Simulating IE4+ Syntax in NN6

We can simulate different properties which are not supported by NN6 and are supported by IE. In other words we can create new properties which are not supported by NN6 for any type of object. For example "all", "innerText" and "outerHTML" are not supported by NN6. We can simulate them.

Simulating "all": (for example "document.all")
the Node static object is the object from which all elements are derived. That object’s prototype is enhanced here because you have to make sure that all nodes, especially the document node, can acquire the all property.
Here is the code:

if (!document.all)
{
Node.prototype.__defineGetter__(“all”, function()
{
if (document.getElementsByTagName(“*”).length)
{
switch (this.nodeType)
{
case 9:
return document.getElementsByTagName(“*”);
break;
case 1:
return this.getElementsByTagName(“*”);
break;
}
}
return ""
}
)
Node.prototype.__defineSetter__(“all”, function() {})
}


The anonymous function first establishes a branch in the code only for the object model if it supports the wildcard parameter for the document.getElementsByTagName() method. The function then performs slightly different extractions depending on whether the node is the document (type 9) or an element (type 1). If the all property should be queried for any other kind of node, the returned value is an empty string. Each time the all property is accessed, the
anonymous function executes to pick up all elements nested inside the current node. Therefore, the collection returned by the all property is always up to date, even if the node structure of the current object changes after the document loads.

Unable to delete Shared Services Provider in SharePoint (MOSS)

Sometimes The SSP you create in MOSS are not created properly. This can be result of interruption while SSP was being created or in result of bad migration from SPS03 or MCMS to MOSS. Symptoms: 1. In left nav of SharePoint Central Administration, the name of your new SSP will not render rather, it will show up as text. 2. If you try to delete that from the Central Admin, the Delete option is disabled. Resolution: You should delete the SSP using stsadm command line tool (NOTE: My SSP's name is "SSP" which is specified after "title" in command: C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\BIN>stsa dm -o deletessp -title "SSP" However, if you have any dependencies, you will have to delete them first or you will get following error when you try deleting it through command line tool: An object in the SharePoint administrative framework, "SharedResourceProvider Na me=SSP Parent=SPFarm Name=SharePoint_Config&quo

The server was unable to process the request due to an internal error. For more information about the error, either turn on IncludeExceptionDetailInFaults (either from ServiceBehaviorAttribute or from the configuration behavior) on the server in order to send the exception information back to the client, or turn on tracing as per the Microsoft .NET Framework 3.0 SDK documentation and inspect the server trace logs.

  While configuring the SharePoint 2010 for Forms Based Authentication, I encountered above error. To get the problem, I had to change “IncludeExceptionDetailInFaults” to true somewhere. But WHERE? Here is what solved my problem: Go to following path: 1. C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\WebServices\SecurityToken 2. Open Web.config there. 3. Add following in the “behaviors > serviceBehaviors > behavior” node. <serviceDebug includeExceptionDetailInFaults="true"/> Now try to login and see what error it gives, off to a next error

Cannot add a SimpleContent column to a table containing element columns or nested relations

Recently I ran into a problem while dealing with DataSets. I was adding a colum to an XSD through Visual Studio desinger and it kept failing with following error: Cannot add a SimpleContent column to a table containing element columns or nested relations. This is a known issue. However, the solution is not well known :) To be simple and streight forward, I tell you the solution which I tried and it worked, 1. Note down the column names, datatypes and relationships of the table. 2. Delete the table. 3. Add new table and add columns to it. 4. Redefine relationships. Best of luck.
