调用api试试WinExec The WinExec function runs the specified application. Note  This function is provided only for compatibility with 16-bit Windows. Win32-based applications should use the CreateProcess function. UINT WinExec(   LPCSTR lpCmdLine,  // command line   UINT uCmdShow      // window style ); Parameters lpCmdLine [in] Pointer to a null-terminated character string that contains the command line (file name 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, the system searches for the executable file in this sequence: The directory from which the application loaded. The current directory. The Windows system directory. The GetSystemDirectory function retrieves the path of this directory. The Windows directory. The GetWindowsDirectory function retrieves the path of this directory. The directories listed in the PATH environment variable. uCmdShow [in] Specifies 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 Values If 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. Remarks 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. Requirements   Windows NT/2000: Requires Windows NT 3.1 or later.   Windows 95/98: Requires Windows 95 or later.   Header: Declared in Winbase.h; include Windows.h.   Library: Use Kernel32.lib.

这种方法太老了吧,直接用hhctrl.ocx上的函数吧，下面的例子只实现了直接转跳到标题 ,你如果要实现更多的功能，自己查msdn了 HTMLHelp API Reference The HtmlHelp API currently resides in the file HTMLHELP.DLL, however this is very likely to be moved to a different DLL before HTML Help ships. If you are not using GetProcAddress to get a pointer to the HtmlHelp function, then you must plan on changing the library you link to. The functionality provided by the HtmlHelp API resides in the file HHCTRL.OCX. Because this functionality requires loading various other DLLs such as ole32.dll, the API itself resides in a DLL that requires no additional DLLs to be loaded. Only when the API is actually called will ole32 and other DLLs be loaded. The HtmlHelp API is modeled after the WinHelp API function to make it easy to convert existing programs to use HTML Help instead of WinHelp to display their help. By the time HTML Help ships, there will also be an IHHWindow interface that can be used in place of the HtmlHelp API. This can be used by programs that already load OLE32.DLL or by programs like Visual Basic. In its simplest form, the HtmlHelp API creates a child window which in turn hosts SHDOCVW and displays the HTML file you specify. The window is a child of whatever parent window you specify, and will automatically stay on top of that parent window, and close when the parent window is closed. You can also take complete control of the window-creation process by defining the window styles, coordinates, caption, and display state. This means you can embed SHDOCVW even in a non-OLE activated program. SYNTAX HWND HtmlHelp(HWND hwndCaller, LPCSTR pszFile, UINT uCommand, DWORD dwData); hwndCaller Specifies the handle of the window calling the HtmlHelp API. If the HtmlHelp API call results in messages being sent from the HTML Help window, they will be sent to this window handle. pszFile Specifies an HTML file, a URL, a compiled HTML file, or a window definition (preceeded with a ‘>’ character). If the command being used does not require a file or URL, this value may be NULL. uCommand Specifies the action to perform. See the Comments section for details. dwData Specifies any data that may be required based on the value of the uCommand parameter. Comments 太长了，自己查msdn帮助吧 在delphi中的函数定义 Function HtmlHelpA(hwnd:integer;lpHelpFile:string;wCommand:integer;dwData:string) :integer;stdcall;External 'hhctrl.ocx'; wCommand要自己查msdn中需要的参数，然后换成0、1这些 使用参数 Command Description pszFile dwData HH_DISPLAY_TOPIC Displays an HTML file. If a window type is not specified, a default window type is used. If the window type or default window type is already being displayed, the HTML file will replace what is currently being displayed. File, URL, or compiled HTML file. If the greater then character (&gt

is used, it must be followed by the name of the window type to display the topic in. May be zero or a pointer to a File, URL, or compiled HTML file. This parameter may be a pointer to a filename within a compiled HTML file if the pszFile parameter points to that compiled HTML file. HtmlHelpA(Handle,'c:/htmlhelp2/rshelp.chm',0,'欢迎.htm'

我同意bugs的 SHELLEXECUTEINFO Contains information used by ShellExecuteEx. typedef struct _SHELLEXECUTEINFO{     DWORD cbSize;     ULONG fMask;     HWND hwnd;     LPCTSTR lpVerb;     LPCTSTR lpFile;     LPCTSTR lpParameters;     LPCTSTR lpDirectory;     int nShow;     HINSTANCE hInstApp;       // Optional members     LPVOID lpIDList;     LPCSTR lpClass;     HKEY hkeyClass;     DWORD dwHotKey; union { HANDLE hIcon; HANDLE hMonitor; };     HANDLE hProcess; } SHELLEXECUTEINFO, *LPSHELLEXECUTEINFO;   Members cbSize Size of the structure, in bytes. fMask Array of flags that indicate the content and validity of the other structure members. This can be a combination of the following values. SEE_MASK_CLASSKEY  Use the class key given by the hkeyClass member.   SEE_MASK_CLASSNAME  Use the class name given by the lpClass member.   SEE_MASK_CONNECTNETDRV  Validate the share and connect to a drive letter. The lpFile member is a Universal Naming Convention (UNC) path of a file on a network.   SEE_MASK_DOENVSUBST  Expand any environment variables specified in the string given by the lpDirectory or lpFile member.   SEE_MASK_FLAG_DDEWAIT  Wait for the DDE conversation to terminate before returning (if the ShellExecuteEx function causes a DDE conversation to start). For circumstances in which this flag is necessary, see the Remarks section. SEE_MASK_FLAG_NO_UI  Do not display an error message box if an error occurs.   SEE_MASK_HMONITOR Use this flag when specifying a monitor on multimonitor systems. The monitor is specified in the hMonitor member. This flag cannot be combined with SEE_MASK_ICON. SEE_MASK_HOTKEY  Use the hot key given by the dwHotKey member. SEE_MASK_ICON  Use the icon given by the hIcon member. This flag cannot be combined with SEE_MASK_HMONITOR. SEE_MASK_IDLIST  Use the item identifier list given by the lpIDList member. The lpIDList member must point to an ITEMIDLIST structure. SEE_MASK_INVOKEIDLIST  Use the IContextMenu interface of the selected item's context menu handler. Use either lpFile to identify the item by its file system path or lpIDList to identify the item by its PIDL. This flag allows applications to use ShellExecuteEx to invoke verbs from context menu extensions instead of the static verbs listed in the registry. SEE_MASK_NOCLOSEPROCESS  Use to indicate that the hProcess member receives the process handle. This handle is typically used to allow an application to find out when a process created with ShellExecuteEx terminates. In some cases, such as when execution is satisfied through a DDE conversation, no handle will be returned. The calling application is responsible for closing the handle when it is no longer needed. SEE_MASK_NO_CONSOLE Use to create a console for the new process instead of having it inherit the parent's console. It is equivalent to using a CREATE_NEW_CONSOLE flag with CreateProcess. SEE_MASK_UNICODE Use this flag to indicate a Unicode application. hwnd Window handle to any message boxes that the system might produce while executing this function. lpVerb String, referred to as a verb, that specifies the action to be performed. The set of available verbs depends on the particular file or folder. Generally, the actions available from an object's context menu are available verbs. For more specific information about verbs, see Object Verbs. For further discussion of context menus, see Extending Context Menus. The following verbs are commonly used. edit  Launches an editor and opens the document for editing. If lpFile is not a document file, the function will fail. explore Explores the folder specified by lpFile.   find Initiates a search starting from the specified directory. open  Opens the file specified by the lpFile parameter. The file can be an executable file, a document file, or a folder. print  Prints the document file specified by lpFile. If lpFile is not a document file, the function will fail. properties  Displays the file or folder's properties. If you set this parameter to NULL: For systems prior to Microsoft&reg; Windows&reg; 2000, the default verb is used if it is valid and available in the registry. If not, the "open" verb is used. For Windows 2000 and later systems, the default verb is used if available. If not, the "open" verb is used. If neither verb is available, the system uses the first verb listed in the registry. lpFile Address of a null-terminated string that specifies the name of the file or object on which ShellExecuteEx will perform the action specified by the lpVerb parameter. The system registry verbs that are supported by the ShellExecuteEx function include "open" for executable files and document files and "print" for document files for which a print handler has been registered. Other applications might have added shell verbs through the system registry, such as "play" for AVI and WAV files. To specify a shell namespace object, pass the fully qualified parse name and set the SEE_MASK_INVOKEIDLIST flag in the fMask parameter. Note If the path is not included with the name, the current directory is assumed. lpParameters Address of a null-terminated string that contains the application parameters. The parameters must be separated by spaces. To include double quotation marks, enclose each mark in a pair of quotation marks, as in the following example. sei.lpParameters = "An example: /"/"/"quoted text/"/"/""; In this case, the application receives three parameters: An, example:, and "quoted text". If the lpFile member specifies a document file, this member should be NULL. lpDirectory Address of a null-terminated string that specifies the name of the working directory. If this member is not specified, the current directory is used as the working directory. nShow Flags that specify how an application is to be shown when it is opened. It can be one of the SW_ values listed for the ShellExecute function. If lpFile specifies a document file, the flag is simply passed to the associated application. It is up to the application to decide how to handle it. hInstApp If the function succeeds, it sets this member to a value greater than 32. If the function fails, it is set to an SE_ERR_XXX error value that indicates the cause of the failure. Although hInstApp is declared as an HINSTANCE for compatibility with 16-bit Windows applications, it is not a true HINSTANCE. It can be cast only to an integer and compared to either 32 or the following SE_ERR_XXX error codes. SE_ERR_FNF  File not found. SE_ERR_PNF  Path not found. SE_ERR_ACCESSDENIED  Access denied. SE_ERR_OOM  Out of memory. SE_ERR_DLLNOTFOUND  Dynamic-link library not found. SE_ERR_SHARE  Cannot share an open file. SE_ERR_ASSOCINCOMPLETE  File association information not complete. SE_ERR_DDETIMEOUT  DDE operation timed out. SE_ERR_DDEFAIL  DDE operation failed. SE_ERR_DDEBUSY  DDE operation is busy. SE_ERR_NOASSOC  File association not available. lpIDList Address of an ITEMIDLIST structure to contain an item identifier list uniquely identifying the file to execute. This member is ignored if the fMask member does not include SEE_MASK_IDLIST. lpClass Address of a null-terminated string that specifies the name of a file class or a globally unique identifier (GUID). This member is ignored if fMask does not include SEE_MASK_CLASSNAME. hkeyClass Handle to the registry key for the file class. This member is ignored if fMask does not include SEE_MASK_CLASSKEY. dwHotKey Hot key to associate with the application. The low-order word is the virtual key code, and the high-order word is a modifier flag (HOTKEYF_). For a list of modifier flags, see the description of the WM_SETHOTKEY message. This member is ignored if fMask does not include SEE_MASK_HOTKEY. hIcon Handle to the icon for the file class. This member is ignored if fMask does not include SEE_MASK_ICON. hMonitor Handle to the monitor upon which the document is to be displayed. This member is ignored if fMask does not include SEE_MASK_HMONITOR. hProcess Handle to the newly started application. This member is set on return and is always NULL unless fMask is set to SEE_MASK_NOCLOSEPROCESS. Even if fMask is set to SEE_MASK_NOCLOSEPROCESS, hProcess will be NULL if no process was launched. For example, if a document to be launched is a URL and an instance of Microsoft&reg; Internet Explorer is already running, it will display the document. No new process is launched, and hProcess will be NULL. Remarks The SEE_MASK_DDEWAIT flag must be specified if the thread calling ShellExecuteEx does not have a message loop or if the thread or process will terminate soon after ShellExecuteEx returns. Under such conditions, the calling thread will not be available to complete the DDE conversation, so it is important that ShellExecuteEx complete the conversation before returning control to the caller. Failure to complete the conversation can result in an unsuccessful launch of the document. If the calling thread has a message loop and will exist for some time after the call to ShellExecuteEx returns, the SEE_MASK_DDEWAIT flag is optional. If the flag is omitted, the calling thread's message pump will be used to complete the DDE conversation. The calling application regains control sooner, since the DDE conversation can be completed in the background. Requirements   Windows NT/2000: Requires Windows NT 3.51 or later.   Windows 95/98: Requires Windows 95 or later.   Header: Declared in Shellapi.h. ------------------------------------------------------------以上是结构 ShellExecuteEx Performs an action on a file. BOOL ShellExecuteEx(     LPSHELLEXECUTEINFO lpExecInfo ); Parameters lpExecInfo Address of a SHELLEXECUTEINFO structure that contains and receives information about the application being executed. Return Values Returns TRUE if successful, or FALSE otherwise. Call GetLastError for error information. Remarks With multiple monitors, if you specify an hwnd and set the lpVerb member of lpExecInfo to "Properties" , any windows created by ShellExecuteEx may not appear in the correct position. If the function succeeds, it sets the hInstApp member of the SHELLEXECUTEINFO structure to a value greater than 32. If the function fails, hInstApp is set to the SE_ERR_XXX error value that best indicates the cause of the failure. Although hInstApp is declared as an HINSTANCE for compatibility with 16-bit Microsoft Windows applications, it is not a true HINSTANCE. It can only be cast to an integer and compared to either 32 or the SE_ERR_XXX error codes. Note: the SE_ERR_XXX error values are provided for compatibility with ShellExecute. To retrieve more accurate error information, use GetLastError. It may return one of the following values: 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 file name extension. ERROR_ACCESS_DENIED  Access to the specified file is denied. ERROR_DLL_NOT_FOUND  One of the library files necessary to run the application can't be found. ERROR_CANCELLED  The function prompted the user for additional information, but the user canceled the request. ERROR_NOT_ENOUGH_MEMORY  There is not enough memory to perform the specified action. ERROR_SHARING_VIOLATION  A sharing violation occurred. See Also IShellExecuteHook Requirements   Version 4.00 and later of Shell32.dll   Windows NT/2000: Requires Windows NT 4.0 or later.   Windows 95/98: Requires Windows 95 or later.   Header: Declared in shellapi.h.   Import Library: shell32.lib ---------------------------------------------以上是api
