Question How to take a value form one form to another from

[tashiduks]

Hi,

I have a Two Forms Created under one Class Library. My Project Looks Like that:

MyProjectClass (class Library)
- frmMain.vb
- frmLogin.vb
- Class1.vb

Now when i run first it loads the "frmLogin". After typing valid User Name and Password, it opens "frmMain". Till here its fine.

Now the problem is: when frmMain opens, the txtUserName.text value of frmLogin should display in frmMain Statusbar which is not happening. I have following Code:

frmLogin

Private Sub btnOK_Click(sender As Object, e As System.EventArgs) Handles btnOK.Click
dim fMain as new frmMain
 If Me.txtUserName.Text.Trim = "admin" And Me.txtPassword.Text.Trim = "123" Then
                Me.Hide()
                fMain.showdialog()
               me.txtUserName.text = fMain.usernamestatusbar.text 
else
           MessageBox.Show("Invalid User Name or Password! Please try again. ", "Login Failed",  MessageBoxButtons.OK, MessageBoxIcon.Error)
                Me.txtUserName.Focus()
                Me.txtPassword.Text = ""
End If
End Sub

Can anyone tell me why its not working? I am using VB.NET 2010 (VB Language)

Thanks

That code is poorly constructed I'm afraid. It should be completely reconstructed.

For one thing, you're never passing any data to frmMain. You have code to get data from it, but that code is executed after frmMain closes.
