.NET Development How to Create XmlElement Proxies?
Hi all, I have a collection of XML documents identified by ids. The documents contain elements that refer to other documents by their ids. In other words, the XML documents are like a graph of XML data. Various views are used to display different parts of that graph using XSLT. The views should pull the necessary XML from the corresponding documents. For that means, I would like to instantiated proxies for thoses XmlElements which refer to XML documents. The referred XML documents should be loaded only when the view actualy is interested in their content, i.e. pulls out their content. What methods and properties of XmlElement must be overridden in order to achive such a behaviour I guess that ChildNodes must be overridden. What else Has an ...Show All
SQL Server Long parameter list for stored procs
Hi All, I've got a problem with increasingly long parameter lists for SProcs... Especially when one calls another SProc, and so on. Is there any way around this Like can you dynamically construct a string and pass that I'm just looking to see if more experienced players have found ways around this, or have just dealt with it by using well formed code. Thanks Chris To me it is a question of numbers. If you have a long list of parameters, but they are fixed in number, then I would certainly stick to just writing well formed queries, not putting stuff into arrays or any of that other stuff. That method should be considered mostly for unknown numbers of parameters, paticularly when you need to pass unknown numbers of values to ...Show All

Visual C# best way to read pipe delimited text file?
I am trying to read in a pipe delimited file and do certain processing for each field. I was just wondering what the best way to strip out each field is - is there anything built in .Net that will easily allow me to do this Or do I just loop through and remove each field myself Also, would it be best to strip each field out into a dataset first, and then do the processing Or, do the processing while I am separating each field Or does it not matter Thanks! Saeed it really depends. You can split the entire lines read into a string[] array if you like: string[] theLines; StreamReader theReader = new StreamReader("file.txt"); theLines = theReader.ReadToEnd().Split(new char[] { '|' }, Strin ...Show All

Visual C# Setting Font Size on Thumbnail Image
Hi, Can anyone tell me why when I use the code below, the font size comes out a different size on each thumbnail image System.Drawing.Image theThumbnail= bmp.GetThumbnailImage(width, height, myCallBack, IntPtr.Zero); Graphics g= Graphics.FromImage(theThumbnail); g.DrawString("SOLD",new Font("Verdana",6, FontStyle.Bold), new SolidBrush(Color.FromArgb(100,255,255,255)),0,0); I got it set to the perfect size for my test image, then tried another image and it was too small.

Hi, I am developing in c# and am new to the .net framework. I am using the DataGridView to display information from a database (frequency per run number within a certain date range).
