• Windows Forms ListBox drag and drop

  Hi, I'm trying to implement the drag and drop event on a ListBox. What I want to do is to drag an item to another location within the same ListBox and drop it there. I'm wondering if there is a way to display a dotted line at the index the item is dragged into at DragEnter, like many windows applications do. Thanks. If you over-ride DrawItem for the list box you can make the list box items basically look however you want... This should get you started: http://samples.gotdotnet.com/quickstart/howto/doc/WinForms/WinFormsOwnerDrawListBox.aspx HTH ...Show All

• SQL Server SQL Server 2005 Installation Failure on Vista - Hangs at IIS

  I just bought a new laptop with Vista pre-installed and was able to install Visual Studio 2005 Pro, but when attempting to install SQL Server 2005 it just hangs at the IIS detection step. I was using the administrative account. I was able to install the Developer Edition of SQL Server 2000, but I need 2005. Some posts mention IIS version issues and 32 vs 64 bit version issues. Can anyone ellaborate on what is happening and why What is the work around By default, IIS is not turned on in Vista. If you want to install the component Reporting Services (RS) in SQL Server 2005, you need to turn on IIS on Vista first. Please make sure you check IIS Backward Compatibility. Otherwise, you still ca ...Show All

• SQL Server Emailing long messages from SQL2000

  Hello! The problem is this. I have many short messages in a table. I need to tigh them together in one long email message and email to the users. But xp_sendmail is limited to 7,790. How could I send longer messages Or how could I devide the long message and send it in parts (i.e. separate consequtive emails) This doesn't work, it still cuts the messages off at around 7,790: E. Send messages longer than 7,990 characters This example shows how to send a message longer than 7,990 characters. Because message is limited to the length of a varchar (less row overhead, as are all stored procedure parameters), this example writes the long message into a global temporary table consisting of a single text column. The contents of this tem ...Show All

• SQL Server Add connction Fails in VS.NET with SQL Server Everywhere

  When I try to use the "Data Source Configuration Wizard" (Menu: Data\Add New Data Source...) and I try to add a new Connection to the "Northwind.sdf" database using Microsoft SQL Server Mobile Edition it fails with "Unable to find the requested .Net Framework Data Provider.

• Visual Studio Team System Profiling C# Apps on Windows Mobile Devices

  Does the VSTS (Visual Studio Team System) profiling capability allow me to profile apps running on attached mobile devices I need to profile a C# app on an HP iPAQ running Windows Mobile 5.

• Visual Studio 2008 (Pre-release) WCF PeerChannel vs Vista's "People Near Me"

  So I'm sitting at home playing with Vista preRC1 (5536). I notice that "People Near Me" is still there, so I sign in and then go take a look at the API for it. Its completely unmanaged, low-level, Windows API type stuff, but the methods are pretty high level. You can sign in, you can enumerate who is logged into the network, and so on. Windows Meeting Space (Vista) runs on the "People Near Me" (Windows Collaboration API) functionality, and its pretty similar to something I want to accomplish. My question is this: Am I better off using default PNRP on Vista using WCF (what I'm familiar with) , or should I be using the "People Near Me" functionality If the People Near Me functionality is using PNRP, then should ...Show All

• Visual Studio Restrict property value depending on one property

  Hi, I have one Entity with Properties. Each Property has a Type property (which can be numeric, string, boolean, date or memo) and a size property (which is a numeric). The size property is only interesting when type is String. Therefore, I'd like to disable the size property when type is other than string (ideally, it would be great if value is kept, but not shown). Thanks for your help. That seems to work fine. However, I can not change PropertyDescriptor Property Value. It is marked as ReadOnly (for example, the IsReadOnly Property) Did I miss something ...Show All

• SQL Server Error using UnaryOperatorColumn on a Many-to-Many linked dimension
