Win32 API samples

This collection of code snippets used to be hosted on www.global-shared.com.
It is an old collection: it all began in 1996 or 1997, when Progress 8 was new and many of us were still using Windows 3.1 !!
Unlike wine or paintings, program code doesn't get better when it ages. You can find fragments that can be improved because Microsoft continuously expands their API, or are outdated because Progress has added features to the ABL so we don't need to use the WIN32 API anymore.

Hosting a Progress Application in a .Net Application

Hi there,

Is there a way to host a Progress 4GL app in an HTML page or in a .NET application. Is it possible to wrap it as an ActiveX control, or are there perhaps tools out there that provide some form of wrapper to turn it into a control?

Thanks for your help.

About WTSEnumerateSessions

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.

Thank you very much in advance!

I cannot find any download link for msgblst32.ocx. Please help!!


.NET + OpenEdge Webservices using ProDataSet

We are trying to create an application with a thought of SOA, for this we
have selected .Net UI and progress web services using prodataset.

Problem is that .net client is not able to find prodataset reference in
services which are taking dataset as input parameter (they need to create
an object of that type to pass to this service).


How to add a colored square in the titlebar through api

Sometimes it's neccessary to add a Caption in the titlebar to give extra information to the user of your application. The attached file does this, and makes sure the window got redrawn when windows triggers arive.
As you can see, many instances of msgblst32 are added on this window. The goal is to make it more the controlling window which always catches the events on the underlaying session applications. As every window needs its own ocx, I provided 40 instances which are hopefully enough to maintain every window.

How to get the 'WTSSessionID' out of the WTSQuerySessionInformation function??

I need to get the 'SessionID' from a Terminal Server Session.
I've already found a Progress example how to use the 'WTSQuerySessionInformation' to get the username (= WTSInfoClass = 5 => pointer to a null-terminating string).

To get the SessionId I need to call the same function but with the WTSInfoClass = 4 (= pointer to a ULONG variabele)
How can I do this??? I've changed the parameter from 5 to 4 but I don't get a result!!

I also want to use the same function but with the WTSInfoClass = 23 (= WTSClientInfo => pointer to a WTSCLIENT structure)

Step 1: db2Excel Collects tables from the database and makes them available for selection.
(if needed for schema preview, you can edit the source code to view system tables)
