Duplicate record in XML Tufail Ahmad13-Sep-09 21:36 Tufail Ahmad 13-Sep-09 21:36  I use C# and storing data in XML file. the problem is that how can i avoid xml file to save duplicate record. in table it can be detected using Primary Key but how can i do it in xml. e.g. in xml file i saved ProductID=1, next time when i try to save ProductID=1, it should automatically alert me that Key already exists. help please Re: Duplicate record in XML SeMartens13-Sep-09 22:06 SeMartens 13-Sep-09 22:06  Hi, XML is just a "dumb" datastructure. Using a database you have a layer between your app and the datastore called "DBMS" (Database management system). This system checks if you try to insert a duplicate key. Using your XML structure you have to write this "DBMS" by yourself. So I suggest write a layer which will check for duplicate keys. Regards Sebastian It's not a bug, it's a feature!

Re: Duplicate record in XML Tufail Ahmad13-Sep-09 22:40 Tufail Ahmad 13-Sep-09 22:40  the solution could be xsd file, but i dont know to use it Re: Duplicate record in XML SeMartens13-Sep-09 22:49 SeMartens 13-Sep-09 22:49  Well, could be a possibilty. Look here to see how it works: http://www.xml.com/pub/a/2000/12/13/schemas/part2.html?page=2[^] The problem is, that you can add the same identifier to the file without any error message. The XSD will only help you to say, if the XML file is valid according to the defined schema. So you could add a possible duplicate key to the file and validate the xml afterwards with the xsd. If the validation fails you know that the insertion of the key was not correct. It's not a bug, it's a feature! Check out my CodeProject article Permission-by-aspect. Me in Softwareland.

This is not fool proof method as XML is just a text file which any one can open in any text editor and add duplicate data.

If you have relational data (and from your post it looks like you have) to store you should use a relational database, if cost is a problem there are perfectly adaquate free ones available, such as MySql: http://en.wikipedia.org/wiki/MySQL[^] or Microsoft's own SQL Server Express: http://www.microsoft.com/Sqlserver/2005/en/us/express.aspx[^] As it stands, you are making a rod for your own back by using XML, doing all the work that the database can do for you. If you do decide to use a database, normalise it properly or you won't get the full benefit: http://www.dbdebunk.com/index.html[^] Bar chart not displayed mozilla but displayed in firefox while implemented dynamically in c# mathewaugustine13-Sep-09 21:19 mathewaugustine 13-Sep-09 21:19  Bar chart not displayed mozilla but displayed in firefox while implemented dynamically in c# Re: Bar chart not displayed mozilla but displayed in firefox while implemented dynamically in c# dan!sh 13-Sep-09 22:05 dan!sh 13-Sep-09 22:05  mathewaugustine wrote: Bar chart not displayed mozilla but displayed in firefox It's not necessary to be so stupid, either, but people manage it. - Christian Graus, 2009 AD Re: Bar chart not displayed mozilla but displayed in firefox while implemented dynamically in c# Keith Barrow14-Sep-09 0:09 Keith Barrow 14-Sep-09 0:09  LIQUID NITROGEN Re: Bar chart not displayed mozilla but displayed in firefox while implemented dynamically in c# Christian Graus14-Sep-09 0:50 Christian Graus 14-Sep-09 0:50  The error is on the second line of your code.

Christian Graus13-Sep-09 19:29 Christian Graus 13-Sep-09 19:29  The only mail setting I know that you're not setting is 'UseDefaultCredentials'.

Shafik Re: The remote certificate is invalid according to the validation procedure. Christian Graus13-Sep-09 19:45 Christian Graus 13-Sep-09 19:45  np. I suspect you want to use the useDefaultCredentials to false, for it to send as ssl. Christian Graus Driven to the arms of OSX by Vista.

Image croping Game-point13-Sep-09 18:25 Game-point 13-Sep-09 18:25  Hi All I have to crop the images from picture box . before that i loaded the images in the picture box its showing only the half of the images ..how to using Scroll bar in the picture box...and how to crop the portion ... regards ~~~~~~~~~~~~~Raju~~~~~~~~~~~~~ Re: Image croping Christian Graus13-Sep-09 18:32 Christian Graus 13-Sep-09 18:32  You need to start again. First, you don't want to use a picture box. You want to draw the image yourself, in your paint handler. Then you want to use mouse events to define a crop area. Then you want to create a new bitmap that contains the cropped area. I suspect you will need to do a bit of research and learning before you can do all that.

The point of that control is to allow limited viewing of images for people too inexperienced to write some basic code. One you want to do anything more than show the image, the control will get in the way, it will not help at all. Christian Graus Driven to the arms of OSX by Vista.

How can I do this?? Help please! Thanks
