Get Preview Bitmap of File Example (C#)

This example shows how to get the preview bitmap of a file.

NOTE: If using the primary interop assembly provided with SOLIDWORKS PDM Professional, see Using .NET Framework 4.0 in Stand-alone Applications.

//----------------------------------------------------------------------------
// Preconditions:
// 1. Start Microsoft Visual Studio.
//    a. Click File > New > Project > Visual C# > Windows Forms Application.
//    b. Type GetPreviewBitmap_CSharp in Name.
//    c. Click Browse and navigate to the folder where to create the project.
//    d. Click OK.
//    e. Click Show All Files in the Solution Explorer toolbar and expand
//       Form1.cs in the Solution Explorer.
//    f. Replace the code in Form1.cs with this code.
//    g. To create the form, replace the code in Form1.Designer.cs with
//       this code.
// 2. Add EPDM.Interop.epdm.dll as a reference (right-
click the project
//    name in the Solution Explorer, click Add Reference, click
//    Assemblies > Framework in the left-side panel, browse to the top folder of
//    your SOLIDWORKS PDM Professional installation, locate and click
//    EPDM.Interop.epdm.dll, click Open, click Add, and click Close).
// 3. Right-click EPDM.Interop.epdm in References, click Properties, and set
//    Embed Interop Types to False to handle methods that pass arrays of
//    structures.
// 4.
Ensure that the root folder of the vault contains an Autodesk DWG file.
// 5. Click Debug > Start Debugging or press F5.
//
// Postconditions:
//  1. Displays the Get Preview Bitmap dialog box.
//     a. Select a vault view.
//     b. Click Select file.
//     c. In the Select File dialog:
//        1. Click a DWG file inside the vault.
//        2. Click Open.
