You know, if Microsoft keeps hiding stuff the way they do, someone is going to need to put together some type of repository where we can get to it all. Sort of a "developer network" type of thing.

Great idea David! But shouldn't you have posted it in the Suggestions forum?

void Serialize(CArchive &ar)
{
if (ar.IsStoring()) {
} else {
}
}
Any easy way to do this? 
|
|
|
|

Short answer: Depends.
The CArchive represents only one file - it doesn't even have to represent a file, it could be a stream, etc.
Do you have one document, but the data in it should be saved into multiple files? Then don;t use the CDocument::Serialize method (I never do!), override the CDocument::OnOpenDocument method instead (and its corresponding save method).
You can then save / load however you like!
"Easy" will depend on just what you want to achieve.

If you really need to store multiple file into yor unique one, you have to copy every file content (possibly each one prefixed by its length).
You may wrap this behaviour into a serializable class (you may call it CFile, oops, no, wait a moment...).

I'm getting a strange error...
if I write:
if (uType == ANNEAL)
{
CAnneal * pOrigAnn = dynamic_cast<CAnneal *> (pOrigItem) ;
if(pOrigAnn != NULL)
{
CAnneal * pAnneal = new CAnneal();
}
...
Everything's fine. But, if I want to use a case instead of an if
switch (uType)
{
case ANNEAL:
CAnneal * pOrigAnn = dynamic_cast<CAnneal *> (pOrigItem) ;
if(pOrigAnn != NULL)
{
CAnneal * pAnneal = new CAnneal();
}
break;
case WHATEVER:
...
I get an error that says "initialization of 'pOrigAnn' is skipped by 'default' label" ... "See declaration of pOrigAnn"

Beacause you've not included your code inside a block and pOriginAnn is the whole switch block (while its assignment happens only in ANNEAL case.
You may change it to
switch (uType)
{
case ANNEAL:
{
CAnneal * pOrigAnn = dynamic_cast<CAnneal *> (pOrigItem) ;
if(pOrigAnn != NULL)
{
CAnneal * pAnneal = new CAnneal();
}
}
break;
case WHATEVER:
...

Hi,
So you got the problem..

Hi,
Is there any other access of "pOrigAnn" outside of "case ANNEAL" like:

switch (uType){
case ANNEAL:
CAnneal * pOrigAnn = dynamic_cast<CAnneal *> (pOrigItem);
if(pOrigAnn != NULL){
CAnneal * pAnneal = new CAnneal();
}
break;
case WHATEVER:...
...
break;
default:
...
}
//access pOrigAnn
or somewhere else?
Thanks,
Suman

Hello everyone,
A little confused after reading C++ FAQ, "Why doesn't delete zero out its operand?"
http://www.research.att.com/~bs/bs_faq2.html#delete-zero
I think the reason why delete can not zero out its operand is because delete can be operate on rvalue, like
delete f(x);
And we can not assign zero to the rvalue (i.e. delete's operand). My understanding correct?
thanks in advance,
George

Yes, Bjarne states that clearly.

Hi,
I am looking for algorithm which will find the given point is inside of a given polygon(a triangle) or not.
Which will work for coordinate in -ve and +ve direction.
Best Regards,
Suman

If you can walk over the lines polygon you should find the point always on the same side either left or right.
Otherwise check out this page[^]

You don't like PtInRegion and CreatePolyRegion functions, do you?

Hi,
Thanks for help..
How to create the region when the points are not in order and we need to fill the complete region by connecting outermost points using CreatePolyRegion()?
Thanks,
Suman

Aren't you able to order the points? Is the polygon convex?
Try also the Graphics forum [^].

The polygon can be of any type.
The points may not be in order most of the time.
I will post in Graphics section
Thanks for help!!

You need Convex Hull of points to find a polygon including all points.

Hi,
Thanks for the help.
Is there function to get convex hull of points from set of polygon points which is not in order.
Thanks,

hi guys. just started with visual c++ mfc. im currently making an SDI app with two splitters. 1 vertical and 1 horizontal. i used the SDI (windows explorer) wizard but added one horizontal splitter. leftview is a treeview control, lower right is listview control. for the upper right, the msflexgrid control. i used the "add to project-components and controls-registered activex comps" for the flexgrid. how can i obtain a pointer to my flexgrid (for manipulation)? like when i'll click on a tree node, i want to do something with my flexgrid.
any help will much be appreciated. and sorry for my english...thanks.
