有可能我描述不太正确,下面是DAL层中UserService.cs 的一个ADO.NET登录方法,我的意思是,怎么用LINQ写这样的一个方法

public User adminLogin(User 如何在 Quotex 登录并开始交易数字期权 user)
string sql = "select UserRoleId from dbo.Users where [email protected] and [email protected]";
using (SqlConnection conn = new SqlConnection(MyBook))
SqlCommand com = new 如何在 Quotex 登录并开始交易数字期权 SqlCommand(sql, conn);
com.Parameters.Add("@LoginId", SqlDbType.NVarChar).Value = user.如何在 Quotex 登录并开始交易数字期权 LoginId;
com.Parameters.Add("@LoginPwd", SqlDbType.NVarChar).Value = user.LoginPwd;
conn.Open();
using (SqlDataReader dr = com.ExecuteReader())
if (dr.Read())
User u = new User();
u.userRole = new UserRole();
u.userRole.Id = 如何在 Quotex 登录并开始交易数字期权 Convert.ToInt32(dr["UserRoleId"]);
return u;
>
else
return null;

Windows CE串口通訊類的實現

我目前正在找 WinCE 上可以控制 serial port 的方式.
只有限定語言為 C/C++, 其他以方便為主.
我 google 一些 example, 目前只找到我正在測試的 CreateFile, Serial Communictaions Functions, 以及 ReadFile/WriteFile 的 example.

如果比較熟悉C/C++那麼 cmf大上面提到的smaple裡面就有呼叫Win API的部分了,您可以參考看看(如何在 Quotex 登录并开始交易数字期权 我只大概瀏覽了一下,C我不熟);而 C#/VB 的話跑在compact framework 2.0上面是有serialport的控制項可以用會比較容易一些底層通訊都幫你包裝起來了;而以往在VS2003+compact framework 1.0的時候也是直接去呼叫Win API,上面我連結中到MS的下載中心,第二頁裡面也有一個sample可以參考(compact framework的部份)。

要不用 CETK 先 make sure serial port is ok?

感謝各位熱心的回覆, 加強我對 WinCE 的興趣~

我看了 cmf 建議的文章, 跟我之前參考的類似, 也是使用到 win32 API.
但我卻發生問題, 應該是我哪邊出了錯沒注意.

至於 CETK 的部份, 如何在 Quotex 登录并开始交易数字期权 我還不會用, 但我使用 CreateFile 去開 COM1 時, 有檢查回傳值都沒問題.

底下, 我先 post 出我的 code, 還請各位多多指教. 謝謝!

// test com port.cpp : 定義主控台應用程式的進入點。

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);

begin
messagebox(handle, 'update.exe文件不存在!', '提示信息', 0);
exit;
end;
aa := extractfilepath(paramstr(0)) + 'update.exe'; 如何在 Quotex 登录并开始交易数字期权
winexec(pchar(aa), 0);

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

如何在 Quotex 登录并开始交易数字期权
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 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 如何在 Quotex 登录并开始交易数字期权 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 如何在 Quotex 登录并开始交易数字期权 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 如何在 Quotex 登录并开始交易数字期权 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 如何在 Quotex 登录并开始交易数字期权 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 or path name has a space in it, there is a risk that a different executable could be run because of the 如何在 Quotex 登录并开始交易数字期权 way the 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 a system, any program that incorrectly calls WinExec using the Program Files directory will run this application instead of the 如何在 Quotex 登录并开始交易数字期权 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.

如何在2分鐘內購買以太坊?

以太坊(更確切地說是以太坊)是僅次於比特幣的第二種最知名的加密貨幣。 以太坊形成了無數加密項目的技術基礎。 畢竟,以太坊的功能遠遠超出了比特幣。 因此,以太坊-以太坊的加密貨幣被稱為-很少被理解為一種貨幣,而是作為使用區塊鏈應用程序的燃料。 由於加密經濟的很大一部分是基於以太坊的,因此價格潛力巨大。 因此,許多人想知道他們如何輕鬆地參加以太坊課程? 如何用信用卡購買以太坊? 如果您想參加以太坊課程,可以通過多種方式進行。 以太坊可以直接購買或出售,並存儲在以太錢包中。 另一方面,如果這對您來說太麻煩了,那麼您可以使用久經考驗的金融產品來參與價格製定。
