Hi, I need to inherit my Form2 to Form3, when i use 'Inherits Form2' my form3 doesnt show up and I get this error message and I cannot view my Form3 design at all! Warning 1 The designer could not be shown for this file because none of the classes within it can be designed. The designer inspected the following classes in the file: Form3 --- The base class 'WindowsApplication1.Form2' could not be loaded. Ensure the assembly has been referenced and that all projects have been built. 0 0 All i want to do is use some text out of a textbox in form2 and display it in a label on form3 Many thanks, Brad

How can I set my program to only download if a newer version is available? My program right now is set to download a file from my site every time it opens but I dont want it to do that. I would like to only download the file if the time and data has changed in the FTP?

Thank you so much!!! I cant believe it was something that simple!!! Cheers again!

Hi, I am coding a login which involoves database verification. For extra security I added a new column to my database and added the extra code accordingly and I am getting this exception..

Source="Microsoft JET Database Engine" Here is the source for my project: Imports System.Data Imports System.Data.OleDb Public Class Form1 Dim mypath = "C:\Temp\mydb.mdb" Dim mypassword = "" Dim conn As New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & mypath & ";Jet OLEDB:Database Password=abc123" & mypassword) Dim cmd As OleDbCommand Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim sql = "SELECT UserID ,PassID, HardwareID FROM MYTAB WHERE USERID='" & TextBox1.Text & "' PASSID='" & TextBox2.Text & "' AND HardwareID='" & TextBox3.Text cmd = New OleDbCommand(sql, conn) conn.Open() Dim dr As OleDbDataReader = cmd.ExecuteReader Try If dr.Read = False Then MessageBox.Show("Authentication failed...") Else MessageBox.Show("Login successfully...") End If Catch ex As Exception MsgBox(ex.Message) End Try conn.Close() End SubI am completly stumped and dont understand what I have done wrong?

Hi, I am creating a login for a project at college and I really do have no clue where to start. My brief is that I need to access a database for login purposes and set groups for permisions to access different areas in my program. I looked at this source http://www.codeproject.com/vb/net/Login\_Control.asp but when opening I got errors so i couldnt see the structure of the code. Any links etc would be really appreciated. Thanks.

My.Computer.FileSystem.WriteAllText("C:\filename.txt", TextBox1.Text, True) That is how I have done it! Thanks for the help Christian!
