Bitmap.GetPixel() is that what you need but remember that this is slow. You can use unsafe code instead.

Hello everyone,
I am new to programming world. I have been learning c# for about past four weeks. I am quite acquainted with the fundamentals of c#. Now I have to work on a project which converts given flat files to XML using the XML serialization method. I am given with the various flat files and corresponding mapping files. These mapping files itself are in XML (.ltm extension). Now I have to generate XML files from the flat files that adhere to the schema of these mapping files. And for this I have to use XML serialization and deserialization process written in c# code.
Why XML serialization/deserialization?
Because I have generated xsd of the given xml mapping files and imported that file into my solution as xsd.cs so that I can have various nodes of this mapping file available to me as a classes. I mean, I can directly write classes belonging to various elements in this mapping file. As a result I do not have to parse these mapping files using Read and Write properties.
I am asked to create the instances of these classes and use the serialize/deserialize methods to get the work done. Now my problem is that I do not know how to exactly create the classes in this situation and go about serialization and deserialization. So can any one help me out in this situation by providing some sample codes/snippets related to my work. It would be great if someone can actually provide me with steps/algorithm to go about this project. Let me specify one more thing, all the mapping files corresponding to different flat files have the same structure, only the text values corresponding to various Elements are different.
Thank you very much.

I guess you want to write code in those methods that turn the classes in to XML or read them from XML then.

I was fixing bugs in C# barely 2 weeks after being hired (never having touched the language before), and thanks to a bureaucratic snafu didn't have a PC for the first 3ish days.
Today's lesson is brought to you by the word "niggardly". Remember kids, don't attribute to racism what can be explained by Scandinavian language roots.

Can you use CommandBehavior.SequentialAccess with data in a VARBINARY column?
I have a downloads pulling from that column but not doing it that way.... here is my code:
int bytesSize = 0;
byte[] downBuffer = new byte[1024];
byte[] buffer = (byte[])cmd.ExecuteScalar();
conn.Close();
MemoryStream ms = new MemoryStream(buffer);
FileStream fs = new FileStream(Path, FileMode.Create, FileAccess.ReadWrite);
while ((bytesSize = ms.Read(downBuffer, 0, downBuffer.Length)) > 0)
{
fs.Write(downBuffer, 0, bytesSize);
WriteTextBox((fs.Length / 1024) + "KB of " + (ms.Length / 1024) + "KB.");
bw.ReportProgress(Convert.ToInt32((fs.Length * 100) / ms.Length));
}
fs.Close();
ms.Close();
The problem is it gets all the data here:
byte[] buffer = (byte[])cmd.ExecuteScalar();
So if I'm correct it is getting ALL of the data there. Which if it is a large file.. not even that large, it pauses there until it gets it.. Now on remote connections it times out because it doesn't have that long. But also the way I have it reports progress when writing to the file, but I want to report progress on downloading the file.
I have seen code used with this for BLOB data, but the column is not the type TEXT.

You mean you want to show progress when ExecuteScalar is working? AFAIK, that is not possible. There is no way to know how the long the SQL is going to take. There is asynchronous methods like, BeginExecuteReader available. This method will not block the current thread. So you can display some message to user saying the progress.

I need to create simple query designer. because we need to give sql query designing part to our customers. The main headache to me is visualize the joining. I use custom controller (checkedListbox and button) to visualize the table. Please help me to do this.

I wrote a query designer way back. You can find the implementation at www.analysis6.com[^] it is not open source. Start looking for sources matching what you need and check out other implementations. Good Luck

I'm building a custom control inherited from a picturebox control, and I would like it to automatically resize to the dimensions of the container control to which it is added(could be any valid container control)
Referencing the Parent of the custom control in its structure definition
Public MycustomePicBox()
{
this.Size=new System.Drawing.Size(this.Parent.Clientrectangle....
}
isn't possible because at the time the code executes, the custom control hasn't been added to the container control yet.
Is there an event that fires for a Control when it has been added to a container?

I hope I haven’t got the wrong end of the stick of what you’re trying to achieve.
I’ve just had a quick look, and found that there’s an event available for when controls are added to a user control. Try using the ControlAdded Event.
To initialize it do the following…
<code>
public userControl1()
{
InitializeComponent();
/*
Please note, the code below should really be inside InitializeComponent();
But for speed, i've added it in here.
Add the line below…
Note: Press Tab key after typing in += as this will auto complete the rest of the event.
*/
this.ControlAdded+=new ControlEventHandler(userControl1_ControlAdded);
}
private void userControl1_ControlAdded(object sender, ControlEventArgs e)
{
// execute your methods for resizing to parent control.
}
</code>
I hope this has helped?
P.S. I am using the latest version of C#.Net framework 3.5 so I’m guessing that these events are also available for frameworks 1.1 and 2.
Rule 1 - Don’t break what’s not broken!
Rule 2 - Don’t reinvent the wheel… just give it a lick of paint!
Rule 3 - Keep plenty of programmer foods to hand… Pizza, beer & crisps... including the books on "How to Crash Your System in Twenty Seconds!"

I think that event fires for the container control.

Hi,
If your question was not specifically about environment variables but instead about the directory containing the common language runtime then take a look at the System.Runtime.InteropServices.RuntimeEnvironment class.
The GetRunTimeDirectory method may be what you want.

Hi,
I'm new with C# and I have a little problem.
I'm trying to make button and when the user clicks the button,
textbox shows message "This works!"
However, nothing happens when the button is pressed down.
Could you please help me?

Hi,
you have to add the following line into your InitializeComponent Method
this.NaytaTeksti.Click += new System.EventHandler(this.NaytaTeksti_Click);
otherwise your Event Handler is never called.
Regards,
Jens

Hi,
As JF2015 said, there is a line missing.
However, when using Visual Studio, you are not supposed to edit tje InitializeComponent() method, it is generated and managed by Visual Designer.
So either use the Visual Designer to add a click event to your button, or add the new line to your Form1 constructor, right after the call to InitializeComponent().

kiddo…… NaytaTeksti_Click(object sender, EventArgs e)
this event dosn't belong to any Control
here:
this.NaytaTeksti.Location = new System.Drawing.Point(80, 88);
this.NaytaTeksti.Name = "NaytaTeksti";
this.NaytaTeksti.Size = new System.Drawing.Size(128, 23);
this.NaytaTeksti.TabIndex = 0;
this.NaytaTeksti.Text = "Nayta";
this.NaytaTeksti.Click+=new System.EventHandler(this.NaytaTeksti_Click);//please add this

Hi! Is there a way to acquire the letters from the grid of this game:(it is in Bulgarian)
The game is:http://bezumie.com/dumino/[^]
In the text field you write a player name. Then you click the button next to it - "ВХОД". When the page loads there is a grid, which eventually fills with Cyrillic characters. How can I get the characters with a C# application???
Via Firefox I saw the page source. There is a board array which contains the characters. But I don't know how to access the information with my program.
Still learning...

well, this is bad idea to do this on sites...but a little hint, that input element id is 'fld'.
