A couple things I see going on here. 1. You should verify pFlightDataHandler got created before using it. 2. I am assuming that the calls to getProcessStopEvent and getProcessRespEvent actually open a handle, otherwise, when you close them at the end of your thread, you have closed them off for the 'parent' as well. 3. It is not necessary to call AfxEndThread if you are going to exit the thread via its return. Just return the value 0 at end of thread function to accomplish same result. 4. I am assuming that pLogWriter's writeEntry will not throw exceptions, otherwise, you could just flag a problem in your exception handling code and then write to log after leaving the exception. 5. I would consider moving the CoInitialize ahead of your main try block, since the CoUninitialize is already outside of it. 6. If the pFlightDataHandler is a 'risky' object, consider putting its delete in a try/catch block. 7. Why not wait for 0 milliseconds, as per MSDN The function returns if the interval elapses, even if the object's state is nonsignaled. If dwMilliseconds is zero, the function tests the object's state and returns immediately. Then I think it might not even suspend your thread if the system is not busy. Otherwise, I am not sure why you would have a problem, unless one of your obejcts is bad, as there are a couple other retrieval functions there where the pointers are not verified against NULL.

I have re-posted this in the C++/MFC forum. I would move it if I could. Thanks.

Ok now that I'm caught up... :) Have you done everything required here[^]? Mark Mark Salsbery Microsoft MVP - Visual C++ :java:

Yes, I have tried starting the service from the services snapin, then attaching the debugger. It is always stuck in this loop waiting for a change in the current state. I have also stepped into the code from the Winmain entrance and it goes directly to this wait loop. However, I will have to wait until Monday as I can't uninstall the service remotely in order to restart it and I am not at my workstation. So I will pursue this then. Thanks for your help.

great, now we are going to have usb drive viruses. _____________________________ www.DaytonaForums.com

Thanks for the help, guys. I found that my problem was using the double quotes around the file paths and not specifiying a filename in the 2nd parameter. Royce

This is when the control is first displayed, so there is no previous item. Anyway, it appears that by default the first item is selected when the first expansion happens. It happens after the expansion is handled because there is no selection during the handling of the TVN_ITEMEXPANDED message. At any rate, I fixed the problem by adding a root item without any text. That root item gets selected, but because it has no text, it doesn't appear selected. Thanks for your help, Royce

You could try Doxygen. Steve

I have found a fix for this problem, but I can't as yet explain why it works the way that it does. I am now creating my ListCtrl like so: DWORD dwStyle = WS_CHILD | WS_TABSTOP; dwStyle |= LVS_ALIGNTOP | LVS_AUTOARRANGE | LVS_ICON | LVS_SHOWSELALWAYS | LVS_SINGLESEL; if ( bVisible ) dwStyle |= WS_VISIBLE; HWND hWnd = ::CreateWindow( "SysListView32", NULL, dwStyle, rcTree.left, rcTree.top, rcTree.Width(), rcTree.Height(), m_hWnd, NULL, AfxGetInstanceHandle(), NULL ); m_ctlComponents.Attach( hWnd ); Problem is fixed.

Rajesh, Thanks for your help. However, both of these articles (and all of the others that I have seen) address custom drawing in a report or list style CListCtrl, but not in an icon style control. I need to the behavior of the icon style, but with buttons instead of the icons. My application needs to allow a co-pilot or flight engineer to push a button with a gloved finger. Each button, when pushed will invoke functionality specific to the button. The bitmap button works well for this purpose as I need to change the button's appearance, i.e., bitmap, text, background color, etc., depending on the aircraft selected. (I have tried to put a screen shot here to show you, but couldn't get the GIF to show up.) Royce

Yes, I understand all that. It is the creation of the CFormview window that I am having trouble with. How and when do I create it? Must it be a child of a CFrameWnd? Can it be a child of another CFormView?

Handle this message for the button: ON_UPDATE_COMMAND_UI And write your enable disable code here. pCmdUI has got the necessary elements for this purpose: afx_msg void OnUpdateYourButton( CCmdUI* pCmdUI ); :) --Owner Drawn --Nothing special --Defeat is temporary but surrender is permanent --Never say quits --Jesus is Lord

Thanks, Nishant, for the help. However, the rect parameter is apparently ignored. This always docks the 2nd toolbar under the first one against the left frame border.

Yes, the resources are in the EXE. I have opened the EXE in binary mode with the IDE's resource editor and I can see them.
