when I tried to create a new document based on a custom document content type. I received this error:

The document information panel was unable to load

The fix to ressolve this issue is to copy IPEDINTL.DLL

C:\Program Files\Microsoft Web Designer Tools\Office12\1033\IPEDINTL.DLL
to
C:\Program Files\Microsoft Office\Office12\1033\IPEDINTL.DLL

Afterwards word opened and displayed the panel and everything is working like a charm again

Good luck!

You can implement customactions in your own custom SharePoint page. This enables you to create your peage and afterwards,change or edit the links from within a feature.

Example:

A) In MyCustomPage.aspx

ID="GeneralLinks"
Location="MyApplication.Settings"
GroupId="MySettings"
/>

B) define in a feature this custom action:

GroupId="MySettings"
Location="MyApplication.Settings"
Sequence="1"
Title="My Item Settings"
Rights="ManageWeb">



C: Parsing {STRING}

As you can see there are 2 substrings that need to be parsed with the context. This is the place where OnAddLink enters the scene.

This is wat reflector told me:
public event EventHandler AddLink;

In other terms when we change our FeatureLink like this:
ID="GeneralLinks"
Location="MyApplication.Settings"
GroupId="MySettings"
OnAddLink="OnAddMySettingsLink" />
/>

and in the code behind we create our eventhandler:

protected void OnAddGeneralLink(Object sender, AddLinkEventArgs e)
{
e.Link.NavigateUrl =
e.Link.NavigateUrl.Replace("{MYITEMID}", m_id);
e.Link.NavigateUrl =
e.Link.NavigateUrl.Replace("{LISTID}", m_listID);
}
e.link returns a hyperlink webcontrol object that you can manipulate as you like.
