Arbitrary order in SQL query

It seems that in C#, given an instance "a" of some value type "A", one can pass a by reference to functions with signatures of either "void f(object obj)" or "void g(ref A obj)". But passing a into a function with signature "void f(ref object obj)" gives a compile error -- why (This is part of solving the original problem posed here: http://www.csharp-station.com/ShowPost.aspx?PostID=3625 What I need now is a method that accepts a ref to an...

Hello! I am trying to find a minimal class/lib that handles arbitrary precision decimal numbers. I would be happy if this class supported as little as addition, subtraction, multiplication, division and comparisons. For some reason it's quite hard to find such a class on the net. Maybe because it is trivial to implement such a class? The only library I have found so far is MAPM (http://www.tc.umn.edu/~ringx004/mapm-main.html). This...

I hope someone can help me get this graph outputing in proper order. After help from Tom, I got a graph to display output from the previous 12 months and include the average of that output all in the one graph. The output was in the order of the months, but after unioning with the averages SQL code, the order is lost. Below is the full sql code that is the data source for the graph: SELECT (Format(.,"mmm"" '""yy")) AS Month,...

i have a (hopefully) small problem. i have created a system where a user enters customer information into a table through a form. this table has no primary key. there are 9 fields on the form to be filled in, one of which is a date field. right now, i've been using this db myself and have entered only 10 days of sample data to check my calculations but i realized that there may be times when i need to add a record that was missed that...

I have the view below and if I use vwRouteReference as the rowsource for a combo box in an MS Access form or run "SELECT * FROM vwRouteReference" in SQL Query Analyzer, the rows don't come through sorted by Numb. Everything I've read on the web suggests that including the TOP directive should enable ORDERY BY in views. Does someone have an idea why the sorting is not working correctly for this particular view? thanks. CREATE VIEW...

Newbie question here. It's been a while since I've done C programming, and I hit a wall last night. Let's say I have a three dimensional array, like so: int p = {{{0,0,0}, {1,1,1}, {0,1,0}},

Greetings, For user actions on a wxWidget that trigger multiple events for that wxWidget, is the order those events are processed in undefined, and therefore arbitrary from one platform (ie Windows) to the next (ie Linux)? Specifically, I have a convience aggregate class that combines a wxStaticText with a wxComboBox, as I often need those two at the same time. The aggregate catches events from the wxComboBox

Hi everyone. I've recently written a classic asp website which uses an MS Access datasource. I know this is less than an ideal data source as it has limited functionality. I have a search form on my website which allows users to define parameters and return results accordingly. The problem i have is a need to return these results in a random order each time. With SQLServer i know NEWID() would do the trick - used this many times before...

I'm looking for a way to invoke methods with an arbitrary number of parameters of arbitrary type from within a single method, when those parameters are known at the time of invocation of the containing method. I don't see a reason why this shouldn't work. I also can't find the language feature which implements it. More details below. As part of the creation of a set of classes for doing unit testing I want to create a generic...

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>". The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed. This is as boiled down as I can make it. Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Dear forum friends, With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...

Hello I'm a network technician in training and I need your help. I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs. The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols. I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
