I assign image path to some string variable like this:

string path = "C:\at.jpg";

and apply this:

protected void Page_Load(object sender, EventArgs e)
{
Response.Write(@"<table border='1'>");
Response.Write(@"<tr>");
Response.Write(@"<td><img src=path></td>");
Response.Write(@"<td><img src='D:\try.jpg'></td>");
Response.Write(@"</tr>");
Response.Write(@"</table>");

I do not mean any control. I have to draw a table of 3 rows and 3 columns then i have to print image in every position of the table

Hi All!! I want to display images from the database into 3 x 3 table... The scenario is: 1. I have 3 x 3 table 2. Read Image from database. 3. Dispay it in the table How should i manage it?? I have done image reading from database but could not display it into the table...If i take image independently and display it on the web form then it goes ok but can't display in the table...guide me please!!

Hi All!! I am trying to display image from database on Asp.Net 2.0 Framework..But my problem is unsolved...The code is: protected void Button1_Click(object sender, EventArgs e) { string connectionString = "provider=Microsoft.Jet.OLEDB.4.0;" + @"data source=D:\\image\db.mdb"; OleDbConnection connection2 = new OleDbConnection(connectionString); string commandString = "Select Image from img where ImageCode = 1"; OleDbCommand command2 = new OleDbCommand(commandString, connection2); connection2.Open(); byte[] m_objBitmap = (byte[])(command2.ExecuteScalar()); ; connection2.Close(); Bitmap BitmapData = BmpDataFromBitmap(m_objBitmap); MemoryStream ms = new MemoryStream(); Response.ContentType = "image/jpeg"; BitmapData.Save(ms,ImageFormat.Jpeg); ms.Close(); } static public Bitmap BmpDataFromBitmap(byte[] BitmapData) { MemoryStream ms = new MemoryStream(BitmapData); return (new Bitmap(ms)); }

But i get error "Parameter is invalid" at line:

return (new Bitmap(ms)); I need your kind help..thanx!!

Hi Henry!! Thanks for your help...I searched that too...None of the article contains image encryption through RSACryptoserviceprovider. other CryptoServiceProviders are used...

I tried that but again

Bad Length

error is at:

byte[] encrypted = rsaCSP.Encrypt(toEncrypt, false);

Please help me out... :(

Hi All!! In code below, i'm encrypting bitmap(24-bit) image, accessed from ms-access database. Here is my code:

private void button1_Click(object sender, System.EventArgs e)
{
string connString = "provider=Microsoft.Jet.OLEDB.4.0;" + @"data
source=D:\\practiceproject\practice.mdb";
OleDbConnection connection = new OleDbConnection(connString);
string commandString = "Select Image from readImage where ID=1";
OleDbCommand cmd = new OleDbCommand(commandString,connection);
byte[] toEncrypt = new byte[120154];
connection.Open();
toEncrypt = (Byte[]) cmd.ExecuteScalar();
connection.Close();

		RSAParameters rsaPubParams;
		RSAParameters rsaPrivateParams;
		RSACryptoServiceProvider rsaCSP = new RSACryptoServiceProvider();
        
		//Generate public and private key data.
		rsaPrivateParams = rsaCSP.ExportParameters(true);
		rsaPubParams = rsaCSP.ExportParameters(false);
		rsaCSP.ImportParameters(rsaPubParams);

		byte\[\] encrypted = new byte\[130000\];
		encrypted =  rsaCSP.Encrypt(toEncrypt, false);

		//MemoryStream ms = new MemoryStream();
		//ms.Write(encrypted, 78, encrypted.Length - 78);	
	}

But i get

Bad Length

error at line

encrypted = rsaCSP.Encrypt(toEncrypt, false);

Please help me to resolve this problem!!!
