c++ - search a Binary search tree -

I'm trying to find a name within a key, I think it's just fine. However, it has not started, maybe my code is wrong? 

  In both

main ()

(database.retrieve (name, aData)) // > 
  Fixed zero recovery item (four * names, data, and adata) {cout & lt; & Lt; "& Gt; & gt; retrieve & lt; & Lt; Name & lt; & Lt; Andal & lt; & Lt; Endl; If (database. Retrev (name, adata)) // match name in both name and adata is matched & lt; & Lt; Adata & lt; & Lt; Endl; And cout & lt; & Lt; "Did not get \ n"; Cout & lt; & Lt; Endl; } Fixed zero void item (four * names) {cout & lt; & Lt; "& Gt; & gt; remove & quot; & lt; & Lt; Name & lt; & Lt; Andal & lt; & Lt; Endl; If (database. Extract (name)) cout & lt; & Lt; Name & lt; & Lt; "Deleted \ n"; And cout & lt; & Lt; Name & lt; & Lt; "Did not get \ n"; Cout & lt; & Lt; Endl; } Int main () {#ifdef _WIN32 // Request a memory leak report in the output window after main return _CrtSetDbgFlag (_CRTDBG_ALLOC_MEM_DF | _CRTDBG_LEAK_CHECK_DF); #endif data a data; & Lt; & Lt; "Databases of great computer scientists \ n \ n"; Database.insert (Data ("Ralston, Anthony"); Database.insert (Data ("Liang, Lee")); Database.insert (Data ("Jones, Doug")); Database.insert (Data ("Goble, Colin")); Database.insert (Data ("Nith, Donald"); Database.insert (Data ("Kay, Alan")); Database.insert (Data ("von Neumann, John")); Database.insert (Data ("Tryboboff, Michael"); Database.insert (Data ("Turing, Allen")); DisplayDatabase (true); Recovered item ("Tryboboff, Michael", Edata); Recovered item ("Kaya, Danny", Edata); RemoveItem ("Ralston, Anthony"); DisplayDatabase (true);

Retrieve function ... 

  bool BST :: Recover (const char * key, data & amp; aata, int parent) const {For (int index = 0; index & lieutenant + message + 1; index ++) {if (item! [Index] committee {if (item [index] .instanceData == key) {aData.setName (key ); Back true; // not returning correctly}}}}

and defined in data.cpp 

  bool operator == (CONST Data & amp; D1, CONST Data & amp; d2) {return strcmp (d1.getName (), d2.getName ()) == 0; }

So this is the bit of code inside the main () where it has not been said when I think that it should work correctly both names and the correct name in Eta which is Was found. 

  Fixed zero recovery item (four * names, data, and adata) {cout & lt; & Lt; "& Gt; & gt; retrieve & lt; & Lt; Name & lt; & Lt; Andal & lt; & Lt; Endl; If (database. Retrev (name, adata)) // match name in both name and adata is matched & lt; & Lt; Adata & lt; & Lt; Endl; And cout & lt; & Lt; "Did not get \ n"; Cout & lt; & Lt; Endl; }

You must use BST to navigate through the paste - each But do not looping items in your array, like others have said. Try something like: Recover 

  bool retrieve (key, Adata) retrieve (key, Adata, guardian) real false hair if (key == Aata) returning to (key , Adata, guardian) if (key == item [parent] Knam) ADataksetName (key) and if (keys & lt; item [parent] Knam) retrieve (key, Adata, 2 * Basic + 1) Other received (key, etata, 2 * parent + 2)

This should work well! :)

c# - How to capture HTTP packet with SharpPcap -

-
I would like to capture all incoming HTTP packets on my machine. To do this, I am using SharpPcap which is a WinPcap The cover is. SharpPcap works very well, but it captures TCP packets and what it wants to do for me is a very low level. Does anyone know how can I easily get full HTTP requests / reactions from all these TCP packets? Thanks SharpPcap is already able to capture the packet in the same way That's what the virus does (just in the code instead of the GUI). And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes. All st...

php - Multiple Select with Explode: only returns the word "Array" -

By using Wordpress I have created a multiple selection box so that users can select categories to exclude. When the page is initially loaded, I see my predefined default option. However, when I select a new value and I save ... I only see the word "Array" and have not chosen anything else? & lt; Class = "amultiple" id = "& lt; php echo $ value ['id'] ;? gt;" name = "& gt; php echo $ value ['id'] ;; gt; []" Multiple = "multiple" size = "8" & gt; & Lt ;?

jquery - SimpleModal Confirm fails to submit form -

-
I am trying to confirm jQuery to show yes / no confirmation when I submit a form. I had modified (in the last list) to capture and block form submissions. However, it only works with jQuery 1.2.6, a recent upgrade stops 1.3.2, if yes is clicked, then by submitting the form. But I can not understand what is wrong / inconsistent in my code now. Demo (which works in both versions of a simple window.href implementation). $ (document) .ready (function () {$ ('input.delete'). Click (function (e) {e.preventDefault (); var target = $ (e .target); Confirm ("Really delete this event?", Function () {target.click ()});});}); How about something like this? The idea of ​​catching clicks (and fire!) On the submitted event is not click event. $ (document) .ready (function () {$ ('# myForm'). Submit (function () {var f = this; Confirm (" Remove? ", Function () {$ (f). Submit ();}) Return; Return the initial session;}}}}; Hope That this is som...
