Wide characters in a printer name causes crash

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hello,

I'm developing a browser plugin that prints PDFs silently in the background.  Everything is working great, except for one minor issue: whenever the printer name contains anything other than ASCII, my plugin crashes completely when issuing a DPLPrintDocument command.  And I'm just using the normal DPLGetDefaultPrinterName(InstanceID) as the printer's name.  (I've also tried fetching the default printer myself into a string and passing that, with the same result.

I think this is unlikely to come up in the real world, but it does seem like a problem.  Has anybody else seen this?

	Hi Xan! It works like designed i fear. Which version you're using? If you look into the reference you can see that the activex-version returns with a string, delphi- and dll-version with a widestring. I think you should try the dll-version (widestring result)?
