Hi all,
This week I’ve been doing research on wcf but I’m a bit confused heres my question ....
If I have a wcf service with http transport containing a method called send mail that method uses system.net mail class to send email via smtp wont it be using the underlying mechanics to send an email using smtp via tcp.
|

The System.Net.Mail class has nothing to do with WCF as far as I know and so will do it's usual SMPT over TCP thing.
The WCF transport only applies to the WCF stuff.

Hi all,
Right we have application using Microsoft Visual C# 2.0.
Application divided by two programs
1. Win forms
2. Console Application.
We already completed that program using C# 2.0.
Console application, I like to run as a windows service or command line. (It’s depends on the user option).
How can I run a console application as command line or windows service?
[I don’t want separate EXE for console or windows service, I need to run one EXE as a Console or Windows Service).
How can I implement this functionality?
Kindly let me know the technical idea or sample code for that.
Thank you,
Sundar.

It would probably be easier to have 2 seperate apps that just use the same code from a shared lib.
I really think it would be more trouble than it's worth trying to have the single exe, and for very little gain.
A service needs to be installed, so the application would have to install itself depending on the supplied options, you'd probably also need to add in code to ensure that multiple copies can't be run and more code to handle the controlling of the service. All of which can be easily avoided.

Hi,
Thanks for prompt reply.
I have suggested the same opinion to my mentor (client).
But he wants one single program, run as a command line or windows service.
Already my client developed the console application run a command line. Now I am making the enhancement for that application.
Thank you.

Why not make two separate dll files, one is for command line and the other a service. Then all the exe has to do is determine which one to run, then invoke the proper dll. It meets your customer's spec of only having one exe, while making implementing it easy on you.

Hi guys!
I'm trying to install a printer driver via WMI and C#
I can invoke the method but always get a "87" (invalid parameter) as return value.
But I have absolutly no idea what could be wrong with the parameter (I suppose that it's the "DriverInfo" param).
<br />
ManagementClass classInstance = new ManagementClass("root\\CIMV2", "Win32_PrinterDriver", null);<br />
<br />
ManagementObject driverInfo = classInstance.CreateInstance();<br />
driverInfo["Name"] = "Adobe Postscript 5";<br />
driverInfo["Version"] = "3";<br />
driverInfo["SupportedPlatform"] = "Windows NT x86";<br />
driverInfo["DataFile"] = "C:\\Temp\\adobe\\DEFPRTR2.PPD";<br />
driverInfo["ConfigFile"] = "C:\\Temp\\adobe\\PS5UI.DLL";<br />
driverInfo["DriverPath"] = "C:\\Temp\\adobe\\PSCRIPT5.DLL";<br />
driverInfo["HelpFile"] = "C:\\Temp\\adobe\\PSCRIPT.HLP";<br />
string[] depfiles = {"C:\\Temp\\adobe\\PSCRIPT.NTF", "C:\\Temp\\adobe\\PSCRPTFE.NTF"};<br />
driverInfo["DependentFiles"] = depfiles;<br />
<br />
ManagementBaseObject inParams = classInstance.GetMethodParameters("AddPrinterDriver");<br />
<br />
inParams["DriverInfo"] = driverInfo;<br />
<br />
ManagementBaseObject outParams = classInstance.InvokeMethod("AddPrinterDriver", inParams, null);<br />
<br />
Console.WriteLine("Out parameters:");<br />
Console.WriteLine("ReturnValue: " + outParams["ReturnValue"]);<br />
Perhaps someone can help me?

I'm working on some peer-to-peer stuff and I need to make this service available to those behind routers. Two things need to be accomplished:
1. Detect whether or not the user is behind a router.
2. If the user is behind a router, forward port X to the user's network IP.
I've seen this done using COM and C, but I can't translate into C#.
Thanks!

UPnP is very handy for this. Having a quick search around I came across this code:
http://www.thescripts.com/forum/thread431643.html[^]
if you pick your way through that and understand it you can probably use it as the basis for any other UPnP stuff you need (although that might cover it all).

"p (precision)
Specifies the maximum total number of decimal digits that can be stored, both to the left and to the right of the decimal point. The precision must be a value from 1 through the maximum precision. The maximum precision is 38. The default precision is 18.
s (scale)
Specifies the maximum number of decimal digits that can be stored to the right of the decimal point. Scale must be a value from 0 through p. Scale can be specified only if precision is specified. The default scale is 0; therefore, 0 <= s <= p. Maximum storage sizes vary, based on the precision."

I'm using Microsofts implementation of ripemd 160, as declared in System.Security.Cryptography. It produces different results when run on Windows XP and server 2003.
I needed to test an application via RDP on a 2003 machine and noticed that the hashes produced was not coherent with the ones I got when using windows XP.
Is this a known bug or am I doing something wrong? Please let me know if you need additional information.

Bumping the thread and correcting myself.
After some serious tracing I have concluded that the problem is regarding the byte order in win2003. The problem appears when translating the byte array from the hash to a integer. The hashbytes correspond to eachother.
I cant seem to find a workaround for this problem. Does anybody have one?

Any one help me that , I have 2 files i.e File1 & File2.
My objective is to append all the contents of File2 into the preexisting File1.
With Regards

File.AppendAllText("File1",File.ReadAllText("File2"));
If your files are at different locations, you will need to specify full path

I created Check Boxes in Property Grid using UITypeEditor. I also need to create Property items dynamically , so I used Custom Property creation using PropertyDescriptor class adn created properties using CreateProoperty.
The problem is: After using CustomProperty descriptor I am no longer able to see checkboxes or listBoxes created using UIType Editor .
Any one have faced this problem before ? How to use UITypeEditor and PropertyDescriptor together in my class and does not lose the UITypeEditor visual (checkboxes, Listboxes)
Cheers,
Rajan

Typically the editor is defined as an attribute on the property. Since you are dynamically adding properties, then you would either need to manually create and add the attribute to the PropertyDescriptor, or simply override the GetEditor[^] method.
Take care,
Tom

Hello.
I'm having a bit of problem with a service written in C#. It starts just fine under Windows XP and Vista. But when i try to run it under Windows 2000 (server) the service just hangs on startup.
The service is set to run as LocalSystem, and the only thing it does in the OnStart()-method is to spawn a worker-thread that is supposed to do all work. However the OnStart()-method doesnt even trigger. I've added a couple of trace-points using EventLog.WriteEntry() to see how far the service comes when its starting.
Seem to hang on the call to ServiceBase.Run(servicesToRun); Sometimes the EventLog states that the service hung on startup, but no further info is provided (and the service can still bee seen as "starting" in the service manager).
Does someone here know whats going on? And how to fix it?

Have you tried running it as a console app to see if it's the code or if it's because it's a service?
9 times out of 10 I find it is the fact that it's running as a service :/ but atleast then you'll know for sure.
Theres always the old fall back of putting
MessageBox.Show("1");
//line of code
MessageBox.Show("2");
//line of code
MessageBox.Show("3");
then setting the service to allow interaction with the desktop, this will allow you identify the exact line of failiure.
Another option is putting in Thread.Sleep(10000); somewhere near the start of the service ... this gives you a bit of time to attach to the process so you can properly debug it. Of course it also eats up part of your 30 second timeout before the service will be reported as failed.

Havent tried to run it as a normal application yet. Will do that later.
The good old trick of constant output is what I've been trying. Just before the call to ServiceBase.Run(servicesToRun); I'm callin EventLog.WriteEvent() and the first thing that is done in the OnStart()-handler is to write another entry in the event log.. That second entry never appears in the log however... But just to be sure, I will try your example with letting the application interact with the desktop.
Using remote debugging reveals tow threads, one without a traceable stack and one thread being stuck on the ServiceBase.Run(servicesToRun)-call.
