OpenGL comes with the drivers for your graphics card, if the graphics card supports that level of OpenGL. If your graphics card does not support it, level 1.2 is supported through software emulation under Windows XP/Vista and 1.0 under 2000. If you are looking for library support for OpenGL, they are available for each compiler through sites specific for that compiler. Which are you looking for?

VC++ 6.0 should be OpenGL ready, simply install the upgrades:
Service Pack 6.0: http://msdn2.microsoft.com/en-us/vstudio/aa718364.aspx[^]
and if you have nvidia graphics cards: http://developer.nvidia.com/object/sdk-9.html[^]
or if you have ATI: http://ati.amd.com/developer/radeonSDK.html[^]

That should allow appropriate extensions to bring the OpenGL current.

You must add the .lib file to your project: Project/Settings/link, write your name of .lib file to Object/library modules:

the library you're using requires your application to link with multithreaded C run-time libraries. Use the /MT compiler option
(for instance, on Visual Studio 6, choose menu Project->Settings, then on the C/C++ tab, add /MT in the Project Options list).

hope that helps.

SDI as Main View with Zero to Many MDI-like Child Views

C. Peterson31-Mar-07 18:52

31-Mar-07 18:52

Hello All-

I'm working on a SQL database application. The database contains a main table of information, and then each table has another set of data associated with it from another table. What I'd like to do is keep a maximized view of the main table of data open at all times (just like with SDI), and then be able to open up in MDI-like child views of each subset of data associated with an item in the main view.

Another way to describe what I want would be to say I want MDI with the root main frame window also containing a view in it.

Please give me any suggestions you can.

Thank You!

About multi-column listbox

I am doing a multi-column listbox,I set its styles:OwnerDraw-Fixed,Multi-column and "No integal height".Then I add virtual function MeasureItem and add code :
void CColorListBox::MeasureItem(LPMEASUREITEMSTRUCT lpMeasureItemStruct)
{
// TODO: Add your code to determine the size of specified item
CRect rect;
GetWindowRect(&rect);

ScreenToClient(&rect);

lpMeasureItemStruct->itemHeight=rect.Height()/2;
lpMeasureItemStruct->itemWidth=rect.Width()/4;
}

I add a member function to initialize the data and call this function in PreSubclassWindow:
void CColorListBox::InitData()
{
SetItemData(0,RGB(255,0,0));
SetItemData(1,RGB(0,255,0));
SetItemData(2,RGB(0,0,255));
SetItemData(3,RGB(125,0,0));
SetItemData(4,RGB(0,125,0));
SetItemData(5,RGB(0,0,125));
SetItemData(6,RGB(125,125,0));
SetItemData(7,RGB(125,125,125));
}

The last I do DrawItem:
void CColorListBox::DrawItem(LPDRAWITEMSTRUCT lpDrawItemStruct)
{
// TODO: Add your code to draw the specified item
CDC* pDC=CDC::FromHandle(lpDrawItemStruct->hDC);
UINT action=lpDrawItemStruct->itemAction;
UINT state=lpDrawItemStruct->itemState;
CRect rcItem=lpDrawItemStruct->rcItem;

//pDC->SetBkMode(TRANSPARENT);
if( !(state&ODS_SELECTED) )
pDC->FillSolidRect(&rcItem,(COLORREF)lpDrawItemStruct->itemData);
}

Is there something wrong in my operation?I set a breakpoint in MeasureItem and debug the program,but it don't run through the breakpoint?

I appreciate your comments~

CScroll behavior

Hi, I've created a new horz scroll in a CDialog with this:

wnd_hscroll.Create(WS_CHILD | WS_VISIBLE,rct_hscroll ,this,9999);

and set its range with:

wnd_hscroll.SetScrollRange(1,1000,TRUE);

However, the control is not willing to respond to SetScrollPos or sliding the gripper when the app is running.

Any suggestions? Thx.

Live long and prosper

Maintaining .def file is obsolete with currect C++ compilers. Instead you can use __declspec(dllexport).

Editbox in FormView

Hi All,

I have some CEdit's in an CFormView and I can do copy&paste by using the contextual menu but I just cannot do that by using the keyboard combinations Ctrl+C, Ctrl+V and so on. Of course there is no such problem for a CEdit in a CDialog.

I suppose there are some keywords' related messages eaten by CFormView. Any tips on how to solve that? Thanks.
