Re: Changing the toolbar Rand Al'thor4-Dec-02 15:23 Rand Al'thor 4-Dec-02 15:23  Again, no reply.. and again, I've solved the problem ^^ What I do is I create an array of toolbars in my MainFrame, and turn them on and off and redock them as the need arise. Okay.. thanks. Add grid control to a dialog peter ho4-Dec-02 12:35 peter ho 4-Dec-02 12:35  Can anyone provide me some more details of how to add the MFC grid control (wrote by Christ Maunder) to a dialog? I can't make it work using his instruction in the article. Many thanks, peter. Re: Add grid control to a dialog Christian Graus4-Dec-02 15:29 Christian Graus 4-Dec-02 15:29  It's probably appropriate that you ask this in the forum for the article, as Chris is the best person to answer you, and he will get a copy via email if you ask there. It would also help to explain what difficulty you're having. What are the errors you are getting ? What is not working ? etc. Christian No offense, but I don't really want to encourage the creation of another VB developer. - Larry Antram 22 Oct 2002 Hey, at least Logo had, at it's inception, a mechanical turtle.

Using Activex control in dialog is very simple. Would work similar to flexgrid.

NOTE: This is possible only in Windows 95, Windows 98, or Windows Me. Re: Disabled Larsson5-Dec-02 4:03 Larsson 5-Dec-02 4:03  Thank's! Utility to scan for unused headers? Andrew Welch4-Dec-02 12:22 Andrew Welch 4-Dec-02 12:22  Does anyone know of a utility that will scan through your Visual C++ project and list out unused header files, multiply-included headers and the like? We have a big project with some old code that really could use a cleaning like this. Thanks in advance. Andrew CDatabase MFC is the Best4-Dec-02 12:03 MFC is the Best 4-Dec-02 12:03  hello @all, i connected my mfc program and an access database with ODBC. CDatabase db;<br /> db.Open(_T( "MyDatabase" ), FALSE,<br /> FALSE, _T( "ODBC"));<br /> the ODBC driver of my database is called 'MyDatabase'. but when i use this code, the database is not selected. i must select it myself! what must i change to select my odbc driver from the program (i have to do nothing, after i start the program)? thanks mfc creating CPropertyPages mariuszpopiolek4-Dec-02 11:37 mariuszpopiolek 4-Dec-02 11:37  Hi I have two CPropertyPages dialogs, handled by CPropertySheet. I'm executing some code in the second page OnInitDialog handler. This code should be executed during creation of CTreeCtrl located on the second page. After executing this code I receive the data that is needed in first page OnInitDialog handler. Of course I can repeat execution of this code in first page OnInitDialog handler but it would be time consuming (or I can store result of this code so as to use it in second page OnInitDialog, but it means storing it in tree and I want to find easier solution). I have an idea how to solve this problem: second page must be displayed on the beginning (not a problem for me) and after that first page should be activated. The problem is that I cannot fully activate first page. I was able only to change active tab, not the active window inside propertysheet dialog. Thanks in advance for any hints. Mariusz Popiolek passing an iterator Member 1043934-Dec-02 11:34 Member 104393 4-Dec-02 11:34  I am working with some legacy code where a vector<string> t is passed into my function. I created an iterator to read through the vector: vector<string>iterator p I then pass the vector into another function. I want to also pass the iterator so that the new function continues to know where in the vector it is. What is the best way to pass this information? Thanks. Re: passing an iterator Christian Graus4-Dec-02 11:48 Christian Graus 4-Dec-02 11:48  You want to know the index ? Why ? I guess you could pass the index as a number, I just don't get why you would do so.

This is old code but there is too much to rewrite anew. So the first function reads several "lines" (i.e. strings) an then the vector is passed to another function which needs to read off a variable number of "lines" and passes to other functions, etc. Each read takes the next string, thus, I am hopint to pass the iterator to keep track where it is (each function using the iterator to know which index is next to read). I have not used iterators except in very basic uses within one fuction and have not figured out how to pass one. Thanks. Re: passing an iterator Christian Graus4-Dec-02 13:34 Christian Graus 4-Dec-02 13:34  I don't see why it would be hard to pass one - where are you stuck ? Iterators from a vector support random access, so you can both use ++ and -- to step.

Hopefully I did not post this previously as my keyboard seems to be freezing on me. Thanks for your input. Re: passing an iterator Christian Graus4-Dec-02 15:22 Christian Graus 4-Dec-02 15:22  I see - damn typedefs. They should not do any harm, beyond obsfucating your code. I suspect you need to pass them by reference, as the vector is also being passed.

Shared MFC Map Accross Processes orcun colak4-Dec-02 10:55 orcun colak 4-Dec-02 10:55  I would like to share an MFC map object accross 3 processes. I am using CMapStringToString class. Any process can initialize the map at startup and I want the other processes to use a shared copy of this map. How can I do this ? I have no idea so any suggestion is welcome. Thanks in advance Orcun Colak Re: Shared MFC Map Accross Processes Chris Losinger4-Dec-02 11:08 Chris Losinger 4-Dec-02 11:08  i don't think is possible, especially not with MFC. you might be able to do something with shared memory, but it won't be a CMap. -c There's one easy way to prove the effectiveness of 'letting the market decide' when it comes to environmental protection. It's spelt 'S-U-V'. --Holgate, from Plastic Smaller Animals Software Re: Shared MFC Map Accross Processes Navin4-Dec-02 11:21 Navin 4-Dec-02 11:21  It would be quite difficult to do. Probably can't do it at all with a straight up CMap. I think the only way you could share something that dynamic across multiple processes would be to set up a memory-mapped file, and map the new and delete operators for your class to use memory from that file or something. I had a similar problem a while ago, and ended up abandoning my design because of it. Even a broken clock is right twice a day. small design question ... Maximilien4-Dec-02 10:21 Maximilien 4-Dec-02 10:21  Good day! I have a class that holds my data. the part of the data is used to fill a menu ( in a toolbar ), and to fill a listbox ( in a controlbar ). the data is used with the menu command, and when the user d-click in the list. The menu and the listbox are not directly members of the mainframe and are not UI related, and the menu handlers are handled in the CView ( it's multiple view application ); I'm still not sure where to put the data ? as part of the MainFrame since it's from there I'll create the menu and the listbox, and pass a pointer to each ctor ( or some init method ). or as a global singleton ( will pollute the namespace )? Thanks Max. Re: small design question ... ian mariano4-Dec-02 14:26 ian mariano 4-Dec-02 14:26  I suppose that if you're following the traditional MFC Document/View architecture, that your data should reside in your CDocument-derived class. If that's too constrictive, put in your CWinApp-derived class, since it's a global singleton anyway.

How can I make sure that always the last item that was added will be displayed at the bottom of the list box without having to scroll to it ?
