Why don't you draw on a bitmap?
Bitmap bmp = new Bitmap(...);
Graphics g = Graphics.FromImage(bmp)
//... do the drawing
g.Dispose();

private Bitmap CreateNewBitmap(int width, int height)
{
Bitmap myBitmap = null;
// create a new bitmap with width and height of your chooise
using(Bitmap bmpNew = new Bitmap(width, height))
{
using(Graphics g = Graphics.FromImage(bmpNew))
{
RectangleF Destinationrectangle=new RectangleF(0,0,bmpNew.Width,bmpNew.Height);
RectangleF Sourcerectangle=new RectangleF(topleft,topright,bottomleft,bottomright);
g.DrawImage(this.BinaryImage.Image,Destinationrectangle,Sourcerectangle,GraphicsUnit.Pixel);
}
// Now create the new Bitmap
myBitmap = new Bitmap(bmpNew);

hi there,
I'm not sure what you're trying to do here. Do you actually need the relationships created between the tables or are you just trying to query data using joins. I believe that each DB engine will have a slightly different way of creating things like relationships.
this is the code for sql2000
ALTER TABLE Person
ADD CONSTRAINT Person_AddressID
FOREIGN KEY (AddressID)
REFERENCES Address(AddressID)

thanks buddy for the idea.
however i'm encountering another problem.
i'm using the following sql query to display all information of a table.
string table_name1=comboBox1.Text;<br />
string sql_query="DESCRIBE "+table_name1;<br />
<br />
try<br />
{<br />
cmd=new SqlCommand(sql_query,conn);<br />
cmd.ExecuteNonQuery();<br />
}<br />
catch(SqlException ae)<br />
{<br />
MessageBox.Show(ae.Message.ToString());<br />
}
the error i'm gettin is
could not find stored procedure 'DESCRIBE'
could u please guide me about this.
is there any error with the query??
i tried using the keyword DESC also but it still gives an error.
plz help
thanks

Sql Server doesn't have any defination for Desc or Describe .use following query to get column information of a table
SELECT Column_Name, Data_TYPE FROM Information_Schema.Columns WHERE (TABLE_NAME = 'TableName')

which database engine are you using? this kind of code is often very DBMS specific.
if you are using SQL and are never likely to point your code at any other dbms i would recommens using the SQL SMO objects

Hello yogita ,
It depands on your working scenerio.
If its just class with some methods to call then I suggest to Create instance in every aspx but please dispose that object too.
If that class contains session or user information then you may use in global class.
Thank You.
