i am new to vb.net. i would like to create a class for sending emial . i tried the script online but i failed to send. So i got this code below from the hosting server. May i know how do i simplify the below script to just receive FromEmail, Subject, Message ? why it needs the mailerpath?mailerport? and errText? isn't we can check those error in the form instead of class ? Please kindly advice. thanks <pre> ' **** MailerPath = Your SMTP path (for eg: mail.[domain].com) *** function CDOSYS_Mailer(Message, FromEmail, ToEmail, FromName, ToName, Subject, MailerPath, MailerPort, errText, searchURL) on error resume next dim Mailer set Mailer = server.createobject("CDO.Message") if err.number <> 0 then errText = displayError("CDOSYS", searchURL, err.Number, err.Source, err.Description) CDOSYS_Mailer = false : set Mailer = nothing : err.clear() : err = 0 exit function end if Mailer.From = FromName & " <" & FromEmail & ">" Mailer.To = ToName & " <" & ToEmail & ">" Mailer.TextBody = Message Mailer.Subject = Subject with Mailer.Configuration .Fields("http://schemas.microsoft.com/cdo/configuration/sendusing") = 2 .Fields("http://schemas.microsoft.com/cdo/configuration/smtpserver") = MailerPath .Fields("http://schemas.microsoft.com/cdo/configuration/smtpserverport") = MailerPort .Fields("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate")=1 .Fields("http://schemas.microsoft.com/cdo/configuration/sendusername")="test@yourdomain.com" .Fields("http://schemas.microsoft.com/cdo/configuration/sendpassword")="youremailpassword" .Fields.Update end with Mailer.Send if err.number <> 0 then errText = displayError("CDOSYS", searchURL, err.Number, err.Source, err.Description) CDOSYS_Mailer = false : set Mailer = nothing : err.clear() : err = 0 exit function end if set Mailer = Nothing CDOSYS_Mailer = true end function</pre>

public bool IsInteger(string sender) { Regex regex = new Regex("[^0-9]"); return !regex.IsMatch(sender); } hi i get confused with the code above... why when i put e.g. 333 as the sender.. regex.IsMatch(sender); this is returning false ?? and i must put a ! there ?? my logic is .. when regex[^0-9] = integer then it must return true... pls advice

thanks for the wonderful reply... BUT .. i just cant get the $#&(#$ manager Error 3 The name 'ConfigurationManager' does not exist in the current context i had put the below script in the constructor as what u told..also added the using System.Configuration;

this.connectionString = ConfigurationManager.AppSettings["connectionString"];

but just no manager come out..

i declare under this.. as global.. i do not want each function declare that.. namespace ttt { public class Dataaccess { private string sqlString = System.Configuration.ConfigurationSettings.AppSettings["connectionString"].ToString(); private SqlConnection cn;

yes.. i had added.. the using System.Configuration but still don have the manager thing.

after included i cant find the COnfigurationManager also ... system.configuration. only have .ConfigurationSettings and .ConfigurationException

may i know how to clear this error ? i tried use this System.Configuration.ConfigurationManager.AppSettings' but i canot find the .configurationManager.. private string sqlString = System.Configuration.ConfigurationSettings.AppSettings["connectionString"].ToString(); Warning 2 'System.Configuration.ConfigurationSettings.AppSettings' is obsolete: 'This method is obsolete, it has been replaced by System.Configuration!System.Configuration.ConfigurationManager.AppSettings'

Thank for the reply.. can u pls show some example to get all verification done is the class ? or at least guide me on declaring or passing the e thanks

hi i would like to seperate my design page from validation. so i put the validation code in e.g validate.cs design form

private void textboxInteger_KeyPress(object sender, System.Windows.Forms.KeyPressEventArgs e)
{
validate.txtIntValidate(txtPhone.text)
}

in my validate class

class Validate
{
public bool txtIntValidate(string txt)
{
if (!Char.IsDigit(e.KeyChar) && e.KeyChar != (char)8)
{
e.Handled = true; // input is not passed on to the control(TextBox)
}
}
}

BUT in the validate.cs class .. how do i declare the e.. Error 3 The name 'e' does not exist in the current context

can .NET run in UNIX ?

In a large organization, if you have UNIX applications, mainframe applications, Windows applications, etc. How do you get these to talk to each other? may i know how .NET solve this problem ? also, during deployment,we have to worry about which version of IE is installed, which version of MDAC is installed, etc. we may have to test our install on Windows 95, 98, ME, NT, 2000, and XP, with different service packs, to insure that the install and uninstall work correctly. may i know how .NET solve this ?

class A { public virtual void F() {} } class B: A { new private void F() {} // Hides A.F within B } class C: B { public override void F() {} // Ok, overrides A.F } may i knwo whta is Hides A.F within B and overrides A.F ?? thanks
