Hi Ganne;

  You can use the ShellExecute API from within your Web App but remember that the App (although stored in PowerServer) gets loaded and executed on the client PC's web browser. The client machine will not have access to the remote server unless you have some kind of UNC drive mapping going on. Which is another access possibility. BTW: Since PB 2017 is Unicode, you should be using the ShellExecuteW API and not the old ANSI one.

  Besides Marco's suggestion on using the PowerServer's FileServer mechanism to access remote files, you can also use a PB based Web Service (WS). The IIS based WS can then access the server's resources - in this case the file you are after - and then transfer the file contents back to the WS caller. In your case, that would be your Web App ( WS client). A variation on this would be to have the WS load the file contents into a TEMP Table blob column and let the Web App pull the contents from there using a SelectBlob command.

Food for thought.

Hi Ganne,

you cannot.

The function will be executed on the client machine, not on the server, because it is called from the generated Javascript code.

If you want to access files on the server side, one workaround is to use the AppeonFileService object from appeon_workarounds.pbl. 

Alternative approaches may involve the deployment of .NET Web Services from PB.

Cheers,

Marco
