enumprinters not returning network printers in win-7?

russferrer — Thu, 11 Oct 2012 19:05:57 +0000

I've been using the enumprinters progress code example to get a list of available printers since windows NT... and I have some clients (and myself) running windows 7 without a problem, but I have a client who is now switching to win-7, and the enumprinters fails to include networked printers in the list of available printers.
Any ideas, what I am missing?

here's a portion of the code I am using...

SET-SIZE(pPrinterEnum) = 30.

RUN EnumPrinters{&A} IN THIS-PROCEDURE (6,"",2,
GET-POINTER-VALUE(pPrinterEnum),

Library QuickPDF

pavels — Sat, 04 Feb 2012 07:52:52 +0000

Hi,

I am upset with trying to use functions from this library in OE 10.2A (as external). QuickPDF is for making PDF documents.

Have you anybody experience with it?

The another way how to use it is through user's own dll library making in .NET (C#, C++) but I have no chance with success to call own defined functions in my library.

My tries end with message 'Could not find the entrypoint (3260)'

So please could you give me a help hand with a sample how to use own created library in OE?

((using 'user32.dll' and many other same kind is not problem))

How to get the printer port number using windows API call

ashwathnp — Tue, 22 Mar 2011 09:48:31 +0000

Hi all,

Using the Windows API call, could you please tell us how to get the port number of the printer. Because while setting the value of activeprinter method/property of MS word 2007 it requires "printer name" on "port number".
The port number which we are trying to get by this method is equivalent to 'Session:printer-port"

Thanks,
Ashwath

Treeview - Checkbox issue

dwhite — Mon, 05 Apr 2010 14:32:16 +0000

Hi,
I am using a Treeview control (version 6.0) and it doesn't appear
to have the ability to disable checkboxes or grey them out from what I
can tell (if I'm wrong, could someone tell me how?)

Since it doesn't, I'm at least trying to write code in the node click
event that will prevent the user from changing the value of the
checkbox when I need it to be disabled. So I have code that sets the
Checked status back to what it originally was before the user clicked
on that node.

The problem is that my code works fine, but that as soon as the event

About WTSEnumerateSessions

oli.dune — Mon, 21 Sep 2009 07:56:06 +0000

Hi there,

I try to use the API Function WTSEnumerateSessions to get a list of Terminal Server Sessions.
Of course, it doesn't work quite well, so any help would be highly appreciated.

Look at the here-attached piece of code.
At line 64, replace "TerminalServerName" by a valid one and see what happen.
Apparently we have a valid handle to the server, the WTSEnumerateSessions returns the correct number of sessions, but I can't analyze the list of SessionId/Name/State.
