MDI Application Help

[1druid1]

Hi All

I have an Application with 2 forms

Form 1 = FrmWindow this is an MdiParent Form
Form 2 = FrmInput this is an MdiChild Form

On Form 1 I have a Menu thats says New Input the onclick event looks as follows.

Dim ChildForm As Form
ChildForm = My.Forms.FrmInput
ChildForm.MdiParent = Me
ChildForm.Show()

This works and opens the FrmInput as a child of FrmWindow.

On the form FrmInput I have two Textbox Controls and 2 Button Controls

Textbox 1 = TxtName
Textbox 2 = TxtEmail
Button 1 = BtnSave
Button 2 = BtnExit

On the On Click event of BtnSave I have

 SaveInformation()

The Public Sub for SaveInformation Looks like this.

Public Sub SaveInformation()
        Dim con As New SqlClient.SqlConnection()
        Dim com As New SqlClient.SqlCommand
        con.ConnectionString = SQLConnection()
        con.Open()
        com.Connection = con
        com.CommandText = "INSERT INTO TblInformation(Name,Email_Address) VALUES(@Name,@Email_Address)"
        com.Parameters.AddWithValue("@Name", My.Forms.FrmInput.TxtName.Text)
        com.Parameters.AddWithValue("@Email_Address", My.Forms.FrmInput.TxtEmail.Text)
        com.ExecuteNonQuery()
        con.Dispose()
        com.Dispose()
    End Sub

So when you click the save button it inserts a new record into the table TblInformation on my SQL database, everything works great. Now my problem is I want to be able to open multiple instances of the form FrmInput at the same time.

So I changed the New Input button to the following

Dim ChildForm As Form
Dim ChildInstance As New FrmInput
        ChildForm = ChildInstance
        ChildForm.MdiParent = Me
        ChildForm.Show()

This works and I can now open up mutiple instances of the form FrmInput, what I cant figure out is how to save the information on a particular instance.

Any and all help is apprecited.

Where are you calling the save routine from?

Hi DataMiser

I am calling the save routine from a Module I have created specifically for Data Functions

The code can be in a module or class but should be called from the instance of the form in question.
