Isvalid (objectname) used to determine whether the objectname object effectively, normal use objectname to instance name must be in, but if the objectname is variable, how to judge, now use case for the need through windows_name this variable to open a window, but open to judge windows_name before this variable represents the window at the open window is already open, if you open will be windows_name maximize the window, if it is not open open windows_name variables represented by the window, looking forward to give directions, thank you for help!!!!!

CodePudding user response:

Every open a window, the window windows_name variables into the array, again opened, in array to iterate over the windows_name exists, there is maximum, no open bai;
