dotnet web services enhancements:
Here's my situation.
I've got an existing VB6 app that is consuming several web services written in VB2005 (via the SOAP toolkit 3). I need the app to be able to download updates. Currently the VB6 app calls a web service to determine whether an update is available. Initially I was thinking I would implement this via SOAP attachments--my understanding is that I would have to use WSE on the server side (the side written in .NET)--will I be able to make that work since the client side (VB6) is using the SOAP toolkit? If so, I could really use some example code.
Thanks Pablo. Unfortunately, I can't be dependent on the client running
Windows XP--otherwise I would definitely be using the App Updater Block. The VB6 app is a product that we sell and is in fairly wide-spread use. So... am I basically limited to writing my own downloader using the wininet.dll or the Inet control? [quoted text, click to view] "Pablo Cibraro [MVP]" wrote:

Pablo,
Was I correct in my previous post in that using the app updater block would require the client to be on XP? What exactly would be the system requirements on the client side? [quoted text, click to view] "Pablo Cibraro [MVP]" wrote:

Hi Brandon,
SOAP attachments (MTOM) is the right technology for scenarios where you have to download or upload files with a web service. (Due to the optmization on the network traffic) However, and unfortunately, it does not work with the SOAP toolkit. (This tool kit was developed a couple of years ago and it does not support any WS-* protocol). If your solution to download the updates is working, I do not see a real reason to change it. If you still want to use MTOM, you might develop some kind of download manager in .NET using that technology, and this manager will be responsible to update your VB6 applications. (Microsoft already provides two solutions for this, Click Once or the Application Updater in Enterprise Library).

Hi Brandon,
In order to run the Application Updater, you need to have the .NET framework installed on the client machine. The .NET runs without problems on XP, but I am not sure if you want to install the .NET framework as well. Regards, Pablo Cibraro.
