AttachExternalReference problem

[Anonymous]

I want use objectDBX to AttachExternalReference ,but always encount fator error,could someone tell me how to solve it?

string[] fileNames = new string[] { "Ref_S_Plan", "Ref_S_Beam", "Ref_S_Foot" };

AxDbDocumentClass axdoc = new AxDbDocumentClass();
string newName;
newName = subFolder + "\\" + fileNames[0] + ".dwg";
axdoc.SaveAs(newName, null);

AxDbDocumentClass axdoc1 = new AxDbDocumentClass();
newName = subFolder + "\\" + fileNames[1] + ".dwg";
axdoc1.SaveAs(newName, null);

AxDbDocumentClass axdoc2 = new AxDbDocumentClass();
newName = subFolder + "\\" + fileNames[2] + ".dwg";
axdoc2.SaveAs(newName, null);

double[] insertPnt = new double[] { 0, 0, 0 };
double scale = 1;
double rotation = 0;
bool bOverlay = false;
try
{
System.Runtime.InteropServices.Marshal.ReleaseComObject(axdoc);
}
catch { }

string refFileNameNoext;
refFileNameNoext = fileNames[0];
axdoc1.ModelSpace.AttachExternalReference(subFolder, refFileNameNoext, insertPnt,
scale, scale, scale, rotation, bOverlay, null);

refFileNameNoext = fileNames[0];
axdoc2.ModelSpace.AttachExternalReference(subFolder, refFileNameNoext, insertPnt,
scale, scale, scale, rotation, bOverlay, null);

try
{
System.Runtime.InteropServices.Marshal.ReleaseComObject(axdoc1);
System.Runtime.InteropServices.Marshal.ReleaseComObject(axdoc2);
}
catch { }

What is the error that you are encountering? On what line?

There are too many variables here to actually reproduce the error. What is
the error that you are getting? Does AutoCAD simply vaporizes or does it
display some error?

I have found the problem.I misunderstanding the first parameter, but a new problem appear, the ExternalReference doesn't attached to axdoc1 and axdoc2,but attached to the current drawing in autocad.

[Anonymous]

the following is my current code,the problem is line is added to axdoc1 and axdoc2, but External Reference isn't attached to axdoc1 and axdoc2,but attached to current drawing in autocad, it's so strange.
private static void CreateRefDrawing(String subFolder)
{
string[] fileNames = new string[] { "Ref_S_Plan", "Ref_S_Beam", "Ref_S_Foot" };

AxDbDocumentClass axdoc = new AxDbDocumentClass();
string newName = subFolder + "\\" + fileNames[0] + ".dwg";
axdoc.SaveAs(newName, null);
System.Runtime.InteropServices.Marshal.ReleaseComObject(axdoc);


AxDbDocumentClass axdoc1 = new AxDbDocumentClass();
string newName1 = subFolder + "\\" + fileNames[1] + ".dwg";
//axdoc1.SaveAs(newName1, null);

AxDbDocumentClass axdoc2 = new AxDbDocumentClass();
string newName2 = subFolder + "\\" + fileNames[2] + ".dwg";
////axdoc2.SaveAs(newName2, null);

double[] insertPnt = new double[] { 0, 0, 0 };
double scale = 1;
double rotation = 0;
bool bOverlay = false;

axdoc1.ModelSpace.AddLine(new double[] { 0, 0, 0 }, new double[] { 1000, 1000, 0 });
axdoc1.ModelSpace.AttachExternalReference(newName, fileNames[0], insertPnt, scale, scale, scale, rotation, bOverlay, null);

axdoc2.SaveAs(newName2, null);
System.Runtime.InteropServices.Marshal.ReleaseComObject(axdoc2);

Can say if this will work, but it may be
worth a try:

1. Get the managed Database from the AcadDatabase, using
Database.FromAcadDatabase(AxDbDocument.Database)

2. Save the value of HostApplicationServices.WorkingDatabase

3. Set HostApplicationServices.WorkingDatabase to the
Database obtained from the AcadDatabase.

4. Attach the xref

5. Set the value of HostApplicationServices.WorkingDatabase
back to the original value saved previously.

thanks tony,I do as you suggested,but it still doesn't work for me , a fatal error will appeare when attacth external reference.

double[] insertPnt = new double[] { 0, 0, 0 };
double scale = 1;
double rotation = 0;
bool bOverlay = false;

Database curdb = HostApplicationServices.WorkingDatabase;

Database db = Database.FromAcadDatabase(axdoc1.Database);
HostApplicationServices.WorkingDatabase = db;

// the following line will cause a fatal error,
axdoc1.ModelSpace.AttachExternalReference(newName, fileNames[0], insertPnt, scale, scale, scale, rotation, bOverlay, null);

System.Runtime.InteropServices.Marshal.ReleaseComObject(axdoc1);

HostApplicationServices.WorkingDatabase = curdb;

I don't know if this is your problem but in your code,
you do this:

Database curdb = HostApplicationServices.WorkingDatabase;

Database db = Database.FromAcadDatabase(axdoc1.Database);
HostApplicationServices.WorkingDatabase = db;

//...

axdoc1.ModelSpace.AttachExternalReference(newName,
fileNames[0], insertPnt, scale, scale, scale, rotation, bOverlay, null);

axdoc1.SaveAs(newName1, null);

System.Runtime.InteropServices.Marshal.ReleaseComObject(axdoc1);

When you call ReleaseComObject(axdoc1), the Database that it
wraps is destroyed while it is the current 'WorkingDatabase',
which is almost certainly going to blow up.

Try restoring the WorkingDatabase back to curdb before
you let go of axdoc1.

I tried another mothod ,and it work fine,so I think it's a bug in objectdbx.
by the way ,could someone know how to attach external reference with arx, and how to close a docment with arx.

the following is my modified codes ,it works fine.


private static void CreateRefDrawing(string subFolder)
{
string[] fileNames = new string[] { "Ref_S_Plan", "Ref_S_Beam", "Ref_S_Foot" };

AxDbDocumentClass axdoc = new AxDbDocumentClass();
string newName = subFolder + "\\" + fileNames[0] + ".dwg";
axdoc.SaveAs(newName, null);
System.Runtime.InteropServices.Marshal.ReleaseComObject(axdoc);

AxDbDocumentClass axdoc1 = new AxDbDocumentClass();
string newName1 = subFolder + "\\" + fileNames[1] + ".dwg";
axdoc1.SaveAs(newName1, null);
//System.Runtime.InteropServices.Marshal.ReleaseComObject(axdoc);

AxDbDocumentClass axdoc2 = new AxDbDocumentClass();
string newName2 = subFolder + "\\" + fileNames[2] + ".dwg";
axdoc2.SaveAs(newName2, null);


double[] insertPnt = new double[] { 0, 0, 0 };
double scale = 1;
double rotation = 0;
bool bOverlay = false;

try
{
//// the following comment line will cause a fatal error

//Database curdb = HostApplicationServices.WorkingDatabase;
//Database db = Database.FromAcadDatabase(axdoc1.Database);
//HostApplicationServices.WorkingDatabase = db;
//axdoc1.ModelSpace.AttachExternalReference(newName, fileNames[0], insertPnt, scale, scale, scale, rotation, bOverlay, null);
//axdoc1.SaveAs(newName1, null);
//HostApplicationServices.WorkingDatabase = curdb;

string refName = ".\\" + fileNames[0] + ".dwg";
AcadDocument doc1 = ActiveX.AcadApp.Documents.Open(newName1, false, null);
doc1.ModelSpace.AttachExternalReference(refName, fileNames[0], insertPnt, scale, scale, scale, rotation, bOverlay, null);
doc1.Close(true, newName1);

AcadDocument doc2 = ActiveX.AcadApp.Documents.Open(newName2, false, null);
doc2.ModelSpace.AttachExternalReference(refName, fileNames[0], insertPnt, scale, scale, scale, rotation, bOverlay, null);
doc2.Close(true, newName2);

Is my judgement correct? has External reference a bug in objectdbx?

[Anonymous]

This was logged in our bug tracking database. Nobody looked into it yet so I
can't confirm or deny. It looks suspeciously like a bug.
