Re: Header file to Library ... Steen Krogsgaard13-Sep-01 3:04 Steen Krogsgaard 13-Sep-01 3:04  You still need to include the .h file in your project. Think of it this way: To use a class you need two things: a declaration and an implementation. The declaration usually goes into the .h file, and the implementation usually goes into the .cpp file. When the compiler compiles the source code where you use your class it has to know how the class is *declared* but not how it is *implemeneted*. When all .cpp files of your project has been compiled, the linker makes sure that all the references to your class is resolved - i.e. all the pointers to your class' member variables and methods have valid values. To do this the linker needs to know the addresses of the methods, and this is dependent on the implementation. So, the linker has to know the implementation of your class. If the class is implemented in a .cpp file included in your project then the linking information is available already. However, if your class is implemented in a DLL the linker needs to get this info from somewhere - and this somewhere is your .lib file. The .lib file contains a list of all the (exported) classes and their methods, along with the relative addresses of these methods. Now the linker can do its job and all's well. So, the compiler needs to know the declaration - you have to include the .h file. The linker needs to know the implementation - you have to put the .lib file in the lib path. Cheers Steen.

Please explain, How can i import my DLL to my project ... and how can i use of that ? i must define .h to my project again ? My month article: Game programming by DirectX by Lan Mader.

Steen Krogsgaard13-Sep-01 4:12 Steen Krogsgaard 13-Sep-01 4:12  Here's the steps: You already have a DLL that was made from a MFC extension DLL project. In this DLL you have some classes that are exported by means of the AFX_EXT_CLASS macro. These classes are declared in a number of .h files. By compiling this project you have the DLL file and the .lib file. To use this DLL in another project you would: a) include the header(s) declaring the exported classes in the relevant source files in your app project. This is the very same .h files you used when you compiled the DLL project. b) put the path to the .lib file into the project settings: Project->Settings->Link tab->General category->Object/library modules compile and enjoy Cheers Steen.

Automatic Radio Buttons Derek Lakin12-Sep-01 22:20 Derek Lakin 12-Sep-01 22:20  I'm trying to fix the bug in my CButtonSSL class regarding radio buttons. I'm getting there (at least it doesn't crash any more!), but I'm still having a few problems. The Platform SDK: Windows User Interface documentation for Radio Buttons states: When the user selects either state [checked or cleared], the radio button receives the keyboard focus. The system sends the button's parent window a WM_COMMAND message containing the BN_CLICKED notification code. The parent window doesn't acknowledge this message if it comes from an automatic radio button because the system automatically sets the check state for that style." ... "When the user selects an automatic radio button, the system automatically sets the check state of all other buttons within the same group to be cleared." My question is how? Where does the system handle this? If I have a group of radio buttons I can see the sending of the BM_SETCHECK and BM_GETCHECK messages to the radio buttons but when my button gets clicked there is no BM_SETCHECK message sent even though it has the BS_AUTORADIOBUTTON style set. Derek Lakin. Salamander Software Ltd. Re: Automatic Radio Buttons Tomasz Sowinski13-Sep-01 1:51 Tomasz Sowinski 13-Sep-01 1:51  Where does the system handle this? Spy++ shows that it's a WM_LBUTTONUP which triggers the sequence of BM_GETCHECK and BM_SETCHECK messages. Tomasz Sowinski -- http://www.shooltz.com Re: Automatic Radio Buttons Derek Lakin13-Sep-01 2:02 Derek Lakin 13-Sep-01 2:02  I couldn't get a handle on where this was happening or why my buttons weren't getting BM_SETCHECK messages so I've handled it all in the OnClick event handler. It traverses through the controls in the same group sending BM_SETCHECK to each in turn. Does this seem like a sensible solution? It appears to work for radio groups of mixed standard and custom radio buttons and groups of all custom radio buttons. Derek Lakin. Salamander Software Ltd. Re: Automatic Radio Buttons Tomasz Sowinski13-Sep-01 2:17 Tomasz Sowinski 13-Sep-01 2:17  If it works, it is a sensible solution. Technically, the only difference between your code and Windows is that you're setting buttons states in response to (reflected) BN_CLICKED. With autoradiobuttons, BN_CLICKED notification is sent to parent dialog during WM_LBUTTONUP processing, after series of BM_SETCHECKs.

Re: help with MSXML Michael Dunn12-Sep-01 22:30 Michael Dunn 12-Sep-01 22:30  LNK2001 usually is fixed by linking with the right .LIB file. If you do a text search of your LIB directory, you'll find IXMLDOMDocument in uuid.lib (but you need the Platform SDK installed so you have the latest LIBs). CLSID_DOMDocument2 is in msxml2.lib in the prerelease directory. --Mike-- http://home.inreach.com/mdunn/ Ford: How would you react if I said that I'm not from Guildford after all, but from a small planet somewhere in the vicinity of Betelguese?

Re: help with MSXML 13-Sep-01 1:49 13-Sep-01 1:49  Thanks! I'd actually found by myself by playing with Project->Settings, the problem I have now is that I should'nt have done it because now I get thousands of all kind of errors!!! Do you know how to undo the disaster I've provoked??? Re: help with MSXML Erik Thompson13-Sep-01 8:36 Erik Thompson 13-Sep-01 8:36  It may be simpler to do a #import of the dll to get the typlib and header files needed for the namespace. This is normally how I do it when using MSXML in any of my projects. I don't have a sample of it where I currently am. I'll look for it when I return home. Cheers, -Erik ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ My thoughts are my own and reflect on no other.

I'd like the code in VB or VC bt Vb is preffered. I need it to be downloded from Internet (i.e. my website) and I'd appreciate the message box like Yahoo and Google Does like "Always trust content from My Website" Please let me know what things do you require. I'll need the full source code and I'll need a manual of the updations to be done. I want it to be fully customizeable. That means I should be able to add new links, creat new menus and evrything that is possible...!!! We can then talk later to discuss the other matters. Your name will be listed in the about box. CAn you please show me an online demo of your work..??? Please reply asap...!!! Sincerely, Ajay Re: I need a custom IE Toolbar Jonathon Lockett12-Sep-01 22:22 Jonathon Lockett 12-Sep-01 22:22  Bloody hell, you don't ask much, do you ? The information to do what you want is all on this site. I don't know if it can be done in VB, but it can certainly be done in a *real* programing language like VC++. I'd suggest that the first step in finding a willing slave if you're unwilling to learn to do it yourself despite the excellent tutorials on the site is to put a name to your posts.
