• Windows Forms Help required with understanding threading

  I've got a function in my program that's made by this logic: SaveItem if CheckSave = true then if Status != 5 then If Revision = "Y" or Status != 0 then SaveRSFiles else bSucces = true end if if bSucces = true then SaveMaItem end if end if Now I noticed that somethimes the application hangs on saversfiles. So I read a little bit about threading and now is my question how can I implement threading into my application Something like this: SaveItem if CheckSave = true then if Status != 5 then If Revision = "Y" or Status != 0 then SaveRSFiles (IN A NEW THREAD) else bSucces = true end if end if If thread finishes, then it needs to fire "SaveMaItem" (if bSuc ...Show All

• SQL Server Database Snapshots Performance

  Hi, I'm developing a Data Mart and i'm experiencing a performance gap between my fact table and its snapshot. I create snapshot with the istruction: CREATE DATABASE DB_SNAP ON ( NAME = DB_SNAP_Data , FILENAME = 'C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\Data\ DB_SNAP_Data .ss' ) AS SNAPSHOT OF DB ; And it works. But executing queries on the snapshot result very "low". Can anyone tell me why Tanks. F. There is a section in Books Online titled "How Database Snapshots Work" which shows the extra level of redirection for snapshots. For a newly created snapshot, the data will not be in cache so it might take a little while to pull the data into the buffer pool. Once it ...Show All

• Visual Studio How can we label a particular file and pull only those files that match a particular label?

  How can we label a particular file and pull only those files that match a particular label Example: Label file \level1\level2\level3\john.h as "Label1" Get all files tagged with label1 from \level1. Only john.h should be retrieved. You have to manually loop over every item underneath level1 recursively, then try to fetch the labeled version of each item. (You could optimize this by checking subfolders for the label, then pruning those parts of the tree.) It's more of a workaround than a real solution, admittedly. ...Show All

• Visual Studio Express Editions Can't install VC++ Express from .iso on CD

  I downloaded the Visual C++ Express .iso file and burned a CD ROM so I can install it on a machine that is not connected to the network. The PC has VS6.0 on it but nothing after that. I successfully extracted all the files to a directory on my hard drive, then clicked on setup.exe. Part way through, a box pops up telling me to "insert disk" because setup is looking for dotnetfx.exe. It wants me to insert the "Microsoft Visual C++ Express Edition - ENU disk1" but all I have is the CD ROM with the .iso. The dotnetfx.exe file is there, under wcu\dotNetFramework\, so I don't know what's going on! The "insert disk" window will only accept a path to one of my CD ROM drives... if I try to point it to the location ...Show All

• Architecture UML Tools for our company... VB.NET and Visual Studio.NET 2003

  Hi, I am a newly employeed at a software development company. This company has not previously used UML for deveoping its applications. I would like to document our application using UML and since I know some UML, it is up to me to suggest an application to do this. We use VB.NET and Visual Studio.NET 2003 and the application should at least support Use Case Diagram, the Sequence Diagrams and Class Diagrams. The application should not be too bloated with functions that we are not gonna use, just the UML diagrams mentioned, and not to expensive. What UML Tool are you at other companies using Can you recommend any I personally use Pacestart UML Diagrammer and I like that software. I also have used Rational Rose, which is good but too ...Show All

• Visual Studio 2008 (Pre-release) Media Center API for standalone WPF

  Hi guys. Can i use Media Center API in standalone wpf apps I want to use the remote control functionality in wpf applications. Thanks. Currently there is only support for XAML Browser Application (XBAP) integration with Media Center on Windows Vista. If your objective of using standalone WPF apps is solely for the full trust privileges such apps enjoy, then you can launch the XBAP from local machine, or even if deployed from the Internet, employ the ClickOnce Trusted Publisher -based elevation model. This is kind of how the dashboard on the HP Touchsmart PC is modeled. ...Show All

  I have added new columns to the data grid and am now adding new Template Fields to the code behind the page.

• Windows Forms How do I change the source of a datagrid?

  I have a very simple form with 1 grid and 2 buttons on it. I would like to set the grid's datasource from one table adapter to another. I tried seting up 2 separate databindings and changing the datasource from one to the other, with no luck. Here's the code that I am using to change the datasource and then fill it. Any suggestions would be greatly appreciated. this .dataGridView1.DataSource = dataSet1BindingSource1; this .sO_TYPETableAdapter.Fill( this .dataSet1.SO_TYPE); Thanks, jay0555 Thank you so much. Here's my final code that worked. I also had to remove the properties that I had set for the grid. They were holding it up. dataGridView1.DataSource = null ; this .dat ...Show All

• Visual C++ How do I copy a class instance with a vector of instances of it's own type?

• Visual Studio How to create a "custom build" project with VS2005?

  I am designed a "custom build" project under VS2005, the purpose of this project is to initialize a database environment (the build is based on NAnt but it could have been MSBuild). Question: how can I define a "custom build" project under VS2005 For now, I have simply used a "solution directory" instead of a project. Is there a better way to proceed Thanks in advance, Joannes http://www.peoplewords.com Could you be more specific about what a "custom build" is . When you say it is based on nant it makes me think that you have a target as part of a nant build file which has tasks which will fill the database. You could rewrite this in MSBuild (or just call nant on your nant ...Show All
