assembly - Intel Stack Growth and Reference -

-

I have some questions related to Intel IA-32 stack. Specifically:

  1. When I put a value on the stack push , the stack pointer is reduced by the value of the pushed value (% esp - size ), and the value is stored on the old value of % esp .
  2. If I write without pop> , I need to increase the stack pointer (% esp + size ).
  3. Rather than adding the required size to the stack, it is my perception that when it happens, I want the value away to towards Instead of going from the indicator address.
  4. For this reason, someone else will pick up the poorly read data.

    Is the logic given above me right? thank you in advanced.

    1. Wrong, new has been written on% esp value.
    2. Due to the wrong, # 1 point: You can read your most recent value from (% esp) . You need to add % esp to access older items.
    3. This code is just allocating a block of memory from the stack as a local storage. The block is filled later.
    4. Not sure what you mean.

I know that the query is quite messy Edit: I realized that there are two questions to be needed, so I have strictly modified a question question table data tables ss_users user_id FIRST_NAME LAST_NAME admin_level user_approved 1 Nick Jones 0 1 2 Johnny Rocket 0 1 table ss_user_profile_status user_id photo_uploaded 1 1 2 1 table ss_user_photos selected user_id file name photo_id 1 1 photo_1 .jpg 1 2 2 photo_2.jpg 0 3 2 photo_2.jpg 1 table ss_general user_id city state zip neighborhood 1 Baltimore maryland 00125 hamsterdam 2 Lekland My 11542 treemont table ss_languages ​​user_id French German Italian Spanish 1 0 1 0 1 2 0 1 1 Table ss_experience Waldorf Kumon homeschooling user_id 1 0 1 0 2 0 0 1 My current The result is that all users, which should not be the case: ...

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i...
