Dear All
i am migrating vb project to .net to create web based CRM .
In that VB Projetct one active x control is used which is exclusively made for
windows application I am developing the .net project using web Servises
That active x control use dial method to make a call from agent desktop to client's mobile
also OtherPartydisconnected,thisPartydisconnected otherpartyAnswered and thisPartyanswered these
events of that active x control is required
Please suggest me how i can achive to write these Events in Web Service.
Please Gude me in this Regards.
Thanks to all

It may not be possible for you to use this component in a Web Service. Web Service code runs entirely server-side, and depending on the speed at which this AxtiveX module does it's work, you may not be able to use this component in a web service, or it may not be the best choice for using it.
Depending on the component and exactly what it does, you may have to implement the functionality around this component in a Windows Service instead. This service would probably have to setup some queue to receive it's work orders and service these orders, one at a time, until the queue is empty.

Dave, Thanks For your Reply.
Basically Events OtherPartyDisconnected ThisPartyDisconnects are fired by CTC SERVER
I am not intrested to use the active x control basically this active x control,
call its MakeDial Method and when when party get disconnects that time on my crm the Hang up button get activated. From my CRM the agent from his desktop phone which is connected through
EPBX i want to call the customer. and when customer disonnect then i want to activate Hang UP Button on my CRM Basically this is a outbound crm i am developing.
So will it possible to write the functionalty through Web Services.
Thanks

It's not possible like you described, IF I understood your description. Web Services exist for a very short time and do not hold session state. What you're decribing requires a very long object lifetime and maintain session. This would be better served by either a Windows Service or directly in your application.

As known in MFC, thread function must be a static function because non-static function contains a 'this' pointer.
But this is not a problem at all in .net, I want to know how CLR can do that?
Thanks.

The only reason the function needs to be static in MFC is because of the underlying APIs used.
Since the underlying APIs use a C interface, they no nothing of C++ class objects and the
associated this pointer.
The .NET framework already knows there's a managed object involved. The framework is designed for
language independence so the interface is well defined.

Technically what it does for a delegate to a non-static method is to generate a small thunk containing a pointer to the object and a pointer to the method. The thunk contains code which calls the method, passing the object pointer as a parameter, just as an instance method call normally would.
In C++ I normally write
static DWORD WINAPI CMyClass::ThreadStartProc( LPVOID pvParam )
{
CMyClass* pThis = (CMyClass*) pvParam;
return pThis->ThreadProc();
}
DWORD CMyClass::ThreadProc()
{
return 0;
}
_beginthreadex( ThreadStartProc, 0, this );The Framework is just doing this behind-the-scenes rather than you having to spell it out.

It's so funny.
Actually I use the similar MFC codes with your's like this:
<br />
static DWORD WINAPI CMyClass::ThreadStartProc( LPVOID pvParam )<br />
{ <br />
CMyClass* pThis = (CMyClass*) pvParam; <br />
<br />
pThis->MethodA(...);<br />
<br />
pThis->MemberB++;<br />
<br />
return 0;<br />
}<br />
Obviously, your codes is better...

Hello.
Im doing a client server program where the client program is created using Visual C++.NET meanwhile the server program is created using C#.NET. Just for my own knowledge, can both of these program be connected via a network using TCP protocol. I tried to execute the sample. there was no error but it could not be connected. Which part that must i edit? Is it ok if i only edit the client part (created using C++). This is because the server part also have multithreading mechanism, so i dont want to mess that up. For your information, i tried to connect both client and server using port 5000. I will also include here the connection part of the client and server source code. Did i miss anything in the source code in the code snippet attachment? Thank you and your help is very appreciated.
<br />
<br />
<br />
<br />
InitWSA();<br />
<br />
sock = socket(AF_INET, SOCK_STREAM, 0);<br />
if (sock < 0) {<br />
printf("Error no %d occured when creating socket\n", errno);<br />
exit(-1);<br />
}<br />
<br />
myaddr.sin_family = AF_INET;<br />
myaddr.sin_port = 5001;<br />
myaddr.sin_addr.s_addr = INADDR_ANY;<br />
<br />
status = bind(sock, (struct sockaddr *)&myaddr, sizeof(struct sockaddr));<br />
if(status < 0) {<br />
printf("Error no %d occured when binding\n", errno);<br />
exit(-1);<br />
}<br />
<br />
<br />
receiver.sin_family = AF_INET;<br />
receiver.sin_port = 5000;<br />
receiver.sin_addr.s_addr = inet_addr("127.0.0.1");<br />
<br />
status = connect(sock, (struct sockaddr *)&receiver, sizeof(struct sockaddr));<br />
if (status < 0) {<br />
printf("Cannot connect to server, error no %d occured\n", errno);
exit(-1);<br />
}<br />
<br />
<br />
<br />
<br />
<br />
string portStr = textBoxPort.Text;
int port = System.Convert.ToInt32(portStr);<br />
<br />

IPEndPoint ipLocal = new IPEndPoint (IPAddress.Any, port);<br />

Maybe try NOT binding the client socket - let the protocol pick the socket name.
You should be able to debug this easily.
What calls are failing?
On the client, I don't see any code that checks error codes returned from failed socket API calls
Shouldn't you be using WSAGetLastError instead of errno?

hello and thanks for the reply
I tried the method you said. So I disable the binding socket. Still, the client could not connect to the server. Actually, there is no error in the code but it just could not connect the client which is programmed in C meanwhile the server side is programmed using C#. So i think it is not about the errno or the WSAGetLastError problem. Actually, this is just only a test program. After i proved that it can connect, then I will produce a real version. I just want to know is there any method or code which can connect a client programmed in C to a server which is programmed in C#. I assume that the connect() call failed since the printf("Cannot connect to server, error no %d occured\n", errno); as in the code snippet will be displayed. So this clearly means that it just could not connect to the server. Anyway, thank for your reply and help. Any other idea's or solution? hehe..

TCP/IP is TCP/IP, no matter what platform it runs on or what language the code is written in.
Why do you dismiss error codes? They can give you important clues to reasons for failure.
That's why they are there. Why not use the clues the system offers? Otherwise all you can do is guess.
Using the socket APIs properly will help...
First you need the port number in network byte order:
receiver.sin_port = <span style="font-weight: bold;">htons(5000)</span>;
Then you need to properly check for errors:
status = connect(sock, (struct sockaddr *)&receiver, sizeof(struct sockaddr));<br />
<br />
if (<span style="font-weight: bold;">SOCKET_ERROR</span> == status)<br />
{<br />
printf("Cannot connect to server, error no %d occured\n", ::WSAGetLastError());
<br />
}<br />

hello mark
Thanks for the reply. I just add the byte order method htons and it works. Thanks for the solution. I really2 appreciated it. Also thanks for the tips to take error messages seriously. I will take your advice. I know error messages is important for debugging, but i just consider a simple connection from client/server, thats why i dont want to concern the error messages. I will be careful next time. Thanks again.

Hi,
1.
have a Windows.Forms.Timer tick at the required frequency; in its Tick handler:
2.
modify the text you want to show, and cause a repaint.
say you are using a Label, just set the new string value in label.Text
say you are drawing the string yourself in a Panel's OnPaint method, call panel.Invalidate().
etc.

I created an Service and when i tried installing it to Services through dos I get the following error.
"No public installers with the RunInstallerAttribute.Yes attribute could be found..."
any ideas on sorting this out?

You don't have this:
[RunInstaller(true)] <--------------------
public partial class MyInstaller : Installer
and your installer class has to be public.

Hi,
I have added an column to the typed dataset from .xsd file schema. But when i check it in the debug mode, I see that column field mapping for 2-3 has been mismatched.
What order do I need to add the field in to the .xsd schema file?
I possible can any body let me know the process to add an column in existing typed dataset?
Regards,

I've written an assembly (.Net 2.0 DLL in C#) that streams a FLV video file to a flash player contained in the same program. Due to the nature of the FLV file, I have to load it in small chunks and pass the chunks in the stream one at a time. This works pretty well. However...
Under Vista (not SP1), as the file is streamed, memory consumption creeps up and up and up, and even after the stream has been closed, the memory consumption keeps increasing until the program itself is shutdown. Under XP, this does not happen at all. We have almost verified that the flash player is probably the culprit, but we don't know what to do about it.
We've tried streaming larger and smaller blocks of data, we've completely re-written the threading code twice, and we've tried several methods for actually streaming the data.
Can anyone offer any advice or pointers? Something to look for?

How are you accurately checking memory usage?
Vista caches memory much different than previous operating systems.
Vista will happily use up all the RAM before dropping it for other processes to use.
Of course, there very well could be a bug in the player

Well, it's not real scientific - we use Task Manager.
Yeah, I'm aware that Vista uses memory differently, but the behavior I've described starts to adversely affect the program's performance because eventually, Vista starts paging to disk to accommodate it's "caching" mechanism. On REALLY long videos (we're talking 1gb or more) the video develops a real bad stutter, and any system performance that escapes Vista's resource usage essentially disappears.
To read a block of the file at a time, I allocate an array of bytes before the loop, and I re-use that array until the operation is done. To make sure we didn't have a leak in the loop code, we simply stopped streaming what we were reading, and just let the loop load block after block of data. The memory use didn't go up at all at that point. This tells me that the problem is in the player. However, we don't have the source to the player itself. I think it's Adobe's component, but I'm not sure. I did the encryption and file streaming part of the app and haven't had to deal with "the other end" of things.
Is there a utility that will track memory usage better than Task Manager?
