IVsProject4.GetFilesWithItemType(String, UInt32, UInt32[], UInt32) Method

Definition

Returns an array of VSITEMIDs of files whose MSBuild ItemType matches the given string. The comparison is case insensitive.

public:
 int GetFilesWithItemType(System::String ^ pszItemType, System::UInt32 celt, cli::array <System::UInt32> ^ rgItemids, [Runtime::InteropServices::Out] System::UInt32 % pcActual);
int GetFilesWithItemType(std::wstring const & pszItemType, unsigned int celt, std::Array <unsigned int> const & rgItemids, [Runtime::InteropServices::Out] unsigned int & pcActual);
public int GetFilesWithItemType (string pszItemType, uint celt, uint[] rgItemids, out uint pcActual);
abstract member GetFilesWithItemType : string * uint32 * uint32[] * uint32 -> int
Public Function GetFilesWithItemType (pszItemType As String, celt As UInteger, rgItemids As UInteger(), ByRef pcActual As UInteger) As Integer

Parameters

pszItemType
String

The ItemType.

celt
UInt32

The number of files to return.

rgItemids
UInt32[]

The array of ITEMIDs.

pcActual
UInt32

The actual number of files returned.

Returns

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

Examples

An extremely common pattern is to call the method twice, the first time passing in 0 for the number of items and NULL for the array, and the second time passing in a properly-sized array and the actual number of items, and like the following (omitting error checks for readability):

hr = pIVsProject4->GetFilesWithItemType(szItemType, 0, NULL, &cExpected);  
VSITEMID *rgItemids = ::CoTaskMemAlloc(cExpected * sizeof(VSITEMID));  
hr = pIVsProject4->GetFilesWithItemType(szItemType, cExpected, rgItemids, &cActual);  

Remarks

If celt is zero and rgItemids is NULL, the number of matching files is returned in pcActual. If celt is not zero, rgItemids must not be NULL, or E_POINTER is returned.
