Definition

Namespace:

Microsoft.VisualStudio.Shell.Interop

Assembly:

Microsoft.VisualStudio.Interop.dll

Package:

Microsoft.VisualStudio.Interop v17.12.40391

Returns a list of projects that the given hierarchy depends on.

int GetProjectDependencies(Microsoft::VisualStudio::Shell::Interop::IVsHierarchy const & pHier, unsigned int celt, std::Array <Microsoft::VisualStudio::Shell::Interop::IVsHierarchy const &> const & rgpHier, std::Array <unsigned int> const & pcActual);

public int GetProjectDependencies (Microsoft.VisualStudio.Shell.Interop.IVsHierarchy pHier, uint celt, Microsoft.VisualStudio.Shell.Interop.IVsHierarchy[] rgpHier, uint[] pcActual);

abstract member GetProjectDependencies : Microsoft.VisualStudio.Shell.Interop.IVsHierarchy * uint32 * Microsoft.VisualStudio.Shell.Interop.IVsHierarchy[] * uint32[] -> int

Public Function GetProjectDependencies (pHier As IVsHierarchy, celt As UInteger, rgpHier As IVsHierarchy(), Optional pcActual As UInteger()) As Integer

Parameters

pHier

IVsHierarchy

[in] Pointer to an IVsHierarchy object.

celt

UInt32

[in] Specifies celt.

rgpHier

IVsHierarchy[]

[in, out] Specifies projects to build.

pcActual

UInt32[]

[out, optional] Pointer to the number of projects.

Returns

Int32

If the method succeeds, it returns S_OK. If it fails, it returns an error code.

Remarks

COM Signature

From vsshell.idl:

HRESULT IVsSolutionBuildManager::GetProjectDependencies(  
   [in] IVsHierarchy *pHier,  
   [in] ULONG celt,  
   [in, out, size_is(celt)] IVsHierarchy *rgpHier[],  
   [out, optional] ULONG *pcActual  
);  

Returns a list of projects that the given hierarchy depends on.

You should call CalculateProjectDependencies prior to calling GetProjectDependencies if you are unsure if the dependencies are up to date at the point of the call. CalculateProjectDependencies will force project dependencies to be recalculated.

This method should be called twice, the first time with celt = 0 and rgpHier = null, to get the size in pcActual, then a second time after allocating the list to get the projects.

The method will be implemented as follows (error checks are omitted):

ULONG ulActual;

hr = pIVsSolutionBuildManager->GetProjectDependencies(pHier, 0, NULL, &ulActual)

// allocate memory to hold the hierarchy pointers

IVsHierarchy** rgpIVsHierarchy = (IVsHierarchy**) ::CoTaskMemAlloc(ulActual * sizeof(IVsHierarchy *));

memset(rgpIVsHierarchy, 0, sizeof(IVsHierarchy*)*ulActual);

// now get the hierarchy pointers

ULONG ulActual2;

hr = pIVsSolutionBuildManager->GetProjectDependencies(pHier, ulActual, rgpIVsHierarchy, &ulActual2);

// use the pointers here

// release the hier pointers

// release the memory

::CoTaskMemFree(rgpIVsHierarchy);
