如何寫Google chrome extension

1.安裝開發者專用的Google chrome 版本,升級至Dev or Beta build.

路徑如下:

Windows

Download and run the installer for the desired channel:

Dev channel: http://www.google.com/chrome/eula.html?extra=devchannel
Beta channel: http://www.google.com/chrome/eula.html?extra=betachannel

You'll need to restart Google Chrome to get the update.

2.開始撰寫程式:

參考文件:http://code.google.com/chrome/extensions/getstarted.html

#先產生一個檔案夾

#產生一個內容如下的檔案,並命名為 manifest.json

{
  "name": "GTD-Link",
  "version": "1.0",
  "description": "Some GTD link I used.",
  "browser_action": {
    "default_icon": "icon.png",
    "popup": "gtd_menu.html"
  },
  "permissions": [
    "http://api.flickr.com/"
  ]
}

popup:表示點選這個外掛會跳出網頁 gtp_menu.html

3.開起Browser 擴充功能,點選+ 載入未封裝的程式,選擇剛剛撰寫的檔案

4.載入後,即完成了第一個瀏覽器擴充套件

VMware Esxi 4.0 client 無法在windows 7 中啟動問題

問題描述:
VirtualInfrastructure.Utils.HttpWebRequestProxyK的型別初始設定式發生例外狀況

解決方法:
原始作者:Fernando

1. Obtain a copy of %SystemRoot%\Microsoft.NET\Framework\v2.0.50727\System.dll from a non Windows 7 machine that has .NET 3.5 SP1 installed.

2. Create a folder in the Windows 7 machine where the vSphere client is installed and copy the file from step 1 into this folder. For example, create the folder under the vSphere client launcher installation directory (+%ProgramFiles%\VMware\Infrastructure\Virtual Infrastructure Client\Launcher\Lib+).

3. In the vSphere client launcher directory, open the VpxClient.exe.config file in a text editor and add a element and a element as shown below. Save the file.

3. Create a batch file (e.g. *VpxClient.cmd*) in a suitable location. In this file add a command to set the DEVPATH environment variable to the folder where you copied the System.dll assembly in step 2 and a second command to launch the vSphere client. Save the file. For example,

SET DEVPATH=%ProgramFiles%\VMware\Infrastructure\Virtual Infrastructure Client\Launcher\Lib
"%ProgramFiles%\VMware\Infrastructure\Virtual Infrastructure Client\Launcher\VpxClient.exe"

4. (Optional) Replace the shortcut on the start menu to point to the batch file created in the previous step. Change the shortcut properties to run minimized so that the command window is not shown.

You can now use the VpxClient.cmd (or the shortcut) to launch the vSphere client in Windows 7.

Note that this workaround bypasses the normal .NET Framework loading mechanism so that assembly versions in the DEVPATH folder are no longer checked. Handle with care.

D-sub 轉色差線

最近買了一台 WD mini TV,想說可以用他接LCD看影片,等到拿到東西後,才發現LCD上面根本找不到AV端子孔位,接著上網尋找,終於在PChome看到有賣 VGA轉色差 (Y Pb Pr), 接上後,雖然可以看到影像,可是顏色嚴重偏綠,上網查詢發現一推討論文章,不過我還沒弄懂,暫時先大概紀錄一下網路搜尋到的相關知識做簡單紀錄

VGA 是 R(紅) G(綠) B (藍) H( 水平) V (垂直)
色差是 Y Pb Pr
綠色線似乎是輸出視訊訊號
