The difference is like the difference between englisch and french, with all the literature written in it. What do you want to do with it? A language, or, better, the technologie you use should help you to solve your problems. 1) Your design shoule be "as independent as possible from the language" 2) Define what you want to do, what are the interactions. Maybe use uml for make it clear. Usecases are good to start. 3) Make a decision. Look what woule be the best technologie, wath the customer excepts, and what are the scills of you employees? MFC is a c++ library used by microsoft. ActiveX, OLE, COM, DCOM, ADO are language-independent communication-layers. DAO normally means data-access-object. This is more a design-pattern. Good luck, Hardy.

With closed I mean closed-source. I don't have the source. The window itselve is open, of course. Sorry, it was not clear.

If you have a handle to the (edit) control, you can use GetWindowText() to get its contents.

I think its not so simple. The Application ( A1 ) to control the Hardware is ready and closed. I am writing a new App ( A2 ) , in mfc, to do some extra-work. Now I want to access A1`s main window. I want to write to it and read from it from within A2. Thanks, Hardy.

In VC6, go to project ment, the to properties ( ok, I have a german version, so I don't know the exact name. ) There you find on the left side your build-targest, and on the right side a tab-control. In the tab, ther is a page called "linker". Go to it, There is a edit "Objects, libs". Add your library there. Then, click on category and point to input. There add your additional library-path. That's all. Good luck!

First, pos = AfxGetApp()->GetFirstDocTemplatePosition(); ASSERT(pos); pTemplate=AfxGetApp()->GetNextDocTemplate(pos); POSITION docpos=pTemplate->GetFirstDocPosition( ); get the first DocTemplate. Then you can enumerate your views. CDocument *pDocument=NULL; while (docpos) { pDocument = pTemplate->GetNextDoc(docpos); ASSERT(pDocument); POSITION viewpos = pDocument->GetFirstViewPosition(); while (viewpos != NULL) { ... } } Hope this helps, Hardy.

Is there a lib included in the package you downloaded? If yes, you have not added it to your project. ( project, options, linker ) If you have sourcecode, add the sourcefiles ( the .c or .cpp ) to you project. Your trace shows many warnings because you initialise some variables you never use and then the constructor from MysqlConnection is not found.

Hi all, I want to "control" an application with a second one. The app it there to control a Hardware and I don't have the code:(. It is command-based: I can write a command in a CEdit-like window, and the response is displayed in the same window. ( a Hexdump, maybe ) Is it possible to grap the contents of this window and to write ( from my own app ) into it? Somethink like enumerateWindow and then access over the clipboard? :confused: Thanks , Hardy.

Hi Folks, I am searching a listbox similar to the "favorits" list in IE6. A List with buttons or hyperlinks whitch I can dynamically add and remove. I need it for a MFC-App. Sorry, don`t have time to write it myselfe... Anybody knows something?? Thanks, Hardy.

Remove the Classes. The Classes are not the control itselfe. They just interface it. Hardy

You have to return a value in the bool-Method. return true; Hardy.

Have you implemented the operator? logical operator ! (logical x) { ... return ... ; } If not, you will have of course a linker error! Hardy

And, does it work? Looks good so far. You may also want to use memset. memset( board, 0, sizeof( board ) ); Hardy.

You can also try to use thread-save lists. I think there are some at www.stlport.org. Hardy.

Now I understand. You want to enumerate the com-ports of a machine? Look here: http://www.codeproject.com/system/enumports.asp[^] Hardy.

I would recommand you to use a real database server, Firebird for example. www.ibphoenix.com Do you want to program odbc lowlevel? If not, take a look at the database-Classes here in codeproject. http://www.codeproject.com/database/#ODBC[^] There are some examples. Hardy.

Database design: http://www.edm2.com/0612/msql7.html Accessing with VC++: www.codeproject.com/database/odbcrecordset.asp And for a Database look at www.ibphoenix.com and get Firebird.

The CSerial- class has a "Open" and "Close" Method and it can be configured. So call open from your menu's message-handler to open the comport:), but take care that you write the configuration before. To close it, just call the close-Method. I think there is a example-App with CSerial. Hardy.

Language -- for what?? Programming language - c++, Language for user interface ?? Whatever you like. Are you a programmer?

And where do you need help? In designing the database, in asking the database ( sql ) or in reading the answer ( c++ ) Hardy.

What do you mean with variables?? Hardy.
