Hi,

Rather than using SetCursorPos you could use the SendInput function[^]. This would allow you to set some 'extra info' for marking simulated user input.

For example:

C++

BOOL setcursorposition(long x, long y)
{
	INPUT input = {0};
	input.type = INPUT_MOUSE;
	input.mi.dx = ((x - GetSystemMetrics(SM_XVIRTUALSCREEN)) * 65535) / (GetSystemMetrics(SM_CXVIRTUALSCREEN)-1);
	input.mi.dy = ((y - GetSystemMetrics(SM_YVIRTUALSCREEN)) * 65535) / (GetSystemMetrics(SM_CYVIRTUALSCREEN)-1);
	input.mi.dwFlags = MOUSEEVENTF_VIRTUALDESK | MOUSEEVENTF_MOVE | MOUSEEVENTF_ABSOLUTE;
	input.mi.dwExtraInfo = 0xC0DEDBAD;
	return SendInput(1, &input, sizeof(input));
}

void YourClass::OnMouseMove(UINT nFlags, CPoint point)
{
	if(0xC0DEDBAD != GetMessageExtraInfo())
	{
		//You would ignore the simulated input and do your processing here
	}
	YourBaseClass::OnMouseMove(nFlags, point);
}

Don't forget to convert client coordinates to screen before calling setcursorposition.

Best Wishes,
-David Delaune

Listen here you. Mad | :mad:

This is the third time I have seen this 'question' posted. Thumbs Down | :thumbsdown:

You have not received any answers yet because you refuse to observe the forum guidelines. You will continue to receive no help until your method of enquiry improves.

Some suggestions:

1. Work out what you're trying to do
2. Work out how you intend to do this
3. Implement this plan in code.

You should NOT post a question on CodeProject when it relates to point 1.
Questions that ask about how to realize point 3 will be most favourably answered.

My 1

Consider the following contrived questions:

Q1: "I have to build a shed, with a window and shelves. It should not be very basic."
Thumbs Down | :thumbsdown:

Q2: "I am building a shed with shelves. I have selected part# XXX to fix the shelves to the wall. I am having trouble attaching this part to the walls with nails. I am trying YYY, is this the correct way to use part XXX?
Is there a better way for me to attach the shelves to the walls?"
Thumbs Up | :thumbsup:

That post came in with pure hope, optimism and joy.

I wonder what sort of fantasy dream or vision the poster was expecting from this forum. It reminds of those people that walk around and always ask if you have an extra cigarette.

I guess in the unicorn world, everyone would of pitched in to write the program, and we can all eat candy corn, or simply feed off the rock candy mountain.

I know the poster left with a dead unicorn and a rainbow of fire.

The only thing missing was delete your bookmark on the way out.

Thanks for the humor today

[SOLVED]: Error Returning CArray

hello guys... I am trying to return CArray which I create locally in a function. It simply caontains names. Now this array will be modified by other functions. Here is what it looks like

CArray<CString> CMainDlg::GetNames()
{
	CArray<CString> arrNames;
	arrNames.SetSize(10);

	arrNames.SetAt(0, "Ali");
	arrNames.SetAt(1, "Salman");
	arrNames.SetAt(2, "Zahid");
	arrNames.SetAt(3, "Mehmood");
	arrNames.SetAt(4, "Tariq");

	return arrNames;
}

But the compiler is showing me this error stating - Error C2248: Can not access private member of class CObject. Whats wrong with this code? Thanks for input.

This world is going to explode due to international politics, SOON.

Apparently you cannot use the CArray copy constructor. As a workaround you may rewrite the method this way:

C++

void CMainDlg::GetNames(CArray <CString> & arrNames)
{
    arrNames.SetSize(10);
    arrNames.SetAt(0, "Ali");
    arrNames.SetAt(1, "Salman");
    arrNames.SetAt(2, "Zahid");
    arrNames.SetAt(3, "Mehmood");
    arrNames.SetAt(4, "Tariq");
}

Veni, vidi, vici.

May be I am making mistake here but it is not working for me. Here is what I am trying using your technique.

a.h
-------------
private:
  CArray<CString> srrNames;

public:
  void GetNames(CArray<CString>&);



a.cpp
-------------
void CMainDlg::GetNames(CArray<CString>& arrNames)
{
    arrNames.SetSize(10);
    arrNames.SetAt(0, "Ali");
    arrNames.SetAt(1, "Salman");
    arrNames.SetAt(2, "Zahid");
    arrNames.SetAt(3, "Mehmood");
    arrNames.SetAt(4, "Tariq");
}

And now in a.cpp, till calling GetNames is fine. But as I said earlier, this will be modified by other functions (which are in another class). Passing it's reference is not working. How do I pass this to other function?

This world is going to explode due to international politics, SOON.

Well it means it is giving error. I am doing this.

objB.ModifyUsers(&arrUsers); // B objB;

The error it gives is:

error C2664: cannot convert parameter 1 from 'CArray<TYPE> *' to 'CArray<TYPE> &'<br />

I don't know whether should I do this or not.

ReadFile bytes read not equla to bytes requested

Hello

I am trying to get a program to work that is not written by myself. It is a serial com and the problem I get is that the number of bytes read does not equal number of bytes to read. When I try and debug I see that the struct size is 164 bytes but I am only reading 160 bytes??

I did try increasing the timeout but no difference.

thanks in advance for any help
