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)

cmd=new SqlCommand(sql_query,conn);<br />
cmd.ExecuteNonQuery();<br />
}<br />
catch(SqlException ae)<br />
{<br />
MessageBox.Show(ae.Message.ToString());<br />
}

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.

Hi, I'm wondering how I can remove the 'Close' button on a modal dialog. The reason is I don't want the user to accidentally close this partiulcar window, or at least display a confirmation to the user to ask whether if they really want to close it. I can't do that with the Form_Closing event as it stills closes it.

write your code int Dispose Method.e.g
protected override void Dispose( bool disposing )<br />
{<br />
<br />
if(DialogResult.Yes==MessageBox.Show("Do you Want to quit?","Quit",MessageBoxButtons.YesNo))<br />
{<br />
if( disposing )<br />
{<br />
if(components != null)<br />
{<br />
components.Dispose();<br />
}<br />
}<br />
base.Dispose( disposing );<br />
}<br />
else<br />
return;<br />
}<br />
|

When the Form is getting disposed it is already closed. So this doesn't work. Dispose is about freeing resources - no more no less.

Hi,
why can't you do this with the Closing event? This is exactly what it is meant for. Post some code. You have most probably some mistake in your code.

Robert, I don’t want say this but I have to say Check your Premise

|
|

Hi,
even after looking in a dictionary about premise I don't really get what you want to say. May be my mistake because english is not my native language. Could you reformulate?

You can. If the user doesn't want to close the form, assign true to the Cancel property of the passed CancelEventArgs instance.
