Copyfile Binair with Java Script

Classic Servoy
1

Hello Everyone,

Does anybody know how to copy a file binary in Java script??
in Dos the syntax is:
copy /b sourcefile destination

Youll probably wonder why I want to do this well Im making a database which also contains pathnames of .tiff files (drawings) and because a tif file is a printable format you can copy it binair direct into a printerqueue without any driver or userinterferance. It is a very fast and simple procedure the output is the original (tiff) size when possible or else fit to papersize.
When you just copy the file into a printerqueue you`ll get a lot of pages containing ascii rubish.

ps. for some newer printers/multifunctionals it is also possible to copy pdf files into the printerqueue.

Using or omitting the /B switch when copying to a device

When destination is a device (for example, COM1 or LPT1), the /B switch
causes MS-DOS to copy data to the device in binary mode. In binary mode, all
characters (including such special characters as CTRL+C, CTRL+S, CTRL+Z, and
carriage return) are copied to the device as data. Whereas, omission of the
/B switch causes MS-DOS to copy data to the device in ASCII mode. In ASCII
mode, such special characters as those previously listed may cause MS-DOS to
take special action during the copying process.

Hope that anyone can help me.

Thanks in advance Rene

You can use executeProgram to execute system operating commands.

Hello Jan,

So this should work

Field:
VT_FilePath contains the value ‘O:\TDD\47828_Ooshop\300-399\old_docs\047828-330-40011-EN-B.TIF’

Method:
if ( utils.stringMiddle(application.getOSName(), 1, 7) == “Windows”)
{
if (plugins.file.convertStringToJSFile(VT_FilePath.filepath).exists())
{
var VT_Queue = ‘\\nlprnserv01\nljerom-c’
application.executeProgramInBackground(‘Cmd.exe’,'copy /b ’ + VT_FilePath + ’ ’ + VT_Queue)
}
}

It doesn’t return an error but it doesn’t work either

Can you please tell me what I`m doing wrong

Is there by the way another way to copy files binary than with the cmd.exe perhaps its possible with Java or a plugin.
Another challenge for the Servoy Team

Thanks in advance Rene

try to read the result back into a variable so you check in that variable the possible mistake:

var returnedMessage = application.ExecuteProgam…etc

NOTE that if you execute in the background you obviously can’t get the errorcode(s) back unless you write them out to a file.

You can also try to use the file-plugin’s copy function to copy files to your queue. I don’t know if that will work though. If I recall well the file-plugin is available in the latest 2.0 Release candidate.

var VT_Queue = ‘\\nlprnserv01\nljerom-c’
application.executeProgramInBackground(‘Cmd.exe’,'copy /b ’ + VT_FilePath + ’ ’ + VT_Queue)

application.executeProgram(‘Cmd.exe’,‘copy’,‘/b’,‘filepath’);

The file plugin as shipped with the Servoy 2.0 (beta)version has copyFile function.
