Re: Win32, ATL, WTL or MFC, which route to take? Michael Dunn5-Jul-02 12:08 Michael Dunn 5-Jul-02 12:08  Well, the fact that WTL got a major rev a few weeks ago puts Dunlap's statement down. WTL is not built on COM. It is built on the ATL windowing classes, so you need to know how those work. Here's a quick lesson: CWindow: wraps an HWND CWindowImpl<>: implements message handling There you go The message map macros and handlers are slightly different, but all that is documented. Check out my hotfix checker for a full-fledged app that uses WTL. --Mike-- Just released - RightClick-Encrypt v1.3 - Adds fast & easy file encryption to Explorer My really out-of-date homepage Sonork-100.19012 Acid_Helm Re: Win32, ATL, WTL or MFC, which route to take? generic_user_id5-Jul-02 23:29 generic_user_id 5-Jul-02 23:29  It does sound very promising, I must admit. Are there any good books which cover the WTL basics? And should I learn something about ATL first, or isn't that required? I'll check out your hotfix checker, but it won't work on a 98 system...

Re: Win32, ATL, WTL or MFC, which route to take? loket5-Jul-02 12:01 loket 5-Jul-02 12:01  I would definitly not go with straight Win32. MFC i dont like either, good as long as you stay on the 'mainroad', but if you try something else wierd things happens. And it does not work to well with threads. I suggest the WTL route. Ok, it is not documented or supported, but it builds on top of ATL and ATL is both documented and supported. There are documentation and samples for WTL on the net, and you dont really need that much documentation of WTL since it is a thin wrapper around Win32 windowing. And what support do you need, you have the source. I have switched from MFC to WTL, and with MFC there was *always* wierd things going on behind the scenes, with WLT everything works lika a clock. / - Don't sweat the petty things, and don't pet the sweaty things. Re: Win32, ATL, WTL or MFC, which route to take? generic_user_id5-Jul-02 23:34 generic_user_id 5-Jul-02 23:34  Yep, all the MFC majicks can be annoying. You mentioned there is documentation and samples for WTL on the net. Do you happen to have a few links outside of CP or CodeGuru? Just wondering, I'm sure the more professional programs of MS aren't written with MFC. (IExplorer, Word, Powerpoint) Do those program use a framework?

Processing GPS data in C++ 5-Jul-02 4:41 5-Jul-02 4:41  Anyone have a routine for reading in the standardGPS data in the NIMA format? I want to be able to read in the GPS data on a pocket PC with an application written in VC++ (embedded 3.0). AN SDK with a few objects for parsing the data would be perfect but any help in reading the serial port as well would be better... Thanks disabled menu item at start ns5-Jul-02 3:36 ns 5-Jul-02 3:36  I have two handlers for the two messages available for a menu item (command and command_ui..) These are like: void CFormViewMDIDoc::OnEnabledByadmin() { // TODO: Add your command handler code here //AfxMessageBox"hello"); } void CFormViewMDIDoc::OnUpdateEnabledbyadmin(CCmdUI* pCmdUI) { // TODO: Add your command update UI handler code here pCmdUI->Enable(m_checked) ; pCmdUI->SetCheck(m_checked); } I read that the menu item is initially disabled if theres no command handler for the menu. Even if I uncomment the messagebox in the command handler above, the menu item is still greyed out at startup. WHy is this? Thank you, ns Re: disabled menu item at start Fredrik Skog5-Jul-02 3:55 Fredrik Skog 5-Jul-02 3:55  You might want to have a look at the value of m_checked.

You were right! I'd set it to False in my constructor of the view class. I also see now that an uninitialized BOOL is TRUE by default. I wasnt sure what made UIUpdate function run automatically so I didnt connect things. Thanks for clearing that up! So the constructor makes the UI handler run too...right? Re: disabled menu item at start Roger Allen5-Jul-02 4:08 Roger Allen 5-Jul-02 4:08  No the constructor does not. MFC periodically calls the UI handlers for toolbar buttons and menu items when in the idle state, or when a menu is about to be shown. Roger Allen Sonork 100.10016 If I had a quote, it would be a very good one. Re: disabled menu item at start Fredrik Skog5-Jul-02 4:12 Fredrik Skog 5-Jul-02 4:12  If you have a look at the message map you'll see something like this: BEGIN_MESSAGE_MAP(CMainFrame, CFrameWnd) //{{AFX_MSG_MAP(CMainFrame) ON_UPDATE_COMMAND_UI(ID_INDICATOR_YOURFUNC, OnUpdateYourFunc) //}}AFX_MSG_MAP END_MESSAGE_MAP() There is a lot of stuff taken care of for you, so you don't see everything that is going on behind the curtains.

No it's not. An uninitialised BOOL, or an uninitialised anything else, is undefined. An uninitialised variable will have an indeterminate value - you can't rely on it. I believe that in debug builds the compiler will assign special guard values (which are non-zero, and hence considered to be 'true') as soon as it allocates memory (i.e. before you initialise it), but that's only the case for debug builds and you should never rely on it anyway. "We are the knights who say Ni" (The Knights Who Say Ni) MDI doc sending info to modal dlg -how to? ns5-Jul-02 3:24 ns 5-Jul-02 3:24  Well, in the modeless dialog spawned by my docs menu, I have access to a customizable Create function so I can send over info to the dlg window - like doc members etc(theoretically - am going to try it) How do I give the modal dlg a doc member value? I cant get the pDOc pointer and access it that way, or can I ? I suspect not since its not a view thats making the pointer (only place I've seen pDoc->GetMember() type stuff. Is it true that you can call this from any class where you instantiate the pointer, or only from the view, since its the only one who knows which doc to get the pointer to, and GetDocument is a View function. Thank you, ns Re: MDI doc sending info to modal dlg -how to? Mike Upton5-Jul-02 4:59 Mike Upton 5-Jul-02 4:59  Any particular reason you can't pass a pointer to the document to the Create function? Or, for that matter, to the constructor? Then you can store the document pointer in your dialog, and Bob, as they say, is your green alien-like Uncle. "We are the knights who say Ni" (The Knights Who Say Ni) Re: MDI doc sending info to modal dlg -how to? nsns5-Jul-02 16:24 nsns 5-Jul-02 16:24  Well, The way I've seen it, modeless dlgs get created with Create, but modal is just CMyDialog dlg; dlg->DoModal(); So theres no create function that I can see invoked for it. I'm new at this stuff so I can only base my info on stuff I see in books etc. Where d oes create() come in for a modaldlg? Thanks, and sorry if I seem clueless.... ns I get the pass in constructor idea....thanks! nsns5-Jul-02 16:26 nsns 5-Jul-02 16:26  I reread your response and think I can do what you say - sending it in via a constructor,. So sorry to be so hasty in my first reply (though I still dont see the Create conection) Re: I get the pass in constructor idea....thanks! Mike Upton7-Jul-02 22:28 Mike Upton 7-Jul-02 22:28  Apologies - I slightly misread your first message, and thought you were talking about modeless dialogs all the way through, not just in the first paragraph. You're right, Create() isn't used for modal dialogs.

I face a problem, that when 2 controls overlap each other and if they are selected( in other words they are showing the tracker) then the CRectTracker get hidden in the overlapping place. Please can someone tell me the solution on how to overcome this.
