Use of Window.Focus in AutoCAD 2014                                                        By Balaji Ramamoorthy
The new API in AutoCAD 2014 includes the Window.Focus method. This method is very useful if you were using palette to call a command that requires AutoCAD to prompt for user input. In earlier versions of AutoCAD, the AutoCAD editor did not receive focus until the editor was clicked. This was a bit troublesome as it required an additional mouse click. The way to overcome it was to either call the "SetFocus" Win32 API through a dllimport or to use an internal undocumented method : "Internal.Utils.SetFocusToDwgView".
With AutoCAD 2014, the "Window.Focus" method can be used instead. As an example, if you had a button in the palette to insert a block named "Autodesk", then you can use the Window.Focus method from the button click callback method as :

1. using Autodesk.AutoCAD.ApplicationServices;
   
2. using AAA = Autodesk.AutoCAD.ApplicationServices;
   
3. private void InsertBlockBtn_Click(object sender, EventArgs e)
   
4. {
   
5.     AAA.Document activeDoc
   
6.             = AAA.Application.DocumentManager.MdiActiveDocument;
   
7.     dynamic acadDocObj = activeDoc.GetAcadDocument();
   
8.     activeDoc.Window.Focus();
   
9.     acadDocObj.SendCommand(String.Format("-Insert\nAutodesk\n"));
   
10. 
    
11.     //            or
    
12. 
    
13.     //object acadDocObj = activeDoc.GetAcadDocument();
    
14.     //activeDoc.Window.Focus();
    
15.     //object[] OnedataArry = new object[1];
    
16.     //OnedataArry[0] = String.Format("-Insert\nAutodesk\n");
    
17.     //acadDocObj.GetType().InvokeMember(
    
18.     //  "SendCommand",
    
19.     //  System.Reflection.BindingFlags.InvokeMethod,
    
20.     //  null, acadDocObj, OnedataArry
    
21.     //);
    
22. 
    
23. }
    

using Autodesk.AutoCAD.ApplicationServices;<br /> using AAA = Autodesk.AutoCAD.ApplicationServices;<br /> private void InsertBlockBtn_Click(object sender, EventArgs e)<br /> {<br />     AAA.Document activeDoc<br />             = AAA.Application.DocumentManager.MdiActiveDocument;<br />     dynamic acadDocObj = activeDoc.GetAcadDocument();<br />     activeDoc.Window.Focus();<br />     acadDocObj.SendCommand(String.Format("-Insert\nAutodesk\n")); <br /> <br />     //            or <br /> <br />     //object acadDocObj = activeDoc.GetAcadDocument();<br />     //activeDoc.Window.Focus();<br />     //object[] OnedataArry = new object[1];<br />     //OnedataArry[0] = String.Format("-Insert\nAutodesk\n");<br />     //acadDocObj.GetType().InvokeMember(<br />     //  "SendCommand",<br />     //  System.Reflection.BindingFlags.InvokeMethod,<br />     //  null, acadDocObj, OnedataArry<br />     //);<br /> <br /> }<br />
