Re: Tracking the mouse CodeGuy23-Aug-01 11:00 CodeGuy 23-Aug-01 11:00  I believe you're looking for GetMouseMovePointsEx and GetLastInputInfo These are the key API calls that you will need; and of course, you'll need knowledge of the screen size using GetSystemMetrics. CodeGuy http://groups.yahoo.com/group/wtl Re: Tracking the mouse Bret Faller23-Aug-01 11:25 Bret Faller 23-Aug-01 11:25  Yeah, I've seen those functions but I need to continually monitor the mouse while my program is running, would that require another thread that only watches the mouse movements and what function would be a good place for these functions? Thanks for your response. Bret Faller Odyssey Computing, Inc. Re: Tracking the mouse CodeGuy23-Aug-01 11:31 CodeGuy 23-Aug-01 11:31  I don't think I would bother with a thread. I'd investigate just using a timer function (i.e. handling WM_TIMER), since nothing is time critical about checking for mouse movements.

Bret Faller Odyssey Computing, Inc. Re: Tracking the mouse Bret Faller23-Aug-01 11:46 Bret Faller 23-Aug-01 11:46  One problem, for some reason there is no such thing as MOUSEMOVEPOINT structure in my header files. Any ideas? I did a find in files search and got nothing. Bret Faller Odyssey Computing, Inc. Re: Tracking the mouse CodeGuy24-Aug-01 3:57 CodeGuy 24-Aug-01 3:57  Bret, I steered you wrong. The reason MOUSEMOVEPOINT is not available is because GetMouseMovePointsEx is a Win2000/Me API call. You would have to get the latest Platform SDK, but I suspect you would not want a solution for just those 2 operating systems. OK, well, this is more complicated, but you will have to do a Windows system hook to capture the mouse messages sent to the desktop.

Bret Faller Odyssey Computing, Inc. RIFF file parser Erik Hammar23-Aug-01 7:00 Erik Hammar 23-Aug-01 7:00  Does anybody know any free RIFF file parser? Not for any special RIFF sub-format, but one that can make the job of loading different RIFF files easier - in C++ preferrably Thanks, Erik Dundas - lack of information on updates - disruption of support 23-Aug-01 6:54 23-Aug-01 6:54  I have tried to mail Dundas because they have disruptet Hyperview Studio information from their web site. Actually I bought life time support and updates to this product a years ago. I cant even get access to the FAQ they provided before I mailed twice to hear what happened, but not even a reply. One thing is to sell life time upgrades a year before the product dies, not to answer questions about it seems for me to be bad bad. I also used to buy Ultimate Toolkit with updates every 14 days. But without any notice they stopped this service. Today I cant even get any information about errors ... updates .. Is it only me, a fault or .....

Re: change text color at runtime CodeGuy23-Aug-01 6:44 CodeGuy 23-Aug-01 6:44  OnCtlColor is one of a series of calls that will get made in response to a WM_PAINT event being fired. So how would you programmatically send an WM_PAINT to your CEdit? Call the Invalidate member function; this is available since CEdit derives from CWnd. This will force your edit control to be redrawn.

But I do not know how to show the object as a new toolbar in the frame window and how to attach a resource to my object. Please help. Thanks. Maer. Re: A Question About ToolBar Tomasz Sowinski23-Aug-01 7:33 Tomasz Sowinski 23-Aug-01 7:33  You should derive your class from CToolBar, not from CToolBarCtrl. CToolBar is designed to integrate into frame window architecture (docking/floating stuff). Tomasz Sowinski -- http://www.shooltz.com Re: A Question About ToolBar Maer72723-Aug-01 23:49 Maer727 23-Aug-01 23:49  Thanks for your reply. I find your reply very useful. I follow your methods, but still have a trouble. Here is my codes: //newtoolbar is a class member of the View class //based on a MDI program //"IDR_TOOLBAR1" is the resource id of the newtoolbar. newtoolbar.Create(WS_CHILD|WS_VISIBLE|CCS_TOP,CRect(0,0,100,100),(CMainFrame*)(AfxGetApp()->GetMainWnd()),IDR_TOOLBAR1); newtoolbar.ShowWindow(SW_SHOW); When running the program, the origin toolbar disappears and nothing is diaplayed in the origin toolbar position. How to resolve the porblem? Thanks. Maer Re: A Question About ToolBar Tomasz Sowinski23-Aug-01 23:58 Tomasz Sowinski 23-Aug-01 23:58  What happens if you change the 'newtoolbar' variable type to CToolBar? Tomasz Sowinski -- http://www.shooltz.com Re: A Question About ToolBar Maer72724-Aug-01 22:02 Maer727 24-Aug-01 22:02  Thanks for your reply. Your method really works well. Here is my source codes: //my program is based on MDI newtoolbar.Create((CMainFrame*)(AfxGetApp()->GetMainWnd()),WS_CHILD | WS_VISIBLE | CBRS_TOP,NEWTOOLBAR); newtoolbar.LoadToolBar(IDR_TOOLBAR1); ((CMainFrame*)(AfxGetApp()->GetMainWnd()))->RecalcLayout(); //where NEWTOOLBAR is the ID of the toolbar window, //newtoolbar is a data class member of the "View" class, //"IDR_TOOLBAR1 is" the resource id of the toolbar resource Thanks again.

Re: Confusion Christian Graus23-Aug-01 12:40 Christian Graus 23-Aug-01 12:40  There are so many places you can go - are you wanting to write console programs rather than Windows ones ? If not, then you need to get a good book on MFC. What you probably need to do is decide what sort of program you will write, choose something simple and then learn whatever you need to get it done.

Re: How to show a window in full screen? Aaron Schaefer23-Aug-01 6:43 Aaron Schaefer 23-Aug-01 6:43  Not too hard. Look at the documentation for CreateWindowEx. For window styles, pass WS_POPUP | WS_VISIBLE. For the window width and height, give it the width and height of the entire screen. You can call SetWindowPos to get it positioned at 0, 0. The window will occupy the entire screen. Re: How to show a window in full screen? CodeGuy23-Aug-01 6:58 CodeGuy 23-Aug-01 6:58  Also, more simply, use WS_MAXIMIZE for your window style. CodeGuy http://groups.yahoo.com/group/wtl Re: How to show a window in full screen? Tomasz Sowinski23-Aug-01 7:36 Tomasz Sowinski 23-Aug-01 7:36  If you want your mainframe class to go fullscreen (like VC++ IDE does), check the KB article Q164162.
