Create a Display Flow Arrows Addin

ArcMAP ESRI Add-in for Display flow arrows for Utility Geometric Network

Software Required:

Microsoft Visual Studio 2010 +

ArcMap 10.2 or more

ArcObjects SDK for .Net Installed

Procedure:

• Open Visual Studio 2010
• Create a New Project > Visual C#> ArcGIS>Desktop Addins >ArcMap Add In
• ArcMap Addin Wizard will appear on the Screen.Give a desired name for your Addin and click Next
• In the Addin Types Enable Button checkbox and provide description for it.This will appear as a button tooltip in your ArcMap application.Click finish to end the wizard.
• Now go the Solution Explorer(View>Soln Explorer) and open the Addinname.cs file if it doesn't appear in your screen.
• Replace the content of the file with the following data.
• Add the References(Right click references in Solution Explorer and select Add References) based on your classes usage

//Add the references in to the current namespace

• Save your Current project .Don't run your Code.
• Go to Properties>Addinname Properties>Debug option.Set your ArcMap as the External program for debugging the code
• Run the Code.
• ArcMap Application will open.Now go to Customize>Customize mode>Command.Right now you will see your Addin name in the category list click on it.After that the button will get displayed on the commands window.
• Drag the Button and put it in the Menu bar.
• You get the ESRI Addin file bin>Debug folder of your project location
• Now its party time :) Share your work with other through the Addin file
