I find the easiest way to make such a dialog is to add a hidden 1x1 static control to the dialog where the expansion will take place. In your case, you'd need two. Then when the "shrink" button is clicked, you'd shrink the dialog's left and right edges up to those hidden controls. When the "expand" button is clicked, you'd grow the dialog's left and right edges back to their original position.

hmmm... sounds a very messy way of cutting off the left hand edge.
The object is to show All, Left+Middle or Right+Middle.

Not messy at all. In fact it is very clean and quite common to grow/shrink dialogs in this fashion.

Even though you initially stated, "...how do I cut the dialog's window down so that only the middle 3rd is displayed", what I described will work just fine for all seven possibilities.

I knew I had missed an option. Yes it is All, Left+Middle, Right+Middle or Middle.
Thank you for the suggestion.

Could it be easier to have a series of child dialogs to display/hide part of the main dialog and resize the main dialog accordingly ?

Use the Create() method.

I need to change the up and down arrow of the datetime picker control, I have to put some image there. and also need to some different color when any value is selected in the control.

For this I'd look into WM_CTLCOLOR.

Hi All,
How to sort the items inserted in the tree ctrl?
I have added items in the tree control now i want to sort the items
in alphabetical order.
How to do this?
|
|
|
|
|
use the sorting callback function of the CTreeCtrl ( CTreeCtrl::SortChildrenCB )
for example :
static int CALLBACK MyCompareProc(LPARAM lParam1, LPARAM lParam2, LPARAM )
{
return 0;
}
TVSORTCB tvs;
tvs.lpfnCompare = MyCompareProc; tvs.hParent = TVI_ROOT;
SortChildrenCB(&tvs);

I have located fast libraries for unions of 2 polygons.Now, how does one merge a group of simple polygons.

oh dear,
what i meant was I want a program which takes a group of
input simple polygons and merges them with the 2nd group
of simple polygons.
I have located 2 libraries (both use vatti's) algorithm
for clipping.
My polygons are without hoes,not self intersecting and only graze at edges(if at all).
I want to merge them to get the outer contour of the final merged polygon.
I presume that would be easier to do then the clip in the 2 heavy libraries.

YOu said you located 2 libraries that can "merge" 2 polygons, as i understood, i thought your problem was how you would merge more then two polygons. So actually what you want has nothing to do with the libraries because you don't want to use them but instead you want to do the task without the help of these, right? Well, if you are doing this under windows you could try creating regions from your polygons and merge them (windows can do this for you), how you get the points back from the resultiong region i don't know yet.

yes, i want to merge the regions and just get the outer contour.
As simple as that and I have to use clipper?.(it is in borland delphi/c++)

I doubt Clipper is the only language you could implement this in.

no it is in delphi/c++ and gpc is in c++.I dont a demo program to use
the libraries under vs2010..that is the problem.both use a algorithm
called vattis algorithm in computational Geometry.
in vs2010 /c++(unmanaged) i dont know how to do graphics .

So let me get this straight:
1. one of the libraries you could use is written in C++
2. the second one you could use is written in pure, standard C++
3. you have sources, so not lib files
4. you want to work in VC++ with VS2010, use one of these libraries in it and display graphical representations of your polygons but you don't know how to:
-use any of the libraries in VC++
-do graphics in VC++
If i am correct then i believe you should first learn some basic VC++/Windows programming before getting to the actual implementation of this polygon thing. If one of your libraries is written in standard C++, you probably whould be able to build it with VC++ too.

yes,you got it right.I also know how to do some vc++(the old c++ not the new
one with lambda,..).I know vb.net ok and also c++.
I have asked a friend to help me in command line and probably when i show him my face next we will have a c++ program which
readpolygons,readpoygons,
perform union,
write result polygons
no graphics....so sad...
ps:i have got 1 more library, in c of the previous decades.

Hi All
I am facing very fracturing problem.My application some control move from original position and some control hide.i use Static,Edit Box,List Box,List Control,Picture control and Spin Control.
I use OnEraseBkgnd and OnCtlColor function for background color and control color.Code is here
HBRUSH CTestDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
if((pWnd->GetDlgCtrlID() == IDC_CHECK_REAL) || (pWnd->GetDlgCtrlID() == IDC_STATIC_REAL))
{
hbr = CreateSolidBrush(RGB(250, 252 , 254));
pDC->SetBkColor(RGB(250,252,254));
pDC->SetTextColor(RGB(0,0,0));
pDC->SetBkMode(OPAQUE);
}
if((pWnd->GetDlgCtrlID() == IDC_EDIT_MAXPATH))
{
hbr = CreateSolidBrush(RGB(255, 255 ,255));
pDC->SetBkColor(RGB(255, 255 , 255));
pDC->SetTextColor(RGB(0,0,0));
pDC->SetBkMode(OPAQUE);
}
}
BOOL CtESTDlg::OnEraseBkgnd(CDC* pDC)
{
CRect rect;
GetClientRect(&rect);
pDC->FillSolidRect(rect,RGB(250,252,254));
return TRUE;
}
