I got the x and y coordinates of the pointer. How can i draw a line with that coordinates. I can´t use Direct draw ( sitting on a NT station). I have some idea of catching the movement in shootergames like Q3. Then i can compare it to other gamers. Good idea? Yeeeah!
Assuming you have a Picture Box on your form:
Code:Private Sub Picture1_Click()
Picture1.Scale (-10, 10)-(10, -10)
'Draw the X and Y Axis
Picture1.Line (0, -10)-(0, 10), QBColor(9)
Picture1.Line (-10, 0)-(10, 0), QBColor(12)
End Sub
The code u sent was creating a cross, thats good. But i´m not that good. Pleease specify! I have the x and y coordinates in pixels and i want to draw a line between each of this point. It is thousands of points.
It did not create a cross, it created two lines one vertical
and one horizontal. The fact that they intersect in the middle of the picture box is a function of their x and y coordinates.The Line Command only connects two points, to continue the lineCode:Picture1.Scale (-10, 10)-(10, -10)
'the syntax is Object.Line (x1, y1) - (x2, y2)
'where x1,y1 are the coordinates to start and x2,y2 are the
'final coordinates, so the following draws a horizontal line
'because x1 & y1 both equal zero
Picture1.Line (0, -10)-(0, 10), QBColor(9)
'and the following draws the vertical line
'it is centered because x2 and y2 are zero
Picture1.Line (-10, 0)-(10, 0), QBColor(12)
to the next set of points the last set of the previous becomes the
first set of the next and so forth;
To draw a single line through a number of points you would have
to define the line or curve in the form of an equation and use the
Pset Method which in essence connects the dots defined by your x and y points.
Good LuckCode:For X = -10 To 20 Step 0.001
'Equation to Graph
Y = 2 * X ^ 2 + 5 * X - 4
Picture1.PSet (X, Y), QBColor(12) 'draw the dots

Sorry!! I´ve got a bad day. I will try the code and come back to you. Thanx...
Thank u! I got it now! Yessss!!
