    I have created quite a few AutoCAD commands, but I think it’s a troublesome thing let users remember the shortcuts, I want to create a toolbar for these commands through C# code, I hope someone can provide a simple and detailed tutorial, step by step is the best..

Sincerely thank

Toolbars are a big topic. Took me weeks of search and testing to get the following code down. Make of it what you will. Sorry but I'm not explaining it line by line. I encourage you to search the forums, the dev blog and the Through the Interface blog as well.

P.S. the .bmp's are project resourses.


public void RLCui()
      //Coded by: Lev Villanueva (doucedeux@gm**l.com)
      Document newDocument = Application.DocumentManager.MdiActiveDocument;
      Database newDatabase = newDocument.Database;

      bool exists = false;
      String mainCUI = Application.GetSystemVariable("MENUNAME").ToString() + ".cuix";      
      CustomizationSection mainCS = new CustomizationSection(mainCUI, false);
      String baseFolder = mainCUI.Replace(mainCS.CUIFileBaseName + ".cuix", "");
      PartialCuiFileCollection newPCFC = mainCS.PartialCuiFiles;
      String cuiFileToSend = "\"" + baseFolder + "RL.cuix" + "\"";
      String test1 = mainCUI.Replace(mainCS.CUIFileBaseName + ".cuix", "RL.cuix");
      if (newPCFC.Contains(mainCUI.Replace(mainCS.CUIFileBaseName + ".cuix", "RL.cuix")))

Re: Create Toolbar with C#

12-28-2013 09:07 AM in reply to: joantopo

   I don’t want a Docking Palette, just Toolbar

   For example, draw a line, there is sample code, so I study it will be very convenient
   There also should be sample code for how to creat a very simple Toolbar, and have a button, and the button can execute a esay function, just like output a string.
   I hope to find a such sample code, then I can start easily

   Sincerely thanks

Any reason why not creating a Ribbon Panel?
The Toolbar technology is a relic from the old days.
You find more samples creating Ribbon style menu's.

Just create a partial CUI and create your commands then you can just drag them on Ribbon Panels, Menus, Toolbars, etc.......

Re: Create Toolbar with C#

12-31-2013 06:48 AM in reply to: jeff

   I hope interface and functionality together, but as I demonstrate below, I only know a way to separate treatment. I want to some friends can help me


   Achieve functional

   Below is a very simple command written in C #, Just only need be compiled into dll file, and then enter NETLOAD load the dll file from AutoCAD, and enter HW from a command prompt, it will output “Hello World”


using Autodesk.AutoCAD.ApplicationServices;
using Autodesk.AutoCAD.DatabaseServices;
using Autodesk.AutoCAD.Runtime;
[assembly: CommandClass(typeof(MyNameSpace.HelloWorld))]
namespace MyNameSpace
class HelloWorld
        public void hello()
            Document acDoc = Application.DocumentManager.MdiActiveDocument;
            Database acCurDb = acDoc.Database;
            acDoc.Editor.WriteMessage("\nHello World");


   Automatically loaded

   Below method copy from AutoCAD. NET Developer's Guide directly,It let the program to get automatic loading function

public void RegisterMyApp()
  string sProdKey = HostApplicationServices.Current.RegistryProductRootKey;
  string sAppName = "MyApp";
  RegistryKey regAcadProdKey = Registry.CurrentUser.OpenSubKey(sProdKey);
  RegistryKey regAcadAppKey = regAcadProdKey.OpenSubKey("Applications", true);
  string[] subKeys = regAcadAppKey.GetSubKeyNames();
  foreach (string subKey in subKeys)
      if (subKey.Equals(sAppName))
  string sAssemblyPath = Assembly.GetExecutingAssembly().Location;
  RegistryKey regAppAddInKey = regAcadAppKey.CreateSubKey(sAppName);
  regAppAddInKey.SetValue("DESCRIPTION", sAppName, RegistryValueKind.String);
  regAppAddInKey.SetValue("LOADCTRLS", 14, RegistryValueKind.DWord);
  regAppAddInKey.SetValue("LOADER", sAssemblyPath, RegistryValueKind.String);
  regAppAddInKey.SetValue("MANAGED", 1, RegistryValueKind.DWord);



   Interface Design

   Now I know how to creat commands, how to load, how to load automatically, and finally I intend to design an interface
   But the only way I know is to create . cuix file by Customize User Interface Editor ,add toolbar, buttons, icons, and macros as shown below

Customize User Interface Editor.PNG


   I recall myToolbar, then click the only button with mouse, the program is executed HW command as follows



   but there is a problem, the interface file. cuix and functional document .dll are two files, the user needs to load separately, do not feel good




  I'm wondering how I deal with the above problems
   I think there should be a conventional method, possibly, using C # code to achieve the interface and achieve the functional at the same time, and finally compiled into olny one .dll file
   If, as I suspect, and I hope I can find some C # code
   Sincerely thanks

Re: Create Toolbar with C#

01-01-2014 07:43 AM in reply to: HelloWorlddd

   Function create by C #, and then compiled into dll files, functions automatically loaded by RegisterMyApp() , it’s referenced from AutoCAD. NET Developer's Guide,then the command will auto load very time.


   User interface design by Customize User Interface Editor, and then save as .cuix file, load the user interface using the following code, in fact, equivalent to input CUILOAD in command prompt, but this CUILOAD need only be entered once, it does not need to load very time


   Here is the way I take, they can be set simultaneously, only one time, perhaps there is a better way, but now I only know this way





 the following code is copy form http://forums.autodesk.com/t5/NET/Accessing-toolbars-and-buttons-programatically/m-p/3182594/highlig...

string flName = csGavin.CUIFileBaseName;
Application.DocumentManager.MdiActiveDocument.SendStringToExecute("_cuiunload " + flName + " ",false,false,false);
Application.DocumentManager.MdiActiveDocument.SendStringToExecute("_cuiload " + flName + " filedia 1 ",false,false,false);
