Think Packet-sniffer. ...Promiscuous Mode is a networking term where your network hardware is actively listening for broadcast messages that aren't necessarily directed at it. To answer OP's question: I'm not telling

...crap. I woulda been in before anybody else, but my boss came by and needed me in a meeting lol.

So you want to sniff the network, but you can't figure out how to do it yourself?

There are several articles on "network sniffer" here on CP.
I guess they contain what you need. Did you look at them ?

You would do better by using a trusted connection and setting up in SQL Server the windows accounts that are permitted to access the database.

//I have a problem with saving data from datasetts back to database, please help me. Im using mysql connector but work with mysql amd mssql is very similar (i think )
//First i create a data adapter (reading data is ok):

cmd = new MySqlCommand("UPDATE " + pfx + "module_discussion_posts SET poster_name=?name, poster_email=?mail, subject=?subject, message=?message WHERE idpost=?oldId;", conn);

this.idpost.DataBindings.Clear(); // setting dataset for text box
this.idpost.DataBindings.Add(new Binding("Text", postsDS, "module_discussion_posts.iddiscussion"));
// third ... when i change datas in data set i want to save this changes back to database ... but its nt working ... pleeeeeeeeeease help me

I don't use DataAdapters much, and never MySql, so I may be way off base:
In the first part you create a DataAdapter and then set its commands.
Unless you really need to customize the UpdateCommand you probably ought to use
MySqlDataAdapter da = new MySqlDataAdapter ( selectcommandtext ) ;
In the second part I see no need for the CommandBuilder.
I also tend not to use a DataSet to hold just one DataTable, but that's just me.
Then in the third part you should only need the
postsDA.Update(this.postsDS, "module_discussion_posts");

its not working, its same code what i have but im using another way to create data adapter

You can use
Encoding.[UTF7/UTF8/etc].GetByte(String param)
and viceversa
Encoding.[UTF7/UTF8/etc].GetString(byte[] b)
to convert method to/from byte to string and viceversa than save it in registry.

Hi all,
I'm trying to highlight spesific word inside a cell on any cell within a datagridviewcontrol, to do this i have write a special code inside OnCellPaint method
string v = e.FormattedValue.ToString().ToLower();
int idx = v.IndexOf(searchWord.ToLower());
if (idx != -1)
{
System.Drawing.Font ff = e.CellStyle.Font;
// get a length word before searchWord/highlightWord
int addx = e.Graphics.MeasureString(e.FormattedValue.ToString().Substring(0, idx), ff).ToSize().Width;
// get a length searchWord
int w = e.Graphics.MeasureString(e.FormattedValue.ToString().Substring(idx, searchWord.Length), ff).ToSize().Width;
// draw highlight background
Brush br2 = new SolidBrush(blockColor);
e.Graphics.FillRectangle(br2, new Rectangle(e.CellBounds.X + addx, e.CellBounds.Y + 1, w, e.CellBounds.Height - 3));
homever measurestring didn't return correct size from current cell text, therefore highlighted background didn't placed on right position. This code also doesn't work on cell with currency formatted cell because currency cell is rightalignment. My question is how do i get correct size in pixel from current cell text using measurestring ? Because measurestring combined with e.cellstyle.font didn't return correct size.

MSDN says: "The MeasureString method is designed for use with individual strings and includes a small amount of extra space before and after the string to allow for overhanging glyphs. Also, the DrawString method adjusts glyph points to optimize display quality and might display a string narrower than reported by MeasureString. To obtain metrics suitable for adjacent strings in layout (for example, when implementing formatted text), use the MeasureCharacterRanges method". It might help ...

To validate comma separated values you just have to use a repeating pattern.
For a simple example, to verify a string of comma separated characters "a,b,x,y,z", you can use a pattern like "[a-z](,[a-z])*". To use it with email addresses, just substitute the [a-z] set with the pattern for an email address.

Hi,
The requirement is that the end user would upload an image to the application, the uploaded image should be modified with a watermark and then be saved in our application. Kindly guide!!!
Thanks!!

I'd suggest reading my image processing articles for info on how to access the pixels of a bitmap, then work out what sort of watermark you want to add. Assuming you don't just want to add a bitmap in the corner or something simple.

A method like this may do the job, if you just want to add text to the image: (you'll need to include the System.Drawing reference and namespace)
Bitmap AddWaterMark(Bitmap uploadedBitmap)
{
Bitmap newBitmap = new Bitmap(uploadedBitmap);
Graphics g = Graphics.FromImage(newBitmap);
g.RotateTransform(45); // Angle of text
g.DrawString("Watermark Text",
new Font("Arial", 12f),
new SolidBrush(Color.FromArgb(100, Color.Black)), // the 100 is for transparency (0 = invisible, 255 = opaque)
new Point(100,100));
return newBitmap;
}
