extracting the text out of a binary file

[RSH]

Hi,

I have quite a few .DAT data files that i need to extract the data out of.
When i open the files in a text editor I see all of the text that I need to
get at BUT there are a lot of junk (binary?) characters and white space in
non logical formatting positions.

Here is a small sample of what the data looks like:

0~ 0501101010512505011132451235 > 
ô ô

X 3> Bô

Is it possible to filter out all the junk characters and just get at the
text? If so could you provide a sample of how?

I tried doing a string replace but the number of characters in the array
were getting way out of control. I was wondering if the binaryreader class
might be what I'm looking for but I have no idea on what that really does.

Thanks!

You can filter the string to just accept range of the numbers and letters.

But why do you read binary files using text file methods?

Primariy i just need to get at the data...which is all there but
unfortunately there are thousands of useless characters with the text. i
tried Regex to strip the useless characters but everything disappears when i
try that which leads me to believe it is an encoding mismatch. If you look
at my example of the text file below you will see what is happening. The
files are from an old Microfocus ISAM database which no simple database
viewer exists. many products are out there but they are several thousand
dollars, which is way out of range for us.

I mean using *range*, for example imagine you've stored whole data in a
string file named strOld and you want to exclude ascii charachter instead of
numbers
and letters:

Dim newStr As String
Dim i As Integer
For i = 0 To oldStr.Length - 1
If oldStr.Chars(i) >= Chr(48) AndAlso oldStr.Chars(i) <= Chr(172) Then
newStr += oldStr.Chars(i)
End If
Next

You can play with if-statement to get your desired result.

Oh thats good...that worked BUT...is there anyway to keep single instances
of spaces...in other words if there are two or more spaces next to each
other they can be eliminated...and i would like to keep the linefeeds too.

Thanks alot!

I found a tricky way about your "spacing" problem,
but maybe there are also better ways:

For i = 0 To oldStr.Length - 1
If oldStr.Chars(i) >= Chr(32) AndAlso oldStr.Chars(i) <= Chr(172) Then
If Not (oldStr.Substring(i).StartsWith(Chr(32)) AndAlso _
oldStr.Chars(i + 1) = Chr(32)) Then newStr += oldStr.Chars(i)
End If
Next
About LFs, I'm not sure what to do, please send me a sample
of your files (if they are less than 1 MB!) and the code you use to read
those files.

a better loop is:
For i = 0 To oldStr.Length - 2
If oldStr.Chars(i) >= Chr(32) AndAlso oldStr.Chars(i) <= Chr(172) Then
If Not (oldStr.Substring(i, 2) = " ") Then newStr += oldStr.Chars(i) '*
End If
Next

* There are 2 space characters in double qutations ( ...(i,2)=" ")
