The Role of Private Equity in Starting a Business.

October 13, 2012 ~ Deepesh Singh

This market is for the trading of company stocks and derivatives by public thus generating money. An investor of equity capital is like shareholder in the company. He is like a partner to the SME. No compulsion of amount refund invested in share by the investor. Not any compulsion to pay interest on equity like it is done in debt market. If a company earns profit then the investor earns profit too. It is the most effective way to raise capital. Since the owner has no worry to earn profit to give interest like debt market. It encourages the entrepreneurship and innovation in a positive and big way.
There are two important body of private equity. Those are:
Venture capital
Venture capital consists of funds, equity or conditional loan in order to promote unlisted, high-risk or high-tech firms or small business, driven by technically or professionally qualified persons. Such funds are so blind that one can‟t expect the return. The investors invest money via a channel.
Angel Investors
Angel finances are those types of finance where investors are generally family members or friends. They may provide money at the time of start-up or in between for the growth of the firm. They are direct investment.
Angel and venture capitalists invest their money very intelligently and selectively but without stepping into a controlling or operating role. They don‟t invest blindly to any small businesses or firms. They use to choose only those firms which have higher potential growth and having scope in future.

Back Button Problem in ASP.NET After Logout

April 4, 2012 ~ Deepesh Singh

I was facing a problem during one of my project. Actually, I was developing an E-Commerce site, in which I need to give login and logout button. I did login part easily and logout also. But problem arisen, when I pushed back button. Oh! God! Even after logout, it creates a session without login. How? I put all code behind ‘Logout’ button. But still I was facing the problem. We saw many codes, tried a lot of way to logout but still back button is not disabled.
One easy way to solve this problem is applying javascript. It would not allow a person to go back to that page. But, is it a feasible solution? NO! One would like to go back, even after logout to see something. This javascript would disable to come back. So, that is not a proper solution.
So, here I am writing the proper code, which we finally found out and happy news is that, “It really works!”. So just follow this code.
If you applying a MasterPage, then copy these codes to its page load, or copy to that page’s load, which comes after login page or comes before logout page.

And on logout button click, write these codes.

So, if you still getting some kind of problem, please leave comment.
