Why on earth did you think this had anything at all to do with the C# forum? Please, in the future, don't randomly pick a topic to post in. However, you can download AVG[^] for free - that should take care of it.

hello, Can NHibernate exit your app without throwing an exception?
I'm debugging a console app and
<br />
void main(...)<br />
{<br />
try {<br />
IPerson oParent = LoadPerson(123);<br />
<br />
} catch(Exception ex)<br />
{<br />
Console.WriteLine(ex.ToString());
}<br />
return;<br />
}<br />
<br />
public IPerson LoadPerson(long nId)<br />
...<br />
try {<br />
<br />
<br />
using (oScope = new TransactionScope(TransactionScopeOption.Required))<br />
{<br />
IPerson oParent = Session.Get(nId);<br />
<br />
LoadChildren(oParent);<br />
<br />
foreach(IPerson oChild in oParent.Children)<br />
{<br />
oChild.Parent = oParent;
<br />
oChild.Parent = new Person();
<br />
}<br />
}<br />
<br />
} catch (Exception ex)<br />
{<br />
Console.WriteLine(ex.ToString());
}<br />
<br />
returns oParent;<br />
}<br />
Any suggestion as to posssibility of NHibernate causing my WIN32 console app to exit silently? I have catch(Exception) on all levels but still I didn't manage to catch any exception and therefore don't know what killed it... I initially suspected loading children is a recursive ops but if infinitely recursion was the cause of death I should have a StackOverflowException do I? But I have nothing. I understand you can't "catch" a StackOverflowException" but still if you run app on debugger, debugger will be able to tell you that under all circumstances right? (I tested this on another simple toy app)
I am most suspicious you can't really assigned oParent to Child.Parent attribute within same transaction scope - even though oParent loaded first.
<br />
oChild.Parent = oParent;<br />
Many thanks.

What you could do is download the source for NHibernate and debug your application with the source.

Hi,
I have installed VS 2005 last night. And build a simple C# Windows Application....I build this solution...the build is succeeded, but instead of output it prompts the following error message...
" The application failed to initialize the property (0xc000007b. Click OK to terminate the application ".
Please tell me how to solve this issue....Thanks in advance

A quick google search came up with the result that your pc is maybe infected with the WORM_KLEZ.E virus. To be sure about this, perform a virus scan.

A quicker google search revealed that the compiler comes with a debugger. Use it.

I am a beginner in C# Windows Application Development. I have developed an application with accounting package in three-tier architecture.
I am using a single static sql connection for entire application at present.
But I am not thinking it's a good practice. Please advise

Hi,
I thin you have a problem within your windows app, if it uses multi-threading. If you use transactions for example, running two or more transactions with one single connection will fail. But if you didn't use multi-threading within you app, everything should be okay. Problem will be when using your tiers within a web app (since the hosting is a single app with multi-threads for each session/request).
To be able to give you a more specific answer, you have to be more detailed about your app.
Regards
Sebastian

As I already mentioned, I am beginner and I have developed the three-tier application referring many links in the internet.
Eventhough my application can work on multi-user environment, now the customer is working only with one computer and works fine.
I have tested the same on two machines and works fine.
Please note my applications contains the following files
1. APPL.EXE // Contains only Menu and
3. FRONTEND.DLL // Front End Forms
2. BUSINESSLAYER.DLL // Business Layer
3. DATALAYER.DLL // Data Layer
4. REPORTS.DLL // Crystal Reports and Forms to view the same.
On loading Appl.exe, I am opening a static sqlConnection and using the static connection on datalayer.dll. This is because when I want to copy the application to another customer I have to change only the code on APPL.EXE. I have also implemented the same on using another class <myconnection> and works fine.
But I want to know when I have to implement the software on another computer, Whether I have to copy all the files to the second machine or copy the APPL.EXE file to the second machine and refer the DLL files on the Server.
If you want more details, please inform.

You can't refer to the DLL-files on the server. You have to copy all libraries to the pc of your customer. Since the app is running on this pc, there is no problem in using a static connection, since the connection is only used by the app on this pc.
But let us talk about the system design. If your intention is that only the frontend-library will be delivered to the customer you have to think about using a client/server architecture (web-frontend or sth with webservices). But pay attention when implementing this pattern, there you can't use a static connection since your server will use multiple threads and this won't work well with static variables.

Sebastian

THANK YOU VERY MUCH.....
As of now, since this is a small/ medium application, the current design may be OK.
If I want to copy only the font end, whether I should require individual connection.
I am asking this question because, if some of customer wants web front end, whether I have to change the entire back end code, because all the class on the same is using a single static sqlConnection.
Please advise.
Once again thanking you for your great advise.

Yes, if your customer wants a web-frontend you have to change your classes so that they are not using a single statice sqlConnection.

The data access layer is not supposed to know what the frontend and business logic layers are doing, or how they do it; hence it must allow for multi-threading and it should not be based on a single static DB connection.

I created a dll, and need support licensing.
now, i import IClassFactory2 interface,see:
http://www.pinvoke.net/default.aspx/Interfaces/IClassFactory2.html[^]
then use it in class:
public class HelloWorld: System.Windows.Forms.Control,IClassFactory2
please, how to realize this IClassFactory2?
and should i call procedure in HelloWorld create procedure?

It's a COM interface, not an interface in the sense of anything .NET. Using it, seems utterly insane to me. I get the feeling you googled 'C# license' and found this, but have no idea what it is. It's not going to create licensing code for you, I don't see any way that it helps you at all.
Don't forget that anyone can read your dll's source code with reflector, whatever licensing you decide to write.

IClassFactory2 is not like a .NET interface. To use it, you need to use the COM subsystem to get a reference to the class object present inside your COM object. The sample at the bottom of the page you linked to provides a bit more detail, but I would suggest that you need to read up on COM before you proceed any further.
As a side note - .NET assemblies (unless marked as COM objects) do not contain this interface.

Hi to all,
I want to create multiple documents or reports (Word Files or PDF Files) as following format,
Reference No:
Name:
----------- -------------- ---------------
Surname First Name Middle Name
Date Of Birth:
I have to fill the content in blan spaces.
How I can do above formmating while generating files?
In one forum, it is written to use StreamReader & StreamWriter classes to create formatted files.
How to use StreamWriter using content of a StreamReader (from a fixed file), to generate new formatted file?
Regards,

You can create an rtf file that ms word can read by doing the following:
string line;
using (StreamWriter writer = File.CreateText(@"C:\file.rtf"))
{
line = String.Format("Reference No: {0}", 3233);
writer.WriteLine(line);
writer.WriteLine();
line = String.Format("Name: {0}", "Ron");
writer.WriteLine(line);
writer.WriteLine();
//....
writer.Flush();
}

Thanks for suggestion.
With the help of your code, I have wriiten statements as follows,
line = String.Format("Name: {0} {1} {2}", txtLastName.Text, txtMiddleName.Text, txtFirstName.Text);<br />
writer.WriteLine(line);<br />
writer.WriteLine();<br />
line = String.Format("Date OF Birth: {0}", dtDateOfBirth.Value.ToString("dd-MMM-yyyy"));<br />
writer.WriteLine(line);<br />
writer.WriteLine();<br />
line = String.Format("Address: {0}", txtAddress.Text);<br />
writer.WriteLine(line);<br />
writer.WriteLine();<br />
writer.WriteLine();<br />
line = String.Format("Education: {0}", txtEducation.Text);<br />
writer.WriteLine(line);<br />
writer.WriteLine();<br />
writer.Flush();
Output file is as,
Name: ASD FGH JKL
Date OF Birth: 30-Feb-2009
Address: Block Number,
Area, City
PinCode
Education: Done School in 1999, with % of Marks.
Done PG in 2004 with % of marsk.</
But I want output file as with 'Justify' alignement,
Name: ASD FGH JKL
Date OF Birth: 30-Feb-2009
Address:
Block Number,
Area, City
PinCode
Education:
Done School in 1999, with % of Marks.
Done PG in 2004 with % of marsk.
How to do this?
Thanks & Regards,

I am not too familiar with rtf yet I can suggest an alternative (less elegant) solution: You simply add a tab char to your output string:
line = String.Format("Address:");
writer.WriteLine(line);
line = String.Format("\t{0}", txtAddress1.Text);
writer.WriteLine(line);
line = String.Format("\t{0}", txtAddress2.Text);
writer.WriteLine(line);

Thanks for the suggestion.
I tried it. But it is not going to work properly with a Paragraph (from multiple lines textbox).
Is there any formatting function availables with StreamWriter?
Else do you know how to use macro ( written by Microsoft Word in VB ) in C#?
Thanks & Regards,
Aniket A. Salunkhe

I do not have much input on both of your questions.
AS far as I know, formatting is done with string.Format and StringBuilder.AppendFormat which formatting wise is the same thing. I can suggest that you check what kind of char to inject to your string (like a paragraph mark) in rtf.
I have no experience using office marcos from code. You can look at MS Office Dev Tools or if you are using VS 2008 try an Office add in project.
You can also try reposting your question and give the options you are trying (rtf, macro etc.)
I am interested in hearing the solution you find.
I hope this helps
