i need update fdf request input steam before saving it, programmatically on server side. using itextsharp library. fdfreader gets data fine , can move writer there no acrofields property on fdfwriter. , acrofields property on fdfreader readonly, can't before setting fields.

i need able set field's property hidden. this:

vb.net

dim reader fdfreader = new fdfreader(request.inputstream) dim writer fdfwriter = new fdfwriter  writer.setfields(reader) reader.close()  writer.acrofields.setfieldproperty("key", "setflags", pdfformfield.flags_hidden, nothing)  '  (add save file here)

but writer.acrofields not exits. how field properties set fdfwriter?

how field properties set fdfwriter?

they not. object allows retrieve , fill in fields throug code pdfstamper. have @ example: http://developers.itextpdf.com/question/how-save-xfdf-file-pdf-file

unity3d - Rotate an object to face an opposite direction -

i have object , b. when click on object b, rotates object b (a faces b). b doesn't face a. need following : when faces b, need face opposite direction. have code rotating @ b. how rotate face opposite direction after that? vector3 targetdirection = target - transform.position; float step = speed * time.deltatime; vector3 newdirection = vector3.rotatetowards (turretdome.transform.forward, targetdirection, step, 0.0f); turretdome.transform.rotation = quaternion.lookrotation (newdirection); you object facing object b, want inverse direction of object after that? objecta.transform.rotation = quaternion.inverse(objecta.transform.rotation) but lets assume example turretdome object a, (negate direction): turretdome.transform.rotation = quaternion.lookrotation (-newdirection); naturally, both of these snippets not show how smoothen rotation, seem know how use time.deltatime. just incase unsure, quaternion.lerp this
