sw2009 api sldworks.activatedoc2() causes background sw to become visible
hello,
my vb.net program is running sw in the background, no problem initially, as sw stay invisible while it opens some files and outputs .dxf, .pdf versions ,etc.
...but then when the activatedoc2(....) method is called on an assembly, all of a sudden sw becomes visible in the backgound.
i have used
sldworks.usercontrol = false
sldworks.visible = false
...right at the beginning of my code, and sw does stay invisible for quite a good portion of the processing, but when the activatedoc2 () method is called to activate an assembly, sw suddenly makes itself visible?
code below:
