• Windows Forms Editing runtime textboxes

  Hi guys, I have a foreach loop that creates runtime textboxes. The textboxes getting filled from the database. My code; foreach ( DataRow dr in scoretable.Rows) { // Creating new textbox scorebox = new TextBox (); scorebox.Name = "scorebox" + i; scorebox.Width = 22; scorebox.Height = 20; scorebox.Location = new Point (x, y); scorebox.Text = dr[4].ToString(); panel1.Controls.Add(scorebox); } Now when I run it, I get the textboxes with the scores from the database on my form. But I would like to to edit some scores and update it to the database. For that I am using this code; foreach ( DataRow dr in scoretable.Rows) { string id = dr[0].ToString(); ...Show All

• SQL Server partitioned views Explain Plan

  Hello I created a partitioned view on my database db1 and It comes from the UNION ALL of 2 tables (I split 1 very big table in 2 smaller tables... Horizontal partition!!) that are on the same db1. When I query them I receive in the EXECUTION PLAN an Item called CONCATENATION of both input tables, This seems to be more expensive than using only one big table so partitioning the big one gets none sense.. I would like to know if this is normal and If I'm doing well with partitioning. Please see the script below: CREATE TABLE [dbo].[TREP_NOVEDADES_2006] ( [NMSEC_NOVEDAD] [numeric](12, 0) NOT NULL , [CDCONCEPTO] [varchar] (12) NOT NULL , [CDTIPO_VALOR] [char] (1), [CDPRECIO] [varchar] (12), [CDTIP_HECT_DTO_PAG] [varchar] (2), [FEG ...Show All

• .NET Development 64 bit remoting app searching for VJSharpCodeProvider

  We have a remoting app we are currently trying to port to 64 bit. It is written in C++/CLI. Whenever we try to connect to our application on the server throws the following exception: The assembly with display name 'VJSharpCodeProvider' failed to load in the 'LoadFrom' binding context of the AppDomain with ID 2. (Full exception included in the bottom of this message). We do not use any J# in our application. As there is no x64 j# runtime I am at quite an impass as to what to do. It may be worth noting that we are connecting from a 32 bit client. I would be thankful for any suggestions.

• Visual Basic Date to string

  Hi all i have taken a textbox named txt_date where date will be entered. now when i save it into microsoft sql server 2000 it saves one and only date "10/01/1900" though i enter any date in txt_date.text(textbox) now i think i would have to convert the value of txt_date.text in to string from date format. Can anyone pls tell me command line for the same... or there is any other way to save value of txt_date.text directly without converting... thanks & Regards Vimal What do you mean converting the value of a textbox into a string from date It's already a string. The SQL server expects dates to be formatted in a distinct way. If it saves 10/01/1900 no matter what date you input (if you do), it is probabl ...Show All

• SQL Server Use of public variables

  Hi, I'm actually using global public variables in the custom code of my reports. Is there a "chance" that , if the report is executed at the same time by two users, values calculated for an user will be crushed by other user's execution Thanks in advance. Gregory. It sounds like you are using public static variables. If you need to be 100% certain to avoid values being calculated by other users, you can make each of the shared variables a hash table based on user ID (i.e. =Globals!UserID). -- Robert ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Dynamically casting an object of unknown type

  Hello everyone! I think I've got a tough problem for you. I've got a List<object> full of various types of objects, and I want to grab an element from the list and cast it back as the type of object it actually is. Ideally, what I would do is something along the lines of: List<object> objects = new List<object>(); MyClass instance = new MyClass(); objects.add(instance); object something = objects[0]; Type somethingtype = something.GetType(); somethingtype variable = (somethingtype) something; this works fine except for the last line. Once I have the type of the object, I can't use that to either declare a new variable of that type, nor can I use it for casting (as far as I know). Does anyone know of a way to use Type info ...Show All

• .NET Development Problem with remoting, works, then mysteriously dies

  I have an application that creates a marshaled object, the lifetime is server controlled. This is a very basic application, all it can do (currently) is return version information. The problem, is that when I run the server, it appears to be running flawlessly. No errors. The client connects, retrieves the version number, and disconnects (just closes the client, can't call disconnect() on a proxy). This works for about 3-15 minutes, then the client starts recieving remoting error "Requested Service Not Found" I don't know why this isn't working. I've written remoting apps before, and this follows the template exactly, but this one quits unexpectedly. It works again when the application is restarted. No errors are thrown The comp ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Multiplayer & C# XNA

  Hi, I've downloaded and installed the XNA Game Studio Express (beta) and then gone through the tutorials. All is working great and I have a couple of simple stand alone 2D games working. I would now like to try and make a simple 2D or 3D XNA game with multiplayer capability in mind. Now I have searched through the forum and FAQs and found that multiplayer is not CURRENTLY available for the Xbox. This is fine as I'm new to all this and I’d like to develop my first multiplayer game as more of a learning experience than anything else so am happy to just start on Windows XP. For multiplayer on Windows XP one of your posts suggests using System.net but doesn’t go into any other detail or point to a site ...Show All

• Windows Forms OnClick preceding OnEnter

  VS 2005 / XP Pro -- both with all service packs It is my understanding that the OnEnter event should precede most (all ) other events for a control but... Our application has a form on which is a Tab-control. We load a number of controls dynamically onto this Tab-control -- ComboBoxes, CheckListBoxes, and TextBoxes. We haven't checked all the Tabs, but on at least one of the Tabs the OnClick/OnMouseClick event precedes the OnEnter event for the ComboBoxes and CheckListBoxes (but not the TextBoxes). Controls that are added at design-time on other Forms' Tab-controls have the events fire in the expected order -- OnEnter and then OnClick/OnMouseClick. Is my understand of the sequence of events erroneous or can someone g ...Show All
