I am developing multilingual application.
Font size for fields is 9.
It gives preview & print perfectly.
But, when i am exporting report to word. it resets font size to 12(for Hindi & Gujarati Font).
Also, when i am exporting report to PDF, it doesn't show Hindi & Gujarati Data.
I have checked same issue with 8,10,11 size font also, it always resets to 12.

I am also having the similar issue. in PDF, Hindi characters are not printed correctly.
And even when I print, it generates the PDF itself so I am having the same issue in print also. I tried to change print type to ActiveX but no success, it still printed in PDF format.
Have you found any solution to it?

This question maybe VB.Net specific, as I've never written interfaces using C#.
I have created an interface, IMine. When I create a class and add Implements IMine, the IDE automatically generates and inserts stubs to implement the interface.
I would like to add XML comments and DescriptionAttributes to the interface code to document what the various items are for, and have those comments and attributes auto-generated in the implementing class along with the stubs. Is there any way to do this?

They write that they have only "experimental" support for VB.NET, but you might want to look at GhostDoc[^]. GhostDoc will copy the comments on base classes and interfaces to the new child class.

Whenever I call Directory.Exists, it returns false, so I try and create it, and get an Access Denied. If it doesn't exist, the create works. I believe this is due to permissions, but I can delete, populate, and create directories, I just can't check if they exist. This is most puzzling.

Works for me running a C# Console app. under my domain account which of course has access to the location I was checking.

Hi,
from the symptoms you described, this could well be a bug in your code, failing to check existence
properly, and failing to create a directory that already exists (and was created by someone considered different from yourself).

Hello everybody in this forum , i would like to ask one question
i am developing a .Net remoting task , in which there is a server to publish a remote object that is registered on a definite port and a client which calls that remote object based on the remote uri of the remote object from the server .
now , in my task , when i run the server and the client , everything goes very well but i would like to run multiple client instances on the same machine .
when i do that it tells me "http channel is already registered" because in the client program i register an http channel but i would like to run multiple clients here is the code in the server.
<br />
HttpChannel channel = new HttpChannel(6064);<br />
<br />
ChannelServices.RegisterChannel(channel);<br />
<br />
RemotingConfiguration.RegisterWellKnownServiceType(typeof(RemotingManager), "RemotingManager.soap", WellKnownObjectMode.Singleton);<br />
and in the client side
<br />
<br />
HttpChannel mychannel = new HttpChannel();<br />
ChannelServices.RegisterChannel(mychannel);<br />
IRemotingManager mgr = (IRemotingManager)Activator.GetObjcet(typeof(IRemotingManager),"http://localhost:6064/RemotingManager.soap");<br />
......................<br />
.......................<br />
so when i run the client program it works so well and it fetches the remote object and everything goes well , but when i run multiple instances of the client program it tells me "the http channel is already registered" is there any way around that ?????
please help , i need to run multiple instances of the same client program on the same machine without having this port conflict ....
Thanks in advance.

What happens if you try to Activate the second instance after that error?
Also, it's not a good idea to post code that doesn't compile unless you are asking about a compiler error.
snouto wrote: Activator.GetObjcet
This tells us you did not post your actual code that executes since that won't even compile. Therefore we can't trust anything we are looking at.

sorry mike , it is activator.GetObject(...) , but you still didn't reply to me about the core problem not mistypo ....
Look Deeper inside the core not the pheriphery
thanks

The gold triangle says it is. He did answer your question - he asked you what happened if you tried to open the second object anyway. It is possible for multiple instances to talk to the same port - it is not possible for the same port to be opened up many times. Work your way round that issue and you will find the answer.

can you explain more please your answer . how can i open multiple instances to talk to the same port , you mean to create a tcpchannel and give it a specific port like
TCPChannel mychannel = new TcpChannel(3030);
for example .
or put a port in the httpchannel constructor , can you clarify using a demo line of code for that port section , thanks for you

Nice Post Pete O! Surely you have solved his problem! Let me look at his reply..
Oh dear, what a shame. 
Look at the time! It flies by when you're, ummm doing whatever this is. 
Have a great weekend dude! ![Beer | [beer]](https://www.codeproject.com/script/Forums/Images/beer.gif)

I need a XML parser which uses XML schema.Plz help.
|
|
|
|
|
If you mean that you need an XML parser that reads an XML schema, then you're in luck because an XML schema file is written in XML! Any ol' XML parser will do, including the one(s) in System.XML.
Now, if you mean that you want to validate an XML document against an XML schema, that's a whole 'nother ball of wax. A really good place to start is at Validating XML Data with XmlReader[^].

Hi,
I try to understand what is sync block index in reference type -
I google it and still did not find anything that explain it in way i understand.
Can someone please explain what is it ?
Thanks.

It's a very scary and 'under-the-hood' kind of thing. It appears to be an integer that is added to all (or some, sources don't agree) objects and has something to do with locking and the GC.
Before I go about unearthing huge PDF's containing detailed descriptions, is there there anything in particular that you'd like to know about it?

The SyncBlock is part of the .NET type internal structures (namely the OBJECTREF structure), and primarily has to do with thread synchronization. Generally, a SyncBlock is not created for classes, and the index # will be 0. If you use the lock() statement, then the CLR will create a SyncBlock entry for the current type, and associate it with the current AppDomain. When the lock block is entered, the CLR will create a Monitor object and stick it in the SyncBlock, along with the classes hash code (the AppDomainID and hash code are intended to support COM interop, and are not really used for pure managed code). The SyncBlock will then stay alive for the lifetime of its associated object and appdomain.
The SyncBlock index is a 1-based index into something called the Syncblk Entry Table, which is an indirection into the actual SyncBlock List which contains pointers to each SyncBlock instance. The reason for the multiple levels of indirection are intended to support the GC, which can freely move objects (such as SyncBlocks) around in memory. Each object instance itself contains a numeric 1-based index into the Syncblk Entry Table rather than a direct pointer so that the GC IS free to move SyncBlocks around in memory without requireing too much overhead to maintain type system integrity.

One difficulty with the normal exception system is that while it allows applications to use catch exceptions from which other exceptions are inherited, the normal exception hierarchy is based upon what type of problem occurred, rather than upon what the problem 'means'. An TimeoutException that occurs in one circumstance should probably be handled totally differently from one that occurs in another.
Although .Net allows one to define a custom hierarchy for one's own exceptions, each exception class needs to repeat the code for the four standard New() methods, and so creating a significant number of classes can be a nuisance.
One approach which would seem to hold some promise would be for an application to express its own exceptions using generic classes, something like:
Class GenEx
Inherits Exception
... New() methods here
End Class
Class GenEx(of T)
Inherits GenEx
... New() methods here
End Class
Class GenEx(of T, U)
Inherits GenEx(of T)
... New() methods here
End Class
Class GenEx(of T, U, V)
Inherits GenEx(of T, U)
... New() methods here
End Class
etc. if more nesting is desired.
Then if an object of type MyThing wants to throw an exception for a timeout condition, it can throw a New GenEx(of MyThing, TimeoutException) which can be caught by a Catch of either GenEx, GenEx(of MyThing), or GenEx(of MyThing, TimeoutException).
Things get a little clunky if MyThing is itself an inherited class; catch statements for GenEx(of MyThingsParent) won't catch a throw of type GenEx(of MyThing). In designing the throw statements for MyThing, however, one could throw a GenEx(of MyThingsParent, MyThing, TimeoutException) [though that would unfortunately only get snagged by a Catch of GenEx(of MyThingsParent) and not one of GenEx(of MyThingsParent, TimeoutException)] or a GenEx(of MyThingsParent, MyThing, TimeoutException) [ignoring the actual type of MyThing].
Has anyone else tried anything at all similar to this approach? With what effects (good or bad)?
Pro: it would facilitate a more useful exception hierarchy based upon the type of object trying to do something than upon the nature of the result.
Con: unless one had a procedure for cataloging the exceptions one was actually using, it could turn into a real mess.
Any thoughts?

Or possibly both. 
I dunno, I just tried the syntax in C# and got no errors, so it seems valid.
I just haven't yet thought of a use for it.
If you could come up with a situation in which to use it, you may be more convincing.
