also add this line inside the loop if you want to form to be responsive and the user able to click the stop button<br />
unless you are running the loop in another thread other than the main application thread.<br />
<br />
while (objRdr.Read() &amp;&amp;&nbsp;!stop)<br />
{<br />
&nbsp; &nbsp; //Do your work<br />
&nbsp; &nbsp; System.Windows.Forms.Appli<wbr />cation.DoE<wbr />vents();<br />
}<br />

If your process of executing the query is very cpu intensive then i suggest you invoke this on a separate thread..this way you have 2 ways of stopping the process<br />
<br />
a) Kill your sub thread &nbsp;by calling abort() or join()<br />
b) as anarki_jimbel said update a string variable value and you can check it each time as mohzedan said

Executing the query

C# is an object-oriented programming language created in conjunction with Microsoft’s .NET framework. Compilation is usually done into the Microsoft Intermediate Language (MSIL), which is then JIT-compiled to native code (and cached) during execution in the Common Language Runtime (CLR).
