  • VS 2010 SQL Update for SQL Statement

    - by Mike Tucker
    Please bear with me as I'm just beginning to learn this stuff. I have a VS 2010 Web project up and I'm trying to understand how I can make a custom UpdateCommand (Because I chose to write my own SQL statement, I do not have the option for VS 2010 to auto generate an update command for me.) Problem is: I don't know what the UpdateCommand should look like. Here is my Select: SELECT * FROM Dbo.MainAsset, dbo.Model, dbo.Hardware WHERE MainAsset.device = Hardware.DeviceID AND MainAsset.model = Model.DeviceID Which, VS 2010 turns into: SELECT MainAsset.pk, MainAsset.img, MainAsset.device, MainAsset.model, MainAsset.os, MainAsset.asset, MainAsset.serial, MainAsset.inyear, MainAsset.expyear, MainAsset.site, MainAsset.room, MainAsset.teacher, MainAsset.FirstName, MainAsset.LastName, MainAsset.Notes, MainAsset.Dept, MainAsset.AccountingCode, Model.Model AS Hardware, Model.pk AS Model, Model.DeviceID, Hardware.Computer, Hardware.pk AS Expr3, Hardware.DeviceID AS Expr4 FROM MainAsset INNER JOIN Hardware ON MainAsset.device = Hardware.DeviceID INNER JOIN Model ON MainAsset.model = Model.DeviceID How would I approach updating one column, say "MainAsset.site" if that's changed in the Gridview DDL? Any help constructive help would be appreciated. Thank you.

  • Constructor for an immutable struct

    - by Danvil
    Consider the following simple immutable struct: struct Stash { public int X { get; private set; } public Stash(int _x) { X = _x; } } This is not working, because the compiler wants me to initialize the "backing field" before I can access the property. How can I solve this?

  • Iterating through a range of dates in Python

    - by ShawnMilo
    This is working fine, but I'm looking for any feedback on how to do it better. Right now I think it's better than nested loops, but it starts to get Perl-one-linerish when you have a generator in a list comprehension. Any suggestions are welcome. day_count = (end_date - start_date).days + 1 for single_date in [d for d in (start_date + timedelta(n) for n in range(day_count)) if d <= end_date]: print strftime("%Y-%m-%d", single_date.timetuple()) Notes: I'm not actually using this to print; that's just for demo purposes. The variables start_date and end_date are datetime.date objects, because I don't need the timestamps (they're going to be used to generate a report). I checked the StackOverflow questions which were similar before posting this, but none were exactly the same. Sample Output (for a start date of 2009-05-30 and an end date of 2009-06-09): 2009-05-30 2009-05-31 2009-06-01 2009-06-02 2009-06-03 2009-06-04 2009-06-05 2009-06-06 2009-06-07 2009-06-08 2009-06-09

  • Where is Prolog used for traffic control systems?

    - by Masi
    The user Laurent had an interesting reply to the question [Why hasn’t logic programming caught on?]: If you look at the influence logic-programming has had in the field of -- air traffic control -- I don't think it can be said logic-programming has not caught on. A question arises: Where is prolog used for traffic control systems on the roads? Why is it used instead of languages, such as C or Python, in such environments?

  • How to programmatically switch to a specific window in compiz?

    - by FossilBit
    Is there a command to tell compiz that we want to bring in front and set focus to a specific window? How should we identify the window in that command? The reason behind this question is the following use-case: Suppose we have a wiki to keep notes of anything interesting we find out. It would be very convenient to have a keyboard shortcut to bring the browser window with our Wiki page in front and start typing immediately then with another key combination switch to the application we were working before I know that "ALT+TAB" switches between the last two used windows but cannot support more complex combinations of applications. E.g Browser+Eclipse+ Wiki If there is a command like the one described, it is easy to add a shortcut to it from KDE or GNOME interface Thanx ...

  • scaffold does not update view

    - by doemsche
    Hi there I have a question to the following procedure: script/generate scaffold product title:string description:text db:migrate #then I generate a migration which adds a column description to the table products and migrate the db again. My question is: why is the field description not added to the project-views? Is that normal rails scaffold behaviour? I think I saw in a video tutorial that the scaffold updates as well the views, which would be very convenient. Thanks in advance for any help!

  • Is it a bad programming practise to have "Public" members inside an "Internal" class?

    - by Amby
    I mean, won;t it be more specific and appropriate if i "only" keep "protected","internal" and "private" members (field,method,property,event) in a class which is declared as "internal" ? I have seen this practice ( having "public" members in an "internal" class) in various code so just wanted to know is it a bad practice or does it has some benefit or advantage. [Only concerned about C#] Thanks for your interest.

  • IList<T> versus Collection<T> as property

    - by Brian Triplett
    I have a class with a internal array field. I want to expose this array as a property, such that it maintains as much funtionallity of the orginal array but does not violate abstraction by exposing the array directly. What are the various methods and pros and cons? I'm thinking specifically about IList<T> or Colleciton<T>

  • TCP Connection Persistent State

    - by TripShock
    Is there any field/option/anything that I can put in a TCP packet (be it a syn or an ack or just plain data) that I can be sure will be returned by the other end intact? For eg. I want to "tag" a particular connection (src, srcport, dst, dstport) with a number that I can always read from a packet belonging to that connection. That means I can identify the connection without using the 4-tuple (as given above).

  • onUpdate in MySQL means?

    - by ajsie
    i know that if you create a foreign key on a field (parent_id) in a child table that refer to a parent table's primary key (id), then if this parent table is deleted the child class will be deleted as well if you set onDelete to cascade when creating the foreign key in the child class. but what happens if i set it to onUpdate = cascade?

  • Can we turn on the iphone's number keyboard WITHOUT using type=number?

    - by Simple As Could Be
    I'm making a webapp, and I'd like an input field to show the Iphone's number keypad. I understand that type=number will make the keypad show the way I'd like. The trouble is that type=number does not support placeholder text. So if I would like this: Expiration Date: [eg: 2010] I can not get it to work, and also show the right keyboard. Is there a way to force the iphone keyboard into number mode without using the number input type?

  • TSql Lookup function

    - by OldMan
    I have a bunch of dimension tables that have unique ID and Name fields. I need a T-SQL function that returns an ID when passed a table name and a value for the name field. I'm guessing the query would build a little query then execute it? Performance isn't an issue since this is a one time ETL thing.
