[RESOLVED] Saving a file on a scanner (VB2005)

I have a Symbol MC9090 barcode scanner. I have figured out how to get the scanner part working. It now displays the data in the proper text boxes on the screen.

Now, when the user pushes a command button, I need to write data to a file and store it on the scanner. The file will be downloaded to a pc at the end of the user's shift.

Anybody have any sample code or can direct me to where I might find some?

Hi,
search the forum for 'streamwriter', or check it in the help file. There is sample code showing how to write to a text file

Thanks for your input. However, I was hoping for something a bit more specific to the barcode scanner. For instance, It does not like me using "My.Application..." that really throws any samples I can find out the window.

Hi,
sorry - is writing to the file not what you wanted, i.e.

Code:

---

Dim sw As StreamWriter
        sw = File.CreateText(DataPath & "myfile.txt")
        sw.WriteLine(textbox1.Text)
        sw.Flush()
        sw.Close()

---

I don't understand where 'My.Application' comes into it?

Right away it tells me that StreamWriter is not defined....

Hi,

Code:

---

imports system.io

---

or do

Code:

---

system.io.streamwriter

---

I figured that one out. Now I have a new issue. This is my code, at the moment:

'-- Process data
Dim csvfile As String = "%CSIDL_PROGRAM_FILES%\Technigraph"
Dim outFile As StreamWriter
outFile = File.CreateText(csvfile & "\Test.csv")

'-- Build the output file
outfile.writeline("XXX", Format(Now, "mm/dd/yyyy"), Format(Now, "hh:mm"), "T", TextBox1.Text, TextBox2.Text, TextBox3.Text)
outFile.flush()
outFile.close()

It appears to be having trouble creating the file. It says it can't find "\%CSIDL_PROGRAM_FILES%\Technigraph\Test.csv"

I don't understand why it is putting the "\" in the front of it. I copied the '%CSIDL_PROGRAM_FILES%\" from a sample application. the "\Technigrph" is the folder that the application resides in.

And the first time it is accessed, it won't be there.... you should check to see if the .folderExists first, if not, create it...THEN write to your file.

-tg

I thought this line created it...

outFile = File.CreateText(csvfile & "\Test.csv")

Hi,
%CSIDL_PROGRAM_FILES% is not valid - where did you get that from?

\Program Files\Technigraph would be your valid path

Pete

That did it. It only got the first "field", but I can work that out tomorrow. Thanks for the help.
