ICLRRuntimeHost::ExecuteApplication Method
Used in manifest-based ClickOnce Deployment scenarios to specify the application to be activated in a new domain.
HRESULT ExecuteApplication(
[in] LPCWSTR pwzAppFullName,
[in] DWORD dwManifestPaths,
[in] LPCWSTR *ppwzManifestPaths,
[in] DWORD dwActivationData,
[in] LPCWSTR *ppwzActivationData,
[out] int *pReturnValue
);
Parameters
- pwzAppFullName
[in] The full name of the application, as defined for ApplicationIdentity.
- dwManifestPaths
[in] The number of strings contained in the ppwzManifestPaths array.
- ppwzManifestPaths
[in] Optional. A string array that contains manifest paths for the application.
- dwActivationData
[in] The number of strings contained in the ppwzActivationData array.
- ppwzActivationData
[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.
- pReturnValue
[out] The value returned from the entry point of the application.
Return Value
| HRESULT | Description |
|---|---|
S_OK |
ExecuteApplication returned successfully. |
HOST_E_CLRNOTAVAILABLE |
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. |
HOST_E_TIMEOUT |
The call timed out. |
HOST_E_NOT_OWNER |
The caller does not own the lock. |
HOST_E_ABANDONED |
An event was canceled while a blocked thread or fiber was waiting on it. |
E_FAIL |
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. |
Remarks
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
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.
