Where to get "sys/ioctl.h"???
Thank you!!!
Rap off for you,for me,for our human.

It won't matter whether you get it or not, unless you deleted it by accident. That's because the header files contain only declarations of functions, not their implementation.
I think sys/ioctl.h is a *nix header, if you're on windows you have little chance to compile the program (without many modifications to the code).

I have to develop a multithread application.
My problem is to wait the closure of all threads
when I close my application.
I have seen that WaitForSingleObject can be used
also for threads ? Is it possible that, suppling
the thread handle to this function I can solve my
problem ?
In another way I have used an event set by the thread
when it is going to exit (the application waits for
this event after having wake up the thread) but this
solution causes a application blocking (deadlock).
Can someone help me ???
Thanks a lot !!!

afaik you can use the WaitForSingleObject / WaitForMultipleObjects to wait on thread handle for it's closure.

Hello-
I would like to build an interface with dockable pieces to it. These pieces probably most closely resemble a dialog box. That is, they have several controls as components.
I would like to construct the pieces by code -- without the dialog editor. I'm quite new to all of this, so I may be attacking this the wrong way, but I am looking at the CDialogBar class which is at least a start for dockable dialogs, but doesn't allow creation without a resource ID.
Is there a better approach? How can I create a CDialogBar without a resource ID?

hi,
Its good that i experienced the same problem. And found the solution for myself. This really works:
Here is the header file :
class cSmithChart:public CDialog
{
public:
int m_iChartSize;int m_iLineColor;
cSmithChart();
~cSmithChart();
void drawSmithChart();
afx_msg void OnPaint();
DECLARE_MESSAGE_MAP()
};
The implementation file :
cSmithChart::cSmithChart():CDialog()
{
DLGTEMPLATE *tmplate = new DLGTEMPLATE[4];
DLGTEMPLATE tmpl;
tmpl.cdit=0;
tmpl.style=DS_NOFAILCREATE |WS_CAPTION | WS_SYSMENU;
tmpl.x=0;
tmpl.y = 0;
tmpl.cx = 500;
tmpl.cy = 500;
tmpl.dwExtendedStyle=0;
tmplate[0] = tmpl;
tmplate[1].style=0;
tmplate[1].dwExtendedStyle=0;
int nresult = InitModalIndirect(tmplate,NULL);;
if( nresult == 0)
{
int error = GetLastError();
AfxMessageBox("Dialog Creation Failed");
}
};
cSmithChart::~cSmithChart()
{
};
BEGIN_MESSAGE_MAP(cSmithChart, CDialog)
ON_WM_PAINT()
END_MESSAGE_MAP()
void cSmithChart::OnPaint()
{
CDialog::OnPaint();
drawSmithChart();
}
void cSmithChart::drawSmithChart()
{
//Draw the smithchart
}
AS you could see i solved this for drawing a smithchart, which was a distributed .Lib file..
This is a production code. See if it works for you.
Good Luck.

Hi,
If you want to know more about hooking, try the article search! this[^] is just one out of many..
good luck!
A student knows little about a lot.
A professor knows a lot about little.

I am trying to send float value using Sendmessage
the source is following
float lpar = MAKEPARAM( wkpoint.x, wkpoint.y );
SendMessage( mycontrol -> m_hwnd, WM_LBUTTONDOWN, 0, lpar );
the target I want to send to is
OnMouseDownMyCtrl(short Button, short Shift, float X, float Y)
when I call sendmessage and it invokes onmousedowmyctrl event, however
what i get for x and y is totally different from wkpoint.x and wkpoint.y
any help is appreciated.

you can convert float to string and then pass the string value(address)
or you can pass the address of float
|
|
|
|
|
Thanks for your post.
If you want to conver from float to string, I have to change the parameter for OnMouseDownMyCtrl. I can't not do that since we have already put a lot code inside of this function
OnMouseDownMyCtrl(short Button, short Shift, float X, float Y)
|
|
|
|
|
float *pfVal = new float;
*pfVal = MAKEPARAM( wkpoint.x, wkpoint.y );
SendMessage( mycontrol -> m_hwnd, WM_LBUTTONDOWN, 0, (LPARAM)pfVal);
delete pfVal;
try it and let me know wheather it worked?

Thanks for your post.
Looks like it fails at SendMessage() and can't go to the even function OnMouseDown
I am still trying.

I want this to be a challenging science fair topic due for next year so it could be anything, just try to be serious about it. If this is a bother then tell me to delete it.;P (Involving computer science and either c++ or visual c++ 6)

Control something - a radio control car, a homemade robot - it neddn't be too fancy. Build a model village and run the stoplights and house lighting with the computer. Write a crypto algorithm that people can type a message into and see what comes out, demonstrating secure website principles. Or you could always do the standard volcano, erupting all over a computer.;P

In one of my science project a guy had build to control the lights and other stuff using computer program. But they were communicated by wireless system.
You need the knowledge of industrial electronics as well. This project won first price.

In our chemistry class back at school we did some sort of titation automate: reading the pH from a pH-meter, and using a computer controled syringe pump to set the pH to neutral.
But I must admit that it never really worked... 
Who is 'General Failure'? And why is he reading my harddisk?!?
