HowTo Suppress a Save Dialog Box.

[rberghLJ4SA]

Hi

We running an AutoCAD Extension. We aslo set the system variable SDI to 1 (Single Document Interface).

When I use 

Application.DocumentManager.Open

 A save dialog pops up, I need to suppress this dialog. I've tried CloseAndSave but because we're running SDI a document must be open. So basically when I open a doc the active doc will be closed I just don't want the active doc saved.

Did you tried this, 

   For intI = 0 To Acadapp.Documents.Count - 1 
       Acadapp.Documents.Item(intI).Close(SaveChanges:=False)
       Next

Doesn't work we're in Single Document Interface Mode ... Cannot close the document.

Did you try Cmddia variable to 0.

Thanks for your suggestion, unfortunately that did not work.

if it is ok and you do not feel irritated, can you send a video, so that i can understand the sequence

I would suggest that you try doing a SaveAs to a file in the temp folder and always overwrite any existing file so that the drawing is not in an unsaved state and the save dialog won't appear. I honestly don't think that there's any other way around that problem.

Sorry if I can across as irretated, I wasn't. I happy to try anything at this point

I am going try that now.

object obj = Autodesk.AutoCAD.ApplicationServices.Application.GetSystemVariable("DWGTITLED");

        // Check to see if the drawing has been named
        if (System.Convert.ToInt16(obj) == 0)
        {
            if (File.Exists(Path.Combine(FileHandler.AppDataInstancePath(), "WorkingDoc.dwg")))
            {
                Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument.Database.SaveAs(Path.Combine(Environment.ExpandEnvironmentVariables("%temp%"),"temp.dwg"),true,DwgVersion.Current,null);
                //Still showing save dialog on Open...
                Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.Open(Path.Combine(FileHandler.AppDataInstancePath(), "WorkingDoc.dwg"));
            }

            Document acDoc = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument;
            string strDWGName = acDoc.Name;
            acDoc.Database.SaveAs(Path.Combine(FileHandler.AppDataInstancePath(), "WorkingDoc.dwg"), true, DwgVersion.Current, null);

        }

This is what I've tried, I still get a Save dialog on opening of the WorkingDoc.dwg. Even after saving the default drawing to a temp folder.

Btw this is running in Application context during initialization of AutoCAD.

Can you try this sequence and tell.

  'EndAcadTasks()
  Acadapp = CreateObject("AutoCAD.Application")
  Acadapp.Visible = True
  Acadapp.WindowState = AcWindowState.acMax
  Acaddoc = Acadapp.ActiveDocument
  Acaddoc.SetVariable("SDI", 1)
  Acadapp.Documents.Open("e:\testcad.dwg")

'''' code for endAcadTasks if required 
Public Sub EndAcadTasks()
     Try
         Dim processes As Process() = Process.GetProcessesByName("acad")
         For Each proc As Process In processes
             proc.Kill()
         Next
     Catch ex As Exception
         MsgBox("Error ending acad.exe tasks: " & ex.Message)
     End Try
 End Sub

I would try using the COM AcadDocument.SaveAs() method.
