If you call OpenDocumentFile(NULL) on the document templates for the new document types, this will return CDocument* object to you. You can then cast these pointers to the correct document types and use an overridden operator=(COtherDocType&) function to copy the data across.
Something like this:
void CDoc1Type::CreateCopies()
{
CDocTemplate *pDocTemplate = ?;
CDoc2Type *pDoc2 = static_cast<CDoc2Type>(pDocTemplate->OpenDocumentFile(NULL));
*pDoc2 = this;
...
}
const CDoc2Type& CDoc2Type::Operator=(const CDoc1Type& doc1)
{
}
The coed and the idea is a bit rough. Hopefully it makes sense!

Hi,
This is my first proper MFC app so please bear with me a little, I've got a feeling I have overcomplicated things for myself :/.
I've presently got one document type which maintains a frame grabber, two cameras and their capture (all in one instance) and another type for DIBs. These are intended as the result of any image processing carried out & will have multiple instances.....
As soon as I write this I see the error of my ways  I should just have the main frame own & control the cameras then pass the captured pixel-array to any DIB documents from there.
Shouldn't this simplify maintaining my data? as I'll only ever need the one document type, or is it just as complicated to associate data owned by the main frame with a CView and CMDIChildWnd? (without an accompanying document)
Thanks for the prompt reply btw, if nothing else I'm a little more educated on the workings of the DocManager & DocTemplates

Hi,
When I try to debug a program with microsoft visual studio and use the "step into" command, it gets into library functions (like for example the function "new") and asks me for the path, while I would like of course to debug only the functions I wrote and that are part of the project.
How can I avoid this?
Thank you
Alex

Simple: Don't "Step In". Use "Step Over".
|
|

It's not so simple. If I have something like this:
ptr = new Myclass();
I want to get into the constructor of Myclass and see what happens, I don't want to debug the code of "new". If I use "step over" I don't see what happens inside the constructor.
Anyway, the Borland 4.52 worked differently. By the way, I tried to run it on windows 2000 and it tells me it cannot find the 32 bit compiler (I set the path). Any idea what's wrong?

Put a breakpoint inside the constructor. Duh.

I was about to write "put the breakpoint in the constructor" but you beat me too it. 
Programmers often forget that "contruction" involves more than just calling MyObject::MyObject(). Stepping into new MyObject() may take you to any number of places before you get to the object constructor. If one isn't careful, clean, and clear on this you can introduce bugs through side effects.
Instead of second guessing the runtime, just put break points on the parts you want to inspect.

Hi People!
I’m trying to start an Anti-spam community project. The general purpose of it is to protect and prevent spam from getting in side of users mailboxes; also I want to be able to trace an original spammer, so it can be punished in one way or in another. If things will work out I also would want to change the identification methods for POP/SMTP science I found that most of the email servers have no identification for sending mail (so you can send spam from any user account on the server, and stay undetected)
So if any of you would like to help me please email me or send a post to this treat, thanks.
Also send any ideas if you have!
Alex,

This must be solved, if the server cannot identify itself during the mime transfer then refuse the mime.
Yeah its a good idea....

Is it a server id?
I don’t think so; it is more user identification process for access… If the server is on MS Server OS w/ Exchange than you can just use firewall like ISA to block any one who is not on AD…

As long as there are users of computers, this is an impossible task. Spammers use social engineering to help spread their germs.

If it was as simple as creating a project, the folks at FTC would have already "been there, done that."

Yes, and they can, one thing thay have to think diferently....
If you update the protocols so you can trace the location, than you can go after Spammers, that will reduce spamming ....

While this is being worked on, there is no guarantee that it will be implemented. You cannot foce computers to be upgraded. It's up to the owner/administrator as to what gets updated/patched and what does not.

And If microsoft will release this update?

I spent a week at Microsoft HQ a few years back, talking with some folks in the development and research departments. Out of all that was talked about, what I remember most was what was said about Microsoft's product output. It was said that 90% of the projects presented to Microsoft are terminated very early on (i.e., they only bother creating 10% of all the ideas they receive). Some of them are scraped at the concept stage while others might make it to the early development stage. When asked why, they responded that it costs very little money to determine if a product is worthwhile or not, whereas once a product goes into development, the costs start going up quickly. They would rather spend a few million up front shooting holes in a concept rather than 10 times that later on supporting a product that was not well received. I said all that to say, you'd have to present Microsoft with a very solid case if you wanted them to release it. They already have an initiative in place that pays a reward if certain virus-writers are caught, so the desire to thwart spammers can't be too far off.

Yes, too pruve the MS that the project is woth it you just have to have some expiriense in top level presentations, or wight phone numbers 
My intend to make people afraid of sanding SPAM because FBI can go after them....
Also as I alredy mentioned I can get large companies to cooperate, so I just need people who just want to do it, like for idea and not for money
(Well, yes i can say that because I have a lot of free time and...)

Hi,
I'm new at C++, and am taking over a Visual C++/MFC app. My first assignment involves parsing a data file and creating a graph. Once created i need to interact with the graphdata - for calibration/zoom/etc.
I was wondering where i could find resources on graphing in VC++.
Any suggestions would be greatly appreciated.
Cheers,
Mike

I am using MFC with Visual Studio 2003. Is there a way to retrieve all of the written data off of a CD, and save it as a file? I don't know weather or not copy protection is going to be an issue, and I am assuming that this is not going to be an easy thing to do, so any help at all is appreciated

I am trying to run a Dialog based application on different machines(desktop and a laptop) , both having different display settings . I develop in the Desktop and when i run this app on the laptop I am unable to display all components . How do I make my Dialog adjust to this ? I need to do this both for the main Dialog and all the subcomponents too . Please help
|

If you are comfortable with C++ coding, you could look for the example (CResizingDialog, CResizeableDialog ?) in Dialog controls in CodeProject. There is an example that handles resizing both the "container dialog" and the proper handeling of the controls within the dialog.
Best of luck!
