Problem using Legends

[bhopaltechie]

I am facing a problem using Legends; When I drop legends manually the legends get updated on each drop of shape, whereas when I drop it by writing suitable code the legend drops, but doesn't get updated. When after dropping it programmatically, I manually open the Visio document and click Configure Legends, the Legend gets updated. Please let know what is the problem and how to refresh/ update legend.

Thanks and Regards

I tried dropping the legend shape and then running the addon using following code in C++:-

_variant_t name;
name.vt=VT_BSTR;
_bstr_t legend = "lgnd";
name.bstrVal= legend;
IVAddonsPtr addsPtr;
app->get_Addons(&addsPtr);
IVAddonPtr addptr;
addsPtr->get_Item(name,&addptr);
_bstr_t runString = "/cmd=cmd2";
addptr->Run(runString);

Still no use.
