Environment : TestComplete 12 I am facing a issue wherein when I run a keyword individually the drag operation drags from the centre of the object but when I run the same keyword in terms of a test ( as in there are a few keywords above it performing some operation ) the drag point is from the left top of the object . Because of which when I perform the drag operation with certain horizontal pixel value it doesn't reach the required position . I have attached a snapshot as an example . can someone please help me out on this.

In all mouse operations (Click, Drag, HoverMouse, etc.) -1,-1 means the object's center point. So in your example the dragging should start at the center of the PM.PMShell.ListViewItem object. Does this ListViewItem point to the same object in both scenarios? To check that, add Log Message before the drag and log the ListViewItem's FullName property (set the MessageText parameter to the Object Property mode, then pick the object and property).

On a related note, it's better to avoid hard-coded drag distance and calculate it dynamically based on the target object location. This can be done as follows: // Drag from the center of object A to the center of object B start_point = A.WindowToScreen(A.Width/2, A.Height/2); target_point = B.WindowToScreen(B.Width/2, B.Height/2); dragX = target_point.X - start_point.X; dragY = target_point.Y - start_point.Y; A.Drag(-1, -1, dragX, dragY);

OK... question... If you put a breakpoint on your drag that's coming from the Excel, what, exactly, are the values for those first two co-ordinates? For some reason, it seems that they are being translated as '0' instead of '-1'. This could potentially happen if the column that they are coming from is being read in as a string and not as integers.

What tristaanogre says sounds distinctly possible. Especially if you are using the DDT driver. This tends not to happen so much if you use Excel via COM. This is due to the way the DDT driver determines what type of data a given column contains. If you have mixed types in a single column, it can get confused quite easily. If it's not converting them to 0's, I guess the other possibility is it's getting the incorrect object at runtime?

Heh. That's pretty much what I do. The target point is set by the user in the input data so I kind of have to really ....

Can you show us a screenshot of the drag operation in your keyword test? That would help determine if there is a setting or operational parameter set wrong.

    I'm kind of guessing here, but I'm not sure about -1 as the Client X/Y co-ordinate?
    
    I use drag and drop. To determine where I need to click (I always want the centre point), I get the Width and Height of the object to be dragged and divide those by two. Which gives me the centre point. The objects being dragged by my script can be of various different sizes, so I have to calculate the click point myself. (Of course, I also have to calculate the destination point as well. But that's a slightly different matter.)
    
    I can't see how "-1" could be a valid value for this (as these co-ordinates represent a point within the object to be dragged so the top left corner should be 0,0). But it obviously allows it. But I'm not sure where -1,-1 will put the mouse pointer, and I didn't see anything in the Drag method documentation that tells you this either.
    
    Or possibly HKosova may be able to tell us what it's doing with the -1's you currently have in there?
