• Visual C# C# - Namespaces - accessing of sub-namespaces

  Consider the following code snippet, in a file: namespace NamespaceA.NamespaceB.NamespaceC { public class ClassC { public static string StringC { get { return "string c" ; } } } } Now, I want to be able to access the property from within another file. The following works - using NamespaceA.NamespaceB; namespace Tester { public class TesterClass { public string StringC() { string myValue; myValue = NamespaceA.NamespaceB .NamespaceC. ClassC .StringC; return myValue; } } } However, I don't want to have to explicitly use NamespaceA ...Show All

• .NET Development Discovering named instances

  Given: VB.net .Net Framework 1.1 In my program I use ODBC:SQLDataSources to discover available SQL Servers. I have recently realized that my code does not discover the Named Instance of SQL2005 which runs along side SQL2000 on my machine. I believe that .Net Framework 2.0 has a new function for SQL Server enumeration but I need to remain at the 1.1 level for some time. Is there a better way to discover SQL Servers which will discover the Named Instances in addition to the defauls instances Thanks Mr. Vaughn. Unless I'm missing somethign I believe the technique you show uses a function available on ...Show All

• Visual Studio Express Editions Problem with maskedtextbox validation and keypress

  Hi, I have a problem with masked textboxes. I'm really getting annoyed with this one and can't find any more a solution. I have a form where you enter inputs and there inputs are recorded to the db. I have a maskedtextbox which is optional. But I want that if someone writes something in it, it checks validation and if it's not valid, it's lbl will become red to indicate user to enter a valid data. Maybe I have a logic or syntax error but other maskedtextboxes validatetext method works!! I have used If cellphone.Text <> Nothing And cellphone.ValidateText = False   Then lbl_cell.ForeColor = Color.Red El ...Show All

• Smart Device Development termination

  I'm developing an application with several modeless forms. The project starts in SUB MAIN which calls the first form. Each form closes itself and starts the next form. All that works except I can't get the application to terminate properly. Is there a single call I can use from within the last form to execute that terminates the application Is there any other way I can do it Thanks for the speedy reply. application.exit() just puts the application in a suspended state. Then when you try to restart it nothing visible happens. The exe file on the PDA is also busy so you can't overwrite it with a new versi ...Show All

• SQL Server Import variable fixed length file

  I have a requirement to import a file of rows containing fixed length data. The problem is that each row can be one of 5 different formats (i.e. different columns) -- where the "type" of row is indicated by the first two characters of the row. Each row gets inserted into its own table. Could I use a simple Conditional Split to route the rows Or is the split for routing similiar rows Anyways, problems are never this simple... In addition, each "grouping" of rows is related. The "first" row is considered the "primary" row (and gets a row id via IDENTITY, whereas the remaining rows in the group are ...Show All

• SQL Server Possible bug with SqlServer 2005 calling UDT Read method?

  Hi, I have a UDT written in C# that is formatted with UserDefined. I added the IBinarySerialize interface and it was implemented automatically by Visual Studio as follows: void IBinarySerialize .Read(System.IO. BinaryReader r) void IBinarySerialize .Write(System.IO. BinaryWriter w)   This compiles fine, and the assembly deploys fine. However, when I execute a call to a stored procedure and pass a UDT that has these methods implemented, I get a message saying: System.Data.SqlClient.SqlException: Could not find method 'Read' for type 'Test.Seller' in assembly 'TestUDT' So it appears that the deserialization ...Show All
