[RESOLVED] My.Application.Info.DirectoryPath

What am I doing wrong ?

Code:

---

This is working
dbSource = "Data Source = C:\test\AddressBook.mdb;Jet OLEDB:Database Password=123;"

This is not
dbSource = "Data Source= (My.Application.Info.DirectoryPath & "\AddressBook.mdb;Jet OLEDB:Database Password=123;")

---

What ever I chang it is not working .
The file is Adressbook.mdb
Password = 123

and the file is here

My.Application.Info.DirectoryPath

either you mistyped it or you are get an error at design time because your quote don't match...

try something like this
dbSource = string.format("Data Source= ({0}\AddressBook.mdb;Jet OLEDB:Database Password=123;",My.Application.Info.DirectoryPath)

or you could use IO.Path.combine(My.Application.Info.DirectoryPath,"\AddressBook.mdb") to create the full path first

Thanks , but no result

not sure but think you missed a closing quote

Code:

---

dbSource = "Data Source= (My.Application.Info.DirectoryPath & "\AddressBook.mdb;Jet OLEDB:Database Password=123;")"

---

try that

Nope ,

Here is the code that i have found , maybe that explainse my problem .
To open the file .

Code:

---

  Dim con As New OleDb.OleDbConnection
        Dim dbProvider As String
        Dim dbSource As String
        Dim ds As New DataSet
        Dim da As OleDb.OleDbDataAdapter
        Dim Sql As String


        Try
            dbProvider = "PROVIDER=Microsoft.Jet.OLEDB.4.0;"

          ''This is working
            ''dbSource = "Data Source = C:\test\AddressBook.mdb;Jet OLEDB:Database Password=123;"


          '' This is not
            dbSource = "Data Source = (My.Application.Info.DirectoryPath & "\AddressBook.mdb;Jet OLEDB:Database Password=123;")

         
            con.ConnectionString = dbProvider & dbSource
            con.Open()

            Sql = "SELECT * FROM tblContacts"
            da = New OleDb.OleDbDataAdapter(Sql, con)
            da.Fill(ds, "AddressBook")


            con.Close()


         
            TextBox1.Text = ds.Tables("AddressBook").Rows(0).Item(3)
         
         


        Catch ex As Exception

        End Try

not sure how that code even compiles.... you are missing a quote.

Did you try my suggestion? it doesnt look like you made the change based on the code you just posted. I understand our problem.

You are missing a quote

try what I suggested please

billboy , I tried that


But then i get a error on Adressbook , database en password they are not declared

I think You are correct there is missing a qoute or something

me shakes his head and points to post #2

Kebo ,

I tried that but it is not working.

I don't understand what You mean by that.

The String.Format method will create a string for you from text and variables. In the following line....

Code:

---

dbSource = string.format("Data Source= ({0}\AddressBook.mdb;Jet OLEDBatabase Password=123;",My.Application.Info.DirectoryPath)

---

My.Application.Info.DirectoryPath is a variable that replaces the {0} in the beginning of the string

Code:

---

dim s as string = "vb.net"
dim s2 as string = String.Format("{0} is ok",s)

will result in
s2 = "vb.net is ok"

---

Did you try it?

Please dont say things like "I tried it it dosnt work"
post what you tried, often times you may think you tried it correctly but made a mistake or were confused about something(trust me being new myself i have done that a thousand times)
so post your new code and we can see if mistakes were made

did you try kebos suggestion in post#2, that is a cleaner way of doing what you want and less prone to errors with quotes and such

again post the code you tried and the erro you get and where the error occurs

Oke sorry,

Here is my latest try

Code:

---

Dim con As New OleDb.OleDbConnection
        Dim dbProvider As String
        Dim dbSource As String
        Dim ds As New DataSet
        Dim da As OleDb.OleDbDataAdapter
        Dim Sql As String

        Dim s As String = "My.Application.Info.DirectoryPath"
        Dim s2 As String = String.Format("{0}\AddressBook.mdb;Jet OLEDBatabase Password=123;", s)

        dbProvider = "PROVIDER=Microsoft.Jet.OLEDB.4.0;"
        dbSource = String.Format("Data Source= ({0}\AddressBook.mdb;Jet OLEDBatabase Password=123;", My.Application.Info.DirectoryPath)

        con.ConnectionString = dbProvider & dbSource
        con.Open()

        Sql = "SELECT * FROM tblContacts"
        da = New OleDb.OleDbDataAdapter(Sql, con)
        da.Fill(ds, "AddressBook")
        con.Close()

        TextBox1.Text = ds.Tables("AddressBook").Rows(0).Item(3)

I get a error now

Code:

---

Could not find installable ISAM file.

---

In a connection string you use |DataDirectory| to represent the program folder.

Code:

---

Dim connectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=|DataDirectory|\AddressBook.mdb;Jet OLEDB:Database Password=123"

---

As there is no 64-bit version of the Jet OLE DB provider, make sure that your project targets the x86 platform or it will not work on 64-bit systems.

This is working , thanks You all for your help

Code:

---

dbSource = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=|DataDirectory|\AddressBook.mdb;Jet OLEDB:Database Password=123"

great please rate and mark your thread as resolved :)
