.net - How to create a dump of the current ASP.NET managed process for debugging? -

-

I'm trying to debug an ASP.NET application. This is especially difficult because the bug is posted only in released code production it can not be repeated in the development or testing environment.

I am investigating the issue by creating a dump file on a particular line, where the problem is occurring. However, production environment can not be taken at any point due to business needs. This is the reason that this is also the reason that remote debugging can not be done.

Does anybody know how I compelled for a dump file is manufactured for w3wp.exe at a certain point in the managed code, still can still allow the rest of the application to be normal To operate with?

Use the rights to the web app so much and you can deploy the new code environment, You can manually create a dump file with the use of DbgHelp API: 

  [DllImport ("Dbghelp.dll", SetLastError = true)] Fixed Execution bool MiniDumpWriteDump (IntPtr ProcessHandle, Integer ProcId, IntPtr filehandle, Integer DumpType, IntPtr ExcpInfo, IntPtr UserInfo, IntPtr ExtInfo); Private static zero dump () {string outputFileName = "c: \\ mem.dmp"; Using (using FileStream stream = new FileStream (outputFileName, FileMode.Create, FileAccess.ReadWrite)) {Process Procc = Process.GetCurrentProcess ()) {MiniDumpWriteDump (proc.Handle, proc.Id, stream.SafeFileHandle .DangerousGetHandle (), (Int) 0x00000306, IntPtr.Zero, IntPtr.Zero, IntPtr.Zero); }}}

c# - ListView onScroll event -

-
I am programming a simple C # application, and I need a Scallow event on the list view. So I inherited the original ListView class created in ListviewEx witch. I found out how to locate the scroll message from WinAPI and I modified the WndProc method. Now I have this WndProc: protected override zero WndProc (Ref message message) {base.WndProc (Ref I); If (m.msg == WM_VSCROLL) {onScroll (This, New EventArgs ()); }} But the problem is, I do not know how to know about scrolling information. This data should be in wParam, but there is a LOWORD macro ++ like in C in C # and I switch to find the criteria like SB_ below, SB_ENDSCROLL, SB_PAGEUP etc. there any way Need to change the LOWORD macro from C #? Or any other way to find the necessary parameters about scrolling? You can define the WParam constants as the following: Private const int WM_HSCROLL = 0x114; Private Constant WM_VSCROLL = 0x115; Private contact int SBHOZZ = 0; Private Consultant SB_VERT = 1; Private Con...

Another option is to use and load the image.

Linux Terminal Problem with Non-Canonical Terminal I/O app -

-
I have a small app written in C to run on Linux. Part of the app accepts user-input from keyboard , And it uses non-canonical terminal mode so that it can respond to each keystroke. The section of the code that accepts input is a simple task that is called repeatedly in the loop: char get_input () {char C = 0; Int res = reading (input_tamille, & amp; c, 1); If (RSS == 0) 0 returns; If (res == -1) {/ * snip error handling * /} return c; } It reads a letter from the terminal if there is no input within a given time limit, (c_cc [VTIME] value in the vocabulary structure), read () 0 And get_input () is called again It all works very well, I have recently discovered that if you run this app in a terminal window, and then the app Close the terminal window without ending, the app will not exit Received, but CPU intensive launches into an infinite loop, where the read () returns 0 without waiting continued. So how can I get out of the apple if it runs from the terminal win...
