I think the problem is related to Access Rights on the Program Folders folder. You may need your program to operate with Administrative rights in order to acces it.

User:Errr...ummm....no.
Me: Can you see an arrow that points upwards?
User: Oh yes, I see it now!

shared user data is supposed to be in the Program Files\Common Files\Company Name(optional?)\App Name folder. That's been the way it's supposed to be done since XP if not earlier. You can force your app to still do so, but you'll end up hammering your users with UAC dialogs in the process.

You call the Read method repeatedly, until it returns a number of zero bytes. Just like reading any stream.

Write the bytes to a MemoryStream, then you can access the data once you are done reading. Basically thr MemoryStream will allocate an initial array, then keep moving the data to a larger and larger array as needed.

If you need to support large amounts of data use a FileStream instead.

It should be easy enough to convert. There's tons of ways of doing this anyhow, all pretty straightforward.

Compile it, then open the DLL in .NET reflector and disassemble as C#. I have not said this is the best way, but it certainly is a way. Wink | ;)

Why do you need to do this? It's .NET and presumably it's should be CLS Compliant which means that it should be accessible from your assembly.

ReferenceEquals and checking for null

Rob Philpott10-Oct-07 0:59

Where I'm working at the moment, I'm seeing a lot of this sort of thing:

if (ReferenceEquals(curve, null))
{
    // do something
}

whereas I would personally just use:

if (curve == null)
{
    // do something
}

Now I know that equality is more complicated than it sounds, so my question is, is there any merit in using the first approach over the second?

Rob Philpott.

Well, IMHO ReferenceEquals method, when used to compare a reference with null, it's merely redundant.

That would depend on where it is used.

For example: When you override the == operator, you may want to use ReferenceEquals() so that you don't end up with an infinite loop or other undesired effect.

Activate an existing browser session with a .Net executable

Hello,

I'm looking for a way to activate an existing browser session by means of a C# .Net executable.
I have found some code where I would be able to look for all active programs, and eventually even kill them. I did not find a way to activate a process, however.

private void button1_Click(object sender, System.EventArgs e)
{
System.Diagnostics.Process[] myProcesses;
myProcesses = System.Diagnostics.Process.GetProcesses();

foreach (System.Diagnostics.Process instance in myProcesses)
{
MessageBox.Show (instance.MainWindowTitle);
instance.Kill();
}
}

I need this to avoid the user to have logged in again.
I want to activate his open internet session, and eventually even refresh his session with a new url.
E.g.
http://localhost/sid=abc123?nameId=10
should be replaced by
http://localhost/sid=abc123?nameId=20 , in the same session, and triggered by an executable.

Is this possible ?

Help would be very much appreciated.

Sending Mail using MAPI

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,
