Because the TS gave an example where he'd convert a small structure to a string and back. If he had asked how to store a class or a collection, I'd answered serialization.

I beleive you have to read the entire file in order for it to validate try this Settings = new XmlReaderSettings(); Settings.ValidationType = ValidationType.Schema; Settings.Schemas.Add("http://tempuri.org/Unit.xsd", Directory.GetCurrentDirectory() + strXmlSchema); Settings.ValidationEventHandler += new ValidationEventHandler(OnSchemaValidationError); using (XmlReader Reader = XmlReader.Create(Directory.GetCurrentDirectory() + strXmlFile, Settings)) { if (Reader != null) { while(Reader.Read()){} } }

Your application should have a data model somewhere. Ignore the UI for the moment and think about the business logic and the data layer. Typically your main application class (this is often MainForm, though if one is being strict it shouldn't be) will have a reference to a data model – for a simple application this might just be the data set. Any UI views that refer to the data model should then be given a reference to it, possibly via a view-model (or presenter or similar) class if the binding process is more complex than being a direct editor of some part of the data model. Anything more than simple updates should be done with logic in the model layer, which is why you may need to write a class instead of just using a data set. So the short answer is, put it in your main form class or your application class, if you have one, and pass a reference to it to the MDI children when they are created. But I would like you to understand why that is a good idea and how to extend it to more complex view/model situations.

As long as you access them via the BLL.

I'd say in a Windows Forms project that is perfectly acceptable and gives you the control you need to validate the data entered. In WPF however you really want to take advantage of the binding model within WPF and MVVM. I have heard that people are successfully implementing MVVM in Windows Forms which would be a nice way to go. "You get that on the big jobs."

AFAIK you must apply your (custom) sort on the underlying data structure, not the DGV itself. So set the DGV to programmatic sorting, handle the cell click event (checking for row<0 and getting the column index), and sort your DataTable or whatever is underneath the DGV. :) Luc Pattyn [My Articles] Nil Volentibus Arduum The quality and detail of your question reflects on the effectiveness of the help you are likely to get.

Did you move it using Windows Explorer, or did you move the file from within the VS IDE? paper67 wrote: When I place it in the root folder everything works fine. I'm guessing that VS cannot update the path to the files when you copy it using the Explorer. You could try to drag&drop it in the 'Solution Explorer' in the IDE, that should update all references during the move. Bastard Programmer from Hell :suss:

If you could present some very brief but complete code that illistates your problem I could easily correct it, but it must be brief and complete.

Oh thank god =) Not a problem - glad it finally worked

I'm having the same problem and haven't got any clue yet.

Do you have any Javascript code too associated with the page? 'className' is a javascript attribute and the error sounds like client side. Check if you have assigned/missed any css.

It is properly linked. I have other styles defined in the CSS file that work properly.

This is because you are not using an UpdatePanel. add an UpdatePanel on the page and put everything inside except ScirptManager . and it will work. and also use the scriptmanager instead of toolkitscriptmanager. if you want to do this without AJAX for testing then add Response.Redirect("~\ThisPage.aspx"); after you set the combobox enable true or false, and you dont have to click twice to enable or disable it.

You mean paper67 wrote: if (!string.IsNullOrEmpty(Context.Request.QueryString["color"])) Evaluates to false ? Did you put the QueryString correctly. Use HttpUtility.UrlEncode before sending the color code. And after fetching use HttpUtility.UrlDecode to get the color code back properly.

AFAIK, it isnt :( . You might collapse / expand the portion of html though in the source of Design view. But why do you require to see the design view? I always work with the source as design view places lots of unnecessary css which makes the pages unnecessarily heavier. I would recommend you to write your own html, rather than depending on the design view. :rose: Abhishek Sur **Don't forget to click "Good Answer" if you like this Solution.

Mike Dimmick wrote: Imagers, which simply take an image in the same way as a digital camera, can generally handle both 1D and 2D barcodes. FYI, there's a third category of reader (probably not used so much anymore, now that imagers have become cheaper): raster-scanning lasers can scan 1D barcodes and PDF-417 but not other 2D symbologies. PDF-417 is designed so that it can be read by combining many independent one-dimensional reads. If a particular read crosses from one 'row' to the next, the character on which the crossing occurred will not be read, but the system will detect the crossing and can thus properly assign the following characters to the appropriate row. I mention this for a few reasons: -1- I think PDF-417 is a really cool technology which, although it's obsolete, still deserves to be appreciated and marveled at. -2- While I don't know the market situation, I would not be surprised if used raster-scanning lasers are or will be available cheaper than other imaging technologies. If information capacity is more important than small symbol size, using PDF-417 may allow one to equip one's shop with compatible readers more cheaply than other symbologies. -3- With a firmware upgrade, a line scanner that has enough memory should be able to handle PDF-417 barcodes if the user waves the scanner slowly over the barcode a few times, though I'm not aware of any that do. This might make an interesting hobby project, though. -4- PDF-417 barcodes are physically larger than other 2D barcodes with similar information content; it may be nice to understand why.
