As you’ve found, you can’t do this. As a workaround I normally supply a delegate that can create objects of type T: public class A { public static void Method<T> (T a, Func<float[,], T> creator) { //…do something… } }
From the OPENQUERY documentation it states that: OPENQUERY does not accept variables for its arguments. See this article for a workaround. UPDATE: As suggested, I’m including the recommendations from the article below. Pass Basic Values When the basic Transact-SQL statement is known, but you have to pass in one or more specific values, use code … Read more
You can change what foo points to using y: Foo foo = new Foo(“1”); void Bar(ref Foo y) { y = new Foo(“2”); } Bar(ref foo); // foo.Name == “2”
Something like: $query = explode(‘&’, $_SERVER[‘QUERY_STRING’]); $params = array(); foreach( $query as $param ) { // prevent notice on explode() if $param has no ‘=’ if (strpos($param, ‘=’) === false) $param += ‘=’; list($name, $value) = explode(‘=’, $param, 2); $params[urldecode($name)][] = urldecode($value); } gives you: array( ‘ctx_ver’ => array(‘Z39.88-2004’), ‘rft_id’ => array(‘info:oclcnum/1903126’, ‘http://www.biodiversitylibrary.org/bibliography/4323’), ‘rft_val_fmt’ => … Read more
I think it is not valid because the constructor isn’t always the only point of entry of the class (I am talking about copy constructor and operator=). So suppose you are using your class like this : MyClass m(string s); MyClass *pm; *pm = m; I am not sure if it would be so obvious for … Read more
Dirk’s answer here is everything you need. Here’s a minimal reproducible example. I made two files: exmpl.bat and exmpl.R. exmpl.bat: set R_Script=”C:\Program Files\R-3.0.2\bin\RScript.exe” %R_Script% exmpl.R 2010-01-28 example 100 > exmpl.batch 2>&1 Alternatively, using Rterm.exe: set R_TERM=”C:\Program Files\R-3.0.2\bin\i386\Rterm.exe” %R_TERM% –no-restore –no-save –args 2010-01-28 example 100 < exmpl.R > exmpl.batch 2>&1 exmpl.R: options(echo=TRUE) # if you want … Read more
I’m thinking that your output parameter is coming back with a DBNull value. Add a check for that like this var outputParam = dataAccCom.GetParameterValue(IDbCmd, “op_Id”); if(!(outputParam is DBNull)) DataTO.Id = Convert.ToInt64(outputParam);
# Delay-bind script-block argument: # The code inside { … } is executed for each input object ($_) and # the output is passed to the -NewName parameter. … | Rename-Item -NewName { $_.Name -replace ‘\.txt$’,’.log’ } The call above shows an application of a delay-bind script-block ({ … }) argument, which is an implicit … Read more
A parameter is a variable in a method definition. When a method is called, the arguments are the data you pass into the method’s parameters. public void MyMethod(string myParam) { } … string myArg1 = “this is my argument”; myClass.MyMethod(myArg1);
No, function parameters are not evaluated in a defined order in C. See Martin York’s answers to What are all the common undefined behaviour that c++ programmer should know about?.
