parameter-passing

问题 I've been trying to figure out how to pass parameters from the Loaded="" event. I asked a question here: How would I go about passing a parameter on Loaded=" "? and was guided in the direction of InvokeCommandAction. Issue is I am unable to figure out how to actually use the InvokeCommandAction to call my method. My XAML: <Expander x:Name="Greeting_And_Opening_Expander" ExpandDirection="Down" IsExpanded="True" FontSize="14" FontWeight="Bold" Margin="5" BorderThickness="1" BorderBrush="

问题 This question already has answers here : Is there a way to provide named parameters in a function call in JavaScript? (10 answers) Closed 4 years ago . Calling a Javascript function with something like someFunction(1, true, 'foo'); is not very clear without familiarity with the function. I have seen and used the style where comments are inserted to name the arguments: someFunction(/*itemsToAdd*/1, /*displayLabel*/ true, /*labelText*/ 'foo'); But when it gets beyond 3 or more parameters, it

问题 Using the Deployment Toolkit, is it possible to launch a Java Web Start application through the function deployJava.launchWebStartApplication . I would like to pass one additional dynamic information to the application, either as argument or as system property. I saw that is is possible to define JVM argument for applets: using the parameter java-vm-args I could define system properties with -D . But i didn't find anything for javaws applications. Of course, a solution can be implemented by

问题 If we modify the content of the array passed as parameter inside a method the modification is done on the copy of the argument instead of the original argument hence the result is not visible. What is the process that happens when we call method that have reference type argument? Here is the code sample of what I want to ask using System; namespace Value_Refrence_Type { class Program { public static void Main() { int[] callingarray = { 22, 200, 25485 }; abc(callingarray); Console.WriteLine(

问题 So I've got a "daily dashboard" report in SSRS 2005. It has a parameter, @pDate, which defaults to "=Now". I'd like to use this same report in a linked report to show yesterday's final dashboard (which would then be mailed out via subscription), and override the parameter default with another expression, "=dateadd(d,-1,Now)." But when I change the default parameter, I get a data mismatch error (natch). I'm assuming that's the end of the line and I just need to deploy a copy of the daily

问题 Typically when developing I would use meteor run --settings settings.json . This works fine and can view the settings in the browser with Meteor.settings on the console. I am now build for production, using meteor build , I've looked at the documentation and there is nowhere to add settings during the build process. So the build runs and I have my .tar.gz file, it's loaded to production and then I untar/compress the folder and run the start script. It enters the program with npm start and the

问题 Should I pass std::string by value or by reference to one function. This function store this values in member variable of class. I am always confuse when about pass by value or reference. Please clear my confusion about this. Here is code : class DataStore { public: void addFile(const string& filename, const set< std::string>& filePaths) { if (dataStoreMap.insert(make_pair(filename, filePaths)).second) { cout << "Data Added" <<endl; } else { cout << "Data not Added" << endl; } } private: //

问题 I am really struggling in my efforts over the past 2+ years to try to learn how to use pundit. I am trying to write scoped policies, so that different users can receive objects based on the scope class that they fit into. I have asked several questions on the same topic previously, but I'm not getting any closer to a solution. My recent questions are: here, here, here, here, here and here. There are several others but these give the general picture, that I am struggling with the fundamentals

问题 I want to create a function that returns all the names of a certain class as a string list. Based on the previous solution / question I tried to this code with no success function GetClassElementNames (TObject ) : TStringlist ; var LCtx : TRttiContext; LMethod : TRttiMethod; begin try LCtx:=TRttiContext.Create; try // list the methods for the any class class for LMethod in LCtx.GetType(TObject).GetMethods do result.add(LMethod.Name); finally LCtx.Free; end; except on E: Exception do result

问题 I was trying to implement function with variable arguments but was getting garbage values as output.I have referred to this article before trying to implement on my own.Could anyone help me out with this code as I am unable to understand what's wrong in this code. /* va_arg example */ #include <stdio.h> /* printf */ int FindMax (int n, ...) { int i,val,largest,*p; p=&n; p+=sizeof(int); largest=*p; for (i=1;i<n-2;i++) { p+=sizeof(int); val=*p; largest=(largest>val)?largest:val; } return
