VBA-API change active sheet

[mvitárius]

 Hello.

I would like to change the active sheet on a drawing using VBA-API, but I can't find any way to do it, I'm new to VBA-API. The best I cold manage was to use macro to change sheets, which worked, but did produce somr undesired effect.

The documentation states "You can regenerate a sheet only if it is displayed.", so it must be possible to change  the displayed sheet.

My code so far

Public Sub change_sheet_parameter()
     
        Dim conn As IpfcAsyncConnection
        Dim cAC As CCpfcAsyncConnection
        Dim session As IpfcBaseSession
        Dim model1 As IpfcModel
        Dim sheetData As IpfcSheetData
        Dim sheetowner As IpfcSheetOwner
        Dim sheetInfo As IpfcSheetInfo


Set cAC = New CCpfcAsyncConnection
Set conn = cAC.Connect("", "", ".", 5)

Set session = conn.session



Dim oModelDescriptorCreate As New CCpfcModelDescriptor
Dim oModelDescriptor As IpfcModelDescriptor

name_w = "SHM-7457-004.drw" 'Name of the drawing

 Set oModelDescriptor = oModelDescriptorCreate.Create(EpfcMDL_DRAWING, name_w, Null)
 Set model1 = session.RetrieveModel(oModelDescriptor)
 Set sheetowner = model1

    Dim oWindow As pfcls.IpfcWindow
    Set oWindow = session.OpenFile(oModelDescriptor)

    oWindow.Activate


Set sheetInfo = sheetowner.GetSheetInfo(1)
test_ = sheetInfo.Height
MsgBox test_

'The part where I would like to change the displayed sheet.

sheetowner.RegenerateSheet (1)

End Sub

So the answer was in the tutorials for VBAPI in the pfcDrawingExample.vb

In the "Create drawing views" example it clearly shows what command to use.

    'Create drawing views
