Conversión de código HDD Serial#VB6 en código VB.NET

hard-drive

Question

Tengo un buen pedazo de código tomado de un proyecto de VC ++ que obtiene información completa del disco duro SIN usar WMI (ya que WMI tiene sus propios problemas) Les pido a aquellos de ustedes que se sienten cómodos con las funciones de API que intenten convertir este código VB6 en VB (o C #) .NET y ayuda MUCHAS personas que están en gran necesidad de esta clase de utilidad. Pasé mucho tiempo y busqué en toda la red para encontrar formas de obtener el modelo real y el número de serie de la unidad de disco duro y, finalmente, encontré esta, si solo estuviera en .NET ... Aquí está el código y lo siento por su formateo. problemas, solo péguelo en VB6 IDE:

Answer 1

Eso es mucho código que hay que atravesar para alguien que no entiende el lenguaje hablado utilizado en los comentarios.

Voy a decir esto: en cualquier parte de ese código que vea la palabra clave Type probablemente quiera usar Structure , la sintaxis utilizada para Properties en .Net es un poco diferente, las llamadas a funciones requieren paréntesis, y VB.Net no tiene un '' Any ''type (tal vez System.IntPtr lugar? No estoy seguro).

La mayoría del resto de la sintaxis en VB.Net es la misma y, por lo tanto, es posible que tenga más suerte en solucionar los problemas que ya mencioné y luego abordar cada error (o tipo de error) que obtenga al generar el código resultante individualmente.

Answer 2

Lamento no tener tiempo de convertirlo para usted, pero si a nadie se le ocurre el código, podría hacer algo peor que echar un vistazo a http://www.pinvoke.net . Su código VB6 tiene que llamar a las funciones de la API de Windows para hacer el trabajo, y el código de VB.NET tiene que hacer lo mismo. Llamará a las mismas funciones API.

Por ejemplo, aquí está la página para DeviceIoControl.

Pero si esperas lo suficiente, alguien más podría tener el código a mano :-)

Answer 3

Puede obtener estos datos de WMI. Déjame darte un ejemplo

Answer 4

Sí, conozco VB6, pero el problema está en las declaraciones de función API y los atributos necesarios para pasarles esas estructuras (tipos). ¡Ahí es donde no tengo tiempo para gastar! Si tiene una herramienta automatizada VB6 a VB.NET y VB6 en sí, guarde el código como un proyecto VB6 y convierta el código. No tengo mi VB6.

Answer 5

Try
Dim Searcher_P As New ManagementObjectSearcher("root/CIMV2", "SELECT * FROM Win32_PhysicalMedia")
For Each queryObj As ManagementObject In Searcher_P.Get()
If queryObj("SerialNumber").ToString.Trim = "Y2S0RKFE" Then
Me.Cursor = Cursors.Default
Return True
End If
Next
Catch ex As Exception
MessageBox.Show("An error occurred while querying for WMI data: Win32_PhysicalMedia " & ex.Message)
End Try
Try
Dim Searcher_L As New ManagementObjectSearcher("root/CIMV2", "SELECT * FROM Win32_LogicalDisk WHERE DeviceID = ''C:''")
For Each queryObj As ManagementObject In Searcher_L.Get()
If queryObj("VolumeSerialNumber").ToString.Trim = "226C1A0B" Then
Me.Cursor = Cursors.Default
Return True
End If
Next
Catch ex As Exception
MessageBox.Show("An error occurred while querying for WMI data: VolumeSerialNumber " & ex.Message)
Return False
End Try
