Project BigResource

Since 2005, our team is working 24/7/365 to maintain one of the World's largest resource center for webmasters and programmers. The project comprises a directory of 50,000 Scripts & Tutorials relating a wide range of programming languages from PHP, .NET, ASP and Java to emerging Android & iOS development.

We also maintain an index of over 3 million questions/answers posted over internet relating aforementioned technologies. To learn more about Tracker, click here.

It took us 10 years of hard work to build an index of 3 million plus qualified Q&As by humans, not the bots. Just Crawling and building a database of messages is not an art. The success of this unique project lies in the human editing of these messages by professionals for content validity and definitive solution to various problems to stay focused on the issue & saving time. Compare and see the difference between an original post on a forum and the same edited message added to our index here. No unanswered posts, salutations, lengthy code lines, images, avatars, attachments, closing remarks, reference URLs, signatures etc., just the core issues and solutions to them.

As of June 2014 stats, 50,000 unique visitors/webmasters visit us every day to get benefited from this index. We are working hard and striving harder to provide programmers an unmatchable resource index to their unanswered questions.

C++ :: Open File And Read In Rows To String Vector And Return Vector
I have a cpp app that reads in a number of files and writes revised output. The app doesn't seem to be able to open a file with a ' in the file name, such as,

N,N'-dimethylethylenediamine.mol

This is the function that opens the file :

Code:
// opens mol file, reads in rows to string vector and returns vector
vector<string> get_mol_file(string& filePath) {
vector<string> mol_file;
string new_mol_line;
// create an input stream and open the mol file
ifstream read_mol_input;
read_mol_input.open( filePath.c_str() );

The path to the file is passed as a cpp string and the c version is used to open the file. Do I need to handle this as a special case? It is possible that there could be " as well, parenthesis, etc. ...

Editing Refreshable Data Tables From Web
I have multiple data tables that are linked to a site. My issue is that there are breaks in the data every 15 cells with a row that shows the column categories. I locked my top row so I don't need the recurring column categories at all, but when I delete them and refresh the data they reappear.

How to delete these rows? Could I possibly run a macro that deletes the rows upon hitting refresh? Or is there a simpler way? ...

Calculate Percentage Of Individual Months Between 2 Dates And Populate Different Cells With Results
I want to display the percentage of occupancy for each month for condo rentals.

I have columns with dates that represent bookings throughout the year. check in and check out dates to be more precise. (A1 and B1 for example) and I have columns with months Jan, Feb, etc. (C1, D1, etc. for example)

The problem I run in to is that I can calculate the number of days between the dates and the fraction of the year (*12 to get a monthly value, but I fail to understand how I can break that up so that I can populate each month with a correct percentage of the total term.

E.g. A1=1-jan-2014 and B1=20-jan-2014 is an easy one because it only covers 1 month:
formula: =(YEARFRAC(A1,B1,3))*12 gives me 62,47% which I could just use as is for that month.

So far so good, but when the period covers more than one month or when the months overlaps, I don't know how to break the outcome up into the appropriate months to display the correct percentage for each month in its own column.

e.g. A1=1-jan-2014 and B1=20-Mar-2014 gives me a result of 253% with the same formula.
100% for November, 100% for December and 63% for January, which I could somehow formulate to break up over different Months.

But then it gets more tricky. What if the booking starts on a day other than the 1st of the Month?

e.g. A1=5-jan-2014 and B1=20-Mar-2014
The result of the formula (243%) is correct, but isn't sufficient to put the correct percentages for each month in their respective column.

What formula(s) should I use to break down the percentages to match the correct fraction of each individual month?

Lightroom :: Images Are Not In Order In The Import Dialogue Box?

I've seen a lot of recommendations for Picasa, but I can't use that 'cause I'm on a PPC. ...
