Hello Doug Heimer,

Thank you for bringing this to our attention.
I'm glad to inform you that the leak have been fixed and the fix will be available in next beta or final release.

void CXTPFlowGraphPage::SetVisibleNodesWindowsRegions()
{
    ......

    if (bAtLeastOneWindowNode) // for optimization purposes
    {
        ......

        for (i=0; i<nodesWindowVisibleRegions.GetSize(); i++)
        {
            if (allNodes[ i]->GetWindowHandle())
            {
                .....

                SetWindowRgn(allNodes[ i]->GetWindowHandle(), nodesWindowVisibleRegions[ i], TRUE);
                
                //DeleteObject(nodesWindowVisibleRegions[ i]); // free-up resources
            }

            DeleteObject(nodesWindowVisibleRegions[ i]); // free-up resources
        }
    }
}

Regards,
 Oleksandr Lebed]]> Tue, 07 Mar 2017 15:28:09 +0000 http://forum.codejock.com/forum_posts.asp?TID=23113&PID=75606&title=solved-flowgraph-gdi-object-leak-17-2#75606 <![CDATA[[solved] Flowgraph GDI Object Leak 17.2 : CXTPFlowGraphPage::SetVisibl...]]> http://forum.codejock.com/forum_posts.asp?TID=23113&PID=75032&title=solved-flowgraph-gdi-object-leak-17-2#75032 Author: doug.heimer

CXTPFlowGraphPage::SetVisibleNodesWindowsRegions()


 

GDB Object Leak

 

       SetVisibleNodesWindowsRegions uses an optimization to perform rect region culling for child windows if any nodes the graph contain child windows exist.  In doing this, it calls CreateRectRgn for every node, regardless of whether that node has a child window.  However, only nodes with child windows have these regions released.  The rest leak.


Thanks,
Doug Heimer
