I need to use VBA Collection object(that is cliect requirements).But sometimes while getting the items from collection object as " objCollection.Item(ref objclsBOMPresentations)" ,it is giving COMException.So I need to give one if else block to get the type of the item index. As you can see in the code,that is hardcoded.So I am giving try catch exception to make the control go on.Please suggest me how can I implement IF-Else here. object rObj ; object objcls1 = "cls1 "; object objcls2 = "cls2"; VBA.Collection objCollection = (VBA.Collection)myToolFrame.ActiveObjects; try { rObj = objCollection.Item(ref objcls1); m_windowDistributor_ActivateCurrent(ref rObj); } catch (COMException exception) { //Giving exception here if the item is not cls1 type } try { rObj = objCollection.Item(ref objcls2); m_windowDistributor_ActivateCurrent(ref rObj); } catch(COMException exception) { //Giving exception here if the item is not cls2 type } |
