ICLRRuntimeHost::ExecuteApplication Method

Used in manifest-based ClickOnce deployment scenarios to specify the application to be activated in a new domain. For more information about these scenarios, see ClickOnce Security and Deployment.

HRESULT ExecuteApplication(
    [in] LPCWSTR   pwzAppFullName,
    [in] DWORD     dwManifestPaths,
    [in] LPCWSTR   *ppwzManifestPaths,
    [in] DWORD     dwActivationData,
    [in] LPCWSTR   *ppwzActivationData,
    [out] int      *pReturnValue


[in] The full name of the application, as defined for ApplicationIdentity.


[in] The number of strings contained in the ppwzManifestPaths array.


[in] Optional. A string array that contains manifest paths for the application.


[in] The number of strings contained in the ppwzActivationData array.


[in] Optional. A string array that contains the application's activation data, such as the query string portion of the URL for applications deployed over the Web.


[out] The value returned from the entry point of the application.




ExecuteApplication returned successfully.


The common language runtime (CLR) has not been loaded into a process, or the CLR is in a state in which it cannot run managed code or process the call successfully.


The call timed out.


The caller does not own the lock.


An event was canceled while a blocked thread or fiber was waiting on it.


An unknown catastrophic failure occurred. If a method returns E_FAIL, the CLR is no longer usable within the process. Subsequent calls to hosting methods return HOST_E_CLRNOTAVAILABLE.

ExecuteApplication is used to activate ClickOnce applications in a newly created application domain.

The pReturnValue output parameter is set to the value returned by the application. If you supply a value of null for pReturnValue, ExecuteApplication does not fail, but it does not return a value.

Important note Important

Do not call the ICLRRuntimeHost::Start Method method before calling the ExecuteApplication method to activate a manifest-based application. If the Start method is called first, the ExecuteApplication method call will fail.
