what does it mean Object reference not set to an instance of an object in the line below?
case "S Connected":
List dd6 = new List(textBox1.Text);
**dd6.textBox2.Text = id.ToString();**
dd6.ShowDialog();
Thanks, guys. The first case works perfectly, the W connected and the S connected retrieve the error:
private void dataGridView1_CellDoubleClick(object sender, DataGridViewCellEventArgs e)
{
var id = dataGridView1.CurrentRow.Cells["Id"].Value;
var BBB = dataGridView1.CurrentRow.Cells["Connected"].Value;
string idd = id.ToString();
string BBB2 = BBB.ToString();
textBox1.Text = id.ToString();
switch (BBB2)
{
case "Standalone":
ListStandalone dd = new ListStandalone(textBox1.Text);
dd.textBox2.Text = id.ToString();
dd.ShowDialog();
break;
case "W Connected":
ListW da2 = new ListW(textBox1.Text);
da2.textBox2.Text = id.ToString();
da2.ShowDialog();
break;
case "S Connected":
ListS dd6 = new ListS(textBox1.Text);
dd6.textBox2.Text = id.ToString();
dd6.ShowDialog();
break;
case "Retail":
PrintRetail dd4 = new PrintRetail(textBox1.Text);
dd4.Show();
break;

My requirement is to create a customer location part of downloading order from 3rd party shopping cart.
I have tried this below code and It is not saving any location and also not raising any error.
private static void CreateCustomerLocation(Customer cust, string locationcode, OrderDTO ord, OrderDownloadActivityEntry grp)
{
try
{
LocationMaint graph = CustomerLocationMaint.CreateInstance<CustomerLocationMaint>();
SelectedLocation loc = new SelectedLocation();
loc.BAccountID = cust.BAccountID;
loc.LocationCD = locationcode;
loc.Descr = ord.CustomerLocationName;
loc.IsContactSameAsMain = false;
loc.IsAddressSameAsMain = false;
graph.Location.Insert(loc);
Contact contact = new Contact();
contact.Attention = ord.OrderCustomerContactName;
contact.Phone1 = ord.OrderCustomerContactPhone;
contact.DisplayName = ord.CustomerLocationName;
contact.LastName = ord.OrderCustomerContactName;
contact = graph.Contact.Update(contact);
Address address = new Address();
address.AddressLine1 = ord.OrderShippingLocationAddress1;
address.AddressLine2 = ord.OrderShippingLocationAddress2;
address.City = ord.OrderShippingLocationCity;
address.State = ord.OrderShippingLocationState;
address.PostalCode = ord.OrderShippingLocationZip;
address.CountryID = "US";
contact = graph.Contact.Update(contact);
address = graph.Address.Update(address);
loc.DefAddressID = address.AddressID;

graph.Save.Press();
}
catch(Exception e)
{
grp.AddLogData(SessionID, "Create Location", "Create Location falied", null, null, e.StackTrace);
}
}
I am not able to figure out where i am making mistake. any suggestion for this issue?

CARAccountLocationID is the LocationID of the MAIN location for a given BAccount/Customer. It is used by the business logic when setting GLAccounts.SameAsDefaultLocationS on screen AR303020.
I've seen the "'CARAccountLocationID' cannot be empty." error when creating a location without first setting the Customer.
The resolution was to first set the customer, then set SameAsDefaultLocationS, then set the rest of the fields.
In the screen API order of operations matters.
In your case you might need to directly set loc.CARAccountLocationID to the LocationID of the customer's MAIN location.
I am trying to insert a new Activity for Case. The code which I have written executes without any error but it even does not inserts any Activity. Let me know if I am missing anything.
Here is the code
CRActivity actiCloud9 = new CRActivity();
actiCloud9.Type = "N"; // Note
actiCloud9.Subject = current.Summary;
actiCloud9.Body = current.Description;
actiCloud9.UIStatus = current.Status;
actiCloud9.StartDate = current.StartDate;
actiCloud9.IsPrivate = true; // current.IsInternal;
actiCloud9.RefNoteID = Base.CaseCurrent.Current.NoteID;
Base.Activities.Cache.Insert(actiCloud9);
Try this.
[PXOverride]
public void Persist(Action del)
{
if ((Base.Case.Cache.GetStatus(Base.Case.Current) == PXEntryStatus.Inserted || Base.Case.Cache.GetStatus(Base.Case.Current) == PXEntryStatus.Updated))
{
CRActivityMaint objGraph = PXGraph.CreateInstance<CRActivityMaint>();
CRActivity actiCloud9 = new CRActivity();
actiCloud9.Type = "N"; // Note
actiCloud9.Subject = "Subject";
actiCloud9.Body = "Body";
actiCloud9.RefNoteID = Base.CaseCurrent.Current.NoteID;
objGraph.Activities.Cache.Insert(actiCloud9);
objGraph.Actions.PressSave();
}
del();

I am trying to return an object array from my database but can't get the call correct or the return object[s].
In the example below I just return an empty String trying to get this working. The listings[cnt] are being filled properly but I'm not sure how to make the call and return the Objects?
I am making 2 different calls to new Houses in getData() and that doesn't seem right either.
Houses[] listings = new Houses[cnt]; // Seems like I need this to initialize the array to a certain size.
listings[cnt] = new Houses(z,a,b,c,d,e,f,g,h); // Then I fill the Object with variables.
then return listings somehow.
// ??? How do I set it up so that I get an array of objects back?
// I am making the call from MainActivity here
myHelper = new GrumpyDB(this);
String h = new String();
h = myHelper.getData();
public String getData() {

Cursor cursor = db.query(myHelper.TABLE_NAME_LOCATION, columns, null, null, null, null, null);
int cnt = cursor.getCount();
Houses[] listings = new Houses[cnt];
cnt = 0;
while (cursor.moveToNext()) {

Change your method signature to
public Houses[] getData() {
I have assigned a text from a txt file to three attributes, but whenever I call any of those attributes with a Get Method to another class, the value displayed is "null".
Furthermore, I have confirmed that these values are displayed in the method leerArchivo (whenever I use a println for m_linea1-2-3).
Please Help.
public class ArchivoCasillas
{
String m_linea1;
String m_linea2;
String m_linea3;
public void crearArchivo()
{
try
{
FileWriter fw = new FileWriter("ReglasDelTablero.txt");
BufferedWriter bw = new BufferedWriter(fw);
PrintWriter pw = new PrintWriter(fw);
bw.write("<7,0> , <0,0>");
bw.newLine();
bw.write("<4,1> , <7,2> | <2,7> , <5,5> | <1,2> , <7,4> | <0,4> , <2,5>");
bw.newLine();
bw.write("<7,7> , <3,6> | <6,4> , <3,5> | <4,0> , <2,1> | <2,4> , <0,3>");
bw.close();
}
catch(IOException e)
{
System.out.println("error");
}
}
public void leerArchivo()
{
String linea;
int i = 1;
try
{
FileReader fr = new FileReader("ReglasDelTablero.txt");
BufferedReader br = new BufferedReader(fr);
Tablero serpientesEscaleras = new Tablero();
while( (linea = br.readLine() ) != null)
{
switch(i)
{
case 1: m_linea1 = linea;
break;
case 2: m_linea2 = linea;
break;
case 3: m_linea3 = linea;
break;
}
i++;
}
br.close();
}
catch(IOException e)
{
}
}
public String getM_linea1()
{
return m_linea1;
}
}
Problem solved. It was a conceptual problem on my part. I created an Object in another class, but I never called the leerArchivo method with that object, therefore, the value of the attributes was null. Leaving an answer in case it's useful for someone in the future, as I didn't get a reply.

try passing latitude as 33.4965 & longitude as -112.205
i'm getting an exception object reference to invalid object in the line
**typename = xn["type"].InnerText;**
when i debug step by step there is no such attribute like ["type"]
Also there are some other lingual character why?
How could i resolve this issue.
I'm not familiar with c# and Im not sure if your code is correct at all(e.g. types is not an attribute, it's an elementNode).
Assuming that your code is correct and you can select nodes by using node['nameOfChildNode'] , when you inspect the XML-File: http://maps.googleapis.com/maps/api/geocode/xml?latlng=33.4965,-112.205&sensor=false you will see that there are address_components with 2 <type>'s and also address_components without any <type> .
I guess your code breaks not at the missing <type>, it breaks when you try to access a property(InnerText) of the missing <type>.
What you can do: use selectSingleNode to select the <type> and when it returns null implement a fallback or leave the further processing.
http://maps.googleapis.com/maps/api/geocode/json?latlng=33.4965%20,%20-112.205&sensor=false
returns
{
"results" : [],
"status" : "ZERO_RESULTS"
}
Therefore
XmlNode element = doc.SelectSingleNode("//GeocodeResponse/status");
if (element.InnerText == "ZERO_RESULTS")
{
return ("No data available for the specified location");
}
is not catching ZERO_RESULTS.
I am not familiar with C# so I cannot help further.
