Batch Change States of Files Example (VB.NET)
This example shows how to change the states of several
files in one batch.
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 2010.
' a. Click File > New > Project > Visual Basic > Windows Forms Application.
' b. Type BatchChangeFileStates 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.vb in the Solution Explorer.
' f. Replace the code in Form1.vb with this code.
' g. To create the
form, replace the code in Form1.Designer.vb 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 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. Modify the bsPasswd parameter in IEdmBatchChangeState4::ChangeState2 to
' match the password of your logged-in PDM user.
' 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.
