windows - DbgPrint in Memory Dump? -

-

I have a driver who avoids BSOD directly and with some colored dots and strips, the windows vista's screen is black Converts to Color. I'm getting a memory dump on the system later and DBeegie has shown me a stack trace (stating that it can be a distorted pile and some parts may be wrong) Mercy is that the commands found in the stack may be somewhere Do not even see those who are clearly breaking the whole thing. (I can leave my entire routine but can not leave some parts of it.)

One way to read any debug messages in a external debugger to get them out of memory dumps or serial ports Knows (My exam system stalls if the debugger is connected, but it can not be enough for me to know more about remote kernel related debugging.)

I would like to know the point where my code Fails, because it looks ok to browse through the code by me, I'm getting a little bit useless and I might need a hint.

Details about how to set up your debugging session.

The setup process is:

  1. Setup 2 pc, first its developed environment and second that is the debug target. (Vista + Vista64 works best for me)
  2. Set up debugger connection using a firewire cable or null-modem cable (Null-modem almost always works, but the firewire can be viewed from a display standpoint The USB is expensive and does not come out of the box for me ...)
  3. The target computer has 'debug mode'
  4. Running WinDbg and waiting for a kernel connection Debugging the target computer Boot in Od.
  5. While boot-up, WinDbg should print messages about the target system. Here you will see DBG print message etc. (All DBP print is disabled per default in XP (not in XP), and you have to enable it)
  6. You can define the breakpoint and set the breakpoint in the module in the widget.

PS: bcdedit sometimes fails to setup debug mode, why I do not have any clue. But it seems that in a certain order you should tell it to debug parameters. Working combinations are trying different combinations ....

When you break into the process you can use the command in WinDbg. A pair of interesting people:

  • LM displays all currently loaded modules
  • LM M pattern Satisfying all the modules lists the symbols in search mode (such as "LM M Kernel 32 *"
  • X Module_Now! Function_Name_Paton (like "Kernel 32! * ")
  • BP module_name! Function_name specified function
  • "
  • The help for .reload / u shows the X.sys x.sys module reloads the debug settings. (When you want to rebuild your project, And 'x.pdb ...' then it is helpful).

Enable all DBG print output under Vista:

enable_dbg_print_vista .reg 

  Windows RT Istry Editor Version 5.00 [HKEY_LOCAL_MACHINE \ SYSTEM currently Kantrolset \ Control \ Session Manager \ Debug Print Filter] "default" = Divord: 0000000 F

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...

PHP - get image from byte array -

-
I am trying to create a back-end for my mobile application. I am sending the content of an image in the body of the HTTP request (output stream) as a byte array, I want to read this stream of bytes in PHP scripts and take back an image. Can anyone tell me how can I do this? Thank you. You can obtain the request body $ body = Reading from file_get_contents ('php: // input'); What you do with that data Depending on you, you can write the data in a file as you mentioned that this is image data, you can drop the data into the object can do. 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...
