You should use a global keyboard hook (see: "Using Hooks") for the purpose.
Are you writing a keylogger?

Thanks for your reply Pallini. I was curious about how keylogger works and while searching, i got a keylogger code in c++. Now i am just trying to edit it, just for a learning purpose.

I see you already found a better way to do what you want, so this is just an "additional footnote" to your original problem: to make your while loop less CPU hungry you can add a Sleep(1) call somewhere inside it, or maybe use SwithToThread[^] (althorough SwitchTothread seems to be much less effective than Sleep), this way the loop yields execution to other threads and does not eat up all the CPU power. I mean something like:
while( 1 )
{
for( int i = 0; i < 256; i++ )
{
GetAsyncKeyState( i );
}
Sleep(1);
}

i have created two modeless dailog and invoking it in InitInstance().
That two dialog is displayed correctly.But what happened is, the second dialog creates icon in Taskbar like main applcation seperatley apart form main application.It has its own close,Move menu option.
How its possible.I posted my code below.
In InitInstance()
pMainFrame->AlarmBanner();
pMainFrame->ToolTab();
void CMainFrame::AlarmBanner()
{
CAlarmBanner *oAbanner;
oAbanner = new CAlarmBanner;
oAbanner->Create(IDD_ALARMBANNER,this);
oAbanner->ShowWindow(SW_NORMAL);
}
void CMainFrame::ToolTab()
{
CToolTab *otoolbar;
otoolbar = new CToolTab;
otoolbar->Create(IDD_TOOLBAR_DIALOG,this);
otoolbar->ShowWindow(SW_NORMAL);
}
BOOL CToolTab::OnInitDialog()
{
CDialog::OnInitDialog();
m_brush.CreateSolidBrush(RGB(173, 216, 230));
SetWindowPos(&CWnd::wndBottom,0,80,45,SystemDM.dmPelsHeight,SWP_SHOWWINDOW);
return TRUE;
}
BOOL CAlarmBanner::OnInitDialog()
{
CDialog::OnInitDialog();
SetWindowPos(&CWnd::wndBottom,0,0, SystemDM.dmPelsWidth, SystemDM.dmPelsHeight/12, SWP_SHOWWINDOW);
return TRUE;
}

The 2nd dialog may have the 'Application Window' property set TRUE. Check the dialog properties and make sure this value is set to FALSE.

Hi,
I edited OnGetMaxMininfo() function to change display size when i maximize the child window like below
int XBorder = GetSystemMetrics(SM_CXMAXIMIZED);
int YBorder = GetSystemMetrics(SM_CYMAXIMIZED);
lpMMI->ptMaxTrackSize.x = XBorder-50;
lpMMI->ptMaxTrackSize.y = YBorder-40;
It comes fine.But what i want is the position of window is from 50,50
Ex:
Left :50,Top:50,Width:XBorder-50,Height:Border-40
How can i get that?
I use
lpMMI->ptMaxPosition.x=50;
lpMMI->ptMaxPosition.y=50;
But no use?
Pls help me.

Im my applcation constanly im placing one dialog at top of the screen.So if i maximize my child windows definetly quater of child frame will get hide behind the dialog.To overcome this problem i planed that when i maximize the child frame,then it maximized to full window but top of the window should below the dialog.
Can u understand my point.

Can't you use the SetWindowPos (and optionally play with the Z-Order) for the one being Maximized? Or does this not fill your requirements?
Regards.

Cannot you just handle WM_SIZE message, sizing your window height to screen height minus the dialog's height (and moving it at the bottom of the dialog) on maximize request?

Yes,
I used that one also.I can get my required window size.But in that maximized window, the title of my child window,system menu,staus bar all are missing.simpla window without caption,without mimnimize,maximize bar is get displayed.When i double click on the bar,then the window comes to previous position with caption and system menu.
I coded like this
void CChildFrame::OnSize(UINT nType, int cx, int cy)
{
CMDIChildWnd::OnSize(nType, cx, cy);
int XBorder = GetSystemMetrics(SM_CXMAXIMIZED);
int YBorder = GetSystemMetrics(SM_CYMAXIMIZED);
switch (nType)
{
case SIZE_MAXIMIZED:
MoveWindow(40,60,XBorder-50,YBorder-40,FALSE);
break;
}
}

Why don't you use the size of the (top) dialog to accordingly resize your frame window?

You said you have a dialog box at the top of the screen. In order to make your frame window appear just below it, you must know (and use) the dialog's height, or am I wrong?

Can someone clarify me the following question - unfortunately I cannot understand it from MSDN docs. There are several messaging libraries in Windows - see http://msdn.microsoft.com/en-us/library/ee663283(VS.85).aspx. The question is: can some of them be used to the following task: to read mails from POP3 mailbox on ANY (not only Microsoft Exchange Server) mail server? For instance, I see on http://msdn.microsoft.com/en-us/library/ms710599(VS.85).aspx description of some IPOP3Transport interface, but with remark 'Do not use'. "http://msdn.microsoft.com/en-us/library/ms709613(VS.85).aspx" says "New applications should not use this set of interfaces and schemas. These interfaces and schemas exist for backward compatibility with legacy applications".
So, this "Windows Mail" is obsolete and should not be used anymore? I am confused. Can someone explain me?

Personally I keep far away from 'MS solutions' for just the reasons you described. What i did (years ago) open a socket and read the mail. The Pop3 protocol is really simple.. Next, you will get your emails as files and you have to get bodies and attachments out. Pop3 and the email format is described and available on internet, open for us all.
Besides of some nasty 'ms-enhancements' in the email adresses, email is pretty standard.
I read the pages you provided: forget it they are just wrappers around the real thing. If you do not want to follow my advice above use the mail-classes of your programming language, they should be reasonably standard.
Send me a private mail if you need more advice...

Hi All,
At one place in my code i need to run IOCTL_DISK_DELETE_DRIVE_LAYOUT, that execute smoothly. This IOCTL code make the disk signature as zero so it can not be initialize.
I need to initialize this disk using code. Is there any API or any function that can initialize the disk?
Please suggest me some way to initialize it using c++ code.
Thanks
MChauhan

Hi,
Is there any MFC method to convert CString object to char array? please tell me how to do this.
Thanks in advance.
Regards,

It is not at all good to convert a CString to char array
unless you are sure that it doesn't contain any UNICODE character.
well there a lot of methods
one of them is
CString csdata = "asdsadasdda";
char* cdata = csdata.GetBuffer();
//When you have done all your needs, use ReleaseBuffer().
csdata.ReleaseBuffer();

Adam Roderick J 09 wrote: char* cdata = csdata.GetBuffer();
Calling GetBuffer is not a good solution in this case, even if you call ReleaseBuffer afterward. There's no need to use GetBuffer because CString already defines casting operators (which returns the same type of what GetBuffer returns, so it depends on the UNICODE settings). Using GetBuffer is very bad practice and should be avoided.
