SharePoint Approval workflow restart on Edit Item

This is a very old and very common requirement. But after working on SharePoint since last 3 years this is the first time I came around with such problem and it is very surprising for me as well that why I never came across such problme in past.

1. I never came across such requirement
2. HotFix is already installed on the servers.

Problem Statement

I have one Document Library called : Company News, I have attached a sequential workflow with Approval and Publisher group with On Add and Edit items. Now whenever a new item is created in document library it starts the workflow and approver approves it.

Once approver approve the item, it goes to publisher being asequential workflow for their approver. But since publisher is also approving the item, it is still showing an item as InProgress.

Solution

Download the HotFix from http://support.microsoft.com/default.aspx?scid=kb;en-us;955586

Session Timeout in SharePoint

Since long I have a question that how can I implement a session time out in SharePoint sites. But i never explore as there is no such requirement in any of my project till now.

Suddenly the requirement came and we have to suggest a way to do that with the minimal efforts. And after searching on google i found this and this..., though still we haven't implemented it :(

I am giving you the easiest way directly here to implement that, edit your master page and add the below script in javascript block.

function MySiteTimeOut()
{setTimeout("SessionTimeOut()", 300000);}

function SessionTimeOut()
{document.execCommand("ClearAuthenticationCache");}

This is the same function called when you click on Sign-out in SharePoint site.

Hide WebPart at run time

In one of my project we had a requirement to hide the WebPart based on the logged in user's department-id. We are not able to use Audiance Targeting to achieve this cuase we were getting user's department id using webservice from 3rd party system only.
What I did, I wrote my custom RSS Viwer WebPart with custom field. And Thanks to SharePoint Developer Center, I found a solution to hide the webpart at runtime very easily.
See the Code Snippet below.
protected override void OnPreRender(EventArgs e)
{
if(your condition)
HideWebParts();
}

private void HideWebParts()
{
if (this.WebPartManager.DisplayMode != System.Web.UI.WebControls.WebParts.WebPartManager.EditDisplayMode
&& this.WebPartManager.DisplayMode != System.Web.UI.WebControls.WebParts.WebPartManager.DesignDisplayMode)
{
for (int i = 0; i <>
{
if (WebPartManager.WebParts[i].Title == this.YourCustomWebPartName.Title)
{
WebPartManager.WebParts[i].AllowHide = true;
WebPartManager.WebParts[i].Hidden = true;
} } } }
