Text files and Inner Workings

ok here is my problem. I have a program which produces a list of dimensions needed to build a subwoofer enclosure. What I have planned to do is pre-make some text files with HTML coding to show an image at the top in the center, but then have my program take the text in a text box and load it into the file underneath the image. I don't need it to write the HTML code for the text as I can just put it in the file. But thats the problem. i don't know how to take whats in my text box and add it into the file without overwriting what's already in the file. Then I want to save that text file with an *.html extension. Any ideas? I would love to hear some. Thank you.

There is no easy way you still have to write the HTML Code no matter what you do.

Open the main file for read
Open a second file for Write
As you read each line search for the position you want to place the new text and write each line to the new file.
When you've found it - write the new text to the new file.
Then continue reading and writing the Original file to the new file.
Delete the old file and rename the new file as the old file.

Good luck

I would put text in the text file that will represent the places where you want to insert text. Use something that would not normally occur in a text file, such as %$Field1$%. Then just use the replace function to replace it with the textbox text.

Isn't the replace function in the VB IDE.
You still have to read the old file and write to a new file to include any text.
HTML can also include text from a file onto the screen just change the text file to change the text - no messing with the HTML file.

The Replace function is a function of VB. It is used for replacing a character or characters in a string with another character or string. I am not referring to the replace operation of the IDE.

Code:

Dim String1 as String
Dim String2 As String
String1 = "This is a test"
String2 = "is not"
String1 = Replace(String1, "is", String2)

After running this code, String1 would be "This is not a test"
