I made asp.net website. I send e-mail via asp.net page to receiver but
receiver cannot get email.
I use smartertool Server SMTP. Sending and receiving to localhost is
working. Sending emails to remote machines is NOT working.

I used these codes to provide a default "Save As" filename for
browsers:
               Response.AppendHeader("Content-Disposition",
"attachment; filename=" + fileName);

Is there a way to get the progressbar value when a user clicks on it ?
I am using wpf at the moment but windows forms solutions would be
welcome too.
I get the the x and y positions of the mouse click but I don't know how

I've already got the code written but for some reason, when i click the
button, nothing occurs. Here is the code.
using System;
using System.Collections.Generic;

My MDI (Parentform) form can have 2 two type of forms (Datagridform and
graphicform).  When users create a new form, they have to pick either child
form.  When those child forms are created and user move the mouse over on one
of the child form, I want the rest of the childs form ...

I am very new to C#.  I have a block of code (a web control) that I
want to include a file.  In my mind, I want to include it in-line,
like php would include a file -- execute any code and then render
html.

Normally, I never have any problems with String.Replace().  However, I
found that I need to replace multiple instances of the character
"ª" (\xAA) with a # symbol.  The input file is a simple one line
file.  I read in the file into a string called strLine.  Then when I

i've read that it is possible to debug custom control property, by
adding in debug features (of the solution/project) :
- start external program => set to devenv.exe (Visual studio exe)
- command lines arguments => the *.sln file

I have the following problem while working with files in asp.net (c#).
Here I create a new XML File with an xslt transformation:
    xslt.transform("source.xml","dest.xml");

In my windows application program, I want to have the abilty to show my
mainForm when the users press F7, no matter where he is (even if he uses the

We are migrating a large app to .net.  There are many forms and there will
be many, many icons.
What are some suggested techniques for more or less sharing imagelists (easy
enough), BUT without giving up the design time experience.

I have a form with about 25-30 TextBoxes, ComboBoxes, etc;  if the user does
not make any changes to the form I don't want to post a "Cancel Changes?"
dialog when they exit the form ... so this is what I'm doing to detect
changes:

A simple dialog that pops up after a menu choice "Set Values..." (for
example), should it inherit from System.Windows.Forms.Form or simply
from System.Windows.Forms.CommonDialog? Problem is that I can hardly
find examples on the latter

I've created a Download Manager application and I'm having a problem
with some clients where for whatever reason, the remote connection is
forceably closed (whether on the client side or server side I'm not
sure).

I have a form that I need to place 3 buttons on.  I would like the 3
buttons to call the same method, perhaps with different arguments.
In Powerbuilder, I could create a visual button object and code for
it, then inherit from that and place it on my form/window.
