Tray Icon vijayaramaraju12-Jul-01 18:52 vijayaramaraju 12-Jul-01 18:52  Hi , I've Created an application that puts up an icon in the system tray. If I close that application by sending WM_CLOSE or WM_QUIT messages from another application the tray icon disappears normally ,but if i use terminate process from another application the tray icon remains until I move the Mouse Pointer above the Icon after which it disappears Is there anyway to refresh the system tray ??? Please help out Re: Tray Icon Michael Dunn12-Jul-01 19:18 Michael Dunn 12-Jul-01 19:18  As MS would say, that behavior is by design. The tray icons don't do anything until you move the mouse over them. --Mike-- http://home.inreach.com/mdunn/ Sometimes, arming yourself with a big pointy stake just won't do you any good. COleCurrency otvac12-Jul-01 15:01 otvac 12-Jul-01 15:01  Duh! How in the world do you get a COleCurrency object to look like money with 2 decimal places (in an edit box, for example)? I feel really stupid having to ask this one. Please be gentle! Richard Re: COleCurrency Tomasz Sowinski13-Jul-01 0:11 Tomasz Sowinski 13-Jul-01 0:11  COleCurrency::Format doesn't work? Tomasz Sowinski -- http://www.shooltz.com Pointer to CListCtrl Frank Deo12-Jul-01 13:59 Frank Deo 12-Jul-01 13:59  I have created a docking window. And, in the docking window created a listctrl. I can add items to the list control from within the Create function in my docking window class. No problems there. However, when I try to add an item to my list control from a menu command within my MainFrame class it fails in IsWindow(m_hWnd). How can I get a valid pointer to my list control so that I can add items to it without failing because of an invalid window handle? Thanks, Frank transparent static control problems stephen.hazel12-Jul-01 12:35 stephen.hazel 12-Jul-01 12:35  I've set up a bitmapped background for my Win32 (no MFC) dialog based app. The dialog handles WM_CTLCOLORSTATIC by - SetBkMode (hdc, TRANSPARENT); - return GetStockObject (NULL_BRUSH); This -does- let the background show thru like I want.;) BUT, when I update the static controls' text, the old foreground is left and the new foreground text is stamped on top of it makin a MESS. Someone else MUST have run across this, right? Could ya help me out? Thanks! ...SteveH http://hazels.freeservers.com Re: transparent static control problems Michael Dunn12-Jul-01 12:39 Michael Dunn 12-Jul-01 12:39  Invalidate the control after changing the text, so the entire control will repaint. --Mike-- http://home.inreach.com/mdunn/ Push the button, Frank. Re: transparent static control problems stephen.hazel12-Jul-01 13:04 stephen.hazel 12-Jul-01 13:04  Rats. Didn't work after all... I'm doin this: ::SendMessage (statctl, WM_SETTEXT, (WPARAM) 0, (LPARAM) txt); ::InvalidateRect (statctl, NULL, TRUE); I would think that SendMessage would already invalidate the whole control...? Either the background ain't gettin erased by the dialog's WM_ERASEBKGND or the control is getting it's draw messages messed up or somethin??? One last thing - should I be invalidating the whole dialog when I need to change the static's text? Thanks for the help tho! I could send you my src if that'll help... ...SteveH http://hazels.freeservers.com Re: transparent static control problems 12-Jul-01 14:10 12-Jul-01 14:10  Did you try to call UpdateWindow(statctl); after that?? Mh2! Registering file types that aren't doc/view types 12-Jul-01 11:33 12-Jul-01 11:33  Here’s my scenario: I have an application that can save/load project files. I want to be able to register the icon and file extension (*.kkp) with the system so that you can open them directly from within Explorer, and have my app load, but not try to load the project as a document. Instead, I need to be able to detect the file is a project file and then handle it myself. I know this is possible – I even managed to do it in a previous app I was working on, but now I can’t remember how to do it. Can anybody help? Yours, Peter P.S. Sorry for posting this again, but it got buried under a whole load of other questions as soon as In asked it! Re: Registering file types that aren't doc/view types Michael Dunn12-Jul-01 15:13 Michael Dunn 12-Jul-01 15:13  All Explorer does is run your app with the filename as a command line parameter (or whatever you set in the ...\shell\open\command key). How you handle things once you get the filename is up to you. There's nothing requiring you to handle the file as a document. --Mike-- http://home.inreach.com/mdunn/ Sometimes, arming yourself with a big pointy stake just won't do you any good. HURGENT !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! 12-Jul-01 10:48 12-Jul-01 10:48  I have editBox (read only) with spin. the variable of the editBox is int in range 10 - 2000 and the range of the spin is same. and all is right. But when the user try to up the number in the editBox over 999 he gets a error messageBox: "Please enter an integer." WHY ????????????????????????????????????????????????? _____________________________________________________________ I ask you about it already and Michael Dann answer me so: Uncheck the No Thousands property of the spin control - this prevents the control from adding a thousands separator (period or comma) to the number. _____________________________________________________________ But I did not understand this answer. Please HELP Re: HURGENT !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! 12-Jul-01 11:18 12-Jul-01 11:18  I guess it must be trying to put 1,000. "," is not an integer. What Michael Dunn is suggesting is to uncheck that option. Enabling a button.

Michael Dunn12-Jul-01 19:16 Michael Dunn 12-Jul-01 19:16  IE 5 already has this built-in. You can save a web page as an .MHT file, which contains everything on the page. If you need to do this programatically, look into the IE automation interface docs, and see if saving to .MHT via automation is supported. --Mike-- http://home.inreach.com/mdunn/ Sometimes, arming yourself with a big pointy stake just won't do you any good.

Exception Question 12-Jul-01 8:07 12-Jul-01 8:07  I have just started using exceptions, catching both built in types and defined objects. However, as I see it it would be very rare that I actually have a use for doing this. There is always a way around it, usually just error checking. I recall from using java that there are special types defined such as ArrayOutOfBoundsException which you can catch- these types also have relevant methods inluded for diagnosing and working with the exception. Is there no similar concept apart from std::exception... Thanks in advance..
