Cursor positions

[richiemac]

Hi all, I have a form where I want to set some regions. When the mouse moves over these regions I want the cursor image to change. My idea is to set up some rectangles and use the mousemove event (somehow) to check against the current position of the cursor. I just want to know what properties do I need to use for this and is there a better way. I suppose I'm basically asking how I can check if the mouse is over a certain area of a form. Thanks in advance Rich

Try override event MouseMove to get mouse position. Or use MouseEnter, MouseHover or MouseLeave event to evulate if mouse is in or on certian controls.

So I've got a rectangle that defines an area. How do I then check whether the mouse position is in that area. I've tried using, myRec.Contains ( this->MousePosition ); but it doesn't seem to use the whole area. It only seems to work at a certain spot. I'm obviously misunderstanding something.

I have found the problem. MousePosition gets you position, point 0,0 top left of the creen, not the form. There is work around this problem.

#include //Win32 header

RECT *rect = new RECT(); //Create Rectangle Win32 Syntax
HWND hWnd = GetActiveWindow(); //Gets Handle of current Form
GetWindowRect(hWnd, rect); //Gets Position of the form

// Get Mouse position and calculate to form cordinate
int x = this->MousePosition.X - rect->left - 4;
int y = this->MousePosition.Y - rect->top - 30;

//Check if the mouse is insade the rectangle
if (myRec->Contains(x, y) == true)
label1->Text = S"True";
else
label1->Text = S"False";

ps: Overridng Those event like MouseEnter, and other i have posted will work only if it is a control. I have reread and now i anderstand what you have ment.

Thanks for the help. I'm having trouble firstly with the drawing or placement of the rectangle. It's not in the correct place - for instance, if I draw a picturebox with the same coordinates they are in different positions on the screen. Very confused as to why this is - so I assume from your previous post they are being drawn with different relative positions. So I've tried to use the work around you posted but if I include the windows header I have a lot of problems with my message boxes and some other components that I need. Is there no way of doing the same thing without the need for the win32 api.

Sorry, I can't get that error. Try to make another unmanaget class with old syntax:

#ifndef _MPOINT_H_
#define _MPOINT_H_
#include

struct pointMData
{
int x;
int y;
};

class MPoint
{
public:
MPoint(void){}
~MPoint(void){}

void GetPoint(pointMData \*pData)
{
	RECT \*rect = new RECT();
	HWND hWnd = GetActiveWindow();
	GetWindowRect(hWnd, rect);
	pData->x = rect->left;
	pData->y = rect->top;

	return;
}

};
#endif

This is unmanaged class, so i have created pointMData for retreaving, because i have a problem using Rectangle in umanaged class. If this doesn't work, then try Creating Win32 DLL. quote: Is there no way of doing the same thing without the need for the win32 api. I couldn't find in framework for this workaround, so i used Win32 api. I don't know if exist. ps: i hope this works
