Visual Basic (Declaration)
Function IsPackageInstalled ( _
ByRef guidPackage As Guid, _
<OutAttribute> ByRef pfInstalled As Integer _
) As Integer
Dim instance As IVsShell
Dim guidPackage As Guid
Dim pfInstalled As Integer
Dim returnValue As Integer
returnValue = instance.IsPackageInstalled(guidPackage, _
pfInstalled)
int IsPackageInstalled(
ref Guid guidPackage,
out int pfInstalled
)
int IsPackageInstalled(
[InAttribute] Guid% guidPackage,
[OutAttribute] int% pfInstalled
)
function IsPackageInstalled(
guidPackage : Guid,
pfInstalled : int
) : int
Parameters
- guidPackage
- Type: System..::.Guid%
[in] Unique identifier of the VSPackage.
- pfInstalled
- Type: System..::.Int32%
[out, retval] true if the VSPackage is installed in the registry.
Return Value
Type:
System..::.Int32
If the method succeeds, it returns S_OK. If it fails, it returns an error code.
COM Signature
From vsshell.idl:
HRESULT IVsShell::IsPackageInstalled(
[in] REFGUID guidPackage,
[out, retval] BOOL *pfInstalled
);
This method can be used to achieve advanced interactions between multiple VSPackages to determine whether they are loaded. It is recommended that you query for services that other VSPackages proffer.
