我有使用CreateProcess 可以起動別的程式 可是無法傳參數呢 如果 再指定名稱,後面再加上參數時,就會無法啟動程式呢 目前試過 只有 winexec傳參數且執行外部程式 可以用呢 請問有人知道要怎樣用嗎 CreateProcess 傳參數且執行外部程式

引言: //說明 The CreateProcess function creates a new process and its primary thread. The new process executes the specified executable file. BOOL CreateProcess( LPCTSTR lpApplicationName, // pointer to name of executable module LPTSTR lpCommandLine, // pointer to command line string LPSECURITY_ATTRIBUTES lpProcessAttributes, // pointer to process security attributes LPSECURITY_ATTRIBUTES lpThreadAttributes, // pointer to thread security attributes BOOL bInheritHandles, // handle inheritance flag DWORD dwCreationFlags, // creation flags LPVOID lpEnvironment, // pointer to new environment block LPCTSTR lpCurrentDirectory, // pointer to current directory name LPSTARTUPINFO lpStartupInfo, // pointer to STARTUPINFO LPPROCESS_INFORMATION lpProcessInformation // pointer to PROCESS_INFORMATION ); Parameters lpApplicationName Pointer to a null-terminated string that specifies the module to execute. The string can specify the full path and filename of the module to execute. The string can specify a partial name. In that case, the function uses the current drive and current directory to complete the specification. The lpApplicationName parameter can be NULL. In that case, the module name must be the first white space-delimited token in the lpCommandLine string. The specified module can be a Win32-based application. It can be some other type of module (for example, MS-DOS or OS/2) if the appropriate subsystem is available on the local computer. Windows NT: If the executable module is a 16-bit application, lpApplicationName should be NULL, and the string pointed to by lpCommandLine should specify the executable module. A 16-bit application is one that executes as a VDM or WOW process. lpCommandLine Pointer to a null-terminated string that specifies the command line to execute. The lpCommandLine parameter can be NULL. In that case, the function uses the string pointed to by lpApplicationName as the command line. If both lpApplicationName and lpCommandLine are non-NULL, *lpApplicationName specifies the module to execute, and *lpCommandLine specifies the command line. The new process can use GetCommandLine to retrieve the entire command line. C runtime processes can use the argc and argv arguments. If lpApplicationName is NULL, the first white space-delimited token of the command line specifies the module name. If the filename does not contain an extension, .EXE is assumed. If the filename ends in a period (.) with no extension, or the filename contains a path, .EXE is not appended. If the filename does not contain a directory path, Windows searches for the executable file in the following sequence: 1. The directory from which the application loaded. 2. The current directory for the parent process. 3. Windows 95: The Windows system directory. Use the GetSystemDirectory function to get the path of this directory. Windows NT: The 32-bit Windows system directory. Use the GetSystemDirectory function to get the path of this directory. The name of this directory is SYSTEM32. 4. Windows NT: The 16-bit Windows system directory. There is no Win32 function that obtains the path of this directory, but it is searched. The name of this directory is SYSTEM. 5. The Windows directory. Use the GetWindowsDirectory function to get the path of this directory. 6. The directories that are listed in the PATH environment variable. If the process to be created is an MS-DOS - based or Windows-based application, lpCommandLine should be a full command line in which the first element is the application name. Because this also works well for Win32-based applications, it is the most robust way to set lpCommandLine. lpProcessAttributes Pointer to a SECURITY_ATTRIBUTES structure that determines whether the returned handle can be inherited by child processes. If lpProcessAttributes is NULL, the handle cannot be inherited. Windows NT: The lpSecurityDescriptor member of the structure specifies a security descriptor for the new process. If lpProcessAttributes is NULL, the process gets a default security descriptor. Windows 95: The lpSecurityDescriptor member of the structure is ignored. // 範例 procedure TForm1.Button1Click(Sender: TObject); var B: Boolean; SI: TStartUpInfo; // holds startup information PI: TProcessInformation; // holds process information VerInfo: TOSVersionInfo; begin // get windows version VerInfo.dwOSVersionInfoSize := SizeOf(TOSVersionInfo); GetVersionEx(VerInfo); {initialize the startup information} FillChar(SI, SizeOf(TStartupInfo), 0); with SI do begin cb := SizeOf(TStartupInfo); dwFlags := STARTF_USESHOWWINDOW; wShowWindow := SW_SHOW; end; // 請注意 CreateProcess 會因為 windows 版本寫法會有所不同 目前是 win2000 if VerInfo.dwPlatformId = VER_PLATFORM_WIN32_WINDOWS then B := CreateProcess(Nil,PCAHR('C:\WINDOWS\SYSTEM\CALC.EXE'),Nil, Nil, False, NORMAL_PRIORITY_CLASS, Nil, Nil, SI, PI) else // Win2000 會執行這一行 B := CreateProcess(PCHAR('C:\WINNT\SYSTEM32\CALC.EXE'),Nil,Nil, Nil, False, NORMAL_PRIORITY_CLASS, Nil, Nil, SI, PI); // WaitForSingleObject(PI.hProcess, 0); // WaitForInputIdle(PI.hProcess, INFINATE); // 會等候輸入完畢 ....... // 請參閱 Delphi Help (Delphi 6.0 , 7.0) ( ?

to 列為大大 小弟剛試ㄌ一下 如果我只是呼叫一般的應用程式如小算盤，記事本等 不論是R大大獲懷舊大大ㄉ程式 都沒有任何問題 但是一但呼叫一ㄍ安裝程式就會出現上述ㄉ現象 請問列為先進 這是什麼問題所造成ㄋ 備註:我所呼叫ㄉ安裝程式是由DELPHI4所附ㄉINSTALLSHELL包裝ㄉ 小弟試著使用如ShellExecute的方法如下: ShellExecute(Application.Handle, PChar('Open'), PChar(ExtractFilePath(Application.EXEName) 'salsystem\setup.exe'), PChar(''), nil, SW_NORMAL); 安裝程式可以呼叫出來執行到一半卻會出現如下的錯誤訊息: Setup is unable to decompress and copy all of the programfiles needed to proceed with the installation.
