Hi this is kind of an embarassing question- do I actually need to run an SMTP server to send an email? What I want to do is have my desktop windows app (Form) send an email when the user clicks a button. If the user installs my app, do I need to also install an SMTP sever on the user's local machine?

I've read a lot about using the System.Web.Mail stuff. But I'm getting the "Could not access 'CDO.Message' object." error when I set SmtpMail.SmtpServer="localhost".

I tried all the suggested fixes- I have Outlook installed, I'm using valid addresses for To and From, I tried setting SmtpMail.SmtpServer to "".

Do I have to install an SMTP server on the user's machine in order to send an email?

thanks

No...you just need to point to the user's SMTP server at their ISP...

Well, thanks but that won't do. I have verizon, for examle, and Verizon doesn't let you send email where the From address is anything besides the email address verizon gives you. If you want to send email From any other address you have to use a different SMTP server. Also where could I find out what the user's ISP's SMTP server is? Like if they don't have Outlook installed, or it's not set up (wrong or missing SMTP for example).

thanks anyway for your response.

Here's an idea, if you have Outlook installed in the user's machine, why not just use the Outlook Com object.Add a reference to the Com, and add the following code:

Outlook.Application ol = new Outlook.Application();
Outlook.MailItem ml;
ml = ol.CreateItem(olMailItem);

ml.Body = "message body";
ml.To = email address;
ml.SenderName = your email;
ml.Send();

warning: the code above is modified from vba, so it might not exactly like expected.

This is a new one- I haven't seen anyone mention this.

If the use doesn't have outlook installed, then obviously this won't work. So I'm still probably better off installing an SMTP server on the users local machine instead.

Hey, if the user has Outlook installed, but the user didn't specify an SMTP server for outlook (or specified an incorrect one), then this won't work right? Or is it like using the underlying internal SMTP server of outlook itself or something? See, like me for example- I have outlook installed but I never use it- I use Eudora, so I never told Outlook what SMTP server to use.

thanks for your response,

Yea this is exactly what I did, and I got the error I described. But thanks for your response anyway.

I have a class that represents a table. I want to save it to the database.

I could sen all of the pertinent data that needs to be changed then build it in store procs to write

or i could send a copy of all data to the stored procs

I would like to build it in stored procs but is there a way to avoid building a string to execute?

I am using a richtextbox in winforms.

When the wordwrap property us set to true i cannot find a way to select the current / any other paragraph within the control.

it seems that some of the methods / api functions return some values in logical lines unit and some in physical lines units.

is ther a way to find a line / paragraph break in the control.

You can display a web page in the "internet explorer control", and of course you can generate text and save it as a html file.
But why do you want to do it?
You can write a web application in C#, so you don't need to generate the page in a windows application.

Thank Kannan Kalyanaraman & Corinna John.

I do this because I have never developed any web application and have absolutely no idea what web application is like. I was thinking about trying to develop a web application, but I was told that it's complicated. Because I need to develop the server side to provide webservice.

Now what I am developing a tool to compare selected records in selected tables(could be more than 2). I already finished most of functions using Windows form. Also I have a windows form to show the compare result, highlight the difference.

Having the idea of putting the webpage in my windows application, is because I don't like the way I am doing now. If I can show the result in a webpage, then user can save it to wherever they want and also the appearance of webpage is nicer than a form.

I am new in .Net programming. So if you have any suggestion for me, please don't hesitate to tell me.

Thanks again.

Its really easy, especially when you think about all the intricasies involved in a win app. There really is no need to make it a windows app. You'll have install, mainaining, and other problems. Design your 3 page web site in asp.net its soooooo much easier.

And dont listen to them thier probably VB programmers
