I am developing an application in .NET to solve VRP, without using ArcGIS Server, but I can not find a complete sample code, I used other samples such as routesolver and get help from them, but I faced Exception in INASolver.Solve that shows I didn't load NAClasses correctly, I will be really thankfull if you could help me.Please!!!
I get COMExecption on the line : INASolver.Solve(...), details:Invalid input in NAClass
my code:
IAoInitialize pAoInitialize = new AoInitializeClass();
pAoInitialize.Initialize(esriLicenseProductCode.esriLicenseProductCodeArcView);
pAoInitialize.CheckOutExtension(esriLicenseExtensionCode.esriLicenseExtensionCodeNetwork);
IWorkspaceFactory ipWorkspaceFactory = new ShapefileWorkspaceFactoryClass();
m_pWorkspace = ipWorkspaceFactory.OpenFromFile(SHAPE_WORKSPACE, 0);
IFeatureWorkspace pFWorkspace = m_pWorkspace as IFeatureWorkspace;
IWorkspaceExtensionManager pWorkspaceExtensionManager = m_pWorkspace as IWorkspaceExtensionManager;
UID pUID = new UIDClass();
pUID.Value = "esriGeoDatabase.NetworkDatasetWorkspaceExtension";
IDatasetContainer2 pDatasetContainer2;
pDatasetContainer2 = pWorkspaceExtensionManager.FindExtension(pUID) as IDatasetContainer2;
m_pNetworkDataset = pDatasetContainer2.get_DatasetByName(esriDatasetType.esriDTNetworkDataset, NETWORK_DATASET) as INetworkDataset;
INALayer pNALayer = CreateVRPAnalysisLayer("Vehicle Routing Problem", m_pNetworkDataset);
String INPUT_DEPOTS = "DistributionCenters";
String INPUT_ORDERS = "Stores";
INAContext pNAContext;
pNAContext = pNALayer.Context;
INAContextEdit vrpNAContextEdit = pNAContext as INAContextEdit;
vrpNAContextEdit.Bind(pNALayer.Context.NetworkDataset, null);
m_pInputFClass = pFWorkspace.OpenFeatureClass(INPUT_DEPOTS);
ICursor InputDepotsCursor = m_pInputFClass.Search(new QueryFilterClass(), false) as ICursor;
LoadAnalysisLayer("Depots", pNAContext, InputDepotsCursor);
m_pInputFClass = pFWorkspace.OpenFeatureClass(INPUT_ORDERS);
ICursor InputOrdersCursor = m_pInputFClass.Search(new QueryFilterClass(), false) as ICursor;
LoadAnalysisLayer("Orders", pNAContext, InputOrdersCursor);
IMap vrpMap = axMapControl1.Map;
ITable routesInputTable = GetStandaloneTable("Vehicles", vrpMap).Table;
ICursor InputRoutesCursor = routesInputTable.Search(new QueryFilterClass(), true) as ICursor;
LoadAnalysisLayer("Routes", pNAContext, InputRoutesCursor);
INASolver pSolver;
pSolver = pNAContext.Solver;
INAVRPSolver vrpSolver = pSolver as INAVRPSolver;
vrpSolver.GenerateInternalRouteContext = true;
vrpSolver.DefaultDate = DateTime.Today;
pSolver.Solve(pNAContext, new GPMessagesClass(), new CancelTrackerClass());
private void LoadAnalysisLayer(string ClassName, INAContext context, ICursor cursor)
{
INAClass pNAClass;
pNAClass = context.NAClasses.get_ItemByName(ClassName) as INAClass;
INAClassFieldMap pNAClassFieldMap = new NAClassFieldMapClass();
pNAClassFieldMap.set_MappedField("Name", SHAPE_INPUT_NAME_FIELD);
INAClassLoader pNALoader = new NAClassLoaderClass();
pNALoader.Locator = context.Locator;
pNALoader.NAClass = pNAClass;
pNALoader.FieldMap = pNAClassFieldMap;
int rowsInCursor = 0;
int rowsLocated = 0;
pNALoader.Load(cursor, new CancelTrackerClass(), ref rowsInCursor, ref rowsLocated);

line = "==XXXT08746=05/01/09 15:13 112 4 IT 0:01'22 0 #2 ";
string Duration = line.Substring(64, 9).Replace("#","[#]");
int s = Convert.ToInt32(Duration.Substring(1, 2));
int s = Convert.ToInt32(Duration.Substring(1, 2));
int y = Convert.ToInt32(Duration.Substring(3, 2));
int l = Convert.ToInt32(Duration.Substring(6, 2));
int NDura = s + y + l;
---->>>> Error System.FormatException: Input string was not in a correct format.
So what should I do with this ?

This is very silly mistake which u can trace it out.

In above four lines, check wat is the value of (Duration.Substring());
it may be null or may not be in format to convert to integer.

I don't understand how the code has got compiled!

Finally what is the value you are expecting in the
Duration string ? Do the debug and verify if it has the desired value or not...

The quick answer:
int s = Convert.ToInt32(Duration.Substring(1, 1));
Why?
Try changing your code to this:
String line = "==XXXT08746=05/01/09 15:13 112 4 IT 0:01'22 0 #2 ";
string Duration = line.Substring(64, 9).Replace("#", "[#]");
string a = Duration.Substring(1, 2);
string b = Duration.Substring(3, 2);
string c = Duration.Substring(6, 2);
int s = Convert.ToInt32(a);
int y = Convert.ToInt32(b);
int l = Convert.ToInt32(c);
int NDura = s + y + l;
You will discover that duration equals " 0:01'22 " and so the string you are trying to parse is "0:" - thats why you keep getting the error.
Also this line:
string Duration = line.Substring(64, 9).Replace("#", "[#]");
Is kind of wierd as the Replace has no effect - as I mentioned Duration == " 0:01'22 ". No "#" there...

Thank you
I 've got it even if I've made alot of mistake like u said
now is my code
string Duration = line.Replace("'", "[']");
string LineOO = line.Replace("#", "[#]");
string Date = line.Substring(12, 8);
if (line.Substring(11, 1) == "=")
{
string Time = line.Substring(21, 5);
string Linein = line.Substring(27, 10);
string Lineout = LineOO.Substring(38, 1);
if ((string.Compare(Lineout, "0") > 0 || string.Compare(Lineout, "0") == 0) && (string.Compare(Lineout, "9") < 0 || string.Compare(Lineout, "9") == 0))
{
string Number = line.Substring(40, 20);
string Status = line.Substring(61, 3);
string NDuration = Duration.Substring(64, 10);
string b = NDuration.Substring(3, 2);
string c = NDuration.Substring(6, 2);
int y = Convert.ToInt32(b);
int l = Convert.ToInt32(c);
int NDura = y + l;
string Cost = line.Substring(75, 3);
string Detail = line.Substring(79, 2);
string Network = line.Substring(82, 8);
and it work
Thx

There is still room for some improvement. 
Instead of getting a one character string, you can get a character. You can change this:
if (line.Substring(11, 1) == "=")
to:
if (line[11] == '=')
You can use the >= operator instead of doing both > and == comparisons. You can change this:
if ((string.Compare(Lineout, "0") > 0 || string.Compare(Lineout, "0") == 0) && (string.Compare(Lineout, "9") < 0 || string.Compare(Lineout, "9") == 0))
to:
if (string.Compare(Lineout, "0") >= 0 && string.Compare(Lineout, "9") <= 0)
However, you can use a char instead of a one character string there too:
char Lineout = Line00[38];
if (Lineout >= '0' && Lineout <= '9')
or simply:
if (Char.IsDigit(Line00, 38))
Despite everything, the person most likely to be fooling you next is yourself.

Wowwww
It's so short and simply but I've never knoww.
thx very much
Code is ok but I 've just want to know how to decrease time to do it coz I have 10,100 data and it took a long time.

I while back I wrote this method that you can use to replace Int32.Parse, and that is about ten times faster. That could help to speed up it a bit.
public static int ParseInt32(string text) {
long value = 0;
long sign = 1;
bool first = true;
foreach (char c in text) {
if (c >= '0' && c <= '9') {
value = value * 10 + c - '0';
} else if (c == '-' && first) {
sign = -1;
} else {
throw new FormatException();
}
first = false;
}
value *= sign;
if (value < int.MinValue || value > int.MaxValue) throw new OverflowException();
return (int)value;
}
Despite everything, the person most likely to be fooling you next is yourself.

i need to get customer information from a java web service my client app is a C# . instead of calling the web service several times i want to get customer object , to do this i use a customer xsd and generated two classes one for c# and other of java ,then i added those classes to relevant party, in the java web service i create a customer object and fill it with info and send to c#, but in C3 it say that the passed object can't be implicitly cast ,any idea to solve this .

Whenever you modify the java code you need to update the references(proxy classes) in C# and then compile it.
I don't understand your problem exactly but hope this helps you.

I have my form currently set up with a treeview and a listview. The treeview shows all the folders with check boxes and the listview shows the files within the selected folder on the treeview.
I am trying to create a backup program which can successfully backup selected files/folders and successfully restore these at a later time.
My question is if anyone can give me any ideas on how to approach this? I'm thinking I would use an output textfile showing which files/folders were backed up and their fullpath?

Hi,
How do i select the whole listViewItem line (all the subitems of an item) when trying to copy it in the clipboard?
I have a listView with 5 columns. When i try to select 1 row it only selects the first column value not the whole row..
any ideas?
Regards,
Alex

Assuming this is a Windows Forms ListView.
I don't know if it will make any difference to a drag-drop operation, but ListView has a FullRowSelect property, which er... well it does what it says on the tin.

Set the FullRowSelect property to true.
for example,
listView1.FullRowSelect = true;
|
|
|
|
|
Check the properties.
listView1.FullRowSelect = true;

Hi people,
I have the a form in my application where the user can enter a data and time and then save it to a Mysql database. but I get a FormatExeption saying "Input string was not in a correct format" How can I convert from .net datatime datatype to Mysql database type ?
Heres my method for inserting a row that contains a datetime datatype
private void shiftInsertNewRow()
{
conn = new MySqlConnection
("datasource=localhost;username=admin;password=student;database=hospital");
conn.Open();
MySqlCommand command = new MySqlCommand
("insert into shifts(ShiftID, Starttime, Endtime, WardID, NurseID) select ?ShiftID, ?Starttime, ?Endtime, ?WardID, ?NurseID", conn);
command.Parameters.Add(new MySqlParameter("?ShiftID", MySqlDbType.Int32));
command.Parameters.Add(new MySqlParameter("?Starttime", MySqlDbType.Datetime));
command.Parameters.Add(new MySqlParameter("?Endtime", MySqlDbType.Datetime));
command.Parameters.Add(new MySqlParameter("?WardID", MySqlDbType.Int32));
command.Parameters.Add(new MySqlParameter("?NurseID", MySqlDbType.Int32));
command.Parameters[0].Value = shiftidTextBox.Text;
command.Parameters[1].Value = startTimeTextBox.Text;
command.Parameters[2].Value = endTimTextBox.Text;
command.Parameters[3].Value = wardShiftidTextBox.Text;
command.Parameters[4].Value = wardNameTextBox.Text;
command.ExecuteNonQuery();
conn.Close();
}
any help would be greatly appreciated

I would imaging it would work the same was as SQL Server. Convert the text to a DateTime object, then pass the DateTime object as a parameter.

|

well I tried to assign a DateTime object to Value but it didnt work either
command.Parameters[1].Value = DateTime.Now;
command.Parameters[2].Value = DateTime.Now;

Define "didn't work". Exactly how did it not work? Did it cause an exception? Did it fail to compile? Did it run but the result was wrong? What?

it threw the same format exception again.
|
|
|
|
|
now define 'it'
exceptions hold a lot of information, including exact line numbers. Which statement throws what?
the quality and detail of your question reflects on the effectiveness of the help you are likely to get

During runtime when I execute shiftInsertNewRow() method I get a Format exception at this line:
command.ExecuteNonQuery() that says input string was not in a correct format.
