BlitzPackage wrote: The standard template library vector (i.e. vector myVector) - can you double subscript it (i.e. myVector[2][3])?
Yes. You just declare it this way:
vector< vector<int> > myVector;
This creates a 2 dimensional array of integers.
BlitzPackage wrote: Do vectors (again from the STL) inherently allocate dynamic memory (the more abundant kind)? In other words, if I use the pushback() method, is the vector allocating that memory dynamically on the heap (or free-store)?
The memory that vector/list/deque/heap/stack/map/set/etc use is on the heap. It allocates and manages it so that you don't have to. Almost all of the STL containers allocate a default size (or a grow-by depending on the type of container) to optimize allocations. They also typically do not resize smaller (so resizing a vector to a smaller size will not free up any memory).

You must learn to look passed the surface to the true meaning of the question, young padawan

Well, Im making a listbox that displays thumbnails of images using a CImageList. The drawing is working fine, but I want the listbox to draw the items in a similar way to the listcontrol. For example:
------------------|^
XXXXX XXXXX |-
XXXXX XXXXX |
XXXXX XXXXX |
img1 img2 |
|
XXXXX XXXXX |
XXXXX XXXXX |
XXXXX XXXXX |
img3 img4 |-
------------------|v
In the ascii above (...), I want to display 2 columns of images (actually, depends on the width of the control) and only the vertical scrollbar. I tried setting the multicolumn property to true on the designer, and it kinda works, but the scroll shown is the horizontal scrollbar, and not the vertical. If I leave the control with multicolumn set to false, there is only one column and a vertical scrollbar (whatever the width of the control, the items wont be calculated to use this space...).
What can I do to accomplish my goal?
Thanks,
Andrés Cartín

u have 4 types of views in a CListView control, Large Icons, small icons, report and list..
if u want that style u should change the style of the listview to Large icons, this can be done at design time by right-clicking the control --> Properties and changing style..
If u want to change the view at runtime u can use CListView::ModifyStyle function, with LVS_ICONS as a parameter.
hope this helps

I know I could have used the listview, but I wont. I need to customly draw a bitmap behind each item (yes, another bitmap apart from the image from the image list). The problem with the listview is that i cant do the drawing of the background image on the OnCustomDrawList. Any help?

You can't using a Modal dialog. If you make your dialog Modeless, you will be able to continue while the dialog is displayed.

You'll need to call CMenu::RemoveMenu and CMenu::InsertMenuItem to physically remove and restore them. There are no hide / show options.

Im not sure its possible or no but if you have a custom menu you can use of drawitem when it want to shows items.

Hi,
Im trying to get this output in the console:
*
**
***
****
*****
******
*******
********
*********
**********
***********
With a genest loop.
How do i get those spaces?
I tried the ascii char '32', but that didn't work either.
Anyone any suggestion?
Thanks in advance!
Edit: its a triangle which is outlined to the right. Its not displayed correctly!
|
|
|
|

strange,
(char)32 or char(32) or you can use (' ') to write a space...
all should work

Hi Mohammed,
Thanks for your reply.
I was kinda wondering how i can increase and decrease the spaces in a geneste for loop.
Do you know how i can do that?
|
|
|
|
|
I dont know what 'genest' mean - not even in the dictionary, so I assume it to mean 'nested loop', if this is true, then here is the code:
<br />
#include <iostream.h><br />
<br />
void main()<br />
{<br />
for (int i=0;i<10;i++)
{<br />
for(int j=0;j<5-i/2;j++)
cout<<' ';<br />
for(int k=0;k<i;k++)
cout<<'*';<br />
for(j=0;j<5-i/2;j++)
cout<<' ';<br />
cout<<endl;<br />
<br />
}<br />
}
hope this helps
Mohammad
