I have an example where I have a client and a server. Via remoting I am instantiating a remote object (singleton mode), calling a method on the remote object, which fires an event (using a delegate) back to the client machine. I have created a tcp channel on both the client and the server for bi-directional communication.
If I start the server, then start the client, everything works fine and calls to the server result in an event being fired and sent back to the client.
If I keep the server running, shutdown the client, restart the client listening on the same port, I get the following error:
System.Runtime.Remoting.RemotingException: Requested Service Not Found
I have a feeling this has to do with the remote object lease, but I'm not sure what I need to do in this case.
If anybody could help me, I'd greatly appreciate it.

Howdy...
VB is not my domain -- but I am trying to understand a "problem" I am running into.
I've got this EXE -- written in VB6.
I've got this DLL -- written in C++ (.net 2003) (compiled for UNICODE).
I need to pass UNICODE strings from VB to my C++ DLL. But it seems that the strings are coming across as ANSI strings.
Am I seeing things? I thought VB was UNICODE?
Anyhow -- the external declaration for the DLL function declares every string "as string" -- is there something I can do here to make that better?
I NEED UNICODE.

I'll reply to myself -- since I figured out part of the answer.
It seems that VB6 passes args to other functions as ANSI. And in order to change this I should change how the external args are declared.
Changing "as String" to "as Any" will do it. (This MSDN article refers to this method for calling reg functions with UNICODE).
Great -- now it get's a little more interesting -- I want to return a few strings as a result. The DLL refers to this parameter as "ByRef Ihandle As String" -- will "ByRef IHandle As Any" work? And what will the C++ parameter be? (bstr_t *)?

A BSTR, I would have thought. _bstr_t is a class to convert strings between char * and BSTR for you.
However, the way to find out is to debug and let the IDE tell you.

First, your question belongs in the ASP.NET[^] forum.
Second, IIS doesn't have user groups. Are you talking about Windows Security? Be clear about this when you repost your question in the correct forum.

Thanks for the information. I have deleted this post and have re-worded it for posting in the ASP .NET area.

hi ppl,
i'm lookin for some web application for library system or book keeping.
my boss wants me to develop such a system for the office. does anyone
of you have such a system or can help me in building such a system.
the reason my boss wants it to be a web application because it'll not
be necessary to install the application on each PC. just a simple
link at the internet browser and the application opens up.
But i don't know a single thing about book keeping book management or
library system. if someone of you has such a system or
have developed such a system please be kind enough to help me.
Thanks in advance.

Then I guess you're screwed... No one here is going to just "give" you their code. Especially with a project this big.
If you want a web application like this, buy it off-the-shelf. It'll be cheaper than paying you to write it for the next year. Also, any accounting accuracy liability will be removed from your shoulders if you use a commercial product.

ROTFL - your boss is an idiot. Why would he ask you do to this, if you're not able to do it ? I'd look for another job.
If you know how to program web applications, then you should be able to ask your boss what he wants and write it. If not, then tell him it's not your job to write web applications ( I hope it isn't, if you don't know how ), and that it's cheaper to buy something than to pay your wage while you dither around trying to learn.

hi,
thanx guys for the advices. but tell you christian it'snot that easy to resign and look for another job. but i'll try to do something. and hope things are allright. but even if you guys find something to help please do so.

Not likely. If you know nothing about accounting, it's hopeless...

thanx dave,

Dude - here's the thing. I know it's hard to just quit, I didn't mean that. I'm telling you that if you have no experience in writing web applications, you should look for another job. THEN quit. Obviously, you have bills to pay and so on, but even if you get out of this one alive, your boss will still be an idiot, and will still give you jobs that you're not qualified for, because he can and he's dumb enough to think he'll save money that way.

OK THANKS LETS MAKE IT MORE ELABORATE
COLA COLB COLC
NAME AGE AMT
JOHN 25 500
ROSE 15 1200
RICE 50 500
DICK 70 200
NOW THE COLOMNS ARE COLOMNS ON EXCEL SHEET.THE NAME ON THE WORK SHEET1 IS PEOPLE AND THE SAME NAME EXISTS IN WORK SHEET TWO WITH WORKSHEET NAME AS BUYERS AS BELOW
COLA COLB COLC
NAME PROD LANGUAGE
RICE ORANGE ENGLISH
ROSE EGG FRENCH
DICK PEN GERMAN
JOHN BOOKS GERMAN
AN EXAMPLE OF MY OUTPUT FOR JOHN SHOULD BE ON TWO SHEEETS.THE PEOPLE SHEET AND THE BUYERS SHEET. LIKE BELOW
COLA COLB COLC
NAME AGE AMT
JOHN 25 500
15 1200
50 500
70 200
AND ON SHEET2(BUYERS)
COLA COLB COLC
NAME PROD LANGUAGE
ORANGE ENGLISH
EGG FRENCH
PEN GERMAN
JOHN BOOKS GERMAN
FROM THIS OUTPUT YOU CAN SEE THAT ALL OTHER NAMES ARE CLEARED AND JOHN STILL MAINTAINS ITS POSITION ON THE TABLE ON BOTH SHEETS.ALL OTHER NAMES ARE CLEARED SO THAT NO ONE COULD HAVE AN IDEA OF WHO OWNS THE VALUES.THIS MEANS THAT THE MACRO CODES SHOULD BE ABLE TO IDENTIFY THE NAME ON SHEET ONE , PICK IT,CLEAR THE OTHERS, AND GOTO SHEET 2, PICK THE SAME NAME, AND CLEAR THE OTHERS THEN SAVE THE SHEET FOR EACH PERSONS BY THEIR NAMES.THIS MEANS 4 SAVED SHEETS AND ON EACH IT SHOULD ONLY SHOW THE NAME OF THE PERSON IN QUESTION.
ALSO I NEED A CODE THAT WOULD CONVERT MY EXCEL SHEET TO PDF.CAN ANYONE PLS HELP ME?

First, STOP YELLING!
Second, do your own homework. We will not write your code for you. We will help you with your code, though, but you have to at least try to write it first.
Third, you'll need a third party component to convert, or print, the sheet into a .PDF file.

One of those can even be found here on CodeProject. Try the search thingy at the top.

Yeah, but the OP doesn't get an email that says you added this little tidbit. Only I get that notification.

Sorry, I've never used PDFDistiller. We can't possibly support the thousands of 3rd party libraries out there because there are so many of them.

The following VB example convert "c:\*.xls" to pdf file, not include file of sub-folder, the conversion result is in "d:\":
dim ConvertCom as object
dim sResult as string
set ConvertCom=CreateObject("czxls2pdf.ConvertApplication")
ConvertCom.Visible=true
sResult=ConvertCom.ConvertFolder("c:\*.xls","d:\",false,"")
if sResult="" then
msgbox "Convert OK!"
else
msgbox "Convert Failure, error reason is" & sResult
end if
set ConvertCom=nothing

so how do i get the third component? i need to get this resolved pls advice me on what to do.

It's called a 3rd PARTY component. It means that someone else besides you or Microsoft wrote it. A 3rd party/person wrote the component.
Google for PDF writer! You'll find dozens of them. One here on CP, a bunch over on SourceForge, ...
But in ALL cases, YOU have to learn how to use the component.
