scalar

I am trying to perform some simple if statements, but all of the newer cmdlets that are based upon [Microsoft.Management.Infrastructure.CimInstance] don't seem to expose a .count method? $Disks = Get-Disk $Disks.Count Doesn't return anything. I found that I can cast this as an [array], which makes it returns a .NET .count method as expected. [Array]$Disks = Get-Disk $Disks.Count This works without directly casting it as an array for previous cmdlets: (Get-Services).Count What is the recommended way to get around this? An example that doesn't work: $PageDisk = Get-Disk | Where {($_.IsBoot -eq

The JavaDoc says: SQLQuery org.hibernate.SQLQuery.addScalar(String columnAlias, Type type) Declare a scalar query result I know what executeScalar is in C#, but this scalar and C# scalar seem to be absolutely different. This is declaring that you want the result of the query to return objects for individual named columns, rather than entities. For instance createSQLQuery("SELECT COUNT(*) AS c FROM Users").addScalar("c").uniqueResult() Will return a single Long . If you specify multiple scalars, the result will come back as an array of Object . Its similar to executeScalar except that it works

I have the following code: $final = array(); foreach ($words as $word) { $query = "SELECT Something"; $result = $this->_db->fetchAll($query, "%".$word."%"); foreach ($result as $row) { $id = $row['page_id']; if (!empty($final[$id][0])) { $final[$id][0] = $final[$id][0]+3; } else { $final[$id][0] = 3; $final[$id]['link'] = "/".$row['permalink']; $final[$id]['title'] = $row['title']; } } } The code SEEMS to work fine, but I get this warning: Warning: Cannot use a scalar value as an array in line X, Y, Z (the line with: $final[$id][0] = 3, and the next 2). Can anyone tell me how to fix this? You

In various articles I have read, there are sometimes references to primitive data types and sometimes there are references to scalars. My understanding of each is that they are data types of something simple like an int, boolean, char, etc. Is there something I am missing that means you should use particular terminology or are the terms simply interchangeable? The Wikipedia pages for each one doesn't show anything obvious. If the terms are simply interchangeable, which is the preferred one? Michael Ekstrand I don't think they're interchangeable. They are frequently similar, but the difference

I'm moving from Java to C++ and am a bit confused of the language's flexibility. One point is that there are three ways to store objects: A pointer, a reference and a scalar (storing the object itself if I understand it correctly). I tend to use references where possible, because that is as close to Java as possible. In some cases, e.g. getters for derived attributes, this is not possible: MyType &MyClass::getSomeAttribute() { MyType t; return t; } This does not compile, because t exists only within the scope of getSomeAttribute() and if I return a reference to it, it would point nowhere
