There are uncommitted transactions. Do you wish to commit these before closing the window?

This happens when ANSI_DEFAULTS is set ON

which enables

SET ANSI_NULLS
SET CURSOR_CLOSE_ON_COMMIT
SET ANSI_NULL_DFLT_ON
SET IMPLICIT_TRANSACTIONS 
SET ANSI_PADDING
SET QUOTED_IDENTIFIER
SET ANSI_WARNINGS

and because of IMPLICIT_TRANSACTIONS transactions that are automatically opened as the result of this setting being ON must be explicitly committed or rolled back by the user at the end of the transaction

so you have to select commit and execute

Controlling order of serialization in asp net c#

use Order with XmlElement

public class ItemGroup
{
    [XmlElement(Order = 0)]
    public Reference Reference { get; set; }
    [XmlElement(Order = 1)]
    public Reference None { get; set; }
    [XmlElement(Order = 2)]
    public Reference Content { get; set; }
    [XmlElement(Order = 3)]
    public Reference Compile { get; set; }
}

The OutputPath property is not set for this project. Please check to make sure that you have specified a valid Configuration/Platform combination

Problem 1

when the OutputPath property of the project file(*.csproj) is blank.

Solution

Provide OutputPath property which normally is \bin\debug or \bin\release

Problem 3

When the OutputPath comes after Import declaration

Solution

Move Imports after all PropertyGroup declarations

A namespace does not directly contain members such as fields or methods

Change the Build Action to None

How to serialize an object to XML without getting xsi and xsd

To remove namespaces all together

just add

var ns = new XmlSerializerNamespaces();
ns.Add("", "");

and then

var xmlSerializer = new XmlSerializer(typeof(Project));

xmlSerializer.Serialize(fs, project, ns);

but if you want to keep xmlns only with xsi and xsd you should add default namespace to XmlSerializer like this

var defaultNamespace = "http://schemas.microsoft.com/developer/msbuild/003";
var xmlSerializer = new XmlSerializer(typeof(Project), defaultNamespace);
 
xmlSerializer.Serialize(fs, project, ns);

Repeat row value in Cross-Tab crystal report

Create a new formula field.
In this formula field, joint all selected column i.e. column1 & column2 & column3. This will create a field which has all distinct values and include this field in your cross tab before the non repeating column.Now all required values will repeat in each row as you like.
