c++ - Combining multiple functions to single generic function -


i have couple of function initialise interface pointer , each function initialise pointer particular version. have make these functions single generic function.

bool init_9(mstsclib::imsrdpclient9* iface) {     iface->putsomedata1();     iface->putsomedata2();     iface->putsomedata3(); }   bool init_8(mstsclib::imsrdpclient8* iface) {     iface->putsomedata2(); }  bool init_7(mstsclib::imsrdpclient7* iface) {     iface->putsomedata1();     iface->putsomedata3(); }

i want know if there better implementation below prototype because each statement require explicit casting of interface pointer , visual studio intellisense have hard time fetching details.

bool init(void* ptriface, int version) {     void* iface; // todo: make type required version      // cast iface @ run-time according version number     // switch(version){}     iface = reinterpret_cast<mstsclib::imsrdpclient9*>(ptriface);     iface = reinterpret_cast<mstsclib::imsrdpclient8*>(ptriface);     iface = reinterpret_cast<mstsclib::imsrdpclient7*>(ptriface);      // switch(version){}     iface->putsomedata1();     iface->putsomedata2();     iface->putsomedata3();     iface->putsomedata4();     }

seems you're looking function overloading:

bool init(mstsclib::imsrdpclient9*); bool init(mstsclib::imsrdpclient8*); bool init(mstsclib::imsrdpclient7*);  bool init(mstsclib::imsrdpclient9* iface) {     iface->putsomedata1();     iface->putsomedata2();     iface->putsomedata3(); }   // ...

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

angular - Is it possible to get native element for formControl? -

i've got angular2 reactive form . created formcontrol s , assigned input fields by [formcontrol]=... . understand creates nativeelement <-> formcontrol link. my question: possible nativeelement formcontrol ? wanna myformcontrol.nativeelement.focus() i can share 1 terrible solution works me. in reactive forms can use either 1) formcontroldirective ts mycontrol = new formcontrol('') template <input type="text" [formcontrol]="mycontrol"> or 2) formcontrolname ts myform: formgroup; constructor(private fb: formbuilder) {} ngoninit() { this.myform = this.fb.group({ foo: '' }); } template <form [formgroup]="myform"> <input type="text" formcontrolname="foo"> </form> so these directives write patch like 1) formcontroldirective const originformcontrolngonchanges = formcontroldirective.prototype.ngonchanges; formcontroldirective.proto
