Hi,

I tried My best to add ODBC System Data Source for Access (.accdb) Database using VB.NET. Searching from Google I tried many Functions but nothing worked.

Code I tried is :

VB

Sub createDSN()
        Const ODBC_ADD_SYS_DSN = 4 ' Add data source
        Dim dbpath As String = "C:\Jenit\Data\001.accdb"

        Dim ret As Integer, Driver As String, Attributes As String

        Driver = "Microsoft Access Driver (*.MDB,*.accdb)" & Chr(0)
        Attributes = "DSN=" & "Hello" & Chr(0)
        Attributes = Attributes & "Uid=Admin" & Chr(0) & "pwd=pwd" & Chr(0)
        Attributes = Attributes & "DBQ=" & dbpath & Chr(0) & Chr(0)

        ret = SQLConfigDataSource(0&, ODBC_ADD_SYS_DSN, Driver, Attributes) 'Error Here


        'ret is equal to 1 on success and 0 if there is an error
        If ret <> 1 Then
            MsgBox("DSN Creation Failed")
        Else
            MsgBox("Successful")
        End If

End Sub 'Main

Error is :

A call to PInvoke function 'j!j.Form1::SQLConfigDataSource' has unbalanced the stack. This is likely because the managed PInvoke signature does not match the unmanaged target signature. Check that the calling convention and parameters of the PInvoke signature match the target unmanaged signature.

Please Help.

A question first...Why are you even using a DSN?? All that is is a connection string in a text file. You get the same functionality by putting your connection string in your applications app.config file.

Jenitshah,

The method to access the database using "DSN" is quiet old method and not been used any more in the industry.

putting the connection string in the app.config file and using it to connect to the database is a commonly used method. please see the similar post http://www.codeproject.com/Questions/254402/How-To-Store-and-retrive-ConnectionString-from-app if you need further info

if you still have issue let me know
