I am using an Access database and vb.net 2010. I have created a table in the database with columns for title, datein, dateout and roomnymber. In vb.net 2010 I made a distinguished title = combobox, datein and dateout = DateTimePicker. When I click on F5, an error occurs: INSERT INTO Syntax Error in statement. [Code]
View 1 RepliesI've linked the two using the standard data sourcing method and I now need to use the data that is read in to it on another form. The idea of this is that I'm creating a wage calculator and the employees are stored in a database and can be viewed on a vb form, however, I now need to use the data of their pay/hr to be used on another form to calculate the wage.I have tried to declare a public variable across the two separate forms, and on the button that takes you to the other to set this variable as the contents of the text box which is displaying the pay/hr using the following
Public Class ManageUsers
Public HrlyRate As Decimal 'Declaring global variable to use between forms
'Some other code in between relating to rest of the stuff on the form
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
RatePerHourTextBox.Text = HrlyRate 'Saving private variable to global variable
Calculation.Show()
End Sub
End Class
Then on the other form I have used this code to do the calculation:
Public Class Calculation
Private Sub calculation_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
End Sub

I have to store a image file into my Access database.
For that i've used 'OLE Object' datatype for my field. When i convert the image into byte array and tried to insert it, i got an error saying "Syntax error in INSERT INTO statement"

View 12 RepliesI've always used this approach while implementing data layer DLL for web application:
1) put datasets into the dll project
2) use a helper class with a method like this:
public shared sub settCnnStr(strconnhere as string)
My.Settings.Item("connectionString") = strconnhere
end sub
3) when I need to use the dll I call a method like this (usually into global.asax):
xxxxxxx.helper.setCnnStr("yyyyyyyyyyyyyy")
This method always worked for me nicely but I'd like to know if this method could have serious drawback or if there's a better solution.

Is there a way that i can get the data source to update itself when the form loads?
