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,


This is the function that opens the file :

// 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; 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. ...

How To Recognize Time Past
How do I make my program know that time is passing and interact with it? Currently I'm trying to use a method like this:
Imports System.Globalization
Private Sub CurrentTime_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CurrentTime.Tick
Dim date_info As DateTimeFormatInfo = _
ToolStripLabel1.Text = Now.ToString(date_info.ShortTimePattern)
End Sub

That sets the current time to ToolStripLabel1.Text it looks like: 10:25 PM. Then I made another timer, realizing I couldn't interact with Toolstriplabel1.text because the time contains " : and PM", and this timer does this:
Private Sub Timer2_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer2.Tick
TextBox48.Text = Val(ToolStripLabel1.Text)
End Sub

Basically it takes the value of toolstriplabel1 which would be "10" it gives a variable 1-12 in accordance with the current time. Then I have another timer that handles the main process, and in My.settings I have a variable:

So I was going to use My.settings.12hourspassed as a variable such as My.settings.12hourspassed = My.settings.12hourspassed + 1 - whenever the time (textbox48.text) goes to 12.
Private Sub Timer_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer.Tick
If Val(TextBox48.Text) = 12 Then My.settings.12hourspassed = My.settings.12hourspassed + 1
If Val(TextBox48.Text) = 12 Then TextBox48.Text = "1"
End Sub

The problem is that I cant do textbox48.text = "1" because another timer is making it the value of the current time.. So whenever textbox48.text = 12 it constantly does: My.settings.12hourspassed = My.settings.12hourspassed + 1...

I know that this method completely skips an hour and such.. accuracy isnt all that huge. Any way to tick off whenever 12 hours have passed? and if the program is turned off a way to compare the current date with the date the program turned off at to see how much time has passed while the program is off? ...

Get The Color Of The Top-left Pixel Of The Desktop Window?

P.S. Is there any alternatives for obtaining the desktop pixel colors? ...

Sorting Listbox Items Numerically In VB?
I need to sort the items in a visual basic listbox numerically, that is, I have a collection of numbers I would like to be sorted increasingly.

I tried to simply use the listbox's Sorted property, but found that it treated the numbers as if they were strings, that is, it would look at the first digit, then the second, etc. to determine the order. That meant that 13 would show before 5, for example.

I thought of dumping all the numbers into an array, soring the array, and then pushing them back to the listbox, but, honestly, I don't know how to go about the sorting. I figured the array would be useless, since the listbox already acts as a pseudo array. ...

Windows 8

Windows Store Not Allow Sign In From Local Account
I have Windows 8 installed on a local account and wish to sign in from my Microsoft Account but only as & when required not all of the time. Shawn's tutorial "How to Sign in with a Different Microsoft Account to the Store in Windows 8" covers the procedure which should apply.

Attempting this offers only the "Sign In" button however once clicked the spinning circle appears for a fleeting second before the pointer is returned to the button once more, further attempts loopback in the same manner.

I can only surmise that this is happening because I have undertaken a customised install using Kari's excellent tutorial "How to Relocate User Profiles to another Partition or Disk in Windows 8" where the User Profile concerned is "D:User" and not "C:UsersUser" this being my longstanding preference from previous Windows installs from XP to 7.

I have tried the mklink /j route to link both C:UsersUser and D:UsersUser with D:User but with no success.

Is there a registry key containing the profile path which is used by the store sign in which requires modifying to my customised path of D:User?? .....or is something else amiss?? ...

Windows 8 On Netbook - Metro Apps Won't Work?
it installs without a hitch, comes up, runs fine ... just don't try running any Metro apps because most of them won't work - the screen resolution I have is something like 1024 x 600 (fine for this device) but that's too small for most apps. The desktop is fine but virtually nothing else can be run outside that.

I like my little netbook but Windows 8 doesn't. I made an image of that drive becuase I'll be restoring that soon. ...

Audio Distortion Followed By Computer Freezing?
I have had this computer for about a year now and it recently started acting up. What happens is the audio begins to distort and than the computer freezes if I close something out. This only used to happen when a lot of stuff was running at once or a big game was player, Spore for example.

Recently it has been doing it more. Before if I skyped with youtube on while i played a game, you know big stuff, it would do this, but now if I have a paused youtube video or an ended youtube video on while I play minecraft it does the same thing. There is no error code or anything, I have to manually turn it off and on. ...

Applications :: Finding Alternative To IPhoto?
I am looking for an alternative to iPhoto for viewing and organizing photos. I need something that allows for tags like iPhoto does and preferably something with a full-screen mode for editing.

My main problem with iPhoto is that it gets bogged down when you have imported thousands of photos. And I hate having to import photos on external drives before I can view them.

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