I am strugglying with a problem that is to access the reference of the end point of a pipe curve to then create a dimension in the model, by the method doc.Create.Dimension().I already tried to use the Curve.EndPointReference(int index) method but it returns only null value. Can anyone help how to access this information ?

Fair59's answer:
You probably are using the LocationCurve to find the reference. You need to use the "reference" Curve/Line that is part of the Element.Geometry.
Selection sel = this.ActiveUIDocument.Selection;
Element elem = doc.GetElement(sel.GetElementIds().FirstOrDefault());
Options opt = new Options();
opt.ComputeReferences = true;
opt.IncludeNonVisibleObjects = true;
opt.View = doc.ActiveView;
Reference ptRef =null;
foreach( var geoObj in elem.get_Geometry(opt) )
{
Curve cv = geoObj as Curve;
if (cv==null) continue;
ptRef = cv.GetEndPointReference(0);
}
if (ptRef!=null)
{
TaskDialog.Show("debug",ptRef.ConvertToStableRepresentation(doc));
}
I think you should try something like
yourPipe.Location.Curve.GetEndPoint(1)
This will give you the XYZ object of the end point of your curve.

I am iterating over a collection of data, in my case, an array of objects. Here is a sample of 2 data points from it:
{
violation_id: '211315',
inspection_id: '268804',
violation_category: 'Garbage and Refuse',
violation_date: '2012-03-22 0:00',
violation_date_closed: '',
violation_type: 'Refuse Accumulation' },
{
violation_id: '214351',
inspection_id: '273183',
violation_category: 'Building Conditions',
violation_date: '2012-05-01 0:00',
violation_date_closed: '2012-04-17 0:00',
violation_type: 'Mold or Mildew' }
I need to create a new array of objects from this, one for each "violation_category" property. If Violation category already exists in the new array I am creating, i simply add the information to that existing category object (instead of having two "building conditions" objects for example, I would just add to an existing one).
However, I am having trouble assigning to the existing object if the current one exists (it's easy to check if it does not, but not the other way around). This is what am attempting to do currently:
if (violationCategory.uniqueCategoryName) {
violationCategory.uniqueCategoryName.violations = results[i].violation_id;
violationCategory.uniqueCategoryName.date = results[i].violation_date;
violationCategory.uniqueCategoryName.closed =
results[i].violation_date_closed;
} else {
category.violations = results[i].violation_id;
category.date = results[i].violation_date;
category.closed = results[i].violation_date_closed;
violationCategory.push(category);
}
In first condition, if this category (key) exists, I simply add to it, and in the second condition, this is where I am struggling. Any help appreciated. Thanks guys.
Just add an empty object to the key if there no object there :
violationCategory.uniqueCategoryName = violationCategory.uniqueCategoryName || {};
And only then, add the data you want to the object.
violationCategory.uniqueCategoryName.violations = results[i].violation_id;
violationCategory.uniqueCategoryName.date = results[i].violation_date;
violationCategory.uniqueCategoryName.closed =
results[i].violation_date_closed;
No condition needed.
Good luck!
Assuming that you have an input variable which is an array of objects, where the objects are looking like the objects of the question, you can generate your output like this:
var output = {};
for (var item of input) {
if (!output[item.violation_category]) output[item.violation_category] = [];
output[item.violation_category].push(item);
}
Of course you might customize it like you want.
.NET 4.5, C#, Npgsql 3.1.0
I have a query which retrieves a Postgis geometry field - the only way I could see of doing this was:
public class pgRasterChart
{
...
public NpgsqlTypes.PostgisGeometry GEOMETRY;
...
}
...
NpgsqlDataReader reader = command.ExecuteReader();
try
{
while (reader.Read())
{
pgRasterChart chart = new pgRasterChart();
chart.GEOMETRY = (PostgisGeometry) reader.GetValue(21);
...
This functions but I need to get at the coordinates of the GEOMETRY field and I can't find a way of doing that? I want to use the coordinates to display the results on an OpenLayers map.
Any answers most gratefully received. This is my first post so my apologies if the etiquette is clumsy or question unclear.
Providing another answer because the the link above to the documentation for PostGisTypes is now broken.
PostGisGeometry is an abstract base class that does not contain anything more exiting than the SRID. Instead, you want to cast the object obtained by your datareader to the appropriate type (any of the following):
PostGisLineString
PostGisMultiLineString
PostGisMultiPoint
PostGisMultiPolygon
PostGisPoint
PostGisPolygon
These classes have ways of getting to the coordinates.
eg:
...
NpgsqlDataReader reader = command.ExecuteReader();
try
{
while (reader.Read())
{
var geom = (PostgisLineString) reader.GetValue(0);
var firstCoordinate = geom[0]; // Coordinate in linestring at index 0
var X = firstCoordinate.X;
var Y = firstCoordinate.Y;
...
As you can see here
https://github.com/npgsql/npgsql/blob/dev/src/Npgsql.LegacyPostgis/PostgisTypes.cs
PostgisGeometry types are a set of xy pairs.
For example, a linestring is an array of points, a polygon is an array of rings and so on..
You could traverse those structures and get the coordinates.
However, if you just want to display geometries using openlayers, I suggest you to use the wkt format.
You should change your query, selecting st_astext(geometry) instead of geometry, than treat the result as a string and give it back to OpenLayers.
Then use OpenLayers.Geometry.fromWKT to parse the WKT into an OpenLayers.Geometry
I have added a custom property to my workbook object like:
((XSSFWorkbook)workBook).getProperties().getCustomProperties().addProperty("fileNameSuffix" , "testName");
Now how can I read it back again.
Why there is no such method as getProperty(String key) ?
Do you mean like the method POIXMLProperties.CustomProperties.getProperty(String)? I think that should do what you want. Well, assuming you're on a new enough version of Apache POI to have it at least!
However, do note that it returns a CTProperty object, which is fairly low-level, and doesn't have an explicit type on it. You'll have to call the various isSetXXX methods to work out what kind it is, then getXXX to get the value.
There's an example of how to do that in POIXMLPropertiesTextExtractor
I figure a way to do it, but I do not really like it this way
List<CTProperty> customProperties = workBook.getProperties().getCustomProperties().getUnderlyingProperties().getPropertyList();
String fileNameSuffix = "";
for(int i = 0 ; i < customProperties.size() ; i++) {
CTProperty property = customProperties.get(i);
if (customProperties.get(i).getName().equals("testName"))
fileNameSuffix = property.getLpwstr(); // getLpwstr() will return the value of the property
}
How would I go about changing the default MCheckBox state text (currently I/0) to, for example, YES/NO or ON/OFF?
Mr. Daniel Kurka is the author for all the widget classes in MGWT. If the look & feel is not
fulfilling our requirement, We can edit those classes and rewrite them according to our requirement.Because they are open source. I done this on many classes like CellList,FormListEntry and MCheckBox. code for ON/OFF instead of I/O
public MyOwnCheckBox(CheckBoxCss css) {
this.css = css;
css.ensureInjected();
setElement(DOM.createDiv());
addStyleName(css.checkBox());
onDiv = DOM.createDiv();
onDiv.setClassName(css.on());
onDiv.setInnerText("ON");
getElement().appendChild(onDiv);
middleDiv = DOM.createDiv();
middleDiv.setClassName(css.middle());
Element middleContent = DOM.createDiv();
middleContent.setClassName(css.content());
middleDiv.appendChild(middleContent);
getElement().appendChild(middleDiv);
offDiv = DOM.createDiv();
offDiv.setClassName(css.off());
offDiv.setInnerText("OFF");
getElement().appendChild(offDiv);
addTouchHandler(new TouchHandlerImplementation());
setValue(true, false);
}
Write a new class like MyOwnCheckBox.just copy the code in MCheckBox and paste in your class MyOwnCheckBox, find and replace the MCheckBox with MyOwnCheckBox in the code(change constructor's name). do the following changes.
onDiv.setInnerText("ON");
offDiv.setInnerText("OFF");
and finally create object to MyOwnCheckBox rather MCheckBox, it'll shows MCheckBox with ON/OFF.
Right now there is no way to do that, but there is no real reasons that checkbox does not implement HasText other than we might need to update the css so that big text will not break the layout.
If you think mgwt should implement this go and vote for this issue: http://code.google.com/p/mgwt/issues/detail?id=171
Well, an easy way to accomplish the same thing, without creating a new class that mimics MCheckBox, is to do something like the code below:
CheckBoxCss css = MGWTStyle.getTheme().getMGWTClientBundle().getCheckBoxCss();
String offClass = css.off();
String onClass = css.on();
NodeList<Node> checkBoxElems;
mIsSingleSkuBox = new MCheckBox(css);
checkBoxElems = mIsSingleSkuBox.getElement().getChildNodes();
for( int i = 0; i < checkBoxElems.getLength(); i++ )
{
Element openElem = (Element) checkBoxElems.getItem(i);
String className = openElem.getClassName();
if( className.equals( offClass))
{
openElem.setInnerText("No" );
}
else if( className.equals( onClass))
{
openElem.setInnerText("Yes" );
}
}
It will probably have space problems with anything longer than 3 characters, but it works consistently with "Yes" and "No" for me.
Today, I'm having a problem is after I had created a Calculated field. It seems there is no way to add AllContentTypes. And the DefaultView, maybe I can handle this. And I also saw this method:
spList.Fields.AddFieldAsXml(spFieldUser.SchemaXml, True, SPAddFieldOptions.AddToAllContentTypes);
But in this case, I'm not sure I can use it or not. Because my code is:
//SPField tempSPField = spList.Fields.CreateNewField(createSPColumnObject.ColumnType, createSPColumnObject.ColumnName);//We can not use this code line for creating Calculated (there is no constructor for this)
SPFieldCollection collFields = spList.Fields;
string strSPFieldCalculatedName = collFields.Add(createSPColumnObject.ColumnName, SPFieldType.Calculated, false);
if (createSPColumnObject.IsAddedToDefaultView)
{
SPView spView = spList.DefaultView;
spView.ViewFields.Add(strSPFieldCalculatedName);
spView.Update();
}
SPFieldCalculated spFieldCalculated = null;
//
spFieldCalculated = (SPFieldCalculated)collFields[createSPColumnObject.ColumnName];
spFieldCalculated.ShowInDisplayForm = true;
//spFieldCalculated.ShowInEditForm = true;
spFieldCalculated.ShowInListSettings = true;
//spFieldCalculated.ShowInNewForm = true;
spFieldCalculated.ShowInViewForms = true;
//
spFieldCalculated.Description = createSPColumnObject.ColumnDescription;
spFieldCalculated.Formula = string.Format(#"={0}",createSPColumnObject.CalcFormula);
spFieldCalculated.Update();
//spList.Fields.AddFieldAsXml(spFieldCalculated.SchemaXml, createSPColumnObject.IsAddedToDefaultView, SPAddFieldOptions.AddToAllContentTypes);// also use this code line because we will get an exception with a duplicate column ID.
spFieldCalculated.OutputType = SPFieldType.Text;
spList.Update();
I totally created a Calculated column but how can I add it to allcontent types ? everybody could help me out this ? BTW, to the DefaultView, I did like the above is right ? Could eveybody let me know this ?
I just worry about everybody get misunderstanding ? Or review with missing code. So could everybody please to take a look on my code clearly ? Thanks all.
Many thanks, :)

I'm not sure if i fully understand what you are trying to do however i may be able to shed some light on some parts of what you are trying to do.
When you create your field does it then appear in your site actions -> site settings -> Site columns. If so you have created this correctly. If it doesn't there are hundreds of examples of how to do this if you search google.
Once you have your field create you then need to consider which content types you want to add it to. Once you have these content types you then have to add something called a field link to the Content type.
This isn't my code i have picked it off the web but this should do what you require.
SPContentType ct = web.ContentTypes[contentType];
ct.FieldLinks.Add(new SPFieldLink(field));
ct.Update();
