• Master Programmer Getting wrong path from Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location

  Hi I am getting wrong location for my file. My file is at different loaction but "Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location" always returning "C:\Windows\System32" path. But it runs ok on other machines. What could be the reason for getting system32 path instead of actual file path. The file is running as windows service. Thanks SAnjivani Bit of a long shot, but services are hosted by c:\windows\system32\svchost.exe... Hi, As you said, it runs ok on other machines, then are you sure that on other machines it is being used same way in Windows Service Because AFAIK, windows service will return this path only, so use AppDomain.Curr ...Show All

• Claudia Alvarado displaying hexadecimal values with leading zeroes?

• nilaavu SqlDataAdapter

  Microsoft documentation for DbDataAdapter.Update Method (DataRow[], DataTableMapping) says: When using Update , the order of execution is as follows: The values in the DataRow are moved to the parameter values. The OnRowUpdating event is raised. The command executes. If the command is set to FirstReturnedRecord , then the first returned result is placed in the DataRow . If there are output parameters, they are placed in the DataRow . The OnRowUpdated event is raised. AcceptChanges is called.

• Josh_G Generate a Class from an XML file

  I have a challenging idea that hopefully someone has some ideas on how to solve... Does anybody have any ideas on how to go about creating a .NET class whose sole purpose will be to read in an XML file and, based on the data contained within the XML file, from it will be able to dynamically create a class I'm not talking about an object of the class, because obviously there's many options to do that. I'm talking about creating the entire class and everything in the class; the name of the class, modifiers, members, methods, properties, etc. I'm not concerned about logic/decision making inside the class, nor am I concerned about events, delegates, threads, and other advanced topics, just the basics that I mentioned.

• msedi Use of Transactions for long slow process and blocking

  Hello, I have a question about the appropriate use of transactions when performing a long task. I have a C# application which runs on a semi-frequent basis. The application downloads data from a number of different data sources, post-processes the data on the fly, then progressively writes the post-processed data out to a local SQL Server (2000) database. The download of data takes about 3 hours, and quite commonly dies part way through (due to unreliable data sources). It seems like a good idea that I wrap the whole download process in a single transaction (using the SqlTransaction object), so that I can roll back if something goes wrong part way through. What I hadn't anticipated, however, is that by wrapping the process in a ...Show All

• BobP - BIM Merging datasets causes an exception within .NET

  We have an application that uses DataSets in conjunction with Windows Forms-based wizards. Each wizard has its own DataSet. When you finish one wizard it merges its data with that of the others, so at the end of the process, there is one DataSet with all the rows in it. The DataSets can contain any number of tables. The DataSet.Clone() method is used to make an empty DataSet, so each instance of DataSet has the same schema. However, from time to time as the application is being used, an exception occurs from deep within .NET at the point where the DataSets are merged. Below are the details of the exception that occurs (I have censored the company namespaces and types for privacy reasons): NullReferenceException - Object reference not ...Show All

• Vladox Managed DirectX 64bit

These are datasets that are bigger than 3Gb and fail without excessive fragmentation of the LOH. I've been investigating running under windows XP 64bit and Vista 64bit.
