Basically when you close a tab TabPanel completely destroys it by default (and you can’t reopen closed tab).

To override this behavior add autoDestroy: false to your TabPanel settings object.

But when you try to close a tab you will see  something like this:

That is, tab header is disappeared but the body still visible.

The problem is that you should process remove operation by yourself. Especially if you still want to hide tab body after closing the tab. To do this add two event handlers:

listeners: { 
            remove: function(tp, c) { 
                c.hide(); 
            }, 
            add: function(tp, c) { 
                c.show(); 
            } 
        }

AG_E_UNKNOWN_ERROR

Check all namespace declarations in your Generic.xaml.  If you find something like this:

xmlns:local="clr-namespace:Your_namespace" you should add assembly reference as well:

xmlns:local="clr-namespace:Your_namespace;assembly=Your_assembly"

AG_E_PARSER_BAD_TYPE

Maybe you forgot add reference to assembly(and all its references) with custom control?

If you come(as i do) from SQL world the first thing about indexes you may ask about is auto incremented indexes. Personally i used it as an unique id in relationships such as author->article. However in MongoDB we can use extremely useful built-in, auto generated, unique ids (such an id always appended to the document with key “_id”).

In SQL word id is usually an 4 byte integer, but in Mongo it’s 12 bytes long.

According to the documentation(http://www.mongodb.org/display/DOCS/Object+IDs) ObjectId generator uses increment.

Anyway, some very interesting links:

http://jira.mongodb.org/browse/SERVER-195

Very detailed discussion on relations for SQL guys

Note: in mongodb-csharp ObjectID type is called Oid.

UPDATE

Although ObjectIds are unique you can’t (at least not always) use it for (date) sorting. If you insert records from many machines (or processes) MongoDb doesn’t guarantee that they will constantly grow since internally it uses memcmp function to compare _ids

When the _ids compared memcmp firstly compares time when they created. Usually ObjectID generator have 1 second resolution. If time is the same then machine ids compared. In mongodb-csharp driver for example, machine id is the first 3 bytes of HostName md5 hash. As you can see the result of comparison even at this point is unpredictable.

When i tried to install latest Windows 7 drivers on my PC(currently running on MS Server 2008) I saw the following message “The operating system is not supported by …”. How to trick the installer? Well, solution comes from this post. Simply we need to open unpacked installer in Orca – a tool for MSI installers editing and delete some version checks.

• Invalid property value. bodyStyle: 'background-color: <-space_here#dfe8f7;'. Without space it works perfectly. You can find bodyStyle setting in ExtJs control constructors.
• Unkown runtime error Ext.DomHelper.overwrite("_id_here_", '       ');. You cannot set innerHTML of table in Explorer directly. Use deleteRow/appendRow methods.
• Invalid source HTML for this operation (also known as Unknown runtime error) $('span').innerHTML += <div>...</div>''. You cannot insert a block element inside a non-block element

For me, these errors became a revelation =). Mainly because of the fantastically useful error messages.

And very nice pages about using Latex with Emacs(in russian) 

Here the script:

===========================================

#!/bin/bash

NEWARGS=""

while [ $# -gt 0 ]
do
NEWARGS="$NEWARGS $1"
shift
done

mono /usr/bin/fsharp/bin/fsc.exe $NEWARGS

=============================================

Here we just assembly command line back to one string

it assumses that you have fsharp installed in /usr/bin/fsharp.

Create a file named fsc in /usr/bin (for example). Make in executable chmod +x /path_to_fsc. And now you can call just fsc <your_args> instead of mono fsc.exe <your_args> (i assume that you add /usr/bin/fsharp/bin to $PATH)

With help of this toy script i've compiled http://www.piotrzurek.net/2009/07/11/worlds-first-f-web-browser-runs-on-linux-using-gtk-and-webkit/. And the browser works great!.
