Positive. I can copy-paste it and run it from the console.

Then you need to do this:

BOOL b = CreateProcess(NULL, _T("d:\\path\\app.exe"), NULL, NULL,FALSE, 0 /*CREATE_SEPARATE_WOW_VDM*/, NULL, NULL,&si, &pix);

"If the executable module is a 16-bit application, lpApplicationName should be NULL, and the
string pointed to by lpCommandLine should specify the executable module as well as its arguments."

Make sure you quote the pathname if there's any spaces in it.

I've just run the same code on an old Win' 98 system and, indeed, it works perfectly.
It seems that it only fails under the Win' XP... Confused | :confused:

Using CreateProcess as documented[^] for 16-bit applications didn't help any?

From the documentation on the lpApplicationName parameter (the first one):

If the executable module is a 16-bit application, lpApplicationName should be NULL, and the string pointed to by lpCommandLine should specify the executable module as well as its arguments.

Using arrow keys, two keys at once

Johpoke18-May-07 0:23

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!

(MS Visual studio 6, program is a windows console application with mfc)

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.

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!

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.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?

{
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.
