部落格使用table出現一堆

問: 我在文章裡放入表格時，出現了多餘的空白行。 我要如何刪除這些空白行？
答: 空白行是因為 Blogger 會在您文章的每行結尾插入<br />標記，這可在 設定 -> 格式 -> 轉換分行符號 中設定

visual studio常用熱鍵(hotkey)

我個人常用的visual studio 2008熱鍵一覽表

Table 1: Visual Studio Hotkeys/Default Keybindings/Shortcut keys

基本設定
清單顯示熱鍵	Tools -> Customize... -> Toolbars -> Show shortcut keys in Screen Tips
源碼顯示行號	Tools -> Options... -> Text Editor -> C/C++ -> Display -> Line numbers
Build/Compile
Build	CTRL+SHIFT+B or F7
Build	CTRL+SHIFT+B or F7
Build	CTRL+SHIFT+B or F7
Build	CTRL+SHIFT+B or F7
Debugging/Running
Start with Debug	F5
Debug.StartWithoutDebugging	Global::Ctrl+F5
Toggle/Untoggle Breakpoint	F9
Navigation
Edit.GoToDefinition	F12	Go to definition
Edit.GoToReference	Shift-F12	Finds a reference to the selected item or the item under the cursor.
Edit.GoToDeclaration	Ctrl-F12	Displays the declaration of the selected symbol in the code.
Edit.GoTo	Global::Ctrl+G	Displays the Go to Line dialog. If the debugger is running, the dialog also lets you specify addresses or function names to go to.
Edit.GotoBrace	Ctrl-]	Moves the cursor to the matching brace in the document. If the cursor is on an opening brace, this will move to the corresponding closing brace and vice versa.
Edit.DocumentEnd	Ctrl-End	Moves the cursor to the end of the document.
Edit.DocumentStart	Ctrl-Home	Moves the cursor to the start of the document.
Edit.ToggleBookmark	Ctrl+K, Ctrl+K or Ctrl+F2	Sets or removes a bookmark at the current line.
Edit.ClearBookmarks	Text Editor::Ctrl+K, Ctrl+L	Removes all unnamed bookmarks in the current document.
Edit.NextBookmark	Text Editor::Ctrl+K, Ctrl+N or F2	Moves to the next bookmark in the document.
Edit.PreviousBookmark	Text Editor::Ctrl+K, Ctrl+P	Moves to the previous bookmark.
View.TaskList	Ctrl+\, Ctrl+T	Displays the TaskList window, which displays tasks, comments, shortcuts, warnings, and error messages.
Edit.ToggleTaskListShortcut	Ctrl-K, Ctrl-H	Sets or removes a shortcut in the tasklist to the current line.
Edit.ScrollLineDown	Ctrl+Down Arrow	Scrolls text down one line but does not move the cursor. This is useful for scrolling more text into view without losing your place. Available only in text editors.
Edit.ScrollLineUp	Ctrl+Up Arrow	Scrolls text up one line but does not move the cursor. Available only in text editors.
Edit.WordNext	Ctrl+Right Arrow	Moves the cursor one word to the right.
Edit.WordPrevious	Ctrl+Left Arrow	Moves the cursor one word to the left.
Edit.SelectCurrentWord	Ctrl-W	Selects the word containing the cursor or the word to the right of the cursor.
Code View
Edit.CollapsetoDefinitions	Ctrl+M, Ctrl+O	Automatically determines logical boundaries for creating regions in code, such as procedures, and then hides them. This collapses all such regions in the current document.
Edit.StopHidingCurrent	Ctrl-M, Ctrl-U	Removes the outlining information for the currently selected region.
Edit.StopOutlining	Ctrl-M, Ctrl-P	Removes all outlining information from the entire document.
Search and Replace
Edit.Find	Ctrl-F	Displays the Find dialog.
Edit.FindinFiles	Ctrl-Shift-F	Displays the Find in Files dialog.
Edit.FindNext	F3	Finds the next occurrence of the previous search text.
Edit.FindPrevious	Shift-F3	Finds the previous occurrence of the search text.
Edit.FindNextSelected	Ctrl-F3	Finds the next occurrence of the currently selected text or the word under the cursor if there is no selection.
Edit.FindPreviousSelected	Ctrl-Shift-F3	Finds the previous occurrence of the currently selected text or the word under the cursor.
Edit.Replace	Global::Ctrl+H	Displays the Replace dialog.
Edit.ReplaceinFiles	Ctrl+Shift+H	Displays the Replace in Files dialog.
Edit.IncrementalSearch	Ctrl+I	Starts an incremental search—after pressing Ctrl-I, you can type in text, and for each letter you type, VS.NET will find the first occurrence of the sequence of letters you have typed so far. This is a very convenient facility, as it lets you find text by typing in exactly as many characters as are required to locate the text and no more. If you press Ctrl-I a second time without typing any characters, it recalls the previous pattern. If you press it a third time or you press it when an incremental search has already found a match, VS.NET searches for the next occurrence.
Edit.ReverseIncrementalSearch	Ctrl+Shift+I	Performs an incremental search in reverse direction.
Edit.FindSymbol	ALT+F12	Displays the Find Symbol dialog.
Edit.QuickFindSymbol	Global::Shift+Alt+F12	Displays the Find Symbol Results window.
Window
Next IDE Window	CTRL+F6 or Ctrl+Tab
IntelliSense
Edit.CompleteWord	CTRL+SPACE or ALT+RIGHT ARROW	Completes the current word or shows the IntelliSense completion list.
Edit.ListMembers	Ctrl-J	Lists members for statement completion when editing code.
Edit.QuickInfo	CTRL+K, CTRL+I	Displays the complete declaration of the identifier under cursor.
Editing
Edit.Comment-Selection	CTRL+K, CTRL+C	Comments selected text.
Edit.Uncomment-Selection	CTRL+K, CTRL+U	Uncomments selected text.
Edit.Cut	Global::Shift+Del	Cut the entire row from the document and past it to the clipboard.
Edit.LineCut	Ctrl-L	Cuts all selected lines or the current line if nothing has been selected to the clipboard.
Edit.WordDeleteToEnd	Ctrl-Delete	Deletes the word to the right of the cursor.
Edit.WordDeleteToStart	Ctrl-Backspace	Deletes the word to the left of the cursor.
Edit.LineOpenAbove	Ctrl-Enter	Inserts a blank line above the cursor.
Edit.LineOpenBelow	Ctrl-Shift-Enter	Inserts a blank line below the cursor.
Edit.WordTranspose	Ctrl+Shift+T	Moves the word containing the cursor after the next word.
Edit.LineTranspose	Shift+Alt+T	Moves the line containing the cursor below the next line.
Edit.MakeLowercase	Ctrl-U	Changes the selected text to lowercase characters.
Edit.MakeUppercase	Ctrl-Shift-U	Changes the selected text to uppercase characters.
Edit.FormatSelection	Text Editor::Ctrl+K, Ctrl+F or Alt+F8	Format the code in the window to be nicely indented.
Edit.Insert	Insert	Toggles between insert and overtype insertion modes.

# 純量陣列以 @ 開頭。
my @array;
my @array=qw(a b c d);

# qw 函數會將其後的每個元素用逗點隔開，效果就像下面這行。
my @array=("a","b","c","d");

# 當然你也可以一個個元素宣告，下面就是存取每一個元素的方法。
# 因為陣列中的每一個元素都是純量變數，所以要以 $ 開頭，
# 剛開始容易搞混，請注意。
$array[0]="a"; $array[1]="b"; $array[2]="c"; $array[3]="d";

# 使用for loop印出陣列內每個元素的值。
