Get all replies to a discussion

shehan — Sat, 10 Oct 2009 15:40:00 GMT

A discussion list in unlike a normal list in that it consists of two content types - a Discussion content type that maps to the discussion topic and a Message that maps to all replies to the topic. If you examine the Discussion content type you’ll see that its inherited from the Folder content type.

The reply contains a field called ‘ParentFolderId’ and as the name suggests it holds the ID of the discussion topic. So naturally if you were to do a query on the list for all items with the same ParentFolderId you would expect the query to work. However, since the topic is of a folder content type and the replies are contained within the ‘folder’ you would need to set the queries ViewAttributes property to "Scope='Recursive'" for it to return results.

Below is an example using the object model:

SPQuery query = new SPQuery();

query.ViewAttributes = "Scope='Recursive'";

StringBuilder queryString = new StringBuilder();

queryString.Append("         <Where>");

queryString.Append("              <And>");

queryString.Append("                        <Eq>");

queryString.Append("                             <FieldRef Name=\"ContentType\" />");

queryString.Append("                             <Value Type=\"Text\">Message</Value>");

queryString.Append("                        </Eq>");

queryString.Append("                        <Eq>");

queryString.Append("                             <FieldRef Name=\"ParentFolderId\" />");

queryString.Append("                             <Value Type=\"Number\">99</Value>"); //NOTE: change this to the value you need

queryString.Append("                        </Eq>");

queryString.Append("              </And>");

queryString.Append("         </Where>");

query.Query = queryString.ToString();

DataTable replyTable = discussionList.GetItems(query).GetDataTable();

Deploying Web Parts to farms with more than 1 WFE

shehan — Tue, 02 Dec 2008 09:50:47 GMT

If you're developing webparts using VSeWSS and going to run the setup.bat that that VSeWSS creates, you might need to modify the deploy solution line before running it.

The deploysolution instruction that VSeWSS adds contains the -local argument. This is all good if you're going to run it on an implementation with only 1 WFE, but for farms with 2 or more WFE's then you will need to change -local to -immediate.

I also make it a habit to call the execadmsvcjobs command before and after adding and deploying.

Manually uninstalling WSS

shehan — Thu, 24 Jul 2008 03:04:33 GMT

Had a situation the other day where, after playing with the different installing options, WSS would not uninstall. Even running the repair option was of no help.

Searching the net for solutions I came across this.

Here are the steps I did:

Disable and Stop the following services (If any):

Windows SharePoint Services Administration
Windows SharePoint Services Search
Windows SharePoint Services Timer
Windows SharePoint Services Tracing
Windows SharePoint Services VSS Writer

Backup and then delete the following registry hives:

HKLM\Software\Microsoft\Shared Tools\Web Server Extensions\12.0
HKLM\Software\Microsoft\Windows\CurrentVersion\Uninstall\WSS

Delete the following folders:

C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\12

Reinstall IIS

Drop the Config and any Content DB's created

After following the steps above you will notice that the entry for WSS in Add & Removed Programs is no longer there. Now you can go-ahead and run the installation again.

Truncate the characters displayed in a blog post

shehan — Tue, 08 Jul 2008 21:35:04 GMT

This is how to reduce the number of characters displayed in a blog post on the default.aspx page of a blog site created from the OOTB SharePoint blog template.

Open up the site in SharePoint Designer
Open the default.aspx and switch to Code View
Perform a Find & Replace for the following:
- Find-
  - ```
  &lt;Field Name="Body"/&gt;
```
- Replace-
  - ```
  &lt;Limit Len="99" IgnoreTags="TRUE" MoreText="..."&gt;&lt;Column Name=&quot;Body&quot;/&gt;&lt;/Limit&gt;
```

This would limit the number of characters to 99 and display the text contained in the MoreText attribute as the last characters. Check out this for more info on the Limit element.

Do remember to back up the page before attempting this just in case.... ;)
