Re: SQLite database table to 2 dimensional string array.

Looks good.

I have some suggestions which are sincerely intended as to be encouraging.

Firstly I would always use the using statement rather than manually calling Dispose eg:

            using (SqlDataReader reader = cmd.ExecuteReader())
            {
                //Somde code here
            }

For a few reasons - firstly you won't forget to call Dispose. Secondly it gives nicely structered indentation making it easier on the eye to see what is happening and thirdly because it is the way most developers do it so its a kind of unwritten standard.

I would also be mindful of the S in SOLID. That is single responsibility principle. This method does a lot. I would split it up a bit more. In Visual Studio a great thing to play with is highlighting a block of code that looks like it could be a seperate method or class and then right click and Refactor - try extracting to method - VS will figure out the parameters and does all the work for you.

Smaller, more cohesive methods are easier to maintain, test and debug.

And finanlly in C# we say methods not functions - sorry if that one is too picky!

Re: How to sum to specific count of rows in Datagridview

Can you not just hard code this:

Dim x As Decimal = 0

x += Convert.ToDecimal(Table1DataGridView.Rows(0).Cells(1).Value)
x += Convert.ToDecimal(Table1DataGridView.Rows(1).Cells(1).Value)
x += Convert.ToDecimal(Table1DataGridView.Rows(3).Cells(1).Value)

Where Cells(1) is the appropriate column?

Blue Pill or Red Pill

I love optical illusions and they normally work on me but in the following one you are supposed to be able to see a red pill and a blue pill when in fact they are both grey. I see them both as grey though - does anyone else see red and blue?

This is one of my all time favorites.

If you want some fun, print this one out twice. Cut out square A and then slide it from A to B on the other printout. You see it amazingly change colour as you slide it!

Edit Post Bug

Is there a bug when editing a post?

To reproduce follow these steps.

a) Reply to post

b) Edit to correct a typo maybe

c) Save

d) Edit again as you spotted another typo - the editable text then does not load the latest correction.

I am using IE 11. Not sure if it happens all the time but I have noticed it a few times. The only way to be sure would be to test more thoroughly but that would mean a thread with lots of test posts which I'm sure you don't want.

Re: Where did i put the "Employee already Exist? Help me.

You don't want all that code inside a button click event handler.

Break your code up into discrete classes and methods of specific functionality. It will make everything much easier.

Your button click code should be very simple like below - note this is pseudo code (http://en.wikipedia.org/wiki/Pseudocode)

If FormIsValid() Then
    If UserExists() Then
        ShowUserExistsMessage()
    Else
        SavePicture()
        SaveRecord()
        ClearForm()
    End If
Else
    ShowInvalidFormMessage()
End If

So you can write a Function which returns a bool if a user exists. Try and think like this rather than having one massive block of code which does everything. It will be easier, more fun, easier to fix and add to later and easier for other people to understand and easier to reuse code too.

Re: just a question

void is a return type. In programming languages methods or functions may return something. What type of data they return is usually specified in the method signature. If they don't return anything then void can be used to signify this.

C++ types can easily be found on many website such as http://www.tutorialspoint.com/cplusplus/cpp_data_types.htm
