[solved] RibbonSample vb.net not working in VS2017

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I try to run a sample for the ribbon found in:C:\Program Files (x86)\Codejock Software\ActiveX\Xtreme SuitePro ActiveX v18.3.0\Samples\CommandBars\VB.NET\RibbonSample

When I hit run, i get the following error:

	System.NullReferenceException: 'Object reference not set to an instance of an object.'

found at:

    Private Sub CommandBars_ResizeClient(ByVal sender As Object, ByVal e As 	AxXtremeCommandBars._DCommandBarsEvents_ResizeClientEvent) Handles 	CommandBars.ResizeClient
        Refresh()
    End Sub

among other "Exception thrown: 'System.NullReferenceException' in RibbonSample.exe"

It must be something very obvious, but I cannot get it to work. It migrated from a previous version, but I don't think this is the issue. Any ideas?

	Hello, Make sure older versions of SuitePro uninstalled and unregistered properly. Also try to change in Configuration Manager Platform from "Any CPU"/"x64" to x86 then rebuild solution. Regards, Oleksandr Lebed

	Thank you for your reply, I did all that but the problem remains. Actually, the program crashes alltogether when I run it ("RibbonSample has stopped working"), and I cannot find the point where it crashes to put a breakpoint. It seems this happens when the window tries to paint the Ribbon. EDIT: After modifying a RibbonSample a lot, and randomly playing around with configurations, I found that commenting out the following snippet in the CreateRibbonBar() method allows the program to start, although the ribbon is probably not drawn properly: 'this crashes 'ControlFile = RibbonBar.AddSystemButton() 'ControlFile.IconId = ID_SYSTEM_ICON 'ControlFile.Caption = "&File" 'ControlFile.Style = XtremeCommandBars.XTPButtonStyle.xtpButtonCaption 'CreateBackstageView()

	I get the following error: System.Runtime.InteropServices.COMException: 'Class is not licensed for use (Exception from HRESULT: 0x80040112)' at frmMain.cs private void CommandBars_ResizeClient(object sender, AxXtremeCommandBars._DCommandBarsEvents_ResizeClientEvent e) { Refresh(); <<<<<<here } I have installed the whole bundle normally, and I have worked with other controls such as chart, datepicker, etc without any problems.

	I am aware that there are no similar problems in the forum, which probably means that it is something stupid on my part. I have just found that running the sample in situ (C:\Program Files (x86)\Codejock Software\ActiveX\Xtreme SuitePro ActiveX v18.3.0\Samples\CommandBars\VB.NET\RibbonSample) works OK!!! But if I copy the whole RibbonSample folder in a temp folder (which I have done so far for backup reasons - it migrates from a previous version), the project compiles successfully but doesn't work as described earlier. Is this any help?

	I have found reason. System.NullReferenceException is about missing theme DLL. They allocated in c:\Program Files (x86)\Codejock Software\ActiveX\Xtreme SuitePro ActiveX v18.3.0\Samples\Styles\ you can just change method StylesPath() in frmMain.vb to get correct path and copy that DLLs to correct path.
