abstract GetProjectDependencies : 
        pHier:IVsHierarchy * 
        celt:uint32 *

function GetProjectDependencies(
    pHier : IVsHierarchy, 
    celt : uint, 
    rgpHier : IVsHierarchy[], 
    pcActual : uint[]
) : int

Parameters

pHier
Type: Microsoft.VisualStudio.Shell.Interop.IVsHierarchy

[in] Pointer to an IVsHierarchy object.

celt
Type: UInt32

[in] Specifies celt.

rgpHier
Type: array<Microsoft.VisualStudio.Shell.Interop.IVsHierarchy[]

[in, out] Specifies projects to build.

pcActual
Type: array<UInt32[]

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

Return Value

Type: Int32
If the method succeeds, it returns S_OK. If it fails, it returns an error code.

Remarks

COM Signature

From vsshell.idl:

HRESULT IVsSolutionBuildManager2::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 = nulla null reference (Nothing in Visual Basic), 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 = pIVsSolutionBuildManager2->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 = pIVsSolutionBuildManager2->GetProjectDependencies(pHier, ulActual, rgpIVsHierarchy, &ulActual2);

// use the pointers here

// release the hier pointers

// release the memory

::CoTaskMemFree(rgpIVsHierarchy);
