如何在delphi调用一exe程序

var
StartupInfo: TStartupInfo ;
ProcessInfo : TProcessInformation ;
begin
FillChar (StartupInfo , Sizeof(StartupInfo), #0 ) ;
StartupInfo.cb := Sizeof(StartupInfo);
StartupInfo.dwFlags := STARTF_USESHOWWINDOW;

CreateProcess(nil ,'update',nil ,nil,false,CREATE_NEW_CONSOLE or NORMAL_PRIORITY_CLASS,nil,nil,StartupInfo,ProcessInfo);
end;

if not fileexists(extractfilepath(paramstr(0)) + 'update.exe') then
begin
messagebox(handle, '如何在 Quotex 登录并开始交易数字期权 update.exe文件不存在!', '提示信息', 0);
exit;
end;
aa := extractfilepath(paramstr(0)) + 'update.exe';
winexec(pchar(aa), 0);

用WinExec("\"C:\Program Files\MyApp.exe\" -L -S", . )


The WinExec function runs the specified application.

Note This function is provided only for compatibility with 16-bit Windows. Applications should use the CreateProcess function.

UINT WinExec(
LPCSTR lpCmdLine, // command line
UINT uCmdShow // window style
);
Parameters 如何在 Quotex 登录并开始交易数字期权
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 如何在 Quotex 登录并开始交易数字期权 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 如何在 Quotex 登录并开始交易数字期权 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 如何在 Quotex 登录并开始交易数字期权 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.
ERROR_FILE_NOT_FOUND The specified file was not found.
ERROR_PATH_NOT_FOUND The specified path was not found.


Remarks
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.

Security Remarks
The executable name is treated as the first white space-delimited string in lpCmdLine. If the executable 如何在 Quotex 登录并开始交易数字期权 or path name has a space in it, there is a risk that a different executable 如何在 Quotex 登录并开始交易数字期权 could be run because of the way the 如何在 Quotex 登录并开始交易数字期权 function parses spaces. The following example is dangerous because the function will attempt to run "Program.exe", if it exists, instead of "MyApp.exe".

WinExec("C:\Program Files\MyApp", . )
If a malicious user were to create an application called "Program.exe" on 如何在 Quotex 登录并开始交易数字期权 如何在 Quotex 登录并开始交易数字期权 a system, any program that incorrectly calls WinExec using the Program Files directory will run this application instead of the intended application.

To avoid this problem, use CreateProcess rather than WinExec. However, if you must use WinExec for legacy reasons, make sure the application name is enclosed in quotation marks as shown in the example below.

WinExec("\"C:\Program Files\MyApp.exe\" -L -S", . )
Requirements
Windows NT/2000/XP: Included in Windows NT 3.1 and later.
Windows 95/98/Me: Included in Windows 95 and later.
Header: Declared in Winbase.h; include Windows.h.
Library: Use Kernel32.lib.

1) ADOCE是ActiveX元件, 所以要確定有加到WINCE Kernel中
2) 記得ActiveSync 4.2版之前的版本才有支援CDB資料庫的轉換
3) CCeDB是WINCE內建的階層式資料庫, 不是關聯式資料庫

CDB資料庫就是Pocket Access, 可以利用ADOCE元件進行操作, 請參考:範例: ADOVC1 簡單 ADO / 如何在 Quotex 登录并开始交易数字期权 VC ++ 應用程式(http://support.microsoft.com/default.aspx/kb/220152)

ADOCE是只要在winCE環境下都能夠操作嗎,還是必須安裝其它程式,或是在build wince kernal時必須進行什麼設定?
找了一些說明,但仍對使用ADOCE所須的設定及要求的環境不太了解
