• Bear23 What happens underneath the BulkCopy Object of ADO.NET 2.0

  Hi , Does someknow how does new Bulkcopy work in ADO.NET 2.0 What happens underneath because of which the performance gets better with BulkCopy Regards, Anjana I'm not sure which wizard you're mentioning, there is no wizard for ADO.NET SqlBulkCopy (note there ARE wizards for bulk-loading data into the server, they come with SQL Server; but those won't generate stand-alone C#/VB programs). If you want to validate the data sent to the server through SqlBulkCopy, you have two options: - Validate before sending it. Either by preprosessing the data before creating the input to BCP, or by intercepting the input. One way of doing this in a streaming fashion is to create your own DataReader class that consumes data fr ...Show All

• Wlimit XslCompiledTransform loading external xml from database using document()

  I have some xml and xsl documents all stored in a database, so there are no physical files. I use the XslCompiledTransform and a custom XmlUrlResolver class to load xsl documents from the database. My custom XmlUrlResolver class only resolves the import and include directives. How can I write a custom resolver for the document() directive answering my own question: adding writer.WriteDocType(..) solved the issue. From the VS2005 documentation : C# public void Transform ( XmlReader input , XsltArgumentList arguments , XmlWriter results , XmlResolver documentResolver ) C++ public : void Transform ( XmlReader ^ input , XsltArgumentList ...Show All

• David_Reynolds Solution for shared list

  Hello, I need to create server/client with such funtionality: Server has list, which is shared with alll clients. This means, that all connected clients see the same list. If any client removes item from the list, server and all other clients must imiadetly refresh their list. If not talking more about specific software functionality, I can list such things about comunication, what I need: Communication between applications would be through WAN (internet), so optimal solution for network bandwidth and server resources is critical. In the beginning there would be ~40 clients and this number can increase to 100. Communication channel must be secure, that no one could read or change traveling data. Author ...Show All

• Lars Brange More error info:

  I'm calling a remote server (client activated, hosted in WinForms app). A simple call without parameters (or with a simple string param) works fine. When I pass certain parameters, it crashes. Build is the remote class. This call to CreateBuildTree() works: Build prp = new Build (); prp.CreateBuildTree(); This one doesn't: Build prp = new Build (); string BuildDir = prp.GetBuildDir(); TreeNode root = new TreeNode (); root.Text = BuildDir; prp.CreateBuildTree(root, BuildDir); even when CreateBuildTree doesn't contain any code!!! public void CreateBuildTree() { } The error I get on the client side is "Server encountered an internal error.

• Constantijn Enders Detecting a router's external IP

  Hello everybody, I'm just getting started in the realm of networking w/ the .NET framework. I'm coding my app in C#, it's just a simple command line server that will listen for commands from an external client. Right now, I'm just trying to get the server, when started, to print out the local machine's IP. However, I want it to print out the address as seen by computers not on my network. So, instead of 192.168.1.XXX, I want it to give me what a website like http://whatismyipaddress.com/ would return. Thanks in advance! If you have a web server yourself, the easiest way for one of your programs to get its WAN IP address is to do what Aymaneez suggests, but to load the address from your own web server. T ...Show All

• jm83 Datatable Vs. Excel workseet

  Hi, My application is using a Excel file as the data storage. I am now connecting to the Excel sheet by using Jet Engine OleDb objects and then perform searching. The search process takes 25-30 seconds and it seems a bit too long. Then I found out another method is to load Excel data into a dataset. does anyone know that which method is faster to search and can SQL statement be used in the latter method Thanks! Carol I believe it depends on type of query you are using, but take into account that Excel is not a real database and does not have indexes for the columns. It means that each condition in your query would require full scan of the columns. In a case if you load data into DataSet and use DataVew or Select method, th ...Show All
