• .NET Development DataReader rows into a collection object

  Hi, I have a datreader object with 100 rows,  i created a collection object[ arraylist / hashtable] and stored all the rows to the collection object. I dont want to keep the connection opened that's the reason  i stored the data to the collection object and killed the datareader object. But the problem is I wanted to retrieve the value using column names not by index. For this I looped thru the column names from datareader, how do I merge these two objects Any help is highly appreciated. The datareader gets the data....the datatables persist the data in structured memory...you can also utilize  custom cl ...Show All

• Windows Forms Using XSD schema for field validation when databinding to XML

  I'd like to create an application, part of which involves the customer creating XML documents compliant with a government standard schema. Much of the data will be filled in automatically, but parts will be manually entered by the customer. For the customer data, I want to create a few simple forms for data input. I thought I could use data binding for this. I would like each input field on the form to be validated against the schema definition of that element in the xml file, rather than just validating the finished file all in one go. I know that InfoPath can do this sort of thing, but there does not appear to be a framework in Windows for ...Show All

• Visual C++ OK, What is with the statements enclosed inside [] operator regarding threading?

  I keep looking around to try and figure this out. I keep seeing code with something like [STAThread] on a line by itself. Now, I have figured out that it sets the type of apartmenting you can do. And you seem to use it like the using namespace statements to define if you are going to hae a sta or a mta, but where in the world does the syntax for this statement come from   Is this strictly a COM feature in which it overloaded the [] operator Just wanted to make sure I didn't miss some new language element that I may need. Also, I seem to have gathered that you only need to mark things as STA or MTA usi ...Show All

• .NET Development How can I know the reference count of an object?

  To diagnose memory leak problem, it's convenient to know the "reference count" of an object. Is there any API that could let me I know that e.g.: object obj = ... ... int count = GetReferenceCount(obj); if (count > 0) {       Debug.WriteLine(...); } When the window stays blank, can you scroll the window or click the menu I can scroll it and click the menu after the progress bar (showing the log file is being loaded) disappear, so I think its work has finished. In general, the CLR Profiler will show the result in several seconds on my machine. ...Show All

• .NET Development ConflictOption.CompareRowVersion and Oracle

  Hi, We are using Oracle 10g with VS 2005 (C#), and we want to use optimistic concurrency control. We also want to use DataSets as Business Entities and want the CommandBuilder to generate the Update, Insert and Delete SQL statements automatically based of course on the Select statement. I’ve managed to get it all working, but I want to use a Timestamp column in the tables with the ConflictOption set to CompareRowVersion as the optimistic concurrency mechanism. But when the command builder generates for example the Update statement, it only inserts the primary key columns in the where clause, and not the timestamp column as well. ...Show All
