I got my last problem to work but now i have a new one. My program works great on my computer(where i made it) but every other computer i try to open it on it gives an error message. the program doesnt even come up just the error msg. Ive tried it on 2 computers that both have .net with no luck.


If you want to try to open the file yourself here is the link to download:





Script(although I think it is working fine):

Imports System.Net.Mail
Public Class Form1
Dim y As Integer
Dim x As Integer
Dim z As Integer

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

If TextBox1.Text.ToLower.Contains("@hotmail") Or TextBox1.Text.ToLower.Contains("@live") Or TextBox1.Text.ToLower.Contains("@msn") Then
x = 4
ElseIf TextBox1.Text.ToLower.Contains("@gmail") Then
x = 2
y = 2
z = 1
ElseIf TextBox1.Text.ToLower.Contains("@aol") Then
x = 2
y = 3
z = 1
ElseIf TextBox1.Text.ToLower.Contains("@yahoo") Then
x = 5
End If


'-----------------------------------------------------------------------------------------------------------------
'This is for Yahoo
If x = 5 Then
start1:


Dim oSmtp As New EASendMailObjLib.Mail

Form2.Label2.Text = Val(Form2.Label2.Text) + 1


oSmtp.LicenseCode = "TryIt"


oSmtp.FromAddr = TextBox1.Text


oSmtp.AddRecipientEx(TextBox3.Text, 0)

oSmtp.Subject = TextBox5.Text

oSmtp.BodyText = RichTextBox1.Text

oSmtp.ServerAddr = "smtp.mail.yahoo.com"

oSmtp.UserName = TextBox1.Text

oSmtp.Password = TextBox2.Text

oSmtp.ServerPort = 465

oSmtp.SSL_init()

If oSmtp.AddAttachment(TextBox6.Text) <> 0 Then

End If

Form2.Show()
Else
MsgBox("ERROR" & oSmtp.GetLastErrDescription())


End If

If DialogResult = Windows.Forms.DialogResult.OK Then

Dim objreader As New System.IO.StreamReader(OpenDLG.FileName)

TextBox6.Text = objreader.ReadToEnd

objreader.Close()

TextBox6.Text = OpenDLG.FileName.ToString()

The error says "sorry but the program has incountered an error and has to close" and it wants me to send an error report to microsoft.

Rather upload the project source files.
but every other computer i try to open it on it gives an error message
The project uses a COM library, which must be installed in other computer. Isn't SmtpClient sufficient?
 
I installed the Com

I installed the com on the computer that i was testing it on. it still didnt work. What do you mean by "is the SMTp Sufficient"?
 
SmtpClient that you're already using is the .Net Framework class for sending mail, why do you need another mail sending class?
 
Smtp

I used it because some email providers, like Hotmail, require a SSL connection. I didnt know how to do that with the regular one.

Using SMTP

When I started the project, I used it. Then I got errors for hotmail and yahoo. I looked it up and found somewhere that said to get a SSL conections you need to use the EASend. So I wrote that for the Yahoo and Hotmail portions. Do you think if I converted it all over to the SMTP, it would fix my problem. BTW thanks for the help. I just realized that I added the enablessl later on.
