If you get the following error Method ‘post’ of object ‘IOWSPostData’ failed, you can fix it by doing the below:

Do a search on you C: drive for a file named: EXPTOOWS.XLA

Open it and Enable Macros

Select the Developer tab and the Visual Bacis or press ALT+11. Same result. You are ready to alter the file.

Search for:

lVer = Application.SharePointVersion(URL)

Add a new line just below:

lVer = 2

Save and exit.

Now try the import again & it should work.

NOTE: this is a problem with excel as opposed to Sharepoint so this would need to be done on all workstations requiring the ability to import Excel 2007 spreadsheets as custom lists.

If you have enabled anonymous access on your Sharepoint farm and you still get prompted for a login when trying to access a list, it is most likely that your list exists in a ‘Publishing Site’.

This is because by default all publishing sites have a feature called ‘ViewFormPagesLockdown’ activated. This basically provides extra security for internet facing Sharepoint sites by stopping anonymous users viewing pages like AllItems.aspx etc.

If you want anonymous users to be able to view such pages you need to disable ‘ViewFormPagesLockdown’

1 Remove all anonymous access from the site.
2 Deactivate the ViewFormPagesLockdown Feature
3 Make sure that the list inherits its permissions from its parent.
4 Do an IISreset and close all browsers.
5 Wait 60 seconds or so for everything to start backup
6 Turn anonymous access on at the site level
7 Close the browser.
8 Browse to the website as anonymous user.
9 Click on a navigation link to browse to the list in question
10 You should now be able to browse list items as an anonymous user.

Activate Feature:

stsadm -o activatefeature -url -filename ViewFormPagesLockDown\feature.xml

De-Activate Feature:

stsadm -o deactivatefeature -url -filename ViewFormPagesLockDown\feature.xml

This easiest way is to use the URL below & insert your list GUID

http://servername/site/_vti_bin/owssvr.dll?Cmd=Display&List=*YOURUNIQUELISTID*&XMLDATA=TRUE

To get the GUID of the list you need to go into the list & click ‘Settings’ -> ‘List Settings’. Now if you look at your URL you will see something like:

/_layouts/listedit.aspx?List=%7B7B476F98%2D1075%2D4A6D%2D8F63%2D4C754B3F41FC%7D

The URL is encoded so you will need to replace “%7B” with “{” and “%7D” with “}” and “%2D” with “-” so the end result would look something like: {7B476F98-1075-4A6D-8F63-4C754B3F41FC}

This SharePoint feature allows you to quickly import data from a CSV file or a SQL stored procedure to any custom SharePoint list.

Once you have added the solution to your farm and activated it on your site collection an additional menu option will be available on the Action menu of each custom list that will take you to the import CSV or SQL page.

Simply select which option you want – either import from a CSV file or import from a SQL stored procedure. Next, browse to the CSV file or enter the SQL connection and name of the stored procedure and hit the Import button.

There is a check box option to delete all items from the list before doing the import which is not selected by default.

If you’re frustrated by the lack of charting ability in Sharepoint / MOSS take a look at Visifire

Using Silverlight, The Dataview Webpart & Visifire you can start charting your list data within minutes with some very smart charts!

Many times during a project, you hit a requirement to have the ability to display an org chart on your SharePoint portal, and because there are many options to do this, it is difficult to know what approach is best for your particular scenario.

Here is a quick way of developing an org chart that the business users can update themselves! There are many options in terms of what data source you can use, such as Excel, MS Access, SQL Server or any OLEDB or ODBC data source.

For this scenario, we simply configure the Visio 2007 Org Chart to retrieve its data from a SharePoint List. The possibilities are endless in terms of how that data gets populated into the SharePoint List as well. For instance, you can write some code to retrieve and cleanup some data before programmatically importing it into the List.

At first glance this doesnt look possible OOTB but it is, just not very obvious!

The way to achieve this is to:

1) Create a list at say Site Collection level which contains a column with the data in you want to use on another site.

2) Now create a Lookup column at Site Collection Level which is pointing to the data from the above list that you want to use.

3) Now you can add that column, to any list, on any site, throughout the site collection.
