.NET Forum / Visual Studio.NET / Extensibility / September 2005How can I execute Edit.GoToDefinition and check return status?
Hi, I'm writing some functionality that first requires jumping to the definition of the symbol under the cursor. Is it possible to somehow call Edit.GoToDefinition and check its return status so that I know if the symbol definition was found or not? I thought of checking the cursor position before and after executing the command; if they're the same then it's likely the command failed, but I still get the message box. Is there some alternate way to find the definition of a symbol programmatically? Thanks. Hi Parag, >Is it possible to somehow call Edit.GoToDefinition and check >its return status so that I know if the symbol definition was found >or not. >...... In the VS IDE's code editor, If the selected text/symbol doesn't not have a definition, then the GoToDefinition command in the UI will be disabled. This status is checked by the IVsObjectList.CanGoToSource method, I suggest you could take a look on it. Thanks!

Hi Gary, I didn't have a chance to try this out earlier, so I want to revisit it now. How do I obtain an IVsObjectList? It seems like I might be able to make use of SVsObjectManager to call IVsObjectManager2.GetListAndIndex(), but it's not clear what I should pass in for pNavInfo or dwFlags. Do you have some client code obtaining and making use of IVsObjectList? Thanks. > Hi Parag, > [quoted text clipped - 24 lines] > This posting is provided "AS IS" with no warranties, and confers no > rights. Hi Parag, Currently, we are looking into this problem.

Hi Param, I need to confirm do you want to implement the IVsObjectLists yourself or you are trying to access the lists implemented by some other symbol provider? Thanks!

Hi Gary, I want to access the IVsObjectLists of some other provider; no interest in implementing my own just yet.

Hi Parag, >I want to access the IVsObjectLists of some other >provider; no interest in implementing my own just yet. OK, if so, I suggest you try the IVsLibrary2::CreateNavInfo at first. You can pass a description of the element you are interested and you get a NavInfo object back. The array of SYMBOL_DESCRIPTION_NODE will be a list like: mscorlib LLT_PHYSICALCONTAINERS System LLT_NAMESPACES Boolean LLT_CLASSES Then you will get this info from current selection or similar. You may use IVsNavigationTool::GetSelectecSymbols. From IVsSelectedSymbol you can call GetNavInfo to get a NavInfo directly. To obtain the IVsLibrary2 object, please refer to the IVsObjectManager2::FindLibrary, where you pass a GUID to the library you are interested. You can obtain the guid from a NavInfo by calling IVsNavInfo::GetLibGuid. Wish this helps!
