[RESOLVED] Using Constructor Event Creates Errors...

I created an even on a form called Sub New so I can handle some events and close the window down if there is an error.

Upon doing that, I came across 3 errors that I don't know how to fix.

vb.net Code:

Me.Hide()
 
        frmEmail.SetReportDate = #1/23/2012#
        frmEmail.Show()
        frmEmail.Dispose()
 
        Me.Show()

I get 3 errors, on lines 3, 4 and 5

Reference to a non-shared member requires an object reference

How can I fix this? Note: ShowDialog really isn't necessary I could just use .Show. I want to use ShowDialog because the line under those 3 shows the current form.


Found the problem (I had private sub new) but now a new problem...
How do I pass the date to the form?

In case it's relavent, my code for sub new on frmEmail.

vb.net Code:

Public Sub New()
        ' This call is required by the designer.
        InitializeComponent()
 
        ' Add any initialization after the InitializeComponent() call.
        Dim strHTML As String = String.Empty
        Dim Subject As String = "Service Assignments for " & ReportDate.ToString(myDateFormat)
        Dim oApp As Outlook._Application
        Dim oMsg As Outlook._MailItem
        Dim YesNo As DialogResult = Windows.Forms.DialogResult.Yes
        Dim NoErrors As Boolean
 
        Me.Text = "Service Assignments for " & ReportDate.ToLongDateString
 
        setHeader()
        NoErrors = setData()
        setFooter()
 
        strHTML = reportHeader & reportData.ToString & reportFooter
 
        oApp = New Outlook.Application()
        oMsg = CType(oApp.CreateItem(Outlook.OlItemType.olMailItem), Outlook._MailItem)
 
        oMsg.Subject = Subject
        oMsg.HTMLBody = strHTML
 
        oMsg.To = "DTGOn-RentHelpDesk"
        oMsg.CC = "[email protected]; [email protected]"
 
        oMsg.Importance = Outlook.OlImportance.olImportanceHigh
 
        oMsg.Display()
 
        YesNo = MessageBox.Show("Did the email show up?", Application.ProductName, _
                                MessageBoxButtons.YesNo, MessageBoxIcon.Question, _
                                MessageBoxDefaultButton.Button1)
 
        If Not NoErrors Then
            Me.Close()
        Else
            If YesNo = Windows.Forms.DialogResult.No Then
                ieWeb.Document.Write(strHTML)
                Me.Show()
            Else
                MessageBox.Show("Push Send in the email window to send!", "Send Email Alert", _
                                MessageBoxButtons.OK, MessageBoxIcon.Information)
                NoErrors = False
                oMsg2 = oMsg
            End If
        End If
    End Sub

The error speaks for itself really; you have a non-shared member, and you are trying to access it without using an object reference.
You must create an instance of frmEmail, then you can use the non-shared members on that instance.

About your date-passing question. You seem to be passing a date to the form already (provided that you also fix the thing I mention above), what is not working for you?

I am getting that error with the code you see...

when I change to

vb.net Code:

Dim frm As frmEmail
        Me.Hide()
 
        frm.SetReportDate = #1/23/2012#
        frm.Show()
        frm.Dispose()
 
        Me.Show()

I get an error saying that I'm using before being assigned a value...
if I define it as New frmEmail, then it'll call my code in the New Event but it won't have the date because it hasn't reached that line

I guess my question is, how do I use this code

Dim frm As New frmEmail

and pass it the date?

The basic outline of the way I want them to be handled...

Click on button to email...
gets report data
open an outlook email & put info there
Ask user if outlook email opened,
...if yes, remind user to click on send, close window without ever showing up
...if no, show form with a webbrowser showing the info that way & user manually opens up outlook email


My code is in Public Sub New on frmEmail, I don't want the form to briefly flicker if everything works right. It was working before perfectly, but the form flickered. I'm dealing with non-computer people and they will think something went wrong.

You can make another constructor that allows you to pass the date.

Code:

---

Dim frm As New frmEmail(Date.Today)

Public Sub New frmEmail(ByVal reportDate As Date)
'....
End Sub

---

Thanks, I tried that and it still made my screen flicker thought maybe I did something wrong.

Attempted it again, still flickered, but with a little modification, I set the form's DialogResult
OK (or Abort...if error reading db) so form wouldn't show
Cancel to show from but with the email data on screen to manually email it.

Thank you. This 4 hour headache is finally complete.

You should check if the form is double buffered and make sure it is "True"
