Sharepoint 2010 資源預約行事曆

使用Sharepoint 2010 資源預約行事曆後,發現無法在同一行事曆上直接顯示所有預約狀況,使用上很不便,測試好久始終無法修改,於是詢問高手後,原來是有設定需修改。

重點
1.至該行事曆清單設定
2.一般設定->標題、描述與導覽
3.是否將此行事曆用於資源預約? -> 否 ->存檔
4.回清單設定 -> 內容類型 -> 變更新的按鈕順序與預設內容類型 -> 選預約(取消事件勾勾) ->確定
5.搞定

修改Sharepoint資源預約的工作區選項隱藏

修改Sharepoint資源預約的工作區選項隱藏
用sharepoint designer 到網站集合(EX: fx-xxzs/sites/xxxx)
左方功能列選內容類型,
因行事曆屬清單類型,故於右方畫面上找尋清單內容類型
然後選事件,再來在自訂當中選擇編輯內容類型欄
在此視窗下選擇工作區(要修改的那個欄位),然後選上方工具列管理網頁,再將其隱藏。

複習IP網段

Binary Number System
2^0 = 1
2^1 = 2
2^2 = 2 x 2 = 4
2^3 = 2 x 2 x 2 = 8
2^4 = 2 x 2 x 2 x 2 = 16
2^5 = 32
2^6 = 64
2^7 = 128
2^8 = 256
Binary system number is based on power of two (2^n).

1 x 2 = 2 | half the size
2 x 2 = 4 | A
4 x 2 = 8 | |
8 x 2 = 16 | |
16 x 2 = 32 | |
32 x 2 = 64 | |
64 x 2 = 128 V |
128 x 2 = 256 double the size |

In terms of subnetting,
1   = /32 = 255.255.255.255
2   = /31 = 255.255.255.254
4   = /30 = 255.255.255.252
8   = /29 = 255.255.255.248
16  = /28 = 255.255.255.240
32  = /27 = 255.255.255.224
64  = /26 = 255.255.255.192
128 = /25 = 255.255.255.128
256 = /24 = 255.255.255.0

In terms of IP address quantity
/32: 2^0 = 1                        =   1 IP address within the subnet
/31: 2^1 = 2 of /32 = 2 x   1 =   2 =   2 IP addresses within the subnet
/30: 2^2 = 2 of /31 = 2 x   2 =   4 =   4 IP addresses within the subnet
/29: 2^3 = 2 of /30 = 2 x   4 =   8 =   8 IP addresses within the subnet
/28: 2^4 = 2 of /29 = 2 x   8 =  16 =  16 IP addresses within the subnet 
/27: 2^5 = 2 of /28 = 2 x  16 =  32 =  32 IP addresses within the subnet
/26: 2^6 = 2 of /27 = 2 x  32 =  64 =  64 IP addresses within the subnet
/25: 2^7 = 2 of /26 = 2 x  64 = 128 = 128 IP addresses within the subnet
/24: 2^8 = 2 of /25 = 2 x 128 = 256 = 256 IP addresses within the subnet
Side Note:

Some people refer the xxx.xxx.xxx.xxx notation as octet (8-based number system). There are four octets in the notation. To separate the octets, there are dots between them. I call them 4-tuple octet.

For /24 to /32 subnets, the 1st three octets remain the same. The only octet that changes is the 4th octet (the last octet).

Subnet Mask

Subnetting always relates to something called Subnet Mask. Subnet Mask is the way an IP address represent which subnet it is under.

To show you how a subnet mask looks like, let's review the previous table.
1   = /32 = 255.255.255.255
2   = /31 = 255.255.255.254
4   = /30 = 255.255.255.252
8   = /29 = 255.255.255.248
16  = /28 = 255.255.255.240
32  = /27 = 255.255.255.224
64  = /26 = 255.255.255.192
128 = /25 = 255.255.255.128
256 = /24 = 255.255.255.0

As mentioned, there are octets separated by dots that I called 4-tuple octet. This 4-tuple octet is commonly known as Subnet Mask.

Another format of displaying subnet mask is by using CIDR (Classless Inter-Domain Routing) format. Where the 4-tuple octet format is shown on the above table rightmost column, the CIDR format is shown on the above table leftmost column. To clarify, check out following table.
