visual studio常用熱鍵(hotkey)

2009-07-21T02:32:00.000-07:00

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.

C/C++的const總介紹

2009-06-04T05:57:00.000-07:00

簡單的介紹C中const的用法 1 int main() 2 { 3 const char ch = 'a'; 4 const int a[5] = {1, 2, 3, 4, 5}; 5 int b[5] = {6, 7, 8, 9, 10}; 6 int c[4][4] = {{11,12,13,14},{15,16,17,18},{19,20,21,22},{23,24,25,26}}; 7 const int *p1 = a; 8 int *const p2 = a; 9 const int * const p3 = b; 10 const int ** const p4 = c; 11 12 ch = 'b';//error: ch is const, can't be modified 13 p1 = &a[2]; //ok, *p1 is const, p1 is not 14 *p1 = 5;//error, *p1 is const, a[2] is const 15 *(p1 + 2) = 1; //error, *p1 is const 16 p1 = &b[2];//ok 17 *p1 = 4;//error, *p1 is const 18 p2 = &b[4];//error, p2 is const 19 p2++;//error, p2 is const 20 *p2 = 10;//error, *p2 is not const, p2 is, but a[0] is const 21 p2 = &a[5];//error, p2 is const 22 p3 = &b[1];//error, p3 is const 23 *p3 = 3;//error, *p3 is const 24 p4 = b;//error, p4 is const 25 *(*p4+2) = 10; //error, **p4 is const 26 *p4 = b; 27 printf("%d", **p4); //6, *p4 = b 28 **p4 = 10;//error, **p4 is const 29 30 return 0; 31 } 32 --------------------------------------------------------------------------------------

簡單的介紹C++中const的用法 1 /* 2 * ===================================================================================== 3 * 4 * Filename: const.cpp 5 * 6 * Description: 7 * 8 * Version: 1.0 9 * Created: 06/04/2009 09:01:15 PM 10 * Revision: none 11 * Compiler: gcc 12 * 13 * Author: YOUR NAME (), 14 * Company: 15 * 16 * ===================================================================================== 17 */ 18 #include <stdio.h> 19 #include <stdlib.h> 20 class Ball { 21 static const int ID = 100;//initialize only once, can't modify anymore 22 //const int ID2; //can't modify it anymore, and initialize 23 char *name; 24 int money; 25 mutable int bonus; 26 public: 27 Ball(){ 28 name = (char *)malloc(8); 29 name[0] = 'y'; 30 name[1] = 's'; 31 } 32 int setID(int id){ 33 //ID = 200;//error, ID is const 34 } 35 void showID(){ 36 printf("ID:%d\n", ID); 37 } 38 const char* getConstName() { return name; } 39 char* getName() { return name; } 40 int getMoney() const { 41 //money++;//error, function is const, can't modify any its class member 42 bonus++;//ok, it is mutable, can be used in const function 43 return money+bonus; } 44 }; 45 int main() 46 { 47 Ball b = Ball(); 48 b.showID(); 49 printf("name:%s\n", b.getName()); 50 b.getName()[2]='l'; 51 printf("name:%s\n", b.getName()); 52 //b.getConstName()[2]='l';//error, return const can't modify 53 printf("money:%d\n", b.getMoney()); 54 55 return 0; 56 } 57 --------------------------------------------------------------------------------------

簡單的介紹C++中const templates的iterator用法,還有其中content為const時如何去掉const來呼叫 1 #include <iostream> 2 #include <vector> 3 #include <map> 4 #include <string> 5 6 using namespace std; 7 8 class Symbolic{ 9 public: 10 Symbolic(int v, string e){ 11 value_ = v; 12 expr_ = e; 13 } 14 15 void Print(){ 16 cout<<"value:"<<value_<<", "<<expr_<<endl; 17 } 18 19 void constPrint() const{ 20 cout<<"value:"<<value_<<", "<<expr_<<endl; 21 } 22 private: 23 int value_; 24 string expr_; 25 }; 26 27 void vectorPrint(const vector<const Symbolic *>& v) 28 { 29 /* const_iterator for const template iteration */ 30 vector<const Symbolic *>::const_iterator v_iter; 31 for(v_iter = v.begin(); v_iter != v.end(); v_iter++){ 32 /* make const member to be normal */ 33 const_cast<Symbolic *>(*v_iter)->Print(); 34 /* const class pointer only can call const function */ 35 (*v_iter)->constPrint(); 36 } 37 38 } 39 40 void mapPrint(const map<int, char>& m) 41 { 42 /* const_iterator for const template iteration */ 43 map<int, char>::const_iterator m_iter; 44 for(m_iter = m.begin(); m_iter != m.end(); m_iter++){ 45 cout<<"index:"<<m_iter->first<<" -> "<<m_iter->second<<endl; 46 } 47 } 48 49 int main() 50 { 51 vector<Symbolic *> constraints; 52 53 constraints.push_back(new Symbolic(1, "x")); 54 constraints.push_back(new Symbolic(2, "y")); 55 constraints.push_back(new Symbolic(3, "z")); 56 57 /* make its member to be const access */ 58 vector<const Symbolic*> cs(constraints.begin(), 59 constraints.end()); 60 /* print its value and make it const to be sure that we don't modify it */ 61 vectorPrint(cs); 62 63 64 map<int, char> symb; 65 66 symb[1] = 'a'; 67 symb[2] = 'b'; 68 symb[3] = 'c'; 69 70 mapPrint(symb); 71 72 return 0; 73 }

gcc/g++使用-finstrument-functions來觀察code每個function的呼叫

2009-05-16T06:41:00.000-07:00

man gcc可以找到-finstrument-functions的一些相關說明，簡單看到下面的敘述 Generate instrumentation calls for entry and exit to functions. 所以重要的是可以將每一個function call的呼叫攔截，加上我們自己的codes，有點LD_PRELOAD的意味存在。以下介紹兩個例子，gcc和g++的寫法有點不同。 yslinnote@linux1 ~> gcc -finstrument-functions hello.c -o hello


/*hello.c*/
#include <stdio.h>
#define DUMP(func, call) \
printf("%s: func = %p, called by = %p\n", __FUNCTION__, func, call)

/* 每個函式進入時會呼叫此函式 */
void __attribute__((__no_instrument_function__))
__cyg_profile_func_enter(void *this_func, void *call_site)
{
DUMP(this_func, call_site);
}

/* 每個函式離開時會呼叫此函式 */
void __attribute__((__no_instrument_function__))
__cyg_profile_func_exit(void *this_func, void *call_site)
{
DUMP(this_func, call_site);
}

int main()
{
puts("Hello World!");
return 0;
}

yslinnote@linux1 ~> gcc -finstrument-functions hello.cc -o hello


/*hello.cc*/
#include <stdio.h>
#define DUMP(func, call) \
printf("%s: func = %p, called by = %p\n", __FUNCTION__, func, call)
#ifdef __cplusplus
extern "C"
{
void __cyg_profile_func_enter(void *this_fn, void *call_site)
    __attribute__((no_instrument_function));
void __cyg_profile_func_exit(void *this_fn, void *call_site)
    __attribute__((no_instrument_function));
}
#endif

int main()
{
puts("Hello World!");
return 0;
}
/* 每個函式進入時會呼叫此函式 */
void __cyg_profile_func_enter(void *this_func, void *call_site)
{
DUMP(this_func, call_site);
}

/* 每個函式離開時會呼叫此函式 */
void __cyg_profile_func_exit(void *this_func, void *call_site)
{
DUMP(this_func, call_site);
}

error: can't set 'no_instrument_function' attribute after definition 要是出現上面的錯誤，表示你在c++的code中多加了__attribute__((no_instrument_function))，只要在開頭宣告有加就好了。畢竟這是c的code。
