The third item should be labelled "Generate Preprocessed File". You click in that and drop the combo down to see the options.

Re: VStudio setting to see macro expansion? lucy3-May-02 7:11 lucy 3-May-02 7:11  I did a Project->Settings->C/C++ -> Category: Preprocessor, and what I see is: Preprocessor definitions (edit box) UnDefined symbols: (check box, followed by an edit box) Additional include directories: (edit box) Ignore standard include paths (check box). What did I miss? Re: VStudio setting to see macro expansion? Tom Archer3-May-02 7:18 Tom Archer 3-May-02 7:18  Oh. Are you running VS6? I'm running VS.NET. If you're running VS6, what you need to know is the following: Create preprocessor file - add /P to the CL call Create preprocessor file (with line numbers) - add /EP and /P to the CL call Therefore, either look through for the pages for this option or manually add it.

Re: VStudio setting to see macro expansion? lucy3-May-02 7:39 lucy 3-May-02 7:39  got it. Thank you, Tom. In VS6, it's add /P or /EP (output is the output window of VS6) in Project Options of Project->Settings->C/C++ ->Category: Preprocessor. Re: VStudio setting to see macro expansion? Tom Archer3-May-02 10:08 Tom Archer 3-May-02 10:08  No problem, Lucy. This is tremendously valuable in learning how those magic MFC and ATL macros work.

Re: VStudio setting to see macro expansion? hiseldl3-May-02 7:30 hiseldl 3-May-02 7:30  the Property Pages, do you mean Project->Settings from the main menu? Also, I am using VStudio 6 Enterprise Edition, if that helps. .dave. David Hisel -- http://www.hisel.com/ Re: VStudio setting to see macro expansion? Tom Archer3-May-02 7:35 Tom Archer 3-May-02 7:35  Sorry. I use VS.NET and forget that most don't. Look at my response to Lucy where I explain (as well as I can withouut the VS6 environment installed) how to do this in VS6.

Aoife3-May-02 5:08 Aoife 3-May-02 5:08  Hello, In my MFC application I have two similar dialog boxes. Each have a List Control Box and each has a varaible (of type CListCtrl) associated to them. One of them works fine but I get a Debug Assertion error on the first of these four lines in the second dialog. m_MyListControl2.InsertItem(0, Line1, 0) m_MyListControl2.SetItemText(0, 1, Line2); m_MyListControl2.SetItemText(0, 2, Line3); m_MyListControl2.SetItemText(0, 3, Line5); The dialog boxes all have the same header files and the contents of DoDataExchange() are similar too. Does anyone know why this is happening? Thanks, Aoife Re: Debug Assertion? mystro_AKA_kokie3-May-02 5:17 mystro_AKA_kokie 3-May-02 5:17  if you didn't make those calls in OnInitDialog then it's because they haven't been created yet. Re: Debug Assertion? Aoife3-May-02 5:31 Aoife 3-May-02 5:31  But the first dialog box isn't mentioned in OnInitDialog and it works fine. Could it be because there is two of them? Thanks, Re: Debug Assertion? Tim Smith3-May-02 5:30 Tim Smith 3-May-02 5:30  What does the debug assertion say. Not only does it usually print text about why it asserted, but if you look at the source code where the assert was raise, it sometimes gives you information about what you need to do to correct the problem. Tim Smith I know what you're thinking punk, you're thinking did he spell check this document? Well, to tell you the truth I kinda forgot myself in all this excitement. But being this here's CodeProject, the most powerful forums in the world and would blow your head clean off, you've got to ask yourself one question, Do I feel lucky? Well do ya punk? Re: Debug Assertion? Aoife3-May-02 5:55 Aoife 3-May-02 5:55  It says that the "Debug Assertion Failed" in file winctrl.cpp at line 547. void CListCtrl::DrawItem(LPDRAWITEMSTRUCT) { ASSERT(FALSE); } This is a MFC\src file. It gives no other reason as to why its happening. Thanks Re: Debug Assertion? Tim Smith3-May-02 6:10 Tim Smith 3-May-02 6:10  Then it looks like your list control is marked as owner drawn but you aren't handling the DrawItem routine to draw it.

Re: Debug Assertion? Aoife3-May-02 6:29 Aoife 3-May-02 6:29  I'm a newbie, so could you please explain how I can fix this? Thanks, Aoife Re: Debug Assertion? Chris Losinger3-May-02 8:50 Chris Losinger 3-May-02 8:50  in the resource editor, open your dialog, double click the listbox then find and un-check the box that says "Owner Drawn" . -c I don't care, and you can't make me. Smaller Animals Software Re: Debug Assertion? Aoife3-May-02 9:02 Aoife 3-May-02 9:02  Worked perfectly! I feel a bit thick that I didn't know that, but I'm so happy that I have finally got my application working that I don't care! Thanks a million Chris. Aoife Getting the data from a CString into an LPVOID data type kyledunn3-May-02 3:23 kyledunn 3-May-02 3:23  If I pass a quoted string variable to the LPVOID argument of a method it accepts it but if I pass a CString to the LPVOID augument I get a compiler error, cannot convert from 'CString' to 'LPVOID'. Can anyone help me with getting the data from a CString into an LPVOID data type? Kyle Re: Getting the data from a CString into an LPVOID data type mystro_AKA_kokie3-May-02 3:53 mystro_AKA_kokie 3-May-02 3:53  Convert first to LPCTSTR then maybe LPSTR then to LPVOID. Re: Getting the data from a CString into an LPVOID data type kyledunn3-May-02 3:56 kyledunn 3-May-02 3:56  Tom Archer shared this answer with me so I wanted to share it with others. Thanks Tom! It's easy. Just call the CString::GetBuffer function. Here's an example where I have a function that takes an LPVOID and another function that calls it twice (once passing a hard coded literal and then with a CString). Note that I'm using VC7. You might need to call GetBuffer(0) in VC6. void CallTest() { Test("abc"); CString str = "def"; Test(str.GetBuffer()); // This is what you need to do in your case. } void Test(LPVOID lp) { AfxMessageBox((const char*)lp); } That should set you up. Cheers, Tom It did! Thanks again Tom. Re: Getting the data from a CString into an LPVOID data type Tom Archer3-May-02 4:17 Tom Archer 3-May-02 4:17  You're welcome, mate. Like I say in the Acknowledgements section of my C# book, being able to share code and help each other on sites like this is one very big reason that programming remains fun after all these years.

Re: Getting the data from a CString into an LPVOID data type Nish Nishant3-May-02 4:24 Nish Nishant 3-May-02 4:24  Hey Tom He said you helped him, but I cant see where It puzzles me no end! Nish Check out last week's Code Project posting stats presentation from :- http://www.busterboy.org/codeproject/ Feel free to make your comments. Re: Getting the data from a CString into an LPVOID data type Tom Archer3-May-02 4:40 Tom Archer 3-May-02 4:40  On another thread he had asked about how to use the registry and I sent him a simple class (CRegistry) I had written for my MFC book (Visual C++.NET Bible). He then asked how to call one of the member functions (WriteString) that takes an LPVOID since the value he wants to pass is in a CString. He must have posted the question here at the same time he emailed me. When I responded, he then updated this thread. Can you tell that I've been writing books for too long? I can't say good morning to someone in less than 50 words any more! Damn editors and their request for more detail!!

I have about 5 chapters at the end on ME, but that's not the focus of the book. Those chapters are more like "if you're interested in this here's some stuff to get you started". Personally, I don't think many people are going to to use ME so I wanted to keep the book focus on MFC. I really hate that publishers are not making this clear in their book titles. I wish the ME books would state in the title (Managed Extensions). As it is now, the readers have no idea just by looking at the title.

Re: Getting the data from a CString into an LPVOID data type Joao Vaz3-May-02 5:39 Joao Vaz 3-May-02 5:39  To be totally honest with you ,IMHO I think that you should need badly the money(the pool isn't in a great shape), personally I don't like the publisher of your forthcoming book , and I hate their Bible Series . Apart from that what will be intended level of audience of the book? Beginner/Intermediate? Now concerning your Inside C#, 2nd, I don't have any doubt that it rocks, although, for money constraints, I will only buy your book on the next 3 months (very optimistic way, by the end of this month) , my company insists in delaying my bonus payment (2 salaries) that I and my fellow colleagues have right Cheers, Joao Vaz Frustrated TCL programmer,good c++ programmer wannabe
