| mmm, I see why you say that, however, it's all code behind stuff and loading the listbox itself is not really using WPF as such. V.

I can reply the same thing to people voting me down: How to answer a question.[^]
It's not 100% correct to delete the message, but I did so in order to avoid discussion.
Apologies if it really is that wrong to do so.V.

How does this apply? The ones who marked you down were following the guidelines. You were not.

exactly, my question was certainly not poorly phrased, not inappropriate, no bad english. I certainly believed it belonged in the C# forum as it was IMO not 100% related to WPF and I was developing in C#.
There was no reason for voting me down, hence my reply to you.
Secondly, I apologized for removing the message, let's just stop the discussion and forget about it.V.

| Fair point. There seems to be too much willingness for people to spend time quibbling about things being in the wrong place and filling the forums up with arguments rather than insightful help. Regards,

You will probably get a better response in the COM forum.
It looks like the COM component (or the caller of the com component) is taking too long to respond. I don't know enough about COM to really held.Antoine de Saint-Exupery: Perfection is achieved, not when there is nothing more to add, but when there is nothing left to take away.

thanks for the reply I appreciate it (people started voting me down for what reason I don't know).
I did see the COM bit in the message, but it surprises me as I don't have any references to a COM object.
Makes me think that this error must be weird indeed.V.

You should only get this error when you run it through the Visual Studio debugger. Your release mode executable will not throw this error or message. Of course freezing up your main thread for over a minute may not be a good thing to do but I guess you can live with that if the user knows that it's to be expected.
See this blog entry[^] for more info on this.
Oh btw I think you posted this in the right forum. It's just that when you mentioned WPF some people got mislead (people try and answer everything here, even on topics they are not familiar with - it's a mad rush I guess to be the first one to answer. kinda keeps the forum response time fast, so it's all good I guess)

Thank you very much for your answer !
I'll definitely check it out.

Hi.
In my web site have forum.
Users can insert anything texts.I want enabled inserting just english chars and numbers, and disabled all other characters!
For example , in this forum any peoples writing native language(like arabian, parsian ,...) and how can disable it.
Thanks.  We are haven't bug,just temporarily undecided problems.

I would suggest that you could have a server side filter that will only accept messsages where a certain percentage of the message conforms to your policy. But saying 'English Only' is a bad option, do you accept café? What about allat?

Is it possible to have a nested class like this
class a : b
{
class a
{
}
}
I am curently working in a Maintenance project, i have decompiled some dll to know the coding nature inside it, there i saw similar kind of nested class. any of you have idea on this.modified on Wednesday, February 10, 2010 7:37 AM
|
|
|
|

No. (As you would have found out if you had tried it.)
You can't have the same name fro a class and a class member (which the nested class is assumed to be). The compiler will complain.
You can have:
class a : b
{
class c
{
}

yes i do know that Nested class name cannot be as same as its holding class, but when i tried to Decompile a DLL it show similar kind of code inside that,
Any idea on that
|
|
|
|

A nested class can contain anything, methods, fields, properties, events, etc.
I think I do not understand what you are having a problem with.
Can you try explaining what you are trying to do or having a problem with in more detail, please?If Barbie is so popular, why do you have to buy her friends?

When I publish my C# application using Visual Studio Express, and install it, it creates a ClickOnce Application Reference file on the desktop and in the Start Menu instead of just a normal .EXE file - and this is screwing up my File Associations. Could someone kindly suggest how I could have txt files etc opened in my application when dealing with Application Reference files?
Thank you
|
|
|
|
|
The real .exe file will be stored somewhere in the user's AppData folder (I think).
Why not have the associations set on first startup of the program? You could have your software enter the details in to the registry (note: potential permissions/UAC problem) as it will know exactly where it is.
|
|
|
|
|
Thank you - I have searched my entire hard drive in every possible place that there would be an executable file but have not found any. I even checked the AppData folder. Nothing at all. Just a bunch of ClickOnce Application Reference icons.
I also tried setting registry info for the associations on startup and it has been unsuccessful. I don't get any errors at all... It just doesn't work.
I've also (originally) tried using the File Association dialog that's inside the Publish page where you publish the project and entered ProgID info and icons etc and that approach hasn't worked either. But, funny thing... The custom Icons I used in the File Association dialog in VS are showing up on the files... My app just isn't loading the content of the files that are being double-clicked.

I have the following code:
using System;
using System.IO;
using System.Xml;
public class Sample {
public static void Main() {
string strQuery;
XmlDocument doc = new XmlDocument();
doc.Load("booksort.xml");
XmlNode book;
XmlNode root = doc.DocumentElement;
book=root.SelectSingleNode(strQuery);
}
}
In the call to SelectSingleNode, how do i formulate my strQuery so that I get the FileValue2 (in this case it is 'swethrhbfb') where FileValue1="00000002.dat"
Many thanks!
