get_value of a feature in IFeatureCursor - arcobjects

I'm trying to read the attribute "POSTCODE" of the features in IFeatureCursor. The FID was successful read but the "POSTCODE" was failed. The runtime error 'An expected Field was not found or could not be retrieved properly. Appreciate your advise. Paul
private void test2(IFeatureCursor pFeatc1)
{
IFeature feature = null;
IFields pFields;
int ctcur = 0;
while ((feature = pFeatc1.NextFeature()) != null)
{
pFields = feature.Fields;
int indxid = pFields.FindField("FID");
int indxpost = pFields.FindField("POSTCODE");
object valu = feature.get_Value(indxid);
string valupost = feature.get_Value(indxpost);
string aValu = Convert.ToString(valu);
Debug.WriteLine("FID: " + aValu + " Postcode: " + valupost);
ctcur++;
feature = pFeatc1.NextFeature();
}
MessageBox.Show("count cursor = " + ctcur);
}

I have modified the program and successfully read the feature attribute 'POSTCODE'. I have added IFeatureClass.Search(queryFilter, true) to search the feature again by FID and save in a cursor then use the 'feature.get_Value' to read the attribute. Please see my updated code below. Thanks.
private void test2(IFeatureCursor pFeatc1)
{
IMxDocument mxdoc = ArcMap.Application.Document as IMxDocument;
IMap map = mxdoc.FocusMap;
IFeatureLayer flayer;
IMaps pMaps = mxdoc.Maps;
for (int i = 0; i <= pMaps.Count - 1; i++)
{
map = pMaps.get_Item(i);
IEnumLayer pEnumLayer = map.get_Layers(null, true);
pEnumLayer.Reset();
ILayer pLayer = pEnumLayer.Next();
while (pLayer != null)
{
if (pLayer.Name == "AddrKey")
{
Debug.WriteLine("Layer: " + pLayer.Name);
flayer = (IFeatureLayer)pLayer;
IFeatureLayer pFeatureLayer = (IFeatureLayer)pLayer;
IFeatureClass pFeatureClass = pFeatureLayer.FeatureClass;
IFeature feature = null;
IFields pFields;
while ((feature = pFeatc1.NextFeature()) != null)
{
pFields = feature.Fields;
int indx = pFields.FindField("FID");
object valu = feature.get_Value(indx);
string sFID = Convert.ToString(valu);
IQueryFilter queryFilter = new QueryFilter();
queryFilter.WhereClause = ("FID = " + sFID);
Debug.WriteLine("FID: " + sFID);
queryFilter.SubFields = "POSTCODE";
int fieldPosition = pFeatureClass.FindField("POSTCODE");
IFeatureCursor featureCursor = pFeatureClass.Search(queryFilter, true);
while ((feature = featureCursor.NextFeature()) != null)
{
MessageBox.Show(feature.get_Value(fieldPosition));
}
feature = pFeatc1.NextFeature();
}
}
pLayer = pEnumLayer.Next();
}
}

Docx4j's legacy field processing does not parse IF fields: http://webapp.docx4java.org/OnlineDemo/ecma376/WordML/IF.html
If you need to do that, you'll need to write code to do the parsing.
An alternative would be to use OpenDoPE conditional content controls. With one of these, the content of the SDT is included only if the associated XPath evaluates to true.

error: Conditions must have a static type of 'bool'

I tried to make a calculator in flutter for the first time, but an error occur at the bool type that i don't understand. (on the "if" opertaion)
class _CalculatorAppState extends State<CalculatorApp> {
int? firstNum;
int? secondnum;
String? textToDisplay;
String? history = '';
String? res = '';
String? operation;
void btnOnClick(String btnVal){
print(btnVal);
if( btnVal == 'C'){
textToDisplay = '';
firstNum = 0;
secondnum = 0;
res= '';
} else if (btnVal == 'C'){
textToDisplay = '';
firstNum = 0;

} else if ( btnVal == '+'||

You're currently typing operation = 'x' which isnt valid syntax. You need a double '=', so:
if (operation == 'x') {
// do stuff
}
The equality operator is == not =.
At those lines listed you used = instead of ==.
And declare the variables as follows:
var firstNum = 0;
var secondnum = 0;
var textToDisplay = '';
var history = '';
var res = '';
var operation = '';

how to replace array object in flutter

if(_list.length != 0){
var shape;
var shapeCount;
var shapeCaratCount;
var shapeTotalAmount;
var details = new Map();
var temp = [Map()];
for(int l = 0 ; l <= _list.length; l++){
var list = _list[l];
if(temp.contains(list.shape)){
shapeCount += 1;
shapeCaratCount = shapeCaratCount + list.carat;
shapeTotalAmount = shapeTotalAmount + list.totalAmount;
details['Shape'] = list.shape;
details['pcs_count'] = shapeCount;
details['Carat_Count'] = shapeCaratCount;
details['total_amount'] = shapeTotalAmount;
print(details);
temp.add(details);
}else{
shapeCount = 0;
//shapeCaratCount = shapeCaratCount + list.carat;
shapeCaratCount = list.carat;
shapeTotalAmount = list.totalAmount;
details['Shape'] = list.shape;
details['pcs_count'] = shapeCount;
details['Carat_Count'] = shapeCaratCount.toString();
details['total_amount'] = shapeTotalAmount.toString();
print(details);
temp.add(details);
}
}
}
I want to replace array object of temp dictionary array.
so if any know how to do this please help i am new at flutter
this is my code please if any difficulty. please ask.

inserting into SQL via sqlbulk

hallo i have this sniped code like this:
public static void Put_CSVtoSQL_Adhesion()
{
bool IsFirst = true;
DataTable dt = new DataTable();
string line = null;
int i = 0;
try
{
string fileName = Path.Combine(HttpContext.Current.Server.MapPath(UploadDirectory), TheFileName);
using (StreamReader sr = File.OpenText(fileName))
{
while ((line = sr.ReadLine()) != null)
{
string[] data = line.Split(';');
if (data.Length > 0)
{
if (i == 0)
{
foreach (var item in data)
{
dt.Columns.Add(new DataColumn());
}
i++;
}
DataRow row = dt.NewRow();
row.ItemArray = data;
// Pour enlever la tete
if (!IsFirst) dt.Rows.Add(row);
IsFirst = false;
}
}
}
using (var connectionWrapper = new Connexion())
{
var connectedConnection = connectionWrapper.GetConnected();
using (SqlBulkCopy copy = new SqlBulkCopy(connectionWrapper.conn))
{
int CountColl = dt.Columns.Count;
copy.ColumnMappings.Add(0, 1);
copy.ColumnMappings.Add(1, 2);
copy.ColumnMappings.Add(2, 3);
copy.ColumnMappings.Add(3, 4);
copy.ColumnMappings.Add(4, 5);
copy.DestinationTableName = "cotisation";
copy.WriteToServer(dt);
}
}
}
catch (Exception excThrown)
{
throw new Exception(excThrown.Message);
}
}
this code work well, but now i have more than 60 column, should i type manualy from 1 to 60 column or there are another methode ?
copy.ColumnMappings.Add(0, 1);
copy.ColumnMappings.Add(1, 2);
copy.ColumnMappings.Add(2, 3);
copy.ColumnMappings.Add(3, 4);
copy.ColumnMappings.Add(4, 5);
...until 60 column ?
the column is all the same i just shifted 1 column, because the first one is autoincremented column as an ID
Write a loop?
for (int i = 0; i < dt.Columns.Count - 1; i++)
{
copy.ColumnMappings.Add(i, i + 1);
}
