• Architecture Windows Service OR Win App

  I have been told to write a windows service which 'periodically' checking for messages and application updates from the web service. The user has the choice to download updates and messages automatically or to be prompted to download them when they are available. Note: A Message may contain documents. Now my question is is it the right approach to do this using a windows service or windows app/form. Please help me out on this. Thanks kash In my opinion, there should not be any problem while using win service as you are going to check for it periodically and the process will be running in background. You might need to think of more while trying to prompt as Windows Service does not support UI. ...Show All

• Windows Forms copying one object to another,..

  Hi, I have a namevaluecollection object which is being used in 2 different threads. One thread updates the values and the other reads it. In reading thread I want to read the namevaluecollection in a local object and then use that local object to read and then display it so that the reading thread uses the namevaluecollection object for the least amount of time. How can I copy the shared namevaluecollection to a local object such that after copying it to the local object, the shared namevaluecollection is set free for the other thread to use... I believe doing this does'nt free the ShareNameValueCollection to be used safely by the other thread: LocalNameValueCollection = ShareNameValueCollection because, say, if I make ...Show All

• Software Development for Windows Vista ToolboxBitmap

• SQL Server Trying to connect to SharePoint database

  I am having trouble connecting to the SharePoint database on my web server. Our company intranet is accessed by http://webservername/ and the SharePoint site is accessed by http://webservername:2020/ (I wanted to put it on a different port to not interfere with our old intranet). Anyway, I need to connect to the DOCS table on the content database, but I can't seem to connect with SQL Server 2005. When I connect to webservername I see our company database but I don't see anything that has to do with our SharePoint stuff.

• Windows Forms Simple Form customisations

  Hi, I'm at the moment learning C# through Visual C# Express edition and have a few questions. My first is that in my custom web browser I am designing how do I alter it, so that after I type my URL in my text box, it makes my browser go to that site as well as being able to press a GO button form. Also how I make it so that when I press Maximize the parts of my form scale to my Maximized window. To me these will seem like silly questions to most of the experienced and knowledgeable programmers on here, but I am only 15 so please be kind! Thanks for the Help. Hi, Here step by step instruction. With the empty form in design mode, drag a new WebBrowser control, a text box and a button. Place the web browser to cover the bott ...Show All

When I run some games programmed with Visual Basic, I get the following error: Run-time error '53': File not found I am running Windows ME (I wonder if that can help). If anyone could help me, I would be really grateful. Thanks.

• SQL Server autonomous transactions

  Is there any equivalent to Oracle's autonomous transaction in sqlserver. No. There is no way to do this in SQL Server right now. You can write extended SPs or CLR SPs (SQL 2005) that performs a different connection to the database. But this approach has it's own limitations and scalability problems. One workaround that will work in SQL2000/2005 depending on your requirements is to use a table variable within a transaction to dump the information. Table variables do not participate in user transactions so you can later retrieve the rows and dump them into an error log table for example after the transaction has been rolled back. ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. unloading model resources

  Im trying to figure out how to manually unload models/textures/shaders ect. Halp me Intertron! DirecX runtime is a COM compliant API. It means a lot of things, but especially for your concern that each allocated object has a reference counter. The idea behind this counter is to deallocate the COM object as soon as counter's value falls down to 0. The counter is incremented at creation time, on a call to the COM base interface IUnknow::AddRef or IUnknow::QueryInterface. To decrement it, call IUnknow::Release function and the object will be automatically destroyed if its counter value is 0. Anyway, you'll should not care about what is the exact counter value, simply manage your own references to your objects and it will work. For mo ...Show All

• Visual Basic from list of tables to combobox: what the best way of doing it?

  Hi, From a lot of help from this foum and the Net, I have managed to get a list of tables from my access database with these line of codes: Dim vrn As String () = New String () { Nothing , Nothing , Nothing , "TABLE" } Dim schemaTable As DataTable = objConnection.GetSchema( "Tables" , vrn) DataGridView1.DataSource = schemaTable Using GetSchemOledb also worked fine but I think GetSchema needs much less typing . Since GetSchema returns a DataTable, is it possible to put the list of tables in a combobox if this is possible can somebody reccomend the best way to do it I think it involves getting the names from the TABLE_NAME column which have TABLE as property in the TABLE_TYPE column. Any hint/ ...Show All

• Visual Studio Invisible dialog box kills Studio?
