Una helper class para manejar los servicios de Windows. Por el momento puede listar, iniciar, detener, y determinar el estado o el modo de inicio de un servicio. (no lo he testeado mucho en profundidad) Ejemplos de uso: Dim svcName As String = "themes" Dim svcDisplayName As String = ServiceUtils.GetDisplayName(svcName) Dim svcStatus As ServiceControllerStatus = ServiceUtils.GetStatus(svcName) Dim svcStartMode As ServiceUtils.SvcStartMode = ServiceUtils.GetStartMode(svcName) ServiceUtils.SetStartMode(svcName, ServiceUtils.SvcStartMode.Automatic) ServiceUtils.SetStatus(svcName, ServiceUtils.SvcStatus.Stop, wait:=True, throwOnStatusMissmatch:=True)

Un aspecto para utilizar con la librería Postsharp, para difundir un poquito la programación orientada a aspectos (AOP). Este aspecto en particular sirve para definir un valor mínimo y máximo para un miembro público de una class (Ej: Una propiedad Byte, Short, Integer, Long, etc...), con esto nos aseguramos de que el valor asignado nunca supere el máximo ...ni el mínimo. Hay bastante repetición de código ya que al parecer la Class no se puede hacer genérica. Ejemplo de uso: Imports PostSharp.Aspects Public Class MyClass <RangeAttribute(0S, SByte.MaxValue)> Dim sByteValue As SByte <RangeAttribute(0S, Byte.MaxValue)> Dim ByteValue As Byte <RangeAttribute(0S, Short.MaxValue)> Dim Int16Value As Short <RangeAttribute(0US, UShort.MaxValue)> Dim UInt16Value As UShort <RangeAttribute(0I, Integer.MaxValue)> Dim Int32Value As Integer <RangeAttribute(0UI, UInteger.MaxValue)> Dim UInt32Value As UInteger <RangeAttribute(0L, Long.MaxValue)> Dim Int64Value As Long <RangeAttribute(0UL, ULong.MaxValue)> Dim UInt64Value As ULong <RangeAttribute(0.0F, Single.MaxValue)> Dim SglValue As Single <RangeAttribute(0.0R, Double.MaxValue)> Dim DblValue As Double End Class

Comparto este snippet para compilar código fuente en tiempo de ejecución, una DLL, una app CLI o GUI, desde un string o desde un archivo que contenga el código guente. Es útil por ejemplo para bindear archivos, o embedir tablas de recursos en una dll, o simplemente para compilar un código de C# o VB.Net. Ejemplo de uso: Using vbCodeProvider As New Microsoft.VisualBasic.VBCodeProvider Dim resultVB As CompilerResults = CodeDomUtil.CompileAssembly(codeProvider:=vbCodeProvider, targetAssembly:=CodeDomUtil.TargetAssembly.Dll, targetFile:="C:\VB Assembly.dll", resources:={"C:\MyResources.resx"}, referencedAssemblies:={"System.dll"}, mainClassName:="MainNamespace.MainClass", sourceCode:=<a> Imports System Namespace MainNamespace Public NotInheritable MainClass End Class End Namespace </a>.Value) Dim warnings As IEnumerable(Of CompilerError) = From ce As CompilerError In resultVB.Errors.Cast(Of CompilerError)() Where ce.IsWarning Dim errors As IEnumerable(Of CompilerError) = From ce As CompilerError In resultVB.Errors.Cast(Of CompilerError)() Where Not ce.IsWarning For Each war As CompilerError In warnings Debug. WriteLine(String. Format("{0}| Warning: {1}", war. ErrorNumber, war. ErrorText)) Next war For Each err As CompilerError In errors Debug. WriteLine(String. Format("{0}| Error: {1}", err. ErrorNumber, err. ErrorText)) End Using

¿Habeis sentido alguna vez la necesidad de mover una o varias filas de un DataGridView preservando el valor de algunas celdas en el transcurso?, pues yo si, así que comparto este código rehusable que me parece bastante sofisticado para llevar a cabo esa tarea, soporta multi-selección de filas, pero es para manipular directamente las filas de un DataGridViev, no el datasource. Ejemplo de uso: Me.DataGridView1.MoveSelectedRows(DataGridViewMoveRowDirection.Up)
Me.DataGridView1.MoveSelectedRows(DataGridViewMoveRowDirection.Up, {0, 2})

Hola Eleкtro.
Disculpas las molestias pero el primer link de la pag 1 de snippets que es de mediafire no funciona ni tampoco el de la pagina 36 Actualizada la colección de snippets con un total de 544 Snippets talvez puedas compartirlos en otro compila o volver a subir ese no habia teniado el gusto de ver el tema y me parece muy bueno.
Saludos.

Hmmm... antes de nada, ¡Gracias por avisar!, pero estoy preparando una actualización importante, hay muchos snippets antiguos que necesitan una refactorización completa, otros es mejor eliminarlos o adaptarlos para otros propósitos, y en fin, un lio, prefiero no resubir nada de momento hasta que no "limpie" todos los snippets, y son unos 700 (me está llevando meses xD). De todas formas, aquí puedes descargar una versión más reciente de la colección de snippets: (si prefieres no usar el exe, puedes desempaquetar su contenido con la aplicación InnoUnp para InnoSetup) Saludos!
