I recently bought a hard disk and had formatted it on my friends system. The installation had no problems and I copied some software in that. But later I found that I could not read some of the files and without my knowing my friend formatted the disk. Now I have lost some important data and need to get back that in any case. Please do suggest some good tools which can help me get them back without much hassle.

I am debugging with gdb a huge program on HP-UX. It has a very strange behaviour and I could not identify the cause. Have a look at this for example:
(gdb) c
Continuing.

Breakpoint 2, CExtract::extractDAT (this=0x80000001007bb9d8, user=@0x80000001004d4670) at Extract.cpp:1761

(gdb)

I'm printing the address of meas before calling meas.getSumMethodName. After stepping inside the method, gdb prints the value of "this". Shouldn't "this" inside CMeasurement::getSumMethodName have the same value as &meas?
If yes, any idea why it doesn't? ]]> C++ putagunta http://www.daniweb.com/forums/thread124530.html Swap an array... http://www.daniweb.com/forums/thread124528.html Fri, 16 May 2008 10:13:01 GMT hi guys, it's been a while since i used c for anything so here goes a question tha may seem silly.


I have 2 variable length arrays....

  1.  
  2. int main()
  3. {
  4.         int n = 5;
  5.         int m = 6;
  6.  
  7.         int before[n][m];
  8.         int after[n][m];
  9.         array_function( 5, 6, before, after );
  10. }
  11.  
  12. void array_function(int rows, int cols, float after[rows][cols] , float before[rows][cols])
  13. {
  14.         //for some iterations        
  15.         for(;;)
  16.         {
  17.  
  18.                 //for all the elements int the array
  19.                 for (i=1; i<rows; i++)
  20.                         for(j=1; j<cols; j++)
  21.                                 after[i][j] = 4 * before[i][j]
  22.  
  23.                 //afterwards prepare for the next iteration [1]
  24.                 for (i=1; i<rows; i++)
  25.                         for(j=1; j<cols; j++)
  26.                                 before[i][j]=after[i][j];
  27.         }
  28. }
  29.  

...What i want to do is find a way to swap the pointers to the arrays. So that i can get rid of the last loop.
I figured that since i only need to calculate "after" based on "before" and then make "after"->"before" and recalculate "after".
It would save a lot of time if i just swapped the 2 pointers.

i tried the following but with no luck:

  1. //define function like this:
  2. void array_function(int rows, int cols, float &after[rows][cols] , float &before[rows][cols])
  3.  
  4. //call it like this:
  5. array_function( 5, 6, &before, &after );

Hello Daniweb Community,

I was just pondering through thoughts as one does, when I couldnt answer my own question. How do you force adverts onto a page.

The scenerio is, I will have people uploading there sites to my site, as free hosting and free subdomain name. But, as it is all free for them, I wish to include advertisements.

Companies like Piczo force an advertisement at the top of the page.

Can anyone tell me how this is done.

Thank you,

I'm having troubles with my JComboBox calculations. For example, if the strings in my JComboBox were String[] name = { "John", "Tom" }; And Tom was assigned 15% to his name. How can I have the cases in my action performed reach out to a calculation class to perform the calculation. What I want to do is have a total of the percent and amount added in a JTextfield to display in another JTextField. So basically the user is selecting a person, which has a certain percent assigned to the name depending on the person. Then the % is multiplied by a number from another textfield. The part I'm trying to figure out is how to display the total in another JTextfield depending on the person selected. If they pick case 0, it will only show John's amount in the totalField or if they pick Tom, it will only show Tom's amount in the totalField. What is the best way I can do this. I know how to do the calculations, it's the displaying part that I'm finding difficult. I left out alot of stuff, I'm just using this as an example. Thanks for hearing me out.
