我在一个较大的应用程序中使用管道时遇到了问题,所以我创建了一个最小的测试应用程序来研究这个问题。
我正在创建一个管道:
Dim sa As SECURITY_ATTRIBUTES
Dim R As Long
sa.nLength = Len(sa)
sa.bInheritHandle = 1
R = CreatePipe(hRead, hWrite, sa, 0) //hRead declared globally
Debug.Print "CreatePipe: " & R
然后我从上面读到:
Const BufSize As Long = 1024
Dim Buf
我正在尝试使用下面的VHDL代码片段读取一个英特尔.hex文件。我的合成器在代码中应该检查和丢弃行开头的“:”字符的部分有问题。综合工具给出了这个错误“调用过程没有主体”(行标记为注释)。我从来没有见过这个错误,也不知道它意味着什么。是否存在此错误的解决方案(或丢弃“:”字符的替代方法)?
function Load_Data(constant x: in integer) return ROM_Data is
use std.textio.all;
use ieee.std_logic_textio.all;
file ROMFILE: TEXT open READ
我有一个用python编写的程序,我用pyinstaller将其转换为exe文件。现在,我想通过使用VBA代码调用它,在另一台PC上运行它。为了直接从程序中获得输出,我使用了我在互联网上找到的这段代码:
Private Declare Function CreatePipe Lib "kernel32" (phReadPipe As Long, phWritePipe As
Long, lpPipeAttributes As SECURITY_ATTRIBUTES, ByVal nSize As Long) As Long
Private Declare Function
我有个简单的问题。我无法从文件的端点读取到直接的端点.下面是代码片段:
public class SampleTwo {
public static void main(String[] args) throws Exception {
final CamelContext camelContext = new DefaultCamelContext();
camelContext.start();
camelContext.addRoutes(new RouteBuilder() {
@Override
public void c
我有一个这样的代码
Create thread_1 and bind task 1 to that;
Create thread_2 and bind task 2 to that;
Create thread_3 and it monitors the keyboards and work as follow:
while(true){
get the next key;
if (the next key == 'p')
pause_the_code();
if (the next key ==
我有一个服务,它创建一个进程,然后释放它的内存。我使用createprocess()函数,然后关闭进程和线程的句柄,这是我的代码:
if (CreateProcessA(NULL,
zAppName,//{ pointer to command line string }
NULL, //{ pointer to process security attributes }
NULL, //{ point

我正在为我的设计编写一个通用测试平台,通过一个非常标准的总线与RAM通信。我参考了一些例子,并写成这样:
signal memory: mem_array;
signal mem_address: std_logic_vector(31 downto 0);
signal mem_data: std_logic_vector(31 downto 0);
signal mem_read: std_logic;
signal mem_write: std_logic;
