CDialogBar buttons. John Uhlenbrock23-Aug-01 7:22 John Uhlenbrock 23-Aug-01 7:22  I am unable to disable dialog bar buttons. No matter which button, or where I do it from, it enables itself right after I disable it. Any ideas? Re: CDialogBar buttons.

What is confusing you ? At this point I'd urge you not to even consider writing any windows programs - if you're at a stage of understanding classes you need to be writing console programs in order to learn these basics. A class is defined like this: class MyClass { } and can contain public, private and protected members. A member can be a variable or a function, so you might have this: class MyClass { public: int GetValue(); void SetValue(int val); private: int m_Value; } This is in your header file, the actual functions go into your cpp file like this: int MyClass::GetValue() { return m_Value; } void MyClass::SetValue(int val) { m_Value = val; } The example is a little contrived, but I really have no idea where your area of difficulty is. Please ellucidate, on a new thread where it belongs, and I'm sure that others as well as myself would be glad to help.

Tracking the mouse Bret Faller23-Aug-01 7:12 Bret Faller 23-Aug-01 7:12  I have a dialog based app that docks to the edge of the screen and auto-hides itself like the taskbar and I need to be able to tell when the mouse cursor hits the edge of the screen so I can restore my dialog. I've looked on MSDN but couldn't really find anything great, I know I can hack it and leave a corner of the dialog out and then show when the mouse enters (WM_MOUSEMOVE) but that isn't really what I want. Any help is greatly appreciated. Bret Faller Odyssey Computing, Inc. 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.
