strange problem with webservice

We use the new Asynchronous Agents Library in Visual C++ 2010 to solve the classic Dining Philosophers concurrency problem.Rick MolloyMSDN Magazine June 2009

State management in Web applications is a contentious issue. Should you store user data per session or should you persist it across sessions? You can easily store information temporarily while someone navigates your site by using session state. Fritz OnionMSDN Magazine April 2006

Hi,I have an ASP .NET 2.0 web application. I used VB .Net to implement and the DB is in Microsoft SQL Sever 2000. After I published it to the production severs, I encountered a problem. Several times, the site just kind of crashed. No any error pages. Basically, everytime, the site was working fast and good at the beginning. After completing several forms, it suddently takes forever to response to another user's action, like button clicking... It looks like the DB connection is suddenly broken for a while. I checked the Event Log, i didn't see anything wrong. But after a while, it starts to work fine again. Does anyone have any suggestions? thanks

Hi, I have a hosting plan with .NET 2.0, 3.0, 3.5
Windows Server 2008 / IIS 7.0. I made a project in asp.net (net 2.0) but when i upload it to my hosting plan I always get this error message:

500 - Internal server error.
There is a problem with the resource you are looking for, and it cannot be displayed.

I removed web.config file from my directory and start getting the main page of my website but when i click on the button (asp.net button which verifies the password from the database after taking it from a checkbox) i get the following error message.
Server Error in '/' Application.


Runtime Error




Description: An
application error occurred on the server. The current custom error
settings for this application prevent the details of the application
error from being viewed remotely (for security reasons). It could,
however, be viewed by browsers running on the local server machine.

Details: To enable the
details of this specific error message to be viewable on remote
machines, please create a <customErrors> tag within a
"web.config" configuration file located in the root directory of the
current web application. This <customErrors> tag should then have
its "mode" attribute set to "Off".







<!-- Web.Config Configuration File --><configuration> <system.web> <customErrors mode="Off"/> </system.web></configuration>






Notes:
The current error page you are seeing can be replaced by a custom error
page by modifying the "defaultRedirect" attribute of the application's
<customErrors> configuration tag to point to a custom error page
URL.

Hi, Assume drawing a house on the lower left corner of one form:
protected override void OnPaint(PaintEventArgs e)
{
float zoom = 1F;

e.Graphics.Transform = new System.Drawing.Drawing2D.Matrix(
new System.Drawing.RectangleF(0, 0, Width, Height),
new System.Drawing.PointF[]{
new System.Drawing.PointF(0,Height/zoom),
new System.Drawing.PointF(Width/zoom,Height/zoom),
new System.Drawing.PointF(0,0)});

Pen p = new Pen(Color.Black, 1);
e.Graphics.DrawLine(p, 0, 0, 100, 0);
e.Graphics.DrawLine(p, 100, 0, 100, 100);
e.Graphics.DrawLine(p, 100, 100, 0, 100);
e.Graphics.DrawLine(p, 0, 100, 0, 0);
e.Graphics.DrawLine(p, 0, 100, 50, 150);
e.Graphics.DrawLine(p, 50, 150, 100, 100);
}


My problem is that with this transformation some parts of that house will disappear. And if I set zoom to something other than 1, the house will move on the form. Can anybody please say where is my fault?
