• SQL Server shrink tempdb

  I have a sql2000 server that has a 24 /7 uptime. The tempdb size is increasing rapidly. it was 4 Gbs and i restarted the sql server to shrink the tempdb size which worked fine. but now after 1 week then tempdb size is almost 1.5gbs. Is there anyway that i can shrink the tempDb without restarting it. Asking the users to stop using for a certain timeframe after every month or so seems like a hassle for the users. Steven Trout wrote: I found the same result with a search engine, but is there any reason not use to SQL Enterprise Manager If you right-click on the tempdb, All Tasks, you get the option to shrink the database there. Is that a bad idea No. That's equivalent to 'dbcc shrinkdatabase'. ...Show All

• .NET Development Xml and database

  hi frnds, how do i put the data in a xml file into the database can anyone paste sample code out here. thanx in advance. rawky Hi, you can simply read your XML as a source of data for DataSet like this DataSet ds = new DataSet(); ds.ReadXml("path"); second step is to update/insert your DataSet into the database using DataAdapter. SqlDataAdapter adapter = new SqlDataAdapter("sql", SqlConnection); adapter.Update(ds, "tableName"); before doing this you have to have an Update or Insert command created and assigned to the data adapter like this: adapter.UpdateCommand = cmd; where cmd is an instance of SqlCommand. this will tell your adapter how to map columns from DataS ...Show All

• Windows Forms Control DragDrop event

  Hi, I have my custom control on the toolbox and wanna handle the event that is fired when the usar drags the control from the toolbox to the form designer in design-time. How can I do this what is the event I tried onDragDrop but it is never fired. really appreciate your help, D You'd have to write a Visual Studio extension to do that. Your control has not been instantiated during the drag-drop from the toolbox to the form so it can't intercept anything. What are you trying to accomplish by knowing when a control is dropped on a form ...Show All

• Visual Studio 2008 (Pre-release) Custom Window

  I am creating a custom window that looks similar to the Office 2007 UI. I was able to create an appropriate ControlTemplate/Style with dragging and "Close", Maximize/Minimize buttons etc... But here' the question: What's the best approach to have it encapculated in the separate class/component so I can easily re-use this style for other windows in the app Well, Alex, one ulgy trick you can do here is that, you define the OfficeWindow class in the standalone assembly, and apply the following attribute: [assembly: XmlnsDefinition ( "http://schemas.microsoft.com/winfx/2006/xaml/presentation" , "Lean360.Application" )] This can fool the XAML parser into believe that your custom Of ...Show All

• Windows Live Developer Forums Livecall.exe backgound process

  I have been using Windows Live Messenger for months and today I clicked on the livecall button option. I closed the livecall window and never made any changes but now whenever I open Live Messenger it automatically loads the livecall.exe process which stays resident and uses 17-18MB of ram. This process is just a resource hog as I don't use the service at all and can find no way to set Live Messenger to not load this process upon startup. Can anyone tell me how to tell live messenger to not load this process on startup anymore I am using Windows Live Messenger version 8.1.0178.00 on XPSP2. To get rid of this pesky RAM-hog, the secret is: 1) move the livecall.exe, the softphone.dll's (x 3) and the pcsexe ...Show All

• Visual C# How to navigate between Forms using Back Button.

  Hi All, I'm new to this Forum - as a new learner of C#. In one of my test programs in .NET Compact Framework I have an initial form named FormA. FormA consists of a Button, clicking which FormB opens up. FormB has a Back button, which is supposed to take me to the initial page FormA once again. How do I achieve this In my Initial FormA the Button click that will open up FormB looks as below: private void cmdButton1_Click(object sender, EventArgs e) { // Create an instance of the form. if (Global.refFormB == null) { Global.refFormB = new FormB(); } // Hide the initial FormA this.Hide(); // Open up the FormB Global.refFormB.Show(); } Where Global class ...Show All

• Visual C++ VS8 resource can't open include

  I am using VS version 8.0.50727.42 (RTM.050727-4200). I converted a VS 2003 project, and I am trying to compile. The project depends on WTL7.1, which I downloaded and set the project compilation paths to point to the appropriate WTL include directory. During compilation I get to a "pddm.rc" file that references a WTL file, like this: #include <atlres.h> When the compiler hits that line, it says: Error 1 fatal error RC1015: cannot open include file 'atlres.h'. However, my project paths are set correctly - and other header files from the same location as atlres.h are found just fine. This problem seems to be unique to an include being processed from within a resource file . Indeed, I've found someone else o ...Show All

• SQL Server Migration of VB Net 2005 (Pro) app using Access 2000 DB (DAO & ADO) to SQL Express

  I've downloaded the migration tool to convert an Access 2000 DB to a SQL DB. The VB code utilizes DAO (3.6) for hourly automatic compaction and the creation of an encrypted security database. ADO is used for the data maintenance functions. I expect the current connection methodology of ODBC using Jet 4.0 will need to be modified (many articles here address this). All the SQL code is inline and also must be modified. The Coldfusion code utilizes Micrsoft Access with Unicode via an ODBC connection with only SQL Select statements. At another job, I migrated an Informix 7 database to MS SQL 7 and for the most part the SQL code remained the same except for the wildcard spec from * to %. I'm looking for insights and/or shortcuts on this effor ...Show All

• Visual Basic Two-pronged Question

  Hi, I'm fairly new to VB and learned on VB 2003. I just upgraded to VBE 2005. I'm trying to make a multiple document reader and modifier. My questions are: 1) To be able to view the most documents, is it better to use a Rich Text Box or something else. 2) Is there any information floating around out there on making document readers I'm trying to be able to read MS Word documents, Works documents, Text files, Rich Text files, and an AutoCAD lisp file(its basically a text file).
