richtextbox edit control and events - help!

winForms - C#

This should be simple. Does the richtextbox control support dragging and dropping?

I know of the DoDragDrop method. It doesn't help me if I can't interrogate the system to find out what the mouse is actually dragging.

I've written a bunch of custom event handling to deal with this, but the last thing I'm missing is the event arguments you would normally get in a DragEventHandler. And short of changing the signatures on delegate event handlers (doesn't work, obviously), I'm not sure how to get the mouse args.

Is there any easier way to do this? Does the RTB actually support easier DND capability?

Thanks in advance.

Yes, it is supported. Search MSDN, in particular, try here[^].

how to program a scalable server application?

Hi all,

Are there any references for writing a scalable server application ?
I searched on internet but find nothing, just can find some
product info on scalable server application.

Thanks

There's no easy answer for this. It's just like saying "how to create a beautiful painting?", or "how to create fast software?". There are some techniques that you should avoid, because they're not scalable, but there are lots of ways of developing scalable server software.
Since you're in a .NET forum, you can start here: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vsent7/html/vxconbestpracticesstrategiesforscalability.asp[^]
MSDN has a lot of extremely good articles about scalability, I suggest you to read everything you can about scalability there, if you're really interested on it.

Yes, even I am blogging now!

I agree with Daniel, there are lot of things that play into effect when designing such application. Here's a patterns & practices book I recommend for you: http://msdn.microsoft.com/architecture/patterns/default.aspx?pull=/library/en-us/dnpatterns/html/esp.asp[^]

Browse through the patterns to get a feel for some of concepts you will like your application to implement.

Change behaviour on WM_ERASEBKGND

Hi,

I wrote a little C# program that should be able to catch messages to a window from a 4GL application and change the default behaviour.
I struggle with the repaint of an icon. It gets painted on the frame by my dll, and repainted if I move another window with the mouse over it. But if I overlay the window with another one and click on 'minimize' the icon does not get repainted. If I look with spy++ I see WM_ERASEBKGND being fired, my C# PaintExtras method is executed. Any idea how to solve this? I copied the C#-code below. It is a little different then the code I posted a couple of days before.
As a sidequestion: how do I dispose this dll from memory after I have done with it?

Regards,

Stefan.

I've got a little problem... I wrote backup wizard that does the backup and if you selected the send via email option, it sends the files. Now on win98 it backup perfectly except for sending the email, it gives somekind of support error. Is the smtp only supported in 2000 and xp or is there any possible way that it can work in 98?

You might want to tell us what the EXACT error message is. Win98, out of the box, does have any support for a SMTP client. IIRC, the message objects only work on 2000 and above.

Getting xml into objects.

Hello!

I am making a simple php-editor and right now I'm working on the intelliprompt memberlist. It is supposed to show with all the php functions. I then needed to store all the phpfunctions and information about them somehow. I choosed to use an xml file. The xml file looks like this:

<?xml version="1.0" encoding="utf-8" ?>
<FunctionList Language="PHP">
<Functions>
<Function Name="abs" ReturnType="number">
<Parameters>
<Parameter Name="number" Type="mixed" />
</Parameters>
<Description>
<![CDATA[
Returns the absolute value of number. If the argument number is of type float, the return type is also float, otherwise it is integer (as float usually has a bigger value range than integer).
]]>
</Description>
</Function>
<Function Name="acos" ReturnType="float">
<Parameters>
<Parameter Name="arg" Type="float" />
</Parameters>
<Description>
<![CDATA[
Returns the arc cosine of arg in radians. acos() is the complementary function of cos(), which means that a==cos(acos(a)) for every value of a that is within acos()' range.
]]>
</Description>
</Function>
</Functions>
</FunctionList>

And I was wondering whats the best way of looping though every functions element and taking out name, returntype, all the parameters (name, type) and the description and adding it into objects?

I would appreciate a little code examples (they don't have to be complete or working) so I get what you mean.

Thanks in advance!

Search MSDN about XmlSerializer. It can do all that you described and MSDN has plenty of samples of its use.

Hello

I have a database of a library system. I create a report that will display all the overdue books. I have looked at the wizard for creating the reports. But nothing that allows me to do this type of query.

SELECT BookRef, Title, DateDue FROM Book WHERE DateDue < '" + txtCurrentDate.Text + "' ";

But l am not sure how to create a report that will execute this query.

Thanks in advance,

Has anyone figured out how to use NDoc to pull the XML comments out of a web site in 2005? Since they changed the way web projects work (they don't have a project file and you can't set the XML documentation file option), I can't use NDoc to generate documentation. Any ideas?

Searching Rectangle into scanned image

Hi,

Here we are facing problem which i am describing as below.
We are having scanned image but this image is skewed at some angle (we don know the angle) and may be shifted / translated sometimes.Our goal is to find out the Rectangle of predefined height and width by which we can get the 4 end points of Ractangle.Here color of that Rectangle is Pure Black and backggroud color is white.Here we are having only one Regular Rectangle in an image and our image is black and white.
so let's know the methods of finding End point co-ordinate of that Rectangle.

Thanks in Advance.

regards.,

You can add contextMenu...in registry.
In fact you can add menu, button in IE, etc.
