Creating publisher policies for DLLs
We have a .NET dll that we are deploying to our customers using a deployment
project in VS .NET 2003. There is a lot of information about creating
publisher policies on the web, but we have not been successful in creating
one. Here's what the ultimate goal is:
When the DLL is deployed to a customer's system, every application using
this dll must point to the new version. This has to be an automated process
using the deployment project.
This is what we have already done:
1. Created a file called app.config with the following text:
<configuration>
<runtime>
<assemblyBinding>
<dependentAssembly>
<assemblyIdentity name="name of assembly"
publicKeyToken="public key token"
culture="en-us"/>
<bindingRedirect
oldVersion="1.0.0.0-65535.35535.65535.65535"
newVersion="2.0.1.0"/>
<codeBase version="2.0.0.0"
href="http://www.foo.com/bar.dll"/>
</dependentAssembly>
</assemblyBinding>
</runtime>
</configuration>
We copied this from a howto on gotdotnet.com
2. We signed the dll with our key and created a policy file.
3. We then deployed this dll to the customer's GAC.
However, the customer's application that used an old version of the dll did
not automatically redirect to the new version.
Is there something we are missing?
Does the name of the config file have to be something specific (like
myassembly.dll.config)?
Has anybody ever gotten this to work?
Any help would be appreciated,
Thanks,

ServicedComponents built on 1.1 to be usable on 1.0
Hi group
I have created a class library that has a class that inherits from
ServicedComponents. I have .Net Framework 1.1 installed on mu machine.
I build the application and was able register it using regsvcs.
I have to deploy this application on a machine that has only .NET
Framework 1.0 installed. After a lot of search I could create an
application config file that has the bindingredirect for nearly all
the .NET assebblies.
After I build and try to register it on that server I am getting an
error stating ..
"System.IO .... unable to find the assembly or some assembly that is
used."
If I dont inherit my class from servicedcomponents and try to use it
in another exe and run that exe on the server machine it gives no
error.
Where am I going wrong? Any help is appreciated.

MS Outlook automation from .NET Windows Service
Hi, All!
I seem to be having something of an Outlook automation problem, and if you guys could please be bothered to take a look at the following snippet of C# code:
static void TestOutlookAutomation()
{
System.Diagnostics.EventLog tmpEventLog = new EventLog("Application");
tmpEventLog.Source = "Test Outlook Automation Client";
try
{
tmpEventLog.WriteEntry("Starting Outlook Automation", EventLogEntryType.Information);
Outlook.Application olApp = new Outlook.ApplicationClass();
Outlook.NameSpace olNs = olApp.GetNamespace("MAPI");
for (int k=1; k<=olNs.Folders.Count; k++)
{
Outlook.MAPIFolder folder = olNs.Folders.Item(k);
printFolderInfo(folder, 0);
}
}
catch(System.Exception eX)
{
string msg = "";
System.Exception traceEx = eX;
while (traceEx!= null)
{
msg += traceEx.GetType().ToString() + ": " + traceEx.Message + "\n";
traceEx = traceEx.InnerException;
}
tmpEventLog.WriteEntry(msg, EventLogEntryType.Error);
}
}
public static void printFolderInfo(Outlook.MAPIFolder folder, int level)
{
string tabs = "";
for (int i=0;i< level; i++)
{
tabs += "---";
}
System.Diagnostics.EventLog tmpEventLog = new EventLog("Application");
tmpEventLog.Source = "Test Outlook Automation Client";
tmpEventLog.WriteEntry(tabs + folder.Name + "\t(" + folder.Items.Count + ")", EventLogEntryType.Information);
for (int j = 1; j < folder.Folders.Count; j++)
{
printFolderInfo(folder.Folders.Item(j), level + 1);
}
}
For testing purposes I've wrapped these two methods inside a) a Windows Service Project, and b) a standard Windows Application Projects, built them and deployed the assemblies on two different computers - both having MS Outlook installed, both running Windows 2000 OS -. However, on computer1 the Windows Service, as well as the standard Windows App, runs smoothly. On computer2, on the other hand, the Windows App reads the mailfolder info with no problem whatsoever, but the execution of the Windows Service results in a System.Runtime.InteropServices.ComException error message being written to the eventlog. This, despite the fact that the owner of the process in which the Windows Service and the standard Windows App executes on computer2, is the exact same Windows user profile.
Any advice on this issue would be highly appreciated.

.Net ViewState toggle causing Smurf Attack in routers ?
Our .NET web application was getting blocked in several routers (DLink) as a "Smurf Attack" (a faked sender
IP address). This was systematically happening in the transfer between the first and the second page on our
web site
After much ado we found out that turning off client viewstate (in the Aspx page) caused the problem to go
away; or so we thought. it turns out we only moved the problem a couple of pages later in the system, but
this time it was a HttpHandler that was being blocked (no Aspx involved)
Before we got the second bug report, I thought this problem was related to the actual _VIEWSTATE HTML hidden
field that was being sent. When the second problem was reported, I am more inclined to believe that the
ViewState toggle (in the Aspx) has some side-effect on Socket Pooling in IIS/.NET. Between the two page
requests, there is idle time on the socket (obviously, we are waiting for user action); could the Smurf
Attack be triggered by a change of socket for the next request ? Anyone have any experience on this

Byte array to string and back - newbie question
Hi,
I am trying to implement DES algorithm as described in the Microsoft article at
http://msdn.microsoft.com/library/en-us/dnnetsec/html/SecNetHT10.asp.
The problem is that I need to save the data in the database as String, and for that I have to convet from Byte array to string and back.
When I cast a byte array into a string and then back to a byte array, I don't get the same array. For example:
Dim SecretText As Byte()
Dim SecretText1 As Byte()
Dim Text as string
.....
SecretText = enc.Encrypt(Data, Key, Vector) 'returns Byte Array
Text = Encoding.ASCII.GetString(SecretText) 'convert to string in order to save into the DB
....
....
....
SecretText1 = Encoding.ASCII.GetBytes(Text) 'prepare for decryption routine
At the end, SecretText1 does NOT equal to SecretText, and I want it to be. How should I do the conversion correctly?
Thanks!!!

MSN Presence info
Originally posted to microsoft.public.dotnet.framework.aspnet with no
viable responses:
1st, if this is the wrong group, let me know... my local
server doesn't carry the full feed from MS.
After spending about 2 hours searching (google, codeproject,
sourceforge.. etc), I've not been able to find an example of code that
will allow you to publish your MSN status. I did find some older
examples, but apparently there have been some changes in protocol and
they are no longer valid.
Does anyone know how to go about doing this, or have a link to
somewhere that does?
I did find an article that went into a little detail about the
protocol, but it was more geared towards "this is how you sign on and
send a message". I even started scouring MS for some kind of SDK
(Although by the time I thought of that my brain was starting to
hurt).
One would think that MS would supply a simple URL as some of the other
messenger services do.. but I can also see the cost of doing that in
server usage and bandwidth. I guess the only way would be to develop a
control that pretends to be a client and check that way.... sheesh. Tag: Start another program Tag: 68518
TURN $12 INTO $12,000 NOW!!!
EEP THIS SHIT YALL MY FRIEND GOT $500 LAST WEEK TRYING THIS SHIT:
make extra cash
GREAT WAY TO BECOME RICH...INSTANT THOUSANDS This is no scam, read
it!!!!!!
------------------------------------------------------------------------
-------- HOW TO TURN $12 INTO $12,000!!!!!!!!!!!!!!!!!!!!!!!!!!!! THIS
REALLY CAN MAKE YOU EASY MONEY!! IT WORKS !!! BUT YOU HAVE TO FOLLOW IT
TO THE LETTER FOR IT TO WORK!!!! : A little while back, I was browsing
through newsgroup, just like you are now and came across an article
similar to this that said you could make thousands dollars within weeks
with only an initial investment of $12.00! So I thought, "Yeah, right,
this must be a scam", but like most of us, I was curious, so I kept
reading. : Anyway, it said that you send $2.00 to each of the 6 names
and address stated in the article. You then place your own name and
address in the bottom of the list at #6, and post the article in at
least 200 newsgroup. (There are thousands) No catch, that was it. So
after thinking it over, and talking to few people first, I thought about
trying it. I figured what have I got to lose except 6 stamps and $12.00,
right? Like most of us I was a little skeptical and a little worried
about the legal aspects of it : All, So I checked it out with the U.S.
Post Office (1-800-725-2161) and they confirmed that it is indeed legal!
Then I invested the measly $12.00. Well GUESS WHAT!!?. Within 7 days, I
started getting money in the mail! I was shocked! I figured it would end
soon, but the money just kept coming in. In my first week, I made about
$25.00. By the end second week I had made a total over $1,000.00! In the
third week I had over $10,000.00 and it's still growing. This is now my
fourth week and I have made a total of just over $42,000.00 and it's
still coming in rapidly. Its : Certainly worth $12.00, and 6 stamps, I
have spent more than that on the lottery!! : Let me tell you how this
works and most importantly, why it works?.also, make sure you print a
copy of this article NOW, so you can get the information off of it as
you need it. STEP 1: Get 6 separate pieces of paper and write the
following on each piece of paper "PLEASE PUT ME ON YOUR MAILING LIST."
Now get 2 US $1.00 bills and place TWO inside EACH of the 6 pieces of
paper so the bills will not be seen through the envelope to prevent
thievery. Next, place one paper in each stating the above phrase, your
name and address, and 2 $1.00 bills. What you are doing is creating a
service by this. THIS IS ABSOLUTELY LEGAL! Mail the 6 envelopes to the
following addresses:
#1) Corteney Tomson P.O. Box 55 Dupo, IL 62239
#2) Brad Taylor 6 Terry Ln. Hutchinson, KS 67501
#3) Cedric Etienne 239 Autumn Breeze Way Winter Park, FL 32792
#4) Stephen Mitchell 1977 Alcovy Trace Way Lawrenceville, GA 30045
#5) Melissa Martinez 15440 sw 74 cir ct #607 Miami, FL 33193
#6) Maurice Sawyers 49 Middle Rose St Trenton, NJ 08618
STEP 2: Now take the #1 name off the list that you see above, move the
other names up (6 becomes 5, 5 becomes 4, etc?.) and add YOUR Name as
number 6 on the list. STEP 3: Change anything you need to, but try to
keep this article as close to original as possible. Now, post your
amended article to at least 200 newsgroups, message board. (I think
there are close to 24,000 groups) All you need is 200, but remember, the
more you post, the more money you make!---- DIRECTIONS----HOW TO POST TO
NEWSGROUPS, MESSAGE BOARD----------Step 1) You do not need to re-type
this entire letter to do your own posting. Simply put your cursor at the
beginning of this letter and drag your : Cursor to the bottom of this
document, and select 'copy' from the edit menu. This will copy the
entire letter into the computer memory. Step 2) Open a blank 'notepad'
file and place your cursor at the top of the blank page. From the
'edit' menu select 'paste'. This will paste a copy of the letter into
notepad so that you can add your name to the list. Step 3) save your new
notepad file as a .txt file. If you want to do your postings in
different sittings, you'll always have this file to go back to. : Step
4) Use Netscape or Internet explorer and try searching for various
newsgroups (on-line forums, message boards, chat sites, discussions.)
Just example you log on any search engine like yahoo. com,google.
com,altavista. com,excite. com then you search with this subject ?
millionaire message board? or ?money making message board? or ?
employment message board? or ?money making discussions? or ?money making
forum? or ?business message board? etc. You will find thousand &
thousand message board. Click one by one then you will find the option
post a new message. : Step 5) Visit these message boards and post this
article as a new message by highlighting the text of this letter and
selecting paste from the edit menu. Fill in the Subject, this will be
the header that everyone sees as they scroll through the list of
postings in a particular group, click the post message button. You're
done with your first one!. : Congratulations? THAT'S IT! All you have to
do is jump to different newsgroups and post away, after you get the hang
of it, and it will take about 30 seconds for each newsgroup! **
REMEMBER, THE MORE NEWSGROUPS OR MESSAGE BOARD YOU POST IN, THE MORE
MONEY YOU EILL MAKE!! BUT YOU HAVE TO POST A MINIMUM OF 200** That's it!
You will begin receiving money from around the world within days! You
may eventually can rent a P.O. Box due to the large amount of mail you
will receive. If you wish to stay anonymous, you can invent a name to
use, as long as the postman will deliver it. **JUST MAKE SURE ALL THE
ADDRESSES ARE CORRECT. ** : Now the WHY part: Out of 200 postings, say I
receive only 5 replies (a very low example). So then I Made $5.00 with
my name at #6 on the letter. Now, each of the 5 persons who just sent me
$2.00 make the MINIMUM 200 postings, each with my name at #5 and only 5
persons respond to each of the original 5, that is another $25.00 for
me, now those 25 each make 200 MINIMUM posts with my name at #4 and only
5 replies each, I will bring in an additional :$125.00! Now, those 125
persons turn around and post the MINIMUM 200 with my name at #3 and only
receive 5 replies each, I will make an additional $625.00! OK, now here
is the fun part, each of those 625 persons post a MINIMUM 200 letters
with my name at #2 and they only receive 5 replies, that just made me
$3,125.00!!! Those 3,125 persons will all deliver this message to 200
newsgroups with my name at #1 and if still 5 persons per 200 newsgroups
react I will receive $15,625.00! With an original investment of only
$12.00! AMAZING! When your name is no longer on the list, you just take
latest posting in the newsgroups, and send out another $12.00 to names
on the list, putting your name at number 6 again. And start posting
again. The thing to remember is, do you realize that thousands of people
all over the world are joining the internet and reading these articles
everyday, JUST LIKE YOU are now!! So can you afford $12.. and see if it
really works?? I think so? People have said, 'what if the plan is played
out and no one sends you: the money? So what are the chances of that
happening when there are tons of new honest users and new honest people
who are joining the internet and newsgroups everyday and are willing to
give it a try? Estimates are at 20,000 to 50,000 new users, every day,
with thousands of those joining the actual Internet.

Slow TCP connection from IE
I have a problem with TCP connections from controls embedded in HTML pages.
The client-application is a (.NET) usercontrol embedded in an HTML page (viewed using IE).
When the client calls:
Dim client As New System.Net.Sockets.TcpClient(_hostname, _port)
while at the same time the server calls:
i = stream.Read(bytes, 0, bytes.Length)
it takes _exactly_ 100 seconds the first time â?? subsequent calls are immediate.
It looks like itâ??s a timeout â?? but of what?!? â?? after all: I get the correct result; no problem there. Using TDImon fra SysInternals I can se that at the first (and very slow) communication, IE initially communicates at port 80 - but I havn't got a clue why. I have wondered whether it could be a DNS error, but the host I communicate to is localhost so I think that would be a rather strange reason. The problem has been verified in different organisations using several independently installed PC's.
When the client control is placed in a winform instead of in a HTML page, there is no performance problem at all.
I have a small, clean and to the point VS-solution which demonstrates the problem if anybody is interested. It consists of the control project, a winforms client, a html page and a tcp-server project.
I am sure that this is expected behaviour â?? just no for me or anyone that has looked at itâ?¦ ;^(

Mutex and WAIT_ABANDONED
.Net's Mutex object seems to ignore (or internally consume) a WAIT_ABANDONED
condition if the owning thread is aborted. The next thread waiting on the
Mutex gets the mutex with no error. If this is by design, it would seem to
be a dangerous design choice. Normally another thread would want to know
this information as the thing the mutex was protecting could (and probably
is) be in an inconsistant state, yet the 2nd thread will march on like
nothing was wrong. Am I missing something?

.NET application memory usage
Has anyone encountered a situation where a .NET(VB.NET) application uses a
lot more RAM on one machine than it does on another machine?
On an machine with XP Pro, .NET Framework 1.1 & all the latest patches my
program uses 45MB of physical RAM and 85MB of virtual memory. This is a LOT
for what this application does. On another machine with Windows 2000
Server, .NET Framework 1.1 & all fixes, the exact same build of the program
uses only 16MB of physical RAM and only 8MB of virtual memory. Simlilarily,
on another XP Pro machine the same build of the program uses about the same
16MB of ram and the same amount of VRAM.
Both XP machines have Visual Studio .NET 2003 installed, and the 2000 Server
doesn't, so this can't be a debug version of the runtime(if there is such a
thing) causing it to use so much RAM.
The program is compiled as release by the computer using so much RAM in all
test runs on each machine.
So... What's going on that causes it to use so much memory on the one
machine but not the other machines?

How to trigger IDE code generation?
Hello all
I am writing a custom formatter to serialize controls to a text file. It largely works (at least I keep thinking that)
My current problem is that when a form is deserialized in the designer, the screen is updated properly and the properties show correctly in the editor window, but the newly altered properties do not persist into code. Usually I need to make a slight modification to the objects (e.g. select and move them) for the alterations to persist
I am wondering is there a simple call which will cause the IDE to initiate serialization to code? I suspect I need to somehow get a hold of the IDE's IDesignerSerializationManager object and through it obtain the necessary serializer for my root object and then serialize it - but how do I do that
Thanks for all replies

Image->Bitmap->Icon transparency problem
Hi,
I'm loading an Icon from a Stream and want to save it to file. I've
realized that in order to avoid a bug in the framework I need to do
something like this:
Bitmap bmp = new Bitmap(m_Img);
IntPtr hdl = bmp.GetHicon();
Icon icn = Icon.FromHandle(hdl);
using (FileStream fs = new FileStream(name, System.IO.FileMode.Create))
{ icn.Save(fs); }
DestroyIcon(hdl);
That works fine, kinda... During the conversions I loose the transparency
of the original Icon; ie. the saved icons will have black backgrounds
instead of transparent backgrounds.
Any workaround? (apart from doing it all through API-calls to GDI+)
Any official acknowledgement from MS about the bug? (a link perhaps)

embedded winforms in IE wont cache
I have a problem. The issue is that my embedded winforms in IE will not cache no matter how hard i try. They seem to goto the download assembly cache but they dont load from there like the framework documentation has stated. I have tried versioning, strong naming, and everything else i can think of.
Any response, esspecially from MS would be great! I would like to know if this is a bug that is expected to be fixed in the .NetFramework, or is there a work around till the bug gets fixed.
Thanks!!!!! :)
Here is some of the previous posting that i had made, followed by MS Response ****:
Hi Bryan,
It's really good to hear someone having the same problem (sorry to say) - precisely the same problem is KILLING my released
application stone dead because of performance issues over low bandwidth connections. I AGREE, the controls are NOT being
loaded from the download cache when available, and the documentation (I am certain) INCORRECTLY says this will happen. I
have based many months of development based on this concept, believing the documentation and suspecting it is me misreading
the signs or doing something wrong. I now no longer believe this to be the case. Can someone out there at Microsoft help?
This is a real cry for help you're hearing here. Why are IE hosted controls not being loaded from the download cache when
no newer versions are available on the server?
Please find attached similar posting (unanswered) from myself on the sister windowsforms.controls newsgroup:
Subject: IE hosted control and the download cache 1/16/2004 3:47 AM PST
Hi,
Should my IE hosted Windows Control be invoked from the download cache after it's first use?
It appears that my Windows Control is being downloaded every time from the Web Server. My understanding is that every time
a Windows Control is invoked from within an HTML <Object> tag, that the CLR first checks on the server to see if there is a
new version of the assembly is available. If there is not, then the last downloaded assembly will be invoked from the
download cache, if one exists. However, it appears that my control is being download every time, and as available bandwidth
narrows, the control takes a REALLY long time to download/invoke, even though I told my managers (perhaps mistakenly!) that
they will only experience this the first time they invoke a new version of the component from the web server.
I had read that there may be a connection between strong naming an assembly and the download cache, so that versioning can
work correctly, however I've just added a stong name to my assembly (by adding [assembly: AssemblyKeyFile(@"....snk")] to
AssemblyInfo.cs) but it appears to have made no difference.
Should I be doing more to get my control invoked from a users download cache whenever possible?
Many thanks,
Richard Sheridan

multiple versions of your assembly there. If they list (0.0.0.0) as the

your assembly:

InvokeAsync on a control until the window handle has been created".
If I copy that part of code back to a form generated by the form
designer, everything works fine. Trying to expand my class to be a form
failed.
Does anyone know what I have to do to get it to work in a control class?
Thanks in advance!

show a new control outside of its parent
I am programming a control for the CF, and i need to make something like the
ComboBox enroll behavior.
If you click on it. it should enroll another item, for example a picturebox.
To enroll it down, it could be possible to define the picture box inside the
control, and on cliking the control to change its clientsize to make the
picturebox visible. But if the control shall enroll it to the top, because
its on the bottom of the form, I would have to change its location and the
size.
the original combobox shows the new item, without changing its size and
location.
So my question is how to show a new control outside of its parent ?
somebody knows help ?

New MS Authorization and Profiler Application Block fits only for small applications and examples!!
Hi to all .NET gurus,
we evaluated the new Application Block "Authorization and Profiler
Application Block" for using with role based authorization.
Our results:
- No roles in roles can be managed (that is a must in a role based
system)
- In every check there is no caching between them (performance sucks)
- Dynamic object creation in every access (performance sucks)
- Profiles and Principals must be handled completely seperated (??)
- In every access check you have to build up parameters etc - this
handling is
unbelievable overhead!!
- You have to cast the principal for every access (you better use a
gerneric
class with static helpers here!)
So the result is: Use it to play a bit and use it for very small
example applications. It is a good example for newbies out there - and
the pluggable system in this block was a good idea (not new but fine)!
I work for companies like BASF, DaimlerChrysler, BMW etc. and i have
implemented some role based access systems before in .NET - but this
block doesn't fit for them.
I can't understand why they did not optimize it - other blocks have
caching etc. in it?
You can implement own providers etc. but thats somewhat dumb that you
better build up your own system with caching, expirations etc...
Let me know if there are questions - i develop open source software
and im .NET consultant for different companies out there.
Greetings and happy programming

Getting error AL1057 at linkage time??
Hi everybody!
I have a Managed C++ application that I have localized with one extra language apart from the default
language. The program now handles culture neutral languages Swedish (default) and English. This is a customized installation tool, so the default is to install things. Localization for that functionality are handled by the Forms own embedded localization. For the Uninstallation functionality I have added 2 resource files (Assembly Resource .resx) named Tool.en.resx and Tool.resx to handle all messages when the uninstall is run. It works fine!!
Now to the problem!!
When I have updated the text strings in these to extra resource files, I get the error from the Assembly Linker:
AL1057 Executables cannot be localized, Culture should always be empty
The first time the linker fails to link my program, the second time it links and can be executed. It also
runs without any problems, so why this error!!
Whats the problem???

package and deploy VISUAL C++ 6 app with MFC - I AM SO DESPERATE!!!
I am trying DESPERATELY to package and deploy a visual c++ 6 application which uses MFC. My application runs without problem on the developer's (my) machine -windows xp. But I can't figure out how to make the app run on other people's machines which are also running XP!!!!
SHORT QUESTION:
How do I package a visual c++ 6 app? Do I need different versions for different OS's?
EXPLANATION:
First I tried to copy my app's .exe file to the other computer, run it, watched which DLL's it complained about, found them on the developer machine, and copied them to the target machine. That lame idea worked for awhile, and now my app just crashes.
So then I tried to do what I thought was the right way. I used depends.exe and redistrib.txt (or something) to figure out which DLL's I can (need?) to include (according to M$'s documentation). GULP! Does this mean I have to look at every single DLL and check to see if it's on the list!?!? There's over 50 DLL's for my SIMPLE project!! I used a free packaging tool to do this and it didn't seem like it was going to figure out which DLL's I need. There's gotta be a packager that figures out what stuff you need and puts them in a single MSI or exe file. If this exists, what is the cheapest one and what is it's name?

Web based Windows service management question
Hi .net gurus,
I need suggestion on the differents possibilities
THE NEED
------------
Web page that is able to stop/start different services on local AND
remote server.
Real life explanation : Those service are dedicated online game server
controled by
windows services. One for each
THE CONTEXT
------------
The page will be on only one server. The server will have access to an
MS-Access db that contain 3 tables.
1. USER_LIST : (username, password to acces the stop/start
page, full name, etc)
2. SERVICE_LIST : (description, servicename, serverIp, serverPort,
etc)
3. USER_SERVICE : Tables that contain the rights : who can access
what
NOTES
------------
1. Im using the ServiceController class to retreive and set the
services status
2. Login page and authetification is already made on the main
server.
3. Currently work on main local server
4. Use the XML attribute <authentification
impersonate=true></authetificate>
5. Using win2k dev pc with VS.Net 2002 while productions servers
will
be on Win 2000/2003 servers.
SOLUTION
------------
Create "Someting" that will be installed on each server we want
access to and
use the namespace nedded to interact between the main server web
page an the "Something"
"Something" could be
A) Windows service and socket namespace (socket, tcplistener,
tcpclient, etc;)
B) XML Web service
C) Remoting architecture
COMMENTS
------------
1. We need to make sure that access to other server have a decent
security
2. I want it to be the fastest possible. The main reason is that I
will retreive
info on multiple servers before presenting an available list to
the user.
Each reaload of the main we page will fetch all status
according to the
content of the USER_SERVICE table
3. An other alternative would be to use the ServiceController
class and connecting
to a remote machine when using the constructor. I tried and
never found a way
to make it working.
4. The asp.net web page is done with vb.net while the solution to
be installed on remote
server will be implemented in C#
------------
Mainly im asking what are the pro & cons of each solutions. I would
really appreciate
the community opinion on this. Im a long time VB6 devlopper and fairly
new to .net
TIA
