AFAIK, you will get one event when a key is pressed and another event when the key is released.
Get those events and keep track of what key(s) are currently pressed.

You may poll what keys are pressed by calling ::GetAsyncKeyState( <virtual key code> ).
For virtual key codes you can use VK_LEFT, VK_RIGHT, VK_UP and VK_DOWN for the arrow keys.

GetAsyncKeyState(); seems to work perfectly so far!

thanks all of you!!!

Just a quick question:
i can do int data = 0xF; but how do i do the same thing with binary?

In short: you can't.

You may write integer values in your source code using decimal, octal or hexadecimal notation.
For decimal notation you have no prefix and use digits from 0 to 9, e.g. 255.
For octal notation you prefix the number with '0' and use digits from 0 to 7, e.g. 0377.
For hexadecimal notation you prefix the number with '0x' and use digits from 0 to F, e.g. 0xFF.

Each example represents the same value but with different notations.

Regarding how to read and interpret the hexadecimal notation...
Each digit represents four bits, a nibble, which can hold values between 0 and 15. You simply have to get it into your spinal cord how to represent a nibble using the different notations, e.g. that 1100 in binary equals 0xC in hex which equals 12 in decimal.

Creating Items in Outlook 2007

Hi,

I am trying to notify the user about events of my application by placing an item in his outlook inbox. Unfortunately, up to now this is just a nice plan.

Is there a direct way to create pseudo-E-Mails in the Inbox? I cannot send a real e-mail, as notifcations have to be instantaneous.

It would be great if you could get me started somehow. I haven't programmed anything that accesses Outlook so far.

Thanks a lot.

m_ToolTip.Create(this);

m_ToolTip.AddTool(GetDlgItem(IDC_CC_BODY_LENGTH_MIN),"Min Body Lenght");

m_ToolTip.AddTool(GetDlgItem(IDC_CC_BODY_LENGTH_MAX),"Max Body Lenght");

m_ToolTip.AddTool(GetDlgItem(IDC_CC_BODY_LENGTH_VAR),"Max Var Body Lenght");

m_ToolTip.Activate(TRUE);

I had given like this in my code -
where IDC_CC_BODY_LENGTH_MIN,IDC_CC_BODY_LENGTH_MIN,IDC_CC_BODY_LENGTH_VAR -are edit boxes - But the appln is running into a MEMORY ERROR , Why?

Try to this code

void CDialogDlg::SetToolTip(LPCTSTR Text,HWND hwnd)
{
TOOLINFO ti;
ti.cbSize = sizeof(TOOLINFO);
ti.lpszText = (LPTSTR)Text;
ti.hinst = AfxGetInstanceHandle();
ti.hwnd = hwnd;
ti.uFlags = TTF_SUBCLASS | TTF_IDISHWND;
ti.uId = (UINT) hwnd;

m_tooltip.SendMessage(TTM_ADDTOOL, 0, (LPARAM) &ti);
}


void CDialogDlg::OnBnClickedButton1()
{
m_tooltip.Create(this);
SetToolTip("Test",hwnd);
SetToolTip("Test2",hwnd2);
}

What happens?

Hi,

Drive from the CEdit class and create a new CEditTool class, which will support the ToolTip.

In Drived class CEditToolTip, have a member of type CToolTipCtrl. Create the Instance of this member in constructor, also u can set the ToolTipText Dynamically. And Finally in the MouseMove event u can call Update to display the tooltip.

You are using same window handle as hWndInsertAfter . Refer documentation for correct parameter.
And you are giving 0 and 0 as width and height of window. (Again, refer documentation)

Having a zero width and height is fine - that is what the SWP_NOSIZE flag allows for (they are ignored), and since he also specified the SWP_NOZORDER flag, the first HWND parameter is ignored as well (I would say to "refer to the documentation", but that would be just plain scarstatic my telling that to an MVP...). His problem is with one of the other flags he sets, can you guess which one...?

Peace!
