The same sprite as this topic's about. now, i want to drag the sprite.. we (fire2burn and me) have bin working for 2 houres now to get this fixed. we got the following code:

public void OnPaint(Device device, string title, string text)
    {
        // if mouse down and drag window, x and y pos changes
        cMouse muis = new cMouse();
        muis.Update();
        if (muis.LeftButtonDown)
        {
            int curx = cTools.FormHandle.PointToClient(Cursor.Position).X;
            int cury = cTools.FormHandle.PointToClient(Cursor.Position).Y;

            if (cTools.FormHandle.PointToClient(Cursor.Position).X > xx &&
                cTools.FormHandle.PointToClient(Cursor.Position).X <= 350 + xx &&
                cTools.FormHandle.PointToClient(Cursor.Position).Y >= yy &&
                cTools.FormHandle.PointToClient(Cursor.Position).Y <= 150 + yy)
            {

                if (!Dragger)
                {
                    tempx = cTools.FormHandle.PointToClient(Cursor.Position).X;
                    tempy = cTools.FormHandle.PointToClient(Cursor.Position).Y;
                    Dragger = true;
                }
                else
                {
                    xx = curx - tempx; //curx = tempx
                    yy = cury - tempy; // cury = tempy

                }
            }
        }
        else
        {
            Dragger = false;
        }

        frmSprite.OnPaint(device,xx,yy,350,150); // 350, 150
        frmButton.OnPaint(cTools.FormHandle, new System.Drawing.PointF((xx + 350) - 110, yy + 97), new System.Drawing.SizeF(87, 29), "OK");
        frmCaption.OnPaint(title, xx + 40, yy + 13, System.Drawing.Color.White);
        frmText.OnPaint(xx.ToString() + "," + tempy.ToString(), xx + 25, yy + 40, System.Drawing.Color.Black);
        //frmText.OnPaint(text, xx + 25, yy + 40, System.Drawing.Color.Black);

    }

we have problems with these 2 lines

xx = curx - tempx; //curx = tempx
yy = cury - tempy; // cury = tempy

cuz, cury and tempy have the same value.. same with curx and tempx.. Kind regards djnevs and Fire2Burn

You might be rendering via D3D, but I don't see anything DX specific to your question. Looks like a simple case of debugging some variables and logic - moved to 'For Beginners'.

There are various bits of your code that don't make much sense:

You've creating a cMouse object but then appear to get mouse coordinates from Cursor.Position ??

Where are xx,yy,tempx,tempy declared - what other code reads/writes them?

If the values in your suspected statement are wrong, use your IDE to set up on-change breakpoints and see where they're getting changed. Then work out why they're getting changed.
