copied!<p><strong>Backgroud:</strong><br> I'm now trying to print via <a href="http://msdn.microsoft.com/en-us/library/windows/desktop/ff686799%28v=vs.85%29.aspx" rel="nofollow">GDI Print API</a>, and it looks like this:</p> <pre><code>StartDoc(hDC,&docinfo) foreach page in page_buf StartPage(hDC) /* write the page to printer DC */ EndPage(hDC) EndDoc(hDC) </code></pre> <p><strong>The Problem:</strong><br> During printing there would be a notification area icon, and by clicking on it there would be a small window showing current printing jobs on a specified printer.<br> By right-clicking on a printing job and choosing <code>Cancel</code>, a printing job shall be cancelled. But my application continues sending data to the printer DC until all pages are processed, and the status keeps showing <code>Deleting - Spooling</code> before it finishes.<br> What I want is to stop the printing procedure right after choosing to cancel it.</p> <p><strong>What I've tried:</strong><br> 1. First I thought the device content would get invalid after cancelling the job (that's of course not true), and tried to examine the return values of <a href="http://msdn.microsoft.com/en-us/library/windows/desktop/dd145116%28v=vs.85%29.aspx" rel="nofollow"><code>StartPage</code></a> and <a href="http://msdn.microsoft.com/en-us/library/windows/desktop/dd162596%28v=vs.85%29.aspx" rel="nofollow"><code>EndPage</code></a>. Then I found they both don't fail after the cancellation of printing job.<br> 2. I've also tried <a href="http://msdn.microsoft.com/en-us/library/windows/desktop/dd162960%28v=vs.85%29.aspx" rel="nofollow"><code>SetAbortProc</code></a> and <a href="http://msdn.microsoft.com/en-us/library/windows/desktop/dd183575%28v=vs.85%29.aspx" rel="nofollow"><code>DocumentEvent</code></a>, and found they're not what I want.</p> <hr> <p>But I suppose there shall be some mechanism to indicate my application when the printing job is cancelled. It would be appreciated if someone tries to help.</p>
