Question

I’m rather stuck with a problem I found while attempting to port a package from visual studio 2008 to 2010 and wondered if anyone would have any ideas please note this worked in visual studio 2008 and I am unsure why it doesn’t work in 2010,

the offending piece of code is here:

IVsUIShell uiShell = (IVsUIShell)TestPackage.GetGlobalService(typeof (SVsUIShell));
Guid context =  GuidList.GUIDTestMarkerCmdSet;
                POINTS[] menuPos = new POINTS[1];
                menuPos[0].x = (short)Cursor.Position.X;
                menuPos[0].y = (short)Cursor.Position.Y;
                var hr = uiShell.ShowContextMenu(0, ref context,(int)PkgCmdIDList.ContextMenu, menuPos, this); //access violation happens here.
                if (hr != VSConstants.S_OK)
                    return VSConstants.S_FALSE;
                break; 

uiShell context is a vaild com pointer as far as I can tell and I can call other methods on it without it blowing up.

I think It has to do with the context menu setup in the xml vsct file. relevent parts of which can be seen below.

<Groups>
  <Group guid="guidTestMarkerCmdSet" id="ContextGroup" priority="0x100" >
    <Parent guid="guidTestMarkerCmdSet" id="ContextMenu"/>
  </Group>
</Groups>

<Menus>
  <Menu guid="guidTestMarkerCmdSet" id="ContextMenu" type="Context">
    <Parent guid="guidTestMarkerCmdSet" id="0"/>
    <Strings>
      <ButtonText>Test Runner Context Menu</ButtonText>
      <CommandName>TestRunnerContextMenu</CommandName>
    </Strings>
  </Menu>
</Menus> 

<Buttons>
      <Button guid="guidTestMarkerCmdSet" id="cmdRunTest" priority="0x1" type="Button">
    <Parent guid="guidTestMarkerCmdSet" id="ContextGroup"/>
    <Strings>
      <ButtonText>Run Test</ButtonText>
      <CommandName>cmdRunTest</CommandName>
    </Strings>
  </Button>

  <Button guid="guidTestMarkerCmdSet" id="cmdDebugTest" priority="0x1" type="Button">
    <Parent guid="guidTestMarkerCmdSet" id="ContextGroup"/>
    <Strings>
      <ButtonText>Debug Test</ButtonText>
      <CommandName>cmdDebugTest</CommandName>
    </Strings>
  </Button>

any help would be much appeciated, I’m rather mythed atm

Thank you

This bug was caused by me using an button of type “MenuButton” in the vsct which is now not supported in vs2010.

the workaround is to use a menu inside the group of the context menu instead.
