parameters

问题 I would like to know how the doMonitorization method can be called when the param1 is used (param defined and used on the methods of the TestClassGeneralMeasuraments Class) which has the correct annotation that has a interception AspectJ definition as the bellow code shows. package monitorization; import org.aspectj.lang.JoinPoint; import org.aspectj.lang.annotation.After; import org.aspectj.lang.annotation.Aspect; import org.aspectj.lang.annotation.Pointcut; @Aspect public class

问题 I am trying to do a method that its function named is factor_count that accepts an integer as its parameter and returns a count of its positive factors. For example, the six factors of 32 are 1, 2, 4, 8, 16, and 32, so the call of my method should return 6. int factor_count(int number) { int i, count; for (i=1;i<=number;i++){ if(number%1==0){ count = number%i; } } return count; } 回答1: % is the modulo operator. It's remainder after a division. If the remainder after division is zero you should

问题 I'm trying to make a parameters estimation on Lotka-Volterra model with Scilab (I am a total neophyte). When I try to run the script, Scilab warns about incoherent subtraction. I guess my problem is the same as in this topic, but the solution there uses a Matlab function. Here is my script: // 1. Create Lotka Volterra function function [dY]=LotkaVolterra(t,X,c,n,m,e) IngestC = c * X(1) * X(2) GrowthP = n * X(1) MortC = m * X(2) dY(1) = GrowthP - IngestC dY(2) = IngestC * e - MortC endfunction

问题 I have a dummy shell program that takes arguments. However, I want it to take no arguments and instead provide a prompt to let the user input the name of executable program and parameters. For example: $dummyshell >(executable program and parameters go here) Here is the code I have so far: #include <stdlib.h> #include <stdio.h> #include <errno.h> #include <string.h> #include <unistd.h> #include <sys/types.h> #define BUFFER_SIZE 1<<16 #define ARRAY_SIZE 1<<16 void parseCmdArgs(char *buffer,

问题 I want to access a MSBuild variable inside an unit test, which is a .NET 4.5 class library project (classic csproj), but I failed to find any articles discussing a way to pass values from MSBuild into the execution context. I thought about setting an environment variable during compilation and then reading that environment variable during execution, but that seems to require a custom task to set the environment variable value and I was a bit worried about the scope of the variable (ideally, I

问题 I am using file DSN for connecting to Sybase database. Login password is encrypted and is stored with EncryptedPassword keyword in the .dsn file. I have the requirement to change the database password and update the DSN accordingly. I am using SQLDriverConnect to connect to the database and SQLWriteFileDSN to modify the .dsn file. Is there any way to encrypt the new given password same way Sybase does(keyword or special tag or some thing?).? Some limitation: I know its not recommended to

问题 I'm trying to get a value from Microsoft SQL Server stored procedure . Totally I need to return two values. As you see below one of them is accessible by return and the other is accessible by a output parameter. I run this code in WPF(C#): public int InsertCustomerEntranceLogWithOptions(String cardNumber,int buy, int score, out int logID) { SqlCommand command = new SqlCommand( @" --declare @id int, @logID int exec @res = Insert_CustomerEntranceLog_WithOptions @cardNumber, @buy, @score, @logID

问题 I'm learning about vectors in Accelerated C++ by Andrew Koenig and Barbara Moo. Can anyone explain the difference between these? vector<string> x; and vector<string> x(const string& s) { ... } Does the second one define a function x whose return type must be a vector and whose return value is stored somehow in x? The exact code from the book starts like this: map<string, vector<int> > xref(istream& in, vector<string> find_words(const string&) = split) { 回答1: vector<string> x; This is a

问题 The following ExecuteNonQuery returns sql error: ORA-01745: invalid host/bind variable name , but as you can see, these parameter names are not reserved words. Why else would I get this error? (I tried to rename all of my parameters). public bool AddArticle(ArticleModel articleModel) { bool result = false; using (OracleConnection conn = new OracleConnection(BasicConnection.connectionStringOracle)) using (OracleCommand command = conn.CreateCommand()) { conn.Open(); using (var trans = conn

问题 I have the code that change the state of boolean property on mouseclick, depending on name of the clicked object: private void Grid_MouseLeftButtonDown(object sender, MouseButtonEventArgs e) { FrameworkElement feSource = e.Source as FrameworkElement; switch (feSource.Name) { case "r1s1": if (r1s1.IsSelected == false) r1s1.IsSelected = true; else r1s1.IsSelected = false; break; case "r1s2": if (r1s2.IsSelected == false) r1s2.IsSelected = true; else r1s2.IsSelected = false; break; .............
