.net - What is the correct C# interop code to handle this structure and method? -

-

I am writing a managed wrap around an unmanaged DLL, and I want to do the following method and structure correctly Marshall I'm unable to Here's what .h file for unmanaged code: 

  typedef struct {WORD PI_code; Dedworld's GrafStat [31]; BYTE PTY_code; Four * ps; Four * RT; } RdsData_t; COMPANYNAME_API Zero COMPANY_get_rds_data (RdsData_t * rds_data);

And here's what I did, P-Invok Interop with some help from assistant: 

  [StructLayoutAttribute (LayoutKind.Sequential)] public structure RdsData_t {/// WORD- & gt; Signed small public use PI_code; /// Deedwards [31] [Marshlasatribut (unmanaged type. Bevlarere, Size Knnst = 31, Aeresbteep = unmanaged type U 0.4)] public UIT [] Jiarpitat; /// byte-> Unsigned four public byte PTY_code; /// four * [UnmanagedType.LPStr]] Public String PS; /// four * [UnmanagedType.LPStr]] public string RT; } [DllImport ( "companyname.dll", EntryPoint = "? COMPANYNAME_get_rds_data @@ YAXPAURdsData_t @@@ Z")] private static extern void COMPANYNAME_get_rds_data (ref RdsData_t data);

However, through it throws a AccessViolationException when called discovery and experimentation, I am able to come up with something that does not take exception, but the data is wrong or Unavailable, to believe me that they are not right or not correct

What should I use the interop code for the above structure? Is there any tool other than Pinevoc Helper that can use to help me?

Thanks in advance!

try the following 

  [StructLayoutAttribute (LayoutKind.Sequential)] Public Unsafe Structure RdsData_t {/// WORD- & gt; Signed small public use PI_code; /// Deedwards [31] [Marshlasatrybet (unmanaged type. Bevlarere, size Knent = 31, Arresbteep = unmanaged type U 0.4)] public certain units Grupstat [31]; /// byte-> Unsigned four public byte PTY_code; /// four * [UnmanagedType.LPStr]] Public String PS; /// four * [UnmanagedType.LPStr]] public string RT; }

Note: However, you will need to have your library / app perform unsecured code so that it does work.

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.

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
