c# - If form is moving then -

i need alternate value of boolean var.. if form moving myvariable false , if form not moving myvariable true.

i've tried can click in border of app move app , code not work expected 'cause affect if click in clientarea:

private sub form1_mousedown(sender object, e mouseeventargs) handles mybase.mousedown     timer_flag = false end sub private sub form1_mouseup(sender object, e mouseeventargs) handles mybase.mouseup     timer_flag = true end sub 

also i've tried move event , locationchanged... don't know how detect if form moving or not.

i believe post winforms window drag event answered question. elektro hacker, keep work.
