Hello,
I wanted to create 3D vector but i don't know how.
Hope somebuddy can help me.
1D: std::vector<int> v1;
2D: std::vector<std::vector<int>> v2;
Follow up question, how can i copy 3D vector;
Your comments will be a big help.
Thank you.

hi,
std::vector are not equal to graphical vectors. The std::vector is like an Array or list.
You should create your own points.
struct Vector2d
{
int x;
int y;
};
AND
struct Vector3d
{
int x;
int y;
int z;
};
struct Vector3d : public Vector2D
{
int z;
};
codito ergo sum

In my application there are 4 panes created through CSplitterWnd class.on these panes i want a close button like the one provided in panes of outlook express so as to hide nad unhide these panes.i m not getting a way to do this...plz suggest

It's going to involve work for you, but have a look at
CSplitterWnd::DeleteColumn and CSplitterWnd::SplitColumn.
If you have a 2x2 arrangement, then you're not really going to be able to remove just one view.
I'd also be tempted to not use CSplitterWnd. If you search through codeproject, you should be able to find a few articles showing how to do the "new" [*] outlook look.

[*] well, it was new in 2003...

Hi all,
On of my class have a char pointer as follows.
char* message;
In another class I create an instance as pointer type. Then I want to create a string. So I do this.
string str = pInMsg->message;
where pInMsg is the object to the first class.
Is that wrong, I've try to debug and see, make me too wired that. Can you guys help me on that.
I appreciate your help all the time...

It is correct there is one more way to do it is
string str(pInMsg->message);
Yes U Can ...If U Can ,Dream it , U can do it ...ICAN
|
|
|
|
|
Yes, an alternative way.
My question is, only I got the first character. Not all the characters there? 
I appreciate your help all the time...

No it takes the whole string use messagebox to check it.
MessageBox(0,str.c_str(),"1",0);
Yes U Can ...If U Can ,Dream it , U can do it ...ICAN
|
|
|
|
|
Yes it is. That's why I'm worried about it.
Do you have any idea...

str.c_str() gives you a const char *
Given
char * msg;
do std::string m = (std::string) msg;
|
|
|
|
|
But still it gives only the first letter.
I appreciate your help all the time...

That's because you are confused between Unicode and ANSI strings. All of the letters are there, but you are using the Watch window incorrectly. Try appending ,su to the variable.

Errr, is it possible that your problem is upstream?
Are you sure that pInMsg->message is actually a char *? And are you sure it points to more than one char?
try:
char *c = "hello";
std::string str = "boo";
str = "woot";
str = c;
And use the debugger to look at c and str at different stages. If that all works as you'd expect, then you'll just have to have a nap and look again at your code.
Do you have a unicode / not unicode mixup, some parts use TCHAR and you've just not told us it all?

100% sure that is, because I make it....

I didn't think it would take you long to verify it!
I was more interested in the little code I put in the pre section - if that works as expects, then either you have an error in the initial variables going to your real code, or you have the debugger / watch windows set up badly.

I am not sure if this is the exact topic to post here however I thought I'd give it a try.
I have been coding MFC for a few years.
The look and feel of the GUI's (that I create ! ( Dialog based app) seems ( to me ) to look very ordinary .
Sometimes when you demo stuff to customers , part of the deal is to create "Flash" like GUI's that actually have the same functionality of an engineering application ( normally coded using MFC, C++). Customers most often get "wowed" by the new , cool , look and feel instead of the usual gray dialog with buttons and edit boxes.
I am in search of something ( library / component(s)) that can still preserve the ease of coding in MFC/C++ but exposes a whole new world of creating stunning GUI ( rich in color and action ).
I would appreciate if someone could provide ideas for achieving this .
Engineering is the effort !

There are loads of nifty looking controls on a certain website full of code articles... Gradient coloured bubble buttons, all sorts.
I will warn you though - when you venture into Nifty, you usually take a huge detour through Hideous.

You can call CWnd::Invalidate() in your view class to repaint the view.

Hi,
I found an interesting problem with a simple task.
I was adding a context menu to a tree view embedded on a dialog and the dialog is embedded on the main window.
I was using GET_X_LPARAM and GET_Y_LPARAM from windowsx.h
The value returned from GET_X_LPARAM is incorrect (negative) within the WM_NOTIFY section but the GET_Y_LPARAM is ok.
Of course the problem is easily solved by using GetCursorPos but has
(1) Anyone else seen this?
(2) Anyone else can replicate this?
(3) Can someone tell me why this is the case?
Upon looking at the WM_NOTIFY docs is it correct that LPARAM is getting overridden with the
NMHDR structure? So it actually is behaving correctly and it's just by change that the y member is correct and happens not to be overridden?
Regards,
Flip
