AE development, call to COM component returned error HRESULT E_fail, error in geoprocessing, i.e. GP tool processing

Arcgisengine two times in the development, the geoprocessing, namely: Intersect operation, intersection take counter operation, erase operation and so on, if the permission is improperly assigned, it will appear on the face of COM component call returned error HRESULT e_fail error

The reasons for this are as follows: In the case of Erasure, intersection inversion, and other advanced operations, must be arcgisinfo level of license authorization, otherwise cannot operate, and intersect operation with arcgisengine level. (unstable, error-prone, recommendation 2)

The solution is as follows: 1. Use the Licencecontrol control to select the Arcgisinfo option, and select the spatial analysis

2. Add some code to the project startup Main method

            ESRI. ArcGIS.RuntimeManager.Bind (ESRI. ArcGIS.ProductCode.EngineOrDesktop);            #region Initialize license              iaoinitialize m_aoinitialize = new Aoinitializeclass ();            Esrilicensestatus licensestatus = esrilicensestatus.esrilicenseunavailable;            LicenseStatus = M_aoinitialize.initialize (esrilicenseproductcode.esrilicenseproductcodearcinfo);            if (LicenseStatus = = esrilicensestatus.esrilicensenotinitialized)            {                MessageBox.Show (" No esrilicenseproductcodearcinfo permission! ");                Application.exit ();            }            #endregion

One of the ESRI.ArcGIS.RuntimeManager.Bind (ESRI. ArcGIS.ProductCode.EngineOrDesktop); Two methods are required.

Note: You must have high permissions in front of the authorization, otherwise it will not work, the license to be added from high to low, from high to low sort: esrilicenseproductcodearcinfo, Esrilicenseproductcodearceditor,  Esrilicenseproductcodearcview, Esrilicenseproductcodearcserver, Esrilicenseproductcodeenginegeodb, Esrilicenseproductcodeengine
