This is quite a complex project and the above comment suggests you are just starting out. Do you know how to create a simple Windows program with menu, toolbar etc?

If you want to block the Key board and mouse input reaching your application then use BlockInput API [^]

Yess 100% possible 
you need to include these files is needed
#include <afx.h>
#include <winable.h>
But i cannot understand the purpose of doing so.

i wrote like this
#include <iostream>
#include <windows.h>
#include <winable.h>
using namespace std;
int main()
{
BlockInput(true);
Sleep(5000);
return 0;
}
its working fine for 5000ms only. but my motto is to unlock the system while i press esc key. how to do this? plz help.

BlockInput itself is done to block any keyboard event till some action is over. So how can it be possible to click of ESC to work?

I new at C++ but i can't seem to figure out whats wrong with my code.
//Specification: Display a menu
//Find Errors in this program
#include <<iostream>>
int main ()
{
cout << "Choose From Martha's Menu:/n";
cout << "1 - Dinner" cout << endln << 2 - "Lunch: ";
cout << endln << "3 - Breakfast";
cout << "Enter a number:"
int Choice = 0;
cin >> choice;
cout << "\n You Choose " << choice;
return 0;
}

PLease try to learn the usage of syntax of C++. The syntax used in your code is wrong.
Syntax related error can be cleared only working with it.
Which you have do
I prefer you to study with Learning C++ A hands On Approach by Eric Nagler. [^]
Well your case firstly #include <iostream>
you didn't specified the namespace.
Either use
using namespace std
std::cout
and next is related endln, actually that is endl.
Please learn using the text, it is better for you.

I have calling Initialize function with these parameters
Initialize(this->GetDC(),200,200);
Unhandled exception occurred at: m_pBitmap->CreateCompatibleBitmap(pInputDC,width,height);
void Initialize(CDC* pInputDC,int width, int height)
{
CDC *m_pDC;
CBitmap* m_pBitmap;
m_pDC->CreateCompatibleDC(pInputDC);
m_pBitmap->CreateCompatibleBitmap(pInputDC, width, height);
m_pDC->SelectObject(m_pBitmap);
m_pDC->Rectangle(0,0,width,height);
}
This is shown in call stack when exception occurred:
mfc80ud.dll!CGdiObject::Attach(void * hObject=0xb90510f0) Line 1157 + 0x3 bytes
mfc80ud.dll!CBitmap::CreateCompatibleBitmap(CDC * pDC=0x004bf954, int nWidth=336, int nHeight=189) Line 251 + 0x25 bytes
AxGraph.ocx!CGraphCtrl::Initialize(CDC * pInputDC=0x004bf954, int width=336, int height=189) Line 27
I could not understand why is this happening. Help to resolve the issue.

Did you allocated memory for of CBitmap* and CDC* using new?

Hi,
Usually I instantiate my CDialog based classes in my view class. Then CMyView class typically creates a modal dialog and then launches a function on OK from which I can easily access the dialog variables.
Unfortunately, the wizard implementation of CPropertySheet has no default constructor. So you are forced to construct it in the view function that is called from a toolbar menu or similar. Then the property page variables have to be duplicated in CMyView class and copied. I have 2 books that show it done this way.
Here is the wizard CPropertySheet constructor code-
CMyDlg::CMyDlg(UINT nIDCaption, CWnd* pParentWnd, UINT iSelectPage)
:CPropertySheet(nIDCaption, pParentWnd, iSelectPage)
{
}
CMyDlg::CMyDlg(LPCTSTR pszCaption, CWnd* pParentWnd, UINT iSelectPage)
:CPropertySheet(pszCaption, pParentWnd, iSelectPage)
{
And the constructor in CMyView looks like -
CMyDlg CMyDlg(_T(" "),this);
or
CMyDlg CMyDlg(_T(" "));
if (CMyDlg.DoModal() == IDOK){
(both verified to work)
If I now add the appropriate default constructors to the PropertySheet .h and .cpp files -
CMyDlg();
CMyDlg::CMyDlg():CPropertySheet()
{
}
I then instantiate CMyDlg in the view class instead of constructing it in the menu function.
I don't get any compile errors but the dialog (property page) does not display when DoModal is called even though there is no run time error.
I suppose I should admit defeat and call the constructor as designed.

HI all,
I have written some code about changing Modification Time and Access Time in File.
My code tries to change both time every one minute.
But, sometimes, Modification Time is not changed by _utime() with 'NO ERROR' after running few hours. (but, Access time is changed.)
Below is the code used to changed times.
if anyone know why the problem is appeared and how i can solve,
Please, let me know
Thanks.
+++++++++++++++++++++++++++++++++++++++++++++++
BOOL SetModificationTime( time_t t )
{
struct _utimbuf uti;
uti.actime = t;
uti.modtime = t;
if (_utime(szPath, &uti))
{
OutputDebugString("Error : Faid to change time");
return FALSE;
}
}

My Program's minimum supported client is Windows 2000. T.T
is There any other way to solve?

Have you tried SetFileTime()?

I wrote the below code in an attempt to set a 500ms timer. CreateWaitableTimer returns a valid handle and SetWaitableTimer() returns 1 indicating success, however TimerAPCProc() never gets called. Can anybody see what's wrong with this code?
VOID CALLBACK __stdcall TimerAPCProc(LPVOID lpArgToCompletionRoutine, <br />
DWORD dwTimerLowValue, DWORD dwTimerHighValue)<br />
{<br />
<br />
}<br />
<br />
void SetTimer()<br />
{<br />
m_hTimer = CreateWaitableTimer(NULL, false, NULL);<br />
LARGE_INTEGER liInterval;<br />
liInterval.QuadPart = -500000000;<br />
int dSuccess = SetWaitableTimer(m_hTimer, &liInterval, 0, TimerAPCProc, NULL, false);<br />
}
Thanks for any help you can offer.

Thanks for the reply and information. The timer is being created in the main thread so it's definitely not a problem of it exiting too soon. I also tried setting the time to -1 just to try and get it to call the TimerAPCProc but still it wouldn't.
I solved the problem by switching to SetTimer(). For some reason I thought SetTimer() worked in seconds rather than milliseconds and that's the only reason I was using SetWaitableTimer(). I was looking for an alternative time and noticed SetTimer() took a value in milliseconds so it was fine for what I needed.
I still don't understand why SetWaitableTimer() wouldn't work but it doesn't really matter now.
