Hi guys.
I don't know if this is the best place for this post.
If not, please redirect me.
I need a design suggestion.
I have to solve a problem consistent in:
8 balls and 8 boxes. Boxes and balls have diferent sizes.
I have to know if I can put each ball inside one of the boxes.
Evidently the balls must fit inside the boxes.
The problem has solution only when each ball fit inside a box.
I solved this problem using backtracking and works fine.
My question is: there is a fast way to do this than with backtracking?
I need the fastest solution.
Thanks in forwarding.

make a ball class, make a box class. define an overloaded operator for comparing sizes, probably based on the box's height and the ball's diameter. sort both arrays (or vectors). they should be matched up at that point.

Ensure you sort them in the same way, say smallest first. Sorry, could not resist!

I recommend reading this[^] article. It's well written, and includes an easy-to-use communication framework and a full-duplex chat client-server app.

I have a wizard derived from propertysheet. It is a modal dialog which is invoked using DoModal(). Immediately after the wizard is displayed, I want to popup a dialog. But i'm not able to track the exact point after the wizard is shown. In which method of the wizard can i do this ???
Thanx for ur help.

Try doing in the OnInitDialog of your wizard.
|
|
|
|
|
At the end of the sheet's OnInitDialog() method, you'll need to post a user-defined message. In the handler of that message, instantiate the other dialog and call its DoModal() method. You cannot do the latter directly from the sheet's OnInitDialog() method.

If you use a modeless dialog box you can create it and show it within the OnInitDialog method of the wizard.
Basic idea
1) Create dialog
2) Call ShowWindow for the wizard (Ensures that the wizard is shown)
3) Call ShowWindow for the dialog (Shows the modeless dialog)
before returning from the OnInitDialog of the wizard.

Thanx for all ur responses. Its working now !!!
I tried first to post a user defined message from the sheet's InitDialog. But that did not work as expected. Then i tried the same from the InitDialog of the property page. And it worked just as required.
Thanx again.

I have a 4-page document to print out. The first 3-pages are
printed in landscape. This I can do.
The last page needs to be printed in portrait. After the first
3-pages are printed, how can I change the orientation to portrait
without prompting the user to print again and this time select
portrait.
I use this code to switch to landscape:
BOOL CFormOptions::SetLandscape(CPrintInfo* pInfo)
{
tagPDA pPrintDlg;
AfxGetApp()->GetPrinterDeviceDefaults (&pPrintDlg);
pInfo->m_pPD->m_pd.hDevMode = pPrintDlg.hDevMode;
LPDEVMODE devMode = pInfo->m_pPD->GetDevMode();
if (devMode)
{
// devMode->dmPaperSize = DMPAPER_LEGAL;
devMode->dmPaperSize = DMPAPER_LETTER;
devMode->dmOrientation = DMORIENT_LANDSCAPE;
GlobalUnlock(devMode);
}
return DoPreparePrinting(pInfo);
}
and I call a similar function with DMORIENT_PORTRAIT just before
I print the 4th page, but it still prints in LANDSCAPE. Any idea
on how to change the orientation during the print process for just
that last page?
Please, any response any one can give me will be greatly
appreciated.
Sincerely,

From where are you calling this function? Based on the fact that you are returning DoPreparePrinting() I will say you are calling it from OnPreparePrinting(). According to this MSDN page[^] you should be setting the page orientation in OnPrepareDC.
In OnPrepareDC you would update your DEVMODE structure as you have done, then call CDC::ResetDC with the updated DEVMODE to change the orientation.

The secret is that you need to call pDC->ResetDC(&sNewDevModeStruct) after you call pDC->EndPage() for page 3 and prior to calling pDC->StartPage() for page 4.
ResetDC is the magic behind print jobs that have pages that are 1) different orientations 2) sourced from different paper bins 3) different paper sizes.
See MSDN for more info.

is it possible to have a 256 color bitmaps in c++ resource?

Use the import functionality to add them into the resource.

I am using visual C++ .net
I want to try out a simple program by adding a close button on a dialog
what should I type on the
void TryDlg::OnBnClickedButton1()
{
}
Thanks

Take a look at EndDialog.
Or calling OnOk() or OnCancel() works also but DoModal will return IDOK or IDCANCEL then.

|
|
Thanks 
OnCancel works well for the program

maybe u can use inno setup instead.
i had ur problem before.
inno setup is very good except it can not replace files which is in using properly - maybe i lost some features of the setup, u can try it.
u can find downlod link in this forum or by google.
