Reading a text file into a TextBox

[Tomexx]

Hi,
I need to read-in contents of a text file (Readme file) into a text box on my Help.frm. What would be the right approach? Can anyone help?

Thanks.

Maybe this code helps you.

Dim oneLine As String 'one line of the file
'open the file
Open "c:\myfile.txt" For Input As #1
    'read each line and add it to the textbox
    Do
        'read a line
        Line Input #1,oneLine
        'add it to the textbox
        Text1.Text = Text1.Text & oneLine & VBCRLF
    Loop Until Eof(1)
'close the file
Close #1

Maybe you should cosider using a RichTextBox control. It does whatever a regular Textbox would do but even better. If your help text file is very long you should use a RichTextBox.

RichTextBox1.LoadFile "C:\MyTxtFile.txt", 1

The size limit of a textbox is 64 KB, so I don't think you need a richtextbox. But a richtextbox also supports formatting.

The RTF Box uses up a lot more resources than a standard Textbox.

Here is a faster way of loading the file. (using a standard TextBox)

Open "MyFile.txt" For Input As #1
Text1 = Input(LOF(1), 1)
Close #1

well, what is the limit in size for a rtb?

The limit for a RTF box is the virtual memory that Windows has assigned your program.
That is it doesn't have a limit other than the RAM.
