# SOLIDWORKS PDM Professional API Help

# Batch Change States of Files As User Example (C#)

This example shows how to change the states of several files in one batch using other credentials.

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 BatchChangeFileStates_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, and click Add).
// 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 a workflow exists with:
// a. A Waiting for Approval state.
// b. An Approved state.
// c. A Passed Approval transition from the Waiting for Approval state to
// the Approved state.
// d. One or more vault files in the Waiting for Approval state.
// 5. If you want to change states as another user, modify the RunAsUser credentials to match a user in your vault.
// 6. Click Debug > Start Debugging or press F5.
//
// Postconditions:
// 1. The Approve Files dialog box displays.
// a. Select a vault view.
// b. Click Select files to approve.
// c. In the Select File dialog:
// 1. Select vault files in the Waiting for Approval state.
// 2. Click Open.
// d. Click Approve all files.
// 2. Click OK in the Do Transition dialog box.
// The selected files change to the Approved state using the Passed Approval
// transition.
// 3. Close the Approve Files dialog box.
