Use Variables For Setting 'From' Property In Net.Mail.MailMessage?

Oct 6, 2010

.From = New MailAddress("Me@MySite.com", "Big Mike")This does not;

Dim AddressFrom As String = "Me@MySite.com"
Dim FromDisplayName As String = "Big Mike"
.From = New MailAddress(AddressFrom , FromDisplayName)

I receive the error; The specified string is not in the form required for an e-mail address.I would REALLY like to use variables here so that I can read these two pieces of data from My.Settings. I've been searching for the answer for hours and I'm stumped.

Moving From Web.Mail To Net.Mail, Replacing MailMessage.Fields?

Jan 31, 2011

I'm trying to update some older software which uses the now-declared-obsolete System.Web.Mail classes.Unfortunately, I don't really know a heck of a lot about email, so I'm looking for advice.

Here is the fragment of code I'm looking at revising:

[Code]...

From what I can tell, this should be configuring some kind of sending option. I can kind of work out what's going on, but I don't know how I should go about re-implementing it.It's looking like the place to be putting this stuff is now in the System.Net.Mail.SmtpClient.Credentials class, but the information in there doesn't seem to bear any resemblance to what I have here.I'm almost certain I'm making some obvious error, here, but I can't see it. Can someone tell me what I should be doing?

Email Generated Using System.Net.Mail.MailMessage Reformatted On Forward?

Nov 18, 2011

I had a requirement to gloss up an email generated from bespoke system using 'mailto' to be glossed up. I don't believe I can produce HTML message using mailto so I decided to generate the mail using System.net.Mail.mailMessage. However, as the client wants to add to the email prior to sending it on I need to send it to the client's own email, allow them to edit using their email editor and they would then forward it to the target recipientUnfortunately, the tables on forwarding are reformatted.

Multithreading: Reading/setting Variables, And Passing Variables?

Mar 8, 2011

Question 1: What is the difference between "Background Worker" and "Worker Pool" as indicated within the MSDN samples provided.

Question 2: I noticed while using, AddressOf _Function_, variables cannot be passed; what would be an efficient solution to this?

Question 3: While using multithreading is it required to invoke before setting variables, or only form properties?

Question 4: While using System.Net.Sockets is it safe/efficient to use Application.DoEvents while waiting for new data; or would be using a Do While loop be fine without DoEvents since the action would be multithreaded? Note: there can be up to 2000-3000 sockets in use at a time.

Setting Variables To Store User Setting For Applications

Feb 13, 2012

In our projects we use setting variables to store user setting for the applications. Moreover, with every latest version of the applications, we upgrade these variables to retain user settings.Normally, this works fine, but recently one of my end user reported an error i.e.Configuration System failed to initialize". The error is related to user.config file. Therefore we requested the user to send us his file.After received the folder, we noticed that it contains 3 files (3begfjb.newcfg,3begfjb.tmp and user. config). 3begfjb.tmp is an empty file, while 3begfjb.newcfg and user.config are identical files. We tried to open these files but the data in user.config isn't proper xml rather its unreadable formatted file.Do any you guys had experienced this sort of issue or any ideas how and what may have created these files and corrupted user.config file.

Validate A Value Passed To The Property Before Setting The Property?

In on a section of my book about classes and properties. In this example, the author is attempting to show how you can validate a value passed to the property before setting the property.

How do I get MyClass1 to persist, meaning how do I get access to that variable outside of the Sub that instantiates it?

Setting Variables To Use As File Names?

Sep 10, 2009

We have this current VBA program to help us with AutoCAD via the use of a template excel sheet.The setup we have created works well; however occasionally we have two drawings per folder, which often results in, two templates excel sheets of the same name, one overwriting the other. how I can set the active drawing name in a variable that our program uses to check for, then if not present that it creates a copy of out template and then saves it as the active drawings file name which was set as the variable

This would allow our program to locate the associated excel sheet by name then save it by the unique drawing name and prevent existing excel files being overwritten if in the same folder.

;===CODE STARTS HERE===
Option Explicit
Private Objexcel As Excel.Application
Private ObjWorkbook As Workbook

Quick Technique Of Setting / Saving Variables

Dec 26, 2011

I know this is a VB.Net messageboard, but it can work with in all languages. Is there a quick way to complete a line (sample code):
//Setting variables set 1
a = e;
b = f;
c = g;
d = h;
.....

//Saving changes set 2
e = a;
f = b;
g = c;
h = d;
without having to type everything out...A technique using EXCEL or Notepad....Find and Replace. This would save a lot of time coding and becomes pain in the butt when you working with many variables.

Setting Global Variables Within Web Project On Login And Set Expiry Time

Dec 1, 2011

I'm developing a revised version of a system I have been using for years, but with all the advantages of .NET features that were not around when I first made this. It's proving a steep learning curve! So, when a user logs in through my Login.aspx page which simply compares username/password to Database record, the system creates a session variable containing the user's Username and various other things. There are two type of variable which will be common to all elements of this system
User Specific data, Username, Permissions, etc

Setting variables, drawn from a database of pre-set facilities which are setup within the system, some will determine which facilities work, how they work, and some will be dependent upon the User's permission. Obviously, I could set everything within the Session data, but that'd be inefficient wouldn't it? If I were to set these globally available variables in my App_Code, how would I go about setting this up so that, for example, those variables which require a database call, are set for the duration of the Logged-In session and do not require constant Database lookups? Further to that, those variables which are dependent on the session state, would need clearing on each LogOut. I am using VB.NET.

Setting Label Property In Web Control?

Nov 8, 2010

I am converting a 1.1 .NET web app to 3.5, and I've run into a bit of a jam.

One web control has a Property that sets the page title label on that web control.

End Property

When a page with the web control was loaded before, it would set the Property to a given string, like in ucHeader.PageTitle = "This is a string." Now, if I don't remove the lblPageTitle.Text = Value, I get a NullReference Exception.

Setting Property Of Class (LifeLine)

May 1, 2010

I'm new to classes. In my Who wants to be a Millionaire application, I have a Lifeline class and I create three instances of it - FF, PAF and ATA (50/50, Phone a Friend and Ask the Audience). Something I do with a lifeline is put a cross over its logo, hence the need for a centrepoint property, which marks the centre of the cross on a form.

Public Class Lifeline
Private ptCentrePoint As Point
Public Property CentrePoint() As Point
Get
CentrePoint = ptCentrePoint
[Code] .....

What happens is that at the "Call Form2.DrawCross(Form2.CentrePoint)" line, the tooltip shows that the FF object's centrepoint property isn't set (as I thought it would be by " FF.CentrePoint = tmpPoint").

.net - FormView With EntityDataSource, Setting Where Property Causes Error

Aug 10, 2011

I have this simple code,

Protected Sub grdSearch_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles grdSearch.SelectedIndexChanged
TimeOff.Where = "UserName=""" & grdSearch.SelectedValue & """"
End Sub

Doing so causes this error, 'UserName' could not be resolved in the current scope or context. Make sure that all referenced variables are in scope, that required schemas are loaded, and that namespaces are referenced correctly. Near simple identifier, line 6, column 1.

The datasource works fine before the where property is set.Update: I found the issue but I still don't get it.Adding it. in the where clause solves the issue. Like this,

TimeOff.Where = "it.UserName=""" & grdSearch.SelectedValue & """"

When I set the property from my main program i am getting an error "Invalid attempt to call Read when reader is closed." When i gone to the online help i got the message as follows "System.InvalidOperationException (.NET Framework 4)The exception that is thrown when a method call is invalid for the object's current state. InvalidOperationException is used in cases when the failure to invoke a method is caused by reasons other than invalid arguments.

If the method invocation failure is due to invalid arguments, then ArgumentException or one of its derived classes, ArgumentNullException or ArgumentOutOfRangeException, should be thrown instead.[code]
