Assembly reference

[karl.sch1983]

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.

                    string cmds = (string)Autodesk.AutoCAD.ApplicationServices.Application.GetSystemVariable("CMDNAMES");

                    if (cmds.Length > 0)

                        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.
