Hi

I created a code which reads data from user, processes it and write it back in to a file in .csv format so that user can see it in excel.
Although the program is running fine from the tc for any set of data, the exe file when i use directly is not able to write in some of the inputs.
Kinsly suggest a solution for this as i have to post the exe file and not the code to the user.

The program gets the activity codes, corresponding FTPs and number of working days.
It then calculates and print the corresponding per day hours in the excel sheet "ILC_code.csv".
It also adds information about the FTP and the hours difference occured due to some approximation.
The difference limit in this program has been set to a max of .1 hr per month.

>>program is running fine from the tc
I guess that means Turbo C compiler ?

Sounds like the csv file is not where you think it is. Check to see that it is located in the same directory as the *.exe file. If not, then did your program specify the full path to the file in the open statement ? [edit]see line 535 of the code you posted[/edit]

No.. i have not mentioned any PATH. also for some of the data enteries its working fine and creating the csv file. but for some its not. I thought there is some bufferstream problem.
but i was not able to solve the problem.
I have posted the code above.

I don't know what your code really does,
I just check the language semantics.

ilc *ob;	
ob=get_activities(ob);

check the codding of get_activities(..), it returns pointer to array of object of type ilc
but within the function get_activities (...). line number 300.

delete [] ob;

so according to my knowledge in some cases your code executes and in some it doesn't well, if it runs on Turbo C++ compiler, I suggest you must change your compiler, use VS 2005 atleast.

Is there a difference between the data that works and the data that doesn't work?

I got it to compile with VC++ 2008 Express. Please post the entries that work ok and an example of the entries that do not work.

I don't know what your code really does,

ilc *ob;	
ob=get_activities(ob);

check the codding of get_activities(..), it returns pointer to array of object of type ilc
but within the function get_activities (...). line number 300.

delete [] ob;

and you call delete[] ob in main () as well.

so in some cases your code executes and in some it doesn't well, if it runs on Turbo C++ compiler, I suggest you must change your compiler, use VS 2005 atleast.

thnx a lot. but the problem is happening at the level of writing to file the last step. its calculating fine. and and that to not for all the data. so really its confusing.
and also only the xe is giving this problem not when i'm directly running frm code.

>>its calculating fine
Not with the bug Laiq found. The program is attempting to use an uninitialized variable which can cause any number of program errors.

ilc *ob = NULL;	
ob=get_activities(ob);

[edit]You're right -- after looking at get_activities() the above really isn't a problem. But you should initialize ob to NULL anyway.

ilc * get_activities(ilc * ob)
{
	do
	{
		cout<<"\n\n Enter No. of activities : ";
		cin>>::noa;

		ob = new ilc[noa];

Why is ob even a parmeter to that funciton ? You might as well just make it a local variable.

thnx.. ya it might do that.,.. i just changed and again made the exe but its again throwing same problem. this is the copied image from command prompt (insde /* */) as below:

It stops here. i don't know why??

There is a definite problem in your program some place because the program crashes at the end. After I press any key to continue it crashes.
