AutoCAD .NET :: Error When Submitting Result Buffer To Xdata
Feb 21, 2013
I'm taking over some code from a developer that is no longer here. Right now when the code saved a resultbuffer object to xdata, I get an eregappidnotfound. Due to various forums, I believe this is because the ID is not being registered with the database before it's being inserted.
The error is thrown on this line: XData.ToXData(partCollection);
using (Autodesk.AutoCAD.DatabaseServices.DBObject dbObj = t.GetObject(objId, Autodesk.AutoCAD.DatabaseServices.OpenMode.ForWrite)){ DeviceName.SetDeviceName((Autodesk.AutoCAD.DatabaseServices.BlockReference)dbObj, txtDeviceName.Text);
dbObj.XData = XData.ToXData(partCollection); t.Commit();}
The code for the ToXData function is here:
public static ResultBuffer ToXData(PartCollection Parts) { //Write out some header information ResultBuffer rb = new ResultBuffer(new TypedValue(System.Convert.ToInt32(DxfCode.ExtendedDataRegAppName), XDATA_APP_NAME), new TypedValue(System.Convert.ToInt32(DxfCode.ExtendedDataInteger16), XDATA_TYPE), new [code].......

I would like AMAP to perform a BUFFER operation on a certain SHP, so the resulting buffer polygons would get the table attributes from that original shape, and also be exported as a SHP.
It is mandatory that a buffer polygon will have the same attributes from the original SHP line, including its FeatID.
Is it possible?

I have several SHP Connections that I am using as background. I can use the Style Editor to get the individual SHP Lines/Polygons/blocks to be the appropriate colors for the information that they include (Property Lines, Buildings, Utilities, etc)
The problem is in plotting this information. The settings in my tried and true .ctb file don't seem to apply to the SHP data. Everything else that actually exists in the drawing behaves correctly, but the SHP data plots as it appears on the screen.

When I send a job to net render with BB I'm getting a lockup
I send the job, connect then hit Submit and then get the lockup
The job still submits after some time but I always have to force the program to respond. Sometimes the program will respond with 'not connected' other times I'm forced to quit
The job still renders fine - Update installed a few days ago.

I am familiar with GIS but I am new to AutoCAD Map 2012.
I have 140,000 lines and 20,000 points.
I would like to have all points closer than 1 meter to a line.
This is what I tried to do:
buffer the lines (_mapfdobuffercreate)overlay points and buffer (_MapGisOverLay) to get all points in the buffer area
This works well with a small amount of data.But in step 1 I have to select all lines (140,000) with the mouse. When I try to select all lines with the mouse AutoCAD Map freezes after some minutes. Is there a way with AutoCAD to work on a “layer basis” and not on a “selection set basis”. Other GIS (ESRI, Quantum, …) work with a complete layer.
In this analysis I work with FDO Data (shp,sqlite,sdf). I have geometries, but no attribute data.

I am trying to create a 150m buffer around points from a map features that I have attached from an SDF.
If I select any amount of points to buffer I get the following error:Unable to complete buffer operation
Using Civil 3D 2011 (come with Map 3D of course) 64 bit on a window 64 bit machine. Tried attaching sqlite db with no luck, then exported to SDF attached to dwg as datasource, themed, etc... tried feature buffer analysis again... same error.

Why this code doesn't modify the xdata. I copied and modified another post.
it doesn't throw any errors. and objNewResBuf seems to have the right data.

I`m not sure if this is possible or not.
Is there any way to write a script which copy`s a variable to the buffer? Similar to CTRL-C?

I am trying to store some data to polyline entities. and I'm planning to use xdata. Is it possible to store some string and integer values? Also each of them should have a tag name like block attiribute names.
For example:
Type= "XLPE"
Capacity= "Medium"
LengthMultiplier= 3
thickness=5
etc.
I searched internet for utilizing xdata, and it seems that Xdata is only for predefined types such as: datalayername, dataycoordinate, datazcoordinate,datascale etc. And it seems it is not possible to store more than one string with tag name.

When capturing the Object Appended event of a block containing a "Drawing_No" attribute tag, then trying to add xdata to the object, I get a "Object reference not set to an instance of an object" error. I've tried writing the XData after committing the transaction but it didn't work.
If TypeOf e.DBObject Is BlockReference Then Dim bref As BlockReference = DirectCast(e.DBObject, BlockReference) If bref.AttributeCollection.Count <> 0 Then For Each attId As ObjectId In bref.AttributeCollection Dim attRef As AttributeReference = trans.GetObject(attId, OpenMode.ForRead) Select Case attRef.Tag Case "DRAWING_NO" WriteTitleBlock(e.DBObject.ObjectId) '<<Subroutine used to add XData Exit For End Select Next End If End If

I have a lot of lines that I need a length, like in attached file. At this moment I do it with a vba that put fields in all lines.
The problems:
1) fields makes drawing slow to regen or after I modify line.
2) fields not follow lines slopes and position, if I stretch or move one end point of line. Text must be in middle of line.
So I thinking use reactors .
I tried reactor but I don't have much experience in lisp and I am having problems with persistent reactors, after I close file and open again, load lisp. Reactor not continue persistent.
This is a test that I tried. Works only for one line.
(defun print-align-text ( owner reactor lst / sp ep a d )
(setq sp (vlax-curve-getstartpoint line1))
(setq ep (vlax-curve-getendpoint line1))
[Code].....
I have read that is better store data using XData. In VBA I tried construct class module with events, without any success.

I'm trying to use a Selection Filter on Block Reference XData value. But I get no hits, it works fine with Lines and Polylines that has the same kind of XData.
Is it a bug or do I have to define my Selection Filter differently when working with Block Reference?
Here is a part of the code :
TypedValue[] flt = new TypedValue[]
{
new TypedValue(-4, " new TypedValue(-4, " new TypedValue(8, "POLYLINE_LAYER"),
new TypedValue(1001, "Object_Id"),
new TypedValue(1000, "166448"),
new TypedValue(-4, "AND>"),

My code add xdata to any object properly except for a dynamic block with attribute. After code excutes it disappears from screen . Even undo make strange thing. I guess I screw the database somehow. But even audit doesn't show any fix applied.
Attach is a sample drawing. And below is my code.
<CommandMethod("pppp")> _ Shared Sub test1()
Dim Mydwg As Document = Application.DocumentManager.MdiActiveDocument
Dim Mydb As Database = Mydwg.Database Dim Myed As Editor = Mydwg.Editor
Dim MyRegisterApplication As String = "My_R_Cad"

with a function like this I added some xdata, some MULTILEADER
(defun c:add_xdata () (princ "Select: ") (setq ogg (car (entsel))) (addXdata ogg "TEST" "CODICE" "1256") (addXdata ogg "TEST" "MATERIALE" "LEGNO") (addXdata ogg "TEST" "TIPO" "A"))
Now with the following function can only select leaders who have linked the xdata application TEST
(setq selez_all (ssget "X" '((0 . "MULTILEADER")(-3 ("TEST")))))
I can not, however, find a way to select all MULTILEADER who have a particular value of XData.
For example I would select all MULTILEADER with MATERIALE = "LEGNO" and TIPO = "A".

I have LT 2012. I use Excel 2010 into my drawings to set up tables. When I opened the drawing I've been working on, I had lost all of yesterday's data. Command History shows dozens of these notations, "AcDbLine(41859) XData Handle Unknown, Null" In Help it says you can no longer turn handles off, so it should be ON. How can I point the drawing to my Excel data?

I've burned like 9 DVDs without issue using ulead. I'm now burning another, but have wasted 4 DVDs since I am getting a dialog, right near the end of the actual burn for:
"Data buffer underrun. The computer may be too busy with other tasks or may not have enough power to keep the specified burning speed. [534:-2147216284:0]"
All movies are about the same length (120m) and all settings are the same. My computer is a 4.6Ghz dual core AMD with 2G RAM. I'm writing to a HD with 200G free; local disk has 120G free. No other apps open.
This is the first time I've received this error; I've totally recreated a vsp project and everything, but I still get this error. I've modified so that the burn is only at 4x, which is shows is the minimum? The option to enable buffer underrun is disabled and I can't select it. I'm doing a two-pass conversion just like all my other successful burns.

"An internal error occurred when overlapped buffer is full."
That is the message I am receiving when I try to make my project into a video or audio file.
I have two audio tracks which have only two effects added to them.

Is there a way to prevent the render window from clearing to black before rendering a new frame when using the scanline renderer? Several versions ago Max used to leave the old image up while updating and its easier for me in some cases to see changes when the previous frame is still there and updates as the scanline renders down the frame.

I need a Reactor to Modify Xdata - Length - contained in Line Object if this Line is modified (stretched, breaked, trimmed, etc).The routine need to verify if Line contain Xdata and modify it (and works with multiple selection).
I tried for long hours, but without success. I tried to create a list of entities while the reactor is applied, but doing so need another reactor to change these entities after the first Reactor works.The codes I used are below:
{code}
;If it just 1 string only you want to add
(defun add_xdata_str (e a v);;;EName APPID String_value
(and (not (tblsearch "APPID" a))
(regapp a))

I am trying to create a custom art brush, but its not happening. I created the shape Id like for all of the things to be along the path, but I don;t know which method of creating a brush to use.
Also, how to make each part around the circle get lighter?
