Re: A CFileDialog Question - selecting multiple files PJ Arends11-Jan-02 6:13 PJ Arends 11-Jan-02 6:13  From MSDN <quote> To allow the user to select multiple files, set the OFN_ALLOWMULTISELECT flag before calling DoModal. You need to supply your own filename buffer to accommodate the returned list of multiple filenames. Do this by replacing m_ofn.lpstrFile with a pointer to a buffer you have allocated, after constructing the CFileDialog, but before calling DoModal. Additionally, you must set m_ofn.nMaxFile with the number of characters in the buffer pointed to by m_ofn.lpstrFile. </quote> --- Sonork 100.11743 Chicken Little It may be that your sole purpose in life is simply to serve as a warning to others. Reload Icon when Explorer Crashes Jason Hooper9-Jan-02 23:30 Jason Hooper 9-Jan-02 23:30  Can someone point me in the right direction? The only way to access my app is via its tray icon. When Explorer does the nasty, it takes all the icons down with it. How can I detect that it has crashed and that my app needs to reinstall its icon? I'm using Chris' CSystemTray, and PJ's CInstanceChecker, and Windows 98 (if that helps). Thanks. -Jason nirgle.bitdevil.com Re: Reload Icon when Explorer Crashes Nish Nishant10-Jan-02 0:31 Nish Nishant 10-Jan-02 0:31  In Win 2K when explorer crashes [that's rare, very rare] it has the decency to bring back all the icons on the task tray I guess what the user could do is to run your program again and your program can check for an earlier version using a mutex and then re-add the icon to the tray. You can check for its existence by sending a NIM_MODIFY message and if it fails it means the icon is not there [I hope so] Nish Sonork ID 100.9786 voidmain www.busterboy.org If you don't find me on CP, I'll be at Bob's HungOut Re: Reload Icon when Explorer Crashes Bill Leibold10-Jan-02 7:53 Bill Leibold 10-Jan-02 7:53  Not true.

Re: Reload Icon when Explorer Crashes Jon Hulatt10-Jan-02 0:57 Jon Hulatt 10-Jan-02 0:57  personally, i'd install a timer, and in the timer proc (attempt to) remove the icon and reinstall it again. doing this every 5 seconds or so won't take much cpu time and should work ok. Sorry to dissapoint you all with my lack of a witty or poignant signature. Re: Reload Icon when Explorer Crashes James R. Twine10-Jan-02 4:49 James R. Twine 10-Jan-02 4:49     How about doing it the way that Microsoft recommends...    Look up the "TaskbarCreated" registered message (requires that IE 4.0 or greater is installed).  It is sent by Explorer whenever the Taskbar is (re)created, so if Explorer crashes and restarts, your app will get sent the message, and can re-add its icon.    This is the way Services can install an Icon to the Taskbar's Status Area* when someone logs on.    * Calling it a "Tray Icon" is a common mistake.    Peace! -=- James. Re: Reload Icon when Explorer Crashes Jason Hooper10-Jan-02 7:14 Jason Hooper 10-Jan-02 7:14  Thanks for the response; I'm looking into it now. And, what's the best way to crash Explorer (besides using it normally)? Gotta love testing -Jason nirgle.bitdevil.com Re: Reload Icon when Explorer Crashes James R. Twine10-Jan-02 8:13 James R. Twine 10-Jan-02 8:13  > And, what's the best way to crash Explorer (besides using it normally)?    On NT/Win@K, Task Manager, Processes tab, select Explorer, right-click and select End Process.    On Win9x, CTRL-ALT-DELETE, (while the task list dialog is up, click on the Explorer window (the desktop) a few times for about 5-10 seconds, and select Explorer int the dialog and try to end it. You should get the end task dialog for Explorer.    Peace! -=- James. Re: Reload Icon when Explorer Crashes Michael Dunn10-Jan-02 7:48 Michael Dunn 10-Jan-02 7:48  James R.
