I made a simple program which when you press the up key shows up, left key shows left etc.
But how can i make it work with two keys at once? Like up and right (which would then display up and right..)
Is there some not too hard way to do this?
thanks all!

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.

with what function do i get that?
ive tried _getch, but it only catches one of the keys as some keys some dominant over others.
thanks

WM_KEYDOWN or WM_KEYUP isnt helpfuls?

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.

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.

I should have mention "relevent code".

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!

Yup, by seeing first two flags, I overlooked last parameter. My bad.

You are specifying the SWP_NOMOVE flag, which tells the function not to move the window, which is exactly what you are trying to do! You might want to add the SWP_NOZORDER flag and change the first parameter to NULL as well (sorry - did not see you already had that flag set).
Peace!

It's a user input control. It returns whatever the user set the value to.

goodmorning i am trying to type a fuction that it return me how many times a str exist in a line .Christian told me to work with CString Find but i have some problems here :/
Problem is, i think ,my while loop is wrong and my program becomes (Not Responding)
int CInfoRecoverDlg::Compare( CString line , CString str2)
{
int nCount = 0;
for (int i = 0 ; i < line.GetLength() ; i++)
{
while ( line.Find(str2,i+1)!= -1 )
{
nCount = nCount +1;
}
}
return nCount ;
}
void CInfoRecoverDlg::OnButton1()
{
CString str = "yes";
CString line = "yes i said yes , yes ";
int nCount;
nCount = Compare( line , str);
AfxMessageBox(""+nCount);
}
