Developing with VS 2005

by | Sep 28, 2006

Extending MS CRM 3.0 is normally done using Visual Studio 2003 and this is also the only supported development environment. However, it is possible to develop using VS 2005 as well. Some things have to be considered.

.NET 2.0 will work fine for external web applications using the CRM Webservice (not very strange since the webservice is generic)

.NET 2.0 will probably also work fine when developing workflow dll:s, but it is not supported. At least it worked when I tested Hello World! 🙂

.NET 2.0 will not work when developing callouts. However, there is a great description of how to develop these in VS 2005 anyway but for .NET 1.1. Beware that you cannot use specific .NET 2.0 functionality.

Here is the site: http://blogs.msdn.com/arash/archive/2006/08/25/719626.aspx

A good thing with this is that the standard TDT can be used when developing customizations. I am no licensing expert, so make sure it’s within your licensing agreement.

Odd SQL Reporting Services Error…

by | Sep 27, 2006

I was working with a custom report today and I had a very strange error which I have noticed that several others also seem to have, both with SQL Reporting Services and other .NET applications. The report I was making worked fine, but when I tried to deploy it to the site, I got the following error:

“Length cannot be less than zero.”

When I dubbel-clicked it in VS2003 (yes, I am still using it), the sourcefile of my DataSource was shown, and there was nothing wrong there…

Well, I tried lots of different things, restarting, trying to deploy to another server but the error was still the same and I could see the report was working fine i Preview mode.

Well, after a while I got fed up with it, and just tried to install the rdl manually on the reportserver (using the update function, in the properties tab of the report). It worked!

Hence, there seems to be some error in the deployment of reports in SQL Reporting Services. If you get this error, try to bypass it, your report might not be the problem after all.

Anyone reading this that knows why the deployment didn’t work? I’d like to know!

Web and Outlook mixup

by | Sep 27, 2006

As some of you might have noticed, if you have the Outlook desktop client installed and Outlook open, and then open CRM using IE, you will loose some web-specifics like the “Settings” menu and other addons specified in the sitemap or isv.config.xml as “web”.

This is due to the fact that these files are downloaded to the client by IE when Outlook is started and these are then cached by IE. When the same URL is opened, IE recognizes these files, and does not download any new files, hence you get the Outlook-client specific.´

How to solve this? IE bases its caching on the url so you just have to install the crm-outlook-client to one url and use the webclient for the other. Note that you can even use the IP adress as one of the url:s, since IE doesn’t resolve the name when checking for cache-hits.

Use AllColumns

by | Sep 22, 2006

When retrieving data from the CRM webservice, part of the
RetrieveRequest-object needs to have the required columns specified. In
many of the examples this field is specifically set to the columns
needed, which is the most “correct” way of retrieving the data. However,
if you aren’t experiencing performance problems the easiest way is to
use the AllColumns-class.

In short:

RetrieveRequest retrieve = new RetrieveRequest();
retrieve.ColumnSet = new AllColumns();

This is probably old news to all of you who have coded a bit. But I
thought I might write a bit about it anyway, since not all people are
experts at birth.
