I've seen other topics that deal with this error but none that seem to correspond to my situation. First of all, my code works completely fine when i run it locally. But when i upload it to the server, i get the error: Parameter '?PuserName' not found in the collection. Here is the C# code: public DataSet GetEmployeeByUsername(strin...
Hello, I am trying to use Shoes and I need to pass it command-line parameters (basically, my Shoes app will be called from another pre-existing app and this would allow me to pre-fill some parts of shoes). Should I then call it using bin/shoes wrapper? It seems I can not pass arguments to shoes wrapper (it concatenates all parameters a...
Hello together and a happy new year 2009! I am programming a simulations for single neurons. Therefore I have to handle a lot of Parameters. Now the Idea is that I have two classes, one for a SingleParameter and a Collection of parameters. I use property() to access the parameter value easy and to make the code more readable. This works...
Let us ignore for a moment Damian Conway's best practice of no more than three positional parameters for any given subroutine. Is there any difference between the two examples below in regards to performance or functionality? Using shift: sub do_something_fantastical { my $foo = shift; my $bar = shift; my $baz = shif...
ClassA* pa = NULL; ClassA* pb = NULL; assignObject(ClassA* pa,ClassB* pb) { pa = new ClassA; pb = new ClassB; } what will be the value of pa,pb after executing the function EDIT how to pass as pointer is the return if pa,pb is NULL ...
In the following jQuery JavaScript code, what value does the parameter "e" take on within the function? I'm having difficulty understanding this because this function cannot be passed an argument elsewhere in the code so how would having a parameter work? And how would I use parameters in such functions that are not named and not called ...
I have 5 parameters and I want to send them to the method: public static SqlCommand getCommand(string procedure, SqlParameter[] parameter) { Sqlcommand cmd; return cmd } Can I send these paramters at one time like this? SqlParameterCollection prm; prm.Add(p1); prm.Add(p2); prm.Add(p3); prm.Add(p4); prm.Add(p5); sqlcommand cmd =...
I often find myself confused with how the terms 'arguments' and 'parameters' are used. They seem to be used interchangeably in the programming world. What's the correct convention for their use? ...
I've run into a really strange bug, that I'm hoping someone can explain. I have a simple std::vector<V3x>, where V3x is a 3d vector (the linear algebra kind.) The following code causes a std::length_error exception to be thrown: std::vector<V3x> vertices; int vertexCount = computeVertexCount(); vertices.resize(vertexCount); // throws st...
I am trying to pass a number to my JavaScript function, but actually a wrong value is getting passed. I am giving the entire code here: <html> <head> <script type="text/javascript"> function test(num) { /*It should alert as 01004 or 1004 but to my surprise it's alerting as 516!*/ alert(num); } </script> </head> <body> <a href="javascrip...
So, I have a method that performs a parametrised LIKE query. The method takes in the search parameter/value in and then it is added to the command ready for the query. It is not working. It should work, and when I code the value to search for directly into the SQL string, sans parametrisation, it does work! When I have it as a paramete...
I have: Request request = new Request(Method.GET, "https://www.awebsite.com/login"); Client client = new Client(Protocol.HTTPS); Response response = client.handle(request); ... response.getEntity().write(System.out); But I don't know how to set the login parameters... I want code that does the escaping etc can switch between get/po...
In C++, arrays cannot be passed simply as parameters. Meaning if I create a function like so: void doSomething(char charArray[]) { // if I want the array size int size = sizeof(charArray); // NO GOOD, will always get 4 (as in 4 bytes in the pointer) } I have no way of knowing how big the array is, since I have only a point...
Parameters are used to protect you from malicious user input. But if the parameter expects a string, is it possible to write input that will be interpreted as sql, so malicious users can use things like 'DROP', 'TRUNCATE', etc...? Are there differences in protection between parameters in asp, asp.net, java and others? See also: Are ...
I'm using a web service and every time I change something on the dataset, it erases all my parameters. The weird thing is, I can execute the web service call from the data tab and it prompts for all my parameters, but if I click to edit the data the list is empty or if I try to preview the report it blows up because parameters are missi...

I have successfully hooked myself up to the SubreportProcessing event, I can find the correct sub-report through e.ReportPath, and I can add datasources through e.DataSources.Add. But I find no way of adding report parameters?? I have found people suggesting to add them to the master report, bu...
I want to turn a program I have into a service so I can use it without logging it. Basically what it does is it backs up specified folders to a specified location using SSH. However the problem I'm running into is I don't know how to tell it these items. I only know how to start, stop, and run a custom command with only an integer with a...
I know of two methods of setting a default parameter, but I would like to know what the preferred method is. function Foo(par1, par2) { if(par2 == null) par2 = "my default" } or function Foo(par1, par2) { par2 = par2 || "my default" } or is there a better way than either of these? EDIT: I would also like to know h...

Is there any way to avoid this page refreshment on each parameter selection. Thanks in advance. Maria ...
