vb.net - Common class to few forms -

-

i find nice code making form semi transparent while moving. have multiproject solution 1 project common other , compiles dll referenced projects. code making form semitransparent needed few forms in every project not forms.

i have problem on , how use code used forms. code:

imports system.componentmodel  public class clstransform inherits system.windows.forms.form  private _opacityresize double = 0.5 private _opacitymove double = 0.5 private _opacityoriginal double private const wm_nclbuttondown long = &ha1 private const wm_nclbuttonup long = &ha0 private const wm_moving long = &h216 private const wm_size long = &h5  protected overrides sub defwndproc(byref m system.windows.forms.message)     static lbuttondown boolean      if clng(m.msg) = wm_nclbuttondown         lbuttondown = true     elseif clng(m.msg) = wm_nclbuttonup         lbuttondown = false     end if      if lbuttondown         if clng(m.msg) = wm_moving             if me.opacity <> _opacitymove                 _opacityoriginal = me.opacity                 me.opacity = _opacitymove             end if         elseif clng(m.msg) = wm_size             if me.opacity <> _opacityresize                 _opacityoriginal = me.opacity                 me.opacity = _opacityresize             end if         end if     elseif not lbuttondown         if me.opacity <> _opacityoriginal me.opacity = _opacityoriginal     end if     mybase.defwndproc(m) end sub  public property opacitymove() double ... etc...  public property opacityresize() double ... etc...

i try make class clstransform under common project creates me new form.

how configure class used forms?
, how put it?

i'd suggest making clstransform abstract marking mustinherit. then, in other forms, inherit clstransform instead of system.windows.forms.form. every form inherits clstransform have transparency effect.

as put file itself: doesn't matter. don't forget add project reference project contains clstransform in every project needs use it.
