c# - Excel file with multiple sheets from SSRS Reports -

-

Assume that I have 3 bytes of arrays, each representin a .xls file I give them a single XLS file with 3 sheets How can I add in SSRS reports are very rich and do not include charts objects.

Performance is not important so I can save them on disk as necessary, as the last resort, I can also use excel macros (if I knew how to do it). I tried to use microsodt.office.interop.excel, but I could manage to add a new sheet to only one file, I could not add an existing sheet

Any help would be appreciated.

Here is a method that writes a byte in the form of a letter for a specific workbook: 

  Public Static Zero WriteToSheet (String Target Bookpath, Byte [] fileBytes) {try {Object x = Type.Missing; Create a temp file to encapsulate the // byte array string tmpPath = IO.Path.ChangeExtension (IO.Path.GetTempFileName (), ".xls"); My.Computer.FileSystem.WriteAllBytes (tmpPath, fileBytes, Incorrect); // Start Excel Application (COM) Excel.Application xlApp = new Excel.Application (); // Open Target Book Excel Workbook Targetbook = XLAP Works. Open (targetbooks, x, x, x, x, x, x, x, x, x, x, x, x, x, x); // Open Temp file with Excel Interop Excel Workbook Sourcebook = Xlap Works. Open (TmPath, X, X, X, X, X, X, X, X, X, X, X, X, X, X); // Receive a reference for the desired letter excel. Worksheet source sheet = (Excel Worksheet) sourceBook.Worksheets (1); // Workspace Copy the temp sheet specified in the form of the "first" parameter in Excel. Worksheet target = first (Excel.Worksheet) targetBook.Worksheets (1); Try it before {SourceSheet.Copy (target, X, X); Save // ​​Close and close the sourcebook. Close (wrong, x, x); Targetbook.Close (true, x, x); XlApp.Workbooks.Close (); XlApp.Quit (); } Hold (exception before) {Debug.Fail (ex.ToString); } Finally {// Release COM Objects / Source Source (SourceSheet); Destroy (source book); // Destination goal (first goal); Destroy (targetbook); // app destruction (xlap); } // Kill the antidote file. My.Computer.FileSystem.DeleteFile (tmpPath); } Hold (exception before) {Debug.Fail (ex.ToString); }}

The DESTROY method releases COM stuff, which is very important: 

  public static zero destruction (object o) {try {system. Runtime .InteropServices.Marshal.ReleaseComObject (O); } Hold (exception before) {Debug.Fail (ex.ToString); ErrorLog.Write (ex.ToString); } Finally {O = zero; }}

If I understand correctly, then you have to:

  1. Create a new workbook
  2. Loop's Byte Arrays
  3. Call WriteToSheet for each byte array

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
