Hi,
Quite new to C# and Visual Studio, but here's my question..
I'm on a project that uses Windows Forms with a RichTextBox.
The text that is imported/typed in this box is copied to another RichTextBox, that eventually change this text to a Scrolling Text, from right to left on the screen. Searched the net for something like this, but I had no real luck finding it, except for the DougScrollingTextCtrl. Though this is not that user friendly in my opinion.
Is there anything I could think of to create something like this?
Thanks in advance.

Im not sure if this would be possile, but could you try using spaces?
Like this:
make a timer
-while(text doesn't go offscreen? <-- thats the bit im not sure about)
-text = " " + text;
then once it reaches t'other side, trim the first character for as long as it is " "
Then repeat, i don't have any code for this, its just an idea.

Thank you for the respond,
Thought about something like this as well, though this makes the screen flicker a bit, cause it's one char after another. Would like to see it smoothen out and for the user able to change the speed it scrolls. Said I used a RichTextBox, so the user can put text in there, but doesn't matter what control is used for the scrollingtext.
I'll be looking into it, cause it's a start anyways.

Hi all,
I need to know how to authenticate a user before sending a mail using a
C# application.
The source code i use is this:
private void sendMailButton_Click(object sender, EventArgs e)
{
try
{
MailMessage mailMessage = new
MailMessage(toTextBox.Text, fromTextBox.Text, subjectTextBox.Text,
bodyTextBox.Text);
SmtpClient obj = new SmtpClient(SMTPTextBox.Text);
obj.Send(mailMessage);
MessageBox.Show("Message Sent");
}
catch (Exception ex)
{
MessageBox.Show("message not sent");
}
}
I need to add the authentication part. This is working but with no
authentication for the user or the mail sender address. I am using a
local SMTP server.
Thanks,
Jamil Abou khalil

Hi,
Iam new to C# , can any one help me to create property within an property in propertygrid (ie) i should have Expandable symbol for a property that doesnt include category .
Thank you
Regards

Hi Praveen,
In the Microsoft PropertyGrid, you can't create directly a property under another property. You must do it like a Font or a Pen does it. For example, if you have a Font property in your target instance, you will be able to see it in the grid and to expand it to see the published properties underneath. This trick is achieved by the FontConverter class. If you look its source code into Reflector you will see how GetProperties() returns a set of customized properties and how CreateInstance() reacreates a font instance with the values of these properties. Studying these classes can help you a lot understand how the propertygrid works. Hope that helps.

There are zip classes in .NET 2.0, but is that really what you want ? Or do you want to compact the database ?

Hey all,
I need to describe what I'm doing before I can ask my question, so bear with me.
I have implemented a 'limited-heap' where N columns of my DataRow define unqueness.
And M different columns define the sort order so that I can discard rows beyond arbitary MaxRows.
I have a Dictionary<int64,datarow> (ie: a hash table with order(1) lookup)
and a SortedDictionary<int64,int64> (ie: a balanced tree on the key).
I make an Int64 Key from the N Columns in the row, If it exists in my heap I aggregrate some of the data and increment a counter. If it does Not exist I add it.
All this uses the Dictionary<>
Now the magic bit I need to remove the Least Significant row as defined by the M Columns.
So I need them sorted. So I add it to the SortedDictionary<>.
Then If I have More than MaxRows in there, I lookup the first row in my SortedDictionary and remove it from both. (Note that the Value section of the SortedDictionary is not needed).
Now my Question:
I implemented this twice. In the first one I put the Int64 key value from the Dictionary as my key value in my SortedDictionary, then I supplied a Comparer to lookup the Dictionary for the value to compare.
In the second I put the actual DataRow in the SortedDictionary and made sure the comparer used this instead.
Why would this be slower?
My Inserts and Removes from the SortedDictionary was were I lost performace, but I dont know why.
All I can think of is that the referene to the dataRow is bigger than the Int64 keyvalue. And therefore required more memory (but this is my c++ head thinking here, and I don't know if this applies in c#)
Thoughts anyone?
nb: Sorry to be so long.

Presumably, you have a huge list if you're using an Int64 ?
My guess would be that an int can be compared to an int, nice and easy. If you have two datarows, you need to look up a value in both before you can do a comparison. Or am I wrong, you're just checking if two datarows are references to the same object ? Either way, you've gone from POD to a complex type being passed around and compared.
