And of course the same up and down arrows don't exist in 2.62/2.80 Otherwise it'll work the same for 2.62/2.80 as PLUS 12. Rich.... wrote in message news:C7pYvtLjUHA.1832@ip-AC1E04A7... Instead of passing the hWnd of the button, I changed it to pass a object reference. That way you can test to see which entryfield has focus via a API. If neither has focus it'll just return. And it makes it easier to update the appropriate entryfield. Added nMultipler in case you wanted a different jump. Changing it to 10 will give you a jump of 10 each time. I didn't localize any of my variables or test every combination but this might get you started down a different road than previous test forms.

Rich... wrote in message news:$ym54QLjUHA.1832@ip-AC1E04A7... I took the liberty of taking the demo2b.wfm and altering it along the lines of the WhileMouseDown functionality. I stripped most everything out of the form and just left the controls and a new downbutton function. I'll leave it up to whoever want to experiment with it to add more functionality. When either button is pushed it will add or subtract 1 to the value. If held down it will repeat adding or subtracting 1 to the value. The repeat speed is slowed down by using sleep so you can adjust how fast it repeats. I pulled the routine out of one of my controls that simulates a spinbox but I also use it to scroll though a table. Rich... "Tom"  wrote in message news:O8yEiBLjUHA.1352@ip-AC1E04A7...

The WhileMouseDown Class When the left mouse button is pushed and held down over an object, the latter’s onLeftMouseDown() event is fired only once.  If we want an action to be repeated while a button is pushed, we could create a loop in its onLeftMouseDown() event and break that loop when the mouse is released.  However, that solution is hazardous:  if the mouse is dragged outside the surface of the button and then released over another object, we could end up with an infinite loop. For dBL developers, the real solution is to use a free component designed by Romain Strieff and Ronnie MacGregor:  their WhileMouseDown class.  This object does use a loop.  However, in that loop an API call is made to check if the mouse button is still pushed over the button: if it is not, the loop is broken from within the onLeftMouseDown() code, thus preventing the hazardous situation we’ve just spoken about. Being a visual component, this class can be made available from the Component palette, and then can be drag’n dropped onto a form under the Form designer. Thanks, Tom
