Thank you for the prompt reply.
I understand the basics and have programmed windows such as toolbars (before the common control in Win32), rulers, MDI, etc. Its all the "details" that are so time consuming.
1. Explorer tree view - I'm sure that I am not the first person writing an "explorer" in plain C. Its all the details of determining which drives are available, etc. that take time. However, I don't see any stumbling blocks; just would be nice if I could find complete sample code. The "chicoapp" example on MSDN and the FileTree example on codeproject.com are very useful.
2. Docking Windows - Details include the subtle ways that the mainframe's window borders are drawn/shaded when there is a docked window, the algorithm for outlining where the window can be docked. The slider for resizing the docked window in non-trivial.
3. MDI splitter windows. This also looks very difficult. It appears that you may have to sub-class the drawing of the MDI border and scroll bars in order to display the scrollbar "splitter", etc. Perhaps no one has attempted this in plain C.
Any references to sample code will be appreciated.
Thank you.

I'm looking for code that allows me to download files/pages of the internet. I'm currently using the MFC CInternetSession, etc, but that supports only HTTP/1.0 IIRC.
Because I'm downloading large amounts of small pages, the connection re-use via keep-alive and pipelining should really improve performance.

Hi there!!
I have got quite a big problem and I wonder if you could help me out!!  ! The problem is as follows:
I declared a Class in C++ called Messenger, offering some methods (Which are passed from my GUI). Its purpose
is to handle this methods through to a CORBA Server, which passes it to someone else (should be some kind
of video-conference....).
So the constructor of the class Messenger should include the initialisation of a CORBA-Orb Client. But I absolutely
don't have any idea how this works. I have looked at several examples, but they are all main programs
and no seperated classes like I have.
The code as it is suggested in the main programms is:
main(int argc, char * argv[])
{
try
{
// Initialize the ORB
CORBA::ORB_var orb = CORBA::ORB_init(argc, argv);
// Convert the contents of the file to an object reference.
CORBA::Object_var obj = orb->string_to_object("file://Messenger.ior");
if (CORBA::is_nil(obj.in()))
{
cerr << "Nil Messenger reference" << endl;
throw 0;
}
// Narrow the object reference to a Messenger object reference.
Messenger_var messenger = Messenger::_narrow(obj.in());
if (CORBA::is_nil(messenger.in ()))
{
cerr << "Not a Messenger object reference" << endl;
throw 0;
}
// Create a message and send it to the Messenger.
CORBA::String_var message = CORBA::string_dup("Howdy!");
messenger->send_message ("rick", "Test", message.inout());
// Release resources.
orb->destroy();
}
catch (const CORBA::Exception & ex)
{
cerr << "Caught a CORBA exception: " << ex << endl;
return 1;
}
catch (...)
{
return 1;
}
cout << "Message was sent" << endl;
return 0;
}
exception handling included. I don't see the point of the following code line:
CORBA::ORB_var orb = CORBA::ORB_init(argc, argv);
What are the parameters for, given the init-method??
I hope you understand what I am asking. Sorry for my bad English  I'm going to learn it better (At least I
hope so...)
Thank you very much for your help!

May I recommend you try a corba related newsgroup instead, with emphasis on "newsgroup"?

I want my application to interface to the user's email client application.
I've currently got this working using MAPI, but, of course, not all email clients use MAPI. On my computer it calls MS Outlook, but my real email application is Netscape.
I've tried PJ Naughters' SMTP class but you have to know what the user's SMTP service is called (e.g. smtp.ozemail.com.au, or whatever) and this actually bypasses their email application.
I've also tried his CMC class, but CMC seems to be an ancient concept that has not continued existence.
My requirement is simply to call the user's email application, supplying the "to" address and an attachment.
Does anyone have any idea how to do this on Windows?
(It's trivial on UNIX).

To get you started, you can call ShellExecute() on "mailto:person@whatever.com?Subject=Subject here" to open the mail client with a new message.

Thanks for the suggestion Mike, but there's no way to attach a file with this "mailto" mechanism.

Yep, sure is. Just use mailto:address@domain.com?attach="your attachment.ext"
Hope that helps,
Andrew.

Is there any way of specifying the attachment *and* a subject?
Thanks for this excellent tip.
|
|
|
|

I tried this using outlook and it worked for setting both subject and attachment.
CString strTemp = _T("C:\\test.txt");
strTemp.Format (_T("mailto:xxx@yyy.com?Subject=My subject\"%s\""),strFilePath);
ShellExecute (NULL, //Parent window
_T("open"), //verb
strTemp,
NULL,//File
NULL,//Parameters
SW_SHOW);

Hi Andrew,
With Outlook Express 5 I can't get ?attach to do anything - it seems to be ignored. ?subject works fine though.
Do you (or anyone) have any suggestion? I remember trying this a couple of years ago and getting nowhere. It is much better than using MAPI, but I have to be able to specify the attachment.
Cheers, Simon

Hi Andrew,
Thanks for the response, and I'm sorry that I haven't replied sooner.....been busy fighting other fires.
Unfortunately, the attach parameter doesn't seem to work at all.
I've tried with Outlook Express 5 and Netscape Communicator as email clients. It doesn't work with either.
I can get subject and body parameters to work, but the attach is just ignored.
Also, I haven't found any information anywhere on the net that documents this facility.
RFCs 1738 and 2368 don't mention "attach", though RFC 2368 allows for the possibility of it.
So, it looks like I'm going to have to "do it myself" somehow.

Some image viewer application programs, for example, Adobe Photoshop(http://www.adobe.com/) or
SolidWorks(http://www.solidworks.com) set thumbnail image of a file to its file icon in Explorer so that
the users can know the content of the image file without opening it.
(I do not imply "Thumbnail View" when Explorer is at "Web Page" mode, but customized icon only for a file
in place of the application's general file icon.)
I want to do same thing above in my application program. If anybody know how to set thumbnail image
(custamized icon) to a file icon in place of the application's general file icon in Explorer, please tell me.

Thank you for your reply. I think that's what I want to know.
I'm going to see the recommended article in detail.

At first, I greatly appreciate your advice. I can understand how to customize the icons
and icon handler architecture.
Well, I have another question:
- - -
How to retrieve a handle to an icon from the specified file as we can do same thing from
DLL or EXE using 'ExtractIcon' function ?
- - -
I'm sorry to trouble you so often. If you can find time for me, please tell me the solution
about this.

Sorry, I don't quite understand what you're asking. Is ExtractIcon not working?

Oh, I apologize to you if my description was not enough.
At first, Visual C++ 6.0 Help reads that ExtractIcon function retrieves a handle to an icon from
the specified executable file, dynamic-link library (DLL), or icon file. Then, I actually try to use
ExtractIcon function for text file (.txt), but ExtractIcon would not work as Help reads.
If there is a way to retrieve a handle to an icon from '.EXE', '.DLL', or '.ICO', I think there is also
a way to do same from '.TXT'.
Should I use IExtractIcon interface like Explorer? If so, I want to know how to use IExtractIcon
interface ( I understand how to implement IExtractIcon interface for Explorer to use thanks to
you ). Or, If there is more easier way like using ExtractIcon for '.EXE', '.DLL', or '.ICO, please instruct
me.

Ah ok, you want to get the icon that's used for TXT files, right? The way to do that is with SHGetFileInfo(), such as:
SHFILEINFO info;
SHGetFileInfo ( _T("foo.txt"), FILE_ATTRIBUTE_NORMAL, &info, sizeof(SHFILEINFO),
SHGFI_ICON | SHGFI_USEFILEATTRIBUTES );
After that, info.hIcon is the icon. Add SHGFI_SMALLICON to the flags if you want the small (16x16) icon.

Yes, that's what I want to do. Thank you very much.
Also, I'm coming to understand where I should refer in VC++ Help thanks to
your advices, so I wish to express my appreciation to you again.
Thanks a lot.
Sincerely yours

Hi,
I faced some problem when develop a small Internet reliant application, could you help me to solve them ?
How to use get/put_onsubmit method of interface IHTMLFormElement when hosting a WebBrowser control in an
application ?
How to hosting more than one WebBrowser control in an application, which use same session on the server ? Once the
session is authenticated by first created control, other controls can enlist in the same session.
Thank you.

Does anybody know how to display a bitmap from memory DC into the SS_BITMAP-style static control ? Where shuld be this memory DC derived from ?
Thanks for suggestion.
Petr Pivonka

Your memory DC would be a CDC and as a bitmap static gets set with a bitmap, I'd suggest using GetCurrentBitmap to get the bitmap out of the DC and pass into the static.
