Can´t run before you walk.
XML can become pretty complex very soon so time or no time, my advice would be to complete a tutorial (a book, no website) reading, including excercises before diving into this.
C# and XML, I would recommend LINQ (to XML), but before diving into LINQ you need a thorough knowledge of .NET.

Different approach from Pete's answer is to use XMLSerializer deserialize[^]
Google has many examples that you could work from.

If you are totally new to programming as well then you might want to give up.
If you however experience in the SQL of your database then it is likely you can solve it using only that and much faster than learning enough C# to meet your "urgent" need.

If you use Linq To XML, you can do 90% of the processing with a single class: XElement. Linq To XML is elegant, and gives you (for example) IEnumerable lists you can process with foreach. It's my first choice for parsing XML.

The Picturebox I believe.
PictureBox pictureBox1 = new PictureBo();
pictureBox1.Image = System.Drawing.Image.FromFile(@"");
With great code, comes great complexity, so keep it simple stupid...

Well, to handle the image management and display, I'd use the techniques I wrote about in this[^] article.

Hi!
I need to be connect to DB2 Database in my Project,it seem'd to be a easy task but i got some problems. I tryed to install IBM Add On for Visual Studio but i cant install it (like it could be only installed on normal visual studio but not on free express) It is a AS400 DB we connect using port 10 to address 192.168.52.10 on local server. I'm a newbie so please write in simple language  Thanks Chris

Well, you haven't really explained what the problem is, apart from implying that you need an IBM addin. However, you may find http://www.connectionstrings.com/[^] a good place to look for some suggestions.

Hi Thanks for reply.
I try'd on the start the default OLEDB driver but cant menage the conn. string.
Got Error Message
base {System.Data.Common.DbException} = {"[DBNETLIB][ConnectionOpen (ParseConnectParams()).]Ungültige Verbindung."} (not guilty connection) ,ErrorCode = -2147467259
The Address and port are ok , vpn connection is fine.
Here are my connection string settings:
1)
string conn_str = @"Provider=SQLOLEDB;Network Transport Library=TCPIP;
Network Address=192.168.52.10:10;Initial Catalog=UDVM400DAT;
User ID=xxx;
Password=xxx;
2) second string
string connw = "Provider=SQLOLEDB;Server=192.168.52.10:10;Database=UDVM400DAT;UID=xxx;PWD=xxx;
Can You figure out whats wrong with the conn string? I had problems on running Toad for DB2, the Razor SQL is working but it use some java driver for AS400. Regards Chris

Visual Studio Express does not support Add Ons.
Still, one would not need a visual studio addon to simply connect to a database; your application will probably have to connect to a database sooner or later, without the help of visual studio or it's addons.
What you'd need is a "Data Provider" for IBM DB2. If none is present, use the OleDbProvider and it's related classes.

First things first. Google for "SQL Injection Attack" to find out why building a SQL query string like you have is such a bad idea. I'll give you two hints: Security and Maintainability.
Then Google for "C# Access Parameterized Query" for what to do about it.

Alright thank you Dave I will.
|
|

"Username" is a reserved keyword[^], and a bad choice for a column-name. You'd have to escape it, probably by putting it in [username]. A better solution would be to rename the column.
You'd also want to be using "parameterizes queries" to prevent people like me from deleting everything in there. And instead of manually disposing, I'd recommend using a using clause.

hi
i have a problem in receive data from serial port in c# , i do`nt now why create this problem in my application .the error is :
ErrorDeviceApplication4.exe
NotSupportedExceptionControl.Invoke must be used to interact with controls created on a separate thread.at Microsoft.AGL.Common.MISC.HandleAr(PAL_ERROR ar)at System.Windows.Forms.Control.get_Text()System.Wind ows.Forms.Control.set_Text(String value)at DeviceApplication4.Form1.Port_DataReceived_1(Objec t sender,SerialDataReceivedEventArgs e)at System.IO.Ports.SerialPort.CatchReceivedEvents(Obj ect src, SerialDataReceivedEventArgs e)at System.IO.Ports.SerialStream.EventLoopRunner.CallR eceiveEvents(Objectstate)at System.Threading.ThreadPool.WorkItem.doWork(Object o) at System.Threading.Timer.ring()

As the error suggests, there is a problem since you are possibly trying to access the UI thread on the thread that is listening to the serial port.
Use BeginInvoke to access controls on the main thread.

i dont use thread in my application .
in your reply for post means i use thread in my application?
|
|
|
|

Yes, you are. Read the documentation on the DataReceived Event[^. From the MSDN documentation:
The DataReceived event is raised on a secondary thread when data is received from the SerialPort object. Because this event is raised on a secondary thread, and not the main thread, attempting to modify some elements in the main thread, such as UI elements, could raise a threading exception. If it is necessary to modify elements in the main Form or Control, post change requests back using Invoke, which will do the work on the proper thread.

I hosted my Web application project in IIS. When I used it in Integrated mode the form is not submitting, but it works fine in classic mode. I don't know why it behaving like this?. Is there any way to fix it?
In the screenshot images of the following link ( http://stackoverflow.com/questions/18831086/iis-hosted-site-not-working-properly-in-integrated-mode-but-working-fine-in-clas), i have represented the problems we faced. It's a big headache and we are trying for hours to solve this problem. Yet we didn't find any solution.
In the integrated mode as in the above, the action attribute of form element is "/" so that the form is not submitting to the right path.
Actually it has to be submitted to the causeprofile.aspx page but it didn't.
In the integrated mode it renders the form element with action attribute as "/". But in Classic mode it renders the form element with action attribute as "/causeprofile.aspx".
What is the difference between these?
Please kindly help me on this issue.
