Loading a CAD file

The following sample code demonstrates how to load a CAD file using ImageGear.

C#	Copy Code
using System.IO; using ImageGear.Formats; using ImageGear.Formats.CAD; public static void LoadACadFile(string path) { ImGearCADPage page = null; // Load the file. using (FileStream fileStream = new FileStream(path, FileMode.Open, FileAccess.Read)) { page = (ImGearCADPage)ImGearFileFormats.LoadPage(fileStream); } }

Copy Code

using System.IO;
using ImageGear.Formats;
using ImageGear.Formats.CAD;

public static void LoadACadFile(string path)
{
    ImGearCADPage page = null;

    // Load the file.
    using (FileStream fileStream = new FileStream(path, FileMode.Open, FileAccess.Read))
    {
        page = (ImGearCADPage)ImGearFileFormats.LoadPage(fileStream);
    }
}

VBV.NET	Copy Code
Imports System.IO Imports ImageGear.Formats Imports ImageGear.Formats.CAD Public Sub LoadACadFile(path As String) Dim page As ImGearCADPage ' Load the file. Using fileStream As New FileStream(path, FileMode.Open, FileAccess.Read) page = ImGearFileFormats.LoadPage(fileStream) End Using End Sub

VBV.NET

Copy Code

Imports System.IO
Imports ImageGear.Formats
Imports ImageGear.Formats.CAD

Public Sub LoadACadFile(path As String)
    Dim page As ImGearCADPage

    ' Load the file.
    Using fileStream As New FileStream(path, FileMode.Open, FileAccess.Read)
        page = ImGearFileFormats.LoadPage(fileStream)
    End Using
End Sub

Loading a Password Protected DWG File

Loading a password protected DWG file is similar to loading any other CAD file.

C#	Copy Code
using System.IO; using ImageGear.Formats; using ImageGear.Formats.CAD; public static void LoadAPasswordProtectedDwg(string path, string password) { ImGearCADPage page = null; // Set the password parameter to the password of the file. IImGearFormat format = ImGearFileFormats.Filters.Get(ImGearFormats.DWG); format.Parameters.GetByName("Password").Value = password; // Load the file. using (FileStream fileStream = new FileStream(path, FileMode.Open, FileAccess.Read)) { page = (ImGearCADPage)ImGearFileFormats.LoadPage(fileStream); } }

Copy Code

using System.IO;
using ImageGear.Formats;
using ImageGear.Formats.CAD;

public static void LoadAPasswordProtectedDwg(string path, string password)
{
    ImGearCADPage page = null;

    // Set the password parameter to the password of the file.
    IImGearFormat format = ImGearFileFormats.Filters.Get(ImGearFormats.DWG);
    format.Parameters.GetByName("Password").Value = password;

    // Load the file.
    using (FileStream fileStream = new FileStream(path, FileMode.Open, FileAccess.Read))
    {
        page = (ImGearCADPage)ImGearFileFormats.LoadPage(fileStream);
    }
}

VB.NET	Copy Code
Imports System.IO Imports ImageGear.Formats Imports ImageGear.Formats.CAD Public Sub LoadAPasswordProtectedDwg(path As String, password As String) Dim page As ImGearCADPage ' Set the password parameter to the password of the file. Dim format = ImGearFileFormats.Filters.Get(ImGearFormats.DWG) format.Parameters.GetByName("Password").Value = password ' Load the file. Using fileStream As New FileStream(path, FileMode.Open, FileAccess.Read) page = ImGearFileFormats.LoadPage(fileStream) End Using End Sub

VB.NET

Copy Code

Imports System.IO
Imports ImageGear.Formats
Imports ImageGear.Formats.CAD

Public Sub LoadAPasswordProtectedDwg(path As String, password As String)
    Dim page As ImGearCADPage

    ' Set the password parameter to the password of the file.
    Dim format = ImGearFileFormats.Filters.Get(ImGearFormats.DWG)
    format.Parameters.GetByName("Password").Value = password

    ' Load the file.
    Using fileStream As New FileStream(path, FileMode.Open, FileAccess.Read)
        page = ImGearFileFormats.LoadPage(fileStream)
    End Using
End Sub
