Sending Mail using MAPI

M. J. Jaya Chitra10-Oct-07 0:32

Hai all,

I have to send mails through MAPI.

I have gone through the articles given in code project.

I have created a sample application. But when the send() method is called it is prompting a dialog box intimating an application is trying to send mail automatically... ... from the Microsoft outlook application. While clicking on the "Yes" option it is sending the mail.

But the above task should be automated in my module and it has to be done in a windows service.

Can any one give me a solution to perform the above without displaying the message box.

Thanks a lot in advance.

Best Regards,
M. J. Jaya Chitra

Is there a reason you have to use MAPI over SMTP?

In this[^] example they specify the user cannot edit the message (which I believe means it is not shown to them).

Take care,
Tom

Yes, because i have to have the items in the "Send Items" folder of the outlook.

That makes sense. Can you post the code that you are using to call MAPISendMail?

Take care,

You are using the Outlook interop, not MAPI (even though you are getting the MAPI namespace). If you look at the documentation[^] for the MailItem.Send method, you will see that it says the dialog will be shown. This is a security measure, so I doubt you would be able to programmatically suppress it.

You should be able to configure the Outlook UI to suppress it though (depending on your version). I'm running Outlook 2007, and I can disable it under the "Tools->Trust Center..." menu item. In the dialog select "Programmatic Access", and select the "Never warn me..." option. This is not recommended by Microsoft or me.

Take care,
Tom

I am using Microsoft Outlook 2003, so where can i find this option.

Sorry, I don't have Outlook 2003, so you'll have to find it yourself. This[^] may help though.

the static keyword

Hi,
I'm new to programming in C#, actually learning under someone. I recently saw the following line of code in the code-behind of an ASP.NET Web application page :

//all the other autogenerated codes

static DataSet dSet; // explain this line please.

What does it mean to make a DataSet static?

Thanks for your time. Smile | :)

Hi, Obinna. In an ASP.NET project, this makes no difference, because of how ASP.NET works. In general, it means that if you have a class like this:

class Widget
{
public static int widgetCount = 0;
}

then the value of widgetCount is the same across all instances of the program. If the Widget constructor looked like this:

public Widget()
{
++widgetCount;
}

Then, every widget would have the same value, and it woild not be 1, it would be equal to the number of widgets that had been created. In fact, in C#, if you do this:

Widget w = new Widget();
int n = w.widgetCount;

The compiler would not allow it. You need to do this:

int n = Widget.widgetCount;

Could you tell any sample scenario where we need to use this kind of increment ? i don't find any use of incrementing the static value.

Well, a count of objects seemed like a decent real world example. Another may be a database connection string. Basically, if the value is always the same, or if it is a value you want to be able to make all instances aware of, static does that for you.

Once you know how it works, if you ever need it, you'll know.

As an ASP.NET application is multi threaded, it makes a huge difference. A static variable will be shared across all threads, so they are rarely used at all in ASP.NET applications.

If you want to have some data that is used by all threads, it's often better to put it in the Application.Items collection, and populate it from Application_Start in global.asax.

So, if you store something as a static variable in a page, when a new page instance gets created, that value has been stored ? I didn't think so.

Yes. The static variable belong to the class rather than the class instance. The static variable exists before there are any instances.

So does it mean that the content of the instatiated DataSet cannot be changed anywhere in the program? what exactly?

You can change the DataSet, but then you have to use locking for every access to it, so that one thread can't read it while another thread is changing it.

Starting animation defined in XAML from code

Hi Obinna,

Going back a bit because you're probably not familiar with multiple threading yet, the static keyword marks the variable as being shared across all instances of the class.

so for instance if you have a class member which is an int:

public class MyClass
{
    int z;
}

each and every instance of that class you create (new MyClass()) will have its own z, which can and usually will be different.

when its static:

public class MyClass
{
    static int z;
}

then each and every instance shares just a single z. If you change it in one instance, it will change in all instances. As said previously, this could be useful if you wanted to maintain a count of how many instances are in existence and have that variable in class scope.

Similiarly, if you had a database connection string, that would be the same for each instance so you would mart it static so that you didn't create multiple copies of the same thing but instead just have one which each instance can access.

Regards,
Rob Philpott.

Hi,

I've posted this on the Microsoft forums as well but have not received any usable answer. I have a storyboard in XAML (in a DataTemplate) that I need to start from code. Now I've given up on that idea and rather went with an event to start it. Note: This is WPF.

instead of:
<code>
<Border.Triggers>
<EventTrigger RoutedEvent="Grid.MouseRightButtonDown">
<BeginStoryboard>
</code>
I now have:
<code>
<Border.Triggers>
<EventTrigger RoutedEvent="local:TouchActor.gestureMade">
<BeginStoryboard>
</code>

gestureMade is an event I created. Which is defined in code as:

<code>
public static readonly RoutedEvent gestureMadeEvent = EventManager.RegisterRoutedEvent("gestureMade", RoutingStrategy.Bubble, typeof(gestureMadeHandler), typeof(TouchActor));

public delegate void gestureMadeHandler( object sender, GestureEventArgs e );

public event gestureMadeHandler gestureMade
{
add { AddHandler(gestureMadeEvent, value); }
remove { RemoveHandler(gestureMadeEvent, value); }
}
</code>

I know the event gets raised because I have a MessageBox that pops up in the handler. The problem is that it doesn't trigger the animation. Am I missing something?

rather have something you don't need, than need something you don't have
