FDI in India

Why we don't need FDI in India ?

Whenever I hear about the word FDI the first thing that strikes in my mind is EAST INDIA COMPANY hope no one would have forget about that one . Do we need a foreign investment in our country India is an developing country very soon it would enter the super country list why do we still need a foreign investment in our nation to develop .

If FDI enters into our nation Indian economy will not be in hands of Indians , FDI will hold 51% of the shares that means no one can decide what they should do expect them self . They will decide the price of the product .

An example from the previous decade

When coke and Pepsi enters our nation there where some other Indian products like kalimark and bovonto. They both were in same price . Because of the tough competition our Indian products where eliminated now only foreign cool drink are available in market whatever the price they fix we have to buy now our economy control moves to foreign hands .

It doesn't meant we don't need foreign investment . Foreign investment is also required but we don't need it all sectors . India is an agriculture nation it should be in our control not in other countries .

Next world will not be in form of weapons it would be in form of economic.

Alternative power supply

Why can government use solar power and wind mills .instead of spending 1000 of crores to.a nuclear power station government can spend same amount of money to solar power supply .

A big draw back is there in using solar power it requires a large number of space . Tamilnadu government gives free of television mixers , fan , grinder so on instead of that why can tamilnadu government can solar panels to.each and very home.

1000 of technology are there . Sad thing is even the projects of the students are not implemented by government .I seen a project in my college a project about saving electricity in street light according to that project street lights will be working only during night time using sensors these kinds of technology can be implemented . Individual or group of solar panels can be used for street lights .

Government should think about all this new ideas or else its hard to survive .

Unrecognized escape sequence in C# SQL

I 've faced an problem in SQL server database connectivity from C# its all because my server name consist of  "\" ,C# read \ as n escape sequence to resolve this problem  use "@" symbol before the connectivity statement.

("Server=DIVI-PC\SQLEXPRESS;database=project")

Here is the problem there is "\" after the DIVI-PC C# reads its as an escape sequence so it is not possible to connect with sql  to Solve this problem add "@"

(@"Server=DIVI-PC\SQLEXPRESS;database=project")

Now it 'll work .

NOTE : Don't forget to add username and passwords

Suggestions are always welcome !!
