Re: converting a console app to a MFC app adamUK22-May-03 9:16 adamUK 22-May-03 9:16  John, Probably the best bet is to use the MFC Appwizard in VC++. You can create dialogs and apps by widgets (controls) where you want them and write the code to handle them. Then just port your code across. Adam. My world tour What I do now..

CTreeView problem Shay Harel22-May-03 8:45 Shay Harel 22-May-03 8:45  Hi, I want to add a tree view to my Frame window. First I want to create a class that inherit from CTreeView, So I write: <br /> class CMyClass : public CTreeView<br /> {<br /> bla bla bla<br /> }<br /> I did it Using the Insert->New Class and so on, using the visual studio. When I compile, I get an error that the base class (CTreeCtrl) is not recognized.......... How come ? I have included stdafx.h in my application.... Shay Re: CTreeView problem peterchen22-May-03 9:17 peterchen 22-May-03 9:17  make sure #include <afxcmn.h> is in your stdafx.h, and add #include <afxcview.h> to it "Der Geist des Kriegers ist erwacht / Ich hab die Macht" StS sighist | Agile Programming | doxygen Re: CTreeView problem Shay Harel22-May-03 9:21 Shay Harel 22-May-03 9:21  Coooooooooollllllllllll !!! It works ! Thanks. BTW, My application is dialog based, when I created a window based I did not have this problem, what is the reason ? warning 4786 Makover22-May-03 8:40 Makover 22-May-03 8:40  Hello all, My project consists of about 50 files and on top of each file i declared: #pragma warning(disable : 4786) but I still get these long compiler warnings (17!). Any ideas why? Re: warning 4786 peterchen22-May-03 9:18 peterchen 22-May-03 9:18  Might be caused by an stdafx.h include - if you're using precompiled headers, basically everything above #include "stdafx.h" is ignored silently. add the warning(disable) to the stdafx.h, before you include any "offending" headers. "Der Geist des Kriegers ist erwacht / Ich hab die Macht" StS sighist | Agile Programming | doxygen Re: warning 4786 Makover22-May-03 9:24 Makover 22-May-03 9:24  ammm, I'm not sure I know what stdafx.h is. My guess is it has to do with MFC, however there is no useage of MFC in the project. Thanks. Re: warning 4786 peterchen22-May-03 9:55 peterchen 22-May-03 9:55  stdafx.h has nothing to do with MFC, it's the standard header file used for precompiled header support in VC (most project wizards create one automatically, and set up the project accordingly). Look in your Files tab if a stdafx.h is part of your project. If so, put the #pragma above the first #include. "Der Geist des Kriegers ist erwacht / Ich hab die Macht" StS sighist | Agile Programming | doxygen Re: warning 4786 David Crow22-May-03 9:53 David Crow 22-May-03 9:53  Are you being affected by: For warning numbers greater than 4699, those associated with code generation, the warning pragma has effect only when placed outside function definitions. The pragma is ignored if it specifies a number greater than 4699 and is used inside a function. If not, then MSDN article Q167355 is most likely the problem. Re: warning 4786 Makover22-May-03 10:05 Makover 22-May-03 10:05  My mistake: I put the pragma declaration after the include directives. Putting it before anything else made the trick. Thanks for your help. CSplitterWnd with CWnd as a pane adamUK22-May-03 8:18 adamUK 22-May-03 8:18  MSDN says you can have a CView or a CWnd as a pane in CSplitterWnd. CView is sorted but how do I create using a CWnd? There seems no equivalent to the CSplitterWnd::CreateView for CWnds. cheers!! Adam. My world tour What I do now..

Re: CSplitterWnd with CWnd as a pane peterchen22-May-03 9:20 peterchen 22-May-03 9:20  See http://www.cherea.de/bitbucket/multisplitwnd/multisplitwnd.html[^] for a CSplitterWnd dereived class that a) demonstrates this and b) also has ann AddView(CWnd *) method.

Re: Dialog David Crow22-May-03 7:28 David Crow 22-May-03 7:28  If you are using MFC, see this FAQ: http://www.codeproject.com/cpp/cppforumfaq.asp#mfc_dlgclosekeys Clickety adamUK22-May-03 7:32 adamUK 22-May-03 7:32  http://www.codeproject.com/cpp/cppforumfaq.asp#mfc_dlgclosekeys[^] My world tour What I do now..

Re: Dialog adamUK22-May-03 7:31 adamUK 22-May-03 7:31  You could always override CDialog::OnOK() but that would also stop the OK button from making your dialog disappear. Adam.

Re: Dialog Ravi Bhavnani22-May-03 7:53 Ravi Bhavnani 22-May-03 7:53  Also, don't forget to override OnCancel() if you don't want the dialog to disappear when the user presses Esc. /ravi Let's put "civil" back in "civilization" Home | Articles | Freeware | Music ravib@ravib.com Re: Dialog adamUK22-May-03 8:13 adamUK 22-May-03 8:13  Hmm..kinda wondering how to stop the enter button but still enable the Ok button (okay, I guess I could hide the default OK button, create a new one that does all the stuff but I think it is cheating....) any thoughts?

Re: Dialog Ravi Bhavnani22-May-03 8:19 Ravi Bhavnani 22-May-03 8:19  I just delete the default (not hide) OK button and create a new one. Alternatively, you could override PreTranslateMsg() and catch the Enter keystroke there. I prefer the former way. /ravi Let's put "civil" back in "civilization" Home | Articles | Freeware | Music ravib@ravib.com Re: Dialog adamUK22-May-03 8:28 adamUK 22-May-03 8:28  I was fiddling around with PreTranslateMessage to see if I could get it to work but I agree with you. The first way you mentioned is the way I have always done it and it still seems the simplest! thanks! Adam. My world tour What I do now.. "I spent a lot of my money on booze, birds and fast cars.

Re: Dialog jia_wei22-May-03 18:45 jia_wei 22-May-03 18:45  one method is to rename the ID of button "OK",don't use IDOK. another method is to define a function for press button "OK",in the function, delete the line"CDialog::OnOk(). Cast operator example? Ravi Bhavnani22-May-03 7:18 Ravi Bhavnani 22-May-03 7:18  I've lost my mind and can't remember how to implement a cast operator. A gentle nudge would be appreciated. I want to implement a (bool) operator for a CFoo object, so I can do things like: CFoo myFoo; bool myBool = myFoo; CFoo myFoo; if (myFoo) { ... } Thanks, /ravi Let's put "civil" back in "civilization" Home | Articles | Freeware | Music ravib@ravib.com Re: Cast operator example? David Crow22-May-03 7:30 David Crow 22-May-03 7:30  You failed to say if it was even safe to cast a CFoo object to a bool. Assuming it is, then bool myBool = (bool) myFoo; will work fine.
