I would assume that this is covered in the C++ Standard, but I've not been able to find it. I am writing some templates that are going to do arithmetic on their non-type integral parameters, and I find I need the equivalent of MAX_INT for the parameter 'x' in a template like template <int x> Foo. Ideally someone could point me to the pa...

Simple problem: I am subclassing a FilterInputStream in Scala, which has a read method: public void read(byte [] b,int offset,int len) The data being read will be put in b, but as parameters are "vals" in Scala methods, I see no way to properly subclass this.

One simply filters the type of row - there is a column called action, and the user selects one of the distinct values from the database in a dropdown box, and the gridview only displays the rows with that value in the action column. On it's own this w...

I built a report with one parameter being a menu of names, and the default value being <ALL> Clients wanted the default to be the person logged in. I can easily get User!UserID the default for a text box, but if I change the menu from names to IDs, it will not pre-select it on the menu. Instead, it adds the "" thing to the top of the ...

The problem is that upon editing, instead of adding the ex...
