View 2 RepliesI have a form where a number of textboxes are programmatically created within a flowLayoutPanel and named by adding together 2 strings.
With the click of another button i hope to have all the values entered into these text boxes stored in a text file. However, i cant seem to find a way to add strings together to allow me to retrieve the values entered within the text boxes created.
Below is the code i have so far: BTW FLP is my flow layout panel and c is my calculated nmber of textboxes that are created.
Private Sub createTB(ByVal c As Integer)
Dim x1 As Integer = 1
Dim y As Integer = 2

I recently learned how to send the contents of a vb textbox to a flash textbox which is in an swf embedded on my vb form using a vb button to trigger...

AxShockwaveFlash1.LoadMovie(0, "C:sample.swf")

I have just learned MySQL in VB.NET, but I am having a complication..When I grab a SELECT Query, I want to get - lets say the 'username' column in each row it receives. How would I do that?
MySQL.CommandText = "SELECT * FROM online"
MySQL.ExecuteNonQuery()
Label1.Text = 'usernamehere'
myCommand.CommandText = "SELECT 'USED' FROM `KEYS` WHERE `KEYS`.`KEY` = '" + TextBox1.Text + "'"
Dim myReader As MySqlDataReader
myReader = myCommand.ExecuteReader
While (myReader.Read())
MessageBox.Show(myReader.GetString(0))
End While
The returning string is "USED". But that is wrong: it should be returning integer 0 instead. Why is that? I changed the MessageBox line to MessageBox.Show(myReader.GetInt16(0)) but now it sends me an error telling me that the input string is not in the right format..
I learned about this query 2 days ago:-
SELECT SUM(DTotal) AS Monthly FROM bdailytotal
but how I'm going to view the total value of the summation? I had been searching for this but most of the answers I get is for PHP. Can someone show me how to assign that total value to a variable in VB.NET?
Or teach me how to assign that total value to another table.

View 2 RepliesI'm using VB.net to write a MYSQL application and one feature I need to add is the ability to add a column for each week that my employees worked. For example I want the first column to be called "W1" and the next one to be "W2" and so on, right up to "W52". How would I add a column to my table and have it's name add 1 to its current value? If there wasn't any letters in the name it would be easy but I need it to have the "W" in the title as well to avoid confusion. to add the column I have this:
Alter Table Manager ADD W1 MediumINT;
I just need the part that adds an INTEGER to a VARCHAR datatype if possible... Maybe there should be some sort of data type conversion involved? Just to explain further, the black bar at the very top are the date stamps for each week, I would like to have this included in the datagridview if possible but it is not required. Under each week column the employees will be entering the percents they worked (example: 20%, or 0.20 is one day of work) I know this is an odd way of doing things but its mandatory... and i was wondering if it were possible to automate the creation of these columns rather than me having to manually enter them.
the only way i could get a VB.Net program to insert a timestamp into a mysql db was using Now() in the VB and putting the column as Var Char in the Mysql DB. Have i royally screwed myself or can i still pull this back in PHP and manipulate the data, ie select * from test where date between...etc.How does mysql interpret a var char column in terms of dates/times?
