Hello Patterson,
This code is working Perfectly..................But it is displaying the complete path as "F:\PAProject\PAToolbox.tbx\FeatureClassFromXYTable" instead of just toolname "FeatureClassFromXYTable" in the Geoprocessing Pane.
string tool_path = System.IO.Path.Combine(@"F:\PAProject\PAToolbox.tbx", "FeatureClassFromXYTable");
Geoprocessing.OpenToolDialog(tool_path, null);
_________________________________________________________________________________________________
Now When I write the code like this
string tool_path = System.IO.Path.Combine(@"F:\PAProject\PAToolbox.tbx", "FeatureClassFromXYTable");
string tool_path1 =System.IO.Path.GetFileNameWithoutExtension (tool_path);
Geoprocessing.OpenToolDialog(tool_path1, null);
It is showing me just toolname "FeatureClassFromXYTable" in the Geoprocessing Pane. But it is not giving me the required functionality on the click of a button.
