How to run a geoprocessor in ArcGIS?
Create the geoprocessor object. Add the path to the custom toolbox if you are running a custom tool. Create an IVariantArray and populate it with tool parameter values. The IVariantArray is available through the esriSystem library. Call the Execute method on the geoprocessor. The process is the same if you run a system tool or a custom tool.
Do you need to add toolbox to geoprocessor?
As all system toolboxes are readily available to the geoprocessor, you do not need to add the toolbox to the geoprocessor. However, you must add the custom toolbox to the geoprocessor using the AddToolbox method. The only difference between running a system tool and a custom tool is adding the custom toolbox to the geoprocessor.
How are parameters specified in a geoprocessing tool?
Parameters are specified as strings or objects. Strings are text values that uniquely identify a parameter value, such as a path to a dataset or a keyword. Most tool parameters can be specified as a simple string. However, complex parameters, such as a spatial reference, can be easier to specify with an object.
Which is the Execute method of a geoprocessor?
In both cases, the Execute method of the geoprocessor is called. The Execute method uses a null reference instead of an ITrackCancel interface.
How to make geoprocessing layers visible in ArcGIS?
On the ArcMap Options window, click the General tab. On the General panel, check Make newly added layers visible by default if you want layers added by geoprocessing tools to be visible, and uncheck it if you want layers to be non-visible. Feedback on this topic?
How to overwrite the output of geoprocessing operations?
Overwriting tool output. The Overwrite the outputs of geoprocessing operations check box controls whether tools automatically overwrite any existing output when run. When it is checked, you receive a warning before tool execution that the output exists, but the tool executes and overwrites the output dataset.
Where is the background processing panel in ArcGIS?
The Background processing panel is where you control whether a tool executes in foreground or background mode. If Enable is checked, tools execute in the background, and you can continue working with ArcMap (or other ArcGIS applications, such as ArcGlobe) while the tool executes.
How does the Execute method in ArcGIS work?
The Execute method uses a null reference instead of an ITrackCancel interface. The ITrackCancel interface provides access to properties and methods that determine if a cancellation has been executed by the user and also allows developers to specify what actions constitute a cancellation. Both approaches are elaborated with the following examples.
How to run a geoprocessing tool in the background?
Background geoprocessing Starting at ArcGIS 10, background geoprocessing is possible. Using the Geoprocessor.ExecuteAsync method, you can execute a tool or model tool in the background of an ArcGIS application.
How to start geoprocessing with ArcObjects in.net?
An ArcSDE connection, either enterprise or workgroup (optional). Exercise archive gpandnet.zip [ZIP]. This archive contains the source code and the listings in a PDF for easy reference when reading this article and the file geodatabase with the sample data. Why Use the .NET Framework for Geoprocessing?
Why do you need the geoprocessor.net framework?
At ArcGIS 9.2, Esri introduced the Geoprocessor .NET assembly, which opened up the geoprocessing toolbox to .NET developers. There are several reasons you might want to use the .NET Framework for your geoprocessing tasks. Maybe your company’s IT department is already a .NET shop.
