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 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.

thanks Suman. but i think its only applicable to dialog based apps, im not sure. i dont have a form where i could put/draw/drag the flexgrid control to, since its SDI.

Hi,
How you are creating flxgrid in your application?
Are you creating in runtime?
Depending on that method we will try to get pointer.
Thanks,

Now I've got a problem. I've got an assertion error...
If i'll ignore the assertion message, the app will continue to load showing only two columns and two rows in the flexgrid area.
What i did was i added a class that inherits CMSFlexGrid.
This is the overriden function:
BOOL CGrid::PreCreateWindow(CREATESTRUCT &cs)
{
return CMSFlexGrid::PreCreateWindow(cs);
}
I tried to follow the ways the treeview and listview ctrls are attached to the other panes of my app. Im just confused why flexgrid could not be drawn in the upper right pane.
Thanks,
_chew

Hey, I found a very wonderful editable GridCtrl from codeproject by Chris Maunder. It works fine with my app. I already have a treeview in the left portion, a listview on the bottom right and the grid control on the upper right. during OnCreate, i was able to add column headers to the three panes. still, my old problem exists. i cant obtain a grid control pointer from the treeview side. like when i'll click a tree node, i'll modify the grid control control.
there are many tips and tricks on the net but nothing works for me.
any idea?

Hi,
I think there will be some way to access the control you use..
The CDataGrid[^] is also a ncie control, for which you need to create an instance to access it.
If you still have some problem post it
Thanks,
Suman

Hi !
I was trying to add a amall icon on my application i used WM_SETITEM msg but it is not working.
Win Mob 5.0 Smart Phone SDK & VS 2005 IDE.
For this i have written a code
g_hIcon=LoadIcon(g_hInst,MAKEINTRESOURCE(IDI_ICON1));
SendMessage(hWnd,WM_SETICON,ICON_BIG,(LPARAM)g_hIcon);
|
|
|
|
|
What value does g_hIcon have? What does SendMessage() return?

You need to assign a handler to the BN_CLICKED message. If you have VS6, use ClassWizard (Ctrl+W).

Is that possible? I mean he is talking about CFileDialog...

I assumed he was talking about the button that would construct a CFileDialog object. In any case, a hook can be provided to handle the clicking of the OK or Open button before the Open dialog is dismissed.

Actually I thought about that solution. Probably he can also roll his own class derived by CFileDialog and then override whatever he needs.

There are tons of Web sites that allow this. Have you searched for one?

When you click the Open button on such a dialog, DoModal() will return. You then have access to whatever file was selected by the user.
