How to Convert Datetime to OracleTimeStamp

I have a problem where I cannot run a function from a database using ODP.NET because I cannot convert one of my arguments to a timestamp. I'm using : ODAC121010Xcopy_32bit ODP.NET4 I've checked quite a few questions and I've also tried converting the datetime object into a string format to pass it. I've spent hours on this and honestly can't figure out if I'm missing

如何将日期时间转换为OracleTimeStamp

我有一个问题,我无法使用ODP.NET从数据库运行函数,因为我无法将其中一个参数转换为时间戳。 我正在使用:ODAC121010Xcopy_32bit ODP.NET4 我检查了很多问题,我也尝试将日期时间对象转换为字符串格式来传递它。 我已经花了几个小时了,老实说不知道我是否错过了一些东西。 这似乎是这样的常识,我无法弄清楚为什么这不起作用,任何帮助都将不胜感激。 这是我的代码: using (var Command = new OracleCommand("PMH.Que

Cannot Connect to Oracle in C#

I am trying to connect to Oracle in a 32-bit Console Application. I am getting the following erorr. The code (with the exception of host, username, and password change) is below. It is a simple two function project. Any help will be appreciated. I am using C# in Visual Studion 2010 Premium and Oracle 10g.

ODP .NET Parameter problem with uint datatype

After updating from the native .NET oracle data provider to Oracles ODP.NET, I've run into the following issue. I have a stored procedure that is part of a package, and it accepts 32 parameters, all IN but one, designated as an OUT parameter. Anyway, here is the issue I'm having. I have a date parameter passed in as a varchar2 and then 3 other parameters that are varchar2 as well. As

使用uint数据类型的ODP .NET参数问题

从本地.NET数据提供程序更新到Oracles ODP.NET之后,我遇到了以下问题。 我有一个存储过程,它是包的一部分,它接受32个参数,除IN之外的所有IN都被指定为OUT参数。 无论如何,这是我遇到的问题。 我有一个日期参数作为varchar2传入,然后是3个其他参数也是varchar2。 至于其余的,他们都是NUMBER类型。 在我的.NET代码中,所有传递给存储过程的值都是字符串或int,有4个例外。 我有4种类型的UInt32数据。 它们的值对于

Comparing two byte arrays guarding against timing attacks

I want to write a method to compare two byte arrays, but I do not want to use these solutions because I want the method to be resistant to timing attacks. My method essentially looks like: static bool AreEqual(byte[] a1, byte[] a2) { bool result = true; for (int i = 0; i < a1.Length; ++i) { if (a1[i] != a2[i]) result = false; } return result; } (with

比较两个防止定时攻击的字节阵列

我想编写一个方法来比较两个字节数组,但我不想使用这些解决方案,因为我希望该方法能抵抗定时攻击。 我的方法基本如下所示: static bool AreEqual(byte[] a1, byte[] a2) { bool result = true; for (int i = 0; i < a1.Length; ++i) { if (a1[i] != a2[i]) result = false; } return result; } (假定a1和a2具有相同的长度)。 我担心的是,一个足够智能的即时编译器可能会

Jumping to the next "instruction" using gdb

I am attempting to figure the canary value setting and checking mechanism. #include int main(void) { return printf("Hi!n"); } When disassemble the main, I get (gdb) disas main 0x080483f4 : lea 0x4(%esp),%ecx 0x080483f8 : and $0xfffffff0,%esp 0x080483fb : pushl -0x4(%ecx) 0x080483fe : push %ebp 0x080483ff : mov %esp,%ebp 0x08048401 : push %ecx 0x08048402

使用gdb跳到下一个“指令”

我试图找出这个金丝雀值的设置和检查机制。 #include int main(void) { return printf("Hi!n"); } 拆卸主体时,我会得到 (gdb) disas main 0x080483f4 : lea 0x4(%esp),%ecx 0x080483f8 : and $0xfffffff0,%esp 0x080483fb : pushl -0x4(%ecx) 0x080483fe : push %ebp 0x080483ff : mov %esp,%ebp 0x08048401 : push %ecx 0x08048402 : sub $0x14,%esp 0x08048405 : mov %g

Automatically Generate C Code From Header

I want to generate empty implementations of procedures defined in a header file. Ideally they should return NULL for pointers, 0 for integers, etc, and, in an ideal world, also print to stderr which function was called. The motivation for this is the need to implement a wrapper that adapts a subset of a complex, existing API (the header file) to another library. Only a small number of the pro

从标题自动生成C代码

我想生成在头文件中定义的过程的空实现。 理想情况下,他们应该为指针返回NULL,为整数等返回0,并且在理想的世界中,还会打印stderr哪个函数被调用。 这样做的动机是需要实现一个包装器,该包装器将复杂的现有API(头文件)的子集调整到另一个库。 API中只有少数程序需要委派,但尚不清楚哪些程序。 所以我希望使用一种迭代方法,在这种情况下,我运行这个自动生成的包装器,查看所谓的内容,使用委托实现它,然后重复。

How to hash an int[] in c#

I'm trying to think of a way to override GetHashCode() when called from a Vector2[]. This code produces non unique hashes for objects that I know to be equal: I pass the following class the same rectangle, and different hash codes are generated. public Shape(Rectangle r) { edges = new Vector2[4]; edges[0] = new Vector2(0, 0); edges[1] = new Vector

如何在c#中散列int []

我想从Vector2 []中调用时重写GetHashCode()方法。 这段代码为我知道的对象生成非唯一散列:我将下面的类传递给同一个矩形,并生成不同的散列码。 public Shape(Rectangle r) { edges = new Vector2[4]; edges[0] = new Vector2(0, 0); edges[1] = new Vector2(r.Width, 0); edges[2] = new Vector2(r.Width, r.Height); edges[3] = new Vector2(0, r.H

how to open, read, and write from serial port in C

I am a little bit confused about reading and writing to a serial port. I have a USB device in Linux that uses the FTDI USB serial device converter driver. When I plug it in, it creates: /dev/ttyUSB1. I thought itd be simple to open and read/write from it in C. I know the baud rate and parity information, but it seems like there is no standard for this? Am I missing something, or can someone

如何从C中的串口打开,读取和写入

我对读取和写入串行端口有点困惑。 我在Linux中有一个使用FTDI USB串行设备转换器驱动程序的USB设备。 当我插入时,它会创建:/ dev / ttyUSB1。 我认为它很容易在C中打开和读写。我知道波特率和奇偶校验信息,但是似乎没有标准呢? 我是否错过了某些东西,或者有人能指引我走向正确的方向吗? 我很久以前写过这篇文章,只是将需要的位复制并粘贴到每个项目中。 #include <errno.h> #include <fcntl.h> #in
