Append text in vb.net

Is the carriage return in the original file?


If so the only way that I can see to get rid of it is to re-write the whole thing.

What contains in a text file is this

Resultfile
accountnumber : 12345
/*

I want to remove  "/*" from my file, close a file and append new data from db to the same text file.

Right now it look like this

Resultfile
accountnumber : 12345

accountnumber : 67890
/*

instead of
Resultfile
accountnumber : 12345
accountnumber : 67890
/*

This is my code.

dim value as string = file.readalltext(myfile)
value = value.replace("/*", "")
dim sw as new streamwriter(myfile)
sw.writeline(value)
sw.close
dim test as streamwriter = file.appendtext(myfile)
test.writeline("mydata")
test.close

you also need to remove the new line.

Try this:
value.Remove(value.LastIndexOf(vbNewLine))

I would say that the code is far from perfect. Can you explain why do you
- open your file,
- replace ("/*", "")
- close file
 - open file immediately after that
-appebd text
-close file
?
Very expensive exercise in I/O

I'd do:
- open your file,
- replace ("/*", "mydata")
-close file

Code (didn't test)

dim value as string = file.readalltext(myfile)
' value = value.replace("/*", "") ' this line creates a blank line!!!
 value = value.replace("/*", "mydata") 
dim sw as new streamwriter(myfile)
sw.write(value)
sw.close
