• Media Foundation: Custom Media Source features

  - by Ivan Dyachkoff

  With IMFMediaSource and IMFByteStreamHandler I can access bytes from media source to determine media type and audio/video stream parameters, such as duration, quality, number of streams, etc. But can I replace these bytes and send them back to client? E.g. I receive zip file bytestream, extract actual media and send another bytestream with asf (for example) data. Is this possible?

• Windows PE - Where and how are strings stored if not in resources?

  - by sdadsas

  Usually strings (like content/titles of dialog boxes) in .exe files are stored in some sort of resources. But in some recent exes I disassembled/resource-inspected I couldn't find any resources containing the string but it was somehow hardcoded with db's into the program source code. How can I extract and modify strings directly located in the program? I assume those are just the equivalent to const char*s in C++? Why would someone not "outsource" the contents of dialog boxes, menus, etc?

• T-SQL String Functions: difference between using Left/Right and Substring and strange behaviour

  - by TheObserver

  I am using SQL Server 2008 & 2005 (Express). I'm trying to extract part of an alpha numeric string from a varchar field. RIGHT(str_field,3) yields null values but substring(str_field, len(str_field)-2, len(str_field)) gives the right value. left(str_field,7) gives the expected values. What gives? I would have thought that RIGHT(str_field,3) and substring(str_field, len(str_field)-2, len(str_field)) are equivalent expressions.

  When using the cgi module in Python, I can't seem to figure out how to extract CGI variables in the URL. For example if the url servercgi.py?name=user , how do I get 'name' after import cgi?

• C# XElement: Node Formatting with HTML

  - by Arnej65

  I'm extracting XML node from an XElement. When I use XElement.Value it strips any HTML that may be in the node. I know that if I do XElement.ToString() I can keep the HTML, but it also gives me the node tags. Is there any way to extract the content of a Node as is without the HTML being stripped out? Cheers.

• Accessing the MSP and PSP registers of the Cortex-M3 in C/C++ code using Keil's µVision

  - by Captain NedD

  I need to access the MSP and PSP registers (the main and process stack registers) of the Cortex-M3 processor. I'm writing in C/C++. The µVision and associated compiler doesn't let you do inline assembly for this Thumb-2 only core (and I'm not sure that'd be such a good idea anyway). I need to do this so that I can extract the immediate value of an svc instruction regardless of whether it was executed while in thread or handler mode. Thanks,

• How can I diff two files and report the section the diff occurs in?

  I have two text files with several sections in them. Each section has has a header with the section name (grep can extract all the section names without extracting anything else from the file). How can I report the differences between the two files AND report the section that the difference occurs in? I would also need to be able to report added/missing sections. Ideally, identical sections would not be mentioned in the report at all.
