I think you can use SendCommand,

Dear Mr. Hallex,

Thanks for your quick response,

In my coding,

<quote>

conststring progID = "AutoCAD.Application.18";

AcadApplication acApp = null;

try

{

acApp = (AcadApplication)Marshal.GetActiveObject(progID);

}

catch

{

try

{

Type acType = Type.GetTypeFromProgID(progID);

acApp = (AcadApplication)Activator.CreateInstance(acType,true);

}

catch

{

MessageBox.Show("Cannot create object of type \"" + progID + "\"");

}

if (acApp != null)

{

acApp.Visible =true;

acApp.ZoomExtents();

acApp.ActiveDocument.SendCommand("oleopen\r");

}

the error which i am getting is

<quote>

Command: oleopen

Unable to find OLE object. Object must be selected before entering the
OLESCALE command.

I have tried with the reference link sent by you,

Similarly I have tried to select the Ole Object and then to SendCommand "Oleopen", But I am getting some errors.

<quote>

using (Transaction t = db.TransactionManager.StartTransaction()) {
BlockTableRecord bt = t.GetObject(db.CurrentSpaceId, OpenMode.ForRead) as BlockTableRecord;
foreach (ObjectId id in bt) {
if (id.ObjectClass.Name != "AcDbOle2Frame")
continue;
Ole2Frame oleFrame = t.GetObject(id, OpenMode.ForRead) as Ole2Frame;
IntPtr ptrClientItem = AcDbOle2Frame_getOleClientItem(oleFrame.UnmanagedObject);
COleClientItem_CopyToClipboard(ptrClientItem, 0);
}
t.Commit();

Could you please help me?

regards,

Micky.

If this ole object was inserted to model spce

try this code, tested on my A2010

Don't forget to release AcadApplication at the end of code

      public void TestFindOle()
       {
       const string progID = "AutoCAD.Application.18";

           

AcadApplication acApp = null;

           

try

            {

acApp = (AcadApplication)Marshal.GetActiveObject(progID);

            }

           

catch

            {

               

try

                {

                   

Type acType = Type.GetTypeFromProgID(progID);

                    acApp = (AcadApplication)Activator.CreateInstance(acType,true);

                }

               

catch

                {

                   

MessageBox.Show("Cannot create object of type \"" + progID + "\"");

                }

            }

           

if (acApp != null)

            {

                acApp.Visible =true;

                
    AcadDocument AcadDoc = acApp.ActiveDocument;
    
    acApp.Documents.Open(@"C:\Test\mtext.dwg", Type.Missing, Type.Missing);
        AcadModelSpace AcSpace = AcadDoc.ModelSpace;
        acApp.ZoomExtents();
        AcadOle AcOle = null;
            //loop through the model space to fill the list of block references
            foreach (AcadEntity AcEnt in AcSpace)
            {
                if (AcEnt is AcadOle)
                {
             
                    AcOle  = AcEnt as AcadOle;
                  if (AcOle != null)
                  {
                      string hand = AcOle.Handle;
                      acApp.ActiveDocument.SendCommand("select " + "(handent " + "\"" + hand + "\"" + ")  ");
                     
                      acApp.ActiveDocument.SendCommand(string.Format("_oleopen  \"{0}\" \r","L"));
                  }
                    
                }
            }


            }

       }

Dear Sir,

Thanks very much for your support,

Since my OLE object is in Paper space,

I just modified your coding to paper space only,

everything working well but ole open command is not working,

please see the below coding,

<quote>

(acApp != null)

{

acApp.Visible =

true;

AcadDocument doc1 = acApp.ActiveDocument;

acApp.Documents.Open(

"D:/test.dwg");

acApp.Application.Visible =

true;

acApp.Application.WindowState = Autodesk.AutoCAD.Interop.Common.

AcWindowState.acMax;

acApp.WindowState = Autodesk.AutoCAD.Interop.Common.

AcWindowState.acMax;

acApp.ActiveDocument.Application.ZoomExtents();

Autodesk.AutoCAD.Interop.Common.

AcadPaperSpace AcSpace = doc1.PaperSpace;

Autodesk.AutoCAD.Interop.Common.

AcadOle AcOle = null;

//loop through the model space to fill the list of block references

foreach (Autodesk.AutoCAD.Interop.Common.AcadEntity AcEnt in AcSpace)

{

if (AcEnt is Autodesk.AutoCAD.Interop.Common.AcadOle)

{

AcOle = AcEnt

as Autodesk.AutoCAD.Interop.Common.AcadOle;

if (AcOle != null)

{

string hand = AcOle.Handle;

acApp.ActiveDocument.SendCommand(

"select " + "(handent " + "\"" + hand + "\"" + ") ");

acApp.ActiveDocument.SendCommand(

string.Format("_oleopen \"{0}\" \r", "L"));

}

MessageBox.Show("tested OK");

best regards,

Micky.

What is the ole object you've inserted in your drawing?

I'm using Excel for my test

Dear Sir,

Season Greetings,

Sorry to bother you.

since the drawing file size is around 2 MB, there is a error while uploading.

Could you please send me your Email Id to send the drawing file?

I think the problem is in selecting the OLE object,

the program was ignoring the selection,

<quote>

Autodesk.AutoCAD.Interop.Common.AcadPaperSpace AcSpace = doc1.PaperSpace;

Autodesk.AutoCAD.Interop.Common.AcadOle AcOle = null;

//loop through the model space to fill the list of block references foreach (Autodesk.AutoCAD.Interop.Common.AcadEntity AcEnt in AcSpace) { MessageBox.Show("Foreach OK");

if (AcEnt is Autodesk.AutoCAD.Interop.Common.AcadOle) { AcOle = AcEnt as Autodesk.AutoCAD.Interop.Common.AcadOle; if (AcOle != null) { string hand = AcOle.Handle; acApp.ActiveDocument.SendCommand("select " + "(handent " + "\"" + hand + "\"" + ") ");

MessageBox.Show("OLE selected..");

acApp.ActiveDocument.SendCommand(string.Format("_oleopen \"{0}\" \r", "L")); } } }

best regards,

Micky.
