Consume Web Map Service (WMS) with VB6

Hi All:

Anyone have any experience using WMS in VB6?
I'm new to WMS and have no experience at all in this area.

I have access to a wms server, and I can easily
load the images in IE using a http request,
but I was wondering how to comsume and display the
images in a VB6 app?

Doug.

I was able to consume the WMS using the webbrowser control,
but now I need to extract the map image from the web document;
anyone know how to do that?

Hi Doug,

SOAP is where it's at. microsoft.public.msdn.soaptoolkit

Stan Shultes wrote an article for VSM on the subject. See: Create and
Consume XML Web Services
Create a simple Web service in VB.NET, and build a VB6 desktop client.
(http://www.fawcette.com/vsm/2002_07/magazine/columns/gettingstarted/)

Easier, though (IMO) using .NET. Web services and .NET go together.

Hi Dick:

As it turns out, a simple API call is all I needed.
Because of the way the WMS request is formatted/handled,
I can download the image directly to disk using the same
api call that Veign uses to extract images from HTML
documents:

Private Declare Function URLDownloadToFile Lib "urlmon" Alias "URLDownloadToFileA" _
(ByVal pCaller As Long, ByVal szURL As String, ByVal szFileName As String, _
ByVal dwReserved As Long, ByVal lpfnCB As Long) As Long

I tried the same thing with the Microsoft terraserver and it works as well.

Doug.

Hi Doug,

I haven't actually tried the MP Webservice. I did attempt to signup for a
trial/developer account (or whatever it was called), but something went
wrong (MS Blackhole?), and I haven't gotten back to it.

Licensing for it is a real bugaboo (IMO).

Regards, Dick

Have you look into the SOAP toolkit at all? I would think it would do what
you want.

No I haven't... but I will.

I am able to view the image in the webbrowser control...
you wouldn't happen to know how to get the image
out of the control document?

Doug.

I noticed Veign's post in another and low and behold --
he has code on his web site to extract images from the document!

Thanks Veign!

Doug.
