• SQL Server Smart App to Endpoint Kerberos Authentication

  We have a smart app client application that leverages SQL Server Endpoints for data access. Clients use this application from several cities in the US across a corporate WAN. The endpoint is secured using kerberos authentication. Users of the application are added to a domain group which is granted rights to the endpoint. Procedures in the database are granted to a SQL role, and the domain group has been added to the database as a login and added to the role. Everything works fine for users in the home city where the data center resides. The problem is that when users from a remote office try an connect up, there is anywhere from a 15 ...Show All

• .NET Development ADO.NET DataTable as OLE DB Provider??

  As abnormal of a usage this may seem...

• Visual C# Trees

  I am trying to use C# for my program that deals with manipulation of trees (i.e. finding distance between different nodes, assigning labels to nodes, storing trees, etc.). I know I can probably use a multi-dimensional array as my data structure. However, I wanted to find out if C# had any built-in APIs for trees. Thanks in advance. Hi, This may not exactly what you need, but you can reuse the TreeNode object as you handle your Tree, instead of manually handling multi-dimensional array. TreeNode object can be used as your storage, but you still have to manually perform the search operations, labeling, ...Show All

• SQL Server Backup of databases within SQL Server 2005 Express

  Hi there! Is there any replacement for the missing SQL Server Agent which could be configured to backup "all databases" and fix minor errors in databases, rebuild indexes, etc. Or let's better ask: is there any solution/tool out there to create and execute maintenance plans without the need of SQL Server Agent (It might be a simple tool that enumerates the DBs and executes some T-SQL statements on them) Thanks Jochen Management Studio Express provides UI to do those things, but there is no Agent in SQL Server Express, so the tasks can only be executed once in the UI. Instead, you could use the UI to create t ...Show All

• .NET Development Problem with reflecting types in an assembly

  I have run into a problem with trying to determine whether a type implements a given interface. Everything I have tried does not work. What I am attempting to do is: 1. load an assembly (using assembly.LoadFrom() ) 2. Iterate over all the types in the assembly (types are retrieved using assembly.GetTypes() ) 3. If the type implements a given interface then add it to a list My problem occurs on step 3. I have tried using 1. "TypeOf iteratedType is MyInterface" 2. iteratedType.IsAssignableFrom 3. iteratedType.IsSubClassOf 4. iteratedType.GetInterface("MyInterface") None of these methods are working. When I use R ...Show All

• Windows Forms How to put Radio Buttons in a Menu

  I am building a standard desktop application with a menu bar on top. One of the drop down menu's I want to fill with Radio Buttons. Here is a description of Radio Buttons by Petzold, in Programming Windows 95: <quote> Radio Buttons A radio button looks very much like a check box except that it is shaped like a circle rather than a box. A heavy dot within the circle indicates that the radio button has been checked (...). Groups of radio buttons are conventionally used to indicate mutually exclusive options. Unlike check boxes, radio buttons do not work as toggles - that is, when you click a radio butt ...Show All

• Windows Forms Project resources duplicated to local form resources

  Scenario: I want to add an image to a button on a win form. This image is already a project resource (in the resources tab of the project properties). In the 'Select Resource' dialog for the button's 'Image' property, I select 'Project resource file' and select the image. After saving the form and reloading it, this dialog has changed to 'Local resource' and the image has been copied to the form's .resx file. Can anyone else replicate this If so, why can't the button's image property just point to the project resource ...Show All

• .NET Development Portable Executable(PE) in applications not-managed

  is there a way to reference a Portable executable library(dll of .net) in a delphi 5 application, for example thanks Hi Edwin Santos, It is possible to consume .NET based DLLs making use of COM Interop. You would need to register the DLL for COM Interop using the tool RegAsm. Once registered the .NET DLL also would have a ProgId similar to COM DLLs. Now, since Delphi understands COM, you can instantiate this object using the CreateOleObject method of Delphi from the ComObj Unit. Regards, Vikram ...Show All

• Visual C# Unable to load class library
