Assembly reference

Hi friends, in this post, what assembly reference do I need to get rid of the missing assembly reference issue. I am getting red squiggly lines for Properties and BitmapImage. I tried all the assemblies I could think of, including System.Drawing and System.Windows. Thanks in advance for your help. Following is an image of the issue.

Did you copy-pasted the code from outside of the project? it looks like you are doing ribbon stuff, which required references to WPF related system assemblies:

PresentationFramework

PresentationCore

System.Xaml

WindowsBase

Of course you also need

acWindows.dll

adWindows.dll

Once you have these referenced, simply right click the squiggly "BitmapImage" Visual Stuido should suggests adding

"using System.Windows.Media.Imageing;" namespace.

As for "Properties.Resources...", it would only be available if you created Resources in your project: go to "Project->Properties->Resources tab" and create needed image resources, in your case, they are a bunch of image files to be read into the resources.

Thanks @norman.yuan, this did the trick. I was able to load the ribbon. A new problem arises. The ribbon keeps loading a new instance every time I call simplebutton. Based on the post that is not the behavior I expected. Following is my code which is exactly from the previously posted link. Can you please check if it does the same for you.

using System; using System.Collections; using System.Collections.Generic; using System.Text; using System.Linq; using System.Xml; using System.Reflection; using System.ComponentModel; using System.Windows; using System.Media; using System.Windows.Forms; using System.Windows.Media.Imaging; using System.Windows.Media; using System.Drawing; using System.IO; using System.Threading.Tasks; using System.Diagnostics; using Autodesk.AutoCAD.ApplicationServices; using Autodesk.AutoCAD.DatabaseServices; using Autodesk.AutoCAD.EditorInput; using Autodesk.AutoCAD.Geometry; using Autodesk.AutoCAD.Runtime; using Autodesk.Windows; using AcAp = Autodesk.AutoCAD.ApplicationServices.Application; [assembly: ExtensionApplication(typeof(ManagedApplication.Initialization))] [assembly: CommandClass(typeof(ManagedApplication.Commands))] namespace ManagedApplication { public class Initialization : Autodesk.AutoCAD.Runtime.IExtensionApplication { public void Initialize() { Active.Ed.WriteMessage("Initializing - do something useful."); } public void Terminate() { Debug.WriteLine("Cleaning up..."); } } public class Commands { [CommandMethod("SimpleButton")] public void SimpleButton() { Autodesk.AutoCAD.ApplicationServices.Application.SystemVariableChanged += new Autodesk.AutoCAD.ApplicationServices.SystemVariableChangedEventHandler(Application_SystemVariableChanged); Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument.CommandEnded += new CommandEventHandler(MdiActiveDocument_CommandEnded); CreateSimpleButton(); } void MdiActiveDocument_CommandEnded(object sender, CommandEventArgs e) { if (e.GlobalCommandName == "QUICKCUI" || e.GlobalCommandName == "CUI") Autodesk.AutoCAD.ApplicationServices.Application.Idle += new EventHandler(Application_Idle); } void Application_Idle(object sender, EventArgs e) { if (Autodesk.Windows.ComponentManager.Ribbon != null) { Autodesk.AutoCAD.ApplicationServices.Application.Idle -= new EventHandler(Application_Idle); CreateSimpleButton(); } } void Application_SystemVariableChanged(object sender, Autodesk.AutoCAD.ApplicationServices.SystemVariableChangedEventArgs e) { if (e.Name == "WSCURRENT") { string cmdNames = (string)Autodesk.AutoCAD.ApplicationServices.Application.GetSystemVariable("CMDNAMES"); if (cmdNames.ToUpper().IndexOf("QUICKCUI") >= 0 || cmdNames.ToUpper().IndexOf("CUI") >= 0) return; CreateSimpleButton(); } } public void CreateSimpleButton() { Autodesk.Windows.RibbonControl ribbonControl = Autodesk.Windows.ComponentManager.Ribbon; RibbonTab Tab = new RibbonTab(); Tab.Title = "Test Ribbon"; Tab.Id = "TESTRIBBON_TAB_ID"; ribbonControl.Tabs.Add(Tab); Autodesk.Windows.RibbonPanelSource srcPanel = new RibbonPanelSource(); srcPanel.Title = "Panel1"; RibbonPanel Panel = new RibbonPanel(); Panel.Source = srcPanel; Tab.Panels.Add(Panel); Autodesk.Windows.RibbonButton button1 = new RibbonButton(); button1.Text = "Button"; button1.Size = RibbonItemSize.Large; button1.Image = getBitmap(EnsureRibbon.Properties.Resources.Apps, 32, 32); button1.LargeImage = getBitmap(EnsureRibbon.Properties.Resources.Apps, 32, 32); button1.ShowText = true; button1.CommandParameter = "._LINE "; button1.CommandHandler = new SimpleButtonCmdHandler(); srcPanel.Items.Add(button1); Tab.IsActive = true; } BitmapImage getBitmap(Bitmap bitmap, int height, int width) { MemoryStream stream = new MemoryStream(); bitmap.Save(stream, System.Drawing.Imaging.ImageFormat.Png); BitmapImage bmp = new BitmapImage(); bmp.BeginInit(); bmp.StreamSource = new MemoryStream(stream.ToArray()); bmp.DecodePixelHeight = height; bmp.DecodePixelWidth = width; bmp.EndInit(); return bmp; } public class SimpleButtonCmdHandler : System.Windows.Input.ICommand { public bool CanExecute(object parameter) { return true; } public event EventHandler CanExecuteChanged; public void Execute(object parameter) { if (parameter is RibbonButton) { string esc = ""; string cmds = (string)Autodesk.AutoCAD.ApplicationServices.Application.GetSystemVariable("CMDNAMES"); if (cmds.Length > 0) { int cmdNum = cmds.Split(new char[] { '\'' }).Length; for (int i = 0; i < cmdNum; i++) esc += '\x03'; } RibbonButton button = parameter as RibbonButton; Document doc = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument; doc.SendStringToExecute(esc + button.CommandParameter,true, false, false); } } } } }

I can probably move the code to a startup reactor or something and eliminate the multiple command issue. But I am not sure why calling cui loads a new ribbon each time. I will be grateful for any insight. The following screencast shows the issue.

When your ribbon tab building code CreateSimpleButton() method starts run, it should first check if there is a ribbon tab with the same Title and/or Id exist. If yes, the code either no need to go further, or remove it and rebuild a new one. Although each tab in ribbon has a property "Id", but there is no measure in AutoCAD to prevent tabs have duplicated Id. So, your code would look like this:

public void CreateSimpleButton()

{

var ribbonControl = Autodesk.AutoCAD.Componentanager.Ribbon;

// loop through all tabs to compare its name, if found, stop ribbon tab building

If (FindExistingTab(ribbonControl, "Test Ribbon") return;

// start building new tab here

var tab= new RibbonTab();

... ...

}

private bool FindExistingTab(RibbonControl control, string tabName)

{

... ....

}

Thanks! I will give that a shot.
