Controls looking for TextBoxes, then incrementing i when you find one.

so I just need arytext(1) = TextBox1.Text ............. ........................ .............................. ...................................... ................................................. ............................................................... .......................................................................................... arytext(69) = TextBox69.Text then?

Again, alternative approaches would be better, but if you're determined to use separate TextBoxes, then yes, I suppose. But don't become rooted in an implementation just because you already have something that kinda does what you want. VB.NET offers so much more. Also, make sure your StreamWriter is writing to ASCII, and not UNICODE. If you don't, expect FORTRAN to either crash or spew out bad data.

well thanks for the hints and tips, I'll see what I can do. Then probably I'll be back. EDIT Read through that and didn't understand anything really. Now I know why I'm an engineer and not a programmer. I have the logical skills but suck at the syntax and commands.
