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
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
I am getting an error in a windows service I'm working on. The service runs twice daily. When it runs at 6:00 PM it works just fine. When it runs at 6:00 AM, I get an e-mail with this stack trace. Does anyone have any idea what the error might be? Oracle.DataAccess.Client.OracleException ORA-03113: end-of-file on communication channel Process ID: 2448 Session ID: 155 Serial number: 5412
我在正在处理的Windows服务中发生错误。 该服务每天运行两次。 当它在6:00 PM运行时,它工作得很好。 当它在上午6点运行时,我会收到一封包含此堆栈跟踪的电子邮件。 有谁知道错误可能是什么? Oracle.DataAccess.Client.OracleException ORA-03113:通信通道上的文件结束进程ID:2448会话ID:155序列号:54127 at Oracle.DataAccess.Client.OracleException.HandleErrorHelper(Int32 errCode,OracleConnection conn,In
I'm trying to connect to my Oracle Database from my new PC. I've just installed Visual Studio and the ODAC. But when I try to do a simple connect Im getting an exception with an empty message, empty source, empty number, just with the error code which is -2147467259.

我试图从我的新电脑连接到我的Oracle数据库。 我刚刚安装了Visual Studio和ODAC。 但是,当我尝试做一个简单的连接我得到一个空的消息,空来源,空数量,只是与错误代码是-2147467259异常。 OracleConnection Prueba; Prueba = new OracleConnection("Data Source=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=XXX.XXX.XXX.XXX)(PORT=1521)))(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=XXXX)));User Id=XXX;
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. I can connect to the database with Oracle SQL Developer with the information set in
我正尝试在32位控制台应用程序中连接到Oracle。 我得到以下的错误。 下面是代码(主机,用户名和密码更改除外)。 这是一个简单的双功能项目。 任何帮助将不胜感激。 我在Visual Studion 2010 Premium和Oracle 10g中使用C#。 我可以使用连接字符串中设置的信息使用Oracle SQL Developer连接到数据库。 --------------- ToString -------------------------- --Oracle.DataAccess.Client。 Oracle.DataAccess.Client.O
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
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
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
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
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
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
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
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。
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
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
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
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
