Thanks.

ObservableCollection in .NET 4.0 already implements the Serializable attribute. See here for refrence: http://msdn.microsoft.com/en-us/library/ms668604.aspx. I do also try to add the Serializable attribute in all of my entity class but still the error occurs. I am very thankful for your reply, but still It doesn't solve it. Please help.

Is there really no other way? :(

Actually I'm implementing the INotifyPropertyChanged in my base class but I still need to add a line of code in the set accessor of the properties of the concrete class that will call the method that raises the PropertyChange event handler. Still this same question will arise.

That would only work if the class that inherit the web service class is in the same project as the web service or it referenced the project of that web service. What I have was the class that needs to inherit the web service class is in a project that web referenced that web service.

Yes, but I need it to be generic because it defines an entity with a data type of T, or a defined data type, and I think changing it to a concrete class is hypothetically impossible(contradicting my comment here a while ago).

Thanks for the answer but my question is how to inherit an abstract class from a web service class, not from a class to the web service class, to the class within the project that referenced that web service. Your reply is highly appreciated though.

The abstract generic data access class has methods that connects to the database within the same server as the web service. It can also be done by making the data access class concrete and instantiate it in the local concrete class and create methods for each method of that data access class, I just want to inherit it so that it would be easier, but if there has no other option, how can I access a concrete class written inside a web service class?

Thanks for the reply. I have a generic data access class that can only be inherited. That's why I need an abstract class, but if it is a concrete class, how can I access it?

No one is answering... :(

thanks..

That would'nt work for me, the parameter array was only always a single dimension array, If I'm going to pass a dataset, I atleast need a two dimension array for rows and columns. Thanks for the reply. But I still need help.....

I already looked into that. But the xml function of MySql can't return a Table Set. It only return a scalar value. What I need is like what I do in my MSSQL stored procedure. But thanks anyways..

It works! Thank you very much. I am waiting for a day for an answer.

Superb.. Thanks..

I haven't thought about it. I'll try it. Thanks.

Thanks, but that will make all the value of that field the same. My 'manipulation' means that the value will be processed (by my code) and the report will reflect it. Is it possible?

Yeah! It works like magic. Thank you very much!

I also thought that but, there's no other way to do it(except to insert all excel values in a DataTable which cost a lot of work). And why 'might'? not always?

The inputs(_insured.StrDepFname ...) is from the excel file too. Yes, it is subject to sql injections, but even if the values is correct the error still occur. I haven't really checked what line the error occur because it loops too many time before an exception is thrown. Even if the inputs are all the same, still the error occur not in the first execution of the loop but on the n? times the statements inside the loop had already been executed. Is it because of reconnecting in OleDb too many times?

I did not mean to offend you. :P I'm just like this. Sorry.

I don't really think there has an error on my code(I had checked it a million times).

yeah! it works.. thank you very much. I have not think about the Convert.. ugh.. I've been debugging this for a whole day.. thanks again..

There was an error:
Could not find an implementation of the query pattern for source type 'System.Data.DataView'. 'Select' not found. Consider explicitly specifying the type of the range variable 'row1'.

And I really cannot specify the columns of dtTable since I put it inside the foreach statement that makes the columns of dtTable different at each loop but the first column is always the IndexID.

I already try the contains but it throws an error:
{"Specified cast is not valid."}

dtTable is from MySQL, IndexID is in int(11) data type.
dtUploadedIDs is from MSSQL, IndexID is in string data type but you can convert it to int since it only contain numbers.

What could be the problem?

Sorry. Its my first time to post a question.

I think it is not possible since the local database is in MySQL while the main database is in mssql but thanks for the reply.
