Common Developing mistakes.. How to avoid !!

Alsalam alikom wa ra7mat Allah wa barakatoh

I've read a gr8 article in MSDN and I thought to share it... here r some quotes from it

- Load other forms in the background and populate controls with data before using the Show method.

- Use an off-screen bitmap. For an example, see How to: Draw Images Off-Screen.

- Override the OnKeyDown, OnKeyPress, and OnKeyUp methods on controls instead of adding key event handlers.

- Avoid using the ToString method of an enumeration because of the performance impact it incurs by searching metadata tables.

- Strings are immutable, so a new String object is created every time you modify the string. Consider using a StringBuilder when constructing a string that will be modified often.

- Use the ParseExact method for a DateTime if you know the exact format used for DateTime serialization. Otherwise, the DateTime parser will sequentially try to apply several culture-specific formats.

- Whenever possible, specify the size of your collection, because dynamic resizing can greatly increase excess storage.

- Use generic collections to avoid the boxing and unboxing overhead for value types. Defining your own optimized collection results in the best performance.

- Avoid virtual calls.

- Use fields instead of properties where possible.

And here is a link to the Article

Those points in bold attracted me...

Exploiting Double Free Vulnerabilities...

Alsalam alikom wa ra7mat Allah wa barakatoh

Huh!! that's what I said when I first saw that title... but let me explain...

Double Free means that you try to free a pointer two times (which is logically can't work).
Actually windows SP2 and later (even Vista) this can be done (in somehow) and can actually corrupt the heap (Vista will shout at your face if u did) and that can make you able to use and browse the heap as you want..

Facts to know about how Windows frees your pointers:
- There is something called Lookaside buffer (fast access, small size) and another thing is FreeList(slower access, the whole memory).
- Chunk is an object of the DataStructure that holds mainly 2 things: pointer to where the next free Chunk is and pointer to the previous free one (think about it like a node in a linked list)
- The first 4 bytes of the Chunk is the BLink (BackLink) and the second 4 bytes is the FLink
- delete ptr1;
delete ptr2;
Windows takes your Chunk (for ptr1) and puts it in the Lookaside s…

Windows7 adds Math Input Panel

Alsalam alikom wa ra7mat Allah wa barakatoh…I was reading a windows team post about Input Panels improvements in Windows7 [here]. When at the end I saw a very interesting –intuitive if you wish- new thing… which is, as you guessed, the Math Input Panel…Yes, that crappy font is mine… I “drew” that by mouse as I don’t have a tablet pen/pc.You can then paste it directly into word and it’ll recognize it as an editable equation…During my tests, the output panel (the top part) hanged, but I liked that the drawing panel was still responsive and I could still write/erase… till the top one started to respond again…One other thing to know, after you click Insert (that button down there) it copies the equation in MathML [Wikipedia link] format.. which is a standard way of representing equations and hence any application that recognizes the format can insert it not as an image but as a nice editable equation…If you think it recognized something wrong, you can click “Select and Correct” then draw …

Visual Studio 2008 Not saving changes or project properties?

Alsalam alikom wa ra7mat Allah wa barakatoh (Peace upon you)I’ve recently ran into problems with VS 2008. Summarized here:When you try to edit the project properties (specially C++ projects) you are faced with a little nice message saying “Exception from HRESULT: 0xF9F0F308”. Sometimes when you are editing a file (specially large ones), VS doesn’t recognize you’ve made changes (ie doesn’t display that ‘*’ in the files tabs) hence, when you save, nothing actually gets saved. For those 2 problems, a friend explained the problem and a work around (till they officially release a fix)…Open up a Visual Studio 2008 Command Prompt Run cd "C:\Program Files (x86)\Microsoft Visual Studio 9.0\Common7\IDE" Make a backup copy of devenv.exe in case something does not work right.
ie. copy devenv.exe devenv.exe.bak Run editbin /largeaddressaware:no devenv.exe Happy VSing… :)
