Cookie specified in ISwAddin::ConnectToSW


Name of the application function used to open the file


File description displayed in the Files of Type menu


File extensions separated by semicolons


Label for your options button or an empty string


Name of the callback method to display your dialog, which appears when a user clicks your options button, or an empty string

Return Value

True if the item was added, false if not


Adds a file type xyz:

Private Function SwAddin_ConnectToSW(ByVal ThisSW As Object, ByVal Cookie As Long) As Boolean


    bWasAdded = pSldWorks.AddFileSaveAsItem2(swCookie, "Test_Callback", "Save As file type", "xyz", 1)


    bWasAdded = pSldWorks.AddFileOpenItem3(swCookie, "Test_Callback", "Open File type", "xyz", "", "")


End Function

Private Function SwAddin_DisconnectFromSW() As Boolean



    bWasItemRemoved = pSldWorks.RemoveFileSaveAsItem2(swCookie, "Test_Callback", "Save As file type", "xyz", 1)

    bWasItemRemoved = pSldWorks.RemoveFileOpenItem2(swCookie, "Test_Callback", "Open File type", "xyz")


End Function


Public Sub Test_CallBack(Filename As String)

    pSldWorks.SendMsgToUser "Callback called with filename = " & Filename End Sub


Adds and removes multiple file types:


bRet = iSwApp.AddFileOpenItem3(addinID, "Test_Callback", "Open My File Type (*.ext1;*.ext2"), "ext1;ext2", "", "")


bRet = iSwApp.RemoveFileOpenItem2(addinID, "Test_Callback", "Open My File Type (*.ext1;*.ext2)", "ext1;ext2")





If your application is unloaded using an add-in, then you must remove any file types added with this method. See ISldWorks::RemoveFileOpenItem2

The callback is called one time if the user:

  • Presses the Shift or Ctrl key and selects multiple files to open in the File Open Dialog.
  • drags-and-drops files into SOLIDWORKS from Windows Explorer or the File Explorer tab in the TaskPane.
