Change values in HAMMER with WaterObjects.NET

Question

Hello, I've been trying to change the operational (Transient, Valve) Pattern in miy HAMMER project using WO.NET, but I just have been able to see the information, but not to modify anything. I've been looking everywhere in the Hydraulics and Hydrology Forum (because I don't have acces to BDN) and I found this post: 
 https://communities.bentley.com/products/hydraulics___hydrology/w/hydraulics_and_hydrology__wiki/28467.using-waterobjects-net-for-sewercad 
 The problem is that at the end they doesn't explain how to edit the values. I already read the WaterObjects.NET Programming Guide, but I couldn't find something useful. 
 My method I'm building to change the values: 
 public void ChangeValveClosure(int ID_CURVE, TorontoProject project) { ISupportElementManager CurveSet = project.DomainDataSet.SupportElementManager((int)SupportElementType.IdahoPatternElementManager); IUnitizedField CurveField = CurveSet.SupportElementField(StandardFieldName.TransientValveCurve_RelativeClosure) as IUnitizedField; IUnitizedField CurveFieldT = CurveSet.SupportElementField(StandardFieldName.TransientValveCurve_TimeFromStart) as IUnitizedField; //show values IModelingElement CurveElement = CurveSet.Element(ID_CURVE); FieldCollection Fields = CurveElement.Manager.SupportedFields(); IField ClosureCurv = Fields[32]; CollectionFieldListManagerBase F = (CollectionFieldListManagerBase)ClosureCurv.GetValue(ID_CURVE); FieldCollection Fields2 = F.SupportedFields(); IField TimeCurve = Fields2[0]; IField ClosureCurve = Fields2[1]; IDictionary TimeValues = TimeCurve.GetValues(); IDictionary ClosureValues = ClosureCurve.GetValues(); } 
 What am I missing? I don't know what else to do. 
 Im thankfull with any help, 
 Juan Sebastian.

Hi Juan,

You were actually pretty close but not quite there. Here is a modified version of your method. Note the two additional parameters that were added. Comments were also added to help make it clearer on what is going on.

If you have any questions, just ask.

public void ChangeValveClosure(int ID_CURVE, TorontoProject project,
double[] timeFromStart, double[] relativeClosure)
{
//Two new parameters were added to this method - timeFromStart and relativeClosure.

ISupportElementManager patternManager =
project.DomainDataSet.SupportElementManager((int)SupportElementType.IdahoPatternElementManager);

IEditField transientValveCurveField =
patternManager.SupportElementField(StandardFieldName.TransientValveCurve) as IEditField;
ICollectionFieldListManager cflm = (ICollectionFieldListManager)transientValveCurveField.GetValue(ID_CURVE);

IUnitizedField CurveField = cflm.Field(StandardFieldName.TransientValveCurve_RelativeClosure) as IUnitizedField;
IUnitizedField CurveFieldT = cflm.Field(StandardFieldName.TransientValveCurve_TimeFromStart) as IUnitizedField;

//This loop is just to get any existing values and write them out to the console window. This is not required.
for(int i = 0; i < cflm.Count; ++i)
{
double T = CurveFieldT.GetDoubleValue(i);
double C = CurveField.GetDoubleValue(i);

Console.WriteLine(T.ToString() + ", " + C.ToString());
}

//Check to make sure that the two arrays have the same number of items and they have more than one item
//to add to the pattern.
if(timeFromStart.Length == relativeClosure.Length && timeFromStart.Length > 0)
{
//To replace the values in the curve, you need to delete the existing rows and add new ones.
while(cflm.Count > 0)
cflm.Delete(0);

for(int i = 0; i < timeFromStart.Length; ++i)
{
int rowID = cflm.Add();
((IEditField)CurveFieldT).Setvalue(rowID, timeFromStart[i]);
((IEditField)CurveField).SetValue(rowID, relativeClosure[i]);
}

//Make sure you set the collection back to the collection field so it is stored in the database correctly.
transientValveCurveField.SetValue(ID_CURVE, cflm);
}
}

Hi Juan, 
 
I'm pretty sure I know what the problem is. 
 
Try the following. 
 
1. Create a new Form that inherits from System.Windows.Forms.Form (this is the default). Implement IUserInterface which is in Haestad.Framework.Application. Name the form UserInterfaceForm. 
 
The Open and ModelessFormClosing methods can be "no-op". Just remove the default exception that is there. For the OwnerWindow property, return "this" (no quotes). 
 
After creating the TorontoApplicationModel (I'm making the assumption that you are), create a new instance of your UserInterfaceForm. Pass this into the method SetCOMUserInterface on the instance of TorontoApplicationModel. 
 
Once you do that the call to ComputeHammer should start to work.
