Revit 2010 API "Add Hello World Ribbon Panel"

[jlucero]

Has anyone had trouble with the "2.3 Walkthrough: Add Hello World Ribbon Panel" working? I am trying to do it with MS Visual C# Express Edition. I had no trouble with the Hello World program. The errors I am getting with this one are:

Error 1 Cannot implicitly convert type 'Autodesk.Revit.PushButton' to 'Autodesk.Revit.PulldownButton' CsAddPanel.cs 17 41 AddPanel

Error 2 The type or namespace name 'BitmapImage' could not be found (are you missing a using directive or an assembly reference?) CsAddPanel.cs 22 13 AddPanel

Error 3 The type or namespace name 'BitmapImage' could not be found (are you missing a using directive or an assembly reference?) CsAddPanel.cs 22 42 AddPanel


In the walkthrough sample within the PDF, it shows "BitmapImage" as being recognized by the compiler. It's not in the Express Edition. My guess is I am missing a reference?

I have as references RevitAPI, PresentationCore, System.Windows.Forms and WindowsBase. What am I missing here?

For Error 1 Cannot implicitly convert .....
Please check your line that says
PushButton pushButton = ribbonPanel.{color:#0000ff}AddPushButton{color}("HelloWorld",.....); //Line 17 in csAddPanel.cs
Make sure that the words in Blue are AddPushButton in your file and {color:#ff0000}NOT AddPullDownButton{color}("....... "); //This can happen occassionally.

For Error 2 and 3 ... You are right ! You are missing a reference.
Add a reference to "System.Drawing" and you should be ok.

Hope that helps !

Thanks ppathak!
I was able to find out the missing references. I opened one of the samples that uses the "BitmapImage" and used the same one the sample uses. That worked.

As far as the:

Error 1 Cannot implicitly convert type 'Autodesk.Revit.PushButton' to 'Autodesk.Revit.PulldownButton' CsAddPanel.cs 24 41 AddPanel

I still need to figure it out. I'll look into what you wrote in your reply and double check my code.

Thanks again.

You were right ppathak.

I had:

PullDownButton pushButton = ribbonPanel.AddPushButton

instead of

PushButton pushButton = ribbonPanel.AddPushButton

Thanks!
