Thank you Thomas. I followed the two references you gave me; the Windows Imaging Component is relevant to what I'm looking for, but it seems too complicated for what I though would be a simple task. I will study it a little bit harder and look for alternative libraries as you suggested. Thanks again.

How to read File Properties
Hi all, Recently I'm dealing with lots of data that come as images that have important metadata for us. The metadata are packaged as file properties, visible when you right click on an image in Windows explorer. I need to read access this from a Visual Prolog program. How can I easily do this? I'm c...

Uploading files to a website
Hello,
I need to upload some files to a website using VP. Related to this I see some references to the VPcURL package in this discussion forum. How do I access it?
Thanks

[byval] attribute
Hi Thomas,
I understand what the [in] and [out] attributes do in predicate arguments, but not [byval]. What does it mean and how would I use it?

COM-based SMS library for GSM phones
Hello Forum, I plan to build a Prolog application for sending/receiving short messages via a modem. I have searched the internet and identified many potential libraries. Before I try any of them, I would like to find out if any member of this forum has used or can recommend a specific library that h...

Thanks Thomas. Now it works fine.
Just curious.... how much memory is allocated by the statement
The Prolog documentation refers to #Count but this is applicable to

Thomas, Now I understand what you meant when you said:- However the resulting "Disp" object is not as easy to use as in VB. Here is what I want to do in VB ... set disp = getobject(,"Excel.applicaion") 'To display the name of the application, using the name property msgbox disp.name .... Here is how...

How do you get the active object?
Thomas,
In VB I used the following statement to obtain the active Excel application object
How would I use the comCreation:: libray to achieve the same result in Visual Prolog?

Hello Carlesius. Welcome. I have not checked to see where this is documented but from my experience in Visual Prolog, this name := none(), assigns the none() value to the name fact And this name = none() is a unification that would cause the clause to succeed if the name fact is set to none ; otherw...

ODBC error in pfc\odbc\odbcStatement.pro and way forward
Hi Thomas, After making some minor change to my code, my application started to behave in a most unexpected way. The seemingly innocuous change I made was to access data by field name rather than by a column number, as I was not sure the order in which the columns were returned by a fetch. So, I mad...

Gridview control
Hi,
I have a problem that I think a Gridview control would be part of the solution. Is there such a control in Prolog? I don't seem to find any.
