Re: question about a WEIRD problem in sending mail using smtp client.

10-Sep-06 3:16

Yes that is a AV symptom.

To have the workaround, create a security and permission descriptor, usint the AV API using the Interop, and assign it to the context before making a call to Send. This exclusive permission will let the application send the mail without hitch.

There are other ways, like masquerading the hooks isntalled by the AV etc, but then they should be used in only extreme scenarios.

Let me knwo if you got it.

Hey

well, it works with the console thing.
I really prefer not to post a warning and fix it this way because many users are using norton.

Thanks alot! Smile | :)

Thanks alot for you help!

brief question about sending a message to a control

9-Sep-06 21:53

Hey, thanks for your help.

I'm sending an e-mail in the most simple way I can think of.
after I'm using smtp.Send() nothing happens, only after I close the app.

MailAddress sender1 = new MailAddress("none@unknown.com");<br />
MailAddress rcpt = new MailAddress("green.fuzer@gmail.com");<br />
<br />
MailMessage mailMsg = new MailMessage(sender1, rcpt);<br />
<br />
mailMsg.Subject = "Test Mail Sender";<br />
mailMsg.Body = "Body Testing";<br />
smtp.Send(mailMsg);

Re: brief question about sending a message to a control

9-Sep-06 9:29

I have this RichTextBox. I want to send it the message behind the Keys.PageDown key. Seems to me it worked if I used the OnKeyPress, but OnKeyPress takes a char, not a Keys enum (so I tried to use OnKeyDown/OnKeyUp, but it didn't do anything).

I figured I could then try RichTextBox.ProcessKeyEventArgs, but then I quickly learned that it took a ref Message argument, not a KeyEventArgs argument (kinda deceptive if you ask me).

So, I tried to start giving it the right message, but I'm stuck on the last three parameters of Message.Create(). Where do I find a list of int messages (and its appropriate wparam and lparam arguments)?

I've tried looking in my MSDN, but "message" is kind of a vague term to look for (I looked and didn't see anything useful). And I tried to do a search on CP, but didn't see what I'm looking for.

All I want to send it is the pagedown key message. Can someone please help me fill in the blanks?:

public class myRichTextBox : RichTextBox
{
	public void PageDown()
	{
		base.ProcessKeyEventArgs(ref Message.Create(this.Handle, [what goes here?]));
	}
}

Put in something like this:

Message msg = Message.Create(this.Handle, WM_KEYDOWN, new IntPtr((int)e.KeyCode), IntPtr.Zero);
base.WndProc(ref msg);
e.Handled = true;

DLLImport User32.DLL and declare WM_KEYDOWN message as:
public readonly static int WM_KEYDOWN = 0x0100;

Let me know if you got that!

Arjun "Mjolnir" Bahree, you rock.

It works perfectly, except that I had to take out the DllImport line because the compiler (just csc.exe) was giving me:

error CS0592: Attribute 'System.Runtime.InteropServices.DllImport' is
not valid on this declaration type. It is valid on 'method' declarations only.

However, I do have one little question... since I'm sending it a WM_KEYDOWN message, do I have to send it a keyup message as well? Will it think I'm holding down the pagedown key if I don't send it a keyup message?

(I just shortened the pre text so that it wouldn't stretch the browser window out)

Ohhh! The DLLImport line was for some more tasks that you could have achieved but I did not mentione for brevity's sake. And ideally it is meant to import user32.dll.

Yes you need to send keyup message. Else it will keep on sending the pagedown messages to the control.

Re: brief question about sending a message to a control

9-Sep-06 10:26

I wasn't sure if I should send it a keyup message as well (so it won't think I'm holding the key down), so I added it (WM_KEYUP, 0x0101).

By the way, a little while ago I found a list of windows messages (Googling "list of windows messages"), but didn't know how to use them.

Thank you, Arjun "Mjolnir" Bahree!

Super work on starting with windows messages.....Read Petzold! Awesome work! Bible for a programmer! You will find the mechanics of Win Messages there at least to start with. Also I suggest you to have a look at Windows.h and maybe that will give you some surprise info? Smile | :)

I thought Windows.h was only a C++ thing (I used to do C++)...
I thought that once I'd seen the light and converted to C#, I wouldn't need to hassle with header files anymore...

How would having a look at Windows.h help me out?

is there a winform label control

10-Sep-06 3:10

Well windows.h will give you an insight onto the #define for the numerous messages that windows throws.

Using the same stuff, as in WM_KEYDOWN and the likes, you can code trapping of the rest messages. That's the most comprehensive message list you can get for a Win platform.

Yes its a C++ thing and that is still the game beneath C#, after all its all the win messages that get raised, which are beautifully wrapped by .NET system events.

That's just for learning and reference purposes. You do not have to hassle with header files anymore, but for interacting with native mechanism this info is important.

is there a winform label control that can support HTML tags?

I dont want to use richtextbox. Smile | :)

Arjun "Mjolnir" Bahree9-Sep-06 9:34

From what i understand, you need a label control and not a textbox.
There is no inbuilt control for that for winforms as such.

However, on similar lines, you can use this one by Palomraz

http://www.codeproject.com/vb/net/rtflabelcp.asp

Doe that solve your purpose, or am I not near your question?

thanks for the reply Smile | :)

i have already seen that solution and it seems you have to call an .rtf file to display as the label content.

what i wanted is a simple label control that can support HTML tag so when i do this for example:

The total transaction for this account is <b>100,000.00</b>, please be notified.

so by doing this i can only select the portion of the sentence to be bold or colored.

Arjun "Mjolnir" Bahree9-Sep-06 10:39

OK now i understand.

So for this you can override the label control, and use the EmbedHTML/MapHTML script display inline HTML, which is what RichTextBox uses internally.

OK. The way I did it was by hosting an .htc inside my custom control.
This HTc did the trick of acting like a label.

The equivalent for RMI in .NET is remoting. Search and checkout the articles on this website to get an idea of what it is and how you can start building with it.
