求《Programming windows》电子书及FINDWINDOW，SENDMESSAGE，WINEXEC，SHELLEXECUTE这几个API函数的用法

The FindWindow function retrieves the handle to the top-level window whose class name and window name match the specified strings. This function does not search child windows. HWND FindWindow(    LPCTSTR lpClassName, // pointer to class name
    LPCTSTR lpWindowName // pointer to window name
   );
ParameterslpClassNamePoints to a null-terminated string that specifies the class name or is an atom that identifies the class-name string. If this parameter is an atom, it must be a global atom created by a previous call to the GlobalAddAtom function. The atom, a 16-bit value, must be placed in the low-order word of lpClassName; the high-order word must be zero. lpWindowNamePoints to a null-terminated string that specifies the window name (the window's title). If this parameter is NULL, all window names match.  Return ValuesIf the function succeeds, the return value is the handle to the window that has the specified class name and window name.
If the function fails, the return value is NULL. To get extended error information, call GetLastError.

The SendMessage function sends the specified message to a window or windows. The function calls the window procedure for the specified window and does not return until the window procedure has processed the message. The PostMessage function, in contrast, posts a message to a thread's message queue and returns immediately. LRESULT SendMessage(    HWND hWnd, // handle of destination window
    UINT Msg, // message to send
    WPARAM wParam, // first message parameter
    LPARAM lParam // second message parameter
   );
ParametershWndIdentifies the window whose window procedure will receive the message. If this parameter is HWND_BROADCAST, the message is sent to all top-level windows in the system, including disabled or invisible unowned windows, overlapped windows, and pop-up windows; but the message is not sent to child windows. MsgSpecifies the message to be sent. wParamSpecifies additional message-specific information. lParamSpecifies additional message-specific information.  Return ValuesThe return value specifies the result of the message processing and depends on the message sent. ResApplications that need to communicate using HWND_BROADCAST should use the RegisterWindowMessage function to obtain a unique message for inter-application communication.
If the specified window was created by the calling thread, the window procedure is called immediately as a subroutine. If the specified window was created by a different thread, Windows switches to that thread and calls the appropriate window procedure. Messages sent between threads are processed only when the receiving thread executes message retrieval code. The sending thread is blocked until the receiving thread processes the message.

The WinExec function runs the specified application. This function is provided for compatibility with earlier versions of Windows. For Win32-based applications, use the CreateProcess function. UINT WinExec(    LPCSTR lpCmdLine, // address of command line
    UINT uCmdShow // window style for new application
   );
ParameterslpCmdLinePoints to a null-terminated character string that contains the command line (filename plus optional parameters) for the application to be executed. If the name of the executable file in the lpCmdLine parameter does not contain a directory path, Windows searches for the executable file in this sequence: 1. The directory from which the application loaded.
2. The current directory.
3. The Windows system directory. The GetSystemDirectory function retrieves the path of this directory.
4. The Windows directory. The GetWindowsDirectory function retrieves the path of this directory.
5. The directories listed in the PATH environment variable.  uCmdShowSpecifies how a Windows-based application window is to be shown and is used to supply the wShowWindow member of the STARTUPINFO parameter to the CreateProcess function. For a list of the acceptable values, see the description of the nCmdShow parameter of the ShowWindow function. For a non-Windows - based application, the PIF file, if any, for the application determines the window state.  Return ValuesIf the function succeeds, the return value is greater than 31.
If the function fails, the return value is one of the following error values: Value Meaning
0 The system is out of memory or resources.
ERROR_BAD_FORMAT The .EXE file is invalid (non-Win32 .EXE or error in .EXE image).
ERROR_FILE_NOT_FOUND The specified file was not found.
ERROR_PATH_NOT_FOUND The specified path was not found.
ResWin32-based applications should use the CreateProcess function rather than this function. The WinExec function exists in Win32 to provide compatibility with earlier versions of Windows. For more information about how the WinExec function is implemented, see the Res section of the LoadModule function.
In Win32, the WinExec function returns when the started process calls the GetMessage function or a time-out limit is reached. To avoid waiting for the time out delay, call the GetMessage function as soon as possible in any process started by a call to WinExec.

1.FINDWINDOW函数功能：该函数获得一个顶层窗口的句柄，该窗口的类名和窗口名与给定的字符串相匹配。这个函数不查找子窗口。在查找时不区分大小写。函数型：HWND FindWindow（LPCTSTR IpClassName，LPCTSTR IpWindowName）; 参数： IpClassName ：指向一个指定了类名的空结束字符串，或一个标识类名字符串的成员的指针。如果该参数为一个成员，则它必须为前次调用theGlobafAddAtom函数产生的全局成员。该成员为16位，必须位于IpClassName的低 16位，高位必须为 0。 IpWindowName：指向一个指定了窗口名（窗口标题）的空结束字符串。如果该参数为空，则为所有窗口全匹配。返回值：如果函数成功，返回值为具有指定类名和窗口名的窗口句柄；如果函数失败，返回值为NULL。若想获得更多错误信息，请调用GetLastError函数。备注：Windows CE：若类名是一个成员，它必须是从 RegisterClass返回的成员。速查：Windows NT：3.1以上版本；Windows：95以上版本；Windows CE：1.0以上版本；头文件：Winuser.h；库文件：user32.lib; Unicode：在 Windows NT上实现为 Unicode和 ANSI两种版本。2.SENDMESSAGE函数功能：该函数将指定的消息发送到一个或多个窗口。此函数为指定的窗口调用窗口程序，直到窗口程序处理完消息再返回。而函数PostMessage不同，将一个消息寄送到一个线程的消息队列后立即返回。函数原型：LRESULT SendMessage（HWND hWnd，UINT Msg，WPARAM wParam，LPARAM IParam）；参数： hWnd：其窗口程序将接收消息的窗口的句柄。如果此参数为HWND_BROADCAST，则消息将被发送到系统中所有顶层窗口，包括无效或不可见的非自身拥有的窗口、被覆盖的窗口和弹出式窗口，但消息不被发送到子窗口。 Msg：指定被发送的消息。 wParam：指定附加的消息指定信息。 IParam：指定附加的消息指定信息。返回值：返回值指定消息处理的结果，依赖于所发送的消息。备注：需要用HWND_BROADCAST通信的应用程序应当使用函数RegisterWindowMessage来为应用程序间的通信取得一个唯一的消息。如果指定的窗口是由调用线程创建的，则窗口程序立即作为子程序调用。如果指定的窗口是由不同线程创建的，则系统切换到该线程并调用恰当的窗口程序。线程间的消息只有在线程执行消息检索代码时才被处理。发送线程被阻塞直到接收线程处理完消息为止。 Windows CE：Windows CE不支持Windows桌面平台支持的所有消息。使用SendMesssge之前，要检查发送的消息是否被支持。速查：Windows NT：3.1及以上版本：Windows：95及以上版本；Windows CE：1.0及以上版本；头文件：winuser.h；输入库：user32.lib；Unicode：在Windows NT环境下以Unicode和ANSI方式实现。

The ShellExecute function opens or prints a specified file. The file can be an executable file or a document file. See ShellExecuteEx also. HINSTANCE ShellExecute(    HWND hwnd, // handle to parent window
    LPCTSTR lpOperation, // pointer to string that specifies operation to perform
    LPCTSTR lpFile, // pointer to filename or folder name string
    LPCTSTR lpParameters, // pointer to string that specifies executable-file parameters
    LPCTSTR lpDirectory, // pointer to string that specifies default directory
    INT nShowCmd // whether file is shown when opened
   );
ParametershwndSpecifies a parent window. This window receives any message boxes that an application produces. For example, an application may report an error by producing a message box.lpOperationPointer to a null-terminated string that specifies the operation to perform. The following operation strings are valid:String Meaning
"open" The function opens the file specified by lpFile. The file can be an executable file or a document file. The file can be a folder to open.
"print" The function prints the file specified by lpFile. The file should be a document file. If the file is an executable file, the function opens the file, as if "open" had been specified.
"explore" The function explores the folder specified by lpFile.
The lpOperation parameter can be NULL. In that case, the function opens the file specified by lpFile. lpFilePointer to a null-terminated string that specifies the file to open or print or the folder to open or explore. The function can open an executable file or a document file. The function can print a document file. lpParametersIf lpFile specifies an executable file, lpParameters is a pointer to a null-terminated string that specifies parameters to be passed to the application.
If lpFile specifies a document file, lpParameters should be NULL. lpDirectoryPointer to a null-terminated string that specifies the default directory. nShowCmdIf lpFile specifies an executable file, nShowCmd specifies how the application is to be shown when it is opened.  This parameter can be one of the following values: Value Meaning
SW_HIDE Hides the window and activates another window.
SW_MAXIMIZE Maximizes the specified window.
SW_MINIMIZE Minimizes the specified window and activates the next top-level window in the Z order.
SW_RESTORE Activates and displays the window. If the window is minimized or maximized, Windows restores it to its original size and position. An application should specify this flag when restoring a minimized window.
SW_SHOW Activates the window and displays it in its current size and position.
SW_SHOWDEFAULT Sets the show state based on the SW_ flag specified in the STARTUPINFO structure passed to the CreateProcess function by the program that started the application. An application should call ShowWindow with this flag to set the initial show state of its main window.
SW_SHOWMAXIMIZED Activates the window and displays it as a maximized window.
SW_SHOWMINIMIZED Activates the window and displays it as a minimized window.
SW_SHOWMINNOACTIVE Displays the window as a minimized window. The active window remains active.
SW_SHOWNA Displays the window in its current state. The active window remains active.
SW_SHOWNOACTIVATE Displays a window in its most recent size and position. The active window remains active.
SW_SHOWNORMAL Activates and displays a window. If the window is minimized or maximized, Windows restores it to its original size and position. An application should specify this flag when displaying the window for the first time.
If lpFile specifies a document file, nShowCmd should be zero.  Return ValuesIf the function succeeds, the return value is the instance handle of the application that was run, or the handle of a dynamic data exchange (DDE) server application.
If the function fails, the return value is an error value that is less than or equal to 32. The following table lists these error values:Value Meaning
0 The operating system is out of memory or resources.
ERROR_FILE_NOT_FOUND The specified file was not found.
ERROR_PATH_NOT_FOUND The specified path was not found.
ERROR_BAD_FORMAT The .EXE file is invalid (non-Win32 .EXE or error in .EXE image).
SE_ERR_ACCESSDENIED The operating system denied access to the specified file.
SE_ERR_ASSOCINCOMPLETE The filename association is incomplete or invalid.
SE_ERR_DDEBUSY The DDE transaction could not be completed because other DDE transactions were being processed.
SE_ERR_DDEFAIL The DDE transaction failed.
SE_ERR_DDETIMEOUT The DDE transaction could not be completed because the request timed out.
SE_ERR_DLLNOTFOUND The specified dynamic-link library was not found.
SE_ERR_FNF The specified file was not found.
SE_ERR_NOASSOC There is no application associated with the given filename extension.
SE_ERR_OOM There was not enough memory to complete the operation.
SE_ERR_PNF The specified path was not found.
SE_ERR_SHARE A sharing violation occurred.
ResThe file specified by the lpFile parameter can be a document file or an executable file. If the file is a document file, the ShellExecute function opens or prints it, depending on the value of the lpOperation parameter. If the file is an executable file, the ShellExecute function opens it, even if
lpOperation specifies printing.
You can use ShellExecute to open or explore a shell folder. To open a folder, use either of the following calls:ShellExecute(handle, NULL, path_to_folder, NULL, NULL, SW_SHOWNORMAL);or
  ShellExecute(handle, "open", path_to_folder, NULL, NULL, SW_SHOWNORMAL);
  To explore a folder, use the following call:ShellExecute(handle, "explore", path_to_folder, NULL, NULL, SW_SHOWNORMAL);
  If lpOperation is NULL, the function opens the file specified by lpFile. If lpOperation is "open" or "explore", the function will force an open window or explorer.

[Now Supported on Windows NT]The ShellExecuteEx function performs an action on a file. The file can be an executable file or a document.WINSHELLAPI BOOL WINAPI ShellExecuteEx(    LPSHELLEXECUTEINFO lpExecInfo // pointer to SHELLEXECUTEINFO structure
   );
ParameterslpExecInfoPointer to a SHELLEXECUTEINFO structure that contains and receives information about the application to start.  Return ValuesIf the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error information, call GetLastError. ResIf the function succeeds, it sets the hInstApp member of the SHELLEXECUTEINFO structure to the instance handle of the application that the function started. If the function fails, hInstApp is one of the SE_ERR_ error values indicating the cause of the failure. (An instance handle will always be greater than 32, and an error value less than 32.) Note that the SE_ERR_ error values are for compatibility with the ShellExecute function; use the GetLastError function to retrieve error information. Last error values returned by GetLastError correspond to the SE_ERR_ values and may be one of the following:Value Meaning
ERROR_FILE_NOT_FOUND The specified file was not found.
ERROR_PATH_NOT_FOUND The specified path was not found.
ERROR_DDE_FAIL The DDE transaction failed.
ERROR_NO_ASSOCIATION There is no application associated with the given filename extension.
ERROR_ACCESS_DENIED
ERROR_DLL_NOT_FOUND
ERROR_CANCELLED The function prompted the user for the location of the application, but the user cancelled the request.
ERROR_NOT_ENOUGH_MEMORY
ERROR_SHARING_VIOLATION A sharing violation occurred.

procedure TForm1.Button1Click(Sender: TObject);
var
   H : Thandle ;
begin
   Winexec('C:\test.exe',SW_show);//调用一个外部程序
   H := findwindow(nil,'Form1');//找到本窗体句并
   if h <> 0 then
   begin
   showmessage('ok') ;
   Sendmessage(h, WM_Close,0,0);//给本窗体发送关闭消息
    end ;end;
下面转铁一些消息定义：消息，就是指Wi n d o w s发出的一个通知，告诉应用程序某个事情发生了。例如，单击鼠标、改变
窗口尺寸、按下键盘上的一个键都会使Wi n d o w s发送一个消息给应用程序。
消息本身是作为一个记录传递给应用程序的，这个记录中包含了消息的类型以及其他信息。例如，
对于单击鼠标所产生的消息来说，这个记录中包含了单击鼠标时的坐标。这个记录类型叫做T M s g，它
在Wi n d o w s单元中是这样声明的：
t y p e
TMsg = packed record
hwnd: HWND; / /窗口句柄
message: UINT; / /消息常量标识符
wParam: WPA R A M ; // 32位消息的特定附加信息
lParam: LPA R A M ; // 32位消息的特定附加信息
time: DWORD; / /消息创建时的时间
pt: TPoint; / /消息创建时的鼠标位置
e n d ;
消息中有什么？
是否觉得一个消息记录中的信息像希腊语一样？如果是这样，那么看一看下面的解释：
hwnd 32位的窗口句柄。窗口可以是任何类型的屏幕对象，因为Win32能够维护大多数可
视对象的句柄(窗口、对话框、按钮、编辑框等)。
message 用于区别其他消息的常量值，这些常量可以是Windows单元中预定义的常量，也
可以是自定义的常量。
wParam 通常是一个与消息有关的常量值，也可能是窗口或控件的句柄。
lParam 通常是一个指向内存中数据的指针。由于W P a r a m、l P a r a m和P o i n t e r都是3 2位的，
因此，它们之间可以相互转换。
