I have problem with calling websevice method Asyncronously using WebService behavior. I can not make more than two request simultaneously to webservice. If I call webservice method 3rd time, it won't event go to web service until response of 1st or 2nd is received.
But if I use the same web service in a windows application using Proxy. I can invoke web service method any number of times Asyncronously without waiting for response for the pervious calls.
Does anyone know why its behaving like this? Is there any way to solve this problem?
Thanks in advance.

Is it possible that the web server only has 2 threads handling requests from users?

The problem is not on the WebService, it's on the client. On the client, check the System.Net.ServicePoint.ConnectionLimit, it defaults to 2. Does this number raises an "A-HA" on you?

Then, why it works with windows application?
How to check ServicePoint.ConnectionLimit in ASP Application ?

Because probably you are passing through a proxy, which only supports HTTP/1.0 forwarding, and in this case, the default connection limit is 4.
Check the documentation for ServicePointManager.DefaultPersistentConnectionLimit and ServicePointManager.DefaultNonPersistentConnectionLimit to see this difference.

Hello,
I had written few articles for a major publishing company which unfortunately went out of business. I put together a website to publish these myself. The code samples are all in C#. Please check it out:

If you want a better reaction then submit them to CP. I have not read them properly yet but from first glance they seem of high quality and would be received well here. Plus you get to say to potential employers "300k CPians say my articles rock"

Yes- Wrox, well I am considering doing it on CodeProject, but the amount of time everybody takes to publish them....I wrote these back in November 2002. Wrox decided to publish them in March and went out of business- anyways, thanks for your feedback I will definitely look into publishing them.

Is it possible to write a trace with a EventLogTraceListener using a level of priority for an event like EventLogEntryType ???
By default using EventogTraceListener write trace event like info Event not like Warning or Error ?

Hello all,
I've made a COM component that uses CryptAcquireContext. When I call it from VB.NET application it works perfectly, but when I try to call it from an ASP.NET web service CryptAcquireContext fails. The error is: "The system cannot find the file specified". How do I fix this error, is there some additional tag to put in Web.config file ?
Thanks in advance

Hi,
I have a major problem in .Net Remoting..
I want to implement a ActiveX Control on Server Side but there seems no way out. Here is how i tried to implement it.
1) Created a form which containd the activex control
2) Implemented by a Class object inheriting System.MarshalByRefObject.
3) Created a instance of form in the class, like:
public class Class1 : System.MarshalByRefObject
{
FormControl fc = new FormControl();
}
and then tried to call it's member function on constructor.
4) on calling this object , from a server component implementing Remoting, it works fine.
5) but the problem comes now.. On implementing the client, a exception is thrown:
Unhandled Exception: System.Reflection.TargetInvocationException: Exception has
been thrown by the target of an invocation. ---> System.Threading.ThreadStateExc
eption: Could not instantiate ActiveX control '11111111-7ba3-1111-9623-1111111
bd0' because the current thread is not in a single-threaded apartment.
Please help me out.

Try putting the following attribute in your client app. Remove the [STAThread] and put [MTAThread].
[MTAThread]
static void Main()
{
Application.Run(new Form1());
}

These two options appear to have no affect on the appearance of status bar panels. Anyone else observed this?

They have an effect on my system (Win2K). Maybe it depends on the oiperating system in use?

Although I have a Win2K system I could test it on, I've never been able to get a .NET application to run on it, even after upgrading to IE 6, installing the latest service packs for a gazzillion things, etc.
I'm using XP and I specified a manifest. Maybe I'll try getting rid of the manifest. I just love the inconsistencies in XP and .NET. 
Thanks for the tip though!

OK, they do not live happily together.
A button with FlatStyle set to FlatStyle.System does not show a bitmap. Setting it to Popup or Flat is OK, but then the transparent background doesn't match the grey sheen color of the other non-bitmapped buttons.
What is a person to do? Maybe I need to play with it some more, but while I do, is there anyone who's fixed this problem?

Are you assigning the bitmap directly to the Image property or using an ImageList (by setting the Button's ImageList and ImageIndex properties)? I've found that if I use the Image property there's no transparent colour, but if I put the bitmap in an ImageList then I can specify the colour to be treated as transparent in the bitmap.
Good luck!

Yes.

OK, I'll give that a try. Good grief.

Is there such a beast? You can create class libraries fairly easy, but is there a .NET equivelant to the old COM .EXE Server?

No.
Here is an excerpt from the regasm.exe implementation :
private void RegisterManagedType(Type type, string strAsmName, string strAsmCodeBase) {
...
local6 = Registry.ClassesRoot.OpenSubKey("CLSID", true).CreateSubKey(local2);
local6.SetValue("", local0);
local7 = local6.CreateSubKey("InprocServer32");
local7.SetValue("", RegistrationServices.strMsCorEEFullFileName);
local7.SetValue("ThreadingModel", "Both");
local7.SetValue("Class", type.FullName);
local7.SetValue("Assembly", strAsmName);
local7.SetValue("RuntimeVersion", local1);
if (strAsmCodeBase != null)
local7.SetValue("CodeBase", strAsmCodeBase);
local7.Close();
if (local3 != String.Empty) {
local8 = local6.CreateSubKey("ProgId");
local8.SetValue("", local3);
local8.Close();
}
local9 = local6.CreateSubKey("Implemented Categories");
local10 = local9.CreateSubKey("{62C8FE65-4EBB-45e7-B440-6E39B2CDBF29}");
local10.Close();
local9.Close();
this.EnsureManagedCategoryExists();
local6.Close();
Even if you tweak the registry keys yourself, it's likely the CCW does not provide the appropriate apartment.

I am trying to get a structure returned from a web service and am having a hell of a time.
I can consume the service through IE and get back my XML package just fine, but when I try the same thing in a Windows Forms client application I get an error that says there is an error in the xml file.
I can return simple types like Booleans and stuff all day in the client but not a publicly declare structure.

Ok, I figured out the problem... Some of my structure members were strings containing text that was encrypted and the chars returned by the encryption function must not be XML friendly.
Any ideas how to escape this?
