1. Right-click on the VC to click on a class or macro, you can look at his definition, but how to return to the initial place?
Install Visual Assist, And Use Alt Left Arrow
Press the back of the menu (<- turn 45 degrees) button
It seems that I opened a document and turned off it.
2, how to get the system menu, and pop up the system menu?
Void ctestsysmenudlg :: onok ()
{
// Click The Ok Button to Show System Menu (Masterz)
Point curpos;
GetCursorpos (& Curpos);
SetForegroundWindow ();
CMenu * pmenu = getSystemMenu (false);
INT nSelection = pmenu-> TRACKPOPUPMENU (TPM_LEFTBUTTON | TPM_LEFTALIGN |
TPM_BOTTOMALIGN | TPM_NONOTIFY | TPM_RETURNCMD, CURPOS.X, CURPOS.Y, THIS
DWORD DWPOS = Curpos.x (Curpos.Y << 16) & 0xffff0000);
SendMessage (WM_SYSCOMMAND, NSELECTION, DWPOS);
CSTRING MSG;
Msg.format ("x:% d, y:% d; cursor.x =% d, cursor.y =% d", loword (dwpos), Hiword (dwpos), curpos.x, curpos.y);
OutputDebugstring (MSG);
}
3, how to control the brightness of the three lamps above the keyboard (Num Lock, Caps Lock Srcoll Lock)
#include
Void SetNumlock (Bool BState)
{
Byte KeyState [256];
GetKeyboardState (LPBYTE) & keystate;
IF ((BState &&! (KeyState [vk_numlock] & 1) ||
(! BState && (KeyState [vk_numlock] & 1)))))))
{
// Simulate a Key Press
Keybd_Event (vk_numlock,
0x45,
KeyEventf_extendedKey | 0,
0);
// simulate a key release
Keybd_Event (vk_numlock,
0x45,
KeyEventf_extendedKey | KeyEventf_Keyup,
0);
}
}
void main ()
{
SetNUMLOCK (TRUE);
}
4. How to change it to English after the Chinese is selected in the appWizard of VC?
Open the resource file with a file editor, find "Language", find it after finding:
// Chinese (p.r.c) resources
#if! defined (AFX_RESOURCE_DLL) || Defined (AFX_TARG_CHS)
#ifdef _win32
Language lang_chinese, SUBLANG_CHINESE_SIMPLIFIED
#pragma code_page (936)
#ENDIF / / / WIN32
This code indicates that the currently used code page is 936. The language represented is Simplified Chinese, and the following code is replaced with the following code: // English (u.s) Resources
#if! defined (AFX_RESOURCE_DLL) || Defined (AFX_TARG_ENU)
#ifdef _win32
Language lang_english, sublang_english_us
#pragma code_page (1252)
#ENDIF / / / WIN32
5. How to effectively determine if the mouse point is in the rectangular area of the control
DWORD DW = GetMessagePos ();
Cpoint PT (Loword (DW), HiWord (DW)); // Mouse screen coordinate
CRECT R;
Getdlgitem (idc_edit1) -> getClientRect (& R);
Getdlgitem (IDC_EDIT1) -> ClientToscreen (& R);
IF (r.ptinRect (PT))
AfxMessageBox ("in the control");
6, handle the right click of the control, no
Bool ccDialogdlg :: PretranslateMessage (MSG * PMSG)
{
IF (WM_Mousemove == PMSG-> Message)
IF (PMSG-> hwnd == getdlgitem (idc_button1) -> getsafehwnd ())
{
Uint nflag = pmsg-> wparam; // state, such as Ctrl is not pressed
INT XPOS = loword (pmsg-> lparam); // Horizontal Position of Cursor
INT YPOS = HiWord (PMSG-> lparam); // Vertical Position of Cursor
}
Return CDIALOG :: PretranslateMessage (PMSG);
}
