Posting WM_CLOSE message to the main thread using PostThreadMessage doesn't close your application also. You have to post WM_CLOSE message to all windows on the main thread, as vikrams said. Here's the code how to do this :

// define callback function like below
BOOL CALLBACK EnumThreadWndProc(HWND hwnd, LPARAM lParam)
{
::PostMessage(hwnd,WM_CLOSE,0,0);
return TRUE;
}
// call EnumThreadWindows instead of PostThreadMessage
EnumThreadWindows(rp[option-1].dwThreadId,EnumThreadWndProc,0);

Very Important!!!! Don't use WM_QUIT message to kill other processes. Instead of WM_QUIT use WM_CLOSE. If you send WM_QUIT the application will not clean up resources and you will have memory leaks. Regards, Andrzej Markowski

Your program has to save the ThreadId for each new created process. Later the ThreadId is passed as the parameter to the PostThreadMessage function which is called to close the program the user opened. The modified example saves this information in the rp array of RUNNING_PROCESS_INFO structures. The nRPCounter specifies a number of currently running processes and also is the next avaliable index in the rp table. When the process is created a space for the RUNNING_PROCESS_INFO structure is allocated at the and of the array and the nRPCounter is incremented. When the user closes the program the counter is decremented and the structures in the array located below deleted item are moved one item up.

#include stdio.h
#include process.h
#include iostream.h
#include time.h
#include windows.h

typedef struct
{
DWORD dwThreadId;
BYTE bProcessType; // 1 - FreeCell 2 - MineSweeper 3 - Paint

int nRPCounter = 0; // running processes counter

You should declare the arrays (si and pi) as global variables. Also you can't call the DisplayMenu from within the process function (recursion). Here's an example how to fix these problems:

STARTUPINFO si[3];
PROCESS_INFORMATION pi[3];

int DisplayMenu();
void process(int option);

void main()
{
ZeroMemory( &si[0], sizeof(si[0]) );
si[0].cb = sizeof(si[0]);
ZeroMemory( &pi[0], sizeof(pi[0]) );

ZeroMemory( &si[1], sizeof(si[1]) );
si[1].cb = sizeof(si[1]);
ZeroMemory( &pi[1], sizeof(pi[1]) );

ZeroMemory( &si[2], sizeof(si[2]) );
si[2].cb = sizeof(si[2]);
ZeroMemory( &pi[2], sizeof(pi[2]) );

while(DisplayMenu()!=4)
return;
}

int DisplayMenu()
{
int option;
system("cls");
cout << "\n\n\n";
cout << "\n\t*********************************";
cout << "\n\t* *";
cout << "\n\t* MENU *";
cout << "\n\t* *";
cout << "\n\t* 1. FreeCell *";
cout << "\n\t* 2. MineSweeper *";
cout << "\n\t* 3. Paint *";
cout << "\n\t* 4. Quit *";
cout << "\n\t* *";
cout << "\n\t*********************************";

cout << "\n\nPlease type your choice "
<< "and press the return key : ";

cin >> option;
process(option);
return option;
}

void process(int option)
{
switch (option)
{
case 1 : if(pi[0].hProcess==NULL)CreateProcess( NULL,
"FreeCell.exe",
NULL,

// CloseHandle( pi[3].hProcess );
// CloseHandle( pi[3].hThread );

break;

default : printf("\a\aOption Not Available\n");
break;
}

return;
}

You should use the DIB (device independant bitmap) and the StretchDIBits function to print your bitmap. More info here: http://www.codeguru.com/forum/showthread.php?t=234177 ____________________ A.M.

If you use the DDB (device dependant bitmap) and the BitBlt function to print your bitmap you will find the answer here: http://www.codeguru.com/forum/showthread.php?t=234177 ____________________ A.M.

A few sugestions: #1 Make shure you call SetCurSel() in OnInitDialog of the property page, otherwise the string will be empty. #2 Make shure if id of your combobox is equal IDC_COMBO1 and is not assigned to another control #3 If the combobox is placed on the property page, use this: pPropertySheet->GetPage(PageNo)->GetDlgWindowText(IDC_COMBO1,s). ***** A.M.

Do the following steps:

CBitmap bmpYourBitmap; // your bitmap
CDC *pDC; // device context for painting
//
// 1. Create a memory device context:
CDC memDC;
memDC.CreateCompatibleDC(pDC);
//
// 2. Select your bitmap into memDC:
CBitmap *pOldBmp = memDc.SelectObject(&bmpYourBitmap);
//
// 3. Get the size of bmpYourBitmap:
BITMAP bm;
bmpYouBitmap.GetBitmap(&bm);
//
// 4. Paint the bitmap:
pDC->BitBlt(0,0,bm.bmWidth,bm.bmHeight,&memDC,0,0,SRCCOPY);
memDc.SelectObject(pOldBmp);

I can't find any relation between the base class virtual/non virtual destructor and delete operator. Could you explain your message?
