Error msg conveying that a number is invalid because of Two dots within a real number in c#
Anyone can please help me
|

Help you with what? All you've given us is a statement that doesn't make any sense and no context information to work with. We have no idea what you're doing, what your code is doing, what you expect it to do, what it's actually doing, any error messages you're getting, ..., absolutely NOTHING to work with.
You've basically walked into a room with a bunch of people who don't know you and said "Error msg conveying that a number is invalid because of Two dots within a real number in c#" and then walked out of the room. Everyone in the room is now thinking "Who the hell was that guy and what was that about?"

..that kind of error-message yells to me that I should try a number with three dots. And scientific notation. And Little Bobby Tables' age.
What was your question again?

If you can't read my code, try converting it here[^]

Example:
I take a picture with webcam and save it whit name "A" at desktop (fixed)
How can I open it without using opendialog and select it?
I want to click a button and winform default open image with name "A" and path.
Thanks for your help

Then you're going to have to write code to create the filepath to that image. All a OpenFileDialog does is let the user select a file or files and return their filepaths, that's it. It doesn't actually do the "open" operation on the file. That's up to your code.

Thanks for your guide, but can you give me the code, I am beginner and I can't write the code by myself! I can read the code and try to understand it. Thank you

Code for WHAT? I have no idea what you're doing or what you need code for. This site is not in the business of writing code for people on demand.

I need to add deserialized data from xml file to the model in Entity Framework cod efirst in order to generate my database in SQL Server CE.
The problem was that I have two tables , the first was done without problems but when I added the second model I got an exception :
{"Exception has been thrown by the type initializer for 'DAL.MyModel.InformationContext."}
I will be so thankful if someone could help me .
Here my source code in the Program.cs:
using (InformationContext db = new InformationContext())
{
db.Balances.Add(new Balance_Model()
{
EuroBookingBalance = Bal.ElementAt(0).EuroBookingBalance,
Id = Bal.ElementAt(0).Id,
ABI = Bal.ElementAt(0).Account.ABI,
BBAN = Bal.ElementAt(0).Account.BBAN,
CIN = Bal.ElementAt(0).Account.CIN,
Currency = Bal.ElementAt(0).Account.Currency,
Description = Bal.ElementAt(0).Account.Description,
Number = Bal.ElementAt(0).Account.Number,
AccountId = Bal.ElementAt(0).Account.Id,
Date = Bal.ElementAt(0).Date.ToString(),
AccountHolder = Bal.ElementAt(0).Account.AccountHolder,
CAB = Bal.ElementAt(0).Account.CAB,
CurrencyBookingBalance = Bal.ElementAt(0).CurrencyBookingBalance
});
db.Transactions.Add(new Transaction_Model()
{
ABI = tra.ElementAt(0).Account.ABI,
AccountDescription = tra.ElementAt(0).Account.Description.ToString(),
Amount = tra.ElementAt(0).Amount,
TransactionDate = tra.ElementAt(0).TransactionDate.ToString(),
AdditionalDescription = tra.ElementAt(0).AdditionalDescription,
AccountHolder = tra.ElementAt(0).Account.AccountHolder,
CAB = tra.ElementAt(0).Account.CAB,
Currency = tra.ElementAt(0).Currency,
Description = tra.ElementAt(0).Description,
Id = tra.ElementAt(0).Id,
Number = tra.ElementAt(0).Account.Number.ToString(),
ValueDate = tra.ElementAt(0).ValueDate.ToString(),
AbiReason = tra.ElementAt(0).AbiReason.ToString()
});
db.SaveChanges();
Here my Initializer class ;
class DbInitializer : DropCreateDatabaseAlways<InformationContext>
{
protected override void Seed(InformationContext context)
{
string pathXml = @"C:\Users\Mohamed amine sifi\Desktop\balancess.xml";
Balances Bal = new Balances();
XmlSerializer serializer = new XmlSerializer(typeof(Balances), null, null, new XmlRootAttribute("Balances"), "urn:Cedac:WebContoc:Balances:v1");
StreamReader reader = new StreamReader(pathXml);
var xmlReader = XmlReader.Create(reader.BaseStream);
object deserialized = (Balances)serializer.Deserialize(xmlReader);
Bal = (Balances)deserialized;
string pathXmlt = @"C:\Users\Mohamed amine sifi\Desktop\transactions.xml";
TransactionsList tra = new TransactionsList();
XmlSerializer serializert = new XmlSerializer(typeof(TransactionsList), null, null, new XmlRootAttribute("Transactions"), "urn:Cedac:WebContoc:Transactions:v1");
StreamReader readert = new StreamReader(pathXmlt);
var xmlReadert = XmlReader.Create(readert.BaseStream);
object deserializedt = (TransactionsList)serializer.Deserialize(xmlReader);
tra = (TransactionsList)deserializedt;
context.Balances.Add(new Balance_Model()
{
EuroBookingBalance = Bal.ElementAt(1).EuroBookingBalance,
Id = Bal.ElementAt(1).Id,
ABI = Bal.ElementAt(1).Account.ABI,

AccountId = Bal.ElementAt(1).Account.Id,
Date = Bal.ElementAt(1).Date.ToString(),
AccountHolder = Bal.ElementAt(1).Account.AccountHolder,
CAB = Bal.ElementAt(1).Account.CAB,
CurrencyBookingBalance = Bal.ElementAt(1).CurrencyBookingBalance
});
context.Transactions.Add(new Transaction_Model()
{
ABI = tra.ElementAt(1).Account.ABI,
AccountDescription = tra.ElementAt(1).Account.Description,
Amount = tra.ElementAt(1).Amount,
TransactionDate = tra.ElementAt(1).TransactionDate.ToString(),
AdditionalDescription = tra.ElementAt(1).AdditionalDescription.ToString(),

base.Seed(context);
}

Hi i want to design account class. with lock keyword in withdraw method.

Unless you are using threading within your application, lock is pretty much irrelevant. It will not prevent other instances of your application from making changes, even if they are on the same PC.
However, the MSDN[^] article on lock covers it prety well if you are threading.

Ok, but that's not a question. What do you want to know?

I am attempting to filter a list, nothing unusual, done it 1000s of times.
List<NBAggDB> lAgg = lNBAgg.Where(x => x.NodeKey.StartsWith(oParentNode.NodeKey)).ToList();
ParentNode is populated and has a NodeKey, lNBAgg is a List<nbaggdb> and is populated and all have valid NodeKeys
Yet I get the following exception an the only null object is x and the following is highlighted by the exception.
x.NodeKey.StartsWith(oParentNode.NodeKey)
{System.NullReferenceException: Object reference not set to an instance of an object.
at Texas.ViewModels.NewBusinessVM.<>c__DisplayClass11.<LoadAggRows>b__10(NBAggDB x)
at System.Linq.Enumerable.WhereListIterator`1.MoveNext()
at System.Collections.Generic.List`1..ctor(IEnumerable`1 collection)
at System.Linq.Enumerable.ToList[TSource](IEnumerable`1 source)
at Texas.ViewModels.NewBusinessVM.LoadAggRows(TreeNodeNB oParentNode)
at Texas.ViewModels.NewBusinessVM.LoadBudgetCells(TreeNodeNB oNode)
at Texas.ViewModels.NewBusinessVM.LoadNodeChildren(TreeNodeNB oParentNode)
at Texas.ViewModels.NewBusinessVM.LoadNodeChildren(TreeNodeNB oParentNode)
at Texas.ViewModels.NewBusinessVM.LoadNodeChildren(TreeNodeNB oParentNode)

at Texas.DataServices.NBBudgetDS.NBBudgetForPeriodCompleted(Object sender, NBBudgetForPeriodCompletedEventArgs e)
at Texas.TexasSvc.TexasSvcClient.OnNBBudgetForPeriodCompleted(Object state)}
How the hell am I supposed to debug that?

I've run into this a couple of times with the database I'm working with.
The code works, right up until one of your NodeKey objects is null, OR, in your case, oParentNode is null. Somewhere in that pile of data you're working with...
|
|
|
|
|
It was actually caused by a type mismatch between the database and the object, the conversion is done in the DAL and returns a null object when there is a mismatch, I forgot to put in the error trap and got bitten AGAIN! The code is all generated at that level and I have not moved the trap into the code generator  .

That sounds like a better problem to have than the one I've got! Trust me, you don't want to know. On top of that, it's a problem of my own creation!
