Steel is a relatively cheap metal to sell and you would need a lot of it to get a large profit. The price of steel varies depending on the current market. Contacting a local scrap yard would be the best way to know the current rate.
What the meaning of cell pointers in Microsoft Excel?
A cell pointer in excel is just the cell where you point the cursor in which its row and column can be seen is called a cell pointer.
What is mean by text and binary files used in c?
A text file is a file containing human readable characters organized into records (lines) that are separated by the new-line character. The run-time library parses on this basis, and converts carriage-return/line-feed sequences to and from the new-line character as needed. (In a Windows/DOS environment.)
A binary file is a file containing any characters. There is no file based delimiting - all record distinctions are made by the program. (The exception to this is in the IBM (and other?) family of MainFrame computers where logical record sizes are declared in the DCB, and the file is not processed in stream mode.)
What kind of document is a text file that contains the webpage content?
Web pages obviously have links to other pages, but many types of documents support links to other pages. You can put them into many Microsoft applications for example. The links themselves are referred to as hyperlinks.
What is the INT86 function in C programming?
INT 86 Int86() is a C function that allows to call interrupts in the program. prototype in dos.h In and out register must be type of REGS. REGS is a built in UNION declaration in C. It is defined in the header file <DOS.h>
How do you display alphanumerics in C program?

What is a handle in Windows Programming?
A handle is a reference for the operating system. It does not have the semantics of a programming reference but what it does do is allow the system resources to know what you are referring to when it is passed in an API call. Usually, the HANDLE is wrapped in an instance of a class. CWnd is a good example, it contains an HWND which is a handle to a window. You can do this. CWnd *pWnd = CWnd::FromHandle(hWnd) Note: that CWnd::FromHandle(hWnd) is static and does not require an instance. It will pass you back the wrapper that the hWnd is wrapped by. Well not quite! If the handle is not actually wrapped by an object it will create one AND IT WILL ONLY BE TEMPORARY.So use it the once then throw it away. It can create the instance because the hWnd has enough information in its struct for windows to instantiate a CWnd object. It does not add it to the handle v object table, so it is only temporary. The HWND is in fact a kernel object and theres more ? HWND (CWnd and CWnd-derived classes) HDC (CDC and CDC-derived classes) HMENU (CMenu) HPEN (CGdiObject) HBRUSH (CGdiObject) HFONT (CGdiObject) HBITMAP (CGdiObject) HPALETTE (CGdiObject) HRGN (CGdiObject) HIMAGELIST (CImageList) SOCKET (CSocket) (Should have been HSOCKET?) + others. I am not sure if all of these would pass back a temporary object if required. ::GetDC(hWnd) will get you a hDC from an hWnd but it will be temporary, probably better to use the CDC claa. It may be a fundamental requirement for windows programming? For a proper explanation look up google with this "Inside MFC: Handle Maps and Temporary Objects"
What is the best way to merge partitions on your hard drive?
One of the safest ways is to purchase a software program, e.g. Partition Magic, which can do this without destroying any of the data that may be on the partitions.
Better way
The safest way is to backup all your data. format HD and repartition with fdisk. Then install your programs and restore the data.
Although there are many programs to partition HD without lose data, nobody will recommend use them without backup your data. And if you backup all your data why not format your HD and reinstall programs - that way all your programs will run faster. If you don't have the time to reinstall or the original programs discs, You still must backup all your critical data, and this exist in many places on your HD, not just in "My Documents" folder, like Outlook data. So be care and lot of luck.
---- In Linux: After MUCH frustration, digging, trial-and-error, I have answered my own question.
My problem, as you may recall, was that I could not delete or resize two "unallocated partitions on my hard drive. All the options (unmount, resize, delete, etc.) were grayed out. I could not unmount them because they were in use.
The answer was to download the GParted LIVE CD from: http://gparted.sourceforge.net.
I simply inserted the GParted LIVE CD, rebooted, and -- voila! -- I could move, resize, and delete all my partitions at will! IMHO, the GParted utility is much easier to use then Partition Magic, and best of all, it is FREE!
I hope this post can help others with a similar problem.

How do you create window with c?
It is not possible to create a window with C as the C language does not specify any standard libraries for doing graphical programming. It is possible to create a window with C and one of the many graphics libraries that have been written since C was created. For example, using the Gtk+ library: #include #include int main (int argc, char *argv[]) { GtkWidget *window; gtk_init (&argc, &argv); window = gtk_window_new (GTK_WINDOW_TOPLEVEL); gtk_widget_show_all (window); gtk_main (); }
prime a loop is that how mach time it executed either max time or minimum time
What is the minimum number of times a do- while loop is executed?
A do while loop is executed at least one time.
What is difference between for loop and while loop?
One first basic rule is that you should use the for loop when the number of iterations is known. For instance:
- The loop iterates over the elements of a collection.
- The loop iterates over a range of values which is known in advance at execution time.
- The object provides a way to iterate over its elements with a for statements (e.g files).
The while loop is the more general one because its loop condition is more flexible and can be more complicated than that of a for loop. The condition of a for loop is always the same and implicit in the construction. A for loop stops if there are no more elements in the collection to treat. For simple traversals or iterations over index ranges it is a good advice to use the for statement because it handles the iteration variable for you, so it is more secure than while where you have to handle the end of the iteration and the change of the iteration variable by yourself.
The while loop can take every boolean expression as condition and permits therefore more complex end conditions. It is also the better choice if the iteration variable does not change evently by the same step or if there are more than one iteration variable. Even if you can handle more than one iteration variable in a for statement, the collections from which to choose the values must have the same number of elements.
Note: In C 'for' and 'while' can be easily replaced by each other:
while (exp) stmt
for (;exp;) stmt
for (exp1;exp2;exp3) stmt
{ exp1; while (exp2) { stmt exp3}}
How do you make a window full screen?
Well, if we're talking about Windows you should make the window as big as the display resolution, and use ITaskbarList2::MarkFullscreenWindow to make sure the taskbar has lower z-order than your window.
What is the while loop in C programming?
"while" is an entry controlled loop statement i.e the condition is evaluated first and if it is true the body of the loop is evaluated.This process is repeated until the test condition is false;then the control is transfered out of the loop.
The general form of while is as following
syntax:
while (<condition>)
{
<statements>;
}
Is the cost of creating a process or a thread higher?
Raj, Processes are ALWAYS more expensive than threads. Threads are considered a component of a process. That is...a process can consist of several threads of execution. The exact "cost" in memory, or allocation of time depends on the operating system, but a thread is frequently 10% or less than the "cost" of a process.
AnswerWell this answer seems to be like what do you think of whether putting a new task force to do same task is Costly or using the same task force to do it for yourself when having one factory for processing in a pretty cooperative way, the answer is as usual putting same task force and that is why processes are heavy and threads are light. Because each time allocatin a new process means to launch a new set of each resources needed for its execution while Thread share some props in common that doesn't need to be reallocated and those behave like shared buffers or resources.

How do you make a batch file to delete all files and folders in a particular folder?
The command is as follows :
del c:\[directory you want to delete] /s
This would need to be in a text file created in notepad, and saved as a .bat file. Or you could type EDIT from the command line to bring up the old DOS editor.
Improving answer: Step 1: Open up Notepad Step 2: Type the following code in: @echo off deltree [Your hard drive, usually C:]\[Directory you want to delete /s for quietly Step 3: Save as "whateveryouwantwithoutquotes.bat"
How do you convert HTML images into JPEG images?
haller?? think it logically!..^_^
right click in the images in the HTML then save in your computer as jpeg actually if you save it , automatically it will save as jpeg or gif.
HTML is for creating a website if you want to put your image in your website there have a code like this
background="/images/image_name.gif"> like that ok??-louieann.1990@yahoo.com
How do you run jar file on computer?
you can play the jar files by transfer it in to nokia mobile phones
examples of internal noise.thermal noise,short noise,i/f noise
How do you run daemon process?
(link moved to link section)
AnswerIn Solaris, you need to disconnect your program from your "terminal" ( scripts generally inherit the stdin, stdout, and stderr of your shell when you execute them ). For a shell program you can execute "nohup $program < /dev/null > /dev/null 2>&1 &". Or the shell program can redirect its own stdin, stdout, and stderr -- then you can execute "nohup $program &".What is the different between loop and do while loop?
no difference in logic in both of them you put the key to enter :while( ....),for(;....;)
but infor loop you have option to initialize value and make operation on it
for(int i=0;...;i++){} same int i=0; while(..){ i++;}
When you double click your c drive it says application cannot be run in Win32 mode?
I also had this problem few dayz before and it just made me mad, i was felt into that situation that i even cannot format ma windows so, finally i researched upon it and found the solution :-
1. Go to your first drive for example c:/ and delete the hiden file autorun.inf also delete from recycle bin
2. Then create a folder name autorun.inf after delete first one as soon as possible
3. do the same thing with all of your drives
4. Log off ur PC your PC
