Real answers would be appreciated.

Please note -- this is not for any malicious purpose. This is for a legit project. Look at Google's use of this idea, for example.

Please explain how and where google has used this idea. I don't remember allowing any components to be installed on my system from the google website.

Things are slightly different but essentially the same in theory.

When you install google desktop and make a search on google.com, the following happens:

You contact google.com and ask for search results. Google sends you an http response. Before returning to your browser, google desktop running on your system MODIFIES the response to add possible local queries and a link on the top that says "Desktop" (next to images groups etc).

Oh Google Desktop. That is certainly different than Google, the website. Guess it pays to clarify your post.

Sorry, don't use it.

I've done this once before by writing an NDIS Driver. That was many years ago and it certainly isn't possible in C#

The basic idea of an NDIS Driver is that it sits and monitors raw packets as they go to and from your network card and allows you an opportunity to drop, modify or permit the packet through. It operates at a very low level and you MUST understand how individual packets are stitched together at the network level (lower level than TCP or IP) because that is all you will see. You will not see a nice stream of data for one connection, you will see everything regardless of how fragmented it is.

Write an NDIS driver to intercept the data at the packet level. You cannot do that in C# tho'

GDI+ Text Rendering

Hello , i have some problems when i am in fullscreen. First text was good in quality but it had problems in characters' edges , so i looked for GDI+ info and found this :

g.TextRenderingHint= System.Drawing.Text.TextRenderingHint.AntiAlias ;

Antialising made it better in edges , but it looked worse this time , it looked fogged ( i am not sure that it is the correct word)

How can i fix it ?
The code is below :

public StringFormat GetStringFormat()
{
int numChars = m_String.Length;
CharacterRange[] characterRanges = new CharacterRange[numChars];
Region[] stringRegions = new Region[numChars];
for (int i = 0; i < numChars; i++)
characterRanges[i] = new CharacterRange(i, 1);
StringFormat stringFormat = new StringFormat();
stringFormat.FormatFlags = StringFormatFlags.NoClip;
stringFormat.SetMeasurableCharacterRanges(characterRanges);
return stringFormat;
}

public void DrawText(double SampleTime, IntPtr pBuffer, int BufferLen)
{
Rectangle rec = this.ClientRectangle;

g = Graphics.FromImage(bitmapOverlay);
g.Clear(Color.Transparent);

g.SmoothingMode = SmoothingMode.HighQuality ;
g.TextRenderingHint= System.Drawing.Text.TextRenderingHint.AntiAlias ;

d = g.MeasureString(m_String, fontOverlay);

if (boolshadow == true)
{
SolidBrush myBrush = new SolidBrush (Color.Black );
g.DrawString(m_String, fontOverlay, myBrush, stringXPos + strshadow, stringYPos + strshadow);// System.Drawing.StringFormat.GenericTypographic

}
g.DrawString(m_String, fontOverlay, brush, stringXPos, stringYPos, System.Drawing.StringFormat.GenericDefault);

if (logo != null)
{
int xpos = (int)logoXPos;
int ypos = (int)logoYPos;
Rectangle dstRect = new Rectangle(xpos, ypos, logo.Width, logo.Height);

Rectangle r = Screen.PrimaryScreen.WorkingArea;
//MessageBox.Show(r.Width.ToString());
//MessageBox.Show(r.Height.ToString());

g.DrawImage(logo, dstRect,0,0, logo.Width, logo.Height, GraphicsUnit.Pixel, attr);
}
bitmapOverlay.RotateFlip(RotateFlipType.RotateNoneFlipY);
Bitmap v = new Bitmap(lWidth, lHeight, videoStride, System.Drawing.Imaging.PixelFormat.Format32bppPArgb, pBuffer);
g = Graphics.FromImage(v);
g.DrawImage(bitmapOverlay, 0, 0, lWidth, lHeight);
g.Dispose();
v.Dispose();
}

Printing is a little more involved. You need to have a PrintDocument and handle the PrintPage event.

Good C# Language Book

Haven't had much luck searching for this in the forums or online. I've done some programming in VB.NET and want to make the jump to C#. A lot of the beginning C# books are a little too introductory. I'm wondering if anyone has a recommendation for a book that is more focused on learning the language, syntax, and features of the language rather than a ground up intro to the .Net framework, OOP, etc... Any insight/recommendations would be greatly appreciated.

If in doubt use {}, end everything with ; and never ever captilize the first letter, ever Wink | ;)

Seriously though, if you're comfortable and familiar with the framework and concepts of OO it won't be that hard.

I have an idea to help though. The following is a pretty good code converter, try writing VB stuff and see how it looks in C#:

Doesn't do generics though.

Starting out with C++ by Tony Gaddis ISBN 9780321409393

This is what we used in college and has nothing about .NET and such (at least the older version anyhow. We used the 3rd edition but I know there has been at least one more edition since then.)

This is a great book for anyone who has little to no programming experience.

What I can say is "Dont even bother with C# Bible[^]"

It is a good example of what you don't want. It has a lot to say on OOP and the .NET Framework but very little on Socket Comms and doesn't even mention Marshalling.

I've found CodeProject to be of more help than this book.

Design question with message sending

Hello,

I have the following to do:

1) Windows Service which should provide some data to other applications...
2) application which handles this messages.

It is not so important that all messages comes to the applications...For that I thought about the possibility to use an udp socket.
What do you think about that? Is there a better possibility to send this messages in dotnet?

Best regards
Hansjörg
