It indicates that the implementation of the
int __cdecl sumArray(int * const,int)
function is missing.

You seem to have declared the function sumarray(...) but forgot to implement it.

Hello,
I copied a large file from one disk(source) to another disk(destination). After this I made (manually or programmatically) some changes in the file on the source disk. Now, these changes should reflect in the file on the destination disk also. In order to achieve this, I copied the file again from source to destination. Since the file is a large one this method is not efficient. Because, for any minute change, I have to copy the entire thing.
Is there any way to copy only the updated portion from the file on the source disk to the file on the destination disk?
Hoping to get a reply soon.
Thanks in advance.
regards,
Jahfer V P.

When you are making changes to the file, make another file (changes-file) also, with your own file format:
Repeat (1) below for every change:
1- The size of data in four bytes (long int) then four bytes (long int) for offset into the file for the data, then the data. Write this into your "changes-file".
Then when you need to update the destination file, repeat (2) below until the end of the file.
2- Read the "changes-file", and correctly read the length of data, offset of data, and the data. Then open the destination file in update mode, move into it at the correct offset, and write out the data you read from the "changes-file".
Does that solve the problem?
this is this.

Dear khan++,
That doesn't solve my problem, because I am not the person going to update the file. More over, the file may get updated not only at its end but anywhere in it.
Any other idea?

Jahfer V P.

I don't get it.
The technique I gave can update the file anywhere in it, not just the end, that is why I asked for an offset field.
I hope someone else can help as I am about to logout for the day.
this is this.

Could any body provide me basic algorithms for Fading IN or Fading Out of the Image and other related EFFECT.
Thanks

I haven't done such a fade in filter but for a smooth
transition--one image fading to another--I'd guess you
just need to scale each pixel's R,G & B values in the
'old' image toward the R,G & B values of the corresponding
pixels in the new image.
e.g if you want to do a full fade from old image to identically
sized new image in 10 steps :
for ( each pixel position in the image(s) ){
<font color=#FBEDB5>__<font color=#000000>for (Step = 1; Step<=10; Step++){
<font color=#FBEDB5>____<font color=#000000>IntermediateR = OldR + (NewR-OldR)/10 * Step;
<font color=#FBEDB5>____<font color=#000000>IntermediateG = OldG + (NewG-OldG)/!0 * Step;
<font color=#FBEDB5>____<font color=#000000>IntermediateB = OldB + (NewB-OldB)/10 * Step;
<font color=#FBEDB5>__<font color=#000000>}
}
(Be sure to use signed types for the RGB values so that
the scaling will correctly handle the cases where R, G or B
in the old image are larger than the corresponding R, G or B
value in the new image.)
If you want to fade to (or from) a 'blank' screen just substitute
the constant 'blank' RGB values for the new (or old) image pixel
position RGB values as required.

STPI : Stands for Software Technology Park or India. AFAIK, there are more than 10 STPI in India. In which one are you working!
