ReadEventLog EventID 15-Oct-02 10:49 15-Oct-02 10:49  I'm having problems reading the proper EventID when reading the eventlog. Most of the Microsoft generated EventID's are OK, but some sources like Diskeeper will display as "1034662352" instead of "12" from the EventViewer. Any ideas? Here's a snippet of code that should give you an idea of what I'm doing... pevlr = (EVENTLOGRECORD *) &bBuffer; while (ReadEventLog(h, // event log handle EVENTLOG_BACKWARDS_READ | // reads forward EVENTLOG_SEQUENTIAL_READ, // sequential read 0, // ignored for sequential reads pevlr, // pointer to buffer BUFFER_SIZE, // size of buffer &dwRead, // number of bytes read &dwNeeded)) // bytes in next record { while (dwRead > 0) { printf("EventID: %d\n", pevlr->EventID); } pevlr = (EVENTLOGRECORD *) &bBuffer; } how to delete a file in code? ns15-Oct-02 10:18 ns 15-Oct-02 10:18  I have a database file that I want to delete if it already exists, so that I can create a new one with my code. I will have the path to the existing database available. How can I code so that it deletes the database if it exists? Appreciate your help, ns Re: how to delete a file in code?

But I also need to check that it exists. Or can I just blindly delete it even if its nonexistent? I think that might not work> Is there a FileExists kind og function thats available?

Thanks for the GetStatus. Hows the new project coming along? Appreciate your help, ns Re: how to delete a file in code? Ravi Bhavnani15-Oct-02 10:52 Ravi Bhavnani 15-Oct-02 10:52  ns wrote: Hows the new project coming along? Cool! Btw, contrary to what someone replied, you need to check if the file is readonly - if so, modify its attributes (use CFile::SetStatus) before deleting it - or at least warn the user. Damn, I reeeeely should post that FileSystem class at CP! Its deleteFile() method has a bool bForce arg that will take care of this. /ravi Let's put "civil" back in "civilization" http://www.ravib.com ravib@ravib.com Re: how to delete a file in code?

Don't worry about DeleteFile, it won't crash your program if the file doesn't exist...well maybe on 98 Chris Richardson Re: how to delete a file in code?

Quickie: Want control to lose focus Anonymous15-Oct-02 9:58 Anonymous 15-Oct-02 9:58  Whilst looking at my MFC CWnd window, I often just fiddle with the mouse wheel out of boredom.. however my window has a slider control class on it, and if I've just moved the slider then fiddling with the wheel will make it move. I would like to put in some kind of handler for the main CWnd so that if the user clicks anywhere in the window that isn't a control, the focus is given to the window and not the control. Which handler do I use? CWnd::OnMouseActivate() doesn't quite seem to work in the way I want... Thanks, ____________ Smidge Re: Quickie: Want control to lose focus Ravi Bhavnani15-Oct-02 10:40 Ravi Bhavnani 15-Oct-02 10:40  Hmmm, by wanting to have *no* child window have focus when the user clicks in an "empty" part of the window, you'll likely confuse your users by overriding Window's standard behavior (i.e. remembering which child window has focus). /ravi Let's put "civil" back in "civilization" http://www.ravib.com ravib@ravib.com Re: Quickie: Want control to lose focus Anonymous16-Oct-02 10:13 Anonymous 16-Oct-02 10:13  I'm aware of what the window behaviour would be like, but this would not cause major problems.. Do you know which message I should handle? Thanks, Re: Quickie: Want control to lose focus Ravi Bhavnani16-Oct-02 12:01 Ravi Bhavnani 16-Oct-02 12:01  I think you'd need to handle WM_SETFOCUS and WM_LBUTTONDOWN in PreTranslateMessage(). Good luck! I'd be curious to know how it works out. /ravi Let's put "civil" back in "civilization" http://www.ravib.com ravib@ravib.com which STL container can do this? ns15-Oct-02 9:53 ns 15-Oct-02 9:53  I dont want to have duplicate entries, but I dont want any sorting either. I was using a set but it wont work for me since it sorts. A vector doesnt sort, but allows duplicates. Is there a container that will neither allow duplicates, nor sort?

In other words, you search for an item before inserting a new item. Kuphryn Thank you all! ns15-Oct-02 10:20 ns 15-Oct-02 10:20  many thanks for the suggestions - I now have so many options!

Unfortunately, this container is not standard. I think STLPort has it, though. Check here[^] for info about hash_sets. Joaquín M López Muñoz Telefónica, Investigación y Desarrollo
